Here's a few pix of the tapping machine I started building about 4 years ago. Behold, the DN2000- a converted shoe sewing machine. That's a pretty rigid column, mounted on a very substantial cast base, sitting on a pretty robust stand.

Close up of the tapping head, sitting above the vise. The vice slides left and right, as evidenced in this pic. There is a sacrificial piece of mdf under it- the only thing left for me to do is mill the bottom of the vise rails to lower it just enough to put the top of the mdf at exactly the same height as the top of the rails.

This pic shows the magnetic 'catch' suspending the tapping head assembly, and the next pic shows the assembly released from the catch.

Here's one tap prepared into a bushing that fits the head. I opted to modify a decent tap wrench for all the smaller sizes of tap, and that is what's shown mounted in all the previous pictures. With that removed, this and other bushings will fit directly into the head.

The vise slides left and right, but the whole table assembly it sits on slides in and out. There's enough range of motion that anything within the size of the vise opening can be oriented to be directly under the tap. If I'm tapping holes in long pieces, I'll mount a left/right oriented fence and just C-clamp the workpiece to it.

Nice! It looks like you could tap just about anything with that!

I certainly hope I can cover the bulk of my tapping needs with this thing. The column and table assembly is much stronger than needs to be for this application, but the extra weight will help to keep the machine from moving around when I crank the handle. I'm still open to other ideas to use the structure for. It's pretty quick and easy to remove the vertical bar and the table the vise sits on, so it could be back to the raw table and column in about two minutes. I was thinking it could make the basis for an edm machine also-

Like it.

Curious, any pictures of the DN2000 before it's rebirth?

I almost thought it was made from an old hardness tester!!!! Looks good. Now I don't feel bad about having projects that have been sitting around for four or five years.

That looks great , I like it when a peice of equipment is repurposed or rebuilt.If you want to try some taps that I got a couple years ago that work great.They are on sale at Sowa Tool $137.55 cdn. for set up to 1/2" nc #113-651.

No, no before pictures. The base had a few foot pedals, the table had a sort of turntable on it, about 4 inches in diameter and about 8 inches high. Coming down from the head was a tapered post that would fit into a shoe. That contained the needle and mechanisms to operate the sewing function. Up on the head was a few other levers.

When I got if from the junkyard, there was a nearly full spool of waxed cord inside- what is used to sew soles onto boots. The whole thing was caterpillar yellow. What remains of that you can see- I thought DN 2000 looked cool, so I left that alone.

It looks lovely, shame you didn't have a truckload of those castings, it looks like a commercially built machine so well done on that, I had an old tapping machine called a tap tru, it mistly did but was a pain in the arse to set up, loads of little adaptor and bits of spacer etc, I was sort of glad when it got stolen, bloody useless!
Keep it up

With all that height I would have had to make a motorized setup that could have been disengaged when not needed.

I thought DN2000 was the: Darryl ??? 2000, the 2000 being the year you acquired the machine, conceived of the idea, etc. Do you know the name of the manufacturer?
