Customer Reviews (4.6 / 5 · 5 reviews)

Michael ★★★★★

Drilled and tapped this cleanly for a jig plate and it held threads without chipping or fraying. The epoxy glass layup feels rigid as hell and barely moved when it warmed up in the shop.

Joshua ★★★★★

The thickness came out dead consistent across the whole sheet, which made cutting my spacers way less fiddly than the last batch I tried. It's stiff as hell and the edges machine clean without chipping. Drilled about 40 holes and not one blew out.

Robert ★★★★★

Machined a few brackets out of this and the edges came out clean with no chipping or fraying. It's stiffer than the plastic stock I was using before and barely moves when things heat up.
