JohnBrewer Posted March 21, 2018 Share Posted March 21, 2018 Following @thelivingdead531‘s post here I wanted to have a go. Firstly I didn’t have any gem bone (hint hint - I’ll be putting a wanted post in the relevant forum in a bit) so just regular dino bone. The chunkosaurus I use is water tumbled and found on The Isle of Wight, UK. Could well be iguanodon. Any chunkosaurus will do but it needs to be hard and mineralised. You need something to cut slices. I used a £40 electric tile saw. Be careful! I found a generous amount of hot glue on the bone and a piece of brick as it has a flat base making even slices of the fossiled bone rather than my finger bones. Slices done, they now need grinding. Tedious using wet/dry silicon oxide paper by hand so I spent £10 on a big auction site to make a Frankenmachine. A PC power supply and 3 old hard drives. Dismantle the hard drive(s) - I bought 3 - ditch everything on the top bar the platter (the silver round thing). Actually keep the rare earth magnets they’re rather fun to play with. You’ll need to take the platter off to remove the bits not needed. No make a circle of silicon oxide using the platter as a template. I was thinking that to attach the sanding disc to the platter I’d need glue of some type but I didn’t. The platter retaining ring clamps the sanding disc well. 2 John Map of UK fossil sites Link to comment Share on other sites More sharing options...
JohnBrewer Posted March 21, 2018 Author Share Posted March 21, 2018 Of course you’ll need a computer PSU (power supply unit). Some of the early cheap ones don’t have an on/off switch on the back, mine didn’t. no big deal. On the wiring look you’ll find the main board connector. This is easy to find, it’s the largest connector. Cut the green and any of the black cables and spline together. your PSU will now kick in when plugged in.

JohnBrewer Posted March 21, 2018 Author Share Posted March 21, 2018 Plug your hard drive sander in and check it works. yep, that works and it’s spinning, depending on how old the drive is from 5000 to 7000 rpm. Try grinding by hand at that speed! 2 John Map of UK fossil sites Link to comment Share on other sites More sharing options...
JohnBrewer Posted March 21, 2018 Author Share Posted March 21, 2018 So I then got a slice of bone and tried holding it on the disc. Sorta works but I didn’t have a great deal of control and a couple of times it flew out of my hands st 5000rpm. 1 John Map of UK fossil sites Link to comment Share on other sites More sharing options...
JohnBrewer Posted March 21, 2018 Author Share Posted March 21, 2018 Hot glue and a screwdriver gave much more control. John Map of UK fossil sites Link to comment Share on other sites More sharing options...

Miocene_Mason Posted March 21, 2018 Share Posted March 21, 2018 Now that’s some ingenuity!

JohnBrewer Posted March 21, 2018 Author Share Posted March 21, 2018 All of these cabs are work in progress, only 150 grit has been used. I think I’ll go with 150 for shaping and first grind gradually getting finer and finer and finishing using my three hard drives for the final grinding prior to using rouge on my Dremel.

jpc Posted March 21, 2018 Share Posted March 21, 2018 cool. How do you undue the hot glue? Do you just heat it up and scrape? Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted March 21, 2018 Share Posted March 21, 2018 I didn't understand a word of it. But I'm sure it's very clever and the results speak for themselves. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

It’s fairly easy just to unpeel but a hairdryer or or heat gun gently works well. John Map of UK fossil sites Link to comment Share on other sites More sharing options...

Ptychodus04 Posted March 28, 2018 Share Posted March 28, 2018 @JohnBrewer are you grinding your chunkosaurus dry? If not, how are you handling excess water?
