I'm thinking about buying one of Dirty Donny's paint it yourself Shrunken Head kits..... once it's painted I want to drill it out and tap it or some how make it in to a Shifter Knob from my car. I email Donny and he said that it's made from ( poly-stone resin ). He has never tried to drill it but he feel that there is a chance that it might crack and break. I was thinking that I might be able to do it if I start with a smaller drill bit and work up from that. I think the poly-stone resin is very similar to that of a pool ball.... I have had friend in the past that have drilled them out with success. I'm asking for anyone with information that might have used this type of a product, and if in fact they ever tried to drill it? thoughts? Nader
Thoughts?? I think you should post an intro. http://www.jalopyjournal.com/forum/showthread.php?t=44274 Read rule #6.
Nope, not Ralph I will sign in once I have more time. I hope that I can get an answer anyway....... Nader
Give it a try. Let us know how it goes. I drilled similar material and it did chip. Start very small and work up, it should work brad
Find the manufacturer of Poly Stone,and see what it's made of. Most resins can be drilled,doing it without damaging a delicate design can be tough.
Hey, I just saw this. Poly stone is made in China and very heavy/brittle stuff. I got a resin shifter knob in the works with Gordon from the Vultures. We will hopefully have some this summer.
Most early accessory shift knobs of plastic or glass or stone used a brass or aluminum threaded insert which was glued in place.
Why wouldn't you tap it first? Then paint it... If it get's screwed up drilling you can repair it BEFORE paint. You know, you'd think a CAD operator could figure out how to drill a shift knob!
Life has too many rules these days. All the guy did was ask a question...answer his damn question and then tell him to intro himself. No need to be an asshole!
I've worked with dental plasters and resins. All you need to do is use a drill press with a bit that's 1/3 or less the size of the final hole, keep the bit speed down and go VERY slowly. Increase the size of the bit until you get it to the size of the insert you want to use. Don't try to thread the item, I totally agree on epoxying a threaded insert into the hole.
Another thought. Most plastics are damaged by exposed to sun light, some more then others. I've seen some resin shift knobs deteriorate suprizingly fast. Another thing to look at when you research that resin. If how long it lasts is something you care about, that is.
WOW!!! Look at the FNG teaching the board how to deal with a post. Suppose he has anything to say about us NOT warmly embracing a tuner guy? Frank
Threaded insert is the way to go...BTW, that shrunkin head is kick ass! The guy who sculpted it is a real good friend and seriously talented sculpter...
