Stainless split exhaust collets

[Nurse Julie]

Strange, because they don't show them fitting the 400 on their list 🤔🤔🤔. I'm sure I've got 500 ones here to get the measurements from Ted. No idea of price.

Greendhat 18233-107-000 Exhaust Collar Pipe Joint For Honda CB CL SL TL XL 100 125 200 250 400 500 550 CB100K 1970-1987 Exhaust Collars
I've measured mine and the dimensions are 40mm across the width x 26mm deep as per the listing.

I'm assuming that my 500 collars are the originals - it has a Motad exhuast system so could they be different collars on my 500?

I've tried my collars on both my 500 front pipe & against my original 400 manifold and they both fit correctly & look the same as the pipe diameters are identical?

The only way I can think of to make some Ted is to machine them out of billet stainless. They were originally made out of sheet steel which was then forced over by some sort of press, I could see how they were made by working on so many and you can see places where the metal started to split due to the stresses involved, I'd imagine they had to scrap more than a few due to excessive cracks. I did consider buying some sheet stainless at one point but the pressure needed was far beyond what an amateur could exert. Plus you'd need a mandrel etc so decided to have the OE ones ceramic coated instead. The paint I'm having applied passed a salt water test, 10,000 hours in salt water with no visible signs of rusting is the standard. Hopefully it should stop any future rusting.

Roo if you can source 2 decent collets from what you have and send them up I'll add them to my lot after doing my stuff on them, that will be 24, which is enough for 3 complete sets. Mine have a small 3mm hole in the corner so they can be hung by wire when he sprays them, I asked him and he said it would be a great help to him for getting a decent finish on them.

I can buy 8 new ones for £35 including postage to the Uk from this place  so might just replace them all.

Ted, I think the 500 collets are just longer than the 400/4 ones, the diameter is the same. I'm not going to get the chap to make the 500 ones if you don't want them. He's making a big batch for people on a 400/4 Facebook group and he lives in Boston, only 10 miles from me. I'm not ordering any for myself from him as I don't need them.

I can't commit to SS without a price Julie.

Ron says around about £40 a set.

These are ones he's made before cutting them in half.

£40 for all 8 is okay with me.

It's the postage from Japan and the chance of import duties that usually kills that idea Ted.

I've put in your order for a set Ted. I'll let you know when they are ready and you can liaise direct with Ron re payment and postage.

billet stainless ?
Sheet Steel ?

They are made from tube mild steel that is heat pressed and then cut in half.
Ron makes them from stainless that is pressed to form a collar and then cuts them in half. Same as the original process without the heat press. Very easy to do with the right tooling.
You can also do them in a lathe and spin the tube of stainless and form the lip 

[Moorey]

  They look like either Dairy or handrail tube and once the former is made which isn't difficult, pressing them with a hydraulic hand press will be easy.

I would be interested in a set for my 500 if he is willing to make more.

I'll ask him for you Mick.
