What's the strangest project you've ever seen in an old ME or MEW?

. . . . . and not one mention of an Adept lathe rebuild ?

;0)

Happy Christmas Neil

K3WL!

It has its own Wikipedia page.

"Among other activities, the kit suggested "playing hide and seek with the gamma ray source", challenging players to use the Geiger counter to locate a radioactive sample hidden in a room.^"

I have found someone's blog of making a small fusion reactor... it did generate a tiny amount of energy, much less than what was put in (not cold fusion).

ME for Jan 14th 1943 had a handy article on "Improving the Mark 2 Sten Gun"

"How to make a Desk Telephone"......

Admittedly it was April 1899 and an article within refers to Signor Marconi's successful experiments and his claim that he should be able to transmit across the Channel to France!

I passed on the majority of my old MEs a few months back but wanted to retrain the two I had from 1899 - just for this sort of topic!

Apologies for wandering off topic but I found this when moving into my current house and have always puzzled over it's origin. I'm not sure if you can read the markings on the base but it reads CART. ELEC. ENG. START. No10 Mk3 RLB. 77/7 and there is the broad arrow mark of the military. It measures 80mm dia by approx 185mm in length. Anybody here have any ideas?

It's a gas turbine engine starter cartridge. When initiated the contents burnt relatively slowly and the resulting gases were directed into a small geared turbine which engaged with the main engine, spinning it up to self sustaining speed. Certainly used on some marks of Canberra aircraft and I seem to recall also on some Hunters.

Whilst it wasn't a project, I recall a half page in an old ME devoted to methods of cleaning your pipe. Tobacco smoking pipe that is.

Included the old method of filling the bowl with salt and soaking the salt in Polish Spirit, then leaving it until the spirit had evaporated and emptying out the salt. Sort of 'de-tox your pipe bowl'.

Philip - much favoured for early gas turbine (NOT B.....Y JET!!!) powered aircraft - and viewed with keen 'interest'!! Wessex Mk1 with starter crew poised with berets 'at the ready' to damp out the residual fires. On the Belvedere, the process was considered somewhat hazardous, such that, eventually, the starter button was depressed by the pilot standing on the step and reaching inboard so that a smart retreat could be made. The 'self-igniting Belvedere' caused much merriment at Seletar when the inevitable happened on the AOC's annual inspection - the Fire crew weren't allowed to cross the runway to attend and the parading chaps were treated to a fine display of combustible Dural!! The Big Cheese was not amused

Found the item I was thinking of in my 16:36 post above. See below. But it doesn't include the salt and Polish Spirit treatment - that was obviously elsewhere.

There was a follow-up letter in "Postbag" where the writer recommended filling the bowl with Methylated spirit, drain after soaking and leave to dry for a sweet smoke.

Our Air Force used two aircraft that had Coffman cartridge starters, the borrowed DH Venoms that were used by 14 Squadron in Malaya. And in the Canberras, quite a spectacular sight with all the black smoke, specially if there is a whole squadron starting together.

I think there was something in a war time ME on lapping the crankshaft bearings for RR Merlin engines, I can't remember if it was my 3rd form metal work teacher, or someone he knew(maybe his father) did this during the war.

If there was any pipe smoking in my workshop I would think the dustbin was on fire.

This link may interest folks, its about the Packard/Rolls Royce culture clash:

Pretty sure the old Field Marshall was a 12 bore sized cartridge...Dad had one for a short time, think it went for scrap!

When I worked on Scottish Aviation Twin Pioneers, back in the 60's, they had a cartridge starter which as I recall was 12 bore size, sometimes the Alvis Leonides engines were a pig to start and consumed a number of cartridges before sluggishly coming to life.

I seem to remember in the early fifties seeing and reading an article in Model Engineer issued during the war years for the repair of leaking aluminium pans. Remember that aluminium was not available for domestic purposes, all materials were diverted for aircraft production. The article was printed to explain how to fit repair washers to the worn out part of the pan and covered repair of small holes only. Repair washers were, if my memory is correct, available from many hardware and provision stores and hung up to be torn from a cardboard sheet as required. The repair principal was for two steel washers with a small hole in the middle, each washer was dimpled, placed one inside, one outside and the steel screw provided tightened through each washer making the dimples deform the aluminium to form a seal. I assume the article was included into the ME of the time to instruct those modellers away on duty to instruct their wives, assuming that the magazine was still delivered, how to overcome a difficult domestic problem. This article has stayed with me all these years as to why ME printed the article as it seemed to me to be outside the scope of the magazine.

The Canberra aircraft was cartridge start
