Hi guys,

I am building one of AMT's old D8's for my father. This will be part of a really long build diorama that I am still sourcing parts for. I have the D8 but am still trying to track down parts for the Chevy Bruin mechanics truck that I want to build to replicate his 1:1 truck.

In the meantime, the D8 is just about done but I would like to add 2 additional rippers to it. The kit has the provisions for a tripple shank ripper but only 1 actual ripper comes in the kit.. Does anyone know of a source for a couple extra?

I recently purchased a resin molding kit from HL but I have yet to open it and I am a little nervous about how well it would turn out especially on something I am building for my dad. I want it to look perfect and haven't had any practice with molding.

Is there anyone out there that I could send the original ripper pieces to and have them cast a couple extras for me? Does anyone do that?

If anyone has any pointers I would greatly appreciate it.

What do the rippers look like, can you post a picture of them? Could they be done with a one piece mold or would it have to be a two piece mold?

I dont really know for sure about the 1 or 2 piece mold. I dont have much experience in that department. Here are a few pics. Let me know what you think and thanks for the reply.

You might want to post this in the reisn section, the ripper doesn't look too bad but that rack is pretty complex. They guys in the resin section would be able to help you better.

Thanks man I appreciate it. I wasn't sure where something like this was supposed to go. I'll put it over there and see what I get.

Well I did it! I was able to cast those pieces with some degree of success. The model now has 3 rippers. They aren't perfect but good enough for this build and my first attempt at molding resin.

I doubt I will continue experimenting with resin molding. It's way too expensive for the products. It would have been cheaper to have bought 2 more D8's and then I would have all kinds of extra parts and 2 more models! Oh well, I learned something and had fun doing it.

Here's a few pics.

Looks like you did a great job at casting resin for the first time
