stack of coins

They are pretty welds and I think the brochures called them a "stack of coins".

For some reason the frames dont do a whole lot for me, (although the older Breezer model does), but boy, the American stems are one of the prettiest ever made I think.

EL, your frame is good looking too. Im partial to the older decals.

Anyone know what caused the huge improvement in Ti welds? The welds on my 88 Merlin are atrocious, but soon afterwards the welds become so pretty.
They probably figured out they needed to purge the inside of the tubes while welding ti.

but I'm surprised your merlin had crappy welds I've never seen a merlin with crappy welds.
are you sure its a merlin and if so it hasnt been re-welded?

worst welds I saw on ti were early titec's (I believe thats what they were called)

not to hijack but do you have a pic?

This thread made me pull the frame out. I have everything that I need to build it up (except the motivation). Soon though....

yes, the early Merlin welds are very different to the later ones.

that's frame no. 213 from mid 88. quite nice ones on the chain stay bridge but the other welds are all very irregular. looks like they were learning on the job







ps, nice American but why did they forget to smooth the welds?

Lunchtime, hot chick walked into the shop midway through, meteor strike in the parking lot, welder spilled hot coffee on his lap, someone spilled hot coffee on lap of hot chick, someone got picked up by the fuzz for not paying child support, maybe it was getting late in the day and they got tired, or in December of 1989 some guy walked into the shop wearing some really sick cycling clothing and they all ran like hell out of the shop.

As the saying goes, "Pick two"

was looking for a Koski but couldn't find one),

I think a Ritchey logic fork would also look cool on that bike. may be easier to find and would also work well.

I'm not sure what the rake is on those switchblade forks but it may work better with that logic fork just from a frame design standpoint.

at the malverns hills classic (for the UK readers)many, many years there was a stand with an MRC ti, fat chance yo eddy & american comp lite in purple. chatting to the dude on the stand turns out all 3 bikes were his. I was really impressed with the comp lite, just a solid looking build. nice rig :) look forward to seeing the built up pics.

Agreed, I've always thought the Control Tech stems were good. I'm still using one after 10 years. Similarly I've always loved the early-mid 90's Syncros stems for the appearance of the welds.

Before we get too far off topic, more welds...

As someone who welds on occaision, I'd venture a guess that they are using fat rod, and a fairly high temp, this would give that large dime, and keep it flat. Any pros out there have a thought on it?

I Don't Weld But...

...I watch them. As a CWI in the pipeline industry I guess I have some expertise...

If someone said "how where these welds made?" I would say SMAW with 1/8 or greater stick...not TIG. Probably slow to normal hand speed and good arc length control. Keep in mind that the pretty weld bead spacing does not lend itself to a good temp gradient, which is very important with aluminum. Does not mean you could not do the same with FCAW or GMAW, and it would certainly give you a cleaner weld with no chance of hydrogen embrittlement... But these welds reak of SMAW, which is a good process if applied correctly and much cheaper in application than other processes.

Note Aluminum stick welding is rare, but is done (usually DC).

Nope, They're TIGed

I've got a buddy that can lay down nice beads like that. Its a think of beauty!
He's not that consistant but I that could come with more practice.

I am no expert on the non-ferrous stuff so I stand corrected...but the fact remains that laying down a bead that long with wire and making it look pretty are one thing but it is another to maintain a good temperature gradient. There is appropriate bead overlap and there is pretty bead overlap.
