I would like to change that out to something I can unscrew with my hand. A wing nut seems a bit excessive.

- Proven volute technology.
- 1 13/16" dia. 6-blade impeller to create max flow.
- Converging/diverging restrictor to increase efficiency.
- 16mm and 19mm spaced mounting pattern provides motor flexibility.

One thing you'll notice is this pump is quite large. (shown next to a @Tugboat pump for comparison) That's why I call it a battleship pump. I'll later do cruiser and...

I was fortunate enough to have a friend who had a 3D model of Fubuki. He’s going to take the hull and deck, blow it up to 1/72, and send me the files. From there I’m going to prepare it for printing.

I’m probably going to print the subdeck first. I’ve never printed for this, so I’m wondering if any of you have recommendations for subdeck thickness?

I’ll post construction updates here!]]> 3 Fri, 13 Sep 2024 21:54:34 +0000 https://rcwarshipcombat.com/threads/plastic-boats-sheeting-technique.447266/ https://rcwarshipcombat.com/threads/plastic-boats-sheeting-technique.447266/ invalid@example.com (JustinScott) JustinScott

So I've had a Derf hull from Strike sitting in storage for the past several years, and it's about time for the Iron Dog to get on the water.

Big problem though. I have far more experience in dealing with wood hulls and such, and I noticed that the cap rail on this fiberglass hull is high and uneven.

I've seen folks using painter's tape to even it out, but have no idea as to how that tape line is chosen. yes I have plans. am I really supposed to just take a stupid number of...

However, one thing is in my way. How the hell do I attach a plastic printed impeller to the metal motor shaft?? I tried glue once on props/gears & they eventually just fell off & spun in place……..

I have a black base BC pump in my Bismarck. I got it working today really nicely. However, on the left side of the base, there’s a 1/8” hole and it’s spraying out a lot of water as the pump is running inside the boat. There is still a lot of water coming out of the outflow. What is this hole used for? Can I plug it up to stop the spraying of water all around the inside...

Super cheap and super lightweight turrets. (Other than the sander)

Use angled sanding blocks and a hot wire foam cutter. Then a belt sander for shaping.

I am working on a couple of scratch builds and wanted to ask some of the more experienced wood builders a question. For my ribs and subdeck, I cut 1/4" notches so that the pieces can interlock. The notches are not hard to do, but they are super tedious. Does anyone have a good way to cut them out? I was thinking maybe the 1/4" scroll saw sander that Olsen makes might work? This is the most annoying part of the build, so any suggestions would be great. :-D
