Regards David > just got in from scrap yard I got a 26 inch square by 1.6mm bit ot stainless > > what sort ?? but the question is how do i cut it angle grinder or jig saw > any sugestions would help. > > Regards David Slowly with a lot of coolant / lubricant if your going with the jigsaw idea <eek> Personally I'd go with the angle grinder for quick, effective and cheap method. Laser, for the neater more expensive approach !

The methods of choice would be Laser or Plasma cutters. Pete S. > The methods of choice would be Laser or Plasma cutters. agreed but I looked in the tool box and only found an angle grinder and a hack saw. :-) I am not sure how much a plasma cutter would be , or how often I would want to use one. so the second option is the angle grinder.! Im only trying to make two plates to clamp something together with. It is outside so I dont want it to rust. But thanks for reply Regards David >Im only trying to make two plates to clamp something together with. It is >outside so I dont want it to rust. You do want to make sure you keep it away from contact with mild steel, otherwise that can cause local spots of contamination that will start it corroding. Don't angle-grind mild steel anywhere near it and don't use a saw blade that you have previously used on mild steel.

Ohhh, the hack saw, the hack saw, go on... but get someone to take pictures, I want to see this... *evil grin* Al. This is what the professionals use: Get a 4" angle grinder and fit a real proper (brand new unused) silicon carbide (not aluminium oxide) cutting disc in it. They are designed to cut on the edge and not the face. I chopped of a 3mm thick bottom of a stainless steel conical hopper with one (about 1.5m diameter) and it took 20 mins and took 3 discs. No lubricant required, quick as you like. Make sure you wear thick overalls, gloves and a full face shield (not just safety glasses) as sparks go every bloody where, especially for some reason straight down your neck. Much quicker than a hacksaw, jigsaw or angle grinder with a standard stone in it. Your local B&Q will never have heard of them- you will need to get some from a local engineering tool merchants. If you don't have one near to you, try Cromwell Tools (0115 9223311) or J&L Industrial Supplies www.jlindustrial.co.uk (0800 663355). RS Components also supply them (free delivery) rswww.com or 01536 201201. They are 1.02 each (plus VAT) and come in packs of 5 for a Norton BDX C grade silicon carbide 100 dia x 2.5 thk. Stock code 342-0902. Any other quizzes of an engineering nature, just post 'em up and I'll sort them out.

LOL, I think he's looking for a cheap and simple "out of the toolbox" idea. Hunting for diamond / carbide blades when you don't know exactly what your after is a bit off the mark. If the David hires these types of tools and gets it wrong then for every mm of worn blade tip, it's something like a TENNER !!!! in hire charges. best to stick with 99 pence angle grinding discs from the local market ! all IMHO of course. :-) SignatureAndy C (aka Fuzz) Always in it, Just the depth that varies. http://home.clara.net/andy.c/index.html Hang on, I'm sure the message said the discs are a quid(ish) from RS somewhere in there... and they will fit your standard 4" hand angle grinder in your toolbox. Dont use diamond either- too expensive and they clog too easily. Standard stones are crap for stainless- they take way too long. If you want a cheap source of stainless then go down to your local laser cutting company (we have 5 round here) and ask if you can ferret in their scrap bin. Take a magnet so you can tell if it's stainless or just shiny carbon steel. Also make sure you tell them that you're not a bloody pikey as they are always trying to scrounge stainless. Or lay nicked tarmac on your driveway. Lucky heather, anyone? >> This is what the professionals use: >> [quoted text clipped - 27 lines] >best to stick with 99 pence angle grinding discs from the local market ! >all IMHO of course. :-) |
