    New to this and need advice please

    Hi all,

    Need some help please on getting started with casting resin blanks and stabilising, I have a reasonable amount of spalted wood I got off my Grandad when we emptied his workshop, and need to get it in a form suitable for turning.

    From what I've read a vacuum chamber would be what I need, and as always, I'm on a budget. I do have a vacuum already from my vacuum chuck so that's one less thing to buy. Is the below any good for a pressure pot, it seemed the most wallet friendly option:

    Open to any hints and tips, thanks for any help and advice

    Jack

    It certainly won’t be any use as a pressure pot (not sure if that was a typo though?) but it looks like it should do pretty well for stabilising, in fact with it not having holes in the acrylic lid, it should be more suitable than a lot of others on the market.

    If you want to cast blanks do you need a pressure pot. Can you cast with out one.

    You can cast cast pen blanks without a pressure pot, but you are much more likely to get air bubbles in your blanks without using one.

    With quite a bit of trial & error you should be able to get decent bubble free blanks using Polyester resin, but there is quite a learning curve with that stuff, to get bubble free blanks that arenít brittle & chippy, itís not a resin to be used
    in the house, as it would absolutely stink the place out for days, it also needs warm dry conditions.

    Some Epoxy resins in theory, can be used for pen blanks but in practice itís very difficult to get completely bubble free casts without a pressure pot, so itís usually recommended to use a pressure pot with Epoxy.

    Polyurethane resin is just a definite no no without a pressure pot due to its quick set time.

    No No No .... do not buy this. You will not be able to stabalise a thing with it.

    It will create a vacuum probably, but once you've added the juice and turn your vacuum on, it will suck all the juice into your vacuum .... goodbye Juice and goodbye vacuum pump ...

    I wouldn't trust it even if you put the juice in a container.

    I have 2 with acrylic lids, both are cracked and crazed, but they still work. When they finally go I'll probably get one of these.

    As Paul said it isn't any good for use as a pressure pot.

    Sorry but I totally disagree with Brads comments on the vaccum chamber that you posted a link to Jack, that pot is 11Ē tall so even if you stud 6Ē blanks on end in containers there is still enough clearance above the blanks/Juice to prevent the juice being sucked up, the cracking in the lids are usually due to the holes in the acrylic lid, Iíve had the same happen myself.

    But I defiantly agree with Brad on the Turntex one he linked to, they are designed & built to the highest standards by Mr Cactus Juice himself, specifically for stabilising & if you did ever have a problem with it, I hear customer service from Curtis is second to non, not sure if you you would need the 22Ē tall one linked to though unless you was planning stabilising much longer pieces.

    Vacuum pumps will suck the juice out of any Chamber (even the Turntex ones) if not used properly.

    Metalclay also have 16” tall Turntex chamber @ £186 or 12” tall turntex chambers @ £170 which might be more suitable for small scale stabilising.

    I have my own that I made before the Turntex ones became available over here in the UK, I did sell some to a few privalaged customers, but once Metalclay started importing the Turntex ones, I knew I wouldnít be able to compete with them so discontinued making them, as there is a lot of time & money that goes into making them.

    Vacuum pumps will suck the juice out of any Chamber (even the Turntex ones) if not used properly.

    The intake is at the bottom is it not ?
    So any juice will be sucked into the pump.

    Or are we looking at a different link ?
