Trellis - all about it(?) Conclusion

This little beast was more work to build than anticipated, however the page has been turned. I thought I'd share some pictures of the assembly and installation.

I started with the lower tier of the trellis, fitting the battens into the central rib, and then one pair of legs with associated stretcher:


All the battens employ bare-face tenons on both ends.

On goes the other pair of legs and stretcher:


That completes the assembly of the lower portion. On to the top tier, again beginning with attachment of the individual battens to the central rib:


The remainder of the upper frame is brought together, and then entire assembly is plopped onto the four posts:


Time for some wedging on those post tenons:


Then trimmed flush:


With tenons on the posts now firmly attached, I moved on to putting the stubby shachi sen into place to lock up the corner joints:


The second one driven in completes the outer rod tenon connection:


Then the pins are trimmed:


Another corner - here's the site of the patch you saw in the first post in this thread:


A look at an inside corner, where there is also a rod tenon and a pair of 'parallelogram-shaped tapered wedging pins' (It is quicker to say shachi sen, yes?):


The connections drew up fairly well with the pins in place:


Another corner:


Another:


Considering I spent very little time fussing the fits of those joints, trying to complete the work as quickly as I could, they turned out decently I thought. I had planned on doing a separate beveled cap structure as well, but decided to pass on that plan. That might be a mistake, as I think the cap would have added considerable durability. That said, the cap can be added later if need be, so no worries. We'll see how the Jatobá hangs in there over the seasons.

The lower tier of trellis has a central beam fixed to the stretchers using double-wedged tenons:


The corner connections of post and stretcher, employing haunched half tenons and wedging:


The upper tier's central beam is attached using a 0.25" Ipé peg, and I did simple mason's miters at the meeting of upper arrises:


I used Jatobá for the wedges and shachi sen, and Ipé for the pins.

I gave the piece a quick an cursory swipe with the plane along the top and took the piece back to my house for the install. The two-tier trellis fit, as it was meant to, upon the Black Locust raised bed frame, now keeping 'tower of power' company:


Once screwed down with some stainless 2" screws, I dabbed some paint on bits of exposed end grain. It's done!

Here's a few more shots of the piece:



It's a climbing gym for plants:


It's nice to complete the main portion of garden construction for this year. I'm planning to pull the front axle out of my truck and rebuild it in the next week, so I wanted to get the trucking of pieces like this all wrapped up before I lose use of the vehicle.

The garden architecture is a bit of a laboratory for me. I can compare how Spanish Cedar, Teak, Jatobá and Black Locust stand up to the conditions, which in Westerm Mass orbit between well below zero and 0% humidity, to quite hot and 100% humidity. I have various different forms of connections and forms of making the attachments that can also be compared over time. It should be educational. I am looking forward to seeing the plants draped all over the two trellises later in the summer and will post up a pic or two so you can see too. This is all a big experiment I guess, as growing cukes, melons and squash on a trellis is not commonly done I don't think.  I'm a novice gardener so it's all about learning from experience here.

Thanks for coming by the Carpentry Way.

Trellis - all about it(?) Part Three

Moving thing along with the tale of a grille gone mad. Things are, uh, starting to mesh perhaps.

Today was a day of fitting, initially envisioned as a couple of hours, not a day. Funny how things stretch out sometimes, however I had some visitors to the shop and well, you know.

Here's the frame at this juncture, with the top conglomeration of beams placed loosely ont top of the posts:


As you can see the 'peace' sections at the corners, detailed in the previous post, those detachable and certainly not detestable nose pieces, are now trimmed to length to match their partners.

Here's one connection after trimming to close up the fit:


Any remaining sukima (gaps) in the joint will be squeezed out once the pins are driven in to drive the joint more firmly together.

Next, a view from the inside corner of the above shown joint, where you can clearly see one of the rod tenons and the twin mortises for the wedged fixing pins, or shachi sen:


Outside corner shows the other rod tenon:


The tusk tenon for the middle joist came out cleanly, though if I had spent a few more minutes planning ahead, I would have opted to make the joint with a mitered stub tenon on top like the corner joints have:


Exterior view of the same joint - then tenon is a little long at the moment and probably will be trimmed back a bit:


Another corner after fitting up:


Another corner:


And last corner for good measure:


I've marked out the upper framework for the mortises which will contain the smaller grille bars, and that work shouldn't take too long to complete. Then I need to do something similar for the lower tier of the trellis. I'm hoping one more day should see it finished, and we'll see how that goes. Thanks for coming by the Carpentry Way and hope you weekend is going as you would like it.  On to the conclusion.

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.

Trellis - all about it(?)

Final piece of 'architecture' for the garden is now underway, a tiered trellis. Unlike tower of power, this piece does not feature battered (compound-sloped) posts. It has its points of interest however, and like the other bits I've made over the past few weeks as we establish our new garden, it is made using joinery.

One little cut-out glitch today required a patch - here, I'm starting to clean it off:


After planing was done in the curly Jatoba zone of patchiness, it seemed altogether more presentable:


The plane, while not totally sharp, did its work:


Curly Jatoba was not part of the plan (not that there is much of a plan with these pieces), however I ran out of Teak and Spanish Cedar scraps of adequate length for this portion of the frame, and Jatoba is a lot cheaper than Ipé, and - most helpfully - available to me locally. I was surprised after jointing and planing to see that a couple of pieces were curly, something I had not seen in Jatoba before. It would have been nice to save it for another project, but that would have required another trip to the hardwood dealer and more money, so I decided to go ahead with it. Fancier than it needs to be? Yes.

A few shots of the various joints in progress on this trellis to, possibly, just maybe, whet your appetite, pique your interest, even titillate:


Haunched tenons:


Through tenons, which are a bit long at the moment and will be trimmed back:


Teak always looks so cool with all its variegation when freshly cut, but alas after a few weeks it all looks the same color. You know, that teak color.

What's going on here?:


The trellis is coming together decently so far, and I'm not fussing the details, just knocking the bits together about as fast as I can do the cut out. This trellis is for cucumbers and maybe some squash, so in a few months it will look much like a big green leafy cube in the garden.

By the way, did the pun in the post title work for you? I'm trying.

Thanks for dropping by, and hope to see you again on your travels in and around the interweb.Oh, and here's Part Two
