The Stovebolt Site Forums The Shop Area The HiPo Shop 1940 separating hubs from drums...how?

Hey guys, I'd like to remove the hubs from my drums. I don't see any rivits holding them together, and was wondering how to do it. Rather than beating on them and breaking something I thought I'd ask the experts! Thanks...Jeff

Without seeing how they are put together, I can only make a guess at what you need to do. There's a possibility that you may have to press out the wheel studs to remove the drum. Some are held on that way.

Thanks longbox, I hadn't considered that.

you can also whack them out with a hammer. put the nuts on unil they are flush with the top of the stud, remeber flush so when you whack it with the hammer you are hitting them both squarely athe same time this way you do not screw up the threads on either one as you have to take the nut off to get it apart

If you do go the hammer route, use a brass hammer. A steel hammer, even if you put the nuts on, may damage the threads.

Hold the softer hammer on the studs and hit it with a bigger hammer. Joe

Got the hubs apart today with a press. Gave that chi-com press quite a workout. Glad I didn't have to hammer them, cause they were tight! Thanks for all the tips....BTW, Joe H got any pics of that 3 carb setup? Does it perform good? I'm putting a 250 in my 40 and just picked up an Offy intake with 3 carbs, just wondering what to expect.

great tips! flush nuts, brass intermediate. i just ruined some threads on something else by non-flush, steel hammer method

you can always make a few different drivers for removing these kind of studs and for strg ends Take about a 2 or 3" section of 1" hex and drill it and tap it about 1/2" deep with corresponding thread and put it on until it bottoms and then give it a good whack with a hammer,done
there are so many cheap tools out there now albeit"china" and if they are avail locally you can buy them. lots of them don't last that long, so they are ok for home use as you may mever use them again

i follow you padre if i think 1" square or round, but, 1" hex? what's that?

All hex nuts and hex headed bolts come from hex bar stock. One of my friends has a machine shop with a number of automatic screw machines and has hex bar drop offs from 3/16 to 2.5 inches in brass, aluminum, steel, and stainless. The drop off is the last bit of bar that won't chuck up in the collet and feed so it is scrap. I get several of each size from him and use my lathe to make bolts not readily available from most fastener places; stuff like some convertible top bolts or bolts with a long shank and just a few threads on the end, or something as common as hood arm shoulder bolts.

What was available would be my guess. Anything you can drill and tap would be ok. The hex might be easier to thread on but I doubt it.

I beg to differ, coilover. While large hex nuts and special bolts certainly are made from hex stock, most standard bolts and screws are made from round stock and "cold headed"...a forging process that makes a strong, accurate, CHEAP head (hex, socket, phillips, countersunk, etc.). It's all about mass production and minimizing waste.
