Zadar, shall I just get the rebound hole welded closed? Does it have to be perfectly smooth when its been welded up. I dont know anyone that handy with a welder!

Easier to braze it then polish it back smooth with fine wet and dry. I'm not sure that part is actually swept by seal anyway.

I think trying to find someone to braze it willl be more difficult than welding. lol

All you need is a gas torch and a rod?
If you've got a torch I can send you a bit of brazing wire.

Reason I would braze is it is easier to file back to smooth

Advantages of welding is heat is much more concentrated so you can probably get away without removing the seals.

I remeber doing brazing at school (many years ago). Would the molten brass not just spill into the tube (not necceseraly staying in the hole to be blocked)? Does that make sense?

No it should be viscous enough to fill the hole.

If you get stuck you can send them to me to TIG or braze, whatever zadar reckons is best way or your choice.

Im fine with tools, but do not own a gas torch or anything of the like.

Do these holes definately need filling, seems like alot of hassle. (its one of those, never done it before, so am a bit dubious).

YC, I could probably drive to you, and back in only a few hours. This might be better as I dont want to take up my friends garage for any longer than is needed with a bike hanging from the roof. lol. Wouldnt be for a good for weeks though, as he's out of the country untill March 21st.

Drive up on the bike?
you're better off leaving it for a while if you can't do stuff at home, it's freezing here and my drive's iced over anyway.

No, I'd strip the bike at my friends. Bring up the damping tubes. Let you braze them, and take them away and fit them myself.

I f you've done them before, I'd rather that than me **** them up.
