Metal Cutting

[vmail]

Ive never worked with metal

I need to cut through Steel(not more than 2-3mm thick)

what tool could I use, hack saw is too bit to work with and I cant find the coping saw

I know what masonary drill bits look like, but how do I tell the difference between wood and metal drill bits

[Chappers]

Oxyacetalene (sp) (burning lamps)....have fun.

Use correct nozzle and settings...

Drill bits should be marked HSS, high speed steel..

[vmail]

cheers, might drill loads of holes the break it apart

[daktari]

2-3mm. What are you doing armour plating the yaris..... It`ll slow it down you know.

wooden drill bits have rings on the inside , to let you know how old they are.

drill loads of holes around the edge of what you're cutting, then knock out the hole and neaten the edges with a file or a dremil .

Old school classic

VMail, what exactly are you doing? U'll get a more specific answer then..

My old Dad gave me some very good advice -

if it ain't broke - don't fix it

if you don't know how to do it - don't do it

Both of which I think apply here.

[vmail]

thats what I was thinking of, how close should the holes be?

Ive managed to get a box for a fiver for the ITX PC, instead of paying 50-150quid

I need to cut a square for the the I/O backplare some holes for LEDs and switches

[Al J]

I'd just drill a line of holes (close together), then use a round file to open up the 'slot' then clean up the lines with a flat or triangular file.

It worked in metalwork at school!

2-3mm steel use a 'slicing disc', not a cutting disc in an angle grinder, slicing disks are 1-2mm thick depending on brand, cutting disks are 2-3mm thick. It will be like a hot knife through butter and is very controllable (just remember to watch both the front of the disk and the back of the disk at the same time)

Or get some long arm tin snips.

[Chappers]

I think he wants to cut a square, within a square..

[Al J]

Anyway... isn't this the sort of thing where you take it to "a man who can", preferably a mate who'll do it for a pint?

might give that a go if I can get the lid off the box, dont think we have a slicing disc, what would happen if I used a cutting disc?

dont have long arm tin snips, car I just put bars on the handles of the normal tin snips

Your best bet is definetly 'Chain Drilling'.

Drill the series of holes smaller than you actually require.

Then open up the apature with a course file.

Finally dress with a smoother file to get a perfect fit.+

Sorry, personally I dont think its safe for you to do it yourself Vmail. Might end up chopping hands off or something! On other hand.....

*joke*

[vmail]

thats not funny
