Features: 1. Motor case and headstock are jointed. Maximum motor power is 144W by using more powerful motor. Some parts are electroplated to make the machine more beautiful and practical. The parts in the kit can be assembled into 10 kinds of machines with different functions: bow-arm jigsaw, wood-turning lathe, metal lathe, beads machines, milling machine, drilling machine, sanding machine, hand-held machine, dividing machine, big wood-turning machine, only one kind of machine can be assembled each time. 2.Main parts: headstock, central block, jigsaw base, jigsaw casing, motor blade, gear, woodturning chisel base, cross slider, big slider, drilling lever, drilling table, jigsaw table, connection piece, tailstock, sanding paper panel, dividing positioner, vice(all of the parts above are made of metal), drive belt cover, grinding wheel, wheel guard. Technical parameters: 1. Motor speed: 12,000rpm/min (optional choice 20,000rpm/min) 2. Input voltage/current/power: 12VDC/5A/60W, switching power input: 110V-240V 3. Jigsaw working table size: 90mm*90mm 4. Maximum working material diameter of metal lathe and woodturning lathe: 50mm 5. Working material length of metal lathe and woodturning lathe: 135mm 6. Center height of metal lathe: 75mm 7. Slider travel: axis X 145, axis Y 32, axis Z 32 8. Collets: 1-6mm 9. Drilling working table size: 123*100mm 10. Maximum work piece size clamped by vice: 50mm 11. Maximum work piece diameter clamped by three-jaw chuck: 50mm 12. Maximum beads diameter: 20mm 13. Maximum work piece diameter by big wood turning machine: 130mm 14. Work piece length by metal lathe and wood-turning machine: 280mm 15. All machines are safe to touch except milling machines. It requests to use under parents or teachers instruction when the milling machine is being used by the kids. Thickness of working material of jigsaw: hardwood 4mm, plywood 7mm, soft wood 18mm, aluminum 0.5mm, acrylic 2mm. It is a good tool for families and schools to do model airplane and other wood model crafts. 16. The outer package, called as storage box, is made of plastic, not foam. Inside of the storage box, there are 3 transparent food-grade plastic box containing machine parts and other 2 transparent food-grade plastic box containing screws. With the good package, it is much easier for the students to store the machine parts and it also increases the machines service life. (Remark: to put the certain parts in a certain place, we designed 6 locating slots in the storage box and each locating slots is completely covered by the locating block. Therefore, the machine parts will be well packed and easily taken out.)
