Lionoil

[Bobdog]

Forrest brought up the use of "Lionoil" in the "Phenolic Spar Bushings" thread.
I did a little reseach that I'll pass on what I found. I quote from "A/C Maintenance" Brimm & Boggess 1940,
"Lionoil is a proprietary artical, but as it has such widespread use in the aircraft industry, it may be diccussed here. It is a clear amber colored liquid, much similar in appearance to clear varnish. It's greatest use is for protective undercoats. It may be used successfully on all kinds of metals and woods. "Lionoil" has replaced varnish as a protection for wood to a considerable extent.It is used for the interanl protection of steel tube structures and is applied by blowing the fluid through the structure with compressed air and then allowing it to drain out. Clear Lionoil may be cut or reduced with turpentine or naptha. NOTE: Never use gasoline. Two to four hours are required for it to dry dust free and from 12 to 48 hours for it to set permanently"

I also found at one site on the internet that says Lionoil was a mix of 50% varnish and 50% boiled linseed oil.

I'd really like to hear some other input on this....maybe some of you may have used it in the past...

Re: Lionoil

A long while ago, 10 years?, we had a similar problem with Luscome. The drawings for wing tank straps showed it was to have felt pads attached to the straps and they were to be soaked in lionoil.

Doug called around, and found out it was still being made at the time, the wanted to know how many 55gal barrels he wanted. Later, after a little laughter, they sent him a 5gal "sample". I recall it was a tar-looking oily stuff. Dont remember if we thinned it or not.

Re: Lionoil

The stuff I bought from AIrcraft Spruce was kind of amber coloered. I thinned it with naptha and used it to paint the bottom of the floorboards I just finished for my L2M. I was just getting ready to paint both sides O.D. when I noticed the blueprints said to coat the bottom with it, worked pretty good. It is very imortant to remember that when you use it to coat the inside of your fuselage tubes, to measure it when your draining it back out. If you get more out than you poured in, get of of avaition and get into the Linoil business

Re: Lionoil

THE PLOT THICKENS!!! I Emailed the Lion Oil Co, and they informed me that they did not make the "Lionoil" I was inquiring about. All of their products are asphalt based. Maybe someone has an old can (container) of this stuff we could get an address from............Maybe I could put and ad in Barnstormers "Lionoil Wanted". I know this is really unimportant, but I'm curious why such a widely used product dissappeared.

Re: Lionoil

If you are an EAA member, call them and ask if someone in the museum restoration shop can offer you technical assistance for an antique project. Although many folks have had good and bad experiences with EAA on various issues, their restoratino guys are probably among the best in the business. Surely they would have that kind of info in their archives.

Re: Lionoil

Nah, thats not them.

I think we found it in Mcmasters-carr ; the industrial supply references. Maybe at the library.
