I have broken the hollow bolt which retains the 1st stud gear on my Myford Super 7.

Can anyone advise me what sort of thread it is so that I can fabricate a replacement.

Thanks.

Peter

Peter,

The bolt you refer to is not hollow. It is a special with a head designed to engage in the slot in the quadrant to prevent rotation when tightening the nut. The shank is 1/4" diameter with a short length of 1/4" BSF thread. Not hard to make from a decent piece of steel eg from a large high tensile bolt

Alternatively try one of the suppliers of second-hand Myford spares on EBay or if all else fails a complete stud assembly is available from ."New" Myford.

The two change wheel studs on my Super 7 banjo do have a blind bore with a cross hole to allow use of an oil gun to deliver oil to the bearing surfaces,

Eric and Nick.

Thanks for your replies. By trial and error I found that a 2 BA oil nipple fitted perfectly. The 2nd change gear stud is also fitted with an oil nipple.

The bolt was probably used instead of a nipple as it locks the retaining lever for the second gear. Anyway I will contact Myford to see if they do spares.

Thanks again.
