| John Rudd:
So the next hurdle is the fact that the leadscrew is too short by about 60-70mm..... The bevel gear is a good fit, obviously needs shimming to ensure good tooth alignment, but because the leadscrew is too short I need to do something to retain the gear on it..... Time for a beer and a think :beer: Stay tuned.... Oh by the way, here's the motor and invertor that I'm fitting next as a taster..... :coffee: |
| John Rudd:
So more shop time today.... Today's task, I decided on the key for the bevel gear....rather than broaching the keyway out to take the existing key, I decided to make a new key from brass.... |
| John Rudd:
Why? Well its softer and will shear if anything goes wrong....I also made it stepped....so it fits the original keyway in the leadscrew and fits the existing keyway in the bevel...... A perfect fit.....and some spare brass key, just in case...( so long as I dont forget where I put it....) |
| awemawson:
The base plastic cover of the Align units usually has a spare gear in it - put your spare key in there with it. |

Hi John, --- Quote ---Then there's the bush that fits in the needle brg....so plan B....make them into one..... --- End quote --- If I am reading your posts correctly you replaced the inner sleeve with a combined spacer sleeve ?? The sleeve that fits the needle bearing is a hardened and ground precision part The needle bearing will not last very long running on a turned mild steel part :( John (another one) |
