I think its your call, not all Stanley hub plats used square holes and square shoulder bolts.
Attached is a set of original 1907 hubs.
Look at the front hubs they have square holes and the rear have round.
If you have to remove the hubs the square shoulder bolts will come apart a lot easer.
You won’t be marking up the head of the bolts with vice grips.
I used round holes with a press fit raised shoulder on the bolt. I also used tapered rear axels and my front spindles I used tapered roller bearings.
According to the Kit Foster book page 465 There were only 100 Model R’s 20 HP cars built in 1909 To me that means it used the narrow frame early 20 HP engine with the first generation type H drive pumps. Gearing is listed as 51:57 with the 36X3.5 tires. 56 inch tread and 112 inch wheel base.
Rolly it should be 36" but in my experience it depends a lot on the make of the tyre. I use 895 x 105 Dunlop Chevron clinchers on my Model H and they are 35.5 inch o/d as they should be. We can also get (for a much lower price) Excelsiors (used to be Betco) of the same nominal size but they are only 34.5 inch o/d - only answer is to measure one on a car.
I just measured my Universal tires on my model R, size 36 X 3 1/2 and at 70 pounds per square inch air pressure they stand 36 3/4" tall. The tires still have new tread and I would suspect by the time the tires are all worn out that they will only stand about 36" tall.
Good morning Mike and the rest.
What I was trying to do was see how close I could come to a scaled measurement using AutoCAD. I can import a photo into AutoCAD and scale it to match a known measurement and then pick up the unknown dimensions.
This is assuming the photo is not out of proportion.
Any way I found a photo of a Model R on the net and tried it. Attached is what I got.
Tomorrow I will see a friend that has a Model R and hopefully he will know the dimension of the hub plate.
I’m betting it’s the 6.25 OD hub and BC of 4.930.
