Title: Blades cutting like cutting butter.... :+}
Post by: Danny on November 27, 2011, 09:05:02 am: Bet all have thought about when a blade has gotten to dull....
Heres my two cents.... A NEW blade will cut like if you imagined cutting thru butter.... After time you Will notice that this easy cutting has gone away.
Or when you get to the point where your having to push the wood into the blade harder than when you started. I am sure I have been guilty of the as some projects I just wanted to get finished and kept on cutting even tho I knew it was time to change to a new blade. Anyway.... Danny :+}

Post by: Spartan scroller on November 27, 2011, 10:02:52 am: Me too Judy: I guess it's that natural "thriftyness" we have built into us. Get as much as we can out of what we've got. I just can't bring myself to throw away a blade that's still cutting. Then I reach a point where it breaks and I have to change blades and it cuts so nice that I wonder why I didn't do it sooner. Got to go now and start my scrolling for the day with a fresh new blade!

Post by: daliclimbs on November 27, 2011, 10:31:06 am: I do it too. I doubt there is anybody who isn't guilty. The benifits of switching blades is huge. Easy cutting, cleaner cuts.. but for some strange reason I always say, "just five more minutes and I will change".. that naturally turns into 30 minutes LOL..

Post by: dgman on November 27, 2011, 12:01:08 pm: Not me! As soon as it dulls, I finish the cut and change it. Sometimes I don't even wait ti finish the cut. If it is to dull to finish the cut, I will make a little "cut out" so I can easily fit a new blade in to finish. I don't save a blade for latter either, because latter never comes. Blades are cheap and time is money!

Post by: tux_linux on November 27, 2011, 12:59:42 pm: true - sometimes I forget about it too.
I cut and notice the extra pushing. But then O change entry holes and do not change the blade...

I mostly change when I switch to another item, but also not always....

Post by: Jim Finn on November 27, 2011, 06:00:59 pm: I only do inlays so I am cutting 3/4" of material ( Stacked 3/8" each). When the blade starts cutting slowly I change it out with a new blade. I save the old blades and cut off the bottom 3/4" of them with a tin snip and then I have a "new" blade, just shorter. My Hegner will adjust to this shorter blade. Will your saw?
Title: Re: Blades cutting like cutting butter.... :+}
Post by: tux_linux on November 27, 2011, 07:06:43 pm: Jim, that works? Isn't the saw going hard when the blade is like 3.5" or 4" ?
I noticed my Hegner to run smoother when the blade has not to much tension. So I expect this to run quite hard/steady.

Post by: GrayBeard on November 27, 2011, 07:29:52 pm: IF you are doing 'portraits' with SPIRAL blades you darn well better have a sharp blade in your clamps at all times!
If you have to 'push' the wood into the blade you risk the danger of a 'slip' which can cost you the whole thing...

I keep sharp blades and run the speed as fast as I can so that a VERY gentle touch is all I need to keep the blade on track and the wood moves as slowly as needed to make the detail cuts!

Happy "Portraiting" to you all....

Right now I am about 1/4 of the way through Grampa's "Big Cats" and have gone through 4 of the FD New Spiral 2/0 blades.

Post by: ChuckD on November 27, 2011, 11:49:37 pm: You know, there should be SOMETHING we could do with used blades beside discarding them. I was thinking of making a hedgehog but that didn't turn out. Kept getting poked.

Post by: Fab4 on November 28, 2011, 06:05:26 am: Changing blades????????
I always thought that you keep going until they break (lol)
At least that's how I started out -
Couldn't figure out why my cuts were angled, yet my table was level

Post by: Marcellarius on November 28, 2011, 08:48:36 am: although most times i start a new project with a new blade I'm using the blades to long as well.
I have a small tube were i keep my old blades so sometimes on tiny and small projects I use an old blade because the new ones are to aggressive.

I did so too, but lost control about the blade sizes of used blades in the last few weeks. I should organize the blades better.

Post by: Rapid Roger on November 28, 2011, 10:45:11 am: I have used the "crown tooth" style blades that cut in both directions and when it gets dull, I just take it out, flip it over (upside down) and have a new set of teeth at the cut line and the worn out teeth above. I double my mileage that way. ;D

Post by: cameronj on November 28, 2011, 12:23:35 pm: I cut mostly hardwoods and plywoods. So when the blade is dull for cutting hardwood, I put it in a separate tube (labelled "old skip 2" for example). Then when cutting stacked plywood, I will use the old blade because it is still sharp enough for ply for abit.

I have tried that too Roger, but I also found that when the blade did break which is most of the time, it broke where the old cutting area was and the blade tempered there. I hate to have blades break. I have a defibrillator next to my machine for when that happens.

Post by: GrayBeard on November 28, 2011, 04:24:23 pm: One GREAT thing about that 'foot switch'!

When the blade breaks your natural reaction is to jump away and that shuts down the saw!!!

Chuck, I keep some 'paper product' and a change of underwear close by for when blades break!!!

Post by: Danny on November 28, 2011, 07:04:34 pm: Roger.... I have NEVER used the Crown Tooth blades. Do they cut as smooth as the FD-UR's which leaves hardly NO fuzz on the bottom?
I really like your way of using them. Look forward to ur reply. Danny :+}

Post by: spiderman on November 28, 2011, 08:22:05 pm: when mine gets dull i toss them away and grab a new one it not worth using a dull blade you could slip and cut of a finger. a sharp blade is a safe blade got that everyone and steve good i hope you do too.
Title: Re: Blades cutting like cutting butter.... :+}
Post by: dgman on November 28, 2011, 10:08:45 pm: The only way you could cut off a finger on a scroll saw is if you purposely held your finger against the blade, and it would take quite a while to do it too!

Post by: dgman on November 30, 2011, 09:55:39 pm: So, do you have blades that are designed to cut bones?
