So I am getting ready to purchase a TC Kit by the weekend. I’ve been drooling over this kit for sometime and it is affordability it what sold me.
But as I read the TC thread I’m stumped on finding the proper aluminum tube for the rear grip and its measurements. Can any TC kit owners lead some advice? And how you got the split loom to stay in the tube?
Thanks.
I ordered a short piece of aluminum tube from OnlineMetals and then cut to final length. Fit perfectly. I think it was 1/8-inch wall thickness but can’t remember the diameter. For attaching the loom, I ran long bolts through the handle that aligned with holes I cut in the loom. Low tech but works well.
Is there a measurement for the length of the rear tube from gun box to split loom?
There is. Can’t recall from memory, I think it is less than 10-inches, but it is on here somewhere. There is also some room for personal preference. With the handles I used, I ended up making mine a bit shorter because I thought it looked better. I can measure mine if you like. In the end though, order it long and cut to your preference.
8 1/4
No surprise… CPU64 is spot on. Mine is 8-1/4 inches from top weld to back of handle. You will need an extra inch or so to extend into the body so I went with a 1-foot piece and cut and chamfered the exposed end. The handle should be spaced back about 1/2-inch heavy from the Instrument Bar, which using the TC grip leaves about the same amount of space on the loom end on the handle. Too much space and you won’t easily reach the Intensify button. Too little space and it feels cramped. Let your hands decide on the best position.
As far as I recall, this is what I ordered from OnlineMetals…
6061 extruded aluminum tube, 1.25" OD, 1/8" wall, 1" ID, 1-foot length
Awesome! Thanks man!
Whoo hoo! TC Kit is on the way, good number of thrower parts are ordered. Anticipate build to begin mid-April [SMILING FACE WITH OPEN MOUTH AND SMILING EYES]
Can someone help me understand the front grip twist and the purpose of the two hex bolts at the base of the grip?
As cool as the handle twist is I’m seeing it as more of a personal preference but I’m a little stumped on where the hex bolts come into play.
I see the one keeping the grip attached to the gun body at all time but the other I can’t figure out? This served as a lock of sometime?
Hex bolts? Do you mean these socket bolts with the brass washers?..
If so, for the TC thrower these provide a guide for the underlying metal tube track if you choose to have it twist. If not, they would secure the tube to the thrower body. Probably similar function on the original throwers but I’m unsure on that.
Those are the ones. Thanks for the pic!
Full disclosure, that pic is from my TC build and I don’t want to represent it as “official.” Unsure how what I did compares to screen used packs but you should check if that is a concern.
Looking forward to seeing your build.
I will, when I was building my pack I had gb 1 & 2 playing for references. More than likely I’ll do the same with the thrower build.
I’m going to be as accurate as I can with the thrower build and what my skills will allow me to do. I know some guys go all out with full on accuracy but for me it will be about being accurate on my comfort level.
Sadly it now looks like the build won’t go into full swing until May. My GBFANS order is now estimated to ship end of the month. Blah!
Well, it’s here!!!
TC Kit arrived today and it’s a beauty.
Most of my real parts are coming next month but this will give me plenty of time to work on the barrel extension. I’ve been working on a few idea which I’ll prototype before finding a successful one.

Oh look a channel already is on the inside!
Good luck! TC’s kit is a thing of beauty and will deffo compliment your build well
It’s begun
Looking great! As a suggestion, you might consider using black flat socket head screws for the thrower V-Hook. Like this…
Please be careful when posting future updates, to post your image links on separate lines, rather than one after the other on the same line… as it ends up stretching out the forum. 
@bishopdonmiquel I’ll consider it but doesn’t really concern me at this time.
Thanks though!
@kingpin I’ve tried but the image uploads do not work when I try to upload from my computer. My phone/iPad works best.
Wow, this barrel extension in a TC kit is difficult to figure out.
I probably have spent at least 30+ hours trying to figure a simple way to make the barrel extend and stay in both extended and retracted positions with no luck.
I picked up a 1/8 inch steel rod from my local Home Depot and 1/8 inch (I forget what it’s called)
To make the extension bar, that was no problem but making it function has been a PITA! I don’t have my GBfans wand kit yet but I have a feeling that maybe I should hold off on worrying about making the barrel extend until I have the innards. That way I’ll see how much limited space working with.
But the kit is coming along nicely. I’ve pretty much assembled the gun box and front handle.
I did discover something that might appeal to some builders of this kit.
The barrel twist can still be achieved without having to drill into the aluminum tube; however this also means the front grip (TC kit option B) has nothing to secure it to the gun body, but I personally like this idea more than gluing the short aluminum tube to the grip.
In an older build thread from another member of the forum one of the screw holes was utilized.
So I decided to drill and tap this hole.
I am able to twist the handle with no trouble and if I don’t want to use the twist I can simply screw the bolt against the inner tube so it doesn’t move.
