Oh forgot to mention!

I like to leave the leadpipe a little longer if i can than the normal standard bach C model as i think it improves intonation by having the longer amount of taper in tact.
You can achieve this by slightly reducing the bell length to compensate for the added length of the leadpipe
We are only talking an extra 15mm or so overall! if you can achieve this by leaving the full 15mm on the leadpipe then thats great, but sometimes this has a habit of positioning the leadpipe too far back at the reciever end.
So maybe you could split it and use an extra 7.5 mm onto the leadpipe itself and another 7.5mm at the bottom of the tuning slide.
This will add up to your extra 15mm in total and then you can cut the bell a little shorter.
But as ive mentioned in the previous post, try out before you cut the bell and only take mm's at a time to get the horn back in tune.

I think you will find the intonation is superior this way!

Try it as an experiment on an old horn you have lying around first.

I hope this helps a little?

If i have confused you in the way i have described anything then feel free to email me for further explanation.

Best Wishes and good luck
