Edgwick Lathe
« on: February 16, 2017, 03:31:03 PM »
Hi all, just joined the forum here as iv bought myself a new toy in the shape of an Edgwick mk1 from Ebay:-
http://www.ebay.co.uk/itm/Edgwick-Manual-Lathe-/162373099422?hash=item25ce30df9e%3Ag%3ApJ8AAOSwjDZYiv0f&autorefresh=true&nma=true&si=5tpfgJCqG94ZA%252BygLgpEG7p3Rbc%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557

As you can see I didnt give a lot for it, have fetched it and ran it up and all seems to work ok other than the clamp on the tailstock, so so far so good!
I am intending to do a restoration on her, so will surely be on here asking for help/guidance! Matt

Matt, welcome to the forum. A few here have Edgwick lathes so you should fit in just nicely  :clap:

Why don't you pop over to the introductions sub forum and tell us a bit about yourself and why you want a lathe (Well really WHO wouldn't want a lathe  :lol: )

I'm one of the other Edgwick owners. I tried to see the advertisment on eBay for your lathe, but nothing is available as the sale is closed.So, how about some photos? I think you are the fifth Edgewick owner on here!

Looking forward to hearing more about your lathe, maybe some photos?

All the best, Matthew.

Used to have one 2 or 3 lathes ago but it was very badly worn and probably gone for scrap now. Adv had a few of the bits off it, chucks, steadies etc.

Made a couple of cross slide nuts for an Edgwick ? a while ago ?


Pressed an insert into the original nut [ too idle to make a new one ] and supplied a spare insert as well.

At this rate, we'll have to set up an Edgwick Owner's club!  :)

I bought mine a few years back (paid a bit more than you did too, but still cheap for such a large and capable lathe). I like the fact it'll do a wide range of both metric and imperial threads from the gearbox, no change gears to mess around with, and it's got a decent spindle bore. You eventually get used to the fact it'll only do 670rpm flat out...

I made a QCTP for mine fairly early into my ownership, I couldn't get on with the oem 4-way tool post.

I might be able to sort you out a replacement tailstock clamp, if yours is missing bits... I have a whole spare tailstock. Check for wear in the tailstock nut - I have about a full turn of backlash in mine, and it's only a matter of time before it tears the threads out.... they've worn very thin. Still.... it hasn't let me down yet!

Looking forward to the restoration thread :D I'd particularly like to see pictures if you have a go at the brake/clutch.... my brake doesn't work, which makes threading to shoulders an "interesting" challenge...
Cheers!

Hi AdeV, great to hear from another owner. When I get to that tailstock il give you a shout! Yes it does look a capable lathe- I have a Portass dreadnought which has taught me lots, but is too small for a lot of the work I wish to do, hence iv gone for the Edgwick.
Having threaded numerous times with the Portass changewheels I am definitely keen on the Edgwick screwcutting gearbox!
You say your top spindle speed is 670? Im pretty sure mine is 1000rpm but will have a better look when im next with it, although some of the numbers on the speed selectors are worn and hard to read. It definitely has a 5hp 1440rpm motor on it if that makes any difference.

Also thanks to John Stevenson for that info regarding cross slide nuts- again whn I get that far I will probably give you a shout- I can see joining this forum was one of my better ideas!

Your a lucky Guy! You have the 1440rpm 5 horse motor which is why you have 1000RPM, that sounds like a great lathe. I've had my Edgwick about a year now, but I haven't got much done on it! I need to get back to getting it running properly, putting a reversing switch on it and a quick change tool post that I've found for it!

All the best, Matthew

They're certainly good heavy capable lathes. Using insert tooling, I've taken 60 thou cuts (120thou off the diameter) in steel, and it's not batted an eyelid. Of course, you have to stop and let the metal cool down for a while after such abuse... I exclusively use insert tooling in mine, because I'm hopeless at grinding HSS... and Chronos do reasonably priced inserts/holders these days.

Yes, you've got the better motor there, mine's only the 3hp, not sure of it's top speed, but that does work out as 670 on the spindle in top gear. The slowest mine will go is 17rpm - great for threading, your slowest speed will be a bit faster than that. You may find the selector suggests 670 is your top speed, ignore it as you have the faster motor.

The only "gotcha" I'd say you really need to watch out for - when you go from powered drive to neutral (the big lever on the apron), watch you don't pull it past neutral as you'll end up engaging the screwcutting drive - which moves the carriage even faster! Don't ask me how I know this!! The resulting tool-crash bent a 1.5" steel bar, destroyed an insert holder, and put a decent dent in my QCTP. Fortunately, it didn't do any other damage...
Cheers!
Ade.

Hi again, I have some pics of the lathe but when I try and upload I get the following message:- The madmodder.net page isnít working.    madmodder.net is currently unable to handle this request.   HTTP ERROR 500
Any ideas what im doing wrong?
Anyway the writing on my speed selector is very worn and hard to read, but think it says 19 rpm as the slowest, 1000 as the fastest- if anyone knows better im all ears!
Also I found the serial number :- DL 2556 if that means anything to anyone?
Thanks for that "gotcha" info- now iv looked at the lever I see how easy that would be to do-i will try to be careful!

