Perfect perpendicular?

[hypnodave]

Trying to work out the most effective way to glue a part perfectly perpendicular to another piece; for example, a rod end glued to a disc (that would resemble an axle and wheel).

A square ?
or maybe I don't fully understand .

What size components ?

Without seeing the two pieces difficult to give an answer.

What ever you will have to make it vertical in two planes 0degrees & 180degrees.

A small engineer's square with rubber bands or magnets ought to work. Once again, showing us what you are trying to join together will help inform an answer.

I'll try to add a photo later. I'm working on 1:350 scale computer reels. I am making them both spin. Very small parts but want to make sure the rods are perfectly strraight/square to the reels.

drill a hole where the rod goes into the disk , add solvent cement to the joint , then you can move the square around the rod without worrying about pushing the rod off target .
If you don't have a small hobby square / machinist square , anything square will do , especially at that scale .
Preferably not plastic so it won't interact with any solvent cement .

These would be about 10 " reels ?
.72 mm diameter at 1/350 ?

Find a horizontal surface with a vertical end.

Lay rod on horizontal surface & offer up bottom plate on the vertical surface.
