turning old fir

SWMBO and I have just finished dismantling an old house (circa 1897) salvaging whatever lumber we can. Setting aside most of the details, to get to the story, herewith. I have cut a few sections from the end of a timber, because I want to make some mementos of the house for myself and the former owners/neighbors. The grain is very tight - at least in my experience. This stuff is like trying to turn some kind of high-tech plastic. It is hard and soft at the same time. Both tough and brittle at the same time. One area has some softness which suggests dry rot, while the majority of the wood is sound. I can get a nice shaving, but only a very slim one. I have been using cutting or shearing methods, plus scraping. I have used various gouges on the outside of the project. In hollowing it out, I started with a 1 3/4" forstner bit to get the depth I want, about 4 inches. I have been using a hook with some success to expand the interior, and a home-made square-ended boring bar to flatten out the bottom of the vessel. This is some of the hardest work I have done on a lathe, because of the nature of the wood. I would rather turn ebony or hard maple or oak, than this stuff. There are some cracks of course, from the drying of the timber, and they are part of the project. I guess this will not be some delicate thin-walled object d'art, but it will be a pretty good reminder of the project which has consumed this past summer for my wife and me. I will post pics on Flickr whenever I decide the thing is done. tom koehler

Tom, there are a number of turners that prefer old-growth Doug Fir for some of the reasons you site. Check Bill Luce's work for one

For drilling you might want to consider the following. Take a spade bit, say a 1 inch, grind the top from the flat with a center point (or maybe flat with end cutters and a center point), to something more like the old time spoon bits (a gentle curve from center to edge. Put a cutting edge on the new "curved" bit. Now when you drill down, you stop at the final depth, and your bottom center is ready for sanding. The only work you have to do there, is making the transition from your turned area to the drilled area

I put a small o-ring on the drill shank to show me when to stop

This idea stolen from Dave Schweitzer

The cracks were more significant than I'd thought. Some shake in the timber provided cracks which were not apparent until the wood had been worked for awhile, and internal stresses re-adjusted. Heh. A lot of cracks or splits whoed up. I gave the partially done project a glue bath (warm water 'n glue mix) and let it dry. Some of the cracks seemed to have glued up okay - others, not so much. I continued hollowing this thing out until it just died on me. Big chunk just sorta came out at around 500 rpm or a bit less. Looking at it some more, and I just see a mass of cracks that were not apparent before, glue notwithstanding. sigh. It was taking on a kinda nice shape, too. sigh. Well, I have some more, and will try again, but different approach, somehow. tom koehler

Perhaps cutting it into planks and making a segmented bowl? Each segment would be pretty small, and since the joints overalap any give crack would be stabilized by the non-checked wood next to it or above/below it...

A good point, and something I truly did not even consider. Thanks. The house did not have a foundation, and was simply set upon wooden posts (likely cedar) set into the clay. I cut a couple of big sections from some of this wood, and will treat it just like turning wet wood (which it is) when I get to it. tom koehler
