Make aluminum strip

[Derbyboy]

How do I miter an aluminum strip for the best result?

I was thinking of mitering one like this at 45 degrees around the tiles by the fireplace. The tiles meet a floating laminate floor. The floor flexes a bit due to its shape, so I don't think a soft joint would work well.

Fine-toothed blade in the miter saw usually works well.

 

[Derbyboy]

How many think should I aim to have on the blade?

 

[Kane]

Depends on the diameter but at least 60 for 216 mm.

 

[Derbyboy]

My miter saw has a 250mm blade

 

[Kane]

Bosch has 80 teeth on their metal blades of 250-260 mm.

[AndersS]

A regular hacksaw and then tape the strip and draw the angle. Doesn't everyone have one of those lying around
And if needed, clean up with a file, but since you're cutting from the top side it usually turns out fine anyway.

 

[Derbyboy]

You'll need one of those boxes to get exactly 45 degrees and so that the saw has a stop.

 

[AndersS]

You'll probably need a box like that to get exactly 45 degrees and so the saw has a fence.

Nah, all squares have 45 degrees and I saw with the support of my thumb on such small moldings. Or if you're unsure, just knock together a box from three pieces of wood, enough with 20-30 cm long and width inside like the molding. Just saw 45 degrees in it with a miter saw, because you had that, and then follow one edge in it with the hacksaw.

Thanks!

If I feel that @AndersS freehand method gets too tricky for me and I choose to use a miter saw with a blade for aluminum?

which side should I have against the blade, i.e., upward?

should I tape the T-list?

 

[Lilllen]

I would turn the top side up. You shouldn't need tape. Lower the saw very slowly. Since the material in the trim is very thin, there's a risk that it might catch otherwise. I haven't cut such thin material in the miter saw, but if you clamp the trim between two pieces of wood on the underside and cut through everything, it probably reduces the risk of any catching. Keep in mind that it will create very fine aluminum shavings that get everywhere, so be in an easy-to-clean space.
