ENOUGH!!!!

Both of you, go to your rooms!!!!
And Don, my phones off :-)

Enough already

It's like okole puka, everone has one, opinions, that is!!!

Andy is right
Don is right
I am left out

No enough

We all have our ways of doing resin

I just email the boys and tell them what I want and they send it, can't be simplier than that, right????

And it's cheaper :-)

No, go to your rooms!!!!

FWIW.

Kevin Barnes who is considered to be an expert on the subject: Barnes Molding and Casting said...

Vacuum vs. Pressure

"While both of these processes work well
separately for eliminating air bubbles in
the part, using both will often produce the
best results. Vacuum will generally
eliminate 97% of the air and low pressure
of 40-60psi can diminish the remaining
amount."

One more observation and I will go sit in the corner. I just went through this thread again to see where it went wrong. My first 2 posts were just informational. I thought I was just helping out with my thoughts, experiences and opinions. My third one was where I got a little exasperated because I felt that people were not understanding what I wrote. I realize that I may have sounded a little testy there. After that the wheels just came off. Those who actually know me know what the score is and that is good enough for me. Sorry, Gregg! B)

FWIW-
I just bought my first ModelMartin transkit. It's the '32 Ford 3-W funny car body. It comes with everything shown in the photo. There are only 2 pinholes to be found anywhere; 1 each on the tire sidewall. Casting quality is very high. I do not have a Reliable Resins casting, so I can't compare the two. I can only say that Andy knows what he's talking about.

I'm not taking sides in any argument. I paid full retail plus shipping for the kit. I am LongDistanceOperator on eBay. Here's the auction # 180181213753

I've been casting (just small stuff) successfully with molds made under pressure and no vacuum. I've also talked to a couple casters who do it part time who have both methods. Don't hold off casting looking for a vacuum pump. You at least get started playing with a pot and using pressure and pick up a pump later when you have the funds or feel the need for one.
