I am too tired to properly cite the man right now. I will find his essay and cite it properly. I have dumped bicycles and motorcycles over the decades since I began riding, and bicycle crashes have always caused much worse damage. Leathers work great, but are too hot even for MC riding sometimes. Until I do, you are welcome to ride Elmer's glue fastened pasta frames-one less snide puke would not be missed.

@iq166 it has been proven that welded 4130 frames are weaker than silver brazed frames. There, now we've both made claims without any supporting evidence.

@frightrover hey man, sometimes low-tech is the best tech
-
How are the chain stay tubes tapered?
-
It has been determined by rigorous testing, that 4130 is weakened by brazing due to the brazing alloy entering grain boundaries and 'lifting' or separating the grains of the base metal. Gas welding or TIG is superior in this alloy.

Terrabladder= brazing is so strong that just a silver contact
braze in between a channeled groove and carbide tip
then brazed fully with brass is strong enough to make stone
cutting chisels that will last a lifetime if treated and used
properly....They'll take more of a beating than any bike frame ever will due to nature of it being a tool...
-
Cool enough but an explanation would have been worth the bother, a look at the finished item in full glare too.
-
Welding would be great for a thicker wall ... but most people don't pre and post heat properly ... I'd prefer the lugs ... they take a beating ...
-
I would think that a nice tig weld would be the way to go, you can adjust the heat and penetration
This comment has received too many negative votes show
thats about as low tech as it gets man,junk job.

yOU ARE UNPOLITE, ON A BICYCLE BRASING STUDING M.I.T FILLET BRASE WITH SIF NICKEL SILVER IS STRONGER THAN TIG. I built 1000 frames no one cracks is full of carbon an alu who are cracked. I wrote a book How to cook a bicycle in your kitchen
