Thread: Childhood diseases
23/05/2019 12:50:22

Hi Danny,

You can get measles outbreaks in areas with low vaccination coverage, for instance from non-vaccinated visitors, and vaccination causes less trouble than getting measles. If you are vaccinated or had measles as a child you should be well protected. A high vaccination coverage against childhood diseases is an effective way of preventing outbreaks.

Thread: Mini-Lathe setup for an absolute beginner?
21/05/2019 13:45:44

Hi James,

Welcome to the forum.

1. Many model engineers use a Mini-Lathe for their work, so I guess it might be sensible for you to buy one.

2. I have bought several items from ArcEuroTrade and have always received excellent service, I don't think
you need to worry.

3.Brushless motors should be Ok.

4. The older Mini-Lathes with a brushed motor sometimes had controller problems. I have an old Mini-Mill
(same brushed motor and controller as older Mini-Lathes as far as I know) that is over a decade old and
have had no problems.

4. I live in a country that adopted the metre convention in 1875 so I would say a metric lathe, others may
have a different opinion.

5. For cutting aluminium and plastic HSS tools should do Ok, I myself use both Carbide and HSS tools
depending on the job at hand.

I am old and have back troubles so I wouldn't carry it up a flight of stairs alone, I would ask a friend to assist me. Good luck.


Thread: Potty Mill engine materials list wanted
21/05/2019 06:16:38

Hi John,

I can't remember having seen a materials list (someone else will probably point you in the right direction), but there is a Parts List on this drawing set.


Thread: HSS or CS taps and dies
20/05/2019 13:29:01

Hi Adrian,

I have bought several CS taps from Tracy Tools and they have worked well for many years. They have mainly been used for tapping in gunmetal and brass as I have a set of serial taps I use for steel.


Thread: oil for lubricating lathe
19/05/2019 11:32:27

The Boxford Know Your Lathe book recommends these oils:

Esso Esstic 55
Mobil Vactra Heavy
Shell Carnea 41

or any light machine oil SAE 20 (around ISO 46)

Thread: EMCO Compact 5
11/05/2019 07:55:17

Hi William,

Congratulations with your "new" lathe. I have got an old Emco Compact 8 lathe (a bit bigger than the Compact 5) and it has served me well for decades, if the Compact 5 is not worn/damaged you should be able to achieve good results. I don't know if you have the manual, if not it seems it can be downloaded here.


Thread: Downloadable issues
11/05/2019 06:29:37

Hi Neil,

This was discussed here recently and it seems your best bet is to print to PDF and save the PDF version, read Paul Lousick's post in the link, he seems to have found a solution.

Thread: Turning Cast Iron question - Health & Cleaning Up
06/05/2019 10:05:06
Posted by Paul Lousick on 06/05/2019 07:25:30:

I have a machinist friend who hates turning cast iron as he is alergic to the dust. Care must also be taken if using a vacuum clenber (AKA Hoover) as the dust is electrically conductive and can short out the motor.


Forgot to mention that the dust end up in the water at the bottom of my old vacuum cleaner, so I have never had any short-circuit problems.


06/05/2019 04:41:13

Hi Jim,

I have turned (and milled) a few cast iron items and I try to cover the slideways of the lathe and I wear a dust mask. After I have finished turning I use the old Hoover.


Thread: Which milling cutter shank for ER collets
03/05/2019 19:19:38

I often use threaded shank end mills or slot drills in my ER chucks without any problems, just remember that the nuts on ER chucks need to be tightened with a fairly high torque.


Thread: Tracy Tools
03/05/2019 13:01:37

I have ordered taps and dies from Tracy Tools several times and I am very satisfied with the items I received.


Thread: Removing Flux
02/05/2019 10:43:12

Hi Paul,

Diluted sulphuric acid is often used for pickling, but must be handled carefully. I now use citric acid in warm water.


Thread: 2mt Myford Collet
01/05/2019 05:49:22
I am looking for a 3/64" Myford collet if anyone has a spare, once I obtain that elusive one I have a full set.

I will probably never use it, but it annoys the hell out of me that I dont have one !!


If you can't find one you could try and make one?

Very nice work Gerald, thanks for sharing.


Thread: Brazing steel
28/04/2019 05:51:03

Hi David,

I have silver soldered (brazed) mild steel to leaded free-cutting steel without any problems when fabricating a small cylinder for a steam/compressed air engine.


Thread: What a brilliant young man
19/04/2019 12:47:44

 Yes, very impressive. Same guy as in this post?

Thread: No 20 machine oil
13/04/2019 08:55:00
Posted by AdrianR on 13/04/2019 08:38:33:

I have been reading about the effects of sulphur used in the EP additives on yellow metal bearings. Are hydraulic oils free from sulphur and compatible with yellow metal bearings?


Hydraulic oils have many additives, usually also anti-wear additives (like zinc dialkyldithiophosphate), see here, or here. Sulphur based EP additives may attack yellow metal bearings. But I have never experienced any problem with hydraulic oil and yellow metal bearings.


Thread: Black Holes
12/04/2019 17:38:07

Danny, you are not the only one with a workshop floor that acts like a black holewink


Thread: Lathe idenification
11/04/2019 10:15:08

Hi Gerard,

You may be right about it being a Honden, don't know much of the Honden but I think I have the manual and I have made a few tools for the lathe, also sendt you a PM.
