Since I use a 14" dry cut saw & 10" table saw to cut the majority of my metal, I use my saws daily and finally there comes the time that the blades need sharpening. I was taking them to work to have the fellow who sharpens our company blades do mine also. It was getting to the point of having to wait 3-4 weeks for a return and, at times, stopped production because we only had one for each saw, my boss allowed me to get 4 additional like my own Freud Diablo blades. Finally, I decided to look at the new Harbor Freight Blade Sharpener since they now have a HF store only 10 mi. from me. The website nomenclature for the unit was really brief & didn't specify all the parameters of the unit. When I went to the store to look at the unit, I was quite impressed with the workmanship & quality and features that weren't described on the website. It was on sale for 59.99.....I bought it.
When I got it home, I set it up in my machine shop next to my spoolwinder and read the owners manual several times to understand the setup. The manual, as most of the HF manuals, leaves a lot to be desired regarding proper & precise instructions. For me, it was quite simple and I had it set up & ready in a half hour. My old tool & die days helped me remember the proper technique for sharpening tungsten carbide. I took the blade(14") from the dry cut saw and got the alignment & stop assembly to the correct positioning & indexed the blade to each tooth to check for correct grind angle. When I was satisfied everything was correct, I proceeded to grind each tooth. WOW!!! It was it easy and each tooth came out perfectly. The rake was ok so I didn't have to grind the rake at all. They did furnish the xtra grinding wheel to do the rake, but I will set up another fixture to do that instead of constantly changing wheels to do each operation.
I put the blade back in the saw, put a piece of 2"(.125 wall) sq. tube in the vise & cut.... just like new again. I like the unit & believe it will quickly pay for itself since I have (6) 10" non-ferrous C-6 AL blades, (6) 10" ferrous C-7 blades, and (5) 14" ferrous C-7 blades. Attached are the photos of the setup. If anyone is contemplating resharpening their blades, this unit works great. Of course, familiarization & understanding tooth configurations will benefit your ability to get superb results. Also, take care and take your time to get the setup to the proper configuration for optimum results.
