Keep your eye on craigslist for a used TIG welder with High Frequency for aluminum. The non-square wave machines can be found for very little money. You'll be much happier with a quality used TIG than a new Home Depot MIG. I have both.

I have a three part question:
1. Does anybody have experience using 4643 filler rod instead of the usual 4043? I will be heat treating my frame and this filler rod supposedly contains small amounts of magnesium to help in the heat treating process. I guess 4043 is dependent upon dillution with ...

Thanks again for your input cryzsurfer. I know that "hit by the garbage truck feel". I have another question for you. I got a small bottle of straight helium from the welding supplier a few weeks back but had very poor results welding aluminum with it on DCEN. I'm wondering if they gave me balloon ...

I ended up purchasing a large bottle of 75% Argon/25% Helium for the TIG. This gas mix works much better on aluminum than straight argon. I even tried some DCEN with the gas and it worked. Very cool stuff.

Interesting idea on the Y connection. This setup won't damage the flowmeters on the tanks?

Hey Mike,
I am using an older sine wave transformer TIG to weld my aluminum frame. I'd like to get a pre-mixed bottle of argon/helium, but I'm unsure about the best ratio to use for increased penetraction on the downtube. Would you say 75%argon/25%helium would work well, or would a 50%/50% mix be ...

Ideally, you want to cut and machine on a harder (say T4 or T6 for the alloy 6061) temper of aluminum so that it doesn't "gum up" your cutting/machining tools. Bending should be performed after an annealing heat treatment (softening). Heat treatment back to T6 should be performed after welding on a ...

I would just like to formally thank Mike of TTM for sending me the pipe and silencer for my CR125 conversion. Your advice on heat treating procedure is also very much appreciated. The fact that you're willing to share this hard to find information with the other home builders out there is just ...

I am in the process of making the engine cradle for a CR125/500 conversion. Here are some pics of my homemade square tubing bender die that I made from 1/4" steel plate and a cheapo HF pipe bender. The tubing is 1" square 0.125" wall 6061-T6 aluminum. The bend shown was just a test in the T6 tube to ...

Beautiful job on your conversion, Juddy. I'm working on a Gen3 CR125/500 conversion, and also made a homemade square tube bending die for my cheapo HF pipe bender. I'll post pictures in a separate thread so I don't hijack yours. Nice Job!

I've been lurking on this board for a while and would like to formally introduce myself. I've been riding Honda dirt bikes for about 17 years now and have finally started my aluminum frame conversion. I'll be sharing photos in the AF section. Many thanks to the members on this forum for sharing ...
