Have you all had difficulty installing your pin drive wheels over the pins?
I had been meaning to order the Trigo alignment tool but when I went to order the other day, I found Trigo is closed until the end of the month. I had researched this issue and found Russ Thompson mentioned using a piece of tubing slid over the pins to persuade them into position. I found some folks would machine a taper on the pins and chamfer the edge of the pin holes in the wheels. I reached out to Mike Bray to find out how he had gone about solving the issue. I mentioned to Mike my intention of ordering the Trigo alignment tool... Mike was kind enough to email a sketch drawing to me with all the specs to make the tool. Mike has been a HUGE help not only with this issue but also how to correctly assemble the front suspension for pin drives and other discussions such as 37 degree flares with nicopp tubing...
I emailed Mike's drawing to a buddy of mine who has a CNC milling machine in his garage. I was about to order an aluminum disc from McMaster when my buddy called me and said he has a couple of old .750 wheel spacers and suggested we try to modify the wheel spacer before ordering the aluminum.
Mike suggested putting 2-3 3/16 threaded holes in the tool in case I had to "jack" the tool off the hub. My buddy cut the holes in the tool with a .010 tolerance...
To use the alignment tool, I get the pins finger tight and start the tool over the pins. I then use the butt end of a hammer and work the tool until it is fully seated on the hub. Tighten the pins down then use the 3/16 screws to jack the tool off the hub.
The wheels slide on with practically no effort. Prior to using the alignment tool, I couldn't get the wheels to seat on the hub with more than three pins installed. With all five pins installed the wheels wouldn't even start over the pins at all...
Another big thanks to Mike!!!
