Thread: Pulley Sizes For An X2 Clone Conversion
23/06/2020 11:13:05

Have a look at timing belts and pulleys. The pulleys are available down to 10 tooth. I used a pair for my cnc conversion of an SX2P to enable me to move the motor closer to the spindle and give room for the z-axis drive. No problems with it.

Robbibs Timber supply marine ply to BS standards from 1.5 mm up. 5 mm up is available in five or more ply. Varnishing with epoxy resin should give good strength. They can supply full sheets or cut to size. I've had excellent service including delivery to France.

I may have missed it but I don't think anyone has mentioned yet the need to aneal the frame material before cutting. If you are using BMS it tends to distort after cutting out for the axle boxes.

I recently received an email from Dassault asking me to complete a survey about Draftight. I told them what I think of them!


Thread: Oscilloscope kits - any recommendations?
10/05/2020 10:46:24

Have a look at BitScope. It is both a dual channel analogue scope and a simple logic analyser for use with a computer via USB.



Thread: 9x19 / 9x20 lathe gearing

Don't worry if you have a gear or two missing. They are easy make if you have access to a 3D printer. See here

I've been using a gear printed in PLA for about a year now on my slightly bigger lathe with no problems. It makes a quieter machine.

Hi Robert

Perhaps you could fill in your profile then we would know which side of which pond you live.


Thread: The good bits coming out of the Covid epidemic

Greatly reduced levels of CO2 and NOx emissions.


Thread: Inconsistent access to MEW archive
21/04/2020 10:16:36

I can understand MTM's reluctance to pay for the effort of translating the archive material from Flash to HTML5 given that the income from that would be practically zero. However, I presume that they have access to the original scans in PDF format or something easily translated.

The argument against making the archive available in an easily saved format is that it would help the pirates. On the contrary, assuming pirate copies are already in the wild, it would reduce the income of the pirates as their pirate copies would become worthless. Putting PDF copies on the site would be a very simple exercise and cost very little. Agreed there will be little return except for keeping their customer base happy.


20/04/2020 16:54:16

Yes, I have recently started getting a message when I fire up Chrome telling me that Flash will no longer be supported after the end of 2020. It looks as if some work is going to be needed on the archives.

Harold Hall's book, "Lathework a Complete Course" is a good start.


Thread: Electrical help please
15/04/2020 11:36:55

Could the problem be that the impulse is being applied too frequently? Perhaps due to excessive friction somewhere. I have no experience of that clock but I see that it uses ball bearings for the balance staff. They are usually supplied in a greased condition and for clock use should be run dry to minimise friction. Did you wash them out thoroughly? Just an idea.

Any thoughts on FFP1 masks as opposed to the recommended FFP2? I have a couple of the former in the workshop for dusty jobs.


Thread: Arc Euro and Coronavirus

Best wishes to you and all the staff at ARC from France where we are further into the infection curve than you guys. Hang in there and I'm sure I'll have a shopping list for you when you can re-open.


Thread: Sanitizer

Reply from makers of Swarfega:

"Good morning

There are two ways to deal with germs (the collective name for bacteria, viruses and fungi).

We can kill them (with hand sanitisers) or we can physically wash them off (with soap and water if the hands are not too dirty, or with heavy duty hand cleaners if they are dirty).

Swarfega will do the latter. As long as the hand cleaning is thorough, any germs on the skin will be removed as part of the process – it’s the physical action that takes them away.

This is in line with WHO recommendations.

I’d recommend a second wash before eating, with just a normal soap (it can be antibac or plain, it won’t really make much difference), really just as an extra precaution.

In terms of keeping skin healthy, use the mildest cleaner possible – so if your team aren’t getting dirty at times just use a normal soap and only use the Swarfega Orange when they do get dirty (this will help look after the skin with the increased number of handwashes they’re likely to do).

I hope this helps.

Kind regards


I'll stick with the recommended soap and water.

Cooking, cleaning, shopping. We have had to stop our twice weekly cleaning lady coming and my wife's physiotherapist isn't allowed to work at present sad

Wouldn't it promote these ideas if those who are willing to communicate gave at least some minimal information about themselves in their public profiles?

Yes! Even just a rough location would help. Just county and country?

Just a thought. I use Swarfega which seems to get rid of all sorts of oil, grease etc. Just wonder if it would dissolve the virus?

Probably. Viruses are held together by a fatty layer. Remove that and the virus falls apart. So I would imagine that, like soap, Swarfega should remove that layer. Best to check with Deb though. I have just emailed them. If I get a reply I'll post it.

Posted by Neil Wyatt on 21/03/2020 17:14:17:I've just finished the second half of some carrot and coriander I made. No taste of coriander and virtually none of carrot

If it's coriander leaves, just add them right at the end of cooking, just before blitzing.
