Those look pretty dang good, Tela! Looking forward to seeing how they hold up to cabbing. Thanks for showing the whole process.

Because this is my first time with CJ and with a vacuum pump, I think the next time will go a little smoother. I'm happy with the results so far, so I think it was worth the time and trouble.

I'll echo the "thank you" for documenting the process!! I'm assuming they'll cab the same as any other material you've worked which has been stabilized...but I look forward to your "review" of your own stabilization!

I see you got the oven figured out which is great. If you still have issues, I was going to suggest a small electric smoker. Of course you wouldn’t use wood in it, but they hit the 200 range and hold relatively easy. I also would use a cheap wireless temp monitor from Amazon. I got one that has a carry around monitor the size of the pager that I can clip to my belt and look at occasionally, or set alarms if the temperature goes too high or too low. I am enjoying this thread and I can’t wait to see the results!

Looks like things are working out pretty well. What kind of vacuum pump are you running? I sometimes run mine for 6 hours plus straight outdoors in hot weather. I have to pull down into a deep vacuum. I've hit as low as 35 microns which is way below. 29.9 inches of Mercury. I've not had problems with overheating. I think I have four different brands of vacuum pumps.

I got this one in a kit slickvacseal.com/products/vacuum-pumps?variant=35711674220710 The videos I have seen always mention making sure to not let it get too hot. It never got so hot that I couldn't touch it. I was playing it safe. I've never used one before, so I just didn't want to screw up and ruin my pump.

If turning it off and letting it cool is working for you it's probably best to keep doing it that way. It'll probably last a lot longer too. One of the pumps I'm using is the JB that's listed right above yours. It's a beast but it's way more pump than what you need and of course it's more than double the money. Changing oil often will help a lot with the pump life and with pulling a vacuum. In AC work and oil change is recommended every time you pump down a system. That's probably overkill for you too. Some AC people that are into lapidary save the oil and use it for slab saws.

Hey @tela have you worked any of the material you stabilized yet? I'm curious how well this works and I've been looking at a de-gassing chamber.

I've had a plate full of other stuff. My granddaughter is getting ready to graduate from William & Mary this weekend. Plus, I've been trying to by one or two used cars.

What I would like to know is if you put a cab stabilized with CJ into Acetone, what happens to the resin? My normal cabbing process is dop with CA and soak in Acetone when done usually 24 hrs to 48 hrs.

rockjunquie I have some questions for you. I know the wood is different from the rock just do't know how this may apply to rock/ I was just reading on the turntex.com site and they say, "I have been trying to do some reading about catus juice and alumilite and am confused. What is the difference and when is the appropriate useage for each? Cactus Juice is a stabilizing resin. It is used to fortify the wood itself by impregnating the cellular structure. This makes the wood harder and more resistant to moisture. It will not fill voids. Alumilite is a casting resin that is used to fill voids and cracks in the wood but does not fortify the wood. They work well together by stabilizing the wood first, then casting with Alumilite to fill in the voids and crack if needed." So are you planning to use both or just the cactus juice? Has anyone here on RTH used Cactus Juice or the Alumilite on anything vuggy? What were your results?

I planned to use CJ for some of the softer stuff and possibly Art Resin or another resin for voids. I have never heard of Alumilite.

This is what I got back: "There are no known solvents for cured Cactus Juice. Acetone will not dissolved cured Alumilite either. Curtis O. Seebeck www.TurnTex.comCactus Juice Stabilizing Solutions and Alumilite Casting Resins"
This means I could stabilize with CJ and still dop with CA and remove with acetone.
