Silicone/nitrile rubber stopper? May be available at the hardware store.

Test plugs for plumbing? They are probably a bit big. I haven't seen any for say 3/4" or 1" pipe

I meant ones like you used in high school chem. If it is one with a hole, using a bolt, 2 washers and a wing nut would allow you to expand it in place.

Finally getting all this stuff together. Does anyone know of a place to get 7/8 UNF type plugs to seal up the 3500psi tanks I have? I've been looking, but coming up empty.
@ajtoady sending me some of his spare cable

I have to check but my plugs I use bsp or jic, ill will have to check which one if interested

Thanks!! I actually ordered some bolts from McMaster Carr that I think will work, haven't had the time to try them out though.

Make sure the last part of bolt thread doesn't bind, may be ok if the shallow threads end up in the oring area,
If not flip a die and run it to the neck of the bolt,

Aluminum circular rod: 3/8 x 36 inches.

18 holes 3/8 inches apart.

18 stainless wires - 8 inches long.

18 pan head SS metal screws 3/8" long

Screws and wire are at Home Depot.

I know this is an old post but with the screws are you using them to try to pinch the wire in place?

Exactly!

I understand "crimp", I don't understand how? I've crimped wires, hydraulics, but never wires to the end of a rod?

Another option - especially for making a whip for the bottom of a tank -- is to get 3/8" aluminum tubing (HD dive dept) and shove the wires up inside a couple of inches then get a long 1/4" ish bolt and hammer it into the tube wedging the wires in place. Obviously the diameter of the bolt is determined by number of wires and their combined diameter.

I like using thin SS cable - pretty aggressive and gets the job done fast.

Good idea as well
