Honestly I’m not sure. I’m quite confused as to what is even going on right there. Just, how? It looks exactly like what you but that wouldn’t work. Also you might want to update your catergorys since this is V5 and not IQ
If you do it carefully, you can cut the head off of a screw and leave the threads intact, giving you a similar part.
We normally do it with hacksaw or dremel, and then screw a nut on the opposite end a few times to fix the threads.
My school has a rusty triangle file with no handle that has cut a few couplers. They take at least 10 minutes each to cut, which is very painful because we don’t have clamps or a vice unless I bring my own in. Our hacksaw doesn’t work for cutting screws because the screws are hardened steel, and the blade isn’t hard enough. Ultimately we just change our design approach to avoid requiring couplers. Buying -anything- is out of the question unless us students make it a donation.
