How tight should dowels fit?

Dowels can run a few thousandths of an inch larger or smaller than their specified diameter, leaving them tight or loose in the mating holes. Here’s an easy way to make sure that the dowels fit snug. For a 14 ” dowel, for example, drill a 14 ” hole in scrap. Test-fit the dowel in the hole.

How deep should dowels go?

The holes to accommodate the dowels should each be drilled about 1/16 of an inch deeper than 1/2 of the length of the dowel section being used. Dowels 1 1/2-inches long are commonly used, so in this case, you would drill each of your doweling holes to 13/16 of an inch in length.

The smallest dowel tested was a 1.5″ softwood dowel. Your 1″ dowel would be approximately 1/3 the strength of the 1.5″ dowels. Their weakest dowel had a safe load of 3,200# with an ultimate failure load of 5,000 – 6,000#.
