Cutting L-angle and feel stupid lol

Postby pavetim » Sat Mar 11, 2017 11:04 pm

Ok I have a chop saw and I can go 45 degrees one way. I am cutting L-angle at 45 degree cuts so i can join and weld but for the life of me after the first cut I can't figure how to make the matching cuts. I can't swap the angle as my chop saw only angles one way. The way i got first cut is put the angle in the clamp with the horizontal part in the saw, and the vertical part away from me towards the saw and then i cut. That's first cut.

You will need o flip the part end for end and then put one of the flats on the top. You will need a wood block the same thickness as your angle to suport it.
I have more questions than answers

Done this lots of times but had to think a bit at the start also. Maby easiest to cut a piece of angle a bit longer -cut the 45 0n 1 end -flip end to end so flat on top with vertical toward saw. Put piece of square stock under the angle at the vice area big enough to tighten in the vice to hold the angle secure. this will give you an "inside flange" corner . Once you see the concept you can try other variables " outside flange " etc. Clear as mud?? ;) :ugeek:

Yeah its a pain in the ass. But if you can only change angles one way you have to flip it end over end as the others have said.

Some times its easier with some scrap pieces to visualize which way you need to cut especially if it gets a bit complex.

Not my favorite thing, its like doing cornice, think you guys call it crown moulding.

You mean those you either by twice the estimated length or visit the lumber yard three times to finish the job :lol:

One tip that can save some time is simply to mark the approximate angle with a sharpie. At least you won't cut the wrong side and makes it easier to see how to clamp the piece.

Or for those of us w/o a chop saw clamp a straight edge (scrap piece of steel flat stock) at 45 degrees, and follow edge with a right angle grinder.

I was reading and said coping was better cause the welds aren't in the same line so should be stronger. Ill probably just cope it then. But thanks. Ill practice 45 angles for less structural stuff.

Ya gotta get back on the horse!! Remember if someone else can do it you can too! I looked up coping because I have never done it and looks like a lot of work for a mitred corner. As for strength maybe so but is that any advantage in your projects? When you want corners other than 90 degrees coping could get interesting. Do you know anyone who would give you a quick demo? " Pictures worth a thousand words ". A wise heavy equipment operator once told me--It takes but a short time to learn to run a machine but a lifetime to learn all it's uses! A good quality chop saw can be a very versatile tool. :ugeek:
