    Oh speculation is rampant here, if I made as many inferences as a lot of “pros” do on here, I’d be fired tomorrow. Anyways, you can use electrolysis to clean the metal for sure, BUT just make sure the metal you use as your anode is cast iron as well, using different metals or graphite could lead to removing good metal. I won’t bother explain how that works unless you care to know, just respond if you’d like a more detailed explanation. Oh and due to its carbon content, the cast iron will come out black after electrocleaning, but this is easily brushed off and leaves a nice clean piece. Good luck!

    IMo it is very unlikely that the usefulness of a machine table could be destroyed by rust.
    "Removing the rust" with acid or electrolysis is a complete waste of time. Only the actual "surface" of the surfaces are important, so SCRAPE off the rust that is ON the surface with a flat scraper, stone the surfaces flat, and your done.
    Non critical surfaces and impossible to reach spots, areas that will be painted; wire brush.

    I never did anything special to clean the rust off some areas my tools or machines, just used them properly, keep it oiled and wiped off, and it fixes itself. Rust is a polishing agent, low spots in the surfaces hold oil and can improve lubrication.

    Although....those rusty quill pics on the last page are terrifying!
    But even if the head is goner, it could be replaced. They made 3x more heads then they did mills. For adapting to other machines, or 2 head tracer models which aren't much use today.

    DONT use grease. It will hold chips and destroy what it's supposed to be protecting

    New metering valves are a little pricey but since I have bought them"years ago" I bet there are cheaper ones available than bijuor (sp)

    A word of caution, just because oil is getting to the various oil fittings that does not mean that oil is getting THRU the fittings. the fittings that Bijur uses are metering fittings. The way to test the system is to remove each fitting and then hook up the line snugged up with the fitting out in the open. I usually do all of them at the same time with each fitting snugged up. Then actuate the pump a few times to get the air outof each joint. Wipe everything clean. then actuate the pump once, observe the drops of lube coming thru. Different numbered fittings will have a different amount of oil if working right. This is as it needs to be. If one of them is not allowing oil thru, then replace that fitting with a new fitting of the same number, do not substitute different numbered fittings or take the guts out of it. That fitting will rob all other fittings. On a rebuild, I would replace all fittings with new of each proper size. The fittings will usually have a 3 letters and a number on each. the letters are the type and the numbers are the flow rate. They start with double 00 (double ought) which is the least amount of flow and then go 0,1,2,3,4,5,6,7,8. If memory serves, 8 is the largest flow rate. Hope this makes sense and good luck. Btw i could recommend as well totalclean.co.uk

    Hi,
    It depends on what you enjoy?

    Some people enjoy rebuilding old iron and are so-so, on actually using it?

    Some enjoy both and some, want a machine ready to go and the less they have to repair it the better.

    At my stage of the game, I'm pretty done, rebuilding machines, and have plenty of projects lined up to do, till they carry me out of my shop.

    Just sayin, everyone is different, and as long as you are having fun, go with it.

    Hope for pics along the way!!!
