OTW NACKEN BUILD THREAD HMS Neptun

[ffr2608]

Restarting this build since there was a long delay. Picked up this beautiful hull from Bob Dimmack of OTW Designs. The kit comes with the hull, planes, snorkel and the monstrous, 5 bladed prop. I will be using a custom WTC for the build but Bob provided the motor and mount that he includes in his custom tubes. I decided to model the HMS Neptun since it is now being made into a museum. Some really nice photos of her during the restoration and fitment for museum life.
First shots show the cradle and upper hull bonded to the lower. I am also starting on the tower detailing when I get bored of the mechanics. More on the tube and running gear later.

Getting the tube reassembled. Location is almost there and the linkages are next.

Reassembly of piston tank. Plan to do a check on the operation this weekend. Calculated the volume via foam block, all parts above waterline and a pool.

A couple shots of the progress. Linkages are in and very stout. Also started the limber holes. Much less to to compared to the WWII stuff but still a real pain.
Only the first round so they will get cleaner with time.

Darrin,
Very nice! Who made the piston?
Peace,

Got the limber holes squared away and took some shots. I really love the proportion of this boat. Short and stocky! Internals are slowly being worked out.

Still waiting for some final wtc parts so I did some detail work on the tower. Railings are in.

The tank looks like a variation of the designs published by Lothar Menz.

They're proven and very reliable, and can be adapted to any size of boat. I have details on how to make these if anyone is interested, I translated the text into english and added a couple of extra notes to help builders. You will need a lathe to machine the parts, but nothing is very demanding and it's much cheaper than buying ready made tanks e.g. Engel. The chapter in Norberts book is also helpful for choosing motor power/wattage.

Still waiting for parts to arrive so I tackled the nav. and stern lights with acrylic. Also put the periscope deck in to start mounting the goodies. My current plan is to have everything in the down position except for the attack periscope. I like to have multiple scopes with small breakaway cuts. Our club is filled with boaters who do not look for the subs.

Got the flag mounted and touched up some of the flaws. I am also working on a plex spray deflector for the bridge. Does anyone have info on the bridges of the Swedish boats? I thought I saw a photo before in some sort of red color but could be wrong.

She's definitely a good looking boat, Sir!! Wonderfully done, ffr2608!

And, yes, Subculture! Would be most interested in your piston tank information!

The forum won't allow me to host a file that size. It's not huge, just a three page PDF. I can email you the file if you Pm me your email address, or you can download it on the Dive-in Facebook page, if you're a member of FB.
