Just picked up some Silver and Demming style drill bits (reduced shank) from Drillhog; 9/16 to 1". Games Green has reviewed them. They work well and were only about $60 off ebay. I made and ER40 chuck for my Atlas/Craftsman 12x36. Works well. I made mine for milling cutters to use the milling attachment. I find I use it more often than I expected.
I had a lot of difficulty with runout on two chinese ER 32 collet chucks. I found the problem to be in the chinese nuts. I curred my runout issues with a "Bearing" type nut. I bought off ebay for a reasonable price. Near "0" runout Also the lock up with the bearing nut was much easier with the bearing type nut Thanks
Great video, well shot and narrated. Thank you. Another advantage of ER over C is the ER has two angled bearing surfaces instead of just one. This increases the purchase and clamping force on the part.
Good video. Interesting that your ears are a measuring insturment for speeds and depth of cut. I have much better hearing than eyesight, and I hear chatter, howling (resonance/harmonics) long before I see them.
Yeah you can usually hear the chatter happening. You can also hear rubbing really easily on boring operations. A lot of times the camera picks up a high pitch squeel during boring that I cannot hear over the machine itself.
Greg, Nice job! Why buy tooling when you can make it, right? There's nothing like building your own Christmas present! More comments in Part 2..........Dave
Thanks, great video. Question on your tooling. You are using insert and getting good finish. I thought good finish with carbide needs high speed. Does your South Bend go over 500 rpm? My 13" Le Blonde peaks at 500. Can I use carbide? Thanks
I like the video thanks,,, I have made one last month also I have had to make the nut itself it is a little bit tricky to done but that was fun I have made three set for wooden rotary CNC also, And it works greatly.
i am planning on doing a similar project for a pool cue lathe i am building (my 46 logan 820 does not have enough bed length or bore size.) but the collects are going to be delrin or some other plastic. this will be a great help thanks.
thank you for the insight on tge collets, ive been kicking around which set to go after to use between the mill and lathe. and you just kicked the 5c's out the window, though spin fixtures and what not would be an easy add on running 5c.
Oh my God I can dial in a 4 jaw Chuck pretty damn fast but that's got to be the coolest trick I've ever seen. So let me get this straight first you find the low then the high and then the nearest jaw to the mid-range set that is 0 and then go around and set the rest of the Jaws to zero?
Hi Greg, again a nice vid. You are mentioning your email address as the best way to contact you for questions. Did I miss the address or didn't I looked properly.Teun
One thing that is hard to find out is how many and what sizes do you need in ER32 collets to span from say 1/8" to 3/4" and cover everything in between in 64ths? I know I could figure it out but ... Will a set in 1/16ths do it? Are they really all metric but just relabelled in imperial?
This is some time later I admit but no they are not all metric. If they are labeled in inch they are in inch. I have some metric stuff that simply won't fit in any of my inch ER-32 collets.
5 collets can be bought soft and bored ...harded ones can be bored also rockwell is not that deep ir hard there is a article in home shop machinist on how to make a 5 c set up for the 10..12 inch atlas/chraftsmann/clausing/southbend/logan lathe
I made it a while back before I had a mill. I paid for a night class at a local tech school to get some mill time and made the block and the fingers for my steady rest so I do not have a video. I will be making an improved version for the 13" lathe so stick around.
I read the comments and noticed nobody corrected you on ER collet use. The collet is snapped into the nut and then screwed into the chuck and the workpiece inserted in the collet. If done the otherway could damage the unit. This is a good subject to show and I'll be watching intently.
I've been on tenterhooks since the last video, and i'm so pumped for this project. I've recently got my first lathe, and I'm so excited to start making stuff with it, including some cool shopmade tools like this one
Best place to start off is learning to grind some toolbits. Mist of us out on RU-vid have a video of our own personal way of doing it. I have one on this channel available in the beginner video play list.
