Over the last few weeks ive been getting my hands dirty with this sculpt, havent used clay since Highscool (20years) so there have been plenty of flashbacks to the highschool art class as I have fumbled along.

Here are some screens shots of the helmet I took on my phone, some of them show off the profiles of the helmet.




I found this shot interesting as it looks like they used a silver Rub&Buff type product instead of paint or ColdCast as the R&B has transfered onto the chinstrap. (Where the strap meets the helemt)


Good shot showing the spike pattern




Some pics of the sculpt so far..












I have a supply of Smoothon to make a mold once the sculp is finished

Thinking of calling it The ButtHead Head Butting Helmet (TBHHBH for short lol)

Re: BTTF2 Griff Tannen Helmet and Slugger 2000 builds

Bat is being made from Alloy and will function the same as is did in the movie (Fingers crossed)

Here it is after cutting the pieces to the approx size

The basis of the spring mechinism. Lots of beer and braincells were destroyed coming up with this concept.

in the Open position

Closed - When the bat is closed the spring is under tension and will be held in place by a yet to be designed 'lock/switch'

After turning up the alloy pieces it starts to take shape

turned up the sleeves for all the pieces so now it slides nice and smooth. I'm hoping that the tolerance between the parts will prevent air from flooding into the bat as is springs open, this should help it act just like compressed cylinder as it does in the film.

Oh! Thanks guys I edited that post with photobucket links, pics should be showing now.

Also finished the spikes for the helmet on the weekend, When I say finished I mean I'm finally happy with the angles and linage, now to patch, repair and smooth over.

can I ask you what you used for the alloy of the outer part of the bat? I can't find anything to use that I like and yours looks perfect!

This looks awesome! The spring mechanism is very impressive! What are the measurements of each segment of the bat?

Re: BTTF2 Griff Tannen Helmet and Slugger 2000 builds

I used Aluminium Tubing from a metal supplier and just cleaned up the surfaces on the lathe at work. I've been told my measurements are over 95% accurate to the dimensions of the screen used stunt bat.

The measurements took me a long time to do from scaling and researching bats online and from watching the films and screenshots. At this point in time I don't want to give away my hard work, especially while the project is still in the early phase, also I may consider doing a small run of bats.

So for now, sorry guys but maybe I'll release some diagrams and measurements in the future.

in the mean time here are some more sculpt pics!

Very close now, looking forward to molding this sucker soon.

Re: BTTF2 Griff Tannen Helmet and Slugger 2000 builds

Pre-casting process starts this weekend. Also done some more cleaning and smoothing since these pics were taken.

I'll be using Smooth-on 30 for the casting process and was wondering if anyone could suggest a molding method?

Would this shape require a split mold or could I get away with more of a Silicon sleeve method supported by a removable hard outer shell?

This won't be the final mold as I feel I've done all I can for now with this clay i'm using. It's just become too hard to work with even after using a finer grade clay. I'm happy with the basic shape, I just need a few copies down in resin so I can finish it with methods I'm more familiar with. Sandpaper, filler and putties please!! this clay is killing me

Thanks for looking!

Re: BTTF2 Griff Tannen Helmet and Slugger 2000 builds

So, using the brush on method I applied three coats of Silicon

Then created a two piece support shell using plaster bandage

The Resin I used is Smoothcast 300, I love this stuff as its easy to use, machine, file, sand, glue and it's strong and light.

Three coats of resin and it's pretty thick and sturdy, the Spikes are solid and the helmet wall thickness is about 4 - 5mm thick.

Just out of the Mold!

Trimmed up

Might not look as pretty next time! Now to get out the Plastibond and fillers and keep working on the shape.

Really been enjoying this project, It's been a fun learning experience.

Thanks guys, hopefully you like the finished Prototype

But first a few more Progress pics!


Lots of putty, was used to finalize the shape, although it doesnt look it there would be about 2 toothpaste tube sized packs of putty was used.

So I used Tube putty (MilliPutty) two cans of spray putty and two cans of surface primer.

And now for the final reveal! (Still need to make a chinstrap)

Thanks for looking!

Looks great! Good job!
Is that straight rattle can silver or did you use a rub-n-buff on it?
