Today we had heavy winds and the power was knocked out for several hours in the afternoon, so it is a bit late in the day for the blog to post up – midnight already. Hopefully there won’t be too many typos!
Right back to it – the next step in the process was to profile the front faces of the legs. I made up a simple jig to allow me to use the router to remove most of the waste material:
Since the faces of the legs are tapering downward from a point about 10″ down from their upper ends, two diffenent set-up positions were required to do each face. It took about 30 minutes to construct the jig, another 20 to set it up and test it out, and then about an hour to process the faces.
The roughing-out on the legs all done, I could then do some planing:
It was a matter of getting the leg at the correct height, the brace locked up into place in the leg’s slot, and the dovetail on the upper end of the brace was to my relief hovering in the correct location:
For a while I thought I was missing a drawing and would need to put off further progress until I had checked some numbers on my computer at home, and then I realized it was a rather simple math problem to solve. Once that was done, I managed to lay out the intersection points of the Giant’s Arm braces and the central rail:
That’s where things more or less finished off today. Actually the camera ran out of battery juice. I have started making some test cuts in scrap as part of the calibration of the jig. Tomorrow is Sunday, so I’ll spend about half a day in the shop and expect to be able to complete the fitting of the braces. The camera battery is charging presently.
Thanks for coming by the Carpentry Way. I much appreciate all the comments received in the past week! –> on to post 39
