« Part 22: Found the plan I want to work from. Box joint jig build start! Part 23 of Upcoming projects and designs. series no next part

Tonight is a simple project, kind of…

I need box joint jigs, for 1/4”, 3/8” and 1/2”

The big issue is going to be getting the required pieces but, safely.

My thought process is to take several pieces of walnut scrap, plane them down to 1/4”, 3/8”, and 1/2” thick respectively, then rip them to width after sacrificing some scrap to make certain I have the width correct.

Once I have the indexing pins made the rest should be easy peasy, with one caveat.

My table saw is a Ryobi BT3100 with a sliding miter table. The miter fence on that isn’t like your usual miter gauge, I need to figure out a way to secure the jig to the fence. I figure going over and behind the fence in U fashion, and then using a threaded star knob / bolt / insert, and jam nut setup to tension to the fence should work… Not as neat and pretty as a regular miter fence… I do have slots on my saw, and after painstaking alignment, they are lined up. I might have to just grab a basic miter gauge for this function…

I guess it might be time to grab that Incra V27… And get to making boxes!

There is a t-channel in the miter fence you can use to attach jigs to. The trick will be finding compatable nuts that fit in the channel.

I made an adjustable box joint jig a few weeks ago it cuts joints from 1/4 to 1”. I used the plans from shop notes #8. It works great.

Don’t much about your saw, so don’t have any useful commentary.

My old Delta Contractor’s Saw in Anchorage is very standard, and with the Vega fence, super sled, and an Incra 1000HD, a recent purchase, I can usually make things work out. Here in La Conner I have the Rigid R4512. The fence that came with is not quite as good as the Vega, but it doesn’t need replacement. I picked up an inexpensive sled from Rockler, and have an Incra 1000HD here also. I tend to duplicate things at the two shops to minimize relearning things. Seems to be a lot of box joint jig plans out there, so I assume you will find something that will work.

I am putting 1/8” thick pine strips on the 3/4” plywood edges on my pedestals and torsion boxes today. They make up the parts of my torsion box bench. I was hoping to post it this trip, but I think it will be tough to get the trim done this week. I will probably finish it with Watco (what else…..(-: ........) when I can leave things outside to dry. Putting the pine trim on is worth it, because then there is no delamination of the veneer. The pine puts up with a lot more abuse than iron on edging, although I use that for non-shop objects.

So, will be interested to see what you come up with for a box joint jig…......

Stoli, I actually went ahead and ordered some T nuts, and star knobs from for this. FWIW, if you do order from them, please be sure that you list as the referrer…

I ill also head over to the hardware store and pick up a few 5/16-18 various length bolts, and make my own star knobs… I had fun making them for my jointer, why not for jigs?
