Henry, not sure what you mean? It's 40/50W and about 8/9 inches long?
I took the old screws out, got some new brass ones and cut lots of growves on the head of it with the Dremel cut off disc (leaving the cross so I could screw it in) then screwed it in halfway.
I filled the cross with solder and tinned the top, and realised I couldn't get the screwdriver in
I had to screw all 4 in with pliers then, which was as fun as it sounds
Then, with the heads tinned, I just got the iron, turned it up, fluxed, and it went like Swiss clockwork, top stuff
PS. Guess where my track rubber is, Steve
