any ideas on this? I cannot afford a metal chop saw at the moment and am not getting very straight cuts with the angle grinder. I was thinking to make a device where I can clamp down my metal (small angle or tube steel) that has a guide I can run my grinder along to get a straight cutany one done this , have any pics?
Reply:I've done the straight edge method before works ok if ya don't cut into your straight edge. Use the thin cutoff wheels, which I think is 0.45. I normally then just follow my line. some people scor the line first then cut,but ive never had much luck with that. I just go for it, letting the cutoff wheel sort get on plain like a boat in the water ,letting the wheel do the work.
Reply:I've used the straight edge "guide" in some cases, but normally just free hand it. After you do enough of this you get decent. They do make a replacement guard that will fit on a 4 1/2" grinder with a shoe similar to what is on a circular saw that you can ride against a fence. This works great with diamond wheels on tile and such, but not so good with abrasive blades that wear down as you cut..No government ever voluntarily reduces itself in size.

Reply:Unless it's a very short cut, like your tubing and pipes you're talking about, I always score the cut first and then complete it. I don't use guides. Practice makes perfect - you have to be smooth and fluid, just like other processes that we deal with.What are you using to mark your material with? If you want accurate hand cuts, you need to toss your soapstone somewhere that you won't find it and use something like a silver pencil or thin-tipped sharpie depending on the material.Finally, if you're not using a full face shield for this, you need to get one and wear safety glasses inside of it. Then you won't be squinting so hard that you can't see the line you're trying to use.

Reply:score it once, let the wheel pull the grinder along the material and concentrate on getting the score straight. After that the wheel will follow the score and your cut will com out straight. On pipe, having a way to roll the pipe along the wheel for the score helps a lot, square tube I lay out straight lines on all 4 sides and score around the tube then start my cut at a corner, cut 2 sides from the same corner flip it over and cut the other 2.

Reply:I used a sidewinder skil saw for years, with just a 7 1/4" cutoff wheel. Just wear protection for your ears, eyes, lungs and fingers. Like anything, it takes practice to get precise. I've seen guys who can cut a piece of tube with a sawzall and you'd swear they used a chop saw, the cut was so straight. Go to HF and get a cheap chop saw. You just have to work within the limits of the machine, not expecting 4 hp performance out of a 2 hp machine. BTW, my Milwaukee super sawzall was made in Italy. Just sayin', don't want to start that debate up again.Contrary to popular opinion, I do NOT have a pet turkey that craps molten steel. It's a goose.

Reply:You will find that "wood" saws have exactly the same motors and the same rpm as "metal cutoff" saws.So, saw benches, radial arm saws, sidewinder saws, and all the rest work fine for us.And in the smaller sizes, are pretty useless for any serious wood butchery and often go really cheap secondhand **HINT**Cheers, Tony._________________________________Transmig 310 + Argoshield LightOxy acetyleneOxy propanePrehistoric stick welder_________________________________

LOLBut yeah, I may look into that as it sounds pretty handy.

Reply:I don't really have a suggestion as far as tools go. But my advice is to make sure you position yourself so as your comfortable as possible. I don't know your situation, surroundings, or skill level but I've seen many people struggling with a cut-off wheel because they're not holding their grinder properly or their work is not secured properly or sparks are flying back in their face etc. If it seems difficult your probably not doing it right.
Reply:you could live in ghetto neighborhoods where people get evicted all the time and score a free miter saw like I did a couple years ago. LOL..for once i actually listed to the wife and the neighbors across the street from where we lived got evicted and had a big pile of stuff sittin by the curb. among all the junk was a 10" ryobi miter saw and the wife said i should go grab it. I just figured it was some broken POS and was going to leave it there, glad I didnt because it works great and the price was right. I actually dont have a metal cutting blade on it yet, just havent had the need but since I just started welding i think that'll change soon. I usually use the angle grinder and a cutoff wheel but I cant cut a straight line to save my life so I cant help ya there.
Reply:If i have the time and it needs to be a tight fitup i do rough cuts with the angle grinder or portabandsaw and then dress it up with the disc sander.
