I was told that some were having troubles to get in and see this so I thought Id show it in here like this with a little detailed discription with it....
Top left is a shot of the top of the block, This is the size of the internal chamber there... I have to as of yet actually put the brass fitting in yet but that is due to that I want the glass looking as clear as possible, so less to work around without them in yet...
Top right is the bottom of the block, It is an aluminum sheet attached, Im not sure yet if how it is attached will be good enough, Going to test it with some decent pressure before hand of course, and still need to lap it to get it smooth...
Bottom left... It points to where the actual brass fittings will go...
Bottom right, just an angle shot of it.
[Edit] Another note I just spoted, if you look in the bottom left picture you can see what it started out as... just a block of plexi, rough and you can barely see into it, let alone through it as you can to a degree so far with the one Im working on...
