Education How would one go about getting this made?

I’m trying to prototype something, however, this one piece I can’t seem to find something suitable at the dimensions needed basically one end has to connect to a RC motor while the other end has a bolt insert.

Anyone ever had anything like this made? Looking for tips on where to go and get an idea of the cost

 

Desired material? Got any drawings etc? Could easily be done by hand, perhaps not.

 

Brass, Steel, anything that isn’t flimsy basically. No drawings I’m afraid. I was thinking along the lines of attaching an actual 30mm bolt, adding some 6mm nuts but then theirs the problem of attaching it to the motor again =/

 

Mild steel should be alright? Mild Steel Billet on eBay

Then the old fashioned way of working it down by hand, does it need to be threaded? and where? What's the parts function?

I say do it by hand just assuming it isn't going to be a precision part to the extent you couldn't do it with time and care and obviously minimal costs. If I still had access to a workshop I would do one myself for postage

 

Its function would be transferring energy from the motor to a bigger gearbox so it’s just going to be rotating very fast. The only threaded part would be for the grub screw which is the threaded hole in the picture, ignore the bolt thread, and that’s a shame because I would have taken you up on it instantly lol.

Which hand tools would be required?

 

anyone with a lathe and a drill press could knock that up. I would buy a piece of metal stock, draw some plans and google a machine shop near you and pop in.

 

Maybe @Mankz can help you out with this?

 

Grab some 6mm brass bar, put it in a drill and round one end with a file, then drill out the centre hole and tap it if you want to do it yourself? Shouldn't take a machine shop more than 5mins though.

 

Umm... why me?

Stick it in a drill. and sand paper it.

 

Possibly you meant @Nexxo? He of the aluminium and brass DaVinci fabrication operation

 

Maybe. Probably. Let me get another coffee and mull that over.

 

Honestly, you could probably get close enough with a rotary tool, (or finesse with a die grinder ) and a tap & die set. Personally I love filing down metals, especially small parts by hand, makes you want to put them in a box frame when you're done too though...

 

Thanks, chaps, luckily a place up the road from me does custom parts, however, I don’t know if there's a minimum order or what not, however, it’s one of the final pieces of this puzzle before I can connect everything and hopefully not blow up. Kinda regret selling my Dremel 3000 a year back now

 

In industry they use flex couplings for this kind of application rather than a rigid connector. Rigid connectors assume everything will be aligned absolutely perfectly, which isn't in the case in the real world and so everything will sort of just wear and break without the flex coupling.

 

That's interesting to know, thank you
