I have an older Craftsman hold down miter gauge

This threads shows the different miter gauges I have collected over a period of 50 years.


As far as the clamp down version goes, I still use it, but I have removed the hold down clamp. It was a bit of a pain, workable but annoying. I recommend using a clamp that secures the work to the extended fence rather than down towards the table to reduce and sliding friction. If you just extend the face of the miter gauge you have with a straight and flat 3/4" piece about 20" long that's what I use. I just replace mine a week ago because it had so many different cuts at different angles it looked all chewed up.

You can always make a dado near the top for a "T" track which allows you to clamp at any position OR make length "stops" for precision cuts of multiple pieces:

Some good ideas here, but this one makse 90 degree cuts only:

For longer boards, with no miters ........

The boards are 10" boards so my miter saw won't work. It's usually my go-to saw for most of my angle cuts, but I don't have
a sliding miter saw for this. Boo.


I had thought of this but I really wanted a 'one cut' solution. I thought perhaps the miter clamp would be just that. But:

Totally agree. So, I think the clamp idea is out and the fence idea is in. Thanks for the help and links!

Use two identical miter gauges for long boards. They will slide real easy when properly adjusted and remain at 90 degrees to the blade.

For longer boards with miters your only good solution is CSMS OR a radial Arm Saw. Wait.... you could always use and adjustable cross cut guide and a circular saw.



Apparently I have the only adjustable circ saw miter gauge on Google because nothing show up in a search not even DIY versions.
Mine is circa 1960's...... maybe a Craftsman? One could be made that's not adjustable, but to the desired angle.
