Re: [bolger] Mast Gauge ?
Leander,
The Michalak picture tells alot of the story, and looks good, but you may
want to know about making one slightly larger for your 3 inch masts. The key to
an 8 sider are the distances from the sides to the pencils, and the distance
between the 2 pencils. If my crude drawing came out below, this is the distance
A and the distance B. When I made my spar gauges, I measured these distances in
millimeters, just because it made the math easier.
Basically, the formula is:
2 2 2
A + A = B
I'm no math wiz, so I just whipped out the old calculator. For example, if A
=30mm, then
2 2
30 + 30 = 1800
square root of 1800 = 42.4 so B = 42.4
this gives you a total distance between the edges of the spar guage of 30 + 30 +
42.4mm = 102.4 or 4.03 inches, which might work out for you. If not, just
pick a smaller number, and run the calculations again....
Also, make sure the side thingy's are pointy, as Michalak points out in his
drawing. If not the distances get all messed up and your mast won't come out
right. My Micro masts are only 8 sided, so I didn't make a 16 siding jig, but
the process is similar (I just don't have the energy to think about it right
now, sorry ;-( Another thought is to only put in one pencil, run it down the
mast, turn the guage around the other way, and then run it down again. It's
easier to keep one pencil on the wood than 2, and it still turns out just
fine....
Have fun!!!

Leander,
There is a picture and explanation of design for an eight sider in the back
of one of payson books, I can't rember which one and I'm at work. Also there
is a picture of an eightsider in an article at the following site.

It is an eight sider for making oars, but the design is the same i would
think.

like there is 50% to go.
