Well, I finally got some time to weld up the differential housing. What a lot of work. It took me all weekend. Here are the nicer welds. I am not going to show all the bad ones.
I still have trouble going around a tube. This was a great project to practice on because there are so many angles and hard to reach places. I had to buy a short back cap to get into some places.
I thought this was a cool picture of my welder. It is old, mechanical and worn out just like the operator. But it hung in there for me all weekend and didn’t miss a beat.
These old housings always weep a little around the axle tube. I decided at the last minute to TIG braze the tubes to the housing with silicon-bronze rod. It won’t really add much strength, but hopefully it will keep it from leaking. I tried both DC and AC settings. AC seemed to work the best. It looks pretty ugly before grinding.
But it ground down fairly well !
I decided not to weld the ends on until all the brackets were finished. Good thing because there was a large mismatch on one side and I had to reposition the ends for final weld. Both of my axle tubes are bent slightly. Rather than scrap the housing, I decided to just live with it. This means there is a mismatch where the end and tube come together. I made three passes and then a weaving pass at the end to smooth it out a little. I told my coworker that I probably created some sort of metallurgical taboo doing this but it is done !
Afterwards the alignment jigs still slid in the ends fairly easily with the alignment bar, so everything is straight and fine. I snooped around on the DSE site and found a housing where they put the brake hose tabs in this location. I just blindly copied it so I hope it doesn’t interfere with anything later.
I finally got to cut these housing stands off my welding table. It is great to have those out of the way.
I mounted the housing back on the cart and I will do just a little clean-up before taking it to the powder painter this week.
Next weekend is Goodguys, so I will be crawling all over the cars getting ideas for the next phase of the project. Probably won’t get much done this week but looking forward to some nice times at Goodguys !
