so you just bend it without heat or anything? How does it not break?

[@TwoCherriesIns]

I use heat, this is a link the the full series

Hi ! Very good job ! I would like to ask you what kind of aluminum foil and what kind of power supply do you use to heat the aluminum foil for bending violin ribs?

[@TwoCherriesIns]

The aluminum fol holds the steam against the wood; the heat is applied with a "silicone heating blanket" powered directly from mains 110V AC power.

[@allenwallace9747]

So how long did you have the silicon blanket running?

[@TwoCherriesIns]

Not very long, about 5 minutes

[@kennith.]

Quick question, can't you use the CNC machine to cut the ribs out in the exact shape without the need to bend?

[@TwoCherriesIns]

probably, but I prefer to bend them.

[@harrynking777]

Can you not use the middle parts of each long rib set as the c-bouts (each being inverted)? In that way you would not need the separate c-bout jig.

[@TwoCherriesIns]

not really, for one they are not long enough. It does allow me to bend the upper and lower bout sets for both sides at the same time.

[@guybooth20]

Cool! A rather different way of bending violin ribs. Where do you get the electric blanket from?

[@TwoCherriesIns]

I get them on eBay, mine is wired directly to mains but there are in line temperature controllers available.

[@TwoCherriesIns]

I've been bending guitar and mandolin sides this way for a while now. Extremely high success rate even with figured wood.

[@mkdijkstra4855]

and now try it with deeply flamed maple

[@TwoCherriesIns]

This is flame maple, And I bend it for a lot of instruments, It's much more reliable than hand bending, and more consistent as well.
