Looks good, like John said though, I also used Oldham couplings for mine. |
| John Stevenson:
You can also fit bearings into this type of table as well, needle rollers and needle thrust, makes them a lot smoother. One on the left is original, centre one has had the eccentric shortened down to get two thrusts in and bored for the needle rollers. Far right is finished and assembles with the oldham coupling half doubling up as lock nut and adjuster. finished and tested. John S. |

John S It looks like you have turned about 8mm off the rear of the eccentric for the thrust washers. That would seem to move the worm outwards by about 4mm from it's original position. I thought it would be a good idea to remove 4.00mm and to counterbore the front thrust bearing by about 3.50mm, so the worm was only out of position by 0.50mm. Apart from more work, is there likely to be any other adverse result? Thanks Pete |
