Haha, if you look at that last picture, I actually had a tube axle under it at one time in it's mockup state. I thought it looked a little too new for the early 50's ish look I am shooting for, so I sold it and decided to go with the I beam one.
Today I had 3 goals in mind to complete.
1) Make the plate that goes under the spring and bolt the spring in place.
2) Drill and tap the wishones to increase the thread size from 1/2 to 5/8 inch so I can use my angled spring perches to realign the spring to the wishbones.
3) Build the frame mounts to put the rear of the wishbones to the frame and get those welded on.
I actually only got the first two done. I found out we had the proper 3/8 fine thread tap, but didn't have a 37/64 drill bit that it takes, so I had to drive to a local steel supply house/industrial tool place to pick up one. It was a nice day, so I took my 27. It was filthy from sitting in the shop uncovered, so I just hosed it down and am going to have to give it a proper cleaning tomorrow.
While I was at the steel supplier I picked up some 3/8 flat plate to build the wishbone mounts out of. Luckily they had two nice small pieces in their drop area, so I was able to carry them home in the roadster.
Drilling the wishbones was a cinch, tapping threads was NOT a cinch. The ends of the wishbones are forged steel evidently, and it took about an hour each side to tap them. Even with lots of antiseize as cutting oil we had to tap a little bit, then stop and clean out the shavings. But they came out fine and the new angled perches screwed right in.
We mounted the front spring to the wishbones, and that is where Dan suggested we should put the Olds engine, transmission, and body onto the frame to see where it settles down to. I told him I already did the calculations, but he felt the only way to really dial the correct caster in was to load it, then set the caster. So we made temporary wishbone mounts and clamped them to the frame and bolted the wishbones to them, just so the wishbones will stay in place when the weight gets put on the frame.
At that point the 96 degree temp in the shop had gotten to us, so we wrapped it up until tomorrow. One change that I may make is not to use the S10 rear I was going to use. A good friend on another forum had given me an 8 incher out of his 65 Ranchero a while back, and I gave it to my Son Don when I sold him the 46 Tudor. But the S10 was just a little narrower than I would like, and the Ranchero rear is 3 inches wider at 57 inches WMS to WMS. My rear wheels have a dual Ford/Chevy pattern, so it will be no problem to switch. I asked Don, and he said he is probably going to have a 9 incher made up to the exact width he needs, when the time comes, so he gave the 8 incher back to me.
That is where we ended up tonight. Here is a picture of the lower spring plate I made up.
And here are the perches that I had to tap new threads into the wishbones for:
And here are all the parts bolted in place. This is not the final ride height , I figure it will settle down 3 inches or so when the engine and body are on.
