New 3D toy w/ Pics.........Martin shoot through custom

Some of you have heard me mention the 3D bow I am building. Well it's not done yet due to some mistakes I made in specifying equipment, but it is almost there........

This year I decided I wanted to customize a bow that would fit the exact specs of what I wanted in a competitive 3D bow. Afterall, that is one of the huge benefits of Martin, they will gladly customize and build anything you want through their custom shop. I have monkey arms for my height. I have a 75" wingspan and am only just a hair short of 6' tall. Because of this, I don't need a speed bow to get acceptable speeds for 3D. I like the slayer and shot one well in Harrisburg, but really wanted something with much less reflex in the riser for more forgiveness. For most people the slayer is a perfect 3D bow, however I wanted something slightly different. I like the Scepter 4 riser used in my indoor bow a LOT and I really prefer a 37-38" bow for 3D and outdoor use.........the scepter normally comes 43" ata using the 17" elite limbs. I also think the Scepter has one of if not the best grips on any bow I have ever shot. It is very comparable to the Apex series of bows by Mathews. Plus now I can have a bow with the same grip for all forms of competitive archery.......a big plus for me.

The bow I am building contains the following parts.

Black ghost flame Scepter 4 riser
14" Mag limbs
Nitrous X cams
Barnsdale doovawappi cable spreader system
Gibblet string/cables

I originally ordered a C base nitrous cam for the bow because the B base was only supposed to go to 29.5". My draw length is setup right now at 29 13/16". I didn't realize that the cable spreader system for the shoot through system was going to shorten the cable length and thus lengthen the draw length. No matter what I did the other night when assembling components the bow was 1/4" long for what I wanted. This is good and bad news. Bad news is that it will be another week or so till the new B base nitrous cams and string get here to correct this problem. The good news is that a B base nitrous cam is smaller in circumference so there will be more cam rotation and less brace height.......i.e. more speed. This will allow me to shoot it at a lower draw weight and get acceptable 3D speed. I should have all the new parts to get it shooting by early next week. Final specs should be around 37.5" ata, and 7.5" brace height. At my draw length at 5gpp and a loaded up string it should do around 310 or so...........I won't be shooting it that fast though. I expect to shoot it around 285 with a X-cutter arrow.

Final parts list for the bow completely setup is as follows:

Scepter 4 Mag/Nitrous X - 29 13/16" draw, 65lbs
Gibblet string/cables
Barnsdale Doovawappi cable spreaders
Copper John Deadnuts 2 Competition sight
Doinker Carbon Elite 11.5"
Trophy Taker Spring Steel 1 hole
(ASA + Local 3D) 351 grain GoldTip X-Cutter Pro's w/ Blazers + 90 grain glue ins
Carter Just Cuz release

Here are pics of what it looks like now. The new cams will look just like this, just smaller in size a bit. Pics don't do the bow justice........

Many thanks to gibblet for helping me to make this bow happen. I really really appreciate the help! ;)

Black ghost flame riser:

This pic shows the shoot through cables and barnsdale cable spreader system......i.e. no cam lean or limb twist or torque on the system from wrenching the cables over to a cable slide. Straight shot down the pipe from full draw to static. The spreaders let me get a fletched fat line cutter shaft like the X-cutter through there with fletch clearance.
