The cutter blade on my box blade is worn down to where it needs some attention but the company that made the box blade doesn't sell the replaceable cutter blades and, if I buy one from someone else, not only will it be expensive, i'll need to drill new holes. A friend suggested I use a hard rod and edge harden the existing cutter blade. Can someone please explain how this is done, what sort of rod I should use and any special techniques required to do it.
Reply:Hard facing rods work great and are not really hard to use. There are 3 basic typea or rod. Abrasion resistant, Imact reststance, And metal to metal. If you contact your local LWS they will have them. As a cutter you would need the AR rods. Some companys sugest a base rod som dont. If they do get them and the welding will go a lot better. If not use a 7018 as a base rod to build up and bad spots and then cover with the hard rods. Dont over weld to much as they are very hard to grind. The weld will look crapy usualy but dont wory all you are dong is leaving a deposit on the surface. Also check the voltage type be it ac ac/dc or dc becaus thay are diferent and will barly weld at all. One last rambaling thought most hard rods like a very long arc length so experiment around and find the best setup. Goog luck and at least try one Steel Thunder Welding LLC.
