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. image.png 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.
We acquired a 20” Rockwell bandsaw for $500. We are asking members to toss in a few extra bucks to the wood shop fund to defray the cost. Our goal is to raise $250 toward this purchase.
This saw will be equipped with a wide blade capable of handling larger wood pieces. The idea is to have this saw setup for making straight cuts on larger pieces of material while the current band saw will be outfitted with a narrower blade for making radius cuts. Both machines will have appropriate limitations posted on the front cover. The current bandsaw breaks blades quite often because users are trying to cut large pieces on a narrow blade or radius cuts on a wide blade, both cases overstressing the blade. Our hope is having two machines to fit both needs will meet everyone's needs.

Lets make stuff from plastic, add your pledge below…. We can make molds using the Tormach!!!
This is on an auction site no guarantees here. Note: I'v kept the naming of the machine vague here so outside prospective bidders don't stumble across it while researching it. Please do not post the make, model, or location of the machine until the auction concludes Dec 19 in the evening.

It was determined that a fire had started in a bank of battery chargers. The fire spread to the entire stand of batteries and chargers. One school employee was taken to the hospital due to smoke inhalation suffered while using a fire extinguisher. The fire was contained to the robotics laboratory. Damage is estimated at $45,000 to $50,000. Fox6 article
Let's see if we can help get the school's Robotics Lab up and running again.
Total: $125 - DELIVERED!

The South Bend lathe would be much more useful if it had a digital read out, a digital readout(DRO) measures the actual movement of the axis and then displays the information on a screen. The Bridgeport mill along with the Gorton mill already have DROs. Using DROs account for backlash and generally make it easier for beginners and advanced users to make accurate parts.
We are purchasing a Tormach 770 Vertical Milling Center with automatic tool changer. It is currently being used as a demo machine in their lobby. Until we pick it up we're unsure what options will be included.
