Thread: Modern boiler construction methods for the model engineer
08/04/2022 17:11:38

I love this application of modern techniques to our hobby. Brings it into the current age whilst maintaining the spirit of ME.

I think I'm a data nerd. When I was younger my cars all had as many gauges as there were things to measure...

Mild Steel?

Thread: ER16 Collets from Ebay

Trouble with ebay is it's a market-place, not a single seller..

..and I'm always astonished at how many people forget that. It's like writing off an entire town's shopping precinct because you got stiffed once at the Sunday market.

I was having a brain fart. I was thinking I'd used it incorrectly as a contraction (as in "Keith Appleton is" but obviously it had been used correctly all along. I've no idea why my scant knowledge of grammar decided to desert me completely.

For some reason I can't edit my post to remove the rogue apostrophe....

I followed Keith Appleton's advice of string initially held in place with cycanoacrylate, then painted with white (or off-white) enamel. Seems ok.

Thread: Model Turbines

I really enjoy these posts, please keep them up.



Thread: Cutting Carbon Fibre
03/04/2022 11:31:14

How on earth did he snap it!

I wonder if the cleaner solution would be to get another piece of carbon fibre and replace the shaft complete? Rods are easily found, used in everything from Model RC Aircrft and and Fishing rods as metioned before.

Thread: Myford Super 7 at SRS for only £395
03/04/2022 11:29:08

I personally think it would make for a great article.

Thread: Rumely Oil Pull engine
31/03/2022 22:25:25

I neglected to say, what a fantastic piece of engineering John.


You mentioned in an earlier post you were thinking about adding castor oil to the fuel, did you do that in the end?

Thread: "Kiv" or Kiev?

One of the ones that has annoyed me for a long time is pronouncing the children's book hero Don Quixote as Keeotay rather misses the educational connection with the word quixotic.

But wouldn't deliberately saying it wrong to fit our narrative be worse? Especially as the original is three or four hundred years old and predates any childrens variant of it by a few centuries.

Thread: Rumely Oil Pull engine

E5 petrol (the older stuff) is 5% ethanol. E10 (the new stuff) is 10% ethanol. The ethanol isn't a new addition, the quantity has just increased. As a result you may be getting it twice as bad with the new stuff, but it isn't a new problem if the ethanol genuinely is the issue.

my views/opinions don't count.

Tony, it is not that your views do not count, it is just that yours are not the *only* views that count. Moreover, taking the time to understand the world as other people see it is an enjoyable activity in its own right.

I will have to disagree with that one Callum


I'm with Callum. Your opinions do count, but yours have equal value to the other views, and some are struggling to adapt to that.

Thread: how to make it stay in ?

Unsprung weight is the enemy, so keep it lightweight!

Thread: Odd Car Boot Finds?
29/03/2022 05:08:38

Most likely a red herring but I did find this:


Visible on the small plate is PATT 5001. I wonder if it is a regulation, manufacturer or similar?

EDIT I've since read it most likely means pattern, as in the design something is made too, especially with regards to MoD equipment.

They are mentioned in passing here, specifically spark gap condensors, which could make sense..

As I understand it the frame formed storage of some of the pressurised gases.

I think Philips donated the generators to schools; I'd love to get my hands on one one day. That is obviously a visual tool to demonstrate the operation.

My grandfather made stirling engines intending to use them to power irrigation pumps in africa, but it never came to anything.

I did laugh at the Kase slice! It has a lovely finish for a workshop tool, I seldom have the patience.

Thread: Using kerosene to clean ground surfaces
24/03/2022 20:31:27

My nefarious purpose is for cleaning off Dykem Blue; after some advice on this forum I purchased Acetone via ebay recently (almost certainly over the going rate). It works very well indeed.

I suspect there will be no difference to the accuracy, but it will make your working environment smelly and is not something you want over your hands any length of time. I believe its a bit of an old school thing in the states to wipe your tools over with it, but there are far nicer, less smelly and less toxic things you could be using.

If a film of kero is affecting accuracy then you are working to a much finer tolerance than I!
