I was sitting around one night when I just happened to look at a Tek 6 turret that was laying next to a Big Blast, when I noticed the Tek 6 turret is the same size as the opening in the front of the Big Blast. Right away I knew what had to be done, that turret needed to go into that Big Blast.
Materials:
Buzz Bee Big Blast
Tek 6 Turret (I suggest one that does NOT have cross style posts)
6ish feet of cpvc (much, much less if you use another barrel material)
4ish inches of 1/2" pvc
1 cpvc coupler
1 cpvc street elbow
1 pvc coupler (or whatever you use to couple a Big Blast)
Glue of some sort
Dremel
First start with your turret. I highly suggest NOT using one with cross style posts. These turrets are one solid peice with the posts glued from the back.
Remove the screw from the front and take out the star shaped peice, this will be important so dont lose it. Now remove the posts with your desired method. I twisted off the posts and then hammered out the rest with a metal rod I had lying around. You have now created your perfect rear loading holes in the back of the turret. You will also notice that the rotation mech is attatched to the barrels. This is why you dont want to use this turret if you can avoid it. Huge pain in the A**.
Time to bust out the dremel. Basically cut off everything, try and save as much of the slots that the rotation mech slides in as you can. I noticed these too late, and as such mine are a bit short, well the perfect length, but i wish they were just a bit longer. To remove the rotation mech just cut around the hole the screw goes in and it should fall right out. In the end you should have this:
The second star shaped piece has been stolen from another Tek 6. It's more or less a cosmetic peice on this style of turret so it will not be missed on a stock blaster. Enlarge the hole so that the screw can fit through it.
Cut a length of cpvc, the length depends on your screwdriver. Cut it as long as the shaft on your screwdriver.
Sand down the ends so that your star shaped peices can fit on. Glue them in place, you now have a good length barrel spacer.
Set these peices aside, we will come back to them after we have something to hold them.
Grab the tee and cut the top coupler off. Sand out the hole so that the street elbow will fit.
I found that the sanding drum dremel attatchment is a perfect fit.
Take the street elbow and cut a notch in it so air can still pass freely in the tee. Only on one side though.
Cut a section of cpvc (mine was roughly 2 1/2" it can be longer, or shorter) and glue it into the street elbow. Now glue the elbow into the top of the tee. I sanded them down on the top (tee) and bottom (elbow) so they would fit together better.
Grab your rotation mech and cut off the back half of the teeth-dealies. You can cut off all of the teeth, or leave 2 like I did. This is because the rotation mech with the teeth off is a tight fit in 1/2" pvc and I am not glueing it in, the teeth are just a little added assurance that im not turning the rotation mech in the pvc. Cut 2 notches big enough to fit those teeth in the end of the pvc. Stick the rotation mech in the pvc and cut the pvc down so that there is about half an inch of space behind the rotation mech.
Cut a bit of cpvc, around 1 1/4". Sand down one end so that it fits in the pvc. Fill it with hot glue and glue it into the tee. Now glue on the pvc.
Cut 2 rings of pvc about half an inch long. Cut a notch into one so that it will not hit the tee, glue this peice onto the end of the cpvc sticking out of the elbow. Cut a 1" section of cpvc and sand down one end enough so that the other pvc ring fits. Glue this onto the other end of the tee.
Now for the fun part, the barrels. Slide the turret base over the rotation mech and then slide the rotation mech into the pvc.
Screw the spacer onto the rotation mech and start glueing on the barrels. While you do this, you have to make sure that the rotation mech stays in the tabs.
The main reason the rotation mech is not glued to the pvc is for fine tuning. For the seal I used a bit of arrow foam, glue the foam to the pvc/cpvc on the elbow. To stabilize the turret i cut a bit of the original barrel and notched it so that it fits the pvc rotation mech holder. Foam has been glued to this as well to help put a little bit more pressure on the top. Another thing I did to improve the seal a bit was fill the back of the turret with hot glue.
Cut the barrel off of your Big Blast and slap a 1/2" pvc coupler on there however you see fit.
Cut a hole in your Big Blast shell for rear loading the turret. Close the shell back up and insert the tee into the coupler.
Finished.
No ranges yet, as its too cold and windy to bother.
