An interesting machine Roland. The spindles look to have suffered the worst, suds damage? I hope the bearings are OK but dont look too difficult to replace. I will be interested to see how the cutters are attached, looks a bit crude at the moment.

Surface rust only. Bearings and slides are good. Tools go through the diametrical holes in the shafts and are retained by hex grub screws. It really doesn't need to be any more sophisticated.
Whitemetal is machined dry.

Sorry Martin it was my second post.

regards
Roland

Having stood and watched a Gypsy Major crankcase be line-bored I should have remembered that! :oops:

I've now stripped and rebuilt the machine. Despite its 60 years its in superb condition. It was beautifully made. Large dovetail bed with a large and long adjustable dovetail. The headstocks have adjustable taper rollers running in oil-baths. The gearbox handles auto or manual travel via worms and wheels with dog-clutched bevel gears. Apart from thorough cleaning and flushing out old claggy oil it simply needed a replacement shear-pin in one of the bevel gears. A pleasure to work on and once settled in position and levelled I have no doubt it will do good work.
I think tool-setting would have involved using a fork-ended micrometer. Anyone got one gathering dust please?

cheers
Roland
