Hi,
newbie here, so sorry for some of the silly questions I'm about to ask (I'm more of a plastics and metal guy).
Are you using glued sheets of MDF for the material you're cutting?
I assume this is a computerised mill to take in your 3d image. How much would a mill like this cost?
What kind of polyurethane did you use to seal it if you dont mind ?
Its called UDF (ultra dense foam) the brand I used is signfoam. Its a tooling board used in the sign industry. I glued them together and once the cnc code is generated from the tool pathing software its just a matter of sit and wait and watch. I built my first mill from scratch for about $3000. There are some decent starter kits out there and some good hobby machines. But industrial machines get into the $100,000 range. I wont tell you how much I paid for this setup, but feel free to contact K2CNC and get a quote if your interested in gettng into the cnc world.
Once I had the shape I wanted I used poly urethane to seal up the foam. Then.... sand ... sand.. sand.. and sand some more.. Still needs some bondo and touch-ups.. but its coming along nicely.
I don't know what is more incredible... the sculpt (well, it isn't exactly a sculpt... what do you call it?) or the extremely short amount of time in which it took you to produce it!
Man, that is absolutely beautiful.
But one question. I might have missed it if you mentioned it earlier, but why are you sculpting it with the visor part? Not planning on adding plastic or are you going to cut that off after the mold is done?
Can you take a photo of the backside of the helmet sculpt? I am curious about the beveled lines back there.
