Nice, you’re leading me the way. I had just realised I got fed up with manually cranking my Unimat 4, which has no leadscrew disengagement option, back and forth over and over again. So I want a fast speed to simulate the disengagement option and a slow adjustable power feed as an added bonus. So I am paying close attention to your work!
Hi Ade I have recently bought a Warco Super Mini Lathe including a 4952 QCTP (?) but am struggling with it. I cannot see how the stud that screws in to the holder is locked as even if you lock the knurled adj nut with the cap head screw the stud can still move in the holder. Am I doing something wrong? Sorry can’t send by facebook as I don’t use it.
Hi Michael . I am not familiar with this tool post but I am guessing that you need to lock the studs down hard into the toolholder before fitting the adjuster and lockscrew. Perhaps use two nuts locked together to tighten them down and maybe use some threadlock in the hole. Hope this helps . Cheers Ade.
At 1:40 when turning that first pulley it looks like shaft hole in the pulley was not centered? Won't that make the entire job have some runout? I love your youtube channel by the way. 🙂
That hole is only a clearance that allows the thread inside it to be shorter . The arbour screws on the thread on the end of the leadscrew . It does look a little worse than it is due to the burr in the hole from facing . I have tried it as an assembly on the leadscrew and although there is some runout due to the leadscrew threads , it is true enough for its purpose . maybe less than 0.1 mm . Happy days . Cheers Ade
Hi Ade, I want to do a similar project both on my lathe and my mill. I’ve watched all your videos on the subject and you mention links to the necessary parts. Please can you point me in the right direction to find the parts list. Also have you ever done a video on obtaining materials for hobby machining? Love your work and the relaxed style of presentation.
When this is finished, you'll only be a hop, skip and a jump away from an electronic leadscrew installation. A very worthwhile addition to the lathe if my efforts are anything to go by. All the best, John
Hi BR , maybe when I eventually change the motor to a 3 phase with a VFD I could go down that route . In all honesty though , I don't do a huge deal of screwcutting . Cheers Ade.
It’s funny I just watched a video yesterday of you building that bench behind where you set and you were talking about your sticker board thinking about putting it where it is now. I love watching your videos, you do such great work, as always thank you for your time and knowledge.
