--- Quote from: mat9900 on February 17, 2017, 04:40:40 AM ---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! --- End quote --- 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... |

Hi again, I have some pics of the lathe but when I try and upload I get the following message:- The madmodder.net page isn’t 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! |

Speeds when fitted with 1450rpm motor. Regards, Matthew |
| AdeV:
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. |

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. |
