Sorry to revive and old topic, but I just read this discussion: http://lumberjocks.com/projects/58528
In that discussion, David suggested acrylic discs instead of MDF discs. I will probably go with MDF< but before I make that decision, I have some questions for David (or anyone else) about the acrylic alternative when using buffing compounds. (Not sandpaper) In comment #13, David suggests: “Just adhere a thin buffing pad to the disk and use whatever grit you want..”
1) I have found acrylic to be reasonably priced at McMaster-Carr. However, I am not having the same luck with “thin buffing pads”. Macmaster has these felt pads: http://www.mcmaster.com/#felt-buffing-pads/=jqvsav However, the thinnest is 1/8” thick. Is that too thick?
2) A 36” x 36” sheet is over $100. That is just cost-prohibitive. David: What alternative pad do you suggest, and where could one buy it?
3) David suggests acrylic over MDF partly because it is much flatter. Would a piece of acrylic with a buffing pad glued to it really be any more flat than MDF? I understand the acrylic alone would be.
Thanks for any info from David, or anyone else.
I don’t have enough posts on LJ to send a private message. If someone could ping David about this thread, I would appreciate it.
