I've got a piece of stainless sheet that is 16 guage and want to cut it into 6 x 6 inch pieces. I have cut-off discs for my 5 & 4.5 inch grinders along with band saws and jig-saw. No plasma. Have used cut-off blades in grinder but leaves a rough edge, kind of crude. Would like a Beverly shear but can't afford one. Anyone have any idea how I can make cuts with the limited tools as described above? Pieces used for practice tig welding corner and butt welding. Best Bob
Reply:Go to a sheet metal shop and have it sheared. It's dirt cheap for what you are asking for.
Reply:A circular saw and a $30 metal-cutting blade will do it.Here's where I was shortening a steel cabinet. Here's the bottom section of a cabinet that I was combining with another:Freud makes a 7-1/4" blade that's designed for 1/8" thick and under mild steel. But I'm sure it would be fine with 16-gauge stainless -- maybe a slightly shorter lifespan because of the hardness. Here's a video of the same saw and blade cutting 3/16" plate:Last edited by Jack Olsen; 01-01-2013 at 12:55 PM.Jack OlsenMy garage website
Reply:Can you take it some place and have them shear it? Maybe a good excuse to buy a plate saw?http://www.milwaukeetool.com/tools/s...ng-saw/6370-20Or a nibbler?http://www.milwaukeetool.com/tools/m...e-nibbler/6880If you go the jigsaw route... you'll need a saw that can be slowed down. A normal wood saw at high speed will burn metal cutting blades in short order. Most are variable speed so dial the speed way down and it will cut better and blades will last longer. Use this guide to help select the correct blades:http://www.virginia.edu/art/studio/s...wbladechrt.pdfUnless your band saw is a large metal cutting saw... doing stainless on the band saw will not generally work. Like the jigsaw, you need to slow the blade down when cutting metal, especially stainless. Generally you need to be less than 100 fpm. The abrasive cut off wheel does work although it's slow and messy. I'd make a carriage and guide if I was cutting sheets rather than free handing it.
Reply:Thanks for your reply's. Didn't know a metal cutting saw blade would cut such thin metal. Learned something today! Thanks again. Best Bob
Reply:I got the advice here on the circular saw blade. I've used it on 16ga cold rolled steel salvaged fire alarm panel cabinets to cut 1 1/2" or so wide strips then to about 6" long practice coupons.Works great, but wear the face shield those chips go everywhere and ricochet at high velocity!Lincoln AC/DC 225/125 and WP17. 75A AC is for pipe thawing!HH 140 - new addtion 9/2012.I didn't agree, but hoped for Hope and Change.I got change for myself and my family: for the worse.This is the reality of: Barackalypse Now. Again.
Reply:Thanks guys, will go with the circular saw blade! Bob
Reply:Please let us know how it works. Stainless is harder than the blades are designed for, but 16-gauge is pretty thin stuff. I'm pretty sure it will work fine, but if it doesn't I'd like to know I was wrong.Jack OlsenMy garage website
Reply:Thanks guys for all your replies. I ordered a metal cutting circular saw, #8897-ozza shipped for $93.07. Also purchased thru Home Depot an Diablo Steel Demon blade for $38.49 as a replacement for the blade that comes with the saw when that fails. My existing circular saw is a Milwaukee and I did not want that messed up by the metal chips. I will report back here with my results within probably two weeks due to the not in stock item from Harbor Freight. Thanks again for your replies. Best Bob |
