I need to make some motor-mount bushings, and I'm thinking poly would be the way to go. Where can I gets me some poly stock so I can chuck it on a lathe and make a mess?

McMaster-Carr.
I forgot to ask. I know next to nothing about poly bushings. Is there a particular flavor material I should be looking for?

Can't go wrong with butterscotch.

Bathroom stall walls
hockey pucks.
The garage that helped build my buddy's Jeep had several feet of body mount stock. Maybe the same durometer rating as what you need?
Ever since MrJoshua showed me the pleasure of cutting round holes out of bathroom walls, nothing else seems to fill my needs for as little initial outlay.
BTW, we checked for play and wear...
...those bathroom stall partition bushings are still good 6 years later.

Those holes, so glorious
I came for the knowledge of bushings. I stayed for the glory holes.
Are you using the solid phenolic bathroom stall material? That is an awesome idea!
For motor mounts, at least for FWD applications I would buy two-part liquid urethane and just mix and pour it into a mold. You can get various levels of hardness/stiffness. Even Energy Suspension now sells liquid urethane for those who want to make their own. I buy mine from "Eager Plastics" in Chicago since it's local. http://www.eagerplastics.com/
If for a suspension bushing that rotates, then I would buy a round bar and machine it.

Yes.
Sweet! I just got 10 coaster size color samples for a school job I'm working on. I may need to try this!
If you have a weird shaped mount buy 2 part urethane an cast them. If you have something you can make in a lathe just buy the damn bushing already made based on sizing.

I take it you've never been to the $20XX Challenge.

No, but when your piece of stock costs $10 after shipping and the bushings you need to purchase only cost $6.xx and dont require you to spend any time its a pretty easy decision.
In reply to Leafy:
Challenge math. Does not compute.

If your $10 stock piece can make 10 bushings, it's only a $1 budget hit. Way better than $6.xx.
I thought lemons math was bad.

I don't see how this is bad. You claim on budget what's on the car. You didn't use the whole $10 stick of poly, you used a portion of it. That portion goes in budget.
Pretty simple.

But you had to buy the whole stick, it still cost me $10 to make it. Do you get to claim that your turbo you added only cost $150 because you bought 10 containers full of them from china but only used one of them?

You'd count tools on the budget too, then?
