Renovating a Hardinge HLV-H

[BillTodd]

I've added a few bits and pieces since finishing the renovation, so I suppose I ought to just bring this thread up to date :

I have replaced the bearings in the cross-slide, top-slide and the collet closer and repaired the closer tube (to stop the closer wobbling madly). Replaced both drive belts.

I made a Hardinge style QC tool post for it (The Hardinge ones are impossible to find in this country) , a Metric banjo & bobbins (shaped to hold the large Myford 127T translation gear) and a close up steady to enable me to cut very small threads

To allow me to cut long pitch threads <8TPI without risking damage to the gear chain, I've added extra speed controls and switches on the threading lever. This enables me to set different spindle speeds for forward stop and reverse threading easing the forces on the gears as the dog clutch engages (see:Hardinge HLV-H threading-lever speed control.mpg - YouTube)
