this didn't make it the first time I sent it. Read on....... ---------- Forwarded message ---------- Date: Tue, 19 Sep 1995 12:11:45 -0400 (EDT) From: Patrick Edwar Moran <pmoran@st*.ud*.ed*> To: Marc Dufour <mdufour@CA*.OR*> Cc: Anthony D Montgomery <amontgom@ha*.ed*>, techdiver@terra.net Subject: Re: Pony gauge, homebrewed dive gear. I made the exact same pony bracket out of aluminum by welding two rounded lengths back to back with a small brace running perpendicular on each side of the juncture. One u-shape is rounded to exactly pony size, and attached permenantly by hose clamps (2), the other side is hp100cft sized and attaches using a BC strap with buckle. This can be removed in seconds (even form doubles), is strong, fully ajustable, keeps the pony approx. 1/4 inch off main tank(s), and cost me about $15 and 15 minutes to make. Nickelrocketry maybe, but $180 is $180!!! ;) Pat ******************************************* On Tue, 19 Sep 1995, Marc Dufour wrote: > > > Well, I am also setting up a 30 cu. ft pony as well.
