    I have been kindly given an old hand operated extractor.

    It requires a good deal of restoration but is sound. I like its operation.

    I am hoping someone who has already rescued an old extractor might be able to help...

    I am thinking of getting the frames powder coated, anything to be aware of?
    The interior of the drum needs attention, can you powder coat inside the drum? Are there any alternatives?

    Thank you in advance.

    Hi There
    Just bought a similar old extractor off Trade me. I used rust remover (Phosphoric Acid), Just brush it on and wash off with water, on the whole thing including the galvanised drum. Came up realy clean. No need to powder coat just give it a good wash down and thoroughly dry before extracting.
    Janice and Chris Valentine like this.

    Only the thickness of the powder coating (1/4 - 1/3 mm). Will this affect any clearances/tolerances?

    The powder is sprayed on then baked in an oven. Any powdercoater worth their salt could do this. The restriction would be if the drum could handle the prep. They can advise on that.

    More expensive, chrome plating. Unsure of the plating over the galv, the electroplater could advise

    I also have been given one of those,needs a good do over, not too sure what i'am going to do with it, had thought of cutting it up and making into a small portable 2 frame jobby in a plastic bin when i get the time, or perhaps let it go to a good home !

    Jonathon,
    thanks for the reply and advice.
    An enquiry to a powdercoater gave an estimate (and this is ball park only because it was over the phone) of $70 for the drum plus more for the frame holder assembly, perhaps another $70. Sand blasting prep was recommended, this is done by another company at $300 per hour. Having no experience with sand blasting, I don't know whether it would take 15 mins or 2 hours. Even at one hour s/b plus powdercoating and it is getting close to the cost of a new extractor.

    A bit more research on the net suggests spray paint with food grade epoxy paint after priming. I have yet to explore availablity and cost of epoxy paint.
    I just started to sand it back by hand this morning. It is not as bad condition as I first thought.

    Hobbler, thanks for the help. I don't think clearances would be a problem. I think the cost, especially prep, is the biggest negative with powder coating.

    For those kind of prices it would be cheaper to buy a new unit.

    Heh I got one like this also..... Not rusty but pretty old, flaking red paint as well.... Gears seem to skip sometimes if Im cranking hard out.
    Any reason you want to powder coat rather than get it galvanised again?

    In Australia I'm not allowed to sell honey if it has been processed in galv equipment. Needs to be SS or food grade plastic. Not sure about powder coating being allowed??

    How about just getting a food grade drum off trademe. I bought one, size of an oil drum for about $20. I wanted it for making a smoker so had to burn the food grade lining off. Think it was used for coconut oil.
