+===== Grizzly 20" Planer =====
+** Champion: Rick Pretsch **
+Good evening all,
+Your woodshop champions and trainers have thought a lot about how best to make Norwich a premier woodworking facility.  After evaluating numerous options, the decision was made to buy a new planer for Norwich.  Previously, we had discussed buying and refurbishing an older machine.  The cost in time and money to pursue this path did not provide any great advantage.  With all of the other projects we are faced with, the decision was made to buy the Grizzly 20" planer listed below.
+https://www.grizzly.com/products/grizzly-20-5-hp-helical-cutterhead-planer/g1033x
+The approximate cost will be $3,100.  The woodshop fund is currently at $0.00 and we have a lot of expenses looming in the next few months.  Any donations large or small are greatly appreciated.
+A high quality planer will go a long way in giving us the capability we want and need.
+Thanks in advance for your support.

+=====  CNC Router =====
+**Champion: Markus S.**
+The machine has had its control cabinet stolen so It is essentially only the mechanics of the machine. This means it will need new motors or servo drives and a controller etc.
+About the machine:
+It is a Thermwood 5-axis 5 foot by 10 foot CNC router.
+And is built solid like very few other machines. It is a fixed gantry style. Meaning the table moves in one direction. Which makes it even more rugged and makes maintenance and installing motors etc easy. The main downside is that it makes for a very large machine. During operation, it will need 8.5 feet by 20 feet of space. It has about 3 foot of Z travel so it can make pretty tall things as well. It is rigid enough that machining aluminum will be possible.

+The Plan:
+Buy the cnc router along with a second that is part of the deal for $2000.
+Harrison will move it for us to Norwhich. He will be looking at the machines later this week and give us a firm quote. For now his best guess was 1000 but let's plan for $2000.
+Then I will install Teknic clearpath servo motors. They are much easier to use and tune than other servo motors. The controller is integrated with the motor, and they get hooked up to power and get controlled with step and direction like a stepper motor. Just with a lot more precision, speed and power. These are the same type of servo motor that I recently installed in Tom Gondek"s CNC router.
+We would use uccnc as the software platform. It is much better than mach3 but still very easy to use. The controller and break out board can also run mach3 and mach4 if we wanted to.
+Initially I would only install 3 axis operation and lock down the 4th and 5th axis. When we want to buy the extra two motors we can then use all 5 axis.
+With the 3 feet of z travel we can also set it up with a wood turning lathe to operate as a cnc lathe for wood turning.
+The machine already comes with two vfds and a 7hp German made spindle motor. (costs about 3-5 grand new)
+The total cost of the project would be $7570, maybe less depending on Harrison. Keep in mind that these machines cost more than $100 000 dollars new.
+To add the 4th and 5th axis and other optional items later on it will cost an additional $3000-$4000
+In addition, we would be getting a second 5 axis cnc router that is very similar but has two 5 foot by 5 foot tables. It can be taken apart for parts or turned in to a second working machine etc.
