Steam Box Idea... What's wrong with this idea?

Speaking of Trevor Gore... I've started using falcate bracing on my ukuleles and in making the braces, 3 strips of .0625" spruce are bent and then put in a bent lamination glue up rig using epoxy. Bending spruce is no fun on a hot pipe. It's slow, fussy, the fibers want to delaminate. I have been thinking about building a small dedicated steam box. Pulling all 3 of the strips out at once and bending them over a form with a metal back…

I tried it once for trying to bend mandolin sides. This was in 2006, back when the internet wasn't nearly as useful as it is today, so the attempt was pretty incomplete I think. If I remember correctl…

Side bending - actual problem or isolated freak out?

Hello All! My first post and I'm very happy to be here and share the highs and lows of this pony ride. After years of bending sides on a hot pipe or bending machines belonging to 'other people', I finally built myself a bending machine. Functionally it is great, but the result on some test material was far from great. See pictures attached. What you see here is a doug fir 'test side' that certainly came out guitar shaped, but oh my, what…

Cutaway vs. Scoop cutaway

Thinking of trying a scoop cutaway on my current acoustic build. I actually planned to do it but I’m having second thoughts. I have no issues bending a cutaway. Question for those who have done it - is the higher end of the fretboard still comfortably accessible with the scoop and, is there any perceptive difference in sound by saving that small portion of the upper sound box? I guess I’m just wondering if the extra work is worth anyth…

I had the same line of thinking. I appreciate your feedback. I haven’t searched the AGF for this topic yet, great idea.

Brazilian Rosewood sides thickness

I'm building my first BRW guitar, started with the back, pictured below. What do you normally thickness BRW sides to? I guess they can probably be a bit under 2 mm, but I don't want to overdo it in case there is some slight deformation that needs to be sanded later. I bend manually on a heating iron if that makes any difference.

Hi: I treat side thickness on Braz like any other wood and have not found that it needs any special treatment (other than your bank account). Of course, if the sides are figured or has flatsawn area…

more side bending

hello looths - i'm building my first guitar. generally following (and enjoying) the gore/gilet books. after 3 tries, i've yet to get a crack free bend around the nose of a venetian cutaway with a mahogany side. i made a version of the fox bender - using clamps on hand for the waist and cutaway, and a pid temp controller (verified accuracy), and am using a stew mac blanket and three straps. the recipe for my last attempt was: sapelle (fo…

Bending Crelicam Ebony

A client has asked me to build an acoustic guitar using crelicam ebony for the back and sides that he is getting form Stewmac. I have heard it's challenging to bend, and this will be an OM so the waist is pretty tight. Any thoughts or suggestions for bending these sides? I use a homemade bending machine modelled after LMI's latest design (may they rest in peace) and I have had good success bending rosewood, walnut, mahogany, and pau fer…

Side thickness recommendation

I am having a little trouble bending my first acoustic sides. The wood is a interlocked mahogany. I am hand bending on a temp controlled 2" curling iron. I have thicknessed the sides down to 1.9mm but still got some wrinkling and cracking trying to bend around the cutaway. I am trying to figure out how to improve this for the next attempt. I have read some conflicting information on how to do this though. Thus far my plan for the next a…

Hi Nicholas, I would agree with Anthony, it sounds like you need a larger surface area to heat up the wood. A small pipe only allows you to heat up a small area at one time. I have the ibex bending iro…
