Thought I would add this in here too seeing as I posted up about my "lift" plans. The blocks have 1.5" real height at the bed ways. I had a 2" thick block billed to 1.70 so I would be left with an honest 1.5 between the lathe and the bed . The lift will kick the little 11" lathe into the 14" range. I am running a 12" banjo already, but I will have to get some 1" CRS cut into 4.5" lengths and build all new tool rests.
I am two days into it now and I have the work done on the headstock with all holes done and lined up. All that is left is to round the corners of the block and sand & paing the whole headstock assy.
Now on the tailstock, I had an issue with following the cad drawings at the local Voc. School that did the mill work. The shorted me .465 on the block! They milled the 2 blocks at the same time and then cut them to length and I gave them a 2" x 4" x 12" block so there should be about 2" left over. If so, I can easily have them cut a slice off the left over and I can then weld it to the block and once ground down you will never know it was cut wrong. All that is left after that slice is back on is to drill & tap the holes in the lift block itself to bolt the original cast plate solid to the new block and to hand make a new u-bolt for the cam lock.
