Early Spring Engineering Update
07th March 2020


Having successfully completed the final riveting up of the rear drag box in the latter part of 2019, a daunting task with over 80 riveted joints, work has concentrated on moving forwards riveting up the various running plate support angles located along the frame.

All 12 frame datum buttons have now been installed and a start has been made at setting up the spring hanger brackets in readiness for riveting these into position. Carrying on from earlier in the previous year and with the arrival of the repair plates a start has been made at welding the leading horns guides ready for machining.

With the 60th anniversary approaching this summer the group aims to hopefully progress the new frames with the fitting of the new cylinder block, completion of the frame front end & valence plate work and painted up of the frames into the relevant top coats.

The rear of the frames in early March with the rear drag box completed & the majority of the various angle iron running plate supports riveted in along the length of the frame plates.
Some of the running plate angle irons now riveted in place.
 
Another view of the angle irons. These are some of the original parts salvaged from the original frames for reuse!
 
Re-bushed spring hanger brackets bolted up into position now that the work on the back of the datum buttons is finished. These will need to be correctly aligned reamed through and then riveted into place.
 
The front counterweight and sandboxes temporarily bolted up into position to help aid positioning the two front bits of re-used angle irons on the new frames making sure that everything will line up later on!

A couple of hours later the repair plate has now been fully welded on and ground back to a rough shape. The horn guide casting is now ready to be temporarily set in position on the frames and marked out, from the datum buttons, how much material needs to be machined from the running faces in order to obtain the necessary 15 thou running clearances. From here we can mill the working faces true and to size ready for final fitment.
 
The LHS driving horn guide casting tacked up and ready for the same treatment with the RHS next to it as an example of before and after.
