Actually it=E2=80=99s just a cheap particle board/formica top on top of =
the cheapest reasonably sturdy cabinets that Home Depot sells. But I =
have granite and marble in stacks and piles outside the shop. It was a =
former granite and marble cutting company. I want to turn it into super =
nice gravel, but my wife envisions some kind of marble project. What it =
really is, is a home for rats. The first time she sees one I=E2=80=99ll =
get my gravel. Until then, does anyone want to buy a marble birdhouse? =
How about a few thousand marble cutting boards.=20

>> Bill, I believe you had a 298D cam that was in an engine from uncle =
jack, but you told me you were not going to run it.  That was a few =
years ago. Someone on the list will probably want it if you don't.  I'll =
send you the cam card.  It should be run with 0 to 4 degrees advance and =
a valve lash of 0.015.

>> Steve Long sent me the specs of all the Erson cams, so the numbers on =
my website should be accurate.  Steve will grind whatever lobe =
separation you want, so you can't use lobe separation to identify his =
cams. The Erson 23 should have similar lift, but a lot more duration =
than my 298D cam.
>>=20
>> Cam timing is confusing because the scales on the degree wheels run =
one way then another. I often subtract when I should add, because of the =
scale direction.  I'd prefer a scale that runs from 0 to 360.  I have a =
couple of Excel spreadsheets you can download from my website that might =
help with some of this.  The one for timing is confusing because of the =
conversions of all the degree wheel readings.
