Re-subframe Welding

[ClunkintheUK]

Following on the the Ignition Barrel replacement thread. The little scrotes also couldn't get through the chain (Almax series III, some damage to the cover, but the chain isn't even scratched) so instead they cut off one of the pillion pegs. Unfortunately being a Tiger 800 this is part of the main frame, and not separate bolt on pegs.

Any ideas on getting this fixed rather then replacing the whole frame (second hand ones are 500 quid, plus lord knows how many hours of labour to swap everything over.) Hopefully I can just get a sleeve around the cut tube, and wrapped around the main frame. Rest of the frame is tip top.

p.s. if someone tells me how, I can put up some photos.

Pics of damage?

How do you post pics?

Upload them to imageshack or similar, find the image link and post that here

Thanks.

That damage looks like they were just being malicious rather than a serious attempt to remove the chain. What little scrotes.

Is it steel? It looks like it, if yes then it is eminently repairable. If aluminium it can still be done but is not so straightforward.

I know where I'd take it in either case, if you need a name PM me.

It was locked through that space. Was definitely trying to steal it. As soon as I realised what had happened I re-locked it where you see the lock now.

I'm not sure the frame is steel tbh, think it might be alloy.

I've seen crash damage to the pillion peg part on a tiger before, who in their infinite wisdom thought it was a good idea to put the furthest part of a motorcycle out there to receive damage then make it part of the frame so not easily replaced?

That's one part of the design that I'm not at all keen on, I'd weld it myself tbh but wouldn't want to offer the service on someone else's bike.

Thought you might have knowledge sp1. Thanks. Yeah I would weld it, but I don't have the kit.... Or skill... Or any knowledge of welding of any kind apart from the odd bit of soldering.

[Sid Squid]

It is undoubtedly an alloy, but I rather doubt it's aluminium.

I've looked again at the pictures and is almost certainly steel as the wall of the tube is too thin to be aluminium.

Reckon you're right Sid, after a bit of searching on google, it does seem to suggest its steel.

At the risk of interrupting some seriously studious google fu I would suggest a magnet might clear up any confusion.

Where's the fun in that?

Personally I'd try arc welding it with a 3.2mm rod, if it blows to pieces, it was too thin :)

I can't see your pics (my browser), but just a thought.

Since it's not a major structural part, if there is any straight then you could possibly have a plug made to bridge the pieces and loctite and pin them. High strength Loctite (retainer/bearing fit) will not come apart if clean and the proper clearance is used (0.05mm typically diameter), and a through pin will give peace of mind rather than additional security.

The join could be hidden with an outer sleeve similarly fixed.

I would take this into an engineering firm who specialise in fabrication and welding, and get them to do it.
It'll be done right then. Yes, it may cost you £100 but they'll do a structurally sound job, and a neat one too.
I'm sure they'll also have the necessary tools/equipment to make sure the right materials are used for the job as well.

[yorkie_chris]

Not saying you're entirely wrong but fabrication and welding is a massive subject rather than something you specialise in.

Strip some stuff out of the way, get a bit of pipe, cut out damaged section, fair it into the frame and join them up.

Grinder and a MIG set.

It is a simple repair that any competent welder should be capable of. It is the sort of thing I used to give an apprentice a pack of cigs to do as a 10 minute foreigner. I wouldn't DIY it though. A bodge would look awful
