NatureMill - Clip Fix update

nospam@example.com (David Tapley) — Tue, 08 Jul 2008 11:23:31 -0700

Looks like the 'clip fix' failed. The unit still refuses to transfer waste from the top chamber to the collection tray.

The issue seems to be the design of the clips. The new ones have been bent over by the mixing arm, but the arm needs to catch on the clips when it transfers.

NatureMill are aware of the problem and have some new clips in development and in an email they have promised to ship me free replacement ones when they are ready. However they are not due until August so it looks like the NatureMill experiment is on hold for a few weeks.

I'll update you all when they come through.

NatureMill - Clip Fix

nospam@example.com (David Tapley) — Mon, 30 Jun 2008 19:43:00 -0700

This weekend I replaced the broken clips which had caused a problem with the NatureMill. The machine had stopped transferring waste from the top compartment to the bottom.

The replacement clips arrived via UPS from the States, sent directly from the clip manufacturer. NatureMill had emailed me the instructions for replacement. Before starting the repair I dumped it's contents on our compost heap and hosed the machine down to try and make the job as pleasant as possible.

The instructions were mostly fine, and taking the machine apart went OK. The only 'issue' was how the new clips actually fitted. The old ones had completely broken and there was no hint as to how the new ones went in. In the end I had to refer back to the photo's I took when the unit arrived and luckily there was one which gave the answer.

Fitting the clips was OK once I'd managed to free up the trap door. The main thing is not to accidentally throw out the small plastic grommets which help secure the clips with a friction fit. The instructions also suggest ensuring the trapdoor 'arms' are parallel, so I checked and bent them as required.

Reassembly is disassembly in reverse. Because I'd hosed the unit down I decided to restart the composting process from scratch and I reset the NatureMill when I powered it up. I added some chippings and soil and eventually the machine went in to 'Mix' mode. The the clips seem to have held OK.

The real test will be if the transfer function works and how long the clips last for. 4 months is the record so far. Fingers crossed !

NatureMill - Good News and Bad News

nospam@example.com (David Tapley) — Sun, 22 Jun 2008 21:13:02 -0700

Good news on the Nature Mill. I've been testing the unit with an alternative to the saw dust I bought after the saw dust pellets which shipped with the machine ran out.

When the original pellets ran out I popped down the local pet shop and picked up a bag of sawdust for pet bedding. However it seems that this type of sawdust isn't helping the smell issues I've been having with the Nature Mill. I'm unsure as to why, other than perhaps its pine softwood.

During the Winter I had a couple of big Pear trees behind the house heavily pruned and the Ivy removed. The job left behind a large pile of finely cut wood chippings which have started to compost down. So I fed the Nature Mill with a couple hand fulls from the chippings pile and the results have been encouraging. A smell is still there when the lid is opened but it's a bit more pleasant.

The bad news is that the machine has stopped transferring from the top chamber to the bottom one which means that I've not been able to test the wood chippings over a full cycle. I found a broken clip which must the the cause of the problem.

The good news is that the Nature Mill company in the US have been very helpful and redesigned replacement clips are on their way. The guys emailed the instructions for replacing them but it looks a messy job as the unit has to come apart.

I'll let you know how it goes . . . . .

The chippings pile from the Pear Tree and Ivy pruning. Hard wood rules for the NatureMill......Maybe !

Avalanche Accident Prevention Card

nospam@example.com (David Tapley) — Wed, 18 Jun 2008 16:05:36 -0700

Earlier in the year I took part in some research for the Canadian Avalanche Centre who in collaboration with the Simon Fraser University were conducting a study on avalanche awareness of out-of-bounds skiers and snowboarders. The goal is to develop better avalanche awareness materials for this group.

Analysis of the data collected is ongoing but as a thank you they sent me a copy of their pocket book and reminder card entitled "Avaluator" which was based on initial research cumulating in 2006. I received mine in the post yesterday and it looks to be a useful tool to aid decision making and a check list for those venturing off piste.

Obviously this type of publication is no substitute for training and using a guide but it aims to provide skiers and boarders with a tool which will enable them to avoid obvious mistakes and "set them on a path of learning and practising good habits".

For more information see the Canadian Avalanche Centre web site at:

http://www.avalanche.ca/default.aspx?DN=428,4,558,3,Documents

And Pascal Haegeli's site at:

http://www.avisualanche.ca/adfar1/avaluator.html

Update:

Following a couple of emails to Pascal, he comments:

"The Avaluator combines two methods for personal risk management on backcountry trips in avalanche terrain.

