Re: robo3687's Iron Man 2 Pep Files - neck seal!

When it comes to hardening the helmet, at which point would you cut out the faceplate?
If i wait til after the body filler i wont be able to see the lines for the faceplate. Also, i have been using fiberglass tissue for hardening the inside, but when the resin dries, the fiberglass still feels grainy and rough. Any tips please, fiberglassers?

My helmet is on page 19 / post #451

I never connected the 3 pieces. I used small binder clips to hold them together. (1) Resined the outside (careful not to bond the pieces together with resin). (2) Then fiberglassesed the inside as much as I could. (3) Removed the binder clips (and seperated the pieces). finished resining and fiberglassing the parts I couldn't reach when it was together.

If you don't like the feel of the inside and you don't think the padding will be enough to cover the rough feel of the fiberglass then you can dremel down the bad parts and add a coat of resin to the inside, on top of the fiberglass, to help smooth it out.

Re: robo3687's Iron Man 2 Pep Files - neck seal!

i dont mind at all, i was just making sure this is how its meant to feel. i was expecting it to be smoother, not rough as a badgers arse (from what im told badgers arses are rough, i didnt personally check... :-/). So this is correct then? fiberglass tissue meant to have a grainy/rough feel to it once finished?

Off to page 19 for a look

EDIT.... were actually using your helmet as reference now...

Nice work MightyJohn, you're helmet looks awesome! Thanks for the binder clips tip to hold the pieces together during the resin and fiberglass process.

Re: robo3687's Iron Man 2 Pep Files - neck seal!

To avoid starting a new thread, ill just piggyback this one. finally, after 2 months of starting the cutting and gluing with 2 failed scaling attempts and one tester, i have finally finished pepping sharkhead's IM helmet. This is my first pep (if you dont count the failed attempts). Looking forward to resin and glassing.

All my pieces are glued together, sadly i had already done this before i saw the tip about the binder clips so ill just have to route the faceplate out later.

The last pic is the collection of my summer long work. The first 2 helmets are dung0beetle's file. The first helmet was a tad too small, the second was scaled up 1.5" on all sides which was way too big, the third is the tester for sharkhead's which fit, and the fourth is my final helmet build.

Re: robo3687's Iron Man 2 Pep Files - neck seal!

For those of us building sharkhead's helmet: I have an idea about how to wear it without using hinges. I've been thinking about this for a while, but haven't progressed far enough to actually do it. Since the bottom jaw can be made as a separate piece, why not just attach it to the helmet using magnets, that way you can get in/out without much trouble. Of course, I think you'd also have to have a moving faceplate for this to work properly...

What do you guys think?

Re: robo3687's Iron Man 2 Pep Files - neck seal!

you dont really need a movable faceplate to get in and out with a removable jaw cuz it should give *just* enough room to get in and out of it

 

[td2253]

Re: robo3687's Iron Man 2 Pep Files - neck seal!

That is what I was planning on doing with my helmet's jaw piece; attaching it using neodymium magnets (rare earth magnets) should work just fine. Another option would be tabs with industrial strength velcro. But I prefer the magnet method.

Re: robo3687's Iron Man 2 Pep Files - neck seal!

personally i have been studying how the helmet opens and closes, and when its in the open position, the jaw is slightly ajar. i think one could put a medium strength small spring horizontally connecting the helmet and jaw piece on each side so one could just extend the jaw and put the helmet on. for the ajar effect, one could rig a pulley system on the inside of each side of the helm and have the springs tighten when the faceplate closes and slightly loosen when the faceplate is raised.

the best bet for an operating faceplate that i've seen is modified tacklebox hinges.

Re: robo3687's Iron Man 2 Pep Files - neck seal!

Hey guys, talking about the helmet, i made one at the default scale and it was too big so i made one at the 95% scale, the measure given from pepakura is right the fisical one and the helmet fits me well wide but if i turn in the mirror i realice that is way too long and it makes it look`s bigger.

Wide is a lil tied, so i can`t reduce the scale more because it will not fit me, could i rescale the patterns changing just the depth? would it look bad or lose shape i wold like to know what you guys think? anyone have the same problem?

Some pics of the helmet peped and one from me on the mirror (sorry, just one for now)

Re: robo3687's Iron Man 2 Pep Files - neck seal!

got my chest pep'd here and calling it a night - took 8 hours just for that one piece and it looks like its going to take a day or two for the back

yes it is backed with cardboard

any one think i can seal this thing with enamel? i still intend on using fiber glass on the inside and goingright to bondo on the out side, also planning a pair of LED fans where the vents are so i did not pep those in

also planning on glassing the chest and back as one peice - any one do that? if so how did it turn out?

