JB Weld lugs
 
Anyone try this?
Just get any non lugged frame, jb weld on some lugs and file it down till it looks good.
It occurred to me while drunk, and there's no way I'll do it to my frame, but I'm sure someone else will..

j3ffr3y 07-30-09 03:49 PM

it would still be a welded frame

do you know how a [real] lugged steel frame is constructed?

jim-bob 07-30-09 03:52 PM

I don't see a downside to this.

JB Weld!?

We already knew that.

Oh I understand perfectly how real lugs work...
But **** it, if you took any maxway frame, sanded it down, gave it some lovely JB weld lugs and then repainted it all nice no one would know.

I've got an old Free Spirit frame that I was thinking about using JB Weld on to make it look like it was actually welded (currently appears that only friction is holding the tubes together). I never even thought about making it lugged! :lol:

WELL like ya say folks! do what you want with your own life!

clasher 07-30-09 05:14 PM

Just make the entire lugs out of JB weld! Or bondo! Then you could "lug" an aluminum frame too! That'd be bad-ass. Post pics, plz.

REMspeedwagon 07-30-09 08:30 PM

wat.

Seggybop 07-30-09 11:43 PM

I thought this thread was going to be about actually making an epoxied-lugged frame like the ones that were common before cheap aluminum welding was available

but it turned out to be about using a high-strength structural repair compound to paste on decorations =/

There are some older bikes out there with faux lugs. I think they were just stamped metal fixed into place.

JohnDThompson 07-31-09 11:51 AM

Why not just paint them on? Then everybody can "ooh" and "aah" about the meticulous lug thinning.

JB weld would work great, for a while. to make epoxy bonding work long-term the tolerances must be exact and the epoxy mix must be exact down to the last molecule. that won't happen in a typical garage.

Claud Butler was one of these makes, maybe even the only, except that it actually had a purpose.

"In the late thirties Claud Butler began to experiment with bronze-welded construction without the use of the usual proprietary lug castings. This was a technique used by continental frame builders that had been taken up by one or two English marques. It was a construction method that would become a feature of the Claud Butler range. Lugless ‘welded’ frames were often regarded as an inferior alternative to lugged ‘brazed’ frames, as the lugless frames demanded less labour. By 1948 the ‘Avant Coureur’, a model using 'Bilaminated' construction had been introduced. This consisted of decorative sleeves pressed from flat-sheet steel being applied in place of lugs, and necessitated a mixture of bronze-welding and capillary-brazing techniques to produce distinctive and ornate 'faux-lug' designs. Not only was this construction method aesthetically pleasing, it was also superior in strength to the established methods of joining lightweight steel tubing. It also saved labour and avoided the necessity for lug castings which were sometimes difficult to obtain during a time when British industry was forced to concentrate on export trade."

How are you going to get the tubes into the lugs? The old frame is already welded up. Maybe some more drinking will help you figure it out.

cut them in half and assemble over the tubing?

I think he's saying that you would ploop a bunch of jb weld onto the frame, then file and sand to make it look like lugs. I mean, it's a dumb idea, but you're taking it too far thinking he meant to make actual lugs...

Either way, I want pictures!

You're both waaaay overthinking this. He said the idea came to him while he was drunk.

wearyourtruth 08-01-09 12:24 PM

i love how no one really knows what the OP is talking about... (myself included)

robertv 08-01-09 04:27 PM

Was I that confusing?

FAKE lugs on an already built and welded frame. You put some JB weld around the seams, shape it before it hardens, then file it down to perfection. No added function, no loss in strength, and obviously the JB weld IS NOT HOLDING THE DAMN THING TOGETHER. This was a drunk idea, not a completely braindead one.
