Thank you so much! This is the problem I've been having and I'm proud to see that I was thinking correctly and I've already done everything you suggested, but what I was missing was the alignment step at the end, that was really helpful.

I'm going to have to give this a try. Just got my Mk 4 saw. I can't tension a blade hardly at all without one side or the other popping out of the clamp.

This saw frame drives me nuts. I run into this problem EVERY time I change a blade, and changing blades is at least a 15 minute endeavor. Not to mention the amounts of canned air I have to keep on hand. ARGH!

HI Johanna, Sorry you're having trouble. Why don't you drop me a line directly at info@knewconcepts.com, and we'll see if we can't figure out what the problem is. Changing the blades isn't normally that much of a pain, so something's wrong. Let's try to figure out what. Regards, Brian Meek, Knew Concepts.

Same…

Thanks again for the reply. 5" fret saw is what I'll need. Just one last question, is there any reason to consider the mark III, or should I just go for the latest version?

I have a scroll saw that uses pinless blades, and I have a large selection of those blades. I like the MK4 as it has clamps for pinless blades. But, I don't find how large the blade can be before it won't go in the clamping hole? What is that size and is there a difference between the MK4 and titanium?

HI Mark, The hole in the throat of the clamp is .073". I'm not sure what that translates to in sawblade numbers, but if the blade's smaller than .070" you're good. The titanium saws have better torsional rigidity and a resonance frequency so high it might as well be non-existent. Which mostly matters for the very thinnest 8/0 and 10/0 blades.

@@KnewConcepts Thanks, Just checked my blades, largest is about .058", so shouldn't be an issue.

I bought this saw from Rio Grande and it came mounted with a saw blade already in it. I am trying to unscrew the gold clamps and literally can't budge them. I HATE this saw at this point. How am I supposed to change my blade? I can't use pliers or it will damage the metal on the clamps. Any advice because I am seriously HATING this saw. I am trying to do some work and was using my simple German saw that was working just fine, but thought I wanted to try my new saw.

Hey Brian, is the 5" aluminium one a good size to choose as a general use wood and metal saw? And what blades would you recommend that I can find in Europe? Thanks!

HI Nitsan, The 5" saw is definitely our best 'all around' size. As far as blades in Europe, I'd look for the Pegas line. They're made in Switzerland, so they *should* be available easily in Europe... Hope this helps. Brian Meek Knew Concepts.

Thanks for the reply Brian. Are there any reasons to get the MK IV 6-1/2" coping saw over the MK IV 5" saw? Is the coping saw made for tougher jobs? (steel, etc.) Or will the 5" do the same jobs just with tighter curves? Thanks!

HI Nitsan, The coping saw and fret saws are really different things. Coping saws cut faster, but can't turn nearly as quickly as the fret saws can. It's sort of like asking which is better, a car or a truck. They do different jobs, and depending on what you want to do, one is better than the other. Short form: coping saw: fast cuts, slower turns. Fret saw: tightest possible turns, everything else secondary.

HI Nitan, It depends on what you're doing. The Mk4's are stronger, and that becomes especially noticeable as the frames get deeper. (Which is why we don't make an 8" Mk3 any more. The Mk4 is 3x stiffer.) But they're heavier. Some people, especially jewelers, really like the lightness of the Mk3 frames, which is why we still make them. But that's a personal decision. It's entirely up to you. The strength difference in the 5" frame isn't *that* great. (45 pounds(Ish) versus 55-60 pounds. ) So, is up to you. Regards, Brian

Nothing to do. I did it all. Impossible to fix an 8/0 blade, was never possible, and now 3/0. I must definitely put my Knew concept aside for good!!! Very disappointed!!!!
