Thread: My new threading Jig

Thanks for showing this Neil, great use of the wood lathe here. Your setup for this has given me a couple of ideas, especially how the slide table is used. How far is the travel x & y on the table?

It is the KT140 with 100x230 movement, see McJING Tools Online

Thanks Neil

That is a nice looking set up.

Well done Neil I look forward to seeing this in action ,as we know the proof is in the pudding hehe ! cheers ~ John

My old man did a similar thing once - he used a router in his 'concept' Rose engine to cut threads on the hundreds of salt & pepper shakers he made - I still have the 2-bladed router bit shaped like your cutter from it.

How do you rate the build of the KT140 Neil? - I've often thought it would be a handy item at times

So far so good, it really is a big solid piece of equipment at ~20kgs, certainly a lot better than the two-way compound slide vice I have on the drill table. I have plans for may other uses for it.

Brilliant. I saw Bonnie Klein's jig at Turnfest this year but I guess yours is a bit cheaper. Well done

Check out this item on Ebay- Item 290722228259. He will make them to fit any size post and our 30x10 system. A mate got one and he says its simple and well worth the price.

Simple and great idea so easy to reverse to do internal and external parts just by use of the cross slide.

Although now you have a metal lathe why didn't you just use that

Had to make some mods after taking it for a test run on the weekend. I did the rod thread on the metal lathe, but used a tap for the female as it was easier. Unfortunately I made the rod whitworth, the tap was UNC . I made a few mods to make the threads match and thought with the brass thread guides would be Ok. They did work, but there was just too much slop in the thread and they had to be very tight.

So John helped me install a bearing at either end, to support the rod, the thread was then only there to provide cutting guide. We slimmed the rod down to 24mm to give a good flat to seat the nearing and fit the 24mm bearing. Unfortunately I read the size wrong, they are 25 not 24mm ID, so then had to turn bronze shims to fit

The bearings are housed half into the Al block, half in a rebated housing made from some Al plate.

All good now, solid as a rock

Metal lathe is not mobile like woodfast, nor swing size of JET.

We slimed the rod down to 24mm

Looks good Neil. Can't wait to see some product.
Where did you get your cutter? I tried to find one a while back and did no good.

Cheers John
