Thanks to the encouragement of some folks on here last time I posted, I've actually being making good progress with tuning and not messed any harps up for a while. Despite this I'm experiencing a repeat problem especially with lower reeds that the pitch will waver around a range of 4-8 cents after tuning so when I play an octave the lower note will be jumping about. I suspect that I may be bending reeds out uf shape when i'm tuning so need to re-shape??
any advice appreciated.
thanks Ed

Not sure Ed. do you know what it was like before you tuned it?
I've had reeds that won't give a stable tone, but either related to a leaky comb, embouchure issues, twisting reeds...maybe something else...

What do you mean by jumping about? Is it the needle on the tuner?
Tune the lower octave in relation to the middle octave - by ear. Only use the tuner to get close to the pitch, then fine-tune the pitch using your ears. Use a range of breath force to determine if you need to raise or lower the note. The tuner will be of no use to make those changes.

I hope that helps

I test harps w/ hard breath force all the time to see how fast the choke on the blow. I do this especially for harps that OB or players that play too hard. You can set reeds to respond w/ soft and very hard breath. It's a feel thing when adjusting.
PS wavering is very normal.
