    Default 1939 10ee Bijur pump filter housing

    Good evening all

    Iíve finally got paint on my apron, #7158 from 1939. Not going to win any awards, but thatís not the point. I will post photos once it is back together.

    But to get to that point, I need to remedy the Bijur pump situation. It is working, I tested it before disassembly, But before assembly I need to repair the filter housing. It must have had condensation water in the sump casting and the bottom of the steel housing rotted away. You can see in the attached photos.

    Does anyone have any clever ideas, how to repair the housing? I have a perfect brass scrap, and could turn something, but if thereís a better way Iím all ears!

    And another thing... does anyone know what order the filter screens should be installed?

    Thanks folks
    I greatly appreciate the dedication of the members of this site

    I’d at least call Monarch and inquire if the parts are available and get a quote. Helps keep them around to buy some parts from them. I just bought belts and a few other parts from them.

    Thanks Dinotom,
    I tried monarch, they only have the filter and screens. I will call Bijur today and see if they have any suggestions.

    Do you mind if I ask the diameter and thickness of the new filter? I just placed an order to Monarch and forgot to order the filter kit so I am considering making my own.

    Thanks and good luck.

    This is from the round dial manual. Check on Ebay for the filter replace kits. Some of the auctions in the past showed an instruction page in the kits.

    When I reassembled my pump I used 1/8 inch F26 felt from McMaster to make the filter. Worked quite well.

    You can repair that filter housing. I'd use a piece of copper pipe used for house plumbing. Cut a narrow piece like 1/4" wide, about the depth of your housing. In order to fit it to the housing, Cut the copper loop in one spot then open up the diameter until if fits over the outside of the steel housing.
    I think if you use a 3/4" or 1" diameter copper, you can have around 3/4 coverage of the patch around the outside of the housing..
    Then carefully clean and tin the housing, fit the cleaned and fluxed ring in place and sweat-solder it in place.
    Use a hammer and a dull chisel to make an ear or tab like the rest of the housing has to retain the snap-wire retainer ring.
    Aslong as the back and side of the filter is encoded, the filtering will still be good, the Vactra still has to come through the felt and screens.

    You could use steel, but it's not as easy to cut and bend as copper pipe.

    I wouldn't even bother trying to bend it, I'd just turn it. Looks like maybe a 30 minute part if you only bother to match the 2 diameters that matter and the length between them.

    Default Help on the way

    Thanks guys for the useful suggestions. I never heard back from Bijur re the replacement filter housing, but they did say it was not a retail item, so not sure if I would be able to buy one. I did buy a new old stock pump similar to the old one, and the housings look identical, so I will just turn off the donor housing and marry it to the old pump. Should have time over the weekend to get at it, will post photos when finished. I feel very lucky that so far this is the only major part that has been beyond repair (and the main spindle shifter fork, which I can harvest from a donor headstock)

    Please post some photos of the lathe. I have a 1940 sundstrand drive lathe, so they should be very similar. Does your lathe have a collet rack inside the base? 1 or 2 layers? Who was the original purchaser of your lathe?
