These are good machines, I've had one for 4 years now. If you can find a "C" type machine for sale buy it! They are the latest generation and quite well engineered. The previous typs, "A" or "B" tyype can be upgraded to a "C" type by sending it in to the company, LHR, for a very reasonable price. Almost any reasonable price you purchase it for and the upgrade cost will give you a machine that costs less than a new "C" machine.
What to look for.
1) The general condition of the machine, clean, not beat up and all functions operate without problems.
2) Check the base at the serial number. The letter in the beginning represents the type, "A", "B", or "C". "C" is best but not many available used.
3) Low hours on the cut motor. This can be found by viewing the readout screen on the crank side. Ask the owner to show it to you.
4) The shipping box with Styrofoam in tact. Important because you'll need it for any shipping or transportation.
5) The sandpaper X drive belts are not wrinkled on the edges from creaping to the side.
6) Check the chuck that holds the cutting tool for ease of operation, bits are removeable easially. A tool is included for this if it's needed. Perhaps the past owner has upgraded the chuck, this is a real plus!
7) If a scanning probe is included be prepaired to pay for the lisence. Contact Lynn at CarveWright to do this.
8) Be aware that you'll need a receipt to transfer ownership from the registered owner to you. Contact Lynn at CarveWright to do this. I believe that a stolen machine will not be allowed to be transferred!
9) Items included in the orgionial purchas are included in the offer. Memory card with programer, 1/16" carving bit, 1/8" cutting bit, bit ejection tool, check with CW for other.
Some other items should be looked at or be aware of, obvious as with any used machine. PM me if you'd like more info.
By the way, I have a machine with only 10 hours for sale along with an 11 piece bit set for sale. Need money for Christmas. All listed items above are good.
