![]() ![]() In cutting 45's the blade will tend to pull the part in further, so watch out for that. Then make another cut, and leave the piece in the vise, this will enable you to mark the end of where the blade cuts, and scribe a deep line in the table, at a right angle to the end of the cut part.this will give you the point to meet when you stick the part in, and it will cut right every time.Īlso clamp it tight, but not so tight that is bends the vise.too tight can throw your degree off. Then make a cut, deburr it and check it to see if it is right on, assuming it is, (but if it isn't, make adjustments and repeat). You want to have perfect 45° cuts, so here are the steps to insure it.įirst, like Mac said use your speed square or similar 45° device, and set your saw vise to it. ![]() DennyĮveryone has made good suggestions.let me put it in a package for you. Try some different methods on some scrap to determine your best results. You may have to re-dress the disc several times if you have multiple cuts to make. Let the disc do the work and try not to "hog" cut your material with excessive force. This will reduce the effort of the blade to cut and try to maintain a very even light pressure. ![]() If you already have the thinnest, you could increase your reliability of angle cut by taking a wheel dressing brick and gently apply an angle dress on the disc to make the cutting edge like a knife blade. Other suggestions I will offer would be to get as thin an abrasive blade as you can. I like to do the 45 joints as they are much more asthetic. Since I use a dry cut saw, angle cutting on any of the square, round, rectangular & angle material is quite easy and very accurate. I use my combo square every time I make any changes, especially with odd angles. ![]() I will also concur with Mac regarding using a square to set the proper angle alignment of blade and vise jaws. Here is a good video by our own Rocky D that shows you how to cope the joint. If I want an angle, other than 90, I will make a jig. Once I got my cheap piece of junk HF chop saw set to 90 and cutting well, I figured that is pretty much where its gonna stay. It is much easier to fit it together and weld it nicely this way. I made the first cuts with the chop saw, then finish it with either my hack saw (if you don't have a lot to do) or a zip disc on the angle grinder. Oh yeah then, there was the few I cut 1/8" too short, but its all good learning. It took me a couple of hours to cope all the joints on some 1.5" angle iron I am building for my new Thunderbolt cart, but I have never done it before, and I had to watch the video a few times. It takes a bit longer than just hitting it with your chop saw, unless of course your chop saw is hard to adjust like my HF one is. The best thing to do is what I did today - Instead of mitering them, cope the joints. ![]()
