I believe the key to safety is understanding the tools and their potential for danger.  That is why I like to show novices what can happen with flying boards, etc. and the importance of keeping body parts out of harms way.  

I've had too many problems with splitters and factory supplied guards, but the best bet if you are not confident of what you are doing is to use one and put up with the inconvenience.  The only time I have ever had an "accident" with any of my tools (including chainsaws) is when I attemped to cut a tiny board  with the blade up only about 1/4".   It resulted in a nick to my middle finger.  I use a variety of pushers to keep my hands away from danger.   I have also demonstrated to myself and others the hazards of kickbacks and flying boards.  I think this makes a lasting impression on novices learning the use of these powerful tools.

I made up another scarf jig for the radial saw  This one lays flat on the table and has a groove cut to a depth down to the top of the fence.  I did this so the stock could pass over the top of the fence thereby allowing the cut to be made in the middle of the stock.  The angle is set so that the stock will not interfer with the column of the saw.   I use this to rough cut the stock and then finish up cutting a parallel trim cut with the jig shown in the previous posting.  The reality is that with a little bit of care this may be unnecessary.   The guard on the radial saw has been tilted back for clarity when taking the photo.  Of course you would need clearance behind the saw to cut in the middle of a long stringer.  

I received a small sample of 8oz poly with about 50-60 threads/inch.  I tested it by ironing and it shrinks about 10% (and even more if you get it too hot).   I tried painting it with an oil based paint and it seems to nicely take the paint.  I put a second coat on and believe that would seal it.   But, as this is new to me, I have nothing to compare it to..  Anyway, I won't be working on my kayak until this summer when I go to Washington, so I thought doing some research might turn up something.   But, now as it turns out, the supplier has run out of the material and is no longer offering it for sale.  

Just wondering what the specs are for polyester.  8oz/yd? Is there any reason to go heavier or lighter?  What is the ideal thread count?  Uncoated.  How does one tell if it is coated or not?  Any other relevant specs?
