    well guys and gals
    here is a follow along tut for creating your own pmop



    lets start
    1.making the big bot arms -
    [​IMG]

    [​IMG]

    the big bots arms dont have any articulation so i wanted to make them articulated in the first pic i just removed the fist in order to install some hand ( i used ones from hlj made by kotobukiya ) so i cut the fist with my dremel tool (used a disc cutter) and install a female ball joint (the hand has a male ball joint ),drill a hole where the fist was,and fit the f ball joint .
    for the elbows i used a joint from energon inferno(f$%k what an ugly mold :)  )
    in the second pic there is a teal colored joint that i think belonged to his arms (eventually this joint went to the lil bot knees) i take pics of the joints i want to install - when u seethe pic on the comp screen it helps u realise proportions and such .
    on this case the joint is too short and wont mimic normal elbow movment .
    so what do to?
    cut the pseudo elbow segment and try to fit a joint there, the part is hollow so there is plenty of room .
    secure the joint with some epoxy glue and then epoxy putty .

    [​IMG]
    final :
    i painted it flat black and dried brushed some silver and chrome on it
    [​IMG]

    2. big bot legs
    this brickbot didnt have knees - so i used rid megatrons arms in order to substitue
    this is a bit tricky mod cause it involves lots of putty work .
    take the arms from rid megs -u'll need to save those ratcheting white clips for later
    cut the bigbot hips and send them down so u'll have "2 halfs " of hips and glue those on the arm , pay attention to match the upper part of megs arms to the upper part of the hip .
    [​IMG]
    it will b better is u fill the hollow part of the cut hip with some putty (so u'll use less glue ) u can stuff it with putty and press the arm inside .
    [​IMG]

    on the trailer part u'll need to remove some pegs but leve the front one
    [​IMG]
    [​IMG]
    [​IMG]

    tadddhhhhhh knees
    whats cool is that the purple part of the arm fits with no pro inside the actually u still retain the normal length of the bot .

    now u need to fill the gaps with putty and sand them smoooth

    final
    [​IMG]

    3. connecting the new hips to the body
    sorry that i dont have pics of how i did mine but basicaly u need to remove some of the grey part of waist pice ( not the white waist piece ),snug those ratcheting joints in side and glue them with epoxy glue ( super glue wont hold those )
    neat trick - glue first with super glue -just for checking if all sits right , super glue can b pulled if excessive force applied , only when u are satisfied with all glue them with epoxy .
    [​IMG]
    [​IMG]

    now u'll have something like this
    [​IMG]

    final
    [​IMG]

    4. big bot head
    a LED was installed inside the plastic in the red eyes is thin enough to show the light
    [​IMG]
    there is a square compartment in the bots head to fit the microswitch
    [​IMG]

    i cut the head from his base and puttied the cut .
    a long ball joint was glued in and a female ball joint was placed in the base ( the attachment of the head to the cab).
    i covered the ball joint with a random spring and added 2 plastic tubing to mimic some electronical wiring .
    in the critic about this custom people mentioned that the new neck is too long ( and i agreed) so just fit the female balljoing as low as u can to avoid the mistakes i did :) 
    [​IMG]
    [​IMG]

    i removed the peg that connects the base to the cab and replaced it with a rare earth magnet . this is a place for some paint chips and so and this will ruin the paint on the truck , so i covered that place with a sticker to hude the rare earth magnet and pervent any damage to the paint job .
    [​IMG]
    in this pic the sticker is shown

    final head shot
    [​IMG]

    5.articulated double blaster - to aim at the enemies better .
    real simple , in the exisiting hole of the double blaster insert a ball joint , drill a female ball joint where the blaster used to connect , now it can move up and down and rotate without causin any paint damage
    [​IMG]
    final
    [​IMG]

    minor stuff like the rubber wheels and the decals are really easy to make if u have any questions or enquiries just ask

    big bot is done


    LIL BOT
    this is more extensive and more articualting :)  part of the project

    1.articulating the arms and hands
    hands are real easy same procedure we did in the big bot -cut the fist /drill and fit the female ball joint /plug the new hand
    here i had to use some putty to make it more secure - super glue is never enough
    [​IMG]

    arms- the lil bot had elbows so there is no need to add any
    [​IMG]
    just remove the screw and shorten the pin in the elbow with your dremel tool using metal( i like carboon ) disc.

