Andreas Preuss Posted February 25 Report Share Posted February 25 Just a question out of curiosity. If not, where is the major problem doing this with a CNC machine? Quote Link to comment Share on other sites More sharing options...
Don Noon Posted February 25 Report Share Posted February 25 I know Molnar does, and I am working in that direction. For me, the major difficulties are: Making the model. It's a very complicated form. Fixturing and indexing to get all 4 sides to match up Tools to hollow out the pegbox and mill into the throat of the scroll. There are some long reaches with skinny tools, not the nicest thing. I'm currently partway thru all of the items, and have not cut a single chip as yet. Quote Link to comment Share on other sites More sharing options...
Advocatus Diaboli Posted February 25 Report Share Posted February 25 I’ve cut out a couple one the 4th axis just to see how hard it would be, but I enjoy carving scrolls too much to be willing to give that up! Quote Link to comment Share on other sites More sharing options...
Michael K. Posted February 25 Report Share Posted February 25 This CNC is not really Homade. But how many Scrolls you carve by your own Hand till all is set-up perfectly to compare? Quote Link to comment Share on other sites More sharing options...
Mark Norfleet Posted February 25 Report Share Posted February 25 Just like that Don! Some of the cutter choices were interesting, particularly the conical one. I’d love to have the scroll in my hands to look at. I heard a lot of what could be “chatter”, but perhaps the tools are sharp enough for there to not be much of an effect on the finished product.

Seriously, who has the money or room for something like that? Quote Link to comment Share on other sites More sharing options...
scordatura Posted February 25 Report Share Posted February 25 https://youtu.be/uWCimeKzh1k Personally, I like the fine work of scroll carving. The removal of large amounts of wood is a task that I am not that fond of. Quote Link to comment Share on other sites More sharing options...
Shunyata Posted February 25 Report Share Posted February 25 This is where the difference between artistic and pecuniary influences shows up. I am an ameteur with an overly romantic view of violin making. But even my shop has a bandsaw and a drill press. Quote Link to comment Share on other sites More sharing options...

Shelbow Posted February 26 Report Share Posted February 26 I used to do a bit of CNC work on a 3 axis Haas machine a couple of years ago. mainly prototype models. The CAD models were always super fine in detail from the designer's and we had an ancient version of MasterCAM. It wasn't enjoyable. We had to use these ultra fine 1.5mm milling cutters ( I'm not sure why they made metric cutters) from this US custom tool maker to cut a lot of the radii and there were loads of bloody Fibonacci curves. I hated it, I much prefer doing things by hand, but I respect the work needed to program something complex like a scroll. Quote Link to comment Share on other sites More sharing options...
MANFIO Posted February 26 Report Share Posted February 26 My Hillbilly CNC carved this viola scroll in just three days! It takes ages to program... mainly to "teach" the machine to use scrapers that work better than those rotatory tools. It makes a mess, but my workshop is already very messy.

catnip Posted February 26 Report Share Posted February 26 This guy uses the "lock and key" method to carve a scroll (around ~15 min mark). Quote Link to comment Share on other sites More sharing options...

Can you introduce some random errors in the cnc so it looks like it was carved by a human being? "The secret of success is sincerity. Once you can fake that you've got it made."

How long does it take you to carve a scroll by hand? Assuming a regular working day, do you save any time? Quote Link to comment Share on other sites More sharing options...
Bodacious Cowboy Posted February 26 Report Share Posted February 26 Making a scroll by CNC is about as appealing to me as a date with an inflatable doll. Quote Link to comment Share on other sites More sharing options...

Michael_Molnar Posted February 26 Report Share Posted February 26 I use a CNC to rough them out, leaving room for artistic finessing. It is fun cleaning up and adding the details. Drawing a scroll in 3D is not easy. Quote Link to comment Share on other sites More sharing options...
Andreas Preuss Posted February 27 Author Report Share Posted February 27 Reading comments here, I would suggest to use the CNC as a roughing out device and not to get the scroll completeley finished. If I would imagiine to work from precise sawcuts (made in this case by the CNC machine) which are on both sides exactly the same, the finish shouldn't take much more time than giving a CNC scroll the final touch.
