Ouch! They've been reasonable for the stuff I've been looking for
recently, so I thought they might be worth a look. That quote would
have given me sticker shock too.

I think, for those of you using this stuff to make a living, that its
probably a persuable idea, if the delivery times were like overnight so
you could get back to work.
Being retired, and the senior member of this list, my time limit is when
I run out of time & forget to wake up in the morning. :) If it takes me
2 or 3 hours a day for a week or more to make the pulley's for this, it
is not that big a deal. ATM I have 2 or 3 other projects not related to
this, like cut some edge fillets out of a plastic sump pit, which is
easier that chisling the cement away precisely with a 57lb electric
jackhammer so the sump sits solidly on its flange, then I can mix up
enough cement to refill one edge of the hole, I had to move it away from
an outside wall of my basement when I ran into the house foundation
about 5" down, so I had to move the hole about 6 or 7". Get that done,
and some permanent 1.25" line up to a extra deep P trap just beyond the
tub/showers trap and deliver the water to the far end of the house where
it will enter at the head end of the system, thereby helping to keep it
This place was built in '74, by a contractor that couldn't pass the
plumbers test if we gave him the answers. There are, I'm sure you've
heard, just 3 answers, shit runs downhill (fail), hots on the left
(passed) and payday is on Friday.
Then I went over to Lowes yesterday and bought all the 8' treated 2x6's
they had that were good enough for deck planking, and started ripping
out the 2x4's I put down in 2003 or so when I put a front deck on my
shop building, but figured CWF would be good to make it keep. Silly me.
The neighbors across the back fence have something that looks sorta like
a maple that shades the shop somewhat, but it sheds so much junk it
keeps a soggy mass of litter that would need cleaned up and burnt about
weekly, which of course hasn't been done. Net result is that I have put
a foot thru it in 2 places now & feel like it could be quite a few more
if I don't walk my 170lbs around carefully.
So I brought the last 5 gollon bucket of clay from the pit up this
morning, then threw a 60lb bag of sackrete on the riders hood & drove it
around to the back porch, put it back on the 2 wheeler and took it to
the basement and brought the sump up so I can trim that plastic away
outside, keeping the stink away from the Mrs & her COPD.
That about wore my back out so I spent the rest of the afternoon working
on the first pulley, fighting with the lathes computer as its uptimes
recently have been hours, crashed 3 times on me while doing that. It
will be made from 2 pieces of 1/2" fairly hard alu, lapped a while on
600 grit on a granite surface plate, then wet with superglue and clamped
overnight. One piece is held in my 4 jaw, and the other piece was
turned until it was clean & about 71mm in diameter, then tried to bore a
taper-lock hole all the way thru it at the usual 3/4" a foot taper. I
think its big enough, but will re-measure and increase the diameter if
needed to get about 1mm of steel minimum between the alu and a 20mm
shaft. Once thats done, make the hub out of old mine shafting and slit
it at 90 degrees, then drill & tap the 6 holes for some 6-32 screws.
Make a 20mm shaft to put it on for the rest of the rib machining. So
1/2" of it will have a pitch diameter of about 67mm, and the other half
inch will be turned down to around 42mm, and ribbed for about a 38mm
pitch diameter. Using a 3 rib belt I think. The 2nd pulley assembly will
be just like it, except the taperlock will fit the 8mm shaft on this 400
watt motor I took out of the lathe. If I can arrange it, the faces of
the two pulleys won't clear each other more than 5 or 10 thou, putting
the motor much closer to where I want it.
With 2 pulleys like that I'll have a stepdown, or a stepup in spindle
revs, depending on which pulleys the belt is positioned at. The up is
sorely needed when doing a pcb etch mechanically. Or carving the fingers
on more of the Green & Green style furniture. I obviously do a lot of
this by the seat of my pants. :)
So I have plenty to keep me as busy as I want to be at what is now 80 yo.
And its next to find a psu for that computer, its an ARK shoebox, with a
D525MW mobo in it and some sort of a psu that looks like a lappy's psu
without the candy bar outer box. IIRC. Need to look again. Tomorrow
if its not raining. That pretty girl on tv says its likely.
Now that I have bored everone out of their skulls, I'll get me coat & say
goodnight all. ;-)
