Good day

I would like to share with you the way that I cut frame members to 45° for frame.

Instead of messing with angles, I used big drafting triangle.

To overcome any small deviations from 45° or 90° of the blade, I'm using the Left and Right cutting method.

I cut all the members to "Final dimensions" (see Note) and the stop is positioned at the front to eliminates the need for long fences or pencil lines.

Note: because the stop is located at the front, every cut will decrease the frame member length by ½ kerf width, and because we are cutting every member from both sides, it will be shorten by one kerf width.
If you are using a 1/8" kerf blade, add 1/8" to the "Final dimension" of each member to get your planned dimension after cutting.

At the end, I added 2 pics of the new version with the plywood triangle and hold down clamps.

On the last pic, you can see how I made the hold down clamp:
Take a clamp, remove the fixed jaw, weld it to an iron angle, drill 2 holes and screw it on whatever you want.

Happy New Year

All over the world you can hear the sound of slapped heads followed by the exclamation, "why did'nt I think of that?".....

Again, well done Niki!

I'm not sure, but I think Niki is a stockholder in the world's largest drafting triangle manufacturer. :D Trying to boost the stock price through the sale of these triangles used in his many creations. :D

Seriously, looks good Niki.

I just wanted to comment on this sled.
I'm in the process of making a mantle/shelf surround for a double-sided fireplace. The top shelf will essentially be a frame. No big deal except that it's 72" long and 42" wide at long sections of the miters. I thought I would be able to get the job done with my radial arm saw as it has a 10' long table and can be adjusted for pinpoint accuracy. It would also allow me to set up a stop to insure duplicate lengths. The only problem is the tops will be 11" wide maple, which means the travel for the blade would have to be around 15" at a 45* angle. Mine only will travel 12.75".
I made the sled Niki described, complete with welded clamps and it performs flawlessly.
Just wanted to pass it along that if you have wide stock and need to miter it, this sled is the ticket.
Thanks for the idea and the photos...you saved my butt.
