Dear All.

Thanks for all of your very helpful comments that have given me the information I needed to progress.

I like very much the comments about 'good Enuf' which is a mantra that I practice, often !

If I get lucky, I may be able to not have to make the parts.

Regards Bob.

Hi again Alain Foote.

Sorry about the E,, it was overenthusiastic Typing.

I have to say that I am delighted with the responses to my query, as this is the first time I have ever been on a Forum even though I have taken the 'Workshop: Magazine for many years.

Thanks.

Bob.

Hi Brian Wood.

Thanks you for your response, good idea for the release spring.

Regards Bob.

Alaine.

Thank you very much for your reply.

I had done a drawing, in 'real time' full measurements and worked out an angle of 64 deg, but your actual piece from the m/c is better and makes it correct.

Perhaps you could comment on the rod that pulls the two pieces together, which I understand is 3/8" BSF. thread.

I looks to me that this size of rod will come very close to the pillar and I am looking to reduce it to 5/16 BSF (Found some in a drawer ! )

Regards Bob.

Hi, my name is Bob and I live in the West Wickham area.

I would like to ask for help for a part on a Meddings Dril Tru bench drill.

The machine has a serial number DBT 7742, apparently dated back to 1965 !

The part in question is the head clamp device that consists of two pieces of 1/1/4" round material, threaded on one half with 3/8" BSF, and these two halves are pulled together by a handle/rod that passes through them. Each half has an angle cut on it that will make contact with the pillar, once the head has been placed upon it. Turning the screwed rod locks the head.

I intend to make the parts but do not know the the angle to machine.

I have spoken to meddings, but they say that no drawing are available of this part.

Thanks.