 

[robo3687]

Re: robo3687's Iron Man 2 Pep Files - neck seal!

the back and chest actually only meet up in one place....on the sides....

they don't directly join at the top as the collar plate bridges the gap...

so if you want to resin it all as one piece be sure to include the collar plates....

 

[brimst0ne13]

Re: robo3687's Iron Man 2 Pep Files - neck seal!

i'd glass all separately just to keep it from warping.

Re: robo3687's Iron Man 2 Pep Files - neck seal!

i am almost finished with the chest pep , as soon as i am finished i will glass everything i have done till now!

Re: robo3687's Iron Man 2 Pep Files - neck seal!

Thanks guys ^_^

@ robo - i just finnished (right this moment - started working at 8 PM last night and went al the way to 6AM) on the back and checked it against the chest and found that out lol. im guessing that it goes right up to the brace?

im going to glass later tonight and take pics after i bondo - after wards i think im going to continue down then the arms

Re: robo3687's Iron Man 2 Pep Files - neck seal!

Ok SO I see a lot of peep's are working on one piece, pep, glass, bondo then move on to another, then another.

Maybe I am being over cautious but isn't this going to increase the likelihood of hitting scaling issues, particularly where things need to join together such as knees and elbows etc ?

I am aiming to complete all the pep parts first and ensure a good overall fit. I started pepping at the feet and am working upwards (saving the helmet till last so I will have had lots of practice) then once everything fits I'll start the resin/glass/filler process.

I was also thinking would it be best to be planning how the bits are all going to be mounted onto the wearer at this stage too so any attachment points can be included in the glassing stage ?

I have seen a few costumes using webbing straps and buckles but I am worried that they are gonna force some of the pieces too close to the body, the shoulder bells seem to be particularly suffer from this.

I was thinking some kind of exoskeletal framework to attach the pieces to might work best (a bit like how you see it in the movie but not as complex!) Any thoughts ? Am I worrying too much ?

Re: robo3687's Iron Man 2 Pep Files - neck seal!

Just come back from a very frustrating fiberglassing session. nearly finished fiberglassing the chest piece. Have decided fiberglassing is way to stressful. Can any one advise for or against skipping fiberglassing for the rest of the pieces? I wish to reinforce with ressin inside and out side instead. I dont wana cut corners and if theis is extremely undavisable please let me know ASAP.

Re: robo3687's Iron Man 2 Pep Files - neck seal!

I brush resin on the outside and then slush cast Smooth On Smooth Cast 300. Works like a charm. Is non toxic and you can use it indoors. Great stuff. It is how I hardened my helmet.. you can also build up any desired thickness with it.

Re: robo3687's Iron Man 2 Pep Files - neck seal!

In my opinion, the problem with having a dozen paper pieces is that you run into the chance of the pep deforming, getting crushed, etc. Plus it drives you insane to sit there cutting, folding, and glueing for weeks upon weeks. I say pep a piece, check to make sure it fits, resin it and move on. You should save finishing for last to make sure everything comes out even.

You should plan how you are going to attach your hardware like bolts and such but i wouldnt install anything until you get to the filler stage. With some low profile bolt heads or rivets, bondo should cover those up and so it can still be sanded smooth.

Your exoskeleton is a clever idea but id be worried about the limits of your mobility. Remember that the more complicated you make something the greater chance you will run into problems. The skeleton could add too much weight, or restrict your movement, or add too much bulk to the armor. I've heard of people attaching pieces to other pieces, for example, bells connected to the chest piece instead of your body. If everything is interconnected then you wont need so many contact points with your body. The best medium for spacing the armor away from you is pieces of foam to act as spacers

Re: robo3687's Iron Man 2 Pep Files - neck seal!

Anyone ever slush cast with regular fiberglass resin. It seems like it might be to thick and would take way to long to coat the interior. A friend recommended adding acetone to the resin mix to thin it out but i dont know what the end result would be. Would acetone affect the resins strength, set time, finish, temperature, toxicity, etc?

Re: robo3687's Iron Man 2 Pep Files - neck seal!

You could use Rondo(fiberglass Resin and Bondo) or any body filler for that matter. You slush cast it into whatever part you are making. Here is a video in case you are unfamiliar with it. It is from Ben Streeper on the 405th. He shows you step by step on how to use this product and many others.Hope it helps man.:cool
