« Part 8: Waterfall Leg Cut Part 9 of Live Edge Cherry Coffee Table from the Beginning series Part 10: The hidden multiple spline miter joint! »

I will cover a few days in this entry, a little time working each day over the last few days.

I needed to mill the walnut to two glued up 3/4” thick pieces for the shelf and second leg. The boards were not completely flat nor straight, so a little jointing was necessary before putting them in the thickness planer. Who says one has to have a power jointer to get it done?

Got a nice pile of shavings out of this board:

There were 3 knots on the backsides of the board I had to fill in—there is almost no walnut available near Louisville right now—so the second board was not as clean as I’d like. The one larger not extended slightly to the good side of the board. Filled it in like I did the cherry earlier.

One thing I’ve been thinking about the last few days is, “How am I going to clamp the waterfall leg?” I hadn’t come up with a really good idea yet, so before I posted a question on LJ, I decided to google it and see if there was a good commercial clamp I should consider. In the process, I came up with the perfect answer—these shop-made clamp jigs from Wood Magazine. I had a 12×13 piece of 3/4” plywood scrap—took me all of 10 minutes to make two. These are perfect for what I need. I did notice that the notches are big enough for quick-clamps and not for parallel clamps. I wonder if I should make those notches bigger to allow for parallel clamp usage?

This project was my daughter’s idea, and she has had a say in the design. Today she came out and helped me cut the split mortises in the walnut leg. If she’s available, I’ll get her to cut the other two sets of split mortises.

I use those shop made squares with my F style clamps when I need more holding strength. I’d also use some strapping tape.

Right. I read somewhere that Irwin quick clamps actually have more clamping pressure than F clamps. And I’m assuming I’m going to need a fair amount on that joint. Maybe I’m overthinking it.

BTW, given your concerns on my multiple miter joint, I’ve decided that if the miters don’t work, I’ll just cut the splines diagonally and glue in to make the surface smooth again, then cut a long horizontal spline.

Both my smaller HF F
clamps and my big Jorgensen F clamps exert a LOT more force than my quick clamps. Those big Jorgensen F clamps are REALLY stout and I have to be careful not to crush wood with them!

I was leaning toward the long horizontal spline from the start as it seemed easier to do and more idiot proof (always a consideration in my shop). If you go with the single long spline, just remember to orient the grain across the joint (you already knew that)

I found one article, but my memory must be a bit fuzzy (unless this wasn’t the one I remember). Doesn’t meantion F claps, but does say that quick clamps clamp with more pressure than parallel clamps. Huh.

When I did my long miter glue up on my standing desk project, all I used was blue tape. I know it sounds totally wacky, but I figured clamps would just complicate things, so I just held the corners together with a lot of blue tape. Worked out great. I also just did a smooth cut, no joinery or anything. After dried, the joints are nice and strong. Obviously you are past that step, but should you ever run across it again, you could give my way a shot if you were in a bigger hurry.
