The Piering contrabass depicted is, if I recall, in 12' F with attachment to 18' B flat.

Doesn't change the fact that the slide crooks are parallel rather than crossed.

Since the crooks on the old Conn were crossed and that was the model, I don't see why you couldn't use the same pattern.

Crossed crooks will allow the mouthpiece and connector to be closer to the bell.  Is this important?  I don't know.

IMHO,  crossed or parallel crooks won't matter unless you're REALLY into asthetics.  Then you can have it built to your liking at your expense.

Also,  I don't think the mouthpiece position in relation to the bell would change much with either config.

For the sake of comparison of different slide configurations, here's Robb Stewart's page on how he made Bill Reichenbach's contrabass:

Hi guys,

Here are some photo updates! Brad's been making some progress.

Quad slide alignment! You could almost play blue bells on it Amazed


Bell mockup:


The big bow is too wide, Brad rebent it to a more friendly shape:


Finished back bow, with ferrule on the bell:


More coming soon!

I've nothing to back it up, but crossed crooks always seemed more mechanically sound to me; viz. the point of maximum stiffness is out on the floppy-around end of the slide.

Brad really wanted to make a seamed copper tuning slide for it, to give a warmer more flexible response. We're planning on having it all silver-plated when finished.

The tuning slide was hand made by me from seamed copper. It's a slightly more gradual taper than a normal trombone tuning slide (remember this instrument is twice as long as a bass trombone), so it was necessary to make a custom crook. Since I was making one from scratch, I asked Noah if he wanted it to be copper and he said yes.

By the way, the reason I'm holding it weird in the picture is because it's not soldered together yet, so I was trying to keep it from falling apart while I verified the pitch is correct!

By tuning slide, do you mean the J-bend?  Because it looks like the tuning slide is in the handslide (a genius idea for more than one reason!!) and is cylindrical.  Or maybe I'm just confused.

No, the tuning slide is in the smaller of the 2 loops in the bell section. (The valve wrap has not been made yet; the smaller loop you see is not the valve wrap; it is part of the main BBb horn.) The crook at the top of the handslide does not move.

Appearances can be deceiving!  That sure looks like a moveable crook on the top of the slide.

Got a little bit of work done on the beast this week:

While Brad cleans parts, my daughter helps around the shop after school by providing a boost to morale.


The valves have had holes drilled for stop plate and witness marks added for alignment:




Brad lines everything up in preparation for hot work and assembly of the bell section BBb loop:
