Myroon ako table drill press Made in China pero yun sinag una, mukhang heavy d and rigid naman. Hardly used ito. Am selling it for P2.5K top.
anyway, to give share some ideas, we can make a drill press for pcb wherein the table is the one adjustable. use a discarded shock absorber from a car. Bore a hole sa ilalim ng SA to release the oil. Careful pag gas type and pressurized. Yung ordinary lang. The shaft can now be freely moved up and down. May nut yung shaft. bolt on a metal plate and align. weld permanently. put a wooden base on top. Sa ilalim,make a pedal so that when pushed, the table rises. Yung holder ng drill motor para yung kay Martin.
you can also use the SA upside down with the body bolted to a frame and base. Yung shaft can move up and down, di ba? tie your motor to the shaft. Papano ung spring to keep the motor up. Lever type lang. Yung shaft, pa weld ng sangga where you will insert a fork(flat bar) na nakakabit dun sa base na may spring pulling it up.Or wled a tenga sa shaft na may spring to the body. Pang push down,isang lever lang. Clearance maliit lang to dril pcb lang.
Yung chuck, well bili na lang yung smal pcb drill sa Deeco may motor na isa pa, just get the electric drills na surplus. I have 3 units that I bought for P1,500 each. Am selling for P1k walang battery na. may check na, magandang klase pa. Bolt it to a post, then makea rising table. yung rising table on a shock absorber do not need gears opr what not to move up. Cam lang na may lever tapos link to a pedal sa baba. Foot operated pa!
