I have finished rebuilding the bellows of the antique roller organ I purchased last fall. The bellows has sat on the dining room table for the better part of this summer and I've got to say, it feels really nice to have the table back!
Here is what they looked like when I got the organ:

They didn't have too much power, partly due to having improper coverings for the exhauster valves. The inside flaps were index cards and the exterior were paperback book covers. It struggled. The flaps have been replaced with leather.
Here they are now:

I'm happy to say that the organ now has a robust sound and projects well. Video clip below.
I worked on this project pretty slowly. It sat many days without being touched, partly because I have had so many other things going on, and partly because I was stalling... afraid of botching the job. Well it turned out OK.
It's my first experience using hot hide glue and my first bellows rebuild ever. I was apprehensive about all the unkowns. Working with hide glue turned out to be a good experience and I'm really fond of the stuff. There is a drawback, though, and that is the time it takes to prepare it for use. The granules have to be soaked in a proportion of water at least 40 minutes before heating to 143F which can take an additional twenty to thirty minutes. Since the order of assembly is important, there were times when I was only able to glue one or two small pieces and it all had to dry properly before proceeding (I always gave it overnight to dry.). The good news is that unused glue can be capped and placed in the refrigerator for keeping. It's a great glue. Strong, but easily removed with heat and/or water. It's basically the same thing that Jello is made from! Non-toxic is a great plus.
I am chuffed with the results. Next time should go even better--and that will be the pump organ bellows. I have confidence now that I can tackle the job with gusto. I'm practically raring to go!
There is still a small issue with the roller organ and that is one of the safety valves is not setting tightly closed because the exhauster board that it is attached to is slightly warped. I exchanged the badly worn leather for that valve with thicker leather hoping it would make up for the almost imperceptible warp and it seems to work. But the original spring for the valve is not strong enough to keep it shut due to the extra weight off the new leather. I ordered a new spring today and I'm hoping that will fix the problem.
Here is a short clip showing off the new bellows (best viewed on YouTube):
In other news, here's a short clip of my most recent acquisition of entertainment from the late 1800s. I love this one!
In yet other news, I demonstrated a bit of wool spinning at our town's annual 'old home day' on Saturday. It was an enjoyable time and I have to say, for being such a small town, the fireworks display is pretty darned good. Being up close is a special bonus.
