Cracking frame mate...[Pace Content]

7005 alloy frames do not require heat treat if welded correctly. That is why Easton devoloped the alloy.

I always thought it was t'other way round and it was 6000 series that didn't need heat treating as it air hardens which is why all the small U.S. builders used it and 7000 series did need post welding heat treatment hence it's use in the Far Eastern factories.? :?

6000 series always requires heat treating,7000 doesn't.The main reason US builders use 6000 and Far eastern factories use 7000 is that they are each more readily available in those home markets hence a Zaskar LE was 6061 and a Avalanche was 7005.

Well there you go.

You learn something new every day.

Right. 6061 takes a few seconds or minutes only to anneal, 7005 takes much longer. The welding window is wide open with 7005. Easton developed the alloy for thier baseball bats. The ends could be quickly welded and cooled before any harm to the hardness. Easton does recommend a stress relieve on bike frames though, but usually the Powdercoat oven bake takes care of that. That is why the motherload of Asian frames are painted.

Urgh....

Pinky's got a crack in the frame up by the seat tube/seat post interface...

Nnnnnooooooooooooooooooooooooooooooooo..... :shock: :cry:

Glad it's on the road to repair tho..

Pace used 5356 or 5556 TIG rods to build the frames

 

[Radar]

methinks explosif fan just won the "Pace anorak of the week" award for that little gem.

How the flip do you know that?


If only there was a Pace pub quiz ....

I'm a bit scared to ask Kevin just in case he decides to twat me over the head with Pinky causing it to crack again...

Was going to organise a respray with my last guy, but found out he passed away just before Christmas in a cycling accident...

RIP Ross Bee...you were the man!!!!

Search continues for a decent re-sprayer...watch this space

I know..it really took me by surprise...it was only a couple of years since I had pinky done, thought, I'll take it back to Ross as he did such a great job last time...When I first met him we chatted for like an hour about bikes and stuff before he even got around to asking me what colour I wanted on my bike, such a genuinely nice person....he'll be sadly missed....