The Trip Planner allows the user to pick reasonable trip destinations based on the regional danger rating from the avalanche bulletin and a trip rating that expresses the exposure of the trip to avalanche hazard in general. For more background in terrain ratings visit:

http://www.pc.gc.ca/pn-np/ab/banff/visit/visit7a1_e.asp
http://www.avalanche.ca/default.aspx?DN=646,428,4,558,3,Documents

The Obvious Clue Method was developed by Ian McCammon based on US avalanche accident data. The idea is that the more clues are present, the more similar your situation to past avalanche accidents. You can find more background on this method in the following papers:

http://www.avisualanche.ca/downloads/2004_ISSW_DecisionFrameworks.pdf
http://www.avisualanche.ca/downloads/2006_ISSW_McCammonHaegeli.pdf
http://avalancheinfo.net/ADFAR%20Proj%20Docs/CAAReviewEuropeanDecisionFrameworks.pdf

There are two parts to the recommendations of the Avaluator:

1) The colors on the Trip Planner Chart and the Obvious Clue Scale (green-yellow-red) are expert recommendations about what level of training and experience is necessary to safely travel in avalanche terrain under the given conditions.

2) In the booklet we also provide estimates on the percentage of historic US avalanche accident that could have been prevented if the accident parties would have followed these guidelines. A comparison of US and Canadian avalanche accidents showed that their characteristics are comparable and these percentages are applicable in Canada as well.

So while the Avaluator contains some common sense recommendations, the user should be aware that the recommendations were developed by North American experts and that the percentage of prevented accidents is based on North American accident statistics.

The Avaluator does not have any capabilities to predict individual avalanches. It is built on historic avalanche accidents from North America and its goal is to make users aware of conditions that have resulted in accidents in the past. The recommendations of the Avaluator provide the users with a sense of how much training and experience is necessary to safely travel in avalanche terrain under different conditions. The Avaluator provides a new accident perspective to complement the existing avalanche safety methods such as snow science, group management and rescue skills."

Stairs, Feedback and Skiing.

nospam@example.com (David Tapley) — Fri, 06 Jun 2008 17:29:16 -0700

Winter and skiing seem a long way away sitting here with the sun shining and a gentle breeze blowing across the garden.

Even though it's early Summer there are things we can do to help set up our skiing for the Winter. Perhaps one of the simplest is walking up the stairs. It's the perfect chance to develop a key skill which will speed your up skiing development, it's free and one no one need know !

In order to climb the stairs you need to use your legs effectively, as you do when skiing. Because you've been walking up stairs quite successfully for years it's likely you don't give it a second thought, but if you think about it the movements you make are actually quite complex.

So the next time you walk up the stairs try and pay close attention to feelings you get from your feet and legs. Are you stomping ? Is your footfall soft ? Where are your feet landing ? Does the left feel different to the right ? Use all the 'feedback' mechanisms available to you. Feel, listen and maybe take a quick look at what's going on too.

Then walk up the stairs again. This time modify your movements based on what you have just felt. Maybe make your steps softer, or their placement more accurate. Or if you noticed a difference between the left and the right see if you can even it up. Each time you walk up the stairs or go for a walk, try and be aware of your footfall and how your legs are moving.

This simple activity helps you develop your 'internal' feedback skills, in this case a heightened awareness of what your legs and feet are doing. This is a key skill which will help you improve your skiing. By accurately feeling what's happening under your feet means that you are able to modify your movements and make fine adjustments, and then feel the difference.

When you get back on skis this will pay dividends. Your heightened awareness of whats happening under your feet will enable you to know better how you are skiing. You can then change how you are skiing and feel the difference. When working with your ski Coach or Instructor you will be able to compare your 'internal' feedback, i.e. how your performance felt to you, to your Coaches verbal feedback, how your run it looked to him.

By having more accurate information and a fuller understanding of how you are skiing you will be able to progress faster.

Negative Reinforcement in skiing

nospam@example.com (David Tapley) — Fri, 16 May 2008 00:32:34 -0700

I just caught a section of Derren Brown's 'trick or treat' program on Channel 4 and the theme was negative reinforcement.

He was conducting an experiment with a tight rope walker, a good one at that, not only could he walk a tight rope, he could skip at the same time. . . . . . .

After seeing the guy do his stuff on the high wire Derren Brown asked him to repeat the performance, BUT while thinking "I must NOT fall". The "Do NOT fall" message was reinforced by adding an inflatable crash mat and Derren Brown repeated the instruction "Do NOT fall" several times and just before he started.

Guess what ?

The same tight rope walker who had a moment ago walked the high wire, skipped with a skipping rope and all without any safety net "went to pot". His balance was poor, his movements less accurate and eventually he fell to the mat.

This graphically demonstrates how focusing on a negative element of your performance simply reinforces that negative. In the case of the tight rope walker, focusing on "not falling" caused him to eventually fall.

So in a simple skiing example, when your ski instructor says "Don't let your hands drop back" and you keep that as your focus on your next run, as likely as not you'll end up doing exactly the thing you were trying to avoid and the instructor was trying to address.

