Crawling out from under the porch and dusting myself off...
I made a different type of mitre jack a few years ago when I was making some
furniture with triple miter joints. Wiktor was kind enough to host my story
about this on his website:
http://www.wkfinetools.com/tMaking/art/miterJack/miterJack-1.asp
This worked really well and I don't think I could have gotten these joints
to fit properly without it.
For the last couple of years I have been working on building bamboo fly
rods. Just finished my fifth one and I feel like I am still on the steep
part of the learning curve. I've gotten to the point where I can enjoy
using them for fishing, but still have a ways to go before I could ever
charge money for one.
The assembled bamboo rod has a hexagonal cross section and is made of 6
strips which have an equilateral triangle section. The grooved block plane
used for planing these on the steel form has a groove which is 0.003 inches
deep. This allows the plane to be used on the form without planing into the
surface of the form. I only use this plane for the final passes, using a
Stanley #18 for taking off most of the material to that point. A key point
about using the grooved plane for this application is that the groove must
be wider than the strip which is being planed. I don't know that this would
be the case when using a grooved plane on a miter jack? This restriction
would limit the stock to be less than about 2/3 the width of the plane sole.
Best Regards,
Ted, who is still around, just not speaking up very often.
