Just a brief rundown of my days (or few days) activities.
I thought some would like so see some of the work behind making a new pirk.
very much a storyboard in pictures but here you go, I will eventually get a more detailed account up on my website but for the time being I hope this may be of interest.
I start on the design side and in this particular case (a speed pirk) it is a solid made from a number of cross sections starting with basic circles of various diameters on differing Y axis. After applying the solid it is then scaled in a non linear direction (ie turns the circles to upright ovals) which gives more of a shape (and add the eye socket as well at this point
Then, since this is going to be used for a mould I require only one half so it is cut in half .... next step after sitting this (in software not in real) into a block and adding geometry to make the pouring spru is to add tool paths for tools to follow to make machining of the mould possible
Next, again still in software not in reality is to verify the tool paths actually cut what you want to see ... and if all is well ... put a block of aluminium on the machine
Then ... begin machining ......
Ending up (hopefully with the parts as designed all ready to start casting ..... like this
The final Result ........
Hope this is of some interest

brilliant norman!!!!!!!!!!!!!!!!
Light travels faster than sound. This is why some people appear bright until you hear them speak.
