so, today was the day to measure and make sure the rear hardtail had been put on properly before I dive deeper into this build..
so I need your advice here people, please let me know if I'm doing this right, if so then I think all is straight and I can continue with putting rear fender on etc.
So, to check if the frame was lined up I tied a line on the stock frame, in different positions, and took measurements to the axle plates to check if it was the same.
Once I done that and was happy the measurements were equal, I cut the internal adjusters and welded external adjusters on.
here's the internal adjusters, as this was a Santee frame
As I can't really trust the rear axle being straight by pushing it all the way forward on the slots (as the slots might not be equal) I got the same line from the centre and turned the adjuster bolts to push the axle back to the point that the measurement was the same on both ends of the axle. Would this be a correct way of doing it?
Then I kept the adjuster bolts in the same place (as that way I knew the axle would be straight) and got the wheel on and checked for sprocket alignment, straight edge from rear to front and its straight.
by chance, when I welded the external axle adjusters, I welded it bang on in place, as with the axle straight (by using the line method) and the sprockets aligned, the measurement on the bolt adjuster is the same on both sides.
My welding skills are not great sometimes, so I couldnt really do a nice seem weld on the plate and adjuster, so had to fill and grind/file it down.. still a bit of filling to do.
So, the questions I have here are:
1. Measuring from the stock frame to the axle plates from and on different points - right way of checking its straight?
2. The whole taking line measurement to the axle and then leave adjuster in place, put wheel on and check sprockets, right way of doing it?
3. I've noticed that if I pull my front sprocket, the shaft has movement (it comes out a bit) is this alright? or is it all fked inside?
Thanks for the help!
once I have this alignment stuff done and dusted then I can crack on with all the other bits around that rear wheel!
