I made this simple but accurate jig for my table saw sled to cut some large (1 1/4”) boxjoints for a box that I am building .
It is one of those simple jig ideas that got made on the fly but produces excellent joints .
The jig consists of a melamine board that slides side to side along the fence and is retained by a couple of retainers made of plywood and solid wood .
A index block is attached to the fence face that is the size of the finger and a left and right stop block is clamped to the sled fence .
That is about all there is to it besides a material holder made of plywood and solid wood that is disposable .
Here are some pictures that I took of the simple process cutting the joints .
The jig with the stop blocks and index block.
The material holder in place .
The material in place one side and one front or back the long piece against the index block and the short pice offset by the size of the index block using a offcut pice that I used for the index block.
The boards clamped to the material carrier and also to the sliding fence .
The first cut with the sliding fence agaict the right stop (I am using a flat top blade )
The sliding fence against the left stop block and the second cut made and the waste in between is removed by slowly moving the sled forward and sliding the sliding fence side to side at the same time producing a nice flat finish.
The clamp that hold the material holder to the sliding fence is removed and the cut out of the board is slid over the index block and then the material holder is reclamped to the sliding fence ready for the next cutting sequence and this is repeated for as many times as requiered .
A very simple procedure and the clamping make for nice precise results and the little extra time it take is well worth it .
Here is the result of the dry fit and the box in my box clamp .
Joints are nice inside and out and when clamped in the jig and the box is square on all four corners .
All this took about two hours that is to make the jig and cut the joints ,as I said Easy .
