Fitting Backplate to 3"Chuck, For 4" Rotary Table
| We use the small rotary table to drill the 3 hole pattern for a 3" chuck backplate... an approach usefully suggested by "Cuppa Joe". A few extra stages were needed and, when all done and tested after, we had about 3 thou run-out in one revolution, this with the chuck and drill rod in it attached to turntable. Maybe not too awful for a real budget chuck. Wasn't best way possibly - a repeat is planned using a better method. |
