Hi George

I'm going to steer clear of the vibration stuff untill I understand it a bit better. But listen to Irving and Freddie and dont use rubber at all.

I kind of agree with you about reducing the vibration but the only way I can see to reduce spindle and motor problems is to use mechanical counter shafts and balances like in a car engine or tuned mass dampers but thats all getting very silly and complicated and I will definatlly be shot for suggestting it.....

Its sounds to me like you are at the same stage as me when I asked if it was possible to convert a pillar drill to a mill. Every one said no dont bother its too much work, but I went ahead and did it anyway ......... and yes it was a lot of work and still isnt fully sorted but I have learnt so much in the process. (and I wouldnt bother again) If its only your time then you have nothing to lose.

At least it would end the debate .......
