Scott, what size couplers?

One nifty trick is slipping a sheet of Mylar or wax paper in there, and then inflating a balloon on the inside (forcing the glass to the inside wall of the coupler). When it is all dry, you pop the balloon, and unwind the Mylar. It is a pretty cool technique...

It is a pretty cool technique...

Oh, yeah, JW, NOW you tell him... 🙄

No Ive seen it before, just forgot to raid the kiddies balloon stash before I went to the Hanger where the new "Rocket Shop" is. 😉
Too lazy to go get some.

You know
There is an un written rule.....well maybe its written now!!
In every indeavor, there there is an unpleasant task. Glassing the inside of couplers in rocket building is mine.
You know John, that balloon didnt keep the resin off my arms.
In fact, you know that resin makes your hands slippery?
Ever try to tie a balloon with slippery hands? #@&*@#! 😕
So what does one resort to when he runs out of hands?? Thats right your teeth!
Cured resin taste a lot better than uncured resin.
The nice thing about going back to it in the morning, is every thing you touch is not sticky anymore. 8)

OK, not to keep coming up with solutions after the problem is solved 😯 but here is another nifty trick -- when glassing, use really tight-fitting latex gloves. The trick is to put on 2 or 3 pairs. When one or both hands gets slopped beyond comprehension, just remove one set of gloves and WALLAH! you are good-2-go.

If you use the looser-fitting gloves (which is my typical preference) it can be hard to take off only one at a time -- the tendency is for more than one glove to come loose.

I wonder how many of these cool tricks we all take for granted? I'm sure everyone has their own bag of tricks...

GLOVES?!
I keep trying to remember those. For 43 years Ive been getting crap on my hands that stayes for 3 days. Moast mechanics today wear gloves now.(heavy canvess ones to protect from grease and knuckle busting)
My Brother does. You thing I would learn. Maybe I will remember tonight. 🙂

Scott,
You are killing me

Geese, everyone knows you just shave your arms and put that blackout wax on your teeth to solve the resin problems. Oh yeah, and lipstick to keep it off your lips. While your at it, take a picture for us as an "Example" of how to not do it. Wait, I mean how to do it....

As a matter of warning - it's not a good idea to get epoxy on your skin. EVERYONE eventually develops and allergy to it - some take longer than others. Once you are allergic, you essentially cannot work with epoxies again. One of the best known research motor makers had to completely retire from building rockets due to health problems caused by exposure to epoxy. ALWAYS wear gloves.

Oh, and with the balloon technique, you don't even need mylar. The balloon releases just fine on its own.
