Trimming Corners

What's the best way to get a solid 90 degree corner on a flat glass job? I usually have 1" - 2" hanging over the edges (except on the factory cut edge of course) when I lay the film. What I do is stick the razor in the edge and then cut outward and make a slit towards the outer corner. Then cut the sides, but the corners still just don't end up "perfect" and at times look awful. However, if I cut the sides without making that slit in the corner, my cut is WAY off when it gets near that corner due to all of the bunched up film. Any suggestions?

try this method

Are you using a trimming tool or freehanding? There are some haters on the trimming tool but i like to use it myself, you really should leave a 1/16" edge anyway.

I have just started with the flat and I struggle with corners to. I do relief cuts most of the time.

When you cut your film out of the box, get it a little bit more precise!

Hacking off the corner at a 45 degree angle works really well too.

Also, just be gentle pushing it into the corner as to not crease it.

And always cut from the corner out. Never cut into the corner.

I like using a edge tool on some jobs, depending on the glazing type. I did a residential job the other day and for the corners I used the platinum ez reach tool used for auto. It is very small and fits easy in your apron, if you use one, and all I needed it to do for me was hold the film down in the corners, due to the corners trying to lift while cutting.

well said.

get a 5 way for sure....

5 way for me

Me too, big fella

Must be from another "old high horse vet" But WTF Do I Know

:WHO said to leave a gap? that is what the hard cards are for to "exit the h2o from edges, a customer told me some "company" said you have to leave a border for the heat to escape , and that is why they make film handlers so you can put a factory cut edge to the top and eliminate ( yes eliminate ) contamination.
thats the best tip tman,the diagonal cut... cut it close or you get a 45 on the corner

A certain company around me leaves a 3/8" (yes, three eighths inch) gap around all 4 sizes.



Must be to let the heat out.

Never mind all this bollocks about corners and gaps. Am I the only one who is besotted by tintzues's avatar ? what a pair of funbags

call a pro?

start trimming the sides that meet up with your factory edge... hence if you line up the top, start with trimming your sides, then trim the bottom. if overlay is only on one side compared to two, it will be easier and no relief cut will be needed. i dont use a 5 way but a hardcard. and i dont trim off of it, i use it to make sure my blade doesnt slip when cutting. i kinda "contain" my blade in between the card and the gasket

Well that leaves calling you out of the question then...

hahahaha

I use both a 5way and free hand it, it depends on the type of frame. For deep frames a 5way works well, and for cutting the edges I take the corner of the 5way and push the film in and then trim.
