Hi guys. Haven't posted on this forum in many ages. I am starting a loft bed project for my granddaughter and have a question. I have purchased the typical bed frame rail attachment hardware that require you to route out the recesses in the posts to accept the mating hardware on the rail end grains. My concern is screwing the rail hardware into the end grain and will it hold competently? I am using all ash for the build and obviously ash is a heavy, dense wood, leading me to believe its dense enough to firmly hold onto a screw. I saw somewhere where it was mentioned to maybe sink dowels at the screw locations but most of them are oriented where I would still be screwing into end grain. I have plug cutters to enable me to cut plugs in the right orientation, but again, is that necessary with ash? And in either scenario....course thread or fine, but obviously with a judiciously chosen pilot hole. Thanks for all input.
