Coffee table progress of sorts has been made! I've been in the shop making up a jig for doing the sliding dovetails I need to continue.
These two sliding dovetails are ... more than critical ... they've got to be right and I only get one shot. It's two sliding dovetails across a veneered panel (anyone remember that panel?) that's surrounded by some nice arched aprons which are M&T into the legs.
The dovetails have to go through both aprons and the veneered panel. So there ain't no way I was gonna be able to just slice the dovetails on each part before glue up - i ain't that good, no how. Plus, these are visible dovetails ... so everything has to be perfect.
Well just before I wrecked the bike, I glued all those bits together in preparation for the big important sliding dovetail cut ... i'm just gettin' back to 'em now ...
This morning, I put together a couple guides for my router to run against. Did a couple test cuts and satisfied myself that the jig would work, and well.
Then I puttered around with moving my tool chest up off the floor and onto the counter.
Then I went about organizing my sockets into said tool chest.
Then I moved the phone to a better location.
Then the thermometer.
See a pattern, here?
Well I finally sucked it up and started measuring for where these sliding dovetails need to be. 8 or 10 measurings later to be SURE SURE, yay a distraction! It dawned on me that the frame and panels that are going into these sliding dovetails haven't been flattened yet - still some slight ridges at the joinery. Salvation!
So I pulled out the drum sander and spent a few minutes with it getting the panels a uniform, FLAT thickness. This was probably my last stall tactic and I knew it ...
So I put the jig in place. Clamped everything nice and neat.
Put "blowout" blocks on each side of the cut.
Made sure the router bit was TIGHT TIGHT in the router.
Tightened all the base plate screws, too, for good measure.
Tightened the guide collar twice.
Checked all the clamps again in case they moved on me while I wasn't lookin'.
Set the bit depth and triple checked it.
Hung the cord up so it wouldn't snag on either trip (down and back, it's a two-pass cut).
Passed the router back and forth as though making the cut a couple hundred times to be sure it wouldn't hang up on anything...
hemmed...
hawed ...
Got my dust mask on.
Got my eye goggles on.
Put my earphones on.
Knelt down and set the router in place...
Looked up at the cord to be sure it wouldn't snag.
Took a deep breath...
Turned on the router ...
Started to venture into wood - got about a quarter inch from making the cut ...
My gut ... see ... the last time I ignored my gut feeling, I laid the bike down...
So I shut the router off and shut off the lights and went into the house ... here i am, posting how big a chicken chit I am.
This is a HUGE cut. The only variable I think I have left is whether that veneer stuck down good enough and won't explode under the bit. Everything else that I can think of is checked, rechecked, rerechecked and then checked once more.
But if something goes wrong now ... i have half a coffee table that may become ruined (depending on how bad the phantom mistake is).
I do NOT want to screw this up. I also do not want to change my design to avoid this particular cut. I just ... need to dwell on it some more, that's all.
Bawk! BAWK!!
