The wheel is 36" dia., .3125" thick and has a 14" hole in the center and

six equidistant mounting holes .375 dia. 1" from center hole. There

triangular tooth that is a radian and the other leg is 60 degrees.



I see doing them with a hacksaw and a file after blued and laid out by

hand. (maybe a power saw) Any better ideas? I can't visualize mounting

it on the BP.





Hire a machinist :-)





Ain't that cheating?



Not really. I think I'd hire a welder if I was building a bridge.



Actually, since you posted the original message on the 4th and today

is the 5th, one would assume that the job would be finished already

:-)





I have a LOT to do on this machine, the ratchet wheel is near the end,

I'm just thinking ahead. There is still a small chance I can get a used

one cheap. It fits a standard machine that makes different products

according to the number of teeth, each tooth corresponds to a position

on an X-Y table. The machine makes wooden block wire brushes, I have 16

of these machines, think 2-ton sewing machine. This one will make a

6x19 row, the extra teeth are for resetting to the first position. I

already have a machine to make this but I need to double production so

I'm duplicating all that is involved in the set-up which involves table,

holders cams and ratchet wheel. About three man-months of work.

For under $50 you can have this cut out wither as laser or a water jet...
I just got two jobs done at two different shops, about the same size.
One was water jetted, and one was lasered. Both jobs under $50.
The laser shop was two disks and that included the material.....
Seriously, you cannot afford to do this job yourself!
Quit screwing around and make brushes. The laser shops will not compete with you making brushes.
