From an aesthetic point of view> Bear in mind that the proportions between pipe diameter and bending distance are very important to „please the eye“. If it is too wide it looks „unpleasant“ but if it is too narrow it does so as well. See for example Leo Rowsome´s proportions supplied by Christopher Bayley:

I’ve just started out un-officially, no-one is trying to shut me down. 
Honestly, I don’t see what all the fuss is about?
After all, it’s a business for some HOBBIES for others. It’s a hobby for me.

Don’t mind the fussers. You’ll have to appreciate their “Support your local pipemaker” stance from time to time. You just keep doing your thing and people like me who are interested will keep an eye on any updates, photos, etc.
Are you using someone’s plans for the drones?
I applaud any and everyone who tries their hand in making these things, or some aspect of them. This sort of thing keeps the instrument and its music thriving. Those who are currently well known makers of the Uilleann Pipes and their apprentices do not have anything to fear. In the case of Mr. Woof, Mr. Gallagher, Mr. Koehler & Mr. Quinn, Mr. Roggee, Mr. Fromment and every other highly sought after maker, there’s more than enough work to keep them busy… for decades in some cases.
Right now, from what I can gather, the demand is higher than the supply.
FOR SALE: Geoff Wooff full set in B
NOT! 
PD.
Well, I’ve had my heart stopped for today… 
Using the C ginsberg plans,and a bunch of help from different sources but came up with C sharp in the true pitch..but I’ve got a tenor buzzing to say the least.
I mentioned it as a joke some time back but when you consider the 14 year waiting lists for the likes of Wooff & Froment, a person could learn quite a bit about pipemaking in that time and make themselves a fairly respectable set of pipes, not to mention building their own reputation.
For those of you who embark on the journey, more power to your lathes!! I’ll look forward to enjoying the fruits of your labours!!
