For lack of anything more exciting, I am making slow (but steady) progress on the bumper. I bought a 1.5" dimple die from TEMCo Industrial rated for 3/16". After much deliberation I knew it would be difficult to make this happen the way I wanted to because of the fact that the rear skin is already bent and there's not much room to get as close to perfect contact as possible between the press and the die. An assorted stack of round press plates seems to do the trick. It's not for everyone, but I love the dimple die look and I want to carry it over from my front bumper in small sections all the way through to the rear. Now I need to figure out if I really want to do it to the bumper wings as well or just leave them unbothered.

Thoughts?.... Lay into me if you think I should just let natural selection take care of me for my poor decision making...happy roasting!

It will look good and one of a kind. I wonder at what speed it will start to whistle.
That’s what I think every time I see a guy with gauges.

Zero fabricating here. Bolt on and go. Ordered a black crossbar to replace the raw finish one. Not bad considering my welder is giving me fits currently.

Found a home for the old 33s from the Taco. Put brakes on the trailer so got hubs with 6 on 5.5 bolt pattern. Left suspension alone so just mounted the fenders higher to clear at full stuff. Bend the ATP on my Swag press brake and then welded the skirt pieces on. I still suck at ally TIG.

Is there a direct correlation to shaft diameter and required spline interface, to say, if an output shaft is 1" in diameter must an adapter for said shaft sit minimum of 1" down/over the shaft for max strength. Does the diameter of a shaft include the spline height or is just the center portion before the splines used to determine strength? I understand metal composition/type, heat treatment, and application play their role but talking specifically about transmission output shafts and axle shafts?

I don’t know the answer but I’d assume you’d want the engagement to be at least the same as the minor diameter of the shaft.

The scientific answer would be it depends...lol.
Torque applied to that specific engagement point would determine the amount of spline engagement.

Customer brought a car in for unrelated work, sold him on a new roof since this one is obviously fucked. Pulled the cage off the car and started to see some sketchy shit. Tons of ugly welds and massive voids. Completely out of square, zero penetration on some of them. New cage is on order and my welder should have it done by the weekend.

Just some practice that I felt pretty decent about. Hoping I can dial it in by summer and take over our production welding. Little Lincoln 140.
Consistenty is the hardest thing to nail down. I have been trying to stay slow when I start a bead and only speed up once the material heats up.
Nice welds though

This is what I was asking for specifically, running a Aristo A340E from behind 2jzgte TT VVTi (290hp stock but bumping said up to 400ish) mated to my Atlas 4 speed with 10.34. I was originally going to was trying to run said without a 3/4" spacer that I now need to run because I planned to shorten the tone ring on the back of the 2jz A340E, this plan changed and now running the tone ring without shortening. The issues is I already cut the output shaft down... with the tone ring I have 3/4" of usable shaft, now if I was running the standard A340 found behind the 5vzfe, the Atlas spud shaft only uses 15/16" of the output shaft (3/16" more than I currently have with the 2jz A340). The out shaft for both is about 1 1/16" minor diameter and 1 3/16" with spline height. A buddies father told me that back in the day when he worked as a machinist that the rule of thumb was you need to engage the shaft diameter as a minimum for full strength, but he also said alloys are much stronger then when he did this shit, so I mite be fine. Now the 5vz A340 output shaft is a hollow shaft where as the 2jz A340 is solid (which is stronger when handling torsional loads). Now I do have another 2jz transmission I can pull the output shaft from and get the full 1 7/32" of usable depth form the Atlas adapter but was trying to save the transmission as a complete spare...

The amount of spline engagement isnt an issue of the shaft strength, rather the ability of the splines to transmit power without deformation or catastrophic failure.
3/16" doesn't seem like a big deal in this case. I would run it, unless you regularly beat the tar out of your vehicle.

I built a thing, so I can make spindles for my truck.

And used it for some TIG weld process experiments: less heat and slower travel and I get more 'Gram worthy welds.

I think most of the time I'm going too fast and getting the gas pool off the hot puddle before it's fully frozen, and possibly getting oxidization in through the back of the joint.
