I have Knocked all the brass tappet guides out of my welded up Nippy Block ready to go on the works surface grinder.
The block has been repaired by Laser welding.
All the valve seats have been rebuilt ready for re cutting and a hole into the valve chest from one cylinder has been welded up ready to be re bored.
I might see if the bores can be done on one of the big CNC mills with a flycutter.
This work would not be worthwhile on a normal block but genuine Austin Sports parts are worth repairing.
