Jim your going to like this one so much, you'll want to sell all your used Seydel diatonics ! LOL. At first I thought those are valved reeds. I still think their valved reeds, but I didn't think chromatics were valved ?

And I Thank You !!

This is getting close to absolute perfection.
For you to get a clearer picture what I've done:
It was a custom-built chromatic deluxe with brass reeds, tuned to TrueChromatic LC
Seydel has NO steel reeds in those keys, so I thought it was impossible to build a steel chromatic in my tuning
However... ;)
I've noticed that the lower reeds are equal in width to 1847 reeds.
I've also noticed that Saxony Orchester has top reeds that can be retuned to pitches that I need.
So I took some reeds out of several 1847s and the Saxony orchester.
BUT...
1847 reeds are SHORTER than saxony reeds.
SO I had to drill the rivet holes longer to move the reeds forward to match the slot length.
This means each reed was drilled and fine-filed for at least 20min.
Each reed is carefully centered and screwed to the reedplate.
Huge amount of time and work...
The only brass reed left is 1 blow/draw, because it's too long.

Yes, those are valved reeds...
All normal chromatics are fully valved.

Jim is it possible to turn an F sharp diatonic harp into an F major through filing. I have been experimenting with gapping and filing but iam only a novice so any clear instructions on this would be good.Thankyou.

Looking good jim, you have extreme patience man.
@ sion13 im no expert but im sure you could tune down but probably not a good idea for a novice to try.
Ps .get a strobe tuner if you want do any accurate tuning

@sion13: sure, why not? Click on my picture for a forum where you can find instructions on how to tune instruments.
@jimbo-G: I've actually finished only half of it. I've run out or bolts, and have to wait until new parts arrive.

Here's my next project - a LOW LOW D using only one reedplate (not several parts of reedplates like I did with my LLD)
Notice the slot length...
I've also managed to file a C3 reed down to C#2!

The uneven place in the 3rd slot is where the old rivet hole was...

Thanks jim. That question was driving me nuts,I asked google and got some proper random results. I watched your vid and it seems pretty straightfoward. I got a Korg CA-10 for tuning it aint been out the box yet so it seems like a good little project to christian it with.Nice to get a response without someone telling me I need to buy this or that.cheers
