    Nicely done on the jig work. No lathe no problem I see. Looks like a well thought out approach to the problem.

    Started working on my turret drive system this week. I was using aluminum as my base and didnt get the results I was looking for. next design will be out of lexan. The chain drive looks awesome though.

    Built second set of jigs for mini me turrets. I used the same technique only smaller scale for BB's. Please note the barrels are there for effected. They will be replaced with stainless steel apon final assembly.

    I'm impressed, to say the least. I'm looking forward to seeing more work.

    I'm curious about your barrels. I notice you have the bend in the barrel as part of the barrel riser, with a flexible joint for depression just after the bend. Traditionally the flexible joint is located before the bend. Do you have any particular reason for the difference? Does it provide better depression or better alignment in the flexible joint? Do you think it will allow much slippage over repeated firings? Will it change the torque the servo needs to depress the barrels? I'm not saying it's bad, just that I've never thought of doing anything different than the traditional arrangement (nor have I wondered why the traditional arrangement is used).

    I dont know how well they will work yet. But to be honest the placement of the joint is to give it a more realistic look . The barrels will apear to move not the hole turret top. Purely cosmetic I not sure it will give any advantage it does in fact present alot of obstacles. And if it doesn't work I can still correct it with the old way. It should put less pressure on the barrel tips and more pressure on the base due to the location of the bend of the barrels. Just a theory.

    I'm interested to see how the flex joints work. I was planning on doing my small cannons like that, but my reasoning was to make it flex easier since my cannons are such a small diameter that to get the rule required barrel spacing, the risers exit the cannon in an arc shape when viewed from the top, making depression much more difficult.

    The main reason the bend is incorporated into the barrels in the traditional version is because the metal distorts after repeated firing.
    It's simpler to replace the deformed bend and barrel than it would be to replace a curved riser.

    Nice work on the Decking and the 3D plane in the stern bay is very very cool.
    What size drive motors you are using again?

    I'm using 770 s on the engines plenty of torque. Speed isn't the issue max speed on this boat is 40 sec in 100'. Sence this is my first ship I am kind of playing it by ear or trial and error. so do these catapults look to cheesy. Should I scrap them and try again or keep them till they get destroyed in battle before rebuilding ?
