Is it possible to tap a Lammy kickstart a centimetre away to stop it rubbing on an expansion by putting it in a vice and gently using a rubber mallet, or is it always necessary to apply heat to reshape it in all circumstances?
cheers.

It is better to put force on the lever with a piece of tube or stilsons rather than hitting, more controlled. Problem with heat it spoils the chrome but it is better.
Be careful using heat , I managed to soften mine , but I think the problem was I was using a blow lamp so the heat gradually built up , you might be ok if you was to use oxy acetylene because of how quick it would heat the metal up

That sounds familiar from O level metalworkDigDug wrote:It's how quick it cools that affects the property of ferrous metals and alloys.
I have reshaped one of mine using one of those yellow bottle blow torches (B&Q). Heated it to cherry red and used a lump hammer to do the 'adjustment'. I did that a year ago and it has been fine but it did affect the chrome. Not a problem in my case as needed to paint it matt black anyway. You won't get anywhere using a rubber mallet
Sorry for hijacking this thread , would it possible then to re harden my kickstart then , I pursume heating it up and quickly cooling it , it's a original sx200 one !

dom, technically yes, no problem. Regarding reshaping kickstarts, Ian at Taffspeed is a dab hand. It was a regular job on the dodgem

If you want a gentle bend? Maybe a conduit bender? If you have a mate that has one?Tractorman wrote:It is better to put force on the lever with a piece of tube or stilsons rather than hitting, more controlled. Problem with heat it spoils the chrome but it is better.
