Default restrictive drone valves

I purchased some of Mr. Hylands drone valves a few months ago to try out. I put them in my pipes for about 2 days and removed them as they made it incredibly hard to blow. As I was looking at them again this past weekend, I noticed that the opening inside seemed extremely small (about 1/8"). I figured what the heck I'm not using them the way they are anyway, so I carefully drilled out the hole in small increments to 1/4". Tried them again, had to re-adjust the tension, and 'viola'!! Like Buttah!!
They are functioning as originally expected; starts and stops are clean with more pressure available.
Just be careful not to drill too far in as the adjustment rod could become damaged.
If you have some and love to hate them, maybe this will work for you too!

Does this brand of drone valve stick up into the underside of the stocks? If so, how have you found them to change the drone sound? Most drone valves I've tried in the past really cut down on the drone volume and tone.

The Hylands Inline drone valves are designed to fit between the Ross box and the drone hoses and the strength of the valve is adjusted with an allen wrench. I use them and I don't think the drone volume and tone suffers.

A couple of us in Atlanta have taken out the Hylands and found a larger sound from our drones. That has be noted also by the pipe sergeant while tuning us.

There doesn't seem to be any logical reason why the hole in these valves is so small (approx. 3/16") relative to the Ross tube and a regular drone bore. I'm surprised people are able to play them without having significant problems getting enough air to their drones. Although, maybe Peter and I play bigger bagpipes than anyone else...

I bored mine out but they still offer too much restriction to be of much use to me.

Hey,

I play the Hylands valves, haven't and any problems with getting air to the reeds. I play Crozier cane and glass fibre. The valves do dull the drone sound slightly but nothing to worry about. maybe check you reed set up.

A good portion of my band plays the Hyland valves with no problem. I personally prefer the Ash plugs as far as ability to cut off air flow and the hole is about three times larger so it should be less restrictive. Even still, I haven't found the Hylands to be restrctive. I even took them out for about 2 weeks to make sure I hadn't forgotten how to strike-in and cut-off a bag with out valves and haven't noticed much of a difference.

The whole point is to restrict airflow so they're easier to blow. If you do that to the drones, but not the chanter then you can play a stronger chanter reed without having to open the drones up to compensate. When you balance the drone reeds they'll take the minimum of air.

Can you please expand further. I've never understood these valve things. Then again, I've never had any trouble with attacks and cutoffs. Something about balancing the sound? I've always just adjusted the drone reeds to suit my chanter, re: balance and tone.

I wonder ... are these things a way of acheiving good balance, and solid attacks/cutoffs, without having to learn the technique? If so, I personally don't care for the idea.

Cheers,
Scot

Two different issues
1. Restricted airflow (drying canisters have the same effect)
2. Valves
I was talking about airflow.
Balancing the drones is something that you do to check that all three take the same (minimum) amount of air. It also helps with strike in/cutoff. Get your teacher to show you.
