In article (3) I mentioned I'd mis-drilled a pair of holes - quite important as the relevant screws hold the motion thingummy assembly to the frames & has to be removable. The bodge is quite simple - cut some spare N/S from the fret and solder it in place...

only don't cut it free with a slitting disc...

However, having hand-cut two pieces the relevant sizes with a fret saw -

one was attached to the underside of the cylinder block, and

the other to the upper face of the frame spacer...

Having drilled the relevant holes it's time to fit the 14BA screws & nuts. Not so easy - the 'reinforcing' on the frame spacer iterferes with placing a VERY small nut! One answer would be to use a longer screw & wangle (another term for bodging!) the nut past the frame spacer. The bodgers route?

Use aforesaid carborundum disc to CAREFULLY remove material from the spacer (Left side),

unil the desired clearance is achieved.

Finally - job jobbed!
