My first attempt at segmented blanks ended up as sawdust on Friday. Made the mistake (among MANY others, but this was the fatal one) of using bog oak for contrast. Man, that stuff is SLIMY! The beech I segmented it with went sort of muddy while I was sanding ...
Bog Oak ugh ... I hate the stuff, i remember when i first turned a piece of this wood, my thoughts were what a waste of good cash, i still have a couple of pen blanks, but i doubt i would use them. Certainly not good wood to use for segmenting David ...
The idea is to fit a cast iron slider that sits above the table by a few mm's with a fixed mite on it. He made the alterations at his home, so when he brought the runners fitted to the slider it would only run for about 2" 
So i ended up taking the table off the bandsaw altogether so he could take it home and make the alterations at his place. So i then began to make a back fence for a mitre saw that i just purchased so that i could cut at 45 degree angles with small pieces of wood (pen blanks) I got the wood screwed into place which was awkward as one hole was blind ... When i got this done i had nothing to cut the shape .. Other than this i have four blanks in the pressure pot, hopefully all will be well on this mix ..All in all it feels as thou i have achieved
nothing this week ...
