Ok, so the universal may not be a historical organ, but is based on the barrel organ's humble beginnings.
I'm excited about my Christmas gift of the plans (wife) and have ideas I want to implement.
I have a few questions for the members here.
Has anyone ever put soft struck chimes in/on an organ? (not bells, but actually tubular chimes)
I have a lot of ideas to figure out, but for now I'm working on materials for the organ.

Well, since receiving my plans, I haven't had a huge amount of time to get much done. Business has picked up lately (figures, just when I want to play......)
Any who, since I didn't have time to do anything major, I decided to build a pipe. I sort of followed Phil's way with a MDF pipe. I cuts some pieces of 1/4 inch MDF, and made a pipe similar to the D# from the Universal plans.
This was a great test, because it has me thinking of some questions.
I would like a few different opinions or techniques.
In what order do you assembled pipes?
I started with the back (which in the end was not wide enough.....yes I know Phil, cut the back piece wide).
The sides worked well, but the front didn't end up flush all the way. Now I'm starting to question, how to put the front on. I'm going to go back and look at Phil's video, and see if he says.
the mouth was a chinch, and the upper lip (I just table sawed the angle in, and sanded).
The pipe does work, the upper doesn't totally touch the front center, but still the pipe makes a nice sound. It takes a lot of air (breathing used for now).
Give opinions or observations,

After careful review of Phil's video, he doesn't focus on the front of the pipe.
Has anyone built a pipe, from front to rear? I am concerned about the upper lip touching the front.
Maybe I should just buy a orbital sander.

Hi James, can you explain what you mean by the upper lip touching the front.
If you like I will do a new video on this but if you have JS plans you will see that’s how the pipe’s in my videos or put together.

The center piece of the front (short piece with the angle, which is actually part of the pipe) is about 0.010 inch from being flush. This lets the upper lip have a small gap behind it (if viewed with the pipe in an upright position)
I tried to make sure the front piece was flush when putting it in, but MDF is somewhat flexible.
I talked to Bob Meyer, and he assembles the pipes on their side. I may try that method next.

While browsing at some pictures, I found a major flaw that I created when I built my test pipe.
For some reason, I cut my pipe back full width. This resulted in my assembly from the back forward. I now see, that the front and back should be the same width, which would make the pipe built from the side.
I have no idea why I cut the back piece different than the front, but does explain where I went wrong.
Oh well, the reason I was testing. I feel confident now, that I can make a pipe that speaks, even if it is built wrong. :-)
I'm continuing with the bellows in the mean time, being more careful of the prints while building.

Well, attempt two worked better.
Last night I built a second MDF test pipe. I cut the front and back the same width, and even put a German mouth in this pipe.
There were a few things that I did differently. The pipe is smaller, the gasket is thinner (my calipers have died so I am guessing at gasket thickness right now). I used a 15 degree slanted mouth. I also cut the side bevels in the cut up area. The upper lip is not so sharp on this pipe (about a 1/32 rounded edge, maybe a tad bigger).
The pipe speaks well. This pipe is approximately an octave higher than the last.
I still need to make a jig to hold the front and back at a 90 degree angle relative to the sides. I used Bob Meyer's trick of super glue. I tacked the parts together with super glue, then went back with wood glue to finish the job.
Now that I know, that I can make nice speaking pipes, I will continue with the bellows, and reservoir. Pipe material will need to be ordered. I'm also going to "table out" my small Micro-mark mini table saw. It works wonders. I was worried the small saw wouldn't perform well enough to use in this project, but so far is performing flawlessly.