For success it's far more effective to focus on the positive. In the case of the "hands" a more helpful instruction from the Instructor, and focus for you could be "Keep your hands forward".

It's all to easy for instructors to fall into the trap of using 'Negative' instructions with their clients, so should your Instructor say "don't do" such and such, gently turn the request around and ask them to tell you what you should be doing !

ps. It should be possible to see the program again for 30 days using C4s on demand service - see http://www.4od.com

NatureMill Update

nospam@example.com (David Tapley) — Tue, 29 Apr 2008 13:06:15 -0700

It's been a few weeks since my last NatureMill update. The main reason for this is that I've had little positive to report.

Since restarting the machine in February after our holidays I've not been able to get it working 'as advertised'.

There are 2 issues, the main one being the smell. While most of the time the machine does not smell, boy does it pong when you put something in. The other problem is condensation which results in wet compost and gets into the air filter, which possibly contributes to making the smell worse.

I've contacted the NatureMill guys in the USA for guidance on several occasions, but the response is much same each time "Add more sawdust and baking soda". Just to be sure I've reset the machine, started the 'cultures' from fresh with soil from the garden and left it to settle for a week with out adding food.

According to the instructions you need to add 2 tablespoons of baking soda and a couple of hand fulls of sawdust at the start of each compost batch. I'm adding sawdust and baking soda pretty much every other time we add waste. As there are just 2 of us we don't produce much, adding mostly bread, some peelings or veg that's gone over in the fridge. With light use compared to a family the extra sawdust and soda seems a little excessive, and worse seems to make no difference.

We have produced a few batches of compost, but it looks nothing like the compost in the NatureMill video. It's wet and I'd be loathed to put my hands in it. I've been adding it to my garden compost bins to kick start the grass clippings but it's too early to say if it helps.

All in all at $300 the NatureMill has been disappointing. I'll carry on using it, as the smell is not too much of a problem in our Veranda (and I can't very well ship it back to the states) but I could not recommend having one in a kitchen or small apartment. In our experience the pong will be too much !

Before the NatureMill arrived we used a low-tech solution, a mini bin from Ikea. The lid seems airtight, there were no smells, and it held our green waste until the weekend when I added it to the garden compost bin. Best of all it offers a saving of $290 over a NatureMill

Lot's of cooked food waste ? Buy Chickens ?

Stepping Stones

nospam@example.com (David Tapley) — Fri, 25 Apr 2008 15:56:18 -0700

Top golfers use 'stepping stones' !

Watching BBC Breakfast over my toast and coffee the other morning, the program switched into sports mode with an interview with Justin Rose the top English golfer competing in the US Masters.

Justin, currently ranked top European and 9th in the World was being interviewed about his excellent start to the event, topping the leader board after the 1st day.

During the interview he described how winning major tournaments such as the US Masters was his long term career goal and how he has broken this goal down into smaller goals, winning specific tournaments of increasing importance.

I nearly choked on my coffee when he described these intermediate goals as 'stepping stones'. This is exactly the same way as I describe the goal setting process to my skiing clients and on my web site.

The idea is to break down a 'big' goal into smaller, more achievable sub goals (or stepping stones) which lead you towards the 'big' one. These stepping stones cover not just outcomes or results but also incorporate elements such as technique, equipment, fitness, tactics or psychology depending on your relative position to your 'big' goal.

Justin was also using the 'stepping stone' idea to manage the possibility of not winning at the Masters. During the interview he stated that he still had a few steps to go before he expected to win events such as the Masters - not that it wouldn't be nice. This meant he could try his best for the win without too much self imposed pressure, as should he loose, he still had his pre planned 'stepping stones' which will lead him to success.

The great thing for skiers everywhere is that this approach is not confined to top level sports people but available to everyone. Start now - decide what your 'big' goal is and take it from there !

My Golf is the perfect candidate for a few Stepping Stones...

Almost there ?

Focus and Concentration in skiing

Snow, Sky, Snow, Crash. It had been going so well, I was just 2 gates from the end of a GS race course.

The race in question being part of the qualification process for a ski instructor licence. The idea is to ski the GS course within a percentage time set by a pro ski racer. You get 2 go's and the best time counts. The first run was going fantastically and a few gates from the end I found myself thinking "bloody hell, I've nearly done this, just let it be over!"

The next thing I knew, it was. I'd crashed head over heals trying to make the the penultimate gate, so it was back to the top for a final go. I knew I could do it as I'd still got several seconds in hand while recovering after the crash. The second run started 'so so' and I found myself on wrong the line through the 'easy' top gates. This wasn't going well . . . . . . .

