John Brighton of Steamline Sheffield:
"I have now used the Avonside Works Chassis jig on 4 problem chassis and three new builds and I have to say I am delighted, utterly delighted with the results and ease of use - it does everything it says on the tin!
I have seen many ideas come and go but I have not found anything, since the temperature controlled soldering iron 10 years ago, that will so revolutionise square, true, accurate chassis and rod building for anyone, good or bad, more than this piece of kit.
Avonside are to be congratulated. Everyone should have access to this even if it is only for the adjustable axle spacing pins!"
The pictures below show a Dave Bradwell K1 chassis under construction, where the hornblocks, hornguides and connecting rods are all perfectly aligned. Using the large square backplate ensures the chassis is both square and true.
