The saw worked great! Cut straight and didn't seem to have a problem getting through the steel, but the blades didn't last long. The teeth on the blades seem too just strip right off the blade after a couple dozen cuts.
I thought right off the bat it was poor quality blades. So I went to Fastnal and bought 18 tooth Lenox bimetal blades and they work great. I know I have at least 4 times the cuts on one of the 18 tooth blade then the tooth blades. So it seems that the correct toothed blades seems to matter more with a Portaband. If you need some down to earth info on blades from an expert contact Tom at Blue Ribbon Abrasives. Grinding wheels, abrasive belts and discs, and other specialty tools from Blue Ribbon Abrasives.
With a portaband when your blade is coarser than optimal less than 3 teeth in the cut at one time you can angle the blade to the work so the work appears thicker. Also, when using too coarse of a blade, use a very gentle feed. When using too fine a blade, make sure the chips are clearing and not jamming in the gullets and make sure the blade isn't getting hot.
Thats what was strange. The cuts seemed like everything was going good. The blade wasn't getting hot, the chips weren't blue, seemed like it was cutting good. I wasn't really pushing or forcing the saw either. It seemed like it started in one spot about an 1" long where the teeth stripped off, then took more teeth off the more cuts I made.
Anyway, the 18 tooth blades are working great. I use a Milwaukee portable saw extensively for many years now cutting thinwall conduit, angle iron and structural shapes. The biggest factor in blade life on a portable is quality, I've tried every blade manufacturer out there over the years.
Lenox Bi Metal is the one to get, is the one I use for most everything. I stock finer pitches for really delicate items but almost never need them. If the Lenox binds in a cut it will pop off of the wheels before the teeth strip off, not so much for the others. Bennett says most standard woodworking tools can be used to cut and shape aluminum, including a cutting plotter and table saw. How fast should a bandsaw run?
A typical band saw speed is around one thousand feet per minute. Wood can be cut efficiently at much higher speeds, up to over 5, feet per minute, but you should keep it slower as it is safer.
How do I choose a bandsaw blade? Use larger teeth 2 or 3 TPI to cut and cut thicker material. A 6 to 8 TPI series knife will work well. Can you cut aluminum with a cold saw? You should be able to cut aluminum with no problem if you have the right blade and sharpen it on the blade.
Both grinding services above can customize the grinding for non-ferrous metals or steel. I had a non-ferrous cold saw with 14 carbide blades. What is a TPI blade? The number of teeth per inch TPI , along with the size of the esophagus and the width and depth of the space between the teeth will determine which material the blade can cut. Low TPI blades allow for faster cuts with rougher edges and are ideal for cutting wood. What is a saw blade? A chainsaw is a big one Bandsaw optimized for cutting wood along the grain to cut larger sections into smaller sections or veneers.
The frame is not very rigid and tends to flex when cutting. With the removable side being fixed by quarter turn fasteners it gives no strength. I have drilled in a few places and fitted bolts and wing nuts to clamp the whole lot together, effectively turning the narrow U channel at the back into a box section. It is now much more rigid. Replaced the sliding cutting guide with a home-made one in the form of a T-square with clamp for more accurate rutting.
