Bending a rib
Thanks for the advice, Scott. Looking forward to seeing the progress on your wife's lute and also the lavta.
I finally tried out my bending apparatus today. As the doc pointed out, steel doesn't have good heat transfer characteristics; It takes a while to
heat up with the bulb, but eventually it does get hot enough to boil off water. You can tell it's sluggish, and when the wood takes away its heat it
needs a moment to respond. Tomorrow I think I'll look around the shop at school and see if there's any copper pipe scraps that I might be able to
substitute.
I did end up using the water spritzer before bending.. maybe after I get a few ribs bent without cracking them I'll move on to dry bending as you
kindly suggested, Dincer Bey.
At any rate, I was able to get the first rib bent pretty well to form, and I used the MDF/glass surface to joint it.
This rib is just for practice, since I cracked some of the grain while bending. After bending, I also realized that my neck and tail blocks could use
a little more shaping to match the form, so I'll need to adjust those before proceeding further.
Well that's all I have for today.. Jameel great job updating your site; the restoration looks incredible!
Jay

I suggest looking for aluminum pipe and a large diameter which will transfer heat faster, and to a larger area of the rib surface. This will reduce
the tendency to brack ribs. Its a matter of experience to judge how much pressure to apply and when to back off. Make plenty of extra ribs as they
will break now and then. (I still do).

Hey Samir,
Thanks for your nice comments. I think you'll find that Dr. Oud's book is very interesting, even if you don't plan on building. There's a ton of
knowledge in there, including tips on maintaining and caring for your oud too.
I'm glad you all are following my project.. I'll definitely post sound clips as soon as it's done, but at the rate I'm going it may be a while (and oh yeah did I mention that I don't know how to play the oud- I'll need help from
you guys when this is done  )
cheers,
Jay

Hi Jay, like you I'm working on my first oud following Richard's book, but I thought I might suggest 3" copper pipe which you can scrounge from a good
plumber. cut one end into strips 1" wide fold these across to close the end (but not airtight. Heat can be safely provided by a heat gun which are
available here in Australia for $20.00. This gives no ectrical risk or burn risk as would a gas torch. This has worked well for me on two guitars.

So what powers your heat gun? Solar? Nucleur? It seems that any heat has a burn risk of some sort associated with it. If it can scorch wood it can
surely scorch skin, no?

I'm sorry not to have explained myself fully. The heat gun is an electrically powered device used generally for things such as paint stripping. If it
is positioned in a way that places the nozzle in the copper tube the only hot surface is the tube. it is of course posible to burn oneself if the tube
is touched. This heating is managed without any flame which is a far greater risk I believe. I know that many members of the Australian Association of
Musical Instrument Makers Association have turned to this style of bender if they can't afford a professional device. Another thing I have found
useful for small items such as purfling is a household steam generator of the type sold for cleaning bathrooms etc. this provides heat and moisture in
one hit.

Does it blow hot air like a hair blowdryer or just heats up?

It blows hot air but much hotter than a hairdryer. I made the mistake with my first one of completely closing the end of the tube, the air had nowhere
to go and came back onto the hater and melted the plastic parts.

I use a small cappuccino machine and bent the steam pipe out, put a small heater hose on it and use it for steaming glue joints apart myself. So you
use it to soften purfling for bending? hmmm, I'll have to try that. I'm always breaking rosewood edsge bands, they get so brittle when dried out by
dry heat. The cappuccino machine is also handy for quickly heating up a cup of water for my hide glue/fondue pot or tea. I was pulling your leg about
the heat gun - I use one myself all the time to remove synthetic glues, even epoxys, carefully, of course.

Thanks for all the advice guys... I've been side-tracked for a while but hopefully I'll have some more pics real soon. The "Oud Projects Forum" is
really taking off! I'm learning alot from all of your posts. Glad to watch the Doc's restoration here, and Jameel's final product is outstanding!
It turns out my bending iron works just fine with a little practice, so I'm sticking with it for now... maybe I'll soup it up on my next build. I am
now able to bend the ribs dry and without cracking them.
After several attempts at glueing up the first ribs I've yet to be successful... I think I twisted the first rib a little on glue-up so it was hard to
fit the second without gaps in the joint. So now I'm starting all over with the first rib and we'll see if I can be more careful this time .
Cheers,
Jay
