Dude I hate to say it but this scares me. Frame work needs to be done with everything kept square and plumb. Usually done with an angle finder and lots of bracing. If something is out enough that it can be seen with the naked eye then the angles are way off. Harbor freight sells a cheap angle finder for less than $5 and it works. It will tell the angles way closer than the human eye can see.basementhardtail68 said:I wish I had more to report. I removed the stock cross member where the stamped backbone used to connect between the lower frame rails. I also made a new cross member that will be mounted a couple inches farther back than the stock one to allow more room for the motor.
When I was looking at the frame the other day I noticed that the down tube crooked to the left a little so i rigged up this redneck frame straightener and was able to move the down tube back into alignment with the rest of the bike. I spent a good amount of time looking at and measuring the frame when I was done tweaking it and I think it is fine.
Its nice to know that the old chevy venture has some use left in it even if it is only being used as a weight lol! Used the angle iron for a pry bar.
This is exactly what I'm talking about. What is there to keep the steer tube, backbone and the axle plates plumb and straight? there is always stress in a frame. As soon as its cut things move unless its braced.basementhardtail68 said:Not much progress but I thought I would share a pic. I have to modify the tunnel on the tank a bit to fit the new backbone. Also I have to put together some kind of steel work bench or motorcycle lift for further mock up. The motor is just sitting in the frame right now.
