DTI accessory threads – Mercer – Verdict etc.

[Rik ShawParticipant @rikshaw]

I've never taken much notice of the bits and pieces in my DTI boxes – if they do the job then that's OK for me. Today though I had a need to modify a dovetail clamp to suit a job that I'm doing.

If you look at the thread on the LH side of the clamp I want to make a knurled knob to fit the thread. Easy I thought until I checked the thread. It is 7.2mm diameter and my metric thread gauge indicates a pitch of .065mm.

I have a good collection of taps, some wierd but nothing that will do this job.

Hi Rik, do you mean 0.65mm pitch, which makes it very close to 9/32" x 40 tpi ME.

Hi there, Rik,

I don't know if it's in the latest edition but the MSC catalogue used to have a couple of pages devoted to screw-on accessories for DTIs. There were two series, one with a metric thread, the other with a USA inch-based thread. (The listing says what the threads are. )

I haven't checked lately but you might find their on-line catalogue still lists that information.

Best regards,

Swarf, Mostly!
