Good day

I would like to share with you the way that I’m cutting frame members at 45°.

Instead of messing with angles and protractors, I used very accurate, dedicated triangle.

To compensate for very small deviations from 45° or 90° of the blade, I’m using the method of “Left” and “Right” cutting.

instead of locating the stop somewhere 3’ behind or relying on a pencil line, I’m using another same width piece to be used as “Limiter” or “Stop”.

One small problem with this set-up is:
The triangle vertex is at the center of the kerf, so, when you cut the 45°, the saw blade will cut half of the kerf width, from the length and because we are cutting each member from both sides, each member will be shorten by one kerf width that you have to take into account when you cut the members length to “Final Dimensions”.

In simple words, If you are using a 1/8” kerf blade and want the frame to be 20” x 20”, cut your members to 20-1/8”, the 1/8” will be removed during the 45° cutting.

If you remember the post “Triangle, copy and past”, later, I used one of them instead of the plastic triangle (last 2 pics)

Regards
niki

Thank you Niki -

The pictures really helped me understand how this is done. I had previously cut all miters by using the miter saw. I also used the right and left method. By using your type of jig, I feel it will be more accurate and easier to do. Thanks again.

Thank you for your kind words

I made this frame only for the example (just to take the pics), one day I will post a “real” project made of Oak.

Fred
It is very easy and accurate and because I know myself, I did not leave nothing to the chance…

Lou
You are so correct, 200 and more years ago they made beautiful furniture without the tools that we have today….and I wonder – how….

Thanks

that’s an interesting thought.. because, today, we have the tools and look at the quality of the stuff that we buy in the big stores…. shameful really. Our ancestors must be really disappointed.

Yeah, Niki, I think something is wrong with the photo setup.

I’m so sorry

All my old Photobucket album disappeared and I had to open new album…all the newer posts are from the new album.

I promise to upload any requested post pictures, just reply to the post something like “niki, upload the bloody pics” and I’ll get the massage :-)

Sorry for that
niki
