Kim - I took these two pics earlier this morning 'just in case' - I think perhaps they are worth posting
Not wishing to labour a point but just in case you missed the significance of my previous post but this mod to the draw bar eliminates any need for spacers as the 'floating' nut takes care of any differences in draw bar length (within the limit of the thread length of course)
This is the draw bar made for the new mill - The top nut is held with one spanner the lower tightened to cinch up the tooling.
And this is the one fitted to the old Linley machine sometime in 1970. In fact I don't use a second spanner on the top nut on this machine just gripping across the belt to nip the pulley is sufficient to allow the tooling to be tightened. Neither drawbars have ever had to be removed.
A simple mod and one well worth investigating - or am I missing something here
Whatever, good luck with however you solve your problem and enjoy that new mill
