			The fine art of bumper straightening
		
 
			
				
					Does anyone have advice on repairing a very old and bent bumper? I tried to 'massage' the bumper on my 2a without too much joy, but want a much better outcome on the s1. Can heat be applied to make the metal more workable before taking to an anvil?? How much heat and with what?
 Thanks

					I found it easier to make a new one - trying to straighten a badly bent; heavy-gauge steel section, is fraught with difficulties. Heating it will probably only add to the problem by distorting it.
 
 If you want a copy of an article I wrote on how to make one; send me a PM,

					as above, much easier to buy or make a new one.

			Press
		
			
				
					Just use a standard 10 or 20 tone press, overlap your press plates and this sort of damage normally comes out pretty good.
