Epoxy bubbles.

[Magellann]

Ive seen those , and heard they work quite well, but have never tried them myself.
Are the bubbles really that much of a problem for some of you fellas, because Ive never had enough to be concerned about if any.

I used to build fishing rods and once took a tour of the St Croix rod factory in Wisconsin. They told me and I have seen it elsewhere since that it is not the heat but the carbon dioxide from the flame that releases the air bubbles. At the factory, once the rod was mounted in the turning apparatus and the epoxy applied they simply passed the flame from a Bic lighter for 2 or 3 seconds under each wrap to release the bubbles and make the epoxy clear as water. It helps to not stir the mix too vigorously also.
I can do it with my propane torch or the gas stove in the kitchen and don't need to hold the epoxy close enough or long enough to warm it up.....just expose it to the Carbon Dioxide created by the combustion.

That sounds like a really good tip..thanks

Medical and dental epoxies come with dual chamber syringes and mixing nozzles like these: https://www.amazon.ca/Simpson-Strong-EMN221-RP10-Mixing-Nozzle/dp/B0055PMTP4 This allows for thorough mixing without introducing air.

that would be exactly what the pug mill does!!

I combat the bubble issue in two ways.

#1 I stir gently on a piece of paper or cardboard.
#2 I apply a thin layer of the epoxy to the stock as well as the barreled action.

Bubble free bedding EVERY time!!

Ive never had a problem with bubbles in my epoxy, I stir mine up with a small stick on a sheet of paper andit always comes out bubble free.

Same here. I use a flat sheet of paper, plastic, or even wax paper. Whatever is at hand. Then with a long toothpick or popsicle type stick I either fold it or stir it out. Then push into a lump to place as needed. Never had an issue yet, but I'm never doing more than a few inches of space at a time.