    now fit a ball joint (female ) in the shoulder with some putty and glue
    [​IMG]
    the ball joint that sits in the shoulder joint has to be long
    [​IMG]
    we will fit that ball joint after all the painting is done cause its irriversible .
    the peg of the ball joint will fit into mp prime short smoke stacks after drilling an hole in the correct position.
    i secured the stacks with a plastic washer and a screw .
    [​IMG]
    [​IMG]

    i covered the peg with some spring to make it look more robotic .

    giving the arms some turn
    cut the arms with a saw or your dremel tool- if using a dremel dont cut on high speed and make stops every 2 -3 sec-the heat will melt the plastic and u'll cut more then u need .
    i used a connection from lego technic to make the turning arm
    [​IMG]
    secure the female part( damn so many females -lol ) with putty and only then secure the male one .
    [​IMG]
    [​IMG]

    2. legs
    lil bot has articulation in he psudo knee, that wasnt enough for me so
    disconnect the legs from all the screws - remove all the wheels
    in the back side of the legs they are connected with an H shaped plastic piece - disconnet the legs by cutting the plastc the connects them with your dremel tool .
    the feet holds the connector to the trailer -dont loose that part!! its on a rod , cut the rods an fit them in their original place without the trailer connector piece .

    knees - the green joint that was supposed to fit the arm , will b used to make a double knee joint .
    [​IMG]
    the hollow space of the hip will fit the joint after some sanding .
    cut the knee like this
    [​IMG]
    fit the joint in place and u can apply small amount of super glue , when u are satisfied glue it with epoxy glue and putty it .


    hips
    sorry but no pics here at all

    i used a classic mirage( dragstip KO ) hip to replace op's
    the hips are again with ball joints ,i cut the red connector that the hips are originaly attached to and welded it together with the new hip .
    i reduced the outer edge of the hip to make him more movable - the boxy shape didnt allow much !
    and when attached him back i used a thick washer to push the red connector abit further away from the front position they were before and made them more middled.

    now your bot will look like this
    [​IMG]

    head
    that was a tricky patt but i like how it turned
    to make the head (which os hollow ) fit inside the tiny space i have to use a double joint - a joint that will allow movemnt not only on Y axis but also on X axis .
    i used a ball joint the was connected to a swivel joint from the real gear camra guy ,
    its the smae joint as here in the arms - it can swivel and has a built in ball joint on the top.
    so a female ball joint inside op's head
    [​IMG]
    i had to make a rectagular groove in the plastic with a hand held chizel tool with a 90 deg V SHAPE to fit the rectagular rnd of the new joint
    [​IMG]
    [​IMG]
    like a glove !!!

    thats all folks .....
    for the build


    i'm here to answer and guide u through this

    hope it helped abit

    the final pics of this used tobe " brick bot" are here

    This isn't a knock on bellyboy (Great tutorial), just an observation..

    Hasbro really screwed up with the PMP mold. That thing is a brick. Even with this added articulation, the thing is way too thick. I'll never forget when I was a kid I thought the whole concept was sooo cool, and my parents actually bought me one, and then I remember being totally disappointed at how little articulation it had.

    On the other hand, the normal prime, was a lot more slimline than his G1 component, so I played with him more than I ever did PMP.

    Bellyboy, how did you split the head like that? Did you just use an exacto down the seam? Oh, and a suggestion... You should come up with a way to fix his arms in place while in robot mode so they don't fold forward like that. I'm sure it adds reach and it's an extra articulation point, but it looks very unnatural on the bot. And a piece of heat shrink tubing would cover that spring in his neck and still function. Not sure if you can find it in color though.

    If you guys have any questions about the process (not comments), now would be the time to ask bellyboy.

    Thanks to bellyboy for all of his hard work on this :thumb