I just noticed in the eBay picture that yours came with a 3-jaw chuck held in the 4-jaw.... exactly the same as mine! I've been lucky and since managed to acquire a 3-jaw with an Edgwick fitting (I think it came from John, or it might have come with the spare parts I bought from someone who scrapped one), the chucks are a bit of a pain to change - no handy camlock fitting! Seems strange really, the tailstock has one of the  best clamping systems out there (captive lever, no spanner to mislay), one of the most versatile gearboxes of any similar-age lathe, yet the chuck is a complete batstard to change... hey ho. I ran mine as I found it for a while, but I did have a small accident one time with the double-chuck arrangement, so I've never done it since.
Cheers!

Hi again, thanks for that speed info Matthew- that makes sense, due to the wear on the numbers what I thought was 19 is 39 on the next set of 3- my mistake.
And AdeV, yes I thought the chuck mounting arrangement was strange, but thought perhaps I would make a backplate for that 3 jaw (or another 3 jaw I have in my collection if its better) at some point.

Think I still have a fixed steady for one of these lathes. I can just see the top of a steady under a bench but it's going to be a two day job with a rope round my waist and a trail of breadcrumbs before I can liberate it.

Back again!  Iv got around to looking at the non-working tailstock clamp- but being thick I cant see how it is supposed to work! Iv uploaded a pic of the underside of it- do any of the other Edgwick owners on here know whats missing/wrong that makes it "pull up" when rotated?

Is that an eccentric cam on the end of the locking shaft? If so presumably it forces the 'shoe' in which it rides against whatever is next to it  :thumbup:

Thanks Ade. I don't think its a cam on the end- the unit need to pull vertically upwards to clamp against the underside of the bed- not sideways.  So being as thick as I am I can't see how it is supposed to do that. Hopefully Ade can shed some light on the matter..............

Matt,

This is a typical tailstock clamp. As you can see the clamp plate is pulled up by an eccentric when the locking handle is turned.



I guess your Edgwick will use a similar system. Often there's a nylock nut under the plate to adjust the clamping point.

[Edit: I see from Ade's photos it's nothing like the one above.

A bit of a mystery as to why the screw doesn't turn when you operate the handle.

Or perhaps it does and that may be the problem.]

Phil.

Turns out it's a pretty simple mechanism actually... there's a base plate (the "shoe"), and a clamping "thing". The bar that goes up from the "shoe" to the lever is threaded, as you turn the lever it tightens, raising the base plate which squishes the clamping "thing" against the underside of the ways.

See photos (click to embiggen as usual):



Lever in unlocked position:


Lever in locked position (note: more thread sticking out of the top):



Looking at your photo Matt, I think all you need to do is to tighten that threaded bar up so it's just touching the bottom of the shoe when the lever is at the back of the tailstock. I'm going to take a wild guess that it'll be quite stiff, I'm assuming the lump on the bottom is designed to bind slightly in the "shoe" so the lever tends to tighten on the thread, rather than just rotating the whole piece. If not, then I'd tighten it anyway, then wedge a shim in there so that it binds up.
Cheers!
Ade.

To adjust the tail-stock lever, remove tail-stock, rotate the  clamping bolt to screw into the handle. it is probable that the clamping mechanism has turned a full turn when it was removed at some stage. I would start by removing the tail-stock and turning the whole locking shoe a full turn so that the that the acme screw screws into the handle, thus shortening it. I don't understand why the image won't open on it's own, it's a .pdf!

Thanks very much guys- I was missing the fact that the handle is threaded onto the vertical bolt- I thought perhaps there was something missing off the bottom that raised the shoe.  The round piece turns inside the show so will need shimming out somehow as Ade suggested- anyway now i know what the issue is I will see what I can sort.  Thanks again, Matt

You  shouldn't need shims, take of the head stock, rotate the locking shoe so that the locking bolt screws into the handle a turn and try it again. As I said before, it is probable tha the locking mechanism was turned a full turn when somebody removed it. It won't have worn enough to no longer lock in it's life time!

If the bolt rotates, then there is a problem with the shoe. The slot should be straight cut and a close fit to the head. The design is not unlike the Boxford, and I dare say, a lot of other lathes, in that you can adjust the length of the screw by 1/6th of a turn by pushing the shoe up so that the head of the bolt disengages with the slot, then rotating it.

From the picture in post #20 it does rather look as though someone in the past has replaced the hex headed bolt with one that had a larger head that has been turned down to fit the slot, but doesn't grip - unless as I said in an earlier reply the circular head is actually eccentric and locks against the shoe.  :scratch:

I just went back to the original pick, I had missed that it had been turned round. Andrew's solution is probably the easiest if you haven't got a welder to put a ridge on the head of the bolt. Normally the hex head is held in place in the groove.
Although Andrew's solution is viable, it will leave slack in the movement. Four welds to transform the head into a squar would eliminat play!

How about making a simple clamp to stop the head turning:



A grub screw (or 2) from the side could lock the round head. The width of the block could be a snug fit in the slot in the shoe.

I realised I hadn't looked under the shoe to see what was there... and sure enough, it's a ruddy great bolt head:



So I'd be tempted to go with Matt's solution: Adjust so it works, then weld to the bolt head so it jams in the shoe.
Cheers!

I have found a nut the correct size- so I am going to turn the "lump" on the end of the bolt down to the size of the hole in the nut, then weld it on. Then it will be as it was originally. I will post some pics when i've done it, but thanks for all the info guys.
