I have a couple of old model aircraft diesel engines, but can’t find a supplier of fuel. It seems that the only commercial fuel available is for glow plugs. Any ideas ?
I used to make my own fuel, mixing Ether, Castor oil and paraffin in equal proportions, but even ether seems hard to get today.
It is difficult to get diesel fuel these days from what was the usual sources. I’m not sure if they still do but Model Technics used to provide made up diesel fuel in three grades as well as ether and castor. If a local model shop stocks their glow fuel then they should be able to order you some.
The other more definite source is Southern Modelcraft – see the Rivers engine thread – but the problem with that is that it is only available at model shows. Give them a ring as they attend quite a few all over throughout the flying season, there may be something nearby. They have very good products and have very reasonable prices compared to most model shops.
Short of that and particularly the latter in attending specialist shows the availability of this gets ever more harder to source.
Thanks for the ideas. I live in France so postage is normally out of the question, but visit Cornwall, so hope to see a model aviation show down there one day.
When I was flying I used to correspond with someone in France- he was very keen on diesels. Can’t guarantee anything but fairly certain his address is tucked away up the loft. If I can find it tomorrow – have to go out tonight – I will let you know by PM. He may be able to help.
Model Technics still manufacure diesel fuel. 3 different mixes D1000, D2000 and D3000. Unfortunately they do not deal with the public. Most good model shops already sell their glow fuels so they should be able to get the diesel fuel. Model Technics website http://www.modeltechnics.com/diesel.htm
I have just had rather a nostalgic hour going through all the old control line correspondence but regretably to no avail. How his letters are not in the file I have no idea. However I have just emailed another control line modeller in France to see if he can help. I will keep you posted whatever the outcome.
Thanks for trying, I may have a quick shot of easystart/paraffin / castor oil. Its just for a nostalgic run up and to get my workbench all oily again. Then when in UK, get some proper stuff.
So I suppose its back to loco making – Diesel was just a little interlude.
Yesterday I tried to buy diesel fuel at my local model shop, and was told that they can no longer get it. Model Technics still supply it but couriers won't handle it. Looks like the only way to get it now is to buy from trade stands at major meetings.
I think the world might be going too paranoid for its own good. It's not as if it's difficult to make diethyl ether by dehydrating ethanol with sulphuric acid.
Or is it just that so few people actually run model aero Diesels these days?
It isn't quite as simple as you imply. You need concentrated sulphuric acid and the process is one of distillation, with due care being taken to condense the ether vapour that is released in the process.
Being heavy, excess vapour that isn't condensed to liquid tends to gather on the surface of the bench in use and naked flames will ignite it with alacrity.
