Boxford handwheel handles

[Sam SpoonsParticipant @samspoons83065]

What is the thread of the handles on the Tailpiece hand wheel knob (and lead screw lever) on my 1961 CSB (school version model C)? All of what I have to hand is metric and these, not surprisingly, are imperial. I'm guessing 5/16" and coarse thread but UNC or Whitworth?

I either need to buy some suitable allen bolts or a die to cut threads on new handles

Thanks

They'll be BSW.

Cool, thanks that's what I thought

I always thought that CSB stood for College, School and Borstal! I get reprimanded if I spend too much time on mine. I have two, both 1958 models and both modified with a B type apron.

stay safe

Mine may well have been, it came from what was actually a very good school but it's reputation was often less than shining……
