Re: Rail filing jigs - 3D printed

No worse than using a hardened steel jig surely Martin? The hardened steel jigs are a very fine way of blunting a file! I have a couple of files I dedicate to them for this reason (and because they go blunt, using them becomes progressively harder). ... Or perhaps rather better, as the file may blu...

Re: Swanage (again)

Harking back to the discussion on turntable outriggers, I came across these pictures in Modelling Railways Illustrated of September 1993. They show how outriggers were used to extend turntables by running the tender up the outrigger. It must have left the turntable badly out of balance and hard wor...

There's also the 'rolling it on the carpet' technique as taught by, I think, Malcolm Mitchel for boilers. The circa 3/16" rod you'd be using might be a bit bendy, though. This mimics a technique for forming sheet involving pressing a former into rubber. Essential the same as my, on your thigh ...

It just seemed that using improvised bending bars is so quick and easy...... My point was not that you shouldn't using something to apply an approximate bend, just that, as you have an available profile it didn't need to be anything like exact. To bend it in situ you'd have to put stringers on edge...

Re: Bend it, bend it ..... !!

While its nice if you have the expertise to exactly match the curve on something to the place it is going to fit, it isn't actually necessary much of the time where there is a profile piece for the metal sheet to follow. Profile pieces you have lots of. Roughly (but gently) pre curving the metal par...

Re: LNWR Problem 2-2-2 CSBs

Additionally, shaft power = constant x rpm x torque, so there is benefit in keeping the shaft in the high rpm part of the drive drain, so as to reduce the torque reaction between the loco and tender. As Crepello, and theory, says you should not reduce the shaft speed until it gets to the loco end. ...
