Title: pictures of a couple cranks I welded
Post by: rsss396 on May 12, 2014, 02:36:57 PM

Thought I would post a couple pics of some Hot Rod +4mm cranks I welded to increase the odds of no problems with the Tins giving us problems.
This was the first time I have welded the tins on a crank, I have always had them done. I made a fixture to hold the tins tight while welding and to provide a heat sink to not over heat the crank halves.
I also made a fixture for the tig gun to help make it easier to weld in a circle.

I think they came out pretty good for my first few cranks

Very well done, Dave. I know from personal experience that it is not terribly easy to tig and it turn out  nice and uniform. Looks good.

Those look pretty good Dave. I wish mine would have gotten the treatment before it grenaded one afternoon.

thanks, it would look better if you did not have to stop and let it cool some before moving to another area of the crank to weld, then the last weld when you connect the beads will sometimes pop on you from expanded gases in the tins trying to escape.

Sending out to get re-balanced? Think there is enough runout in balance to do so?

Awesome looking tig welds, Wish I would learn how to MIG atleast

That looks good. Good job

No rebalance needed I only used about 1/10 of a gram per inch of weld. If that is done evenly then nothing has changed now obviously it's not perfectly even but since the amount is so small it will not make any difference.

you have to remember that nether Honda or HotRod dynamically balances there cranks.

Looks good Dave.

They look great.  Every now and then I get a bead that pretty, but not enough constancy to go all the way around a crank.  Curves are tough to keep the correct angle.

sweet. what machine you using ?  i was thinking of a new miller dynasty but them buggers are expensive for just occasional home use. but i like to do most of the work myself if i can so maybe it would be worth it

Thanks guys. I use a Lincoln invertec tig. The Miller dynasty are great machine from what I hear I got this machine almost 10 years ago and it's been flawless

Do you have pictures of these?

What about the other side of the tins, the inner side, is there a need to weld there as well?
