5mm to 2.5mm coupler

[vvviivvv]

Hello all,

in search of two x 5mm - .093 : 5mm smooth hole motor side to .093 (2.5mm) piano wire.

such as OSE has for sale which are out of stock.

Anyone have any hidden away they'd sell or know somewhere with them in stock new?

Liam, Did you try Franz Spannagel?

Hi Tyler,

I did, I need a coupler that's body is less than 18mm in diameter it's for my SAW mystic 84.

The couplers franz do are in my C5008 and 115 but they are beast's at over 22mm in dia.

im running twin 1950's one is a new motor one is a second hand job that the original owner cut the shaft down a little hence needing to be of a certain diameter

I know Jochen from MBP made the nice ones you are mentioning. However, he has closed up shop.

[vvviivvv]

Yeah, speedmaster had some too but can’t find them in stock anywhere…

Now that Tyler mentioned it, I know I had a pair of MBP wire drive couplers for a twin setup a few years back. I'll dig through the parts drawer and see if I still have them and what the dimensions were

[vvviivvv]

That would be ideal,

Still waiting for jeff wholt to get back to me with his outer dia size, but if anyone has something please let me know.

All of my wire drive collets are 5mm/2mm. I have a pair of Octura style collets that are very low profile, and I don't see why they couldn't be chucked in a lathe and bored out +0.5mm. The MBP collets I have are also 5/2, but are a little over 18mm in diameter.

Thanks for checking,
I do have access to a lathe but it’s maybe ‘beginner grade’ and this is going to be a 45k twin (loaded) setup..

Struggling to dig up anything that’s 2.5mm to be honest

[vvviivvv]

still on the hunt for a 5mm to 2.5mm piano wire coupler set

Ecomaster has them.
