What you Need:
- 20mm Conduit
- 16mm Conduit
- 16mm Conduit Coupler
- 25mm>20mm PVC Reducer Bushing
- 15mm PVC Coupler
- Hot Glue + Gun
- Titan (with rocket attachment)
Ok Now onto the Write-up!
First off, get the rocket attachment and cut the grated end off.
and then get your 20mm conduit and make sure you use the end with the joiner on it. and then cut it to about 15cm (you may have to adjust it for yourself.)
Now grab your 16mm conduit coupler and wrap it in E-tape to make it nice and tight to fit in the joiner end of the 20mm conduit. (you can also use 16mm Alu with these and you can get the 16mm couplers from electrical supplies IE: L&H Electrical [in Adelaide] search Google to find one near you) So it should look like this.
Now wrap that end to make the 25mm>20mm PVC Reducer Bushing to fit on it and then wrap that in E-Tape to Make it fit in the Rocket Attachment
Now get your 15mm PVC Coupler and Cut it in Half and then wrap the other end of the conduit in E-Tape so the Coupler Fits Nice and tight over it like this:
Now Wrap the 15mm PVC Coupler in E-Tape to Make it fit into the Rocket Attachment.
(Sorry For Bad Picture)
and Now it should all Look Like this:
And Now put it in Like this (Put the End with the 16mm conduit coupler at the bottom)
And then full in the end with hot-glue. I Had to Cut away some of the E-tape to make sure there was enough space for the Hot-Glue. and it should now look something like this:
and there you go, make a barrel out of 16mm Alu or 16mm Conduit, and you have a nicely couplered titan!
Now if your wondering how this works, here's a small diagram:
So Basically the 16mm Conduit/Alu Slides inside the 20mm Conduit to center and stabilize it and then it connects into the coupler at the bottom to lock it in and make it airtight. Anyway i hope this helps you guys!
