Hi there!

First, a run-down for Rogers part numbers! Here's the deal:

360: A complete single Swivo tom arm (363), with one straight 310 collet plate (90 degree) and one angle 311 collet plate (75 degree). Designed for right or left side mounting.

361: A complete single Swivo tom arm (363), with one straight 310 collet plate (90 degree) and one short-angle 312 collet plate (60 degree). Designed for right or left side slightly off-center mounting.

For the collet plates themselves:

310: 90 degree straight mount

311: 75 degree angle mount (for right or left side mounting)

312: 60 degree short angle mount (for slightly off-center mounting)

Now, wasn't that fun?!! LoLoLoLo

So, it appears you're looking for the 310 90-degree straight mount. Always easy to find. The one in the picture has a cast collet nose, which break easily. You really want the machined nose, unless you need the cast to match up with collets you already have.

I believe I may have a straight collet plate, complete with an aftermarket stainless steel nose. Includes all mounting hardware, too. PM if interested!

Heres a question: Are bass drum spurs on a 22 inch bass drum supposed to have a 60 degree or a 75 degree?

Hi Adam! Yes, it gets very confusing with what collet plate to use!

You need the 75 degree plate for both the 22 and 24 inch bass drums. This was part number 311, also known as the plate "for right or left side mounting". That plate has a more acute angle than the 312 plate, which was for off-center mounting of the Swivo tom arm and also for use for bass drum legs on 18" and 20" bass drums.

I hope this info helps you and doesn't get you more confused!

Hey idrum4fun:

Thanks so much for the parts clarifiction. I was neglecting to breakdown the component parts in my question.

And thanks for your offer on the 310 (90 degree) plate. But I have a 310 plate and a 363 arm. I also have what I know understand and believe to be a 312 (60 degree) plate for mounting on the bass drum. What I believe I need is a 311 (75 degree) mounting plate. With the 312 mount, the arm is just too slanted if I try to position the plate more on the side of the bass drum which is where I'd llike to mount the plate.

Any idea where I might look for a 311 mount?

Thanks again,

Lee

Can someone tell, does this have both the 312 and 311 plates included?

Hi Lee,

Yes, both 311 and 312 plates are included! Funny that he calls the short angle one a 45 degree. To be honest, I've wondered how Rogers measured their angles for these. However, they do refer to them as 60 and 75 degree.

Just so you'll know, I won a near identical arm from this same seller about a month ago, complete with both plates (straight and 75 degree). I ended up paying a bit over $255 for it! Ouch! I expect the bidding to be about the same for this piece. It's all in really nice condition.

Vintage drum buying is making me poor!!

Cool, thanks. And yes, funny how the cash flows out . . .

As Rogers and BR show that I am! ... I wanted to mention a few things here:

I also played a Rogers-Matic Swivo pedal like ... always! There was a brief period that I went to DW, and they make a nice pedal! ... but this was not the Swivo ... then back to Swivo-Matic I went, and he has been there. Nevertheless,

A piece of the question, "weak link", like you, was in fact correct Rogers in the early '70s. This part is called "Orientation Unit", and you're right Mike, the original design was very weak and suspect copy / pulling apart. This part of the reinforced Rogers, and it never happened again! It could also be a form of retro previous models, it would be a way to go, or at least easier. All my SWIV is that I play ... (Not the NOS models for my collection, as I have 5!) ... is unity, "new" Rotary, and again, never a fault. All of my series, regardless of brand, is SWIV-Matic is the bass drum hoop installation disk ... So I can play SWIV-Matic pedal with all the different series. My main gigging SWIV-Matic is completely broken, like a pair of shoes ... And 'so smooth and beautiful! It 'a model of 1967, but updated swivel unit. Sweet! Later, "soft" and the thriller ... More ... what a hole should be!

The reason for the 60 degree plate was for the top of the drum, not bottom. The curvature is different on the bottom not the angle. If you took a 75 degree and put it on a 22 {top} the angle would not be correct. These are generally used on a 20" bass drum on top. Altho some dealers were given virgin shells to drill and would just move a 75 degree lower on the side. I do not know if this applies to 360 drums ect. I only know about Rogers. Heres a pic with the angles laid on their side and is usually the best way to tell. I have one you can have for the cost of shipping {prolly not mint}. If I can find it. lol PM me or most know my email by now. Thanks
