Tapping straight

[Peter Ellis 5Participant @peterellis5]

WIP

Made to take the Pillar Tool accessories.

This is my tapping 'machine' made from mostly spare material and a ground column.

Used a few of the details from Geo Thomas design,

Sorry I Can't rotate the image !

Richard B's "machine" is not unlike the one that I made from a piece of box section, a spare small drill chuck and a redundant stand for a pistol drill.

The main thing is that the spindle, column and base are all perpendicular to each other in both planes.

I'll try to post a picture in my albums

Bruno Mueller has done one without castings.

Thank you

Unfortunately, Herr Mueller has described what he built in German – which is a closed book to me.

The photographs showed what looked like castings to me!

With best wishes and thanks again.

The pictures show a lot of work making stock look like castings. Which is an odd thing to do on a tool.

What's so odd about that?

Posted a picture in anew album, but cannot rotate it!

The original opens up correctly oriented, but the one in the album is 90 degrees out.

Sorry, you can see how rough it is, but still does what is required.

Here's my approach to this issue. :-

I have a tap-holder (jacobs chuck) and two different sized die-holders on 1/2" shanks, and A pair of MT adapters for my lathe tailstock and mill spindle – on the drill-press I just use the chuck jaws. This set-up will deal comfortably with thread-sizes ranging from 12 BA to 3/8", and can be used to start larger threads which can then be finished by hand. If a non-cylindrical thread's position and alignment are critical, I'll usually set it up in the milling vice to ensure accuracy.

Use in lathe tailstock (the die holder is hollow) :-

Mill spindle :-

Drill-press :-

I too have suffered from the dread 'image rotation' issue, my apologies.
