Picked up this dremel bit at the flea market for 2 bucks and ground the teeth to a v shape

Good investment of 2 bucks.

Chuck,
I picked up the same dremel bit at the hardware store and ground it down on my bench grinder. I just haven't gotten around to finishing up my live threading jig.
I'm glad to see I might be on the right track.
Thanks for posting,
Gary

You're off to a good start!

In the picture it looks like you cut the threads going in, and then maybe backed it out still cutting the threads? The reason I say this is because they appear to be double cut. If you cut going in, and then also cut going out, the backlash in your drive will shift your cutter and widen the threads. With live tooling, you should cut at a slow speed, and if you are going to make more than one pass, you need make all the passes in the same direction to account for the backlash.


Keep up the good work! Threading parts is the only way to go. We thread just about everything. Threads make the best glue clamps in the world.

what are you using to feed the dremel the required thread pitch?

In his other post (post #4) he is showing what he is using to get the required thread pitch.

Placing a spring or some other positive load device, to keep pressure on the threaded rod joint. It will eliminate the thread backlash by loading everything in the same direction.

Great going!
The cutter is too long imo.
Cut it down to 1" ( exposed ) at the most .
You also do not need to make the threads on one pass.
Leave .010" for the final pass.