The thing is, 'technically' I was easily capable of skiing the course within the time required. My equipment was good and I had the right tactics worked out for the course but my 'head' was not so good. It was not a confidence issue or a problem dealing with the 'pressure', but the lack of concentration & focus. Prior to the crash I had switched my focus from skiing the correct line through the gates to "just finishing" and at the start of the second run I wasn't focused at all, "just skiing".

This is a problem for many recreational skiers (and participents of other sports) when they encounter tricker slopes or challenging conditions:

A good friend and fellow coach often comments that when he's skiing powder his run goes really well, up until the point he thinks "I can't believe how well this is going" at which point he takes a fall !
During one of my race training runs I was surprised by an unexpected shadow on the course (it was immediately after lunch). I thought "ah, I'm going into shadow - this could be tricky" and promptly missed the next gate as a result. Doh !
More randomly I once found myself circulating Oulton Park race circuit on a 250cc race bike thinking "I wonder what's for tea" !!!!

As well as being intrusive and changing your focus, these thoughts often have negative connotations:

When things ate going well, the idea forms that your performance would normally be 'worse'.
I may not finish the race or loose the game.
This is going to be hard or tricky.
or just not paying attention.

Luckily once you become aware of this type of thought it's easy to recognise. When they do pop up it's simply a case re focusing on the task to hand. The line through gates in case of my race or linking the next turns together for my powder friend. It worked for me in my race test, and I finished 5th and made the time.

Kebab and Chips please !

On the Level ?

nospam@example.com (David Tapley) — Thu, 06 Mar 2008 16:09:28 -0800

Well, the second batch of NatureMill compost is on my vegetable patch waiting to the dug in.

Unfortunately I had to start the NatureMill from scratch after our recent holiday. While we were away the unit was accidentally switched off which put a stop to the composting Bactria as the machine cooled down. On our return I reset the NatureMill and started from scratch, but keeping the existing batch half composted waste in the machine. The result was a second batch of compost which was quite wet.

I've got high hopes for the next batch and having re-read the instructions I've done a couple of things which should improve the performance of the machine:

* Added far more Sawdust (bought from a petshop) and Baking Soda to keep the optimum balance for the composting Bactria to offset the Bread, Lettuce, Citrus fruit & Potato combination of food we've been feeding the NatureMill.

* Leveled the machine to offset the uneven floor in our pantry and ensure the NatureMill Drains correctly.

An interview with Russ Cohn, President of NatureMill

A little history !

Russ Cohn, inventor and developer of NatureMill started the NatureMill indoor composting project back in 2003. The product has been evolving and improving ever since. Here is an interview with back in 2004 giving an overview of the early development and testing process:

Ski Instructor Judgment.

nospam@example.com (David Tapley) — Tue, 19 Feb 2008 17:14:28 -0800

I was recently asked to give some feedback to a couple of fellow instructors.

The first is planning to take their next instructing qualification and wanted a view on their current 'technical' level while the second asked for my thoughts after shadowing his Carving workshop for ski school clients.

Watching both Instructors was thought provoking and hopefully proved very positive for everybody concerned.

One thing that struck me during the week is the importance for Instructors to be able to match the best available slope to the learner skiers ability and the skiing activity planned. This is a fundamental skill for an instructor and is based on the ability to accurately judge the many variables involved, and is a key to a positive outcome for their clients.

The impact of these decisions for skiers in early the stages of learning is even more critical, and is complicated by the lift & piste combinations available in the resort. There are plenty of anecdotes about instructors who have pushed their clients too hard, too soon with negative results. A good instructor will not be afraid to return to easier slopes if need be.

Some resorts are extremely learner friendly and offer an excellent progression of slopes for beginners. Pila in the Aosta Valley Italy and Baqueira in Spanish Pyrenees are excellent resorts offering good piste progression giving lots of options for Instructors and skiers alike.

Sun Glasses

nospam@example.com (David Tapley) — Mon, 18 Feb 2008 16:32:47 -0800

I found myself unexpectedly taking a class last week in the Pyrenees. The group was a Mother and 3 kids, the youngest only aged 5 or so. I was shocked to realise that non were wearing Sun Glasses or Goggles. When I mentioned that it would be a good idea to put them on it became clear that they had been left in the car.

The Mother and later the Father were unconcerned at the potential damage the sun was doing so I called the lesson to an early end.

Bright sun, high altitude and unprotected eyes don't mix !

During my 06/07 Baqueira Winter season we stayed in a lovely apartment in the village of Garos. Garos is about 1/3 of the way up the valley from the main town of Vielha and the drive up to Baqueira takes around 15 minutes in the car (a fiat Panda in our case!). A Bus service runs up and down the valley and the bus stop is about 3 minutes from the apartment with a convenient 8.15 bus getting me to the Tuc Blac at 8.40 ish in time for coffee before ski school.
