A bunch of discussion concerning IP has been moved to a new thread. A friendly reminder: let's keep this one on topic, please!

Here's a link to a video by Ron Bentz of Jim Bach diving my Dacor Oly conversion, the Dacor 2020, at Fortune Pond. Not shown in the video, but he took it down to 112 fow. www.youtube.com/watch?v=o95pp000jYo

Fred, that's gunna look really great with those cans! Would you like me to design a custom-label for you?
JB
PS You can repair those plastic cans by using a soldering iron to weld the crack shut, a sort of cross'hatch pattern then filling the spaces with epoxy, then of course, paint!

Hello JB Of course , I like labels that you made already for Phil.😃 And I have front box without label. I just need to mesure de diameter , and send to you. BTW I glued the plastic with a sort of LOCTITE, it, is like a soldering, when I do that I open the crack to filled between the two side and then push to two side together. , but at the end I prefer take time to made the transformation with the royal mistral box. The plastic box a sill preserved religiously case of.., Happy new year again Cheer's Fred

Fred, when you get the measurements, PM me your e-mail address, and any thoughts of what you'd like to go on the label Bonne année! JB

Fred, My printing guy can print the labels in silver foil, or whatever you want when JB's graphic is done! He printed the HW Deluxe and Trieste labels.

Will this be in French, or English? Please remember, I can't spell for a damn, so make sure your nomenclature is correct!

Hi, Fred, I got your e-mail I'll be putting that label together for you soon. Do you want it to say, "Use compressed air only" etc., and do you want that in French or English: if French, can you send me your verbiage? Yes, I could have e-mailed you back, but I'm just trying to blow some bubbles here on the forum JB

I just picked up 2 Dacor Oly first stages for $10 each. One has an HP port adapter that fits in the reserve port. Score!
I am going to convert them both to DH, but have to decide how I will make the second stage bore. I'm still working on the center bore, rather than offset, but haven't yet decided how to get the jet right up into the intake horn.
I have a few ideas, and I think it's going to be the simplest method. More on that later!

I'm curious wha the shells in the video by Ron and Jim are? (It's the zoology major in me coming out.)

I keep going back and forth on the centered vs offset second stage bore. I think the biggest issue with the offset bore could be that the IP adjuster interferes with the potential lever movement. This may or may not affect the amount of air that can be delivered at depth.
I know that the second stage poppet does not have to lift very high from the hard seat in order to supply plenty of air. Even with the IP adjuster interference, the poppet probably can be lifted higher than necessary or at least, enough.
If that is the case, the offset bore has the advantage of bringing the primary jet very close to the intake horn. However, the small diameter bore requires modding or making the second stage poppet, which might also slightly restrict air flow.
With a centered bore, a standard diameter can be cut and a stock poppet will fit. The disadvantage here is the increased distance from the jet to the intake horn, which will require some sort of air director to get the flow up into the intake horn.
I've been fooling around with a simple tube director. It might have legs.
It's been too cold to spend much time in the garage/shop. We're up for some warm days, so maybe I'll make some progress next week.

I worked on the second stage of the center bore Dacor conversion today. I worked on the cap/lever carrier, and got it set up with a poppet, spring, and an old lever. This centered bore eliminates the interference between the lever and the IP adjuster, but creates the need for an air director. I'm pretty sure the way I'll do this is to make a brass ring that will slip over the top of the second stage cap. The ring will give some meat for threading a hole to accept a piece of tubing or a turned nozzle. I'll superglue the ring on. Of course, it will be threaded at both primary jets in order to give 1/2 turn cracking adjustment. I should have made the cap with this thickness already there, but I just thought of it. I may make a new cap after proof of concept.

I made a little more progress on the venturi tube for the center-bore Dacor conversion. I made a ring that fits around the top of the second stage, to add some meat for threads to support the tube. I cut opposing flats to clear the IP adjuster, and opposing flats to drill the holes for the tube. I want to be able to adjust by 1/2 turns, hence the "opposed" bidniss. Crappy photo, but you can see the 8-32 threaded holes for the venturi tube, and the clearance flats. Here's the ring in position, showing the open hole and how the venturi tube side is aligned with the intake horn. And here is the view showing the venturi tube side. Of course, in order for all of this to fit together inside the box, the ring can't be permanently affixed to the second stage body. The ring has to be positioned and secured after adjustments are done. How I will accomplish this has yet to be decided. I'm thinking that the threads might extend into the second stage body so the tube will hold the ring in place. Another idea is a touch of superglue. Maybe some kind of mechanical holder-in-placer (sorry for the technical jargon!) will occur to me. I will turn the venturi tube next. I'll post photos of it when it's done. I am also going to thin the first stage to box retaining ring to eliminate potential interference with the second stage cap. .

Dang, that's one tight fit, ain't it? It's always fun when you can come up with something new, and then figure out how to make things work JB
