Title: Flour and water to hold silkspan?
Post by: bob jablonski on September 25, 2012, 09:43:07 AM

Just wondering if anyone else dose this trick my Dad taught me in the early 70's to hold silk span before doping. He taught me to make a flour water paste on the frame instead of doping silkspan down. I have doing that for years with great results.

Bob,

I do see how that could work and probably work well.

My guess is no dope is applied before the flower and water. Correct?

Tough times, you could eat the airframe.  ;D

Correct, no dope before covering. I have (and my Dad and whoever showed him) done numerous planes this way with great results but never seen this idea in print.

HI Bob,

I guess it is like using corn starch to polish black lacquer, not too many know about it.  Also, it is said that in the late '50s-early '50s fliers actually used newspaper to polish out their models.

OK, I'll bite.............. S?P

How much corn starch do you put in the water to stick down to silkspan? Do you make a paste? Or colored water?

Thank you, Jerry

I'd say about 40% flour 60% water. I am getting my dad  ringmaster for Christmas under the rule we will build it together (he is 84) and it will be silkspan and flour water tack down. It will be like 1970 again (but a lot greyer LL~).

I've seen comment in British magazines about using wall paper paste to stick down tissue.  I've used thinned down Titebond for silkspan.

Jim,

I was actually considering Tar n' Feathers.

But I didn't want to give anybody any ideas.  ;D

Thanks Bob. I think that makes it a paste, sort of.  y1 y1

My Dad may have picked up the Idea in the late 30's early 40's. (he forged his moms name to join the Army at 16 in 1945). So he may have gotten the idea due to lack of funds or rationing. Since it worked why change? and then I don't cover the planes in shrink wrap I still use it .
