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.

Peace, man:


 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.
