Dose anybody sell these,or are they pretty much machine em' yourself type of deal? Or McMaster Carr item and cut to size?
Goes right along with measure twice cut once. I used the pvc trick my first time around and it worked just fine without a lathe. There are tons or different sized spacers out there you just need to do some searching for the closest fit for your application.make them out of pvc pipe first, so you don't waste materials and the time making them too short.
