Default Knowing when a hide bag is done

Our band purchased goat hide bags November of 2018 in preparation for the Glasgow Worlds last Summer (2019). As someone that always played an all Bannatyne(?) synthetic bag I had to learn much about tying in and particularly seasoning and re-seasoning, initially a real PIA!
I don't mind the bag and actually think it's gives the pipes a nicer more resonant sound.

Not looking to replace it or anything as all is well but how does one really know when the bag is just plain worn out and needs replacement?

Thanks

Jim

When it won’t hold air, even after seasoning.

Or the skin develops a thin spot or hole.

welcome to the world of hide bags my friend. Wait until a drone reed falls in.

Like cane it isn't the end of the world if you have a routine and can keep it at optimal condition. It's definitely a steep and frustrating learning curve until you do and even then it's usually not worth the trade offs.

This. And those thin spots are permanently 'wet' (seasoning seeping through).

I have a hard time believing a hide bag is worn out after ~15 months. What brand/model of bag is it?

I've had the same L&M bag on my pipes since new it 1986. There is no sign of it wearing out yet.

I think the fact that it is a goat skin may be the problem.
Ten to fifteen plus years for a cowhide, fiveish plus for a sheepskin but goat is really thin.
Not sure that any tonal "advantage" is worth the short life and work involved.

Like I mentioned there is no issue with the bag but I will keep an eye out for any seasoning that does not work, wet spots/ thin spots.

It's heartening to know some of you have had your bags for many years without issue.

My understanding was that goat had the advantages of sheepskin combined with significantly longer durability. I've had a goat on once but that lasted two years without issue, though that said I've kept sheepskin on for 2-3 years at a time as well.

"think it's gives the pipes a nicer more resonant sound" I've always thought the same thing. It's almost as if the inflated bag is like a drum giving off its own vibrations.

When seasoning starts seeping through (forming sticky patches on the outside of the bag), it's on its last legs. 2-3 seasons, tops, for these in the US.

Default Re: Knowing when a hide bag is done

The problem with hide bags (and probably any type of bag also) is that the deterioration is gradual. Which basically means that you don't notice that it's not as good as when you first tied it in. The hide bag I had prior to the Gannaway I have now went like that. It lasted 2 years and then I bought a Gannawy. The difference was quite remarkable - although when I first tied in the previous hide bag it was nice and air tight when brand new. With corks in the stocks and seasoning, I blew it up and it stayed that way for over 10 minutes.

I would replace them every couple of years whether you play a lot or very little. Can't keep up great tone and sound with a leaky bag!
cheers
Andrew
