No Such Thing as a Fair Fight
This episode of DoomsdayPreppers Castle was such an eye opener. Brent was so good at articulating and getting his point across. There is not many men anymore, let alone one with 10 children that has strived to leave such a legacy to his family. Koodos and I can't wait for their first season!!
A few suggestions:
Brent: Your Castle:
If you haven’t thought about this,your castle construction is an inexpensive and perfect time to install aFaraday cage into the framing. You whole castle will be EMP free.
Derek: Your Cannon:
Thecannon fuse goes into the hole about half way to the bottom of the bore BEFOREyou add the power charge. It will fire every time. (This is ONLY for standardlight-able fuses). If you load your powder in a bag, put your fuse in at thesame depth after the powder bag, but make a hole for the fuse with anon-sparking pin. Use brass, wood, or plastic, a little smaller than the fusehole.
Derek: Your Steel Trap Door:
Thatheavy trap door is very nice, but if a cylinder hose, bracket, piston cup,fitting, or weld failed, it could fall and hurt somebody bad. If interested,you can easily make a hydraulic closer. You'll need a hydraulic cylinder, (2)90 degree hydraulic fittings and a hydraulic hose. This device will adjust justlike a closer on a storm door. The cylinders can be small, but they have tohave the required length to open the door fully, like your current cylinder. 2cylinders will work better than one, but try 1 first.
Mosthydraulic cylinders have a FLOW VALVE at each end to adjust acceleration anddeceleration. They are technically called cushion valves. It's an adjustingscrew with a lock nut. Look for them when you buy your cylinders. *Use onlyHydraulic rated parts. Air fittings will fit, but will fail and that will ringyour bell good!
Completelyfill the cylinder with oil and purge all the air out like brake lines on a car.Install the fittings. Hook up one hose fitting with a short hydraulic hose.with one end disconnected and elevated, top off the hose and cylinder withnon-freezing oil and connect it so it's a closed loop. The less air, thebetter. Bleed it by slightly loosening the hose fittings one at a time and push& pull on the shaft. Then you will need to add oil to the other end. Youwill get good at this eventually.
Weldcylinder brackets to the trap door, attach cylinders and adjust decel valves toclose slow (hard) and open fast (easy). The valves are designed to be one-way.In the opposite direction, they free flow. One valve should be wide open tostart. It doesn't matter which valve you adjust first, but work with the samevalve on both cylinders if you use 2. Use that wide open flow valve to adjustthe opposite direction.
Glad to help.
