I'm building a prototype butt stock and I bought a couple of type D stocks to play around with. I was just going to send one to JT to make me a type A, but after studying a real prototype butt stock, I want to play first. I know Carbinekid did a thread a couple years ago, but I don't see pictures or real step by step instructions. Does anyone know of a thread with pictures on how this is done? I know that the cut requires filling and shaping. I would rather not waste a stock figuring this out.

Bill, I thought kygun had a thread some time back on how he did one? 6 to 8 months ago, maybe.

Thanks guys, they helps. The first one has some pictures I can follow. If anyone else has a link or pictures I would appreciate it.
|
|
Thanks, I can't remember if I made a post before this one you posted or not.

I thought you (or someone?) did a more detailed breakdown pretty recently (a few months back?) where they'd taken off more of the stock, and rebuilt it using the bottom ridge? Dunno.

I have a template for the shape. Shoot me an email and I'll send you a paper copy.
I cut mine down into the foam more than necessary so I'd get a good thick base to work on. Then it was sanded to rough shape, primed, sanded, primed, finish coated. If you are half decent at body work or drywall it isn't hard. |
|
Email sent, thanks for the offer. I am really looking forward to playing around with a couple of ideas I have to recreate a more accurate prototype butt stock.
|
|
Well, I finished the conversion and it is ready for paint. I forgot to take in progress pictures to post. I need to do a little research on what finish to use before a dip in weave pattern. I'm going to try to dye the butt a brownish shade to get it a little closer to the prototype color. No solution for the Armalite stamp yet. Thought of having a medal stamp made and branding it, but it would be inset instead of raised. I made the front flat and modified a carbine ring to look like the front of the prototype stock.

|
24 hours of soking in brown dye did nothing to the black rubber.
|
|
Ordered a branding iron/wax stamp of the butt stock emblem to try to see how close I can get it. I'm also going to try painting the butt plate dark brown. No replies on the wrap yet, may have to call...
|
|
Are you going to try melting it into the butt, or some other way?
|
|
|
What if you used a 2 part epoxy and made a cast of it, then glued that into place?

Ok, took a couple. This one is a type D, home made prototype needing a final coat of primer, but had been wet sanded, type A in brown and a type B in green. http://i1302.photobucket.com/albums/ag132/58Bisc/guns/E0246F4A-B6D5-475C-97F9-14331D164958_zpszoqdoddu.jpg Type A and the prototype end to end. Note that I cut the end flat and it makes the strigh look shorter. I also thinned out the stock. http://i1302.photobucket.com/albums/ag132/58Bisc/guns/0AFB652D-196D-4CD5-BCCC-D736F340A65F_zpss6lovl6r.jpg I took a carbine ring and cut it down to mimic the original prototype stocks. http://i1302.photobucket.com/albums/ag132/58Bisc/guns/28AA4A43-B2C3-4845-A2B5-57638F56F353_zpslujgye5i.jpg Here is everything mocked up for a test fit. http://i1302.photobucket.com/albums/ag132/58Bisc/guns/BBD67662-1E01-498E-9144-8F071E513EC4_zpsdsho9ii4.jpg Another view. http://i1302.photobucket.com/albums/ag132/58Bisc/guns/C6E46565-0075-444D-B71F-CA32A2EEFB51_zpsum77hip0.jpg Here is a original brown grip with the sling swivel installed, prototype one piece hand guards and the stock. http://i1302.photobucket.com/albums/ag132/58Bisc/guns/4229E0D5-3D43-4F82-9930-A7E650833920_zpsbyey1std.jpg Now for the prep to get them wrapped in a weave pattern and the attempt to dye the pad brownish. View Quote Wow,,now that's anal, matching the ring area. I never thought anything about that. Good job! |

I have an old type D rubber butt plate that I cut off a 607 stock years ago. I intend on burning that one first. If it turns out well, I intend to try to cut it out as a raised emblem and attempt to epoxy it to the stock. That of course would be best case. Worse case I'm hoping the brand is clean and I can at least try that on a stock. It will be about another week before the seal comes in.

I doubt even if we had access that anyone would let you mold one. |

OH, I thought that you had access to that one in the pic. I still think you could do it since we know the shape of the overall butt is the same, lines are easy enough to make and you will have the emblem. Don't rule it out. RTV (room Temp Vulcanizing) molding is a great tool. I used it often in model building. The butt stock shown in the pic appears to be molded from fiberglass? Doesnt look like rubber?

I have plenty of type D cut off ends with but pads for you to practice on. If you want them you can have them. Just send me an email.

I believe you are correct that it is a hard rosin with mat in it. It is brownish in color. I thought of making a mold and attempting to make one from scratch. My issue is that I no experience with mold making.i may progress to that point, but let's see how bad my first attempt comes out.

Matt View Quote Thanks Matt, I'll let you know if I need to take you up on that. I made a flat spot on the stock butt pad after I practiced on the cut off. I'll post a picture later. |

Basicly you build a tray around the pad on your rifle or better yet get some from Matt. Build a small tray and set the pad in it face up and secured to the tray. Get a tube of silicone and squirt it in, on, and around the pad making sure to get all the detail of the pad. Let it cure then remove the silicone from the tray and gently pull the pad from the mold. Now you have the negative. Figure out what you want the new pad to be made from and pour it into the negative mold. Let that dry, then remove. There it is, short of maybe some clean up or paint.
|
|
Hmm, not bad, better than expected. Casting your own is still the way to go.
|
|
Hey now that's what I'm talking about!! Looking good! I am most amazed at the fact you got the butt pad off in one piece, that my friend is some talent and patience and possibly some luck?
|
|
Emblem does look high. Perhaps using a Forstner bit on the butt pad would help to counter sink your stamp? Looking good so far. Email me if you'd like help. I can get some pads from Matt and see what I can do.

I sprayed it with some paint to get a sense of prospective and I agree it is too high. I've tried to make them lower, but they loose detail. I thought about drilling, but what stopped me is that the center of the butt plates is a little lower then the sides. To remove the vains completely, it creates a low spot.
What will really need to be done is to fill in the flat between the vains. Then drill it out, then file it flat, but not low. The next problem I have is that most of the butt blanks I have are not in great shape. I have to attempt to repair them before I start the process over again. |

10-4. I know the peg faces left on lower.Just odd that it switched up.
|

Agreed, I thought the same thing at first. I used this picture to get the stamp made. I think this clear picture came from Imarangemaster, but I have a bunch showing the same thing. I just need to get a model that looks correct to create the mold. The problem is I don't have an artist's eye, it is an engineers. The views are different. My eyes see the different prices very clearly, but bringing them together is much harder for me. I see the tiny details, but when I step back in view they get lost. That forces me to make the smaller pieces and bring them together.

Lookin good. A little vibration will get out a lot of the bubbles. Perhaps a palm sander in the table top where your work is? Keep going and remember there are no failures just lessons learned.
|
|
Definitely an impressive effort.
I love the attitude expressed: there's no such thing as an impossible retro build...it's always just a matter of how much you want it! |
|
I got the bubbles to the top by laying the assembly on a vibrating compressor that was filling. I learned that trick on an earlier attempt.
