One sec, I'll get the bottles. Basically the ones that @Charley said explicitly NOT to use, lol. I really hit all the branches falling out of the stupid tree on this one
ta-da! what's infuriating is that I had a set of the Marine epoxy sitting right next to it that I was going to use, but then stopped because the stuff was opaque and would block all of the function lights on the board
I found other things to occupy my time. Tapped in the safety pin holes on the sidemount barrels, Hull's painted, added the last two reflective stripes to the bottom of the hull, and I fixed the forward sidemount. The safety pin holes were a real pain since the barrels are fairly hard. Future reference to anyone looking to cut their steel barrels short: cut the other end and leave the stock holes. I burned out two bits drilling it, then got a replacement pair, which I then drilled in a tupperware full of water. The water kept the heat down to preserve the bit's temper, and also contained the shavings pretty well. Painting was pretty straighforward. I'll go back later with black to get the waterline dialed in and clean up the edge. With the little tube back in place, the front sidemount is fixed. I'm going to slap it back in place, and spend the rest of the evening connecting the solenoids to the guns with 1/16 tubing After that.... I dunno. I'm out of stuff. Once the new board arrives, the boat's done. Just need to get a second set of batteries and a charger.
We put a plastic wrap made to go over wires on the mags and up feeds. Without it you will get dents in them and the gun will stop working, BBs always find a way through. I have a big roll of it.
yeah, I took the armor off to work on it, prevent melting, etc. here's the gun in place: All of them are armored up, the barrels too. I'll let you take her apart next saturday to your heart's content and find all of the screw-ups before it goes on the water. I already know you're going to laugh when you see the props
I have used multiple coatings to Waterproof my electronics https://www.ebay.com/itm/MG-Chemica...788399&hash=item3b089f5bda:g:6m8AAOSwhktayaBE and I use this most times https://www.ebay.com/itm/EPOXY-RESI...:CyAAAOSwgn5XE8gZ:sc:USPSPriority!37770!US!-1 my future waterproofing I may add a coat of the conformal coating first then add Epoxy
Thanks Charley, I promise I'll do it right next time and save us all the hassle. Though I would totally pay if you guys cranked out a waterproof model of your board someday
Hmmm, I got some conformal coating and tested it on a smoke alarm board. It sets up but I can scape it off easily with my fingernail a week later. Maybe thats normal. Randy
I'm putting the second coat on the board Charley sent me today. BTW, Big thanks to @Charley and BC for rushing me a board!! it does seem a bit in need of a gentle touch right now, but I imagine the multiple coats he said to use, and the complete layering will make it stronger.
Board's done, waterproofed, function checked, and ready to go Going to take a quick shower and head to the pond. Expect photos by afternoon.
And...... in spite of the water being like a scale typhoon, the boat didn't sink! So. the big take-aways: The pump works pretty well The 1" props do not. maneuvered like a wallowing hog and only had power when I shut off the pump. But I figured out how to limit my rudder and make the 1.75 props work, so problem solved. Speaking of which, I was running the 6 volt SLA battery (my LiFe batteries have one sortie in them for tomorrow and the charger is still shipping), and it looks like I can make the SLA backups work for now by wedging one in with an expo eraser under the straps. don't ask, it works but looks like crap. Battery no move, moving on lol. Deck Sealing tonight!!!! That is HAPPENING. good god, the chop was so rough the bow was getting buried under almost every wave, and I definitely need to stuff a rag in E turret's barbette to prevent infil. The Pump outlet will likely have to be diverted next week over the side because going straight up, the glug is not totally clearing the deck. but we'll see tomorrow when PPB starts popping holes in her. I'd call her operational by the time I go to bed tonight.
May have been my imagination. but there was a slight gain when I shut off the pump. Inversely, it seemed like the pump was running better when the boat was stationary. I will take it back out tonight when the wind dies down with the 1.75 props and verify. I know. it's weird, and likely a figment of my imagination, but figured it was worth mentioning.
6v systems like LARGE gauge cable. The lover the voltage the higher the amperage. The higher the amperage the larger the cable required to do the same work. That last two words are key. These rules all work in inverse proportion and by a factor of two. I. E. Half the amperage for double the voltage and vise versa.
So a 24v system can use a 4x smaller cable than a 6v system. Theoretically. There are of course other considerations. Lol.
