Thread: Induction heating coil offer
16/04/2016 13:59:22

I spotted this little gadget and wondered if it would be useful for hardening and tempering small items.


Some interesting items on their site.


Thread: What Did You Do Today (2016)

First record of wheel balancing.

Those early horses were fast!


Thread: How are people finding Windows 10?
30/12/2015 17:55:22

My own system in Win 7 and I found it reliably and easy to use. I couldn't be bothered with Win8.

I have heard plenty of complaints about Win 10 from friends.

It seems logical to me to wait until the last minutes of the free version before installing Win 10, if even then.

Historically, Microsoft have taken some time to iron out bugs in new operating systems, so I let them get on with it and save myself the possible hassle.


Thread: Merry Christmas to one and all!

Let me add my best wished to all those above and to all those who kindly have shared their knowledge on the Forum.

Also best wishes for a full recovery to David.


Thread: Looking for a book from the 40s/50s
20/11/2015 23:42:40


I remember a "Boys book of Make and Do" from the 50s. I wonder is that the one you are looking for?


Thread: Dehumidifiers
20/11/2015 23:16:57

I have a Dimplex model 2000 MKOC for quite a few years and it has given great service. Much more efficient than flashier looking models. Mine is dark brown, about 14" square and about 18" high. Don't know if they still produce these but they work well if you can find one.


Thread: Help to stop backlash
17/11/2015 23:54:43


Have a look at this site. It should answer some of your questions and gives the full sequence on making an acetal /delrin nut.



Thread: What did you do today (2015)

Warwick Wilton,

That unit you have sounds interesting. Any chance of a few more details on your set-up?


Thread: Motorcycle General Discussion

Maybe a little short on ground clearance?

Thread: Sharpening brazed carbide tip tools for the lathe.
12/10/2015 21:14:43

Brian, from my limited experience green wheels are slower than diamond at dressing the brazed carbide tips. Another thing I noticed was that they were inclined to slightly round the cutting edge. That might have something to do with the soft bond on the green grit wheels.

All in all, I found that the cheap diamond laps/stones from the like of Aldi/Lidl did a good quick touch-up on the tips. I'd keep an eye out for one that was box shaped with four different grit sizes along the 4 sides. At about £8 they are great value and seem to last well. Using the finest side, 200# I think is fine for final dressing the edge and the tool cuts cleanly. Personally I gave up on the green wheel for dressing tips after using the diamond stone.

Thread: How strong is wood?
21/09/2015 23:38:21


The bench you suggest would be more than adequate.

Consider Bob's suggestion above and maybe to avoid any movement due to changes in humidity why not use a bit of kitchen worktop with laminated top. I would put a coat or two of paint or varnish on the bottom surface to seal it. It comes about 2" thick and if supported by 4x2s around the edge and one across the middle it will never budge.

If you use single 4x2 for the frame and sheet it with 12mm ply screwed and glued you will eliminate any tendency to move and you have useful storage for all your bits.


Thread: ER40 collet chuck
09/09/2015 22:40:44

Dave ,

One advantage you might find with the ER40 is that you can often pick up cutters etc with thicker shafts from industry that are too big for people with smaller machinery. As a result there is less competition for them at auction.

I use one on my mill. Got my from Amadeal and have had no problems at all. I would suggest you get the ballbearing losing nut as opposed to the standard one. It is much easier to bring up the required tightness. They need more pressure than you might think.


Thread: Plastic off cuts
07/08/2015 20:53:50

I agree with Martin's point above. It seemed a generous offer of time and effort at the time and if personal problems made it not possible to fulfill the offer, well, I for one am just grateful that his problems are not my problems. I wish the man well.


Thread: What did you do today (2015)

""I then loaded the TIFFs into PIPP which automatically centres the image (among other things).

PIPP produced a new set of cropped tiffs that I put into Autostakkert! 2 which aligns them and produces a final image........."


Thanks for the detailed info. It sure is labour intensive and only for the committed and knowledgeable. In my case, it bought a line from that much loved poem of Goldsmith's to mind:

"And still they gazed, and still the wonder grew

That one small head could carry all he knew.,"


31/07/2015 22:23:09

Very fine picture Neil.

Are those circular marks with striations out from them caused by past impacts from space, or do we know?

If so they gave it quite a smack!


Thread: Signing one's work
08/07/2015 21:16:28

Clive......."A gun making friend of mine would engrave, 'Fecit' + (Name) around the muzzle of his guns"

That seems a very appropriate signiture for some of my disasters! I might leave my name off them though.



Thread: Power rating on switches. AC v. DC
20/05/2015 21:31:58

Nathan, The only ones of those I can see if for round pole and there's little room in there for adapters.

Mike, that is exactly the info I needed. Many thanks for that link.

MichaelG, I never gave micro switches a thought even though I have quite a few stashed away. I always assumed that being small they would only be for light loads. Must have another rummage.

Very grateful again to all who replied,


19/05/2015 23:27:44

Thanks to all for your input.

Neil, and Muzzer. You have given me a better idea of the "why" of it, thanks. Yes this switch will be to just cut off the current drain while the bike is stored so the contacts have just got to be robust enough to carry the load to the instrument panel and IC while the bike is starting/ running. I suppose I should check out the maximum load through it with an ammeter before I do anything.

Nathan, I have boughtt one of those switches but they are quite large and clumsy, more suitable for under the bonnet of a Land Rover!

Thank you for the link, V8Eng. I will have a look at the site. I knew though that I would learn more by throwing out the question to the Forum.

Alan, I have one, but last winter I thought that I'd top up the charge once a week or so. Well, due to senior moments in that regard I have now got a new battery fitted! You are of course right about the charging regime but I just don't like leaving electrical gadgets plugged in, but point taken.

This may come under the "silly question" category but .......

My motorcycle runs down its battery if left unused for more than a fortnight. The clock etc. never switches off, so I'm fitting a cut off switch to the lead from the battery to the computer and instrument panel. The heaviest load would be to the solenoid relay switch when the starter is activated ( not the actual load to the starter motor)

I've loads of swiches in the junk box, but none rated for 12V. Typical would be one marked 10(3)A 250AC~.

Is it safe to use AC designed switches for DC use, as in the case above?

How do you work out what DC load an AC switch can carry?

Am I right in thinking that 10(3)A means 3A continuous and 10A intermittent use. If so, how long can the intermittent periods be?

All advice will be gratefully received.


Thread: Help required with Colchester lathe
14/04/2015 22:05:02


On a Colchester Bantam the clutch engagement lever / latch assembly, has a spring and detent that holds it up in place when engaged. wormbox.bantam.jpgCould it be that you have a broken or missing spring?

If you think that a repair / disassembly writeup on doing the clutch on a Bantam would be of any help, let me know. The parts won't be the same but the same principles may apply.

On the Bantam I had to remove the leadscrew and square shaft before the apron could be removed. This is easy by removing the RH bracket holding both.
