Aloha everyone, I have a Sherwood SRB3200 with the replacement piston. By replacement, i mean that tbe piston seat is peened into the end and when it wears out, the entire piston is replaced with a new one. The regulator currently works fine and locks up as it should. However, should the...

Finally getting around to servicing my DAAM. I got it on EBay for a decent price and it looked to be in okay shape. So far, I’ve dissembled it and will be giving it a vinegar and water bath. No real surprises so far. Removing the clips was a PITA, so I’ll be replacing them with a retaining...

Aloha everyone, I was given a Scubapro 109 second stage that was headed for the trash heap. Basically, the adjusting lever would stick in the up or down position. No springing back when pressed down. Try as I might, I could not get the lever to function properly. I tried various different...

Recently, I obtained a non working Calypso J first stage from the mid 1960s. In my first attempt to repair it, I cleaned all metal parts in vinegar water and changed out all o-rings. I also removed and flipped the teflon seat. I cleaned and replaced all rubber parts on the J portion, but kept...

Hi there. Just finished cleaning and rebuilding a US Divers second stage octopus. Pretty straight forward, clean and breathes just right. Only thing is, on exhalation, the octo honks like a Canadian goose. What causes it and how can I make it go away? All suggestions welcome. Thanks.
