    Making holes in Carpeted Bunks

    What is the best way to make a hole through carpet for a 1/4" x 20 bolt to pass to avoid a snag and wrecking it? I drilled the 3/4" PT plywood that I plan to cover with carpet already using a bit 1 size larger in diameter than the 1/4". All that I can think of is to use a pointed punch and make a starter hole in the carpet over the hole in the wood and just drive/ press the bolt through after the carpet is stapled down.

    Best to install carriage bolts before carpet. If you have to make a hole a sharp blade, punch, or something heated hot enough to burn through.

    I like the carriage bolt as its a clean installation but not sure how it would work on 3/4" PT plywood, if I would have enough material after a slight countersink of the head. I am replacing a 7.5' x 1' trailer side platform. I took a small piece of K&S tubing and heated it with a lighter and it melted a perfect hole... still on the fence as to which way to go.

    I imagine you could do a clean installation with button head or counter sunk bolts also.

    I think your on the right track- 3/4 ply - small hole poked - chalk marked - bump bolt in and snug / tighten til flush - meaning bite it a bit - not real proud but sunk . It's a carriage bolt - galvanized hardware . You hopefully didn't drill too large for the head to bite
