Failure – A learning experience

The last couple of days haven’t been that productive.  I’m working on the legs and apron for the small table project.

The tapers on the legs aren’t as perfect as I would like.

It’s not as noticeable in the photo, but where the taper starts at the top is inconsistent.  I could probably get away with it, but because of another failure I think I will just do them over.

The next failure was with the apron glue up.

When I was working out how thick to make laminate pieces, I did a few test cuts.  I then cleaned up the cut face with a hand plane.  In the test pieces I had figured out the right thickness, including the amount of hand planning needed to clean up the cut face.  When I did the final “production” cuts, the pieces ended up a little thicker than I had planned.

I went ahead with the glue up any way.  I think the added thickness of the laminates made it difficult to press everything together.  What I didn’t notice until this morning, was that the center piece of the mold had rocked up during the clamping process.  This meant the bottom part of the lamination did get proper clamping pressure.

The first picture shows a gap in the middle of the lamination.  I might let that one pass, but the other one is on the outside lamination.  This gap will also be near the end of the apron, once I cut the excess off.  This is a total do-over.

So, off to the local hardwood supplier to pick up more lumber.

If every failure is a learning experience, I should be a genius by now!
