im faz iv been doing a bit of machining for the last couple of years with my myford super 7 and my clark cl500m i have gained good experience on these little machines now i think its time to upgrade to something bigger i have found a small machine shop thats closing and is selling their edgwick series 1 lathe i know these lathes are very well built but pricing wise i cant seem to find much information on these as their are non up for sale at the moment i have been offered one for 1500 with some tooling but i am not sure if thats a good deal or not  :Doh:and would much appreciate if some of you could shine some light  if it's worth it or not as i have seen some old adds where they have sold for between 600 and 800?

My very worn Edgewick cost me 150, the seller was having trouble selling it!

 For "between 600 and 800"    I would expect to see a 3 Jaw and 4 Jaw  Chuck and a Faceplate,  start  negotiations at 400.

But if  it is near home  transport costs will obviously  be less and that needs to be taken into account too.

I paid a bit more than Matthew for my Edgwick Mk1 - about 350 IIRC. It's in reasonable nick, and whilst it does have some wear, it's good to within a thou or two if I'm really careful. Mine came with very little tooling, just a couple of chucks, and some worn out odds & sods in the swarf tray.

TBH, unless it's in fantastic order, 1500 is way too much. 500 would be nearer the mark if it's in good condition with tooling; less if there's no tooling/no faceplate/no steady/only one chuck, etc.

The Edgwick uses a unique (I think) chuck mounting system which means finding ready-to-go chucks will be a challenge. You'll almost certainly need to machine up your own backplate if you do want to put a new chuck on it. The spindle bore is a #16 Jarno (I think, somewhere around there anyway) taper, which is also unusual, and rules out buying MT spindle accessories unless you can find or make a sleeve.

The gearbox is very useful, it'll cut metric & imperial threads without needing change gears, even multi-start threads. It'll probably have an imperial leadscrew, so imperial threads can be cut using the screwcutting dial. Metric threads... you'll need to use the spindle brake & reverse without disengaging the half-nuts (although there is a bit of a workaround for that, which I think has been documented here). If you've got a metric leadscrew, then vice versa.

If you do buy it, we'll have to speak to Eric about setting up an "Edgwick Mk1 Owner's Club", I think there's a few of us now...
Cheers!

Chucks are easy to mount, a 15mm, 9/16 steel plate is all you need to make an adapter. The spindle taper an Edgwick proprietry taper, a morse taper 6 can be modified to fit.

I like the Edgewick owners section!

No way on earth would I be spending 1.5k on an old Edgwick, especially from a closing down company. It might be a minter but it's probably well down the road towards being a wreck.

I don't know where you are Faz but this 13" South Bend was on sale in Peterborough recently for half that and it's in superb condition, still has the scraping on the ways.

True enough, it'd be easy enough to make a back plate. Bear in mind, though, that unless you want to try to fit 3 bolts through the back of the spindle nose, whilst holding a chuck in the right place, then getting it to seat properly on the register.... you need to put 3 backward facing short-ish bolts through from the "wrong" side of the backplate, trapped in such a way as they can't rotate when you crank up the 3 holding nuts...

As for the spindle taper - proprietary it may be, but it's exactly 0.050" per inch, or 0.600" per foot, which is exactly the same as a Jarno taper... Trust me, I've had a bore gauge up her snout... I made (bodged, really) an ER32 collet chuck - out of aluminium, which is hardly the ideal material - and as soon as I got the taper right, it went in there snug as a bug in a rug. In fact, it took a pretty hefty thwack with the LART* to shift it...


*LART = luser ("loser") Attitude Readjustment Tool. AKA a hammer. luser is an old Unix joke.

Cheers!

I used lengths of stud, threaded int the back plate, with a tack of weld to stop them coming unscrewed! As for holding up the chuck, I use a wooden "horse" (one for each chuck) so that it is supported, no weight! It also protects the ways from chuck fall! You could use counter sunk bolts coming through from the front! Make the threaded part short enough to be able to get the nuts on when the chuck is fully home!

Hi and welcome Faz, larger machines tend to be cheaper than Myfords at the low end. i expect Edgwick/Harrisons etc now days to be around the 1k mark if they are reasonable and with some chucks/tools etc. unless they from a dealer who will probably apply VAT. Having said that there is one dealer online forget his name, who doesn't have VAT.
