As a follow-up to the the plumbing aisle mouthpiece, I would like to share with you all another "Just for the Hell of It" mod I'm working on.
The idea is to replace the Dacor doublehose second stage and lever system with something more efficient. I have made several different DH conversions and mods, with good success, using a Trieste style second stage and lever. I thought the Dacor could benefit from one, so, hoops were jumped!
I had a bit of inspiration in the early hours this morning concerning a stumbling block, and decided to see if it could work. I won't go into all the issues, and the ins and outs of it all, but I did make some major progress on this today. I'm pretty sure that it's all worked out, and will be successful. It will probably be the best breathing Dacor DH reg (with the exception of my Dacor Olympic 2020) ever. Not a high bar... Unlike the Olympic conversion, this one is installed in Dacor boxes, not Mistral, or FX boxes.
I have a C-2 valve body that was drilled and tapped for LP ports (badly, and not by me), which I use for experimenting. I cut an offset 5/8" bore into the OEM second stage bore on my mill, and threaded it to accept a custom LP seat. The seat is screwed down into the bore (with an o'ring under it) with a custom tool.
A simple nipple is the poppet guide and is screwed down into the bore.
A second stage cap is then screwed onto the nipple. Cracking effort can be adjusted via the cap, and/or the nipple.
The spring mount, the top box and the HP/body gasket had to be cut for the 5/8" nipple. I will have to drill and tap some screw holes on either side of the nipple to compress the body gasket. This isn't a plug and play mod, by any means!
I think it's going to work well...? Pool test to follow!
