Re: How to countersink for a carriage bolt?
Someone offered a good solution to a similar problem I had last week - and it works well: after you have your bolt hole- drill a larger hole in a piece of scrap plywood, center it over the bolt hole and temporarily fasten with short screws or clamps- use the plywood hole as a guide template. I used a hole saw but a forstner bit would give you a nice flat bottom to seat the carriage bolt head on.
