Thats exactly it, except i dont have the luxury of moving the headstock, but the idea is the same...

I have three tailstocks, so i was thinking of removing the centres from two of them and fitting then with oilite inserts to act as bearings for the boring bar... this wil allow the bar to turn as well as be fed

I solved the problem of moving the motor by using a snake drive off my electric drill which has a low speed control

Now... how to regrind the vertical bearing face of the bed....
