At the end of the last installment, I had the workbench top-milling task to deal with. I’ve never worked with anything this large before, so I didn’t quite know what to do. A little rough experimentation revealed that the grain reversed on the faces of the timbers about two-thirds of the way across, where the face became tangential to the growth rings (a common occurrence in this type of sawcut).
In light of this, I decided to rip the timbers at the point that the grain reversed, so that I could match the grain direction across the entire width of the top (it also didn’t hurt that there were a lot of monster knots on the “thin” side). That would give me two roughly 8″ sections that I’d be able to mill and glue up.
The first thing I needed to do was support the timbers while ripping. I had a choice between making sawbenches or just going out to get a couple of 2x4s to fill in the sawhorse brackets that I had on hand (I’d long since scavenged most of the pieces I used the last time I used the sawhorses). I opted to defer the sawbenches again and got the 2x4s.
Ripping six feet on two of these timbers was a chore, but not quite as bad as I’d expected. It helped that I sharpened my big rip saw before. In the end, I had to make four of those cuts (two at the point where the grain reversed, and two more at the ends to eliminate some excessively bashed-up wood).
So then it was on to milling. Now I really had no clue what to do. The first thing I tried to mill the edges was to fasten some handscrews in an odd arrangement to hook it to the end of my bench:

This was quite a secure arrangement, but it didn’t work for two reasons: First, there was too much junk in the shop to the right of the timber to get a jointer plane over there, and second, the timber was now far too high off the ground for me to reasonably bear down on.
After some fretting and sulking, I reminded myself that Toshio Odate wrote about how Japanese carpenters secure stuff both big and small against a wall (or something). Looking at pages 6-7 of his Japanese Woodworking Tools book, I tried to think of how I might be able to do this with with western tools. The one really important thing, it seemed to me, was to be able to keep some clearance between the end of the timber and whatever you’re securing against.
In the end, I came to this arrangement with the same sawhorses that I used to rip the timbers:

One end of the timber rests on a board with a clamped stop, and that board sits on top of the sawhorse with one end secured against a timber in the house. Here’s a look at the stop:

This is really nothing special, but it surprisingly worked quite well and I was able to mill and joint the timbers with no further ado.
Well, the “ado” would not apply to the task of lugging these timbers all over the place as I ripped, milled, and flipped them around. Ugh.
After I was finished jointing, I put the timbers side-by-side on my bench to see what I now had to deal with. Combined, they were 16 inches, and looking at this surprised me. I’d been thinking that I wanted 20″ across the top of the new bench, but now I wasn’t so sure. I believe that I’m going to trim that down to 18″, so now I need only one more 2″ wide strip to go across what will probably be the front of the bench.
The difficulty: Right now, I don’t have any pieces of douglas-fir in the appropriate size. The offcuts from the big rips are really a bit too knotty for my tastes (big knots in long-seasoned douglas-fir are essentially indestructible). I thought of getting one more timber, but then I had this other idea. I happen to have a piece of well-seasoned 8/4 beech that’s just the right length and width. Would it make sense to use that in the front? It doesn’t dent as easily as douglas-fir (even the excessively old stuff that I have).
Seems to me that it (or some other piece of hardwood) would work. Oh well, I won’t be able to work on this for two weeks now, so I’ll have that time to think about it.
