well i tried to grind out the shape of my first knife but the grinder is jacked up so i tried the jigsaw(eventhough i had been told it would not work) and guess what surprise to me it did not work its almost like it has been tried before. anyhow so now i am back to not knowing what to do but i think there is hope a guy at work said he has a Dayton bandsaw he will sell me for $75
sounds like a good deal to me but will a bandsaw cut the mustard in this case the mustard is 1/8 ats-34 and if not what do you folks use to cut out ya'lls designs? please any and all advice will be greatly appreciated.

thanks

Hi Josh, Is it a metal cutting bandsaw that he has for sale?

Wood and steel bandsaws run at different speeds. A metal bandsaw will cut wood well enough but a wood saw won't be all that great for steel.

Blade selection also plays an important part. I'd check what type it is first so you can make an informed decision.

Cheers

If it a wood cutting saw it won't work for the steel but still a good deal if it's in good shape.Better to get a Harbor Freight 4=1/2" angle grinder for about 20 bucks.I profiled a lot of blanks with mine before I got my steel cutting bandsaw.

Same here. I used a 4.5" angle grinder for several years. I used a metal-cutting disc to cut off the big chunks and then switched to a grinding wheel to finish out the profile. Once you get close, switch back to files to clean it up.

ok hwere do i find the cutting disc and should i worry about getting the metal to hot i know that if i grind for a long period of time that the metal in and around that spot will turn blue is this going to be a big deal? the bandsaw was supposedly bought from some guy that had a knife shop, the guy that has it now did not say if it was a metal cutting saw but he too makes knives mainly regular style folders with multiple blades, anyhow i will ask monday or try to at least. ah can i get the discs from home depot? i was in there the other day and looked at their selection of files i was kinda excited seeing that they were not way over priced i thought most of there nicholson files were under $9, oh ya this is going to take me longer than i thought becuase of my lack of tools and a shop but i think i can manage i will just have to figure something out but i will make it i suppose. well thanks for the insight on the bandsaw and the discs not to sound dumb but i was unaware about the different saws i new i would need a different blade but not the saw. glad you all mention that one.

thanks

Discs are fairly easy to come by at any hardware store (Lowes, Sears, Home Depot, etc.). They're in the same place you buy the grinding discs for the 4.5". Keep in mind that they make 4" angle grinders as well, so make sure you match your disc size to your grinder.

As for heating the metal, obviously keeping it cooler is better, but when heavy grinding with a grinding disc, you're really just burning steel off. It's going to discolor and turn past blue. Before heat treating, it's not going to make any significant difference.

I picked up a HUGE pack of 4" discs at harbor freight a couple weeks ago for 9.99
