Drill Press

thingiverse

This thing is designed around a small kit available on Amazon and other places. For around $12 the kit includes a small motor, adapter and a very nice copy of a Jacobs No 1 chuck. There are also leads with spade terminals to connect the motor to a power supply and a half dozen assorted drill bits. With this kit, a power supply and these printed parts you can make a mini drill press for your workbench. I've provided holes which can be tapped M3 if you wish to add a small PWM motor controller, also available at Amazon. UPDATE: July, 2022: THE THINGIVERSE WEBSITE IS BROKEN I've changed the design to eliminate the M4 eye bolt but I'm not going to post any more files on thingiverse because THE THINGIVERSE WEBSITE IS BROKEN - - The main column is just a length of stock 20-20 extrusion; around 200mm is more than adequate. - - Please click the "LIKE" icon! :-) Now some notes on printing: - - PLA is perfectly adequate - - Print all parts in the position they are downloaded - - DP_Column_Cap_03.stl needs support 'touching buildplate' - - DP_Quill_Body_06.stl needs support 'touching buildplate'. It's got pockets for a pair of bearings to support a 5mm shaft that holds the pinion and handle hub. Either plain or flanged bearings will do. - - DP_Quill_Cap_03.stl should print reasonably well without support but use your judgment - - DP_Rack_06.stl needs to be printed with a brim and after it's done and the brim removed you'll need to clean up the bottom of the bevel with a rout-a-burr and file to remove any remaining ridge. - - All holes can be tapped M4 but do use nuts where possible; i.e. on the bottom of the base and the table. --The counterweight bucket can be attached to a cord with a bit of bent wire through the two holes. The other end of the cord can be attached to an M4 eye bolt or looped over an M4 bolt and under a washer. The bucked can be filled as needed to balance the Quill-Body, using sand or coins. - - The 5mm shaft that supports the pinion and the handle hub needs two flats ground onto it to seat the setscrews that fix these parts in place. - - I'll provide a list of fasteners when I get around to it; meanwhile use your own judgment. :-) Sources: - - Motor kit: https://www.amazon.com/dp/B01LZYWFE4?psc=1&ref=ppx_yo2ov_dt_b_product_details - - Speed Control: https://www.amazon.com/dp/B07MK1SKRT?psc=1&ref=ppx_yo2ov_dt_b_product_details - - Bearings: two: 5mm id x 14mm od can be press fit into the sides of the Quill Body. - - 6: 5mm id shaft collars to keep things from falling apart - - 2: 5mm x 30mm steel shafts for counterweight pulleys - - 1: 5mm x 75mm steel shaft for pinion and feed handle
