They both look usable to me. So much so that I'm tempted myself.

Whether they'll work well together is a different thing; it depends of the seal type of the vessel lid.

(I'd buy both 'cos I got a compressor too... :D)

Yes both of them will work fine, you just have to adapt the threading on the pipe work and do some mods on the pot.

Happy casting

thanks guys

now i have to talk the minister for war and finance into letting me buy them

do you think i will be able to make these more turnable, they blow apart all the time with the cracks, even more show up as you turn and bits fly everywhere

l used the same pump about 2 years ago and done not more than 15 pores which where vaccumed, mine didn't last a year and burnt the motor out:((:( l tried to get the motor repaired and was told it could not be fixed:-:((and they are a cheep import from china so if you plan to do alot of Vaccum work, buy one that can be fixed:D, not sure if lm on my own here or is there others that have had the same problems.

i got the pressure tank

i have a friend who is a fridge mechanic so i might first see if he has anything layind around that still works before i jump in and buy the vaccum pump

I think you'll need to be careful what you use to stabilize. If it contains acetone that
could affect the pump when it boils out, as it can attack rubber or plastic parts inside
the pump.

thanks for the advice, i have read that somewhere on one of the forums

what do most people use to stabilize, i know everyone has a different idea

be interesting to know what everyone thinks works best though

I've used the Minwax wood hardener and I tried the plexiglass with acetone. That didn't
help out the pump much :oo:

I just got a package in the mail yesterday with Ultraseal wood stabilizer. I'll be testing
that tomorrow. Looks promising so far. I sent them some really punky buckeye burl
(you couldn't drill it or saw it, but you could break it in half like a cracker) and they
stabilized it and sent it back. I turned it and it seems solid, looks good and it polishes
up pretty well. The bag leaked while curing so some water got in it.. not sure how much
that affected it, but I'll find out when I do my own.

thanks for the info, will have to find some wood hardner to beef up the wood

will it work under pressure only???

It will work under vacuum, but use a tall container inside the pressure pot so that
it won't all boil out..

Hold it under vacuum and then release. The vacuum doesn't pull the hardener into the wood,
it pulls the air out of it. When you remove the air, something has to replace it once the pressure
is equalized. As long as the wood is completely submerged, it will fill with hardener.

You might do that routine a few times if you can't keep the vacuum running for a long
period of time. On dense woods you might keep it under vacuum for a day or two unless
you've got some heavy duty equipment..

thanks for the info

hopefully my fridge mechanic mate can come up with an answer for me
