Good turning and be safe

>Stan,

While I don't own one, I attended a one day demo and watched Bonnie demo cutting threads.

1) The cutter is held in the spindle with a collet.

2) The work is held in the X/Y axis device and turning what looks like an indexing device actually rotates and moved the work laterally. It has a threaded shaft (16 tpi, I believe) that sets the pitch of your threads,thus they will always be 16 tpi.

3) Depth of cut feeding is done on the "Y" axis

It works very well and is quite simple to use, once you understand the principle.

If you have any more questions, feel free to ask.

Aloha,

Doug

I haven't seen the Klein threading attachment demonstrated but have seen the Baxter threading jig demonstrated several times. It's quite simple to use. You can see it at www.bestwoodtools.com

I went there and looked and could not find it. What is it listed under?

>I've watched Bonnie demo this as well, and it's a very easy process. The learning curve looks quite short. I haven't purchased it yet, but it's on my wish list. I'd recommend it by far over hand chasing if you want something quick and very accurate. Hand chasing has a huge learning curve in comparison.

I don't see it on their site either. I talked to them about this tool just a few months ago. Their website has been completely revamped. I wonder if somehow it got left off or if the website is incomplete. I'll have to give them a call and find out.

>I own one and it works like a charm. I was fortunate enough to get it directly from here and have her demonstrate it. I would contact her on her site [link below] and ask her how much a combo deal would be with the jig and her threading video that she now has availabe in DVD. Between the both of those you'll be all set. You can tell her Ron from Israel sent you and it may help, I hope it doesn't hurt. =o)

>I recently bought the Klein threading jig and have had trouble getting the fit right on the lidded box between the lid and the box body. Assuming the lid is sized and threaded first (the female threads), my understanding is that the tenon to be threaded needs to be a bit larger than the lid's for the threads to properly interlock. Am I correct in this and if so, how much larger? I once saw Bonnie's video and the figure of 1/16" seems to come to mind.

Doug Leite

>Charles,

In metal machining, the double depth for 16 tpi is .082, which results in a rather sharp thread. If memory serves me right, Bonnie used a figure of .045 (3/64") which allows a much larger flat. Your calculations must allow "air space" so that any bind in eliminated, and careful measurement is necessary.

Example;

If you cut the internal thread first, and lets say that your box's male thread is to be 2" exactly,take 2.000-.045+(.010 for clearance) and turn the inside to 1.965 dia. Now, when you thread the male piece thats 2" .045 deep, there will be .010 clearance in the threads to assure smooth operation. You only need to be careful with the female threads and cut the male side until you are happy with the fit. If done right, that should be at the .045 mark.

I hope that I made this understandable.

Aloha,

Doug

Al Crandall

>I took a hard look at the picture in the Packard catalog and built two from plywood. One is fixed at 8 tpi and I gave it to my turning club for a raffle to help raise funds. The other one I kept, and it can be adapted for 6 tpi, 8 tpi, or 10 tpi. I felt that 16 tpi was just a bit fine for some woods which might move a lot. Sliding plywood dovetails made the unit work pretty slick. The cutter is a 60 degree double angle cutter from Enco, and the holder for it was shop made from wood also. The learning curve is very shallow once you understand the relationship of male threads to female.

Re: Klein Threading Jig ?

RonZ

>Doug is right and depending on the wood, it's a good habit to strengthen the area before and after with thin CA glue. Also she recommended grinding down the end of the cutter flat a bit so it will allow you futher in on the threading.

Gee Al your up early.

Al and I belong to the same club. He bruoght his threading machine to my house and to the club and it works every bit as good as the store bought expensive ones do.

Charles Bjorgen

>Doug and Ron -- Thanks for your info. I recall Bonnie's recommendations to use CA to strengthen the thread areas and will use that. I'll have to check out her video from my club library again and go through her process again. I note also that Sorby has a caliper gauge that allows for making these measurements but wonder if that is only useful for hand thread chasing?

>That is only for hand chasing threads.

Klein Jig, Some help...

Loose Tenon

>I have the threading jig and use it a lot. There are, however, some things to keep in mind:

The sides of the female opening must be straight and a clearance must be cut at the opening of the lid, a 1/16" wide and deep, then champfered to 45 degrees.

To cut the male thread tenon add 3/64" to the internal measurment of the female thread and cut a small sizing tenon on the base to reflect this.

If it's slighly oversized that's o.k. as you may get movement in the base after hollowing.

Then base tenon can be adjusted for size and lenghthened to 3/16" or slightly longer. This is then champfered to 45 degrees on the end.

As others have stated, (DON'T touch the teeth), grind the end of the thread cutter so that you can cut closer to the top of the lid and the shoulder of the base without fouling the work.

In Richard Raffan's Box Book he cut's a clearance at the end of the male tenon, I do the same with a home made tool from a masonary tool.

I haven't use Super Glue to strenghthen the threads, but on softer wood I'll make two passes.

I use glue blocks and don't remove the lid until I'm happy with the thread fit. Bonnie doesn't recommend this in her literature, but I remove surplus material from the lid in an effort to get a grain match. When I get to within a 1/2 " or 5/8" I remove the lid and continue to shape the box. When complete the remaining wood to get a grain match can be removed from the shoulder on the base. Note: there will be movement that occurs during sanding so keep an eye on the grain match as you proceed.

Practice on some scrap wood to start and whatever internal shape you have on the base, be sure and leave a straight portion at the opening so you can jame fit the base for final finishing.

I hope I've helped and not confused.
