A Ming-Inspired Cabinet (14)

Post 14 in a continuing series....

----------------------

After completing the milling work on the pillow block pairs, the remaining cut out step was to square up the mortises and bring them to target dimension. This task I accomplished with a couple of chisels and a paring jig. The jig is a step in development from the one I made previously when tackling the same work in the 'Square Deal' tables.

First off some pieces of cedar were prepared by re-sawing, jointing and planing until to desired dimension. These were then affixed to a piece of MDF:


The cedar blocks are spaced so as to allow a pillow block pair to fit snugly in to the middle:


Then a pair of wooden blocks, leftovers from fabricating the pillow blocks that were the same width and height as the pillow blocks, were dadoed down the middle so as to accept a pair of gage blocks, like this:


The centered dadoes with gage blocks fitted served as a centerline reference, with exact 1/4" offsets both ways, against which I could place a large paring block:


The blocks could also be swapped over into a perpendicular position for the other mortise walls to be tackled:


Offsets can readily be taken using further gage blocks and another paring block, like so:


Let the chopping and paring begin!:



After the mortises were worked from the top face, the pillow block pair was removed, flipped upside-down, put back into the jig and then the paring operation performed again.

As the mortise dimensions happened to correspond to a couple of gage blocks I had on hand, once the mortises had been cleaned out and squared up I could check the fit of the gages to the mortises:


Another view:


Another pair being similarly checked:


Back to the paring:


And more checking afterwards:



After most of a day's work, one set was complete:


After another session today, both sets were through fabrication:


That completes the fabrication work on the pillow blocks. All that remains on these parts is final clean up and application of finish, which is a few months down the line. One component down, and a whole bunch to go....

Next up will be the inverted 'T' section beams. I hope you'll say tuned for further developments in that regard. Thanks for visiting the Carpentry Way.
