Thread: angle plate
19/10/2019 05:33:53

Nice angle plates and thanks for sharing, I made something similar a few years ago but borrowed my friends angleplate when machining the two large sides.


Thread: low profile vise
12/10/2019 06:17:10

Nice work on the vise, must find time to make something similar for my small milling machine.


Thread: Threading on Colchester triumph 7 1/2
10/10/2019 11:09:57

Hi Sean,

There are some Colchester serial numbers available here.


Thread: Hi from Norway
05/10/2019 16:09:25

Hei Vidar,

Velkommen til forumet, godt å se andre med samme interesser fra hjemlandet.


Thread: Cutting tools - what type is most suitable?
29/09/2019 19:30:54

Hi Will,

The middle tool looks like a boring bar, you are probably right that the tool to the left is for parting (or grooving) and the two rightmost for cutting internal threads. A few tools made from HSS blanks should get you started. For advice on grinding HSS lathe tools look here or here.


Thread: ER32 collets from 20- 30mm
29/09/2019 06:16:15

Hi Jim,

A 20mm collet is normally the largest collet you get for an ER 32 chuck, I have an oversize 25mm collet for my ER 32 chuck, it is a bit shorter than the smaller capacity collets I have, but works OK. I got my 25mm collet from Gloster's Ebay shop, as mentioned by Jason.


Thread: cutter slippage using ER series collets
28/09/2019 06:05:01

Hi John,

I have never had any cutter slip in my ER chucks, I do use ball bearing closing nuts. As John R says you need a high tightening torque, 77 ft/lbs for an ER 25 size collet according to this website.


Thread: Metal stock
23/09/2019 05:35:10

I try to mark my stock much the same way as Jeff. If I don't mark it I forget what material it was.


Thread: Propane regulator with intentional restriction?
20/09/2019 07:30:50

Has anyone seen the mess it leaves when you've used a powder extinguisher in your kitchen? We were still cleaning up three hours later. I suppose, though, it wasn't as big a mess as it might have been if I'd not insisted on my parents keeping a fire extinguisher (two, in fact) in their house for just these sorts of eventualities.

Edited By Bill Phinn on 18/09/2019 23:10:57

Yes Bill,

wasn't in a kitchen though, so now I have a foam fire extinguisher, and CO2 fire extinguisher for fires in electric equipment.


Thread: Just bought an ML7, what should i do first?
15/09/2019 05:43:21
Posted by Shaun Belcher on 14/09/2019 23:44:22:

As far as i can tell with my lathe, all the nipples require H32 grade, and K68 is just applied directly to the leadscrews and gears? Is that correct?

Yes, and K68 also on the slideways, as said here.

Thread: Chester Champion 16V Milling Machine head 'dropping'
15/09/2019 05:34:56

Hi Phil,

Glad to hear that you managed to solve the problem.


Thread: Spring Tapping Guide
13/09/2019 16:19:05

Hi Vic,

Years ago I made a simple one with 10mm OD, there is a simple sketch at the end of this pdf.


Thread: Myford 254 thread dial indicator
10/09/2019 05:14:41
Posted by Philip Slater on 09/09/2019 19:09:58:

Thanks for the offer Ifoggy I'm up in North Lincolnshire so a bit far to travel. I've never machined gears but I've got a milling machine so have the tools. Thinking aloud I wonder if I could machine the gears from Tufnel. Not sure what you mean by having 2 gears, are you saying you need to change gears on the Thread dial indicator?

I used Delrin to make a 28T gear wheel for my metric lathe (3mm pitch leadscrew), it has worked well for many years so Tufnol (sheet) should work well. A 30T gear was supplied with my Thread Dial Indicator.

07/09/2019 08:27:40

Hi Shaun,

Welcome to the forum and congratulations with your "new" lathe. I don't know if you got a manual with the lathe, if not you can download one from here. And here is an article about lubricating series 7 lathes. Good luck.


Thread: Brazing torch
05/09/2019 05:45:32

Hi Stephen,

I'm using a Sievert Promatic system with a clip on 0 - 2 bar regulator on ordinary propane bottles that I can get at my local garage. It has worked very well for my brazing work.


Thread: Protecting mild steel
17/08/2019 15:07:01

Heating and dipping in oil can give a nice black finish. I usually use linseed oil on a small piece of cloth, heat the part and apply the oil until I get the finish I want. In my experience this will give some rust protection, especially if you wipe a bit of oil onto the parts occasionally.


Thread: Parting problem - Morse taper
17/08/2019 10:48:53

Steve, it depends on whether the MT1 part is through hardened or just case hardened, may it isn't very hard at all. I have cut a case-hardened shank by using a carbide tool to get through the hard skin before using a hacksaw. It was then possible to drill into the cut end (drill was a bit blunt afterwards). Good luck.


Thread: Safety Glasses
10/08/2019 11:23:44

I use my normal varifocal glasses and a face shield, as Nick says, much cheaper and it protects the hole of my face.


Thread: Is your spindle bore large enough?
09/08/2019 10:56:31

I haven't compared the internals of 38mm and 26mm spindle bore sizes, but I'm very glad I bought the 290 lathe with 38mm bore since I turn 30mm bars quite often. If there were room in my small workshop for a lathe with 50mm bore I would seriously considered such a lathe.


Thread: First Lathe

Posted by Nathan Turner 1 on 06/08/2019 18:41:49:

Thor, i think they seem to be pretty similar. I actually looked at the warco 280 as the 290 seems to be fairly pricey from them at the moment but i'd like the camlock. What kind of work have you mainly done with it ?

Edited By Nathan Turner 1 on 06/08/2019 18:55:34

I have turned small steam engines, 150mm dia. steel backplates, hard steel bars, light alloy and brass, it works well for the work I do. If you can get an Emco 11 in good condition, buy it.
