UPDATE: Due to Photobucket squashing third party hosting, I had to attach pics for each step and post them at the bottom of the page. Just follow the numbering and you should be just fine. Sorry for any inconvenience. Good Evening friends, i'm throwing my hat in the ring with my version of TR Doublecross' hand mod. This one is going to be a little more advanced, but i've provided enough pics and step by step (I think lol) that even someone new to modification of their TF's should be able to accomplish. Allow yourself about an hour for this. So, here we go.... What you're going to need. These are essential tools most of us here in the Radicons most likely have already, but if not, here's the rundown.. 2 Doublecross figures A dremel, very indispensable tool and an attachment for just about any mod job ATTACHMENT #2 A small drill bit set (1/16, 3/32, 7/64, 1/8) #11 Exacto Blade Pen Vise 8 mm piece of styrene tubing Exacto saw 1/4 Pin Punch Flush cut pliers A hammer Junky roll of tape ATTACHMENT #23 Poly unit start set #1 (2 ea) they are the pieces in the bottom right corner of the set, here's a link to it from Hobby Link Japan (it's for Gundams) Poly Unit Start Set #1 (Renewal) ATTACHMENT #4 STEP 1) Dyke off the both wrists with the flush cut pliers on figure 1 head and all and cut away the wrist plastic, you should end up with something like this... ATTACHMENT #5 STEP 2) Dyke off the head and lower jaw on both wrists of figure 2 leaving the wrist connector. You should have something like this when done. ATTACHMENT #6 STEP 3) Get your Gundam piece and your 8 mm styrene tube. You will have to cut the Gundam piece to fit in between the jaw on your Doublecross head with your Exacto blade. Carefully hollow out the Gundam piece with a 1/8 drill bit until your styrene tube piece fits in it and cut to fit. Once the styrene tube is in the Gundam piece and you have them cut to fit, carefully hollow out the styrene with a 1/16 drill bit so that you can push the head pins into it. ATTACHMENT #7 STEP 4) Here's where you use the hammer, pin punch and junk roll of tape. I put the Gundam piece in place and with the jaws spread open I gently but firmly tap the pin into the Gundam connector on both sides. Here's what this will look like. ATTACHMENT #8 STEP 5) Take the arm pieces and carefully (and as straight as you can) cut the wrist like in the picture with your exacto saw. The reason for this is for clearance and stability when inserting the head into the arms when the mod is done. ATTACHMENT #9 Here's what you should have when done ATTACHMENT #10 STEP 6) Next, take the pen vise and use the 1/16 drill bit to drill a hole all the way through the to the first section of the arm. Use the natural lie of that section to carefully line up your insertion hole. ATTACHMENTS #11 and #12 STEP 7) I then use the dremel with a 3/32 drill bit to make the hole in the arm big enough for the post from the Gundam piece to insert into the arm. Have a 7/64 drill bit handy in case the hole is still a little too tight. I can't explain why, but one arm was good with the 3/32 bit and the other needed the 7/64 bit. Here's what it should look like, don't overdo the drilling, just do it enough to fit the head post. To ensure a proper fit, do a few test fits. If you do overdo it, you can always use a little super glue to tighten up the hole and post later ATTACHMENT #13 STEP 8) Clean the arm up to your satisfaction and insert your heads into their respective arms and Viola! Nice and tight wrist rotation for your TR Doublecross! ATTACHMENTS #14 - #18 Hope you all found this helpful, and as always, if there are any questions please feel free to hit me up. Take care and God bless my friends!
