What kind of Wide Five Drum is this?

[Ziggster]

Someone local is selling parts, and a chassis. This wheel/drum was on the rear axle. What is it? I’ve never seen anything like it before.

Well, it looks like a 1936-1939 Ford rim with beauty ring. Not sure about the hub it is attached to.

You could look around the inner ring and see if you can find the date stamp (ex 7 15 36). That would let you know what year it was made. There is also a Ford script stamped it.

1936 open drum

[Ziggster]

I just saw some for sale on FB but they’re now gone, but it didn’t look like the one in the pic. Were there big differences between the front and rear open drums?

[nelsb01]

Yes -- the front drum has a large opening for the front spindle where the rear drum has a small opening due to the rear axle. Note the drums should be solid, although some early production 1936 had the open drum 'spider' drums.

1936 drum would have 3 rings around the outer edge of the drum. 1937-1939 only have one ring.

1938 Ford Spider Brake Drums

Ok. Thanks! I have 37 wide five drums, and I’ve seen open drums like the one on the lower right, but never seen the one in the lower left. Cool!

Wow! That looks so cool! Thanks for sharing!

Does the drum on the lower left accommodate either a wide 5 or an earlier spoke wheel?

[Ziggster]

I found the FB ad for the open drums.

[cas3]

those are not the same, they are 3 rib 35, solid one piece. the others in my photo, and on the chassis are early 36

[cas3]

34 fordy, I do not know if it takes either wheel. I don't think so, but never measured. That drum is now in Sweden on Lars's 34 roadster

That sure looks like it could be a 5 on 5-1/2 Clayton. However the step to support the spoke wheel doesn't appear to have the little flat area at the edge. My lathe is only 10" so I couldn't get it in the chuck to take care of it anyway. Wouldn't that be great if you could go forth and back with different wheels? That would be a heck of a hunt for four hen's teeth in a bale of hay, huh? LOL

[cas3]

I think its a bolt on to make either the hub or drum replaceable if need be. Imagine there is probably some NOS drums around that nobody knows what they fit!

This one was really good on drum wear, only .15 or so, but the hub had sat outside for decades and wrecked the bearing surface. Lars had a plan to re-machine the hub to take a different bearing. He has a beautiful old school 34 highboy roadster. He's a member here...perhaps will chime in

Don and Clayton,
The first one is a two piece bolt on drum, but it's not possible to use the early 5x5-1/2 spoke wheel on it. I have no source to confirm it, but I believe this drum may have been used only as a temporary carry over design for final use of excess stock of 1932-35 rear wheel brake drum hubs with the large 1928-35 wheel bearing (B-1225-A) on the early 1936 produced cars. The second drum is a one piece cast drum with a sleeve bearing race for the smaller 1936-48 wheel bearing (68-1225-A). This drum was also only used in early 1936 production and then later superseeded by the common 1936-39 wide five rear drums we see all over. Maybe it was superseeded for cost and/or quality reasons because I believe it's easier and less expensive to cast the later rear 1936-39 drums.

Thank you Lars. That rear drum I sold you is the only one I've ever seen. Never have seen a front, like on the ute above. How did you fix the bearing issue?

Show us a pic of your roadster!

.15" is well beyond trash.
