Re: Rough sawn interior trim
If you have the equipment to do such a thing, yes it's possible, the question is, is it worth it. Miss one nail and you've destroyed planer and saw blades.
It is a lot of work to make your own baseboards, I know, I've done it. Buying really is much cheaper than the amount of time it will take you to do it yourself, especially if you have to invest in any tooling.
For your project I see the need for at least a planer or surface sander, electronic nail finder, and a router and table with a round over bit. That equipment will run you $500 to $1000 depending on the type and quality you choose. I can also see ripping the material down to a shorter height which means adding a table saw to the mix. You can buy new trim and install it for a fraction of the price and effort.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
