Threading jig

[Chuck C]

Does anyone have a bonnie klein threading jig? Anything comparable? Homemade? I'm pretty close to getting one for my JET mini.

Not a plan but it looks simple enough.

Wow that could almost be a "Kirby" jig!
BTW how much does a store bought one cost. That looks like quite a bit of work.

Craftsman micro torque wrench $26 off. Now $48. 9/16 to 9/18

I would consider something else.
These do not have lifetime warranty, Husky@HD,and HF ones do. I have both and the Husky is better in 1/2" drive size due to 250

Threading

I'm not familiar with Bonnie Klein's jig but I do use the Beall Wood Threader and have a review of it with photos and more on it's details at the link below if that might help.

the beall looks nice tom

do they say what the TPI(threads per inch) is anywhere?

[Tom Hintz]

I've not seen the TPI anywhere and never really thought about it since the jig and taps match and I'm not trying to match up to threads made by something else.
Just looked on their site and they do list the TPI for the various sizes they make,
1/2-8, 5/8-7, 3/4-6, 1-6.

HF dowel thread cutting kits - cheap alternative

I have a couple of these jigs.

They're non-power jigs. You hold the dowel and turn the wooden threading jig to both feed and cut the threads. It has a hole to guide the dowel straight, and a replaceable v- cutting edge and a threaded outfeed section to guide the right thread spacing. The tap has a straight feed section to guide it in straight, and you can buy an optional bottom hole tap if you make threads all the way to the bottom of the hole.

I read Tom Hintz's review of the Beall threader. Here's what I see as the differences:

You can buy a single size for as little as $20. If you buy the whole works including the bottom hole taps to get the same capability it will only cost $79 or so compared to $139 for the Beall kit but you don't get the nut templates ( I think you can whip up your own for just a few minutes work).

One advantage I see is that the HF jigs, being dedicated, you only have to adjust (maybe) once after replacing a worn-out cutter, whereas the Beall you have to adjust as Tom said, maybe three iterations each time you assemble the jig, die, bit and router. The HF jig is much simpler.

But the HF kits outside threaders are human-powered and possibly the cuts are not as clean. 10 RPM vs 20,000 RPM. Nonetheless, the feed rate is similar - you have to turn stock dowel by hand to feed it, just the cutting is done by the router in the Beall vs. your turning the threader to make the cutter cut the threads in the HF jig.

It's not really very hard work doing the cutting of the outside threads.

The inside-thread tap basically works the same way as the Beall, both are human-powered. Except instead of removing the guide to cut bottom hole threads you switch to a separate tap.

I don't have the cut pieces from each to compare side by side, but I can tell you I have at least satisfactory results - I've attach pictures of the quickie test pieces I did when I first got them. Actually they look pretty **** good.

Like the Beall, they come in 1/2, 3/4 and 1" sizes.

So I think the HF jigs are definately a contender if you are thinking you need some wood threading in your life.
