That's a pretty cool storage rack, Ken.

Timbuck thats quite an impressive bender.
The rack is great too.

I am working on my first uke build and had a few issues bending the sides.

If I may ask, how long do you keep the sides in the machine? do you do multiple heat and cool cycles?
and finally how long do you keep the sides in the rack?
Thanks

What do you use for the heat source in the bender. I wasn't going to make a bender but my kids all want a uke. So maybe I could justify making one . Looks like a pretty slick set up.

Nice to hear Ken that you are not having more outdoor bonfires fueled by ukulele sides. Your picture below still haunts me...

I use a 500 watt halogen flood light with the glass front removed...You can get more details from this thread here http://forum.ukuleleunderground.com/showthread.php?31458-Bender-Getting-worn-out&highlight=bender+refurb

On the temperature gauge/meat thermometer I have a green and red mark (as result of trial and error testing), I start the bending on the green and switch off the bender when it gets to red...I then wait till it cools down to the green mark again about 4-5 min's....then remove the sides and put the next set in. I always wet the sides before bending....I keep the sides in the rack until needed , but I always adjust them a little bit more on the hand bender prior to fitting to the end blocks...I made this video last year https://www.youtube.com/watch?v=g5aYjINZ6kE

Nice Ken, initially I thought the bicycle pump was used in your uke building, but then I remembered you filmed some of your cycling excursions....

Ken thanks for the info and video link.
My bender suffered quite a bit of scorching this weekend so im likely going to make a new one for my next build, the inspiration is helpful.

Nice drying rack. Must be nice to build in batches.

Is your bender your own design or did you start from a plan. If so which one

I originally stole the design from Kamaka in an old factory video on YouTube and just built something like what I saw. https://www.youtube.com/watch?v=59wlZPczLZo I then added a few ideas of my own like the brackets to hold up the stainless top sheet and the halogen heat source.

On later videos I notice that they have now upgraded their bending machines to the piston type ones like the big guitar factories use.

How did you get the aluminum to hold the curve of the form so nicely? Mine is tacked down with nails and a little cobbled together

Hi Ken. Just wondering what part the Baxters Lentil & Bean soup plays in the process? I've got some in the cupboard :)

Well, I did have! I just looked with a view to lunch, and it's gone. Do you think Baxters Vegetarian Garden Pea & Mint might work as well for bending?

It's Stainless steel sheet ! And the ends are just folded under the ends of the mold.

The soup is just part of my secret formula to avoid cracking and creasing...And due to the fact that I'm in the process of patenting this wonderful stuff I cannot reveal any more ;)

My good friend Robin bought a Martin soprano from 1956 last week. It was in great nick, but there were several crease marks at both sides of the waist. So let's stop fretting overly about it already.

But I have never doubted you Ken - your ukes and your building methods are clearly a step up from Martins. When I played Prof Chris' one last summer it gave me serious builder's envy!
