Jax Design: Spline jig with an adjustment stop

This is an easy to make jig and gives me really accurate
and interesting cuts. I do have a couple other sleds but
none like this. Here is a step by step on how I made it.

Here is my Spline cutting jig I designed in July 2014. It was made

very simply by using a piece of 2x4, piece of plywood and a runner.

The stop block I made slid along the top and was clamped into

position. This is worked very nice but I thought I would like to

make an adjustable stop block and upgrade this jig.

I will start by making a rail that will be attached to the front

base of the sled.

The sled is turned over and the rail is attached to the sled, first

drilled then countersunk and screwed together.

Baltic birch is used to make a block which will slide on the rail...

I use my miter gauge to cut the pieces. The sandpaper
holds the wood firm giving me exact clean cuts.

The blocks are tested for fit and ready to be glued
together.

Everything fits nicely and slides along the rail.

A strip is added to the block that will ride on the top
of the v-track.

The blocks are drilled to fit a threaded rod.

A T-nut is installed on this end for the rod, this will
move the block when the rod is turned.

Nuts are put on the right side. There is two on each
side of the block and tightened having a locking effect
so the rod will turn freely in the hole.

A handle is made using a wheel and a dowel. The dowel
is drilled and a nut and bolt are used so the dowel spins
freely.

I test a piece using a scrap 2x2 and am happy with the results.

Some are cut at 45 degrees and some at 90. I also sampled different

spacing.

Now I will make a small box, I cut
some 3/8" Baltic birch and cut them
at 45 degrees.

Glue is spread on the four pieces and tape is
used to hold it together.

Waiting for the glue to dry.........

The cuts were easy to make and I did not have to
clamp anything. After I cut four sides I turned the
handle 8 times and cut again. This was done 7 times.
