I basically could do with an M5 female (internally threaded) rose joint but with a 6mm bore.

From what I've seen so far the threaded part is always the same diam as the bore.

Clearly I could adapt a fully M6 male rose joint to M5 by attaching a bit of drilled and tapped rod but that will increase the length and I could do without that (will have to remake a mount bracket and the extra length would make the whole setup weaker).

Annoying thing was I only realised this problem at the last minute when I was about to bolt everything together!

If I could stop it from spinning I could maybe drill out an M5 5mm bore rose joint to 6mm

I've emailed a couple of suppliers but if anyone knows for sure that would be cool.

Thanks.

i've got 5/8" thread with 1/2" rose joints on all my suspension, so it CAN be done, but whether you'll find those particular ones i don't know....

drilling the M5 ones out to 6mm it probably your best bet

ah, yeah, well that will be an issue where are you going to use them?

maybe light pressure on the drill, and holding the rose joint on something like a rubber sheet to make it grippy would help?

i had to slightly modify one of mine (i was going to use it for a steering rack mounting thing) and i ground it out with a dremmel if a perfect tight fit isn't entirely necessary

The insides of these are pretty hard so take a bit of drilling.

The other way around it is to put an M5 bolt through the M6 rosejoint I have (which can't have ANY play) and sleeve it up to be M6 diam.

But I don't have a lathe so I'm a bit stuck as to how I'm going to get a precision bit of tube to go over an M5 bolt to make it M6...

Could you use a 6mm rose joint with a male thread and then use a 6mm x 5mm female socket which can be made at any decent machine shop if you can't buy one.

I'm sure it's possible.

Even if they're something you've got to order from the states or something.

There's a guy on here who sells them I think.

I seem to remember Syd Bridge was pretty knowledgeable about Rose joints. Chuck a u2u his way.

You can get oversize shank rod ends for heavy duty applications, but I've never ever ever seen oversize bore rod ends. You'll just have to adapt your design to what's available.

Out of interest I asked these dudes via ebay:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=170293875818

And they sorted me out an M6 rose joint like that but internally tapped to M5. Still had to shorten it but now finally sorted. May post a video of it working later (translogic powershifter and trickshifter with autoblip combined).

And the end result (apologies for crap photo was on my back) - this is directly underneath my gearshifter lever which is being retained (in case of problems). The prop would normally obscure most of this.
