Default Can anyone help me identify this plate?


All of the threads are SAE 3/8-16 1/4-20 and 5/16-24. The "10" stamped on the plate implies American shoe-size. I've never seen anything like these before.

OH WOW! Those look like they wouldn't be stable AT ALL....

There used to be a set really similar to these at my cousin's rink when I was a kid, but I can't think for the life of me what he said they were...

I have a pair I overhauled a while back. They sk8 quite nicely but then I like my sk8s to turn. Urethane works a treat.

Don't feel bad, I don't know either.

Are those 5 degree or zero?

The kingpins are dead vertical, 0 degrees. At first I thought it was designed to allow simple machining like on a drill press, but the toe-stop is angled so... I dunno?

The action is conventional, with a ball and socket pivot in the plate under the 3rd cushion. I'm almost certain it's an American plate as the threads are all imperial and the cushions are 'universal' sized rubber (not urethane). With their complexity and paint details of dove grey and copper in the hard-to-polish parts of the casting, they couldn't have been cheap to make.

I'll post up more pics as they come apart.

And yes, they'll get MUCH softer cushions when they go back together.

Angry So, while I am sorting this image thing out.

Here are some pix of the plates in question:






Sorry they are so big. I really don't like learning a new system.

Yup, that's the one! Do you know who made that crazy plate?

Sorry. I have no clue @ the moment.. This is not the first mystery plate I have run across, and I'm sure it will not be the last.

Looks like he cheated on his engineering classes and tests.. I see the caster angles but dang, doing it the hard way. The way the cushions are set up, makes it seem that handling would be a bit vague...

That or he was a lot more clever than you are giving him credit for.

Yeah, different for sure. Simpler to locate the moving parts, but heavy.. Adjustable ball and socket pivot keep things as tight as any other "conventional" action. It sk8s pretty nice.

Well kinda hard to tell how it works assembled. With urethane instead of rubber and having that many cushions used, your preference for hardness can be found.

Those almost have Roll-O-Way written all over them. They're like Rockets without the articulated kingpin.

I got all the way to the bottom of the thread and couldn't believe nobody else had said it.. and then here you are. I was going to say it looks like someone tried to make a Rocket with no Swingpin.

Question Could be

However, I don't think it was a Rol-O-Way. All the plates I have found from that brand had their name on them... However, absence of evidence is not evidence of absence... I have another pair of plates, very similar in design w/ no markings either, if memory serves.. I'll have to dig it out.

BTW Happy New Year.

I found this pic of a Roll-O-Way Model B from this very forum:



It's obviously (model "B") not the only plate they made, but it's different enough in principle that it may not be related. It looks like the Roll-O-Way plate has the pivot cups in the truck, inboard of the kingpins.

Not a model B, that's a Rocket. This is a model B:




The model A was an iron pivot, with a cup in the truck that rides on a prong on the plate. Model B was similar but had a hard steel pivot on the truck that rode in a cup in the hanger. Interesting that in both of these, the truck rotates perfectly on axis of the pivot, i.e. the pivot rotates in the cup, it doesn't swing back and forth.

Here's a pic of the model A that I totally horked off the internet.

Yes, it's a very odd arrangement. Turns like nothing else. Can be made to be very agile. I did a teardown post several years ago, but it's meaningless without the pictures.



You're correct, the pivots are on the plate and the cups are in the truck and they're on the wrong side of the 0 kingpin. How does it turn? amazingly well. The trick is, the kingpin is not fixed, in articulates in the plate.



BTW, if you want to sell that plate, PM me.

Default Nice pic

I see a bit more of how they work. Gotta weigh a ton though. I take it back he did know how to work it and also this skate has some caster change available.

True, but it was stamped on the jump bar in the A, B and Rocket, and this plate doesn't have one. And there's that thing hanging off the front. Maybe it's a much later effort. There are some striking similarities, hard to deny.
