Okay ... another question on fine cuts
What if the cut you're making requires precision points? The following
cutout shapes (link below) could be done on a scrollsaw, but it would be difficult to get the lines perfectly straight. http://www.deltamesa.com/Wood/tess.gif Maybe a jig of some sort with the scroll saw? These are tesselation forms and so I'd have to be able to cut out several of them with a fair degree of accuracy. Other than simply having a surgeon's steady hand, what's the best approach to cutting these shapes? Jack |

If I had to do it- and I think I'd avoid it- I'd cut them a little oversized on the bandsaw, then file or sand them down to the mark. Looks like an awfully fussy project, though. |

Not if you are any good with a scroll saw. My landlord has a guy who makes temporary tooling use a scroll saw free hand. For him, it would be a piece of cake. Lew |

Hello,
I commented Your recent posting on accurate cuts on small pieces. Tessellation forming means You readily have well determined geometrical quantities for angles and distances. Also, If I understand correctly, You want to make these cuts in a board. Because in woodworking there is no seamless zero-loss cutting, you need to correct the cut by blade thickness correction. If for some reason You have doubts on Your ability to cut by the hand guiding, then You need a jig. Actually, to me it's more fun to practice to do such things by hand, but sometimes something demands more for some reason. Just a suggestion: Extend the table of the scroll saw with large piece of fiberboard. If You already are aware of tessellation angles and distances, You should be able to define the placement of jig fence with a pair of compasses and a ruler. Note that You also must consider the dimensions and squareness of the workpiece. The challenge is that You will need one parallel edge in the working piece board for each cut angle inside the board. I count 4 cut angles. I do not know Your situation, but seems to me that If You cut these forms inside a chess board, You need extra assisting framing around the board where all of these angle are presented. Then You need either quite a lot of accurately cut straigth blanks to use with the static jig fence to compensate distances inside the board, or You need adjustable and very accurately positioned fence. It's going to be quite a hassle, but why not :) It's cool, anyway. If You need a lot of these, it is always possible to take them to Your nearest waterjet cutting service. They need a 2D cad file for the cut. I mean, if accuracy is the only thing needed here, then I in Your position would go for that.

I'd make oversized templates, clamp em onto my Gorton Pantograph Mill, and pound out as many a dem puppies I need, then clean out the inside corners with a chisel. -- Timothy Juvenal www.rude-tone.com/work.htm |

Seems to me that what you're doing would be a lot easier using marquetry techniques and veneer. Jack -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net) |

You might want to contact this guy:
http://pwdbp.com/? I meet him a couple of months ago. He built a very special sliding table for this table saw, yes table saw to achieve the cuts he wanted. Perhaps there are others who do puzzles that can help. There are links to others. Good luck! MJ Wallace |
