Hi CJ,
The stuff you make, particularly the bellows, look great and from what I hear, the quality is also very high.
I’m very much in favour of building sets (mainly cause I could never bring myself to pay $5000 + in one go for a full set, even if I had the money). The ability to start with the practice set and build it up is one of the great advantages of uilleann pipes. More power to you for helping us less well-off pipers pursue our passion.
I have, however, one criticism: when you advertise the components you make, you don’t give the measurements of the connectors, which makes me a little nervous about bidding. Any chance you could do so in the future?
Thanks, and keep up the good work.

This bellows delivers 1.4 liters of air per stroke, determined by testing.
In my experience, the volume of air delivered has nothing to do with efficiency or efficacy of a particular set of bellows. That 1.4 liters of air may seem like next to nothing under standard playing pressure exerted on an Uilleann pipe bag. One must know the suppability of the gussets, the efficiency of the intake valve under system pressure, etc. Also, one must know if the bellows delivers most or only a fraction of its air. For example… What is the stroke volume? If it is really 1.4 liters then what is the residual volume?
One cannot judge a bellows by its appearance and a note on delivery of air per stroke.
I own and use one of these bellows. They are well made and solid, in addition to being very airtight. They are also very comfortable to operate. A good deal IMHO.
Hi PJ,
I appreciate your compliments, a sincere thank you. I also appreciate very much voicing your concern. I certainly will never better myself or my product if feedback, whether it be positive or constructive, is not voiced. I appologize for the oversight and I will be sure to post this information in the future. I would also like to add that I always welcome any and all questions about items that I sell, whether it be on ebay or not and that I will ensure a quick reply.
Hi Glands,
I agree that the volume of air delivered, in this case 1.4 liters, is not the sole factor in determining bellows efficiency. It is merely the output. Efficiency is the ratio determined by the total system input versus the output itself, which takes into account the sum of the characteristics that will impede the output. It is dependent on both the user as well as the design of the product… some of the characteristics you mentioned and others such as an open system (leaks), type of hinge and the associated amount of lateral movement, etc. It was not my intention to list all the design qualities necessary for this calculation or conclusion, but rather, to inform potential buyers that the output is 1.4 liters per stroke under normal instrument operating system pressure with a minimum amount of wasted or impeding effort. Any additional information that an interested party would like and that is not present within the add, I would hope would ask. I appreciate your feedback as well.
Cheers Joseph.
All the best,
CJ
Thanks for clearing it up. I was, of course, commenting on bellows in general. The more sets I play the more I have an opportunity to actually study the “powerhouse.”
