Yes, I would want to be careful at this point also. Not sure if you already have threaded rod with proper end to touch underneath cannon with four handles? I will be going to a place in a day or 2 that may have some acme rod, I am looking for some steel. Because of your construction of the carriage being kind of a box instead of solid. A block of wood could be added the width of center piece to give strength. And of proper looking length and height would give you a chance to get the angle correct for a vertical screw and in proper placement for the arc of the cannon. This could all be done separate from any of your already nicely made items and then fitted. Also if this is going to be loaded that a cannon with center trunnions will tend to kick up the back and the barrel drop down. Might need to check into what the barrel might hit when it drops down in front and if a part round block is needed up front where it might touch to distribute the hit. If you want me to look for acme tap and rod let me know what dia. you would want and price range. There are plenty of pictures of the elevation screw on the different civil war cannons including my model.
good point drilling a reinforcement block to achieve proper placement and it will be a drill block as well. that's what I needed. I already have my acme rod and acme nuts. don't need much elevation either way because this a salute cannon only no projectiles, not expecting a big amount of recoil and barrel bounce forward so I'm not drilling all the way through the trail, so as to not weaken wood that is close to a cheek bolt hole. I'm estimating a 12 degree hole angle. may not be right on any of this. but a oak block forward under the tube would be a good idea for sure. If i'm wrong on my thinking, tell me you can't hurt my feeling, since I am just spit balling this as I go. I can't thank you enough for this great help you saved my bacon. Phil

Yes, the wood block could be used as part of the build or just as a fixture to allow you to see the angle and position.
Have included a link to a much more information than needed on your particular build. But is interesting and deals with the elevation screw.

Still think your cannon looks great and looking forward to pictures of this addition.
