Played with the tracks again today.
Got the one side cut out yesterday so today I’ll get the other side done and start drilling for dowels.
Here’s what needs done and the jig to get er done.

More of the same but I will point out that I will be cutting grooves in the walnut and some of the mahogany now
just for this set but will need to set it all up all over again later for another walnut set so I’m making a cutting board.

With this I will be able to just set the board over the saw blade slide the fence over and start cutting.
All the figuring has been done why do it again.
I don’t have a Dado set, well I do but they won’t work with this saw so have to make a cut move over a tad and make another cut. Not as good as a dado but it gets er done.
I’m on the out look of a Shop Smith real cheap so when I do my dadoing will be on that.
Not getting the SS for the table saw want it for the drill press and lathe.

Made a simple jig to drill all those those holes.

I only buggered up three parts when the drill bit wandered off on it’s own. grrrrr!
But I’m only half done with the drilling so we’ll see.
Walnut wasn’t the problem it’s that soft mahogany that liked to walk about.

That’s all there is.
Thanks for checking it out.

About drilling: Your drill is much too long. Shorten (on the back side) your drill to prevent wandering. Or even better pre drill it with this cheap center drill:

Pre drilling looks double work, but I can assure you it is not. Downside is that you stay longer in the shop.. Benefit of pre drilling is that the mounting process will be much more convenient.

Success.

Dutch one more of many questions. lol
When you start drilling the other side do you drill all the way through or half and half to help it stay true?
Thanks in advance and for all your other help as well.

I do not drill all the way through, not even half and half. In your case I would drill a maximum of 8-10 mm deep in the blind side (male side) I also drill the two lips (female side) from both sides. This means that I use two dowels per track. One side of the dowel is always with a spearhead. When the dowel is 2,5 mm I drill 2,5 diameter in the lips (female) and 3 mm in the blind (male) side. I didn,t use glue. The dowels are pressed in and holds from it’s own. Sometimes you have to use a drill from 2,4 mm for dowels from 2,5 mm. The dowels I used where theeth pics with means that measerment isn’t that good.

Thanks Dutchy!!!
I don’t know why but I hadn’t even considered drilling just for the one side of the track when doing the male side.
Man I’m glad I started on the female side and with them I did drill one side then flipped it over. Thank you thank you very much.

Your welcome. My first thought was also do drill in once. It was Dee1 that give me the advise to drill from both sides.

I read on another site that it is recommended to use a denser wood for tracks so any one just getting started may want to keep this in mind.
The drill bit wants to follow any softer wood grain and will deflect the drill bit out of it’s needed path and bugger up the part..
That’s why they say when your making treads to plan on making 70 when you really only need 55-58 treads.
That’s my $.02
