I have lots of small salvaged electric motors laying around and I have ideas for fun shit to use them on, but how the fuck do you attach anything to the little dildo rod that comes out of it? Is there a special fitting for it that screws on tightly somehow?

>>1937251
you either cold or hot press it in ...or you get a tapered screw vice head ...or you screw it on the side ...there are tons of ways to do it

also didnt need to make a fucking thread for this oyu could have asked it n the stupid questions thread

yeah because this board moves so fast. Keep caring about inconsequential shit, faggot.

There's probably some fitting out there but most stuff that its used for (e.g. toy wheels, fans etc.) have a small enough opening to securely sit on the shaft. If I need it to attach to something I usually drill an appropriately sized hole.

I've used ink pen tubes and superglue for light duty applications like gearboxes etc. for automatons.

measure the diameter of the shaft, you can get gears that you just need to press on it

shaft coupling with a set screw, check ebay and amazon. if you're concerned with it slipping just grind a flat section into the motor shaft.

this is the correct answer op, shaft couplings are under $1 if you can wait a month for the slow boat from shenzen

>spent nearly 3 hours to remove a pulley from a motor today
the most insulting part is it wasn't even rusted on after looking at the shaft, I have no fucking clue how a pulley that was supposed to just be held by a set screw took as much punishment as it did.

sometimes tightening the screw deforms the axle
especially if there's not a groove for the screw, just like in the OPs pic
did you use oil for the job?

>> No.1940069

A bur wouldn't have survived the stuff I tried.
The shaft had a female cut for a key, but there wasn't one used. Pulley was keyless with a bolt intended to used for shafts with a flat on them instead of a normal set screw. I ended up cutting the collar off and broke it in half.
I heated the collar and put oil through the bolt hole and the end of the shaft where the pulley was but it didn't do anything.
Oil rarely works by itself if it's too stuck to do by hand from my experience,usually needs some heat. I only have a propane torch, that works for smaller stuff and when I pulled fly wheels off some small engines. Pulley was steel though so it was probably too much of a heat sync to get it up enough to make a difference since it's a 1/2 hp motor with a 6 inch sheet metal pulley.
If it wasn't known it was hammered and cut on for 3 hours you probably would think the shaft was completely fine, really odd.

On the motor shown in OP, I'd recommend putting a flat spot on the shaft so the set screw has something to hold.
