I purchased some strips of 2 inch flat ... maybe 10 or 11 gauge?I have a mikita metal cutting chop saw that works great. I've cut lots of 6 inch "coupons" from the 10 foot strips of flat for 1st position welding practice but, now I need to work on fillet welds (GTAW) and I don't want to keep wasting the coupon when all I'm welding are the edges together. So, I'd like to cut the coupons vertically, lengthwise, in half. Make them skinnier. 1 inch or so.I don't think I can do that (safely) with the chopsaw. Do the horizontal band saws handle this type of cut well? I think it would be an easy cut for a vertical bandsaw .... but can someone chime in on a good solution worth buying if necessary?Also, I have a small wood shop - do vertical Grizzly and Jet bandsaws run slow enough and work ok for metal work or is it really necessary to wait and pick up a drake or something so much more awfully expensive ... I'd like some dual purpose if possible ... do Drake's run fast enough to cut wood?Just looking for suggestions - I'm not sure which I would or wouldn't want to look at ... but for right now, I'm just looking to cut some 2x6 "coupons".
Reply:I'd use six-inch cutting discs in a circular saw if you don't have a 6-inch angle grinder. Chop saw wheels are thick and the saw design is limiting.
Reply:That seems like a really good idea!Can I pick up any old circular saw for that - or do I need to look for a something special. I do understand that either way, I need a very specific blade.

Reply:The first thought that came to mind was, "Doesn't his supplier sell strip in 1" widths?"Mine sure does.If you're cutting 1" strips from sheet, an angle iron guide and steel cutting skilsaw (I use the Milwaukee 8" metal cut saw) does a great job.  I wouldn't use it for ripping 2" strip in half though.Syncro 250 DX Dynasty 200 DXMM 251 w/30A SG XMT 304 w/714 Feeder & Optima PulserHH187Dialarc 250 AC/DCHypertherm PM 1250Smith, Harris, Victor O/ASmith and Thermco Gas MixersAccess to a full fab shop with CNC Plasma, Water Jet, etc.
Reply:Weld one side of the coupon for a t joint, then break apart in a press, then use the other sides. Should get 8 fillet welds from 2 pieces of steel using all 4 edges on each plate

Reply:I think a plasma would be a great start.I have a Eastwood plasma.  Not the greatest, but fine for a hobby use.The way I cut with a plasma in high school was to clamp an piece of angle iorn, and run the torch against the angle.  Gives you an awsome cut if you learn how to use it and set it correctly.
Reply:Before I had proper cutting implements, I'd have ripped this thing with my chop saw.  I'd just feed it into the blad a few inches, then flip it over for the rest of the work.  I know, not the safest, but works in a   pinch.  I've ripped short sections (usually no longer than 6") of .065 2.5" and 3" OD tubing this way too, to make cradles for my various fixtures.  Have also used this method to make motor mounts from 3/16 plate.AaronJet 17.5" Drill Press1942 South Bend 16x84 Lathe1980s Miller 320A / BP --- 2013 Power Mig 2562012 Jet 7x12 Horizontal BandsawVictor O/A Setup
Reply:I'm with Sundown. For less than $10, go buy some 1" strips. That's less than the cost of blades, wheels, ER visits, cleaning up afterward, etc.Burt _____________________Miller Syncrowave 250Millermatic 211Miller 375 Plasma Cutter Hobart Handler 12010FtDrillBit.com

Yes, of course. But I already have 20 feet of 2" flat that was purchased last year. I'm just trying to make it go farther.> If you're cutting 1" strips from sheetAgree with Anvil ... good idea (for next time).@CamAus> Weld one side of the coupon for a t joint, then break apart in a pressI guess left out the part about "I dont' have a press" Thanks for the feedback ... seems like most are in agreement, a waste of energy to rip them down. It just feels wasteful.-Luther
