Just finished my new base.

Post by joebananas10 » Thu Dec 31, 2015 8:10 am

I finished my new base tonight. I replaced the 2 pieces of mdf with a single sheet of 3/4" plywood, then added five Shop Fox D2724 24-Inch T-Slot Tracks. I'm gonna give it a try tomorrow.

Looks good!
Just picked up a sheet of 3/4 MDF and was thinking of doing something similar.

Great idea. I have considered doing something similar. I look forward to hearing how it works out!

Joe,

Looks nice! Exactly what I was getting ready to do, except I am planning on using T-Track from Rockler.

What did you do below the rails and V-Wheels, rout the 3/4" ply back to 1/2" to allow clearance? Any reason in particular you used ply? I'm trying to decide between Baltic birch ply or MDF.

Exactly, I routed it down to 1/2". I used the plywood because I had a nice looking scrap piece lying around that fit the job.

I just picked up some T-track from Orange Aluminum and have been considering the same issues. Ply would certainly be better than MDF for holding the t-track screws. OTOH MDF is much flatter.

My worry about ply is - because it isn't as flat as MDF - I'd have to start every job by tramming the surface of the workpiece. :(

Or am I wrong?

Another issue - in this arrangement with the T-tracks in the baseboard, I assume I'll have to clamp the workpiece and a piece of wasteboard (e.g. 1/4" MDF) to the baseboard if the job cuts all the way through the workpiece anywhere. Right?

MDF would be fine if you ran the t-track mounting screws all the way thru as i did. I have nuts and washers on the bottom side to hold the t-track securely. I just like the look of plywood better than MDF.

My plywood was pretty flat but I do use a thin piece of waste MDF and that takes care of both of those issues. Also, as a precaution, when I'm cutting through the workpiece I zero my tool to the bottom of the workpiece instead of the top. That way if and when I do cut into the wasteboard it's very minor but in most cases it rarely touches it.

If I were to make another one I wouldn't put a track down the middle. I'd add a sixth and space them all so the two in the middle would go along the sides of the middle under-carriage bar.

I used a double thickness of 3/4 MDF glued together and just ran machine screws into it. Of course with the stock base you lose a bunch of clearance that way.

As for machining into the waste board, just put a piece of 1/4 or 1/2 MDF under the workpiece and mill into that. No reason your work piece needs to sit right on the waste board...
