Reply:You're going to have to give more specifics on what you need done. Lengths, quantities, time frame, etc. Put up your location too, maybe even a zip code so people can calculate shipping.

Reply:How about use a circular saw & use a guide to keep the saw lined up
Reply:I had that same thought, but since he's working with aluminum I thought a typical cut-off blade in a circ saw might clog up with aluminum too quickly. Do they make those for aluminum? It would be a good solution, particularly for a "it only has to work once" type of application.
Reply:You can cut aluminum with a circular saw with a carbide tipped blade. You will want to use hearing protection.

Reply:I cut down aluminum sheets using a worm drive skilsaw. Make yourself a saw guide, my dad, the carpenter, calls this style guide a "wonder board". I have an 8' length guide and a 4' and it's handy. I made mine from melamine covered particle board. Start with a 8" width and a 3" width (adjust depending on saw). Screw and glue the narrow board to the wide board down one edge. Once dry run the saw down the guide so it's dead on. Now clamp your guide board to the sheet material at your cut line. Your cuts will be dead on and your material will not get scratch by the saw because the saw runs on the guide. I find the worm drive works best as the motor doesn't ride on the guide when doing thick material. Any carbide blade will work.As others mentioned, it's LOUD and hot. I wear my safety glassed with a face shield, my leather welding jacket (snapped up, including wrists), and hearing protection.

Reply:Fascinating! I've used a 4' level as a rip fence and I REALLY dig your ideer! No more measuring for the offset to the blade and the kerf, NOR "living/dealing with" surface scratches. I don't know why it never occurred to me to do this. Sometimes the most obvious sh!t isn't so obvious.

The $89 Rage saw from Lowe's loves chewing up aluminum, and the swarf is on the hot side when wearing short sleeves.

Reply:I've used a guide like Forhire describes for years to cut sheet goods. I've got several of these as each saw is a bit different. I also set the guide up so I can cut on either side of the saw. I simply make a pass down both sides in the same direction. Given a choice, I prefer to use the side where the saw rides mostly on the guide vs using the side where I have to "carry" the saw, but that doesn't always work. I've even set them up on occasion to cut bevels, but you have to keep the saw in contact with the guide 100% of the time or it messes things up big time. The other thing is you have to remember if cutting bevels is that you are measuring to the outside point if the material is past the guide, and to the inside point if the material is under the guide.Also remember you always loose the blade width with these guides. If you can see it, you'll loose a blade width. If it's hidden under the guide, it stays. My helper always forgot this. He'd measure and mark, then toss the guide down any old way and cut. Most of the time he'd end up a blade width short, especially if he was trying to make long thin cuts and the good piece was hanging off the guide and the guide was sitting on the "scrap"..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan

Reply:Run that masonite/melamine with the slick side up is good also. Saw slides good, and the tpyical masonite backside is a bit grippy and sticks down a bit better. If you do a bunch of bevel work, set up some separate boards for thatExperience is something you get right after you need it

Reply:Harbor Freight sells a "Clamp and Cut edge guide" in two sizes. Might werk great as a saw guide. BTW, on the carbide tipped blade, they work great too, get the closest tooth count you can afford. There's a wax like blade dressing, can't remember the name,,, good stuff to preserve blade and make smoother cuts.

Reply:I cut sheet aluminum with a table saw and circular saw all the time. While they do make non-ferrous blades, all you really need for a few cuts is any 'triple chip grind' blade (use a 'laminate' blade).I keep both of these set up to cut aluminum all the time...

I get this blade from HD, but you can also get Onsrud non-ferrous blades online.
