Is there a proper name for this item or something similar?

I want to be able to fix the flange to something and have a 6mm motor spindle with a small flat on one side coming through and be locked by the little bolt in the collar.

Sometimes called a face plate?

mounting hub, face plate, backing plate, what sort of size you after, if its 40-60mm fischertechnik or meccano

it could also be a flange plate

eg. https://www.robotshop.com/uk/hubs-couplers.html

I will have a quick look on the bay.

Meccano call it a bush wheel

Thanks all, not sure of the bore on the Meccano ones, but I don't remember Meccano axles being 6mm.

It does seem to have several names, but I may have found the longest one here:- "6mm-Flange-Coupling-Optical-Axis-Support-Fixed-Seat-Steel-Rigid-Flange-Plate"

Gotta love the Chinese!

They probably translated it from German.

If my memory serves is correct Meccano bore is just under 5mm, or 3/16” in old money. I have some 3/16 BSW taps & dies which I’ve used to make threaded rods for models.

The Meccano sizes are here.

I remember the thread being a slightly odd one, because the old man got me a tap and die, and had a job to get them.
Had literally piles of Meccano when i was a kid.
All gone unfortunately.

Just checked my taps are 5/32 Whitworth, which was old 8 SWG, approx 4.1mm.

4 mm axle size if I've read that correctly, sounds about right.

(Memory is good for some stuff - I can still "see" the size of a Meccano axle after the best part of 60 years).

I can find plenty of the required item on eBay, but I've yet to find one in the UK,they're all in China. I've no problem with buying from China apart from the delivery time - I WANT IT NOW, not in a months time.

I've probably got that size. I can't ever remember using it though. I remember dad getting the tap and die and saying he'd had a job to get it.
Must say I thought I'd read or heard years ago that the Meccano threads were metric. Wrong by the look of it.
I had a load of 1/8" BSW bolts and nuts with my set, that were handy if you ran out. Bit small though really, and didn't look right.

And ayjay, I remember stuff like that. Pointless stuff really from 50 years ago, like ti was yesterday.
What day is it again today?

I finally bought a *Flanged Turntable Hub*, and I'm pleased to say that having just fitted it this morning it works a treat.

My first three Heath Robinson efforts have all failed (eventually), the last one, which I thought was the best idea failed quickest of all. The first was just a tight fit of the motors *D* spindle into the 1" ply turntable top, this eventually started to let go and so was "improved" with some PVA glue, (I could have used epoxy but I wanted to be able to get it off again if necessary) that lasted well, but didn't survive the winter.

My final effort involved screwing a piece of flat metal to the bottom of the turntable tight up to the flat on the spindle but it wore very quickly and was slipping after only one spraying session.

I took me an awful lot of searching to find one in the UK, (the name of the item being the main problem), nothing wrong with the Chinese ones proliferating on eBay (probably), except the month wait for them to arrive, I've got two large pots to get glazed by mid/late August which is before anything might have arrived from China, some were saying into September before delivery.

The robotics store has them on the shelf, tbh I haven't used them in a few years tho

They call them a *Set screw hub* and are a bit pricey at £8.80. I got mine from *Motionco* for £4.39.

Everyone seems to call them something different, which made searching for them quite laborious.
