just came here to ask this question...
bought some simple 620 baseboard in the 4.5" variety, it was $12 for 8'
can I do better? I dont see a way.
First off, 3/4" is some thick molding. Most precut molding is 1/2" and Id be hesitant to go off book. Do you buy 3/4" and plane it down? you cant plane MDF even if you wanted to. Go with some clear white pine and it comes out to be $12 for 8' at the same big box store. THen turn a third of it into saw dust on the planer, table saw to trim to height, then router.
and its the same price :(
Maybe if I used dimensional 2x6... bandsaw it in half, plane, rip, rout. doesnt seem worth it still. Tooling costs would be crazy even if the wood is cheap. assuming the wood doesnt twist itself into a spiral.
Atleast it makes you feel better about spending the money.
