This is a workshop at the university where I am working at, part of the work is finished at this place.

Thanks Jens and Peter for your kind encouragement. This is a new recording using my cell phone that presents a small part of Mozart performed by a friend of mine.

Only the 4' pipes were used.

Hello organbuilders,

I really miss everyone very much and I am always appreciate for the generous help you gave me during the building process, this is the latest recording of this small instrument by my friend, I hope you could enjoy it and I am still trying to optimize the instrument.

Best regards to you all,

Xiaohu

Thank you Samuel and JGB, here is another short video myself playing some chords with 8 foot closed pipe. https://youtube.com/shorts/zlfdRxzXUO8?si=rzKb_89IaLoCxoII

Zitat von SamES

Does the large double-bent pipe have enough space above the labium? The upper part of the organ is placed on top of the box with the blower, and the bottom seems to be just above the labium of the pipe. Thus, the pipe should be massively too low and sound bad. Greetings! Samuel

Thanks Samuel for your kind suggestion, it is indeed a problem but I manage to solve it.

I upload a short video of the chest organ at its present stage, I hope i could somehow finished in October.

Thank you all for your kind surpport during the process, I really learnt a lot and enjoy it!

Hello dear organ friends, it is been a while to update my progress in organ building, cheers!

The "C-shaped" pipe is difficult to make and to make it sound nice, I will try it again using a different approach.

The leaking between the channels of windchest is indeed troublesome, i am still fixing this problem using glue bath.

I hope it can make sound in next month. Xiaohu

Dear Hausorgel friends，

Now is December, here are some updates of my project, thank you all for your kind support, hope it can be finished by next year!

Best regards, Xiaohu

Haven't been making updates for a while, here are some recent progress of the chest organ building, thank you all for your kind support during the process.

Best regards, Xiaohu

Ausgezeichnet！

Thank you Jens for your kind response, best regards, Xiaohu

One more question, what type of wood you use for the pipe?

Hi Jens, I understand how it works now, your approach is indeed very effective in making a slope, can make several front board simutanously, but a little drawback is without "two legs". Are there any difference in sound with or without the 'legs'? Thanks, Xiaohu

Hi Jens,

Is it possible to record a video to show how it works? I am also trying to figure out a way to work with the upper labia on the front board. Thanks, Xiaohu

Very impressive, huge project! looking forward to hear or to watch it plays.

Best regards, Xiaohu

Thanks Samuel, I am recently concentrate on the manual and start working on the bellow. Here are more photos of the manual, the sharp keys are made with the same wood and covered with a piece of cow bone. It is indeed looks better than excepted. Xiaohu

Hi Samuel, the sound of the laser cut pipe seems to be fine, I will find time to record and give the frequency spectrum if possible. the air block needs further modification, I will try a new disign later on.

Meanwhile，I would like to ask have you made any sound comparision with / without the glue coating on the pipe inside? I think surely the glue would make the inner surface very smooth, but it would spend a lot of glue as well!

Meanwhile, some update on the keyboard skin, it is indeed quite time comsuming on the manual.

Dear organ friends, some update on the organ pipes, I have made upto 20 pipes now, the small pipes on the right are the test pipes I made previously.

I also tried a new way of preparing the material for the pipes, is by laser cutting, I made one pipe and it sounds better than expected.

The upper labrium I made seperately by hand cutting and milling a small piece of plywood, to replace the glued triangles.

Looking forward to your comments, Best, Xiaohu

Thank you Samuel for the information. I am going to dedicate more efforts to make the keyboard as perfect as possible. I am planning to either use Teak wood with cow bone on top, or still using ebony with cow bone on top. boxwood is also not very expensive in China, probably I will try that also.

But right now, I think I am continue working on the wooden pipe and the windchest. Best regards, Xiaohu

Dear organ friends,

Some updates on the keyboard, I contacted a local workshop to carve the keys using the engraving machine, still there is more work to be done such as polishing and fine tuning, but already quite happy.

The white keys I use beach wood as key body. And the key covers I use "Purple Sandalwood" translated from Chinese, I think it is a type of ebony, the thickness is 2mm. Is it too thick for the key cover?

Meanwhile, I don't know what material to choose for the minor and sharp keys. Any suggestions?

Best, Xiaohu

Hello Samuel, this post is indeed very impressive and helpful! one question is about the labium edge thickness, I used to make it as sharp as possible but after having the opportunity to inspect some "real" wood pipe I found the labium edge is quite thick, what are the differences in sound considering the edge thickness ? it would be interesting to do various experiments to check the sound.

Another thing is the height of the labium edge to the air outlet slit, I think the lower the height would yield relatively large sound? and I guess that the lower the height would suppress the first order harmonic and increase the 2nd order harmonic. Best regards, Xiaohu
