the Carpentry Way: Trellis - all about it(?) Part Two
Today's boo-boo - I'm on some sort of hot streak here - involved my finger meeting the hollow chisel mortiser in an untoward manner:
I'll spare you the graphic photos. It's really not too bad. In fact, I understand that black electrical tape bandages are all the rage among the fashion-conscious set.
Moving along with trellis 2. Time for the rod mortises to receive their trenched abutments for the two shachi pins that will be employed:
Some chisel work ensues:
This one is done, and seven more to go:
Here's the next one:
The rest, well, much the same.
A tusk tenon mortising session was next on the list:
Squinted abutments done, save for final trimming if required during fitment:
I guess a few 'peaces' can now go together with their crosswise mates:
The mitered abutments have only been rough-trimmed at this point. I prefer to leave final fitting and fettling of the joinery for the morning when I am fresh.
Another piece can be added to the puzzle - you can see where I made the shachi sen abutments earlier, with the remaining half of the abutment yet to be cut on the 'peaces':
With the upper frame ring loosely slung together, I parked it on the post assembly for the moment:
In case you're wondering what hell I'm up to, here's the basic arrangement of this two-tier trellis:
The 'peaces' are about 2" too long at this point and will be trimmed back so there is the same projection on both halves of the joint.
At this point I need to trim the mitered abutments to close about a 1/32" (0.5mm) gap on each side:
A look at a couple of other preliminary corner assemblies - you can see in this photo how there is a corresponding 1/32" gap on the end of the rod tenon:
Ultimately, you want a clearance gap on the end of the rod tenon when all is snugged up for final fit, and not have it bottom out, which is a common error in cutting this joint.
Another corner, this time from the interior view:
All for now, hope you enjoyed the tour of today's wood butchery. On to Part Three.
