I was just playing around tonight and cut out a new practice block. Drilled all 3 holes at zero cant just to see how close my drill press was drilling the holes with "The Block". The car pulled slightly to the right with the weight centered over the back axle. About a 1/2" over 3'. I can bend an axle and easily align it, I know all that. I was just messing around with the weight. 2 oz. of flat plates stacked on top of each other. I kept moving the weight to the right until it was even with the right edge. This made the car run perfectly straight. What does that tell me? Remember, zero cant on front and rears. Does that mean that the left rear wheel is out? Why does moving the weight from left to right have any effect on alignment? BTW, when the car pulls to the right (RF is dominant wheel), the rear wheels don't ever move left of where they start. It just seems to gradually go to the right. I was just curious if anyone ever drilled a block that ran perfectly straight without some adjustment. Seems like you would never get the alignment PERFECT without some adjustment. At least not with an ordinary drill press. I rotated some of the axles around to see if that fixed it. It didn't change much. The axles are obviously pretty straight. All the wheels are staying out to the axle heads. This is MUCH closer than I have ever been before without adjustment. I guess if the dominant front axle (RF) was slightly backwards, this would cause it to pull to the right. if the RR (Dominant side) was slightly backwards this would keep the wheel on the axle head. If I am thinking correctly, I turn the block over and around to drill the left rear which would in turn make that axle be oriented the same. Am I thinking straight here? Would this not make that axle slightly back as well, which would also keep that axle running to the nail head? Well, I think I may have answered my own question. I guess I'm just looking for confirmation. What do you think? Thanks in advance.
