The motors, this low RPM (5-8) are hard to find actually.

DC motor with a pwm controller should get you in the range.
With variable speed you could experiment with a variety of
different meats, poultry, fish, and veggies. Bodine dc gearhead
motors used to be fairly cheap on ebay. CNC cooker ?

Yes, and no, because you lose on the power. I am glad that Steve B
finds so many low RPM gearmotors. I never found any. I can buy one
from Steve if he wants to part with one. I need 5-15 RPM.

I can make my own custom sprockets now with CNC.

Yes, but unless they are particularly large, it's cheaper and easier to
just buy them, Tractor Supply and similar have common ones retail cheap,
and Surpluscenter and similar have full lines cheap for the ordering.

I already looked in surpluscenter and did not find any.

5-10 RPM gearmotors are VERY rare.

i

I was referring to sprockets.

Surpluscenter periodically has low RPM gear motors, their availability
varies.

I can make sprockets very easily now.

Not as easily as you think. Take a look at commercial sprockets and note
the profile of the teeth, they are not simple flat plate pieces, there
is an edge taper on both sides to allow the teeth to engage into the
chain without catching. If the teeth are flat, the chain is centered on
the sprocket, and the next chain link comes along and there is no
clearance into the chain opening and it can catch if the chain isn't
perfectly straight. The taper on the tooth allows it to fit into a non
perfectly centered chain and guide it into proper position. I believe
most of the commercial sprockets also have some heat treating to make
them more durable.

Is it worth the effort to spend a couple hours plus raw materials to
make a sprocket that you can readily buy for $5-$10? Unless the sprocket
is large, it's just not worth it.

At 5 rpm, and with the ability to make as needed, heat treating would be
overkill. Yeah, they would last longer, but just how long do they have to
last when you use it 4-8 hours a month?

Yes, but you can buy the sprocket for $10 *with* heat treated teeth,
hub, etc. ready to go. On Surpluscenter.com, #35 sprockets start at $2
for the small sizes and go up to a whopping $22 for a nearly 9" dia
sprocket, still with heat treated teeth and hub ready to go.

If you need to cut a 4' diameter, segmented #100 pitch sprocket for some
giant turntable, it probably makes sense to DIY it, but not for ordinary
off the shelf sprockets.

Keep going. Your enthusiasm had me trying to get a live cd working on another box so I
could poke at things a bit until I can come up with a machine to convert. I was trying to
run from the cd and use the -- persistent option but it never wanted to use my casper-rw
file on C: that should have stored any changes I made while playing around.

PC has USB 1.x so running from usb using www.pendrivelinux.com is a no-go.

My triple boot box that has linuxcnc installed is tied up most of the time running winapps
so I was trying to get an older box to work.

The next upgrade to Alibre will likely have me buying a Win7 box and then I can put my box
with the linuxcnc install back in service.

I am really enjoying your posts on this project.

If that. I agree with you. Who gives a fsck about heat treating. If it
wears out, I will just reuse the same G code as I used to make it. But
it will not, of course, wear out.

When I worked in the oilfield, casing was used to make barbecues. O rings
from flanges were used to build boilers, and there were thousands throughout
southern Louisiana and Texas that were paid for by the oil companies. Don't
know how much those rings cost, but everyone had at least one. Simple
piping with a cap on the end with a small hole drilled, then a countersink
to vee it out. Then just a little wind protection collar that mixed the
outcoming gas with air. A twist variable $20 regulator to the tank. Nice
boilers.

A piece of 20" casing about six feet long made for a heavy barbecue, that
could be properly used as a barbecue with the fire at one end, and the meat
at the other. I had one I made, and helped load many a pup of 20" casing on
a truck or into a trunk.

Damn, I wonder what it would cost for a Sch 40 6' piece of that pipe in
today's dollars. And that didn't include the legs, expanded metal, or any
of the fancy side tables, or 3/8" end plates. Heavy when completed.

I figured it was spendy, but my, it made a heat retentive slow cooker. The
clear coat on the outside was something else, too, and lasted forever.

Now that I've got the shop going, I see a cooker on the event horizon.

Always starting stuff, ain't ye, Iggy?

Probably not the gear motor you have said was spendy, but just the light
kind off a backyard rotisserie. With proper support, and minimal
resistance, should do smaller amounts of meat. Going to buy the next
rotisserie I see and build a small one. But it will be enclosed, not open
like the one Ig posted.
