The company was in Somercotes, may have moved. Europa specified stainless b
ut after a few cracked systems, they changed to mild steel without telling
Europa. Burnt through is 50 hours. Then they stopped altogether; probably t
heir insurers had a fit.=0AGraham=0A=0A=0A=0A=0A___________________________

ply supplied and =0A shaped it accordingly, except I have about a 5 m

which in essence thickens the ply by 8 =0A plies. So, now that its al

a release agent. So, that side is OK, but the first side I =0A have a
problem I am hoping I can use Redux and Flox to pack out both the =0A
gap between rod and ply, and also to create a flat bed for the gusset =0A
plates. I am wondering this would be considered an acceptable way to f
