Lots going on at the Drydocks over the last few days!
In conjunction with OTW, we're happy to announce the release of our new 1/96 Russian Oscar II kit. The master patterns were created by Kevin McLeod and they are amazing. The model measures a massive 1613 mm ( 63.5 inches) with a beam of 190 mm ( 7.48 inches). Layout drawings are included. I now have the model queued up for a prototype build in order to create instructions. If you are an experienced builder and don't need a walkthrough, it is up and ready for purchase on my site here.
The Hunley is coming along nicely! I may throw in the towel trying to get the authentic rudder linkage to work. I gave it the ol' college try, but that setup is actually really dynamic with a lot of moving parts. I elected to go with a conventional linkage, which is working perfectly.
Picking away at Typhoon. Lots of sanding for a perfectly smooth finish from the slightly grainy texture that the printing netted.
The prototype cylinder is nearly complete! I encountered some issues getting a perfect valve built for opening and closing the snorkel air intake. I had a revelation last night that I feel is going to be ideal. I'll give it a shot today.
Once done, this will get installed in the Hunley.
The 1/6 Delphin first layup is in the molds and we will be de-molding this morning. The mold is symmetrical top and bottom, so one mold handles both.
This is the cylinder that I'll be modifying for use in the Arkmodel Type VII buildup for Ed. Bigger than the "stock" 2.5" unit with a stubbier tank for better water control.
This was a weird one... I had an OTW cylinder come to me for refit. The owner said that the motor was "broken" and wouldn't spin. It just "grinded". It turns out that the seal assembly was completely melted and fused to the stainless drive shaft. I have NO IDEA how he did that. I couldn't figure out a way to do that if I TRIED! At any rate, Jason and I disassembled it, cleaned it up, machined new clean faces to the parts and installed a bigger seal. Working perfectly now and I'm pressure testing it this morning.

Not sure if you’ve been following my posts in the torpedo section. I wasn’t gonna let this cat out of the bag until much later but the reason I’ve been hell bent on developing the torpedo launcher architecture that I have been sharing is it is capable of launching more than one type of munitions with the quick easy swapping of a couple small parts. In fact two types of torpedoes can be loaded at the same time Depending on how the tubes are configured. The electric counter rotating prop, piston launched torpedoes with no bubbles would be stealthy and the gas propelled torpedoes would just be fun for the reasons you pointed out. There you have it. Had to solve the electric torpedo first.

That said, I've already got functional 48th gas torpedo prototypes. Gas weapons are cheap, fast, easy to produce (and they make such cool bubbles when they fire!).
Most of yesterday was spend on customer orders and further assembly of the MKIII SubDriver assembly.

What have you got in mind for adding torpedoes and launchers to that type VIICLeave a comment:

Standard cylinders run the linkage straight out the back of the unit, typically attached to a rudder arm. I could tear into the bulkhead and re-mount the servo, of course, but customers won't have the expertise to do that, so I want to keep the standard arrangement and work out a conversion of linear movement of the linkage rod to rotary movement of the rudder arm.

Confused. A standard servo is already a rotary motion. It becomes a linear movement when a arm and linkage is attached to it right?

Why try David Merriman's technique with the 1/72 Gato's bow plane retract/deploy mechanism. It converts the servo's linear motion to a rotary motion. As I recall the Hunley's rudder was actuated by a vertical swing arm.Last edited by redboat219; 10-21-2020, 12:23 PM.Leave a comment:

Might want to check these out... lots of them on ebay.
