Tuesday a little progress on the Nippy special rebuild. Fitted the offside front backplate and Hydrate 80 (Bilt Hamber) on ends of the 4 X 5/16 BSF bolts, king pin cotter - both ends and radius arm nut + touch of etch primer when dry.
The full process was:- 4 bolts cut to size and ends rounded off so flush and no thread protrudes from stub axle and therefore can't go rusty and damage the axle threads if needing to be taken out; shot blast bolts to remove any old paint; thoroughly cleaned and treated with Bilt Hamber hydrate 80; quick spray of heads and new tab washers (with tabs slightly bent up ready for final locking) with etch primer; next day spray 2 coats gloss black engine paint.
Today - started fit of nearside front backplate. 2 bolts had to be ground slightly shorter (one thread too long) and rounded off; Treated Hydrate 80, etch primer then 2 spray coats engine paint. Ran 5/16 tapered tap down the 4 threaded stub axle holes to clean out the KBS Coatings black paint where it had run into the hole ends at the back of the stubs (the paint is very strong and would probably have damaged the bolt thread end).
I am beginning to wonder if it is going to be ready for the centenary!!!! But I never ever want to do any more rebuild on any of it.
