PRID Bulkhead Mod – Wrist Fix

Regular readers here already know I’m a big fan of the Transformers Prime RID Bulkhead, and use it in Classics. It’s a great mold, but it does have a bit of a problem…

The hands don’t fold out all the way.

This isn’t as bad as it was on Animated Lockdown, mostly because of the shape of the forearm, but it’s still a problem. Bulkhead’s a brawler, and how’s he supposed to punch someone with his wrists on angle?

It doesn’t look bad, but it could look better.

And it’s an easy fix! This mod guide will show you how to get your PRID Bulkhead pounding cons with stouter wrists, just by trimming a bit of plastic.

The first thing you’ll need for this mod is a Prime RID Bulkhead. You’ll also need a screwdriver and something to shave down the plastic with. I’d recommend using some flush cutters, and then trimming up the rest with a sharp blade.


Step 1 – Take Apart Bulkhead’s Forearms

Unscrew the screws and pop the forearm pieces apart. The arms aren’t glued together, and there are no pins to worry about, so this should be easy to do.


Step 2 – Trim Plastic

In these pictures I’ve colored the parts that need trimmed in red.

What’s getting trimmed is just the first ridge on Bulkhead’s forearm\wrist. Use the second ridge as a guide, and cut most of the way up to it.

You’re not going to completely cut off the first ridge, because the post that the wrist is on extends partway out to that ridge on the top and bottom. Look again at the before and after picture to see what I mean.

Hand Positions.

Notice that the part were the back of the hand folds is trimmed, but when it gets to the post where the hand is connected, the first ridge is untrimmed.


It’s also best to start with the top forearm piece, because as you trim you can slip the hand on the post and check to see if it needs trimmed further. The second ridge needs shaved down a bit on the inside for the hand to fold out all the way, so use the hand to show you how much it needs trimmed.

Trim the top forearm piece first.


After you’ve got the bottom piece trimmed, you can see how much to trim under the second ridge by putting it together with the top piece and folding the hand out.

Once trimmed, the forearm pieces should look something like this.

The detail on those images has been sharpened, so they’re not as rough in person. With cut plastic like this, if it still looks too rough a fine grit sandpaper can be used to make it smooth.


Step 3 – Reassemble Bulkhead’s Forearms

Put the arms back together on the upper arms, and screw in the screws.


This isn’t a hard mod, even if it might look tricky at first. If you have a PRID Bulkhead in hand, it should be easy to see what needs trimmed, especially if you take apart the forearms and compare them with the pictures.

And once you’ve done it, Bulkhead looks a lot better doing what Bulkhead does best, fitting in with Classics!

And also smashing stuff.



I’d also like to note that my friend OP2k5 from TFINO did a similar PRID Bulkhead mod. He also gave Bulkhead a kickass gun that he made from a Trigun figure and some junk parts.

  1. Great mod Matt, while I wasn’t bother on how his wrists looked, but your mod makes them look a whole lot better. I better start looking for my *looks around* screwdriver kit and blades.

  2. Thanks! And yeah, this isn’t a mod that fixes a huge problem or anything, but it does improve him.

    I think it bugged me more because he’s been on display punching Lugnut, and with the wrist angled it didn’t look as cool.

  3. I miss the good old days of modding. “First you get a box.”

    Bulky can now smashinator to his metal pump agitators delight!

  4. Glad you liked it Bosch!

    And the more comedy based mod guides might show up every now and then, but they do take a bit longer to make. I know there are people that prefer both kinds, but honestly I haven’t felt too much like making them because I’m working on more important book stuff. :)

    But rest assured, if there’s a transformer that needs fixing bad enough that I bother with it, I’ll post a mod guide here.
