Sherwood Magnum - worth rebuilding for SNUBA project?

[Nevek]

I have an old Sherwood Magnum regulator I found in my dad's garage. I am in the process of putting together a SNUBA system and was wondering if this regulator was any good to use. If so, where can I get parts to rebuild it? It will be used to depths of max 50 feet.

The reg is just fine to use. As for getting parts, there are a myriad of places to get o-rings (check out the the online repair manuals to get the correct vintage of Magnum).

Also, the 2nd stage seats are easily made by yourself - see this thread

Enjoy!

I have never rebuilt a regulator before....where should I start reading?

 

[Texfrazer]

go to the frogkick.de website and download all of the sherwood manuals. Then you can figure out which magnum you have and read that manual.

Next, go to Airspeed Press Homepage - Books For Serious Divers and order Vance Harlow's book. Read that, and you'll know more than 75% of the guys doing regulator rebuilds.

Welcome to the dark side.....

Thanks! Not sure I want to spend that much on a book for this little project quite yet but I will look into it. Thanks again

Those are easy regs to rebuild and are well worth putting back in service but there are a few differences in the old Sherwoods to keep in mind. The Belville (cupped washers) MUST be reinstalled correctly and the dry bleed system must be checked and working if the reg is to keep working correctly after the rebuild. It's not difficult but you do need to understand them to ensure the reg is working properly.
