Well now it’s offically silly season.. I’m tearing down the front of my house and want to double timber frame it as I did the back of my house. (hopefully somebody can find pictures of it in the archieves and post for those interested).
Anyway I want to build Black walnut posts.. They’ll be about 10 feet tall (plus base and top) and about 24 inch in diameter.. I’d use actual logs except for two things, the likelyhood of the logs checking badly and the early wood in black walnut isn’t decay resistant. (plus it’s white and won’t go well with all the rest of the outside timbers)
Thus I’ll need to turn my own columns. I’ve figured out how to glue up 4×4’s into a circle to make the rough blank and I’ve figured out how to build a cheap lathe using mostly scrap pieces and just a little fabricating, the only problem is that I don’t know what speed to turn the column. given that I should be able to figure out the pully sizes.
I’m assuming that I’ll start out with the glued up column about 26 inch at it’s maximum but when finished it should be around 24 inches..
Oh, and if anybody has a simple method of fluting the columns I’d like to know.. I had thought of using a router and a simple guide but that would make the base flutes much wider than the flutes at the top. I believe they are also supposed to taper in width to counteract the taper that the top has..
