I'm looking to make or find a blade for a frame saw that has a cutting specification of 3 teeth per inch (TPI). Does anyone know how I can make one, or where I could purchase one besides Blackburn Tools?

To make your own blade, you might want to use .042" 1095 coil steel, which is a standard thickness. You'll need to get a strip about 4 feet long and 4 inches high. Mark the teeth every 3/8" for a pretty good result, which translates to around 2.67 TPI. I've been using a similar setup for a while, and it works great! Just keep in mind, filing the teeth can be a tough job that takes a couple of hours. Also, make sure the steel stock is flat and not rounded at the edges, as that can dull your files quickly. Good luck!
I got my blade from a user called Ok_Examination4602. It worked well for my frame saw setup, so you might check them out!
I've heard you can repurpose a band saw blade by cutting it down. However, the tooth design might differ since band saws are usually powered differently compared to hand-powered frame saws. I haven't tried this myself, so I’m curious if anyone has actual experience with it.
If you want to save some time sharpening, try hacksawing the depth first. You can use a broken hacksaw blade attached to a piece of scrap wood for consistency with spacing.
