Where to buy cheap FR-4 material ?

Bean

Hi everyone, I've been playing with my LPKF mill with some FR-4 I got on e-bay.
But I need some larger pieces, anywhere from 10" to 12" wide and 10" to 18" long.
When I look on google, all I get are protoboard and place that want to sell really big sheets.
I really need unclad (no copper) at the moment, but will need single and double side too.

Anyone know of any places ?

Bean.

Besides fab houses not many people are interested in unclad FR-4, and they prefer the big sheets.

Larger size FR-4 material can be had at HAM swap meets.

Bean,

Check out McMaster-Carr.· They have single-sided and two-sided copper clad G-10/FR4 (FR4 is fire rated G-10) in 1/32" and 1/16" thicknesses.· They come in 24"x36" sheets.· I have ripped them into smaller pieces using my table saw.· If you do that, get a separate carbide-tipped blade that will be dedicated to cutting fiberglass type materials.

They also have plain G-10 sheets in a variety of sizes.

Thanks for the suggestions guys.
I found an ebay seller (that I got single and double sided FR-4 from before) that will sell be 6"x12" pieces for $0.75 each.
I'm going to get 50 of them. That should hold me for awhile.

Bean.
