man you blew my mind awesome idea thank you

Filing should only be done in forward direction. Bi-directional use dulls the file.

What type of punch center, line-up?

[@MAC-ez2rq]

This guys is a pro. Tnx for the tips.

[@petesmith9472]

Thank you. A lifetime hint right there.

[@Andrew-rc3vh]

I tend to do it so the holes are spaced just short of twice their diameter and then centre punch between them and drill.

Great video will this work for Brass as well I need to make a square in a 3/32 brass piece (2.38)mm

[@euphonic922]

what is used used to scribe the metal and tap the little dents?

[@GenePavlovsky]

A scriber and a center punch, respectively.

[@serfinusa9532]

i used a dremel

[@aerofart]

This is a fine method for rough work, but not very good for precise or clean work.

[@juliogonzo2718]

Ok, how would you have done it with hand tools?

[@BohumirZamecnik]

Thanks, I was looking how to make a half-open rectangle hole for a C-shape thick workpiece. The sides can be cut by hack saw but the inner edge needs to be drilled first.

[@comandornic440]

is it less than 2mm thick plate?

[@sureshlingabathina]

There must be easier way than this. It is 21st century for sake

[@anonymousarmadillo6589]

Use a laser or waterjet cutter.

[@chroma6947]

If you cant simply use a chisel+hammer and then sand the edges i dont think you should even bother. Its not hard. Unless you have a cnc machine this is the easiest way imo.

[@nighthawk6468]

You could always use a dremel, a cut-off wheel, and a steady hand.

[@GenePavlovsky]

@@nighthawk6468 I've done it with a dremel, and the chisel&file method can actually be faster and less annoying.

[@nighthawk6468]

@@GenePavlovsky Yeah for sure, though filing can get a little annoying after a while though!

[@wk961]

BRILLIANT!!!

[@Yuēhàn24]

For very thin sheet you can just use the chisel no need to drill first especially on thin aluminium. great video.

[@MrCPPG]

I need to do this to 1/4 inch thick aluminum. Do you think a chisel alone would work?
