more pressure when playing drones

I resonantly got a new chanter stock from Andreas Rogge for my D fullset which I tied it in myself. Chanter stock is airtight on bag

For some reason now I have more pressure when playing drones with chanter now which I didn’t have with my other
chanter bag stock.

I seem to be pumping more with bellows as could me loosing air from somewhere.

if the stock is tied in airtight, the only other variable is the hole in the stock where you plug the chanter in. If this is a larger diameter or different shape, you may be getting leaks from there. Some stock holes are tapered, others straight bore. I personally prefer tapered as I found you don’t have to be as precise with the wrapping on the chanter.
Also double check your reeds are snug in their seats. Last time I tied in a new bag (which was quite recently), I had a drone reed come loose inside the stock.

A slight taper widening towards the end of the stock is best as it allows for wood shrinkage and have come across this on several historical sets. Wood shrinks when it looses moisture and this is fastest at the exposed end grain causing a parallel bored socket to become a slight taper narrowing towards the end of the main and other stocks which can make wrapping difficult to get a secure fit or more likely to leak.

We are now into a soggy autumn so have the reeds opened up or stiffened, are the reeds seated properly, are the pipes secure in their sockets, have you tried plugging the stocks to check none of the tie ins or bag itself is leaking, are bellows tight and valves sealing properly ?

My Rogge full set was playing great when I was playing chanter with drones with old chanter stock on bag (one I have for sale)

My Lawrence Thomson bellows is airtight and working fine with the Ray Sloan bag.

It must be to do with the new chanter stock on bag now that I tied in.

I can’t find any leaks from any other stocks on bag.

Will send bag to Ray Sloan and get chanter stock tied in and also get checked other stocks on bag for leaks or re tie again.
