[meteorite-list] Taking a look inside a chondrite meteorite

[Jim Wooddell]

Hi Count!
I have used the Dremel from the truck for a few years and it sure has
come in handy.
I have an inverter mounted in my truck that easily handles the Dremel
and it also handles a coffee pot where I can make coffee or heat up
water or whatever.  The inverter is a solid investment in mobility.
I have a green wheel on a Darex grinder at home and with the cost of
savings (comparing to a diamond wheel, it does chondrites very good
and you just have to square it up now and then.  I can buty several of
these for the price of one diamond wheel.  I do have a horizontal
Diamond lap but seldom ever use it.  I normally end up finishing with
wet/dry sand paper to about 1000 grit (in steps of course).  I find it
soothing doing this by hand.
All toys are fun though, eh?

Mine bench grinder does have side guards that would have to be unscrewed and dismounted. Now I have a four station wet/dry cabachon maker that has a six inch flat polishing wheel on one side that you can stick different diamond grit discs on. I like it because there's no mandrel in the middle and it's easy to change the discs.
