Bushings are cheap. Your labor isn't (or shouldn't be).

Die grinder in the tool post seems like a quick n dirty solution.

Demonstrating lack of judgement is probably the worst.
Not only cheap. Easier to make from scratch than they are to modify when there is no time left in the day.
They are expendable/consumable goods, not especially complicated. Needs may be covered short-term with unhardened substitutes whilst a supply of proper ones are in the mail. Or in your own muffle-furnace.

True enough. Chronic risk for the unaware.
But at least they bring their own lunch and leave the Wells Bombardier TF alone when they raid the shop fridge for ice cubes.
So who gives a toss?

When a bushing I ordered from M-C didn't show up in time, I modified what I had by drilling with a carbide bit. Still using it.

Drill bushings are not always among the thinnest of the bushing clan, but still. Hardened?
Grinding - if yah got it - you have no major issue with the workholding.
Machining might be less fun. Pigs, with great brown wings, rather than Monkeys less fun.

Buy a bushing in the size you want, for delivery tomorrow. Do something useful in the meantime, like make money...

Nah. US Treasury Po Lice take a dim view of THAT!
Use it as an excuse to BLOW money!
Carbides....Muffle furnace... Sunnen hone... CBN tooling ... VMC with 20K RPM spindle.. CMM rig to measure "stuff"... cages for monkeys, separate cages for pigs...
..meanwhile JF "go commando" and drill the damned hole to a prick-punch, then centre punch mark, don' NEED no steenkin' dreel booshing, Gringo!
But DAMN! Lookit all the new shop equipment those expert guys on PM confirmed I really needed to have!
Now . .if I can just recover that bent fender warsher that slipped under the bench.... I oughta be able to get a recommendation for a 50-ton hydraulic press to sort THAT critter's hash!
Yes. IIRC last drill fixture I designed (been a few years) you put the catalog
number on the drawing, along with the bore needed.
Jergens is the supplier I used.
