Going Out On A Limb - Bending Iron

Recommended Posts

I have developed a full arsenal for rib bending, The c-bouts can cook a minute while I put the small bend on the bouts then slip that around my diesel piston, which is sitting on a hot plate, the rib is held in place by a copper strap, I just slide it in there,It ends up perfect every single time without fail,, no fussing around what so ever, I mean never, ever ever. I don't like futzing around with  breaking highly flamed pieces of wood,, ever!,,, then I change out the c-bout, then bend the small bend in the bouts then change out my piston,,,, and on and on. It's all plugged into an old hot plate converted to be a variable power source to keep the temperature steady. The old iron can glow red if you forget it,,,CAREFUL! The c-bout bender is strad on one side and Del Gesu on the other. The wooden horn and iron are what I use to adjust for different things.

Luthier's Bench/David Stuttard: The one I use myself and like it very much. I bought mine many years ago, and I understand that communications/delivery times have caused issues more recently. There were a few people complaining about this on the Newark school facebook page recently, and maestronetters have also had some frustration. Great option if you're prepared to wait, though.

I purchased the Luthier's bench Iron. I echo John's comments with a little more local colour on the purchasing and shipping experience. When i bought mine a couple of years back they only had a 110v iron. They wouldn't ship it to Canada because they didn't have the UL? certification. So i had mine made as a 110v iron with a UK plug and had it shipped to a friend in France who then shipped it to me. So net net, it was a huge pain in the you know what. In the end it was worth it -- it is the best iron I've used and it is big enough to do a cello. Their bending straps are also first rate - flexible enough to bend around the contour of the iron without kinking. just sand off the edges as they are quite sharp

Diesel piston!!! Now why didn't I think of that?

In reply to FinnFinn the electric frypan in the pic puts out enough heat. It is just a matter of sliding the rib under the strap as far as it will go and slowly rolling it across the pan.

The C-bout forms need to be made to the right size as far as distance between corners is concerned and that its shape allows the rib to be over bent slightly at each end. Also the straps need to be no thicker than about .3 mm so that they can be bent around each corner staying in contact with the rib.

You need a spacer under the strap where it is screwed to the form at one end and the alum. bracket at the other end acts as one. If the spacer is the same thickness as the rib material it is effectively clamped in place so that it doesn't slip when bending. I spray a little water under the strap when I'm ready to start bending. When it starts hissing I know that is hot enough.

The upper and lower bout forms are much simpler to make and use. I didn't show it in the pics but I pre bend the ribs here with a length of wood with the leading bottom edge radiused and a strap attached, although It can be done without a strap.

You can use a chainsaw or a weed-whacker piston for the tighter bends. ;)

For those really tight curves, one can use the piston from an .049 model airplane engine. Just sayin'

Thanks to all for the responses. I'm leaning towards Luthier's Bench aluminum.......................and a strap.

The Luthier’s Bench straps work well.  They are thinner than most straps which I think works well.  I have used the Luthier’s Bench straps with my Gewa iron (for cello) and my custom violin/viola iron made by someone in school that was based on the Gewa with a slightly tighter curve.  It’s a good combination but if I were buying now, I would probably get the Luthier’s Bench one.  It’s hard in general to find something that does everything well.  

 

A side note:  I believe Aehnelt used to make irons for Gewa.  Not sure where I heard that info but it makes sense.  

Here’s a photo of the custom one just for my vanity sense.

Since there was some talk about poor communication and long shipping times from Luthier's Bench, I thought I'd give an update.

David (Luthiers Bench) responded very promptly to my email inquiries. I ordered the iron from his website, and it arrived yesterday. Wow. So that is delivery in 8 days, from the U.K. to U.S.A. Better than some domestic suppliers. I haven't used the iron yet, but I am very pleased and impressed by the service. So there you go.
