Default From the House of Baaaad Brakes

I broke out the TIG welder again today, and it went well. I was frustrated with the welder and I couldn’t seem to get it to pulse as needed.

I finally shut off the pulse and used the pedal and suddenly I was happy again.

Anyhow, I am customizing a bike for some rat rod club and made these funky brake arms up from two sets and some chain.

That's a neat looking setup!

A few are motorized, but it’s a bicycle club.

It took me a bit to realize how you did it cause bikes are unfamiliar to me. I see the weld is well hidden or you did fusion without a filler rod. I have done that on some delicate stuff and I was surprised how well it worked.
With Tig, I'm at that 'uncertain' level of experience, where you have good days and some days not so.

I Changed the tungsten six times for four welds, buddy. It seems to be drawn magnetically to the puddle.

First I bobbed off a left and right brake arm. I stacked identical unbobbed arms on top them. I took an unplated flat washer and ground it to fit inside the joint.

Then I could just blast right through the crack into that thick flat washer and not have to worry about burning back at the edges. This made for a very strong assembly.

I marked the hidden washer with an arrow because it’s not too obvious what’s going on in this photo. There was no welding in this area. That’s a really awful photo because the welded assembly sitting in a can of washers and springs.

I used some regular filler rod & I ground the welds down and burnished them so the parts would look nice. That’s why the structural washer was important.

I did take a photograph that shows two welds after they were dressed off.

Lookin' good, Cadd--I like the incorporation of the bicycle chain.

They’re mostly into these rusty paint jobs that look like you just pulled something out of a junk pile.
