Renovating a Hardinge HLV-H

Thanks Lee :)

How soon do you hope to start turning your first part ?

Oh, I've been using it for a while now, just odds and sods (e.g. I trued up a prop-shaft bearing for my neighbour's yacht yesterday).

Now that I've sorted out the workshop, I hope to re-start the cnc conversion of the drill/mill and I've got a plan for a bed-top cnc add-on for the Hardinge similar to zepher9900's [ame="http://www.cnczone.com/forums/showthread.php?t=75106"] Feeler conversion [/ame]on cnczone; My brother wants me to make him some new wheels for his English wheel - it'll be a whole lot easier with a cnc lathe.

Bill, a fantastic job you've done! :clap: I was impressed enough at your mechanical refurbishment, but am blown away by your spindle control implementation. I'm planning on going down a different path with my Feeler, but that doesn't lessen my admiration for what you've done.

Aahh a mini Audit attachment, just needs a turret.

Kip, thanks for the kind words. If I didn't want the design copied, I would have posted photos like this. :heehee:

(now I need to shut up before Bill thumps me for hijacking his thread)

Just thought I'd post a couple of pictures of my home-brew travelling steady


(just to bump this thread above Irving's ;))

bill,it looks fantastic got a feeling this is going to prove to be your number one lathe what about the spraying would you go down that route if you found another one or resort to brush roller going to paint mine not sure what way to go your looks the bizz but is it worth the heartache

I've got the hang of spraying now (well almost :)) I sprayed my first Haighton Mill (0011) and have the second one (0020) still to do (my olympic project :))

I suppose brush and roller would be OK, but I still prefer to spray paint.

what a job never tire of going thro the pages of progress this man is an old fashion tradesman,pity he didn,t put a few more up -B

:beer:

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)
