What is an efficient way of bend Uke sides so they are uniform?
At the mo I use a violin rib bending iron.
It works but i am after something like a steam chest?...
Or heated bendind jig?
Any ideas please?
Pete

With a bit of practice and patience you should be able to get sides fairly uniform on a bending iron but if slaving over a hot iron is not your game then the other option is sandwiching the wood with a silicon heating blanket and heating up the blanket while pulling the sandwich tight around an appropriate wooden form. I used a blanket for a bit but I ended up going back to hand bending my sides in a bending iron.

Thanks Martin.
Perhaps I need more practice and patience then.
I have read about the "Fox" bender and other similar wooden constructions here on the forum.
I have to bow in shame and ignorance as I have no clue how to make a blanket or even heat it up.
I have read that some are heated to 100C.
Thats boiling point so pretty hot wot?
How is this heat applied?
How do I make the blanket?
Will the wooden structure not warp with the heat?
If I make one it will be quite small as it will be for UKE sides.
I can see how they are constructed and how they work but ignorant as to how the heat is applied.

Pretty much most pro uke builders I know will use both the iron and a silicon heat blanket. The shape of my ukes have a couple very tight bends that are very prone to fracturing if just done with a Fox style bender.

I hand bend all my sides to close to shape and set the bend on a solid form with the heat blanket.

My Ukes also have tight bends.
Figured Queensland maple doesnt want to know.
The shape is Martin Soprano 0 series.
I can still use the iron but can you please advise me how a heat blanket works?
How is it heated?

I have blankets from Michaels Enterprises and a couple of small ones from Keveno that you can get on eBay. You purchase them by size and wattage. I built a custom controler to control the heat. Much like the one you can get from LMI.

You absolutely never leave a heat blank unattended as they can get very hot very quickly with fire the likely outcome.

Crikey Allen.
With me, Murphy's law will apply.
If it can go wrong it will mate!
I can see me ordering the wrong size and Wattage.
I can forcast the controller going wrong or blowing up!
I think I will stick with the old Heated iron.
I had visions of steam chests but when I stand back and take a look.....
I am not into production here on a big scale.
Yes...I want to make Ukuleles but for me it will be a past time.
I just need to make enough to buy nice tools and carry on the love!
