Probably a horse laxative.
Seems like the pharmacy would have it too. I use Rexall, a pharmaceutical brand over here in the USA. Bare tells me it'll gook up my engines, but I run them a lot, hard and fast, and they are clean and shiny when I open them up. No varnish problems in the cylinder. However I only add enough to the fuel I buy, which comes with 17% Klotz castor, to raise it to 20%. I run 3 Tee Dees, an RR1 and a Medallion on it. The horse stuff would likely be pharmaceutical oil too.

Castor oil replacement

Hi

I ran a few tests using vegetable oil as a replacement for castor
many years ago. This was following the late Gordon Burford's experiments with them.

With only small (under 1cc) engines, i used a variety of oils from the cheap
compound ones from the supermarket to dedicated canola, safflower etc.

The motors all ran ok, despite the thinner viscosity of these oils,
HOWEVER the gumming effect on using these oils was horrendous,
if people think castor is bad, these are far worse.

These engines were not run lean as they were sport ones, and
did not want to affect the wear on them by pushing the oil levels to low
in the fuel mix.

I would use these oils as castor is almost impossible to obtain easily
here in Oz, but ether IS impossible to source.

regards

Alex

IMO there is NO substitute for Castor oil.
Let someone else/use praise the benefits of Synths.
When the engine conditions become extreme the castor provides that extra bit of protection that saves the engine..
Pharmacy /medicinal castor works 'fine', yesss it gums more, but it's a Small price to pay for a useable engine.
SIG does (did??) sell quart jugs of their finest Castor, asking a very fair price + shipping $.. very nice.
Recently dug out a few old Fast Combat motors, 2 were messed (bores and rods) from running on Klotz laced fuel instead of Castor based , not too many runs either according the the storage notes.
(IIRC..it was the popular 'new' stuff .. back then)
Everybody makes mistakes
Trick is in not repeating the more popular ones :-)

Alex I can see why ether is hard to get, same in Belgium altough I can have it without problem at my drugstore or pharmacy because they know what I use it for, it is a known fact some people sniff it. But why is castor so scarce down-under ? It is still used very frequently in hospitals over up-here.

Stumbled onto the thread… thanks all for the notes. Castor oil just isn’t common out here in Europe, but I never thought about an animal supply place. I’ve only found full synthetic buggy fuel near me, but there’s a good shop near Venice I haven’t tried…

Being in Italy, olive oil comes out of the tap and I have been told by the locals that it works … maybe I’ll sacrifice a product engine to find out.

Reginald, I could use a pharmacist like yours… The whole mess has been enough to turn me to IMAA legal gassers Although, a liter of glow does go a long way at 8cc a flight

other thought for the next supply ; what is the degumming procedure ?
or is it just that the oil that gums up less is the first pressing ?

I asked at a local horse supply place and they did not have castor oil. Such is life. I was in for something else and was just asking. I have a gallon of Baker's AAA castor oil, should I need some.

I could send you one of these 1 litre bottles but the problem nowadays is those laws about sending liquids by postal services. Any of you ever tried asking ether by your doctor's subscription ? Or know a nurse working in a hospital ? cannot be thàt difficult.

A sincere thanks for the offer Reginald. Good point though; it's tough to get the stuff shipped. And I just might bug my physician about these things, another great idea.

As for growing a batch, think anyone would take offence to a crop of ricin in my backyard? Although, I wonder if that's why castor oil is so uncommon out here... with the wars and weaponisation of things. Scary thought.

you have a point there living in italy
if you check the wikipedia page about castor oil you see that in Italy it used to be used to torture people with ; not the poison but force feed them the oil.
Regarding the poison i doubt it since it takes some chemistry skills to isolate it in strong enough concentration to be useful.

btw i can recall there was a company called aviomodelli ; try to see if they are still active and they might know where to get some locally,

Strange.. Castor oil was used for several decades in Italy as a household Purgative. Odd indeed that pharmacies at least don't currently carry it

I got mine at an Oil warehouse/chemical company. The wife just showed me a castor plant on the back deck. Looks kind of nice, different for sure. I won't be pressing the beans, likely take the whole back yard to get enough beans.
