I need a small bushing made.

[sardine]

Just a basic part with no exact tolerances. I have a drawing of it in detail but it's basically 1.5 " diameter bar x 1.5" long , and a 20 mm bore. Mild steel.

Would have to be posted.

Anyone interested ?

I could do it for you. Does it need a reamed bore?

Got to love a good mix of units

Just showing our age i cant visualise anything over 400mm in metric

it might be imperial bar and wanting metric hole through it

Would need to know tolerance and finish required but I could do it for you?

1. Mild or any weldable carbon steel.
2. No surface finish required , part won't be visible.
3. No holes are reamed.
4. Bore is to press fit or weld in place 20 mm steel conduit ( .780" OD +/- 0.005" )

a bit more than just a steel bar with a hole in then as 1st described

Mild steel a bit hard to get a decent finish on the bore with my tooling.

A press fit bore will need a better tolerance than 5thou. A press fit would be an interference fit so it would be 0.780” +0,-(0.001” - 0.003”) or something like that.

Id say that bore wants to be reamed, easiest way to get the tolerance I’d think.

The tube end just has to get in the bore by any means, tacked on if its loose fit or reduced on a belt sander until it can be smashed on.

conduit isn't properly round anyhow its rolled and welded
