I picked up a drum brake front end for an '83 TT600 a little while back.

Intitally it looked to be okay, but upon disassembly, I've discovered that the chrome fork tubes have a slight bow in them.

If you roll the chrome tubes on a flat surface, there is about 3mm of bend in the overall length - not a huge amount, but it is causing binding of the forks when they are compressed without the springs in place.

Does anyone know of a place that can straighten these out?
And what sort of cost is associated with it?

Thanks
Peter

Garage press and a block of wood should do the trick

Knowing my luck, I'd probably squash the tube flat!

I was under the impression that it needed to be done with v-blocks and a dial gauge to make sure it was straight.

John is right it will straighten it but be careful. "V" blocks and dial indicator is the ideal way of doing it but not everyone has them and probably a over kill.

I would take it to a suspension specialist. I use SPMX in Seaford.

Or speak to Chad at Chad's Offroad Setups.  He's a good AMTRA friend and has been hassled by some of my requests over the years!

Each to there own
As you said it is only 3mm deviation
cut your self 3 vee blocks out of wood if you have a hole saw the same size as the fork tube even better drill a hole
in the wood and  cut it half set it up an the bench mark your high spot and give it a gentle press if it doesn't work
take it to a shop
nothing venture nothing gained
PS only use wood near fork tube
