How many times has this happened to you… You choose a set of plans out of your select WW-magazine and head to the shop. Sometimes you catch a glaring error in posted/printed measurement early and cross your lucky stars. On occasion, the error(s) is much better hidden and only during assembly does it jump out and bite you in your tool bag.
Well, it bit me today in the shop. I have been so careful to double, triple, quadruple measure before cutting and to leave a slight bit extra for final sizing on this project, A Shaker 7-drawer chest. I even made a couple modifications, using a long dado instead of biscuits and using floating tenons. After making 8-dust panels to fit the side panels, I notched them on the TS sled AFTER having had squared them all and sized them all. Everything looked perfect.
Then I thought I would go ahead and dry fit all 8 dust panels to the sides and rails. Everything was snug… so snug that it took several minutes to fit all 8 dust panels into 8 + 8 dados and tap them into place. Then came the BITE.
All of my dust panels came up an 1/8” short of bottoming out in the side panel dados, on BOTH sides! How could I have screwed up THIS bad? Back to the plans and drawings (A 7-DRAWER DELIGHT LINGERIE CHEST, WOOD Magazine, March 2009, pp.34-40). Where was my mistake? What did I do wrong?
Well, all I found was that I was better than within 1/64” in all measurements and angles,... in other words dead on to the claimed measurements.
SO HERE IS MY QUESTION: Why would plans ever call for having panels fit into dados without bottoming out?
The dust panels only fit 1/4”into each of the 3/8” dados (16-total). Common sense tells me they should bottom out into this 3/4” plywood panel. However, I do recognize that I have only built a hand full of furniture pieces in my WW-ing hobby and may be missing something.
SO, AM I?
All 8-dust panels have this gap, though I did make them quite snug.
It looks like I will have to deepen the notches on the dust panels another 1/8” and shorten my bottoms rails accordingly, unless there is a better way…
