Does anyone have a real number on the press fit of new axle tubes in a 12 bolt?
I’ve read that write up and believe there’s a lot of helpful info in it and apparently has worked. However, my local welding shop is owned and operated but a 30 year welding instructor that just so happens to be a car guy. I shared the thoughts with him about tig welding the tubes to the center. His thoughts and methods lead me in the direction I chose. The MG 298 rod offers a little better cleaning characteristic moving more of the junk in the casting out of the puddle then tig welding can offer. That’s why I chose to stick weld them.
Easy enough. Smoked plug welds out with plasma cutter then dressed holes with die grinder. Pushed housing stubs out on my press. I chopped the old tubes off and left an inch stick out of the housing because it makes it easier to handle on the press.How hard was it getting the old tubes out ?
Not at all hard to press. I actually built a jig on my narrowing jig to push the tubes. I can only do 1 side in my press. Then I put the housing on the I beam and use a porta power to push the other tube in. Works good.Thanks. Are the tubes a hard press fit in the housing ? Must need a huge press (tall) to get the new ones in ? Or can ya shrink fit them.
It’s been done with tig numerous times. Successfully I assume. The 289 rod is for stick welding. It was suggested because there are some characteristics in the flux that help flush away some of the garbage away from the puddle that shows up from the cast.So that's a stick (SMAW) type of welding you used. I wonder if its possible to TIG with the right filler.
