I didn't describe much about the handles because you can probably figure them out on your own. You can use gate handles for a super cheap solution. The truth is, once you get this in the water (and hopefuly close to neutral), it can be steadied with two fingers. The motorcycle style grips I have are overboard. They are made of 1/2" schedule 80 PVC nipples with Bell bicycle grips from Walmart. They are glued to a 1/2" male street L, which threads into half a threaded female adapter which is glued to the housing. Everyone is amazed that this glue joint holds up and so am I. I actually made a concave in the end of the adapter so that it made full contact on the housing. I roughed up both pieces thoroughly and used PVC cement. I added about a 1/3 pound of lead shot to handles for trim ballast and it actually makes the housing just slightly negative. I would actually remove a bit to make it neutral but I epoxied it in.

Before painting, it's a good idea to run a bead of 5-minute epoxy at all the joints. That is, inside and outside the Acrylic to PVC joints and even the latch ring to housing body joint because if water gets in here it can make it passed the O-ring.

The paint is just rustoleum. Lightly sand the PVC first, apply a primer, sand again, 4 light finish coats. It gets really beat up anyway so you might want to leave it white.

Finally added a length of 1/2" wide webbing and spring clip to keep the housing with me during rough seas. The additional female adapter glued to the bottom of the rig is for an arm to attach my light cannon.

You didn't have to use marine paint? Even for salt water usage?
