I have been thinking about making a very unique feature available to you fellows who signed up to own one of these beasts. Because it is an extremely close tolerance item and also is authentic and functional on this gun, and worth approx. $200, I have decided to let you fellows decide whether we include it or not. Since we promised everyone that the whole gun would not go north of $1,250, we must stick with our promise that you will not owe us more than the $900 that you do now after buying Zulu's marvelously authentic Gun Position No. 2.
This means that we will have to trade the capsquares, worth about $100 for your gee-whiz, super-addition of the completely functional, Eccentric Axle worth at least $200
, which gives you the unique opportunity to raise the rear of your Gun Carriage after shooting, for an easy Return to Battery for Loading once again. You will NOT owe us the difference, just being able to make these close tolerance, complicated, Eccentric Axles and special bearings, rotational axle stops and special, Eccentric Axle Wrenches will be payment enough.
We included these unique axles on our premium cannon, the 100 Pounder Parrott Rifle, M1861 and they were a really big hit with our customers who had fun demonstrating the way the Eccentric Axle lifted the Carriage for easy rolling and lowered it down again for maximum friction during recoil after firing.
The fact is that omitting the capsquares will not be missed by any casual observer, because very, very few heavy Seacoast Guns had capquares, because the weight of the tube held it in place in the half round notch in the trunnion plate. The only guns of this type which needed them were the naval type because of the pitching and rolling of the ships during stormy weather. Lots of the land-mounted guns do not have these items attached, even in museum locations.
No, we can't do both for extra $. In order to meet our schedule, we must make all these cannons the same way for efficiency.
Please let us know soon, because I must convert my sketch of the mounted Eccentric Axle to an engineering drawing so it can be made precisely.
Please let us know what you vote for and why. Thanks.

What the end of an Eccentric Axle looks like on a Rodman 15" Seacoast Gun. KABAR2 wrote a good description of what the two dimples mean in the "The Foundry Machinist Tool, Tool Marks and Tooling Contest"
that we presented several years ago. He wrote, "The two center points are from 2 lathe operations turning the shaft of the axle off center giving it an elliptical or eccentric shape, this would allow the shaft to raise the carriage so the wheels would roll carrying the weight of the gun."
