spindle

Hey y'all! I just finished pulling apart, cleaning, and re-greasing my Unimat DB200 headstock spindle, and now when I run it, I'm getting a high-pitched sound coming out of the chuck side. I followed instructions and put everything back in order, re-greased the bearings (SuperLube), etc. and...

I have a G0776 lathe and have been experiencing a large degree of runout and vibration on the spindle. When a chuck is attached it wobbles to such a degree that I have excess vibrations and can’t make any accurate cuts. I’m wondering what could be causing this. I have taken some videos to help...

Alright, I figured I'd get into some lathe work. . . So I went and bought an ENCO 110-1351 that had its own home made CNC on it. Was sold to me as working order. Figured great, I'll get to start playing around! NOPE. hahahaha. Which is all good. Massive learning curves are fun. So, machine...

Hi there, I would like to share my setup to grind the spindle taper, may be it will be useful to someone. It was very badly pitted apparently from years of misuse so I got the carriage of my small lathe and the grinder.

So I bought a china spindle spindle motor package for making a tool post grinder. Its a brushless DC motor and most of it came prewired except for the wires coming from the motor. The seller does not have a wiring diagram. Through my research and looking at pictures, I have concluded that it is...

Hi there, I am putting back together my VN-12 as previous owner disassembled it to move so now, I have plenty of questions. Good news are that all the gears seems to be in great shape. Since original motor was scraped I got locally a 3HP 1780 RPM motor, is it suitable for this machine? what...

Good Afternoon Hobby Machinists I am going to be moving in a 1957 LeBlond Regal lathe in a few weeks. I am excited!! It is an early “square head”, 13 x 42, which actually turns a little over 14 inches. I may be completely crazy, but for a machine from a company that is still in...

Taking a buddy's advice that I should start documenting my projects, thought I would share a bit. Brief intro, I've been dreaming of building a CNC mill for a while. I have a closet full of servos, control boards, linear rails, and other misc parts. I had been designing a weldment frame, but it...

Hi folks, I have a question about my lathe that I seem to get a lot of conflicting information on when I scour the internet. It's about the spindle taper dimensions. It's really unclear what exactly I need to suit my needs with regards to a 5C spindle adapter. I have read countless times that...

I have no idea if this is the right place for the build thread, but my home is above my shop, and this CNC project will be in it :) I'll say up front this is a big, big project. Especially for something that's only the size of an oven. This first post will be a sort of rolling summary (so...

On my SB 10K the leather belt runs true when the lathe is turned on. I notice when I start machining the belt moves about 1/8 of an inch. Always in the same direction. Is this normal, an indication of something wrong, or can an adjustment be made to stop the belt movement? Thanks in advance...

Hello everyone, I'm new to the site; I've been out of machining for awhile, but have recently been tooling up. I just added a 20" Rong Fu VFD drill press to the shop and it arrived a little worse for wear. The depth stop handle was broken off, as was the electrical box holding the VFD. I...

My collets have been rough going up in the spindle . I looked up in there and the little R8 aligning grub screw is a little bit galled over. I'd like to remove this grub screw but can't figure out how. I removed the quill base but see no way to get at the grub screw. I called Matt earlier this...

I am nearing the end of my 9A disassembly. The rebuild manual specifies loosening the two 3/8 bolts on top (done) and removing the take-up collar and washer (done and didn't have one). I tried a few taps with my 2# dead blow hammer on the left end and then got aggressive. No amount of force I...

So I pulled the head apart and there is no safety wire on the ring gear bolts it looks like they aren't even all the same type some are all thread some are not. The cavity was full of what looked like moly grease and there was no oil in whatsoever. I examined the upper bearing and it seem to be...

HI my name is joe. I am trying to replace the main v belt on my craftsman atlas lathe. I have taken the outer ring and gear off of the spindle shaft. But the woodruff key will not come off the shaft. I have used pliers and everything I can think of to get it out of its slot. I need some advise...
