    Default How to score 2.4mm stainless sheet prior to bending

    Hi all,

    I have some 2.4mm sheet metal about a metre long that i need to bend but I don't have bender, so I will need to score it then try and bend it.

    Is there another way to do the job ? and is there such a thing as a scorer or attachment for a grinder to do the scoring ?

    Thanks

    Chela

    Sounds like you want to partially cut through the sheet so it will bend along the area of thinned metal. I don't know of any tools that will do this with the accuracy needed on 2.4mm sheet, you would have to have fairly good control of a grinder with cutting disc to do this!

    The issue is you are trying to work with a material that you don't have the equipment to handle and without the proper gear it is very hard to work with these materials. for small jobs you will be lucky to find a fabrication shop that will help.

    There should be someone in Sydney with a pan brake folder on this forum that can help you out! I know of a few in home workshops around here!

    I'm with Stringy, I would not attempt to try and bend 2.4mm s/s, especially if the bend is a metre long.

    I would advise you seek out a fabrication shop, and ask them to do it.

    Stainless is pretty tough stuff.

    You can do it with a thin wheel on an angle grinder. I've done it with steel, not stainless and it was a lot thinner than 2.4. Under 1 I reckon. It's not that hard to control the depth, you just need to use a steady speed and pressure. Light pressure and repeated passes is my suggestion, with frequent checks in between. I was freehanding, but if you rigged a straight edge to guide the grinder it would be better.

    PS: Plenty of guys here know about sheetmetal so I'd take their advice. Like I said, mine was way thinner and softer.

    Thanks Guys,

    I'll take your advice and start looking through the yellow pages, just hope there is a place that will take on a small job.
