Finding "rack threads"

[ndav8r]

Hi Gang:
I am in the process of building a homemade arbor press for my internal keyway broach set, and was wondering where I can locate the rack threads for it? Or maybe any other ideas for building a small press for my broaches?
Thanks!

Try checking with your local bearing house. All the larger ones ( Kaman Bearing, Bearings Inc., etc) carry a line of gearing components.
If that's no good do a search for Browning Gears I know they offer gear rack.

I tried to do what your attempting,buy a rack and building a press.It didn't work,not because of anything I did,it just turned out that I could buy a good used arbor press off Ebay including shipping for less than I could build one.

If your determined to build one,then assuming you have a mill the best bet is to mill your own rack.

What weirdscience said...Plus,

Those things are made out of heavy cast iron for a reason. The frame is cast and designed to not flex under tons of pressure. Unless you can cast your own, or have a friend with a foundry, you're chasing your tail on this one.

www.mscdirect.com lists spur gears and racks in a variety of pitches and 4 or 6' lengths for the racks. Haven't looked, but would be surprised if MCMaster didn't have it as well.
