Different way of cutting 45* frame

[Niki]

Good day

My name is niki, I live in Poland (after Israel and Japan) and I am an amateur.

I would like to share with you a different way (as far as I know), of cutting 45* frames.

Instead of messing with angles and protractors, I’m using a big, dedicated triangle.
The cutting method is “Left” and “Right” to overcome deviations from 45* and 90* (if any).

One important point.
I’m cutting the frame members to “final dimensions”, before cutting the 45*.
As you will see in the pictures, the triangle vertex is positioned at the center of the kerf, which means that, every cut will shorten the member by ½ a kerf width and, because we are cutting each member from both sides, each member will be shortened by 1 kerf width.
If you are using a 3 mm kerf blade, add 3mm to the “final dimensions” to get your planed dimensions after cutting.

The rest of the story, is on the pictures.

Regards
niki

Excellant tip Niki, thanks for sharing and welcome to the forum.

Your corner clamp guides look well thought out too.

Welcome to the forum Niki
Nice tip, one I am sure some will use

Thank you for the warm welcome and comments

I hope that this one and few other jigs and aids, that I’ll post in the future, will help a few amateurs like me.

Thanks again
niki

Niki, needing a mitre jig for my latest tissue box asp.

Your welded hold down clamps would be beyond my capabilities, any other mitre jig set up you can recommend?

Sorry John

The only alternate that I can think of is...Toggle Clamps...found some here, looks reasonable price...

Another alternate is to make it yourself as Peter (Sturdee) from "down there" made them...

Thanks again Niki (especially your quick response to help).

I have got a toggle clamp somewhere in my workshop, perhaps I can utilise it to do both sides. (on, off sort of action)

Pity Sydney is not next door.

Thanks for posting it. You did a great job and made this thread excellent. Specially with content you also post photos. It really helped to understand it batter and also with ease

Niki, hope this post does not cause any offence but I got over the problem of clamping by screwing waste end of timber to jig for each 45 degree mitre cut.
