Topic tags/keywords: tip trick

Have FINALLY been able to get the chuck rebuilt and operational on the Goodell Pratt drill press from earlier posts. This has been by far the hardest part of getting the old girl back in service. There has been a lot of trial, error, sweat, tears and profanity involved, but also some amount of luck.
The chuck itself as received had no jaws. (Start of cussing here). BUT, I have a Fulton two speed breast brace with the same style chuck, which didn’t work anyway. EVERYTHING had to be soaked in WD-40 to get it disassembled. OK, the Fulton had the three jaws, but only two springs, one of which was badly distorted.
Redneck engineering time again. I recently bought 8 ball point pens from the Dollar Tree, specifically for the springs (I’ve found several uses for them) LUCKILY, the springs were the same diameter. Trial and error, cutting off 2 coils at a time, eventually got them to the right length, where the jaws fit in the shell nicely. Things were looking up!
BUT, The top part of the chuck, the part that screws onto the spindle, would not go up onto the threaded rod far enough to close the jaws effectively for smaller diameter drill bits. (Insert a LOT of un churchly verbiage here) I suspect the threads have gotten messed up at a certain point on the spindle.
Redneck to the rescue, one more time. Some washers were placed between the top of the jaws and the metal cup shaped piece that goes on the inside of the top of the jaw chuck. (These parts have names, but I don’t know them) The washers did the trick! The chuck is now fully operational again, and I’ve drilled my first few inaugural holes with my “new” antique drill press! I’m as happy as a hog in a waller that with a little “jerry riggin”, and a LOT of cussin’, I got ‘er back working again!
I’m sending out a great big “THANK YOU” to Old Sneelock, for his YouTube video on rebuilding a Millers Falls breast drill chuck. This gave me enough information to get this project done successfully.
BTW, Don’t worry about the Fulton. I have another chuck floating around somewhere that should fit it just fine, even if it is for square tanged bits.
