So, I was able to get my hands on some plastic sealant (similar to tool-dip) today and re-sealed the interior and internal mount points on Missouri. This should prevent the cat from smelling residue of previous marking. Also, I'm working up a carrier/storage box similar to what Gniesenau had. That way, I can safely store the boat without worying about the cat once again getting access and "marking" the boat as his. Once this all dries, I'll resume working on the electrical refit.

I took a little time to mess around with the barrel bends again. I somewhat accidentally discovered that the PVC glue bonds strong enough to press fit barrels and risers into the barrel bends. This will eliminate two of the metal parts I had planned to use. I also did some test fires through the barrel bends. Everything worked great except the guns seemed to be firing a little soft. I will probably have to wait until the weekend to investigate more.

I've been thinking building some sort of armored harbor for Huntington to park in when she's not needed and I think I may finally have a viable design. This involves modifying a styrofoam cooler by cutting off one end and cutting a hole in the bottom. Then I can toss this in the water upside down. Hopefully it will float and might require some balasting to make it float level since one end was cut off. Either way it would hopefully provide some protection from stray rounds damaging the club's rescue boat. I hope to go shopping for foam ice chests in the next we

I took a little time tonight to knock out some test risers for the Barrel Bends I roughed out yesterday. I am trying to get enough together to test fire some rounds through them by the end of the week. I was really surprised to find that even with the risers loosely fit in they held the barrel bends in alignment very well - even without being bolted in place!!!

I am not going to post many details as I don't know if this is going to work or not. However, I did make some progress making the machined barrel bends today. Plus the PVC glue does seem to be be at least as strong as the PVC itself. So this might just work. If it does then it should trim amost two inches off of the height of Nassau's barrels. I am hoping to install them at scale height. Here are a few random pictures from today.

I took some time tonight to make the holder I needed to make the next-gen barrels on the rotary table. It took longer than expected but I think it will work. This bolts to the rotary table and provides repeatability of setup for the barrel bends. Plus it should hold two parts at a time!

After a recent facebook exchange with Greg McFadden I noticed his February 7 post on RC Naval Combat showing the work he is doing on his SMS Baden. I really like how he integrated the motor mounts into the stuffing tubes. Its basically a two component setup - the first is a bracket that allows him to easily adjust the distance of the motor from the prop-shaft - this makes it easy to use a belt to drive the propellor. It also allowed him to place the motors aft of the stuffing tube (something I am going to also probably need)

This evening I made some temporary mounts for Nassau's cannons. To my surprise the cannons fit at the scale location with room for a 9 ounce CO2 bottle! I was really excited to see everything coming together. Once the snow melts a little more I will have to try placing them in the spare hull and see how well it floats. The weight is around eight pounds so was are already about half I what I probably can allow. (Pictures in post)

This evening I made the breeches for Nassau's cannons. The breech is where rounds are fed from the magazine into the bottom of the cannon's barrels. This blog post will walk you through most of the process for making a breech on a mini-mill and mini-lathe. These steps have been simplified from what someone might do who wanted everything as precise as possible. I am more interested in making parts quickly - this means minimizing setup and maximizing the number of parts that can be made each time a measurement is taken.

This morning I did all the mill work for Nassau's cannon manifolds. The manifold is basically the bottom of the part of the cannon that rotates. It has two purposes (a) it redirects the CO2 to the barrels and (b) provides a way to adjust how the shot sits in the breach.
