Had good luck out here with both the 3d printed twins in the duca and this particular design. I am building a new printer primarily to ease testing so I can more readily make them. My Provence is going from one traditional, one hybrid twin, and one 3d printed side to all 3d printed this winter.
yeah, I'm just glad that @GregMcFadden set everything up to make the testing possible. we'll put them to the test. Unto the anvil they go.
Tiny bit of progress. Round 2 is a lot quicker because I could trace parts from round 1 Shafts came out good Servo mount I cut with the first one Will need to beef it up, plan for weekend is to get this and the deck in
Progress on 9, almost caught up Deck rim Fed deck rim and deck marked Cut and sanded Borrowed aft deck Epoxied together Cleaned up, ready to go in Rudder servo mount in as well
Looking spiffy... By the way, thanks for the work on the ballots - being club secretary is like work or something. Still beats being treasurer, though.
Thanks Chris! More progress on 9 Pump outlet Prep for deck install Clamp pic. General idea is to sandwich the deck from top and bottom with wood to set the correct height. Deck rim was warped so this method was key, and something that would not work without hull cut. Glad to get the most complex epoxy job done, all down hill from here Came out good, used extra filler so not a ton of gaps to fill in Filled in gaps tonight. Will trim excess and clean underside Will make up aft deck piece, cut barb holes, maybe barbs for both hulls
Cut off excess Looks much better post dremel Magnet holes, brad point bit for tightness Have to lay out magnets for easy assess while epoxying Use channel locks to squeeze magnets into holes, taped teeth for epoxy removal Deck rims sealed up Magnets in, I check polarity one at a time Deck pieces Plan for barbs tomorrow
those are 1/4X1/16 neodymium mags, right? What diameter bit are you using that you need to pop them in like that? I'm drilling the holes with a 1/4 router bit and they drop in pretty floaty, which I don't like for what I am sure are the same reasons you go for a tight squeeze.
They are 3mm x 8mm, I use a 5/16 Brad point bit So far so good, no losses yet on any builds. They can’t be pressed in by hand, but the pliers do the trick
Short amount of work, post epoxy looks good Twins Barb holes in 9 Cut barbs (bahhhhbs (Boston accent)) for 1 hull, finally picked up a piece of abs vice pvc. Seems more flexible, cuts fine. Dry fit here, need to cut the wings to fit over deck rim after I epoxy them in Probably won’t get much done for next two weeks, coming along nicely though
Back to work today. Spent a while planning water channeling but no real progress. Cut the barbs for hull 9, then worked on making the aft deck piece reinforcing 1/16 fiberglass is too flimsy on its own, so 1/8 ply and 1/4 square basswood, tracing circles here Prep underside Grind bottom of abs for better adhesion Dry fit, gap for pump clearance Epoxied Brushed out excess on forward deck piece Plan to finish these off tomorrow and get water channeling poured in both hulls
Aftermath of epoxy job, came out good, deck pieces a lot more rigid Figuring out water channeling, looking at component placement Tracing it out, 2” baseline Wider in stern for pump access Can start playing with gun configuration, checking where I’ll need clearance underneath Making forms for water channel Marked intended height to pour too Bow Trimmed wing turrets down Quick dremel job Working on forward facing guns to see how trajectory would work. The ruler is to see where impact would be at water surface, wing turrets look do-able, checking inboard Duals probably in one of them. B turret would be good for a single gun, duals probably would not be able to hit where desired Poured the feather lite. Interesting stuff. Top layer looks dried up but dissolves when mixed. 3/4” high in bow area, will be 3/8” midships and up to motor mounts Spaces for bottle to fit, will add neck cradle to have a slight up angle on bottle to prevent freezing Still could be cleaned up a bit, but overall was faster to the end product Need to do aft portion next
Marked aft portion on 1 hull Should get hull 9 done tomorrow, and mark two small areas aft of motors to serve as solenoid holders
Got hull 9 prepped, finished aft barriers. Will make more sense once pour is done in morning Once that was done shifted to piston drilling while at the Hayes shipyard Got 8 done with no failed bits. Hope to get to gun construction this weekend Steve was sheeting tonight, pretty much operational Ready for sea trials. Could use some turrets and superstructure, nudge nudge haha
