--- Quote from: RandyT on January 02, 2024, 11:57:39 am --- --- Quote ---1 mm is considered to be very wide, 1 cm would be like trying to use a jigsaw to do fine cuts. Doing a really tight radius would be impossible, nevermind trying to do a 90 degree angle. --- End quote --- Have you ever considered trying a diamond wire saw? .6mm kerf and it doesn't care which direction you go. The only drawback might be loading, but I have found the remains of a dried up tube of silicone caulk (waste not, want not :) ) works very well for cleaning wood out of sander belts, etc. so it should work for this as well. --- End quote --- Diamond wire is not required. I have used .6 mm wood blades without any problems before stumbling onto the .3 mm ones. .6mm is too wide. The point is that a .3 mm cut is so small that you almost can't see it. If you have a shape that has two colors, you can cut it in half, paint the halves and glue them back together without anyone noticing that they have been cut. Using a .6 mm blade, that cut will be visible. --- Quote from: Zebidee on January 02, 2024, 02:17:46 pm --- --- Quote from: yamatetsu on January 02, 2024, 04:20:42 am ---Doctor: Nurse! Scalpel! Nurse: How about a hacksaw? --- End quote --- Seriously though, a hacksaw would be a better choice than scalpel if you were performing an amputation. Dr Zeb would probably want both, for different parts of the job. --- Quote ---1 mm is considered to be very wide, 1 cm would be like trying to use a jigsaw to do fine cuts. Doing a really tight radius would be impossible, nevermind trying to do a 90 degree angle. --- End quote --- The suggestion was purely for those funky straight bits you mentioned, not the fine cuts. But I get that you might make another choice, maybe something in between, a bit less like a hacksaw and more like a fretsaw? --- End quote --- The in between choice would be a .6mm blade which works fine, but the cut is too wide. Alternating between the two blades woud be too much of a hassle, plus you would notice the transition from a .6mm cut to a cut half the width. The problem I most likely have is that you have to put the .3mm blade under extreme tension to keep it from flexing. The locking mechanism uses this to hold the blade: You just twirl the lever until the blade is trapped between this screw and a metal plate in the saw. If you don't do it tight enough, the blade slips out. If you do it just right, the blade is held and hopefully won't flex. Overdo it and you can kiss your saw goodbye. It's like overtightening a screw, that thing will never hold a blade again. The saw has two levers, so if you overdo both, the saw is useless. After finding that out, I had to buy a new one which cost me about 30 Euros. So I'm a little apprehensive when tightening that lever. |

If you had a little more space you could get yourself a scroll saw, which is essentially a powered fretsaw with a table. Gives you more control for those fiddly bits. |

I also thought that the separation lines were part and parcel of the style of this type of medium. It seems to me that a piece where multiple colors are desired would just be painted that way. I guess my naivety is showing when it comes to this art form. BTW, the kerf on a 50w laser is ~.13mm. Usually smaller with less power. Just ribbing you a bit with that info, I get the reasons for not using one. ;) |

It's not always my goal to make it clear that the picture consists of pieces. It's nice to have people go "Nice painting! ... Oy, that is not a painting!" The latest piece I made in this style was shown to 6 people, two of which actually touched it to confirm that it isn't a painting. Mission accomplished. --- Quote from: RandyT on January 02, 2024, 04:32:46 pm ---It seems to me that a piece where multiple colors are desired would just be painted that way. --- End quote --- To me, that would be the cheap way out. If I don't bother cutting those pieces up, I might as well don't bother cutting any pieces at all. I only do this when a multi colored piece is too small to be cut up. |

I accept at face value that your guy must make pretty special saws to impress you, but there must be hundreds of fret saw manufacturers out there. Or maybe all the others junk, explaining how PBJ found a set in a dumpster. |
