Nice. Also those motor shields are pretty sweet. what'd you do to fabricate them? Just took some K&S sheets and used a bender?
Yes, brass sheet, bent. Steve made it so some of it is soldered together because a piece was too small. They are good for brushless outrunners to keep wires off
yeah I was wondering how people kept the brushless motors from making a mess with those spinning cases. I think you were right though earlier--you're going to have to be real careful with that razorblade of a stern!
Some work today Poured aft, came out decent, had some leaks but survived Barriers removed Solenoid platforms Good clearance for gun parts Back portion limited by servo Fired up the ol printer for a bottle holder, took some remembering but got it working Came out good, I use same style on most builds which is why I drew it up and printed Up angle for freeze prevention Hull 9 pour was at a slight trim, checked level but was slightly off Looking at room Maybe guns tomorrow, pump mount
Not a ton done today. Drew up am printed a batch of solenoid mounts. Came out good enough, test fit here On aft platform Clearer view, hole through middle for zip tie Then started cutting stuff for gun production. I think i need around 18 guns for this build season, so I’ll do most of the production now and then adjust per application later. Here is 3/32 brass for end caps, elbow, and magazine , marked at 1/2” Cut up tubes, two size for low and elevated turrets, will trim as needed Cut magazine and flare unions for mag ends. Dremel was hurting for a bit I prepped the elbows at Marty’s before the holidays, have 15 milled so will get a few more done next trip
Some gun work tonight Set up for mass production, end caps All the parts for the elbow and associated tube Prepping solder, wrap Remove and snip Small diameter Cleaned up tube ends Back feed connection Just add heat Done Now tube And after End cap before After Got 14 elbows done in about an hour Still need to verify unobstructed bb flow and clear air flow through back of elbow, most important step
Hey Kevin, what size tubing are you using for the end caps? where might I get some? did you use a drill press to pop the holes for them? I just got a pile of parts from Strike and have to make some end caps.
K&s brass tubing, 3/32 (OD) found at some ace hardware stores, hobby shops, or grand old internet I use a center punch to mark holes and then a drill with 3/32” bit, pretty simple. Typically have them flared out a bit to make hose attachment easier
Ah got it. yeah that'd be at Hobby Lobby In Rhinelander. I saw some last week. Anything fancy about the drill bit? I've burned the temper out of a lot of bits so far. we talking something like carbide tip?
Honestly haven’t paid too much attention to drill bit selection, historically I select ones for metal. Brass is relatively soft so I’ve never been too concerned. That being said, last night I broke two 3/32” bits that I got from harbor freight for about 30 cents each, so I’ll go back to the $2 bits that will last for a while
Printing and gun work. Thanks to Caleb for the file Magazine time, step by step, I think I made 19 here Had to drill out the fittings to accept the 1/4" tube, went in 1/32 increments but with 19 it took a bit and complete Continued printing turrets Left gun turret Left gun turret finally printed successfully, had issues getting it to lay flat on print bed so had several failures before i realized issue CO2 tube soldering complete End caps soldered
Finished up gun component work Drilled through every hole to verify flow, also passed a BB through everything, then soaked in alcohol to clean off excess flux Gun pistons cleaned up Started working on magazine bending Aft gun Good clearance Now second Friendly stern Good clearance on second end cap With turrets Printing turrets was faster with the need for 12 Turrets have hole for dummy barrel and hole for the mount tube I use, reduced the need to do those steps separately. Four different variations, dummy turret, left gun, right gun, and double. I will bondo some areas of them and put a layer of cloth on sides to enhance visual and bb resistance Worked on forward gun layout, cut away some subdeck for better mounting options. Will start to mount these guns next, looks like they should turn out alright
Kevin, if you wanted to try it out to save time vs bondo'ing every turret, try automotive filler primer. It's high build and typically fills in the layer lines pretty well.
I'll be honest, I have never done it this way before and my solder joints always look like modern art. I am absolutely stealing this for my gun builds! Thanks Kevin for being thorough and documenting what probably is such a tiny silly detail to you. Will really help me out.
Short amount of work today. Made turret holder things to complement the turrets Seems like it will work. Epoxied deck pieces
