Machine Party: 六月 2008
http://machineparty.blogspot.com/2008_06_01_archive.html
This device is actually a more sensitive and accurate water level. Which has a precision ground bottom surface, normally with V shape channel at the bottom for standing on round objects. With a precision made water level scale. This level can show 4 seconds of inclination change. You don't need to use a flat reference surface to zero it. Just simply place it on a clean, rigid surface.Shim the surface to roughly flat level, then the water bubble will move to somewhere in between of the scale. This blog is...

Machine Party: Homemade Anti Backlash Nut for sherline machines
http://machineparty.blogspot.com/2009/06/homemade-anti-backlash-nut-for-sherline.html
Homemade Anti Backlash Nut for sherline machines. Since last summer, I tried to make anti backlash nut for my machines. There are two major sizes of drive screws on my machines. As my machines are in metric scale, sherline cut the standard M6 1mm pitch thread on the drive screws and nuts, but they are using the 0.25 inch (6.35mm)and 0.375 inch (9.525mm)diameter stock to make the screws. This result in unique specifications of threads. Thus, I decided to make my own tap. I cut the taps from sliver ste...

Run out of 3-jaws chuck. Normally, no one will re-chuck the work piece to turn both ends, unless it is absolutely necessary. Especially re-chucking the 3-jaws self centering chuck will make you get into trouble. But, checking the run out is another thing; it can be performing very easily. I am going to use an edge finder to check the run out. Some people will use a drill rod, or the clamping end of the drill bit. All of them are work, as long as the testing rods are straight and concentric. Sherline make...

Machine Party: Magnetic base mount
http://machineparty.blogspot.com/2008/05/magnetic-base-mount.html
Sherline makes tables from extruded aluminum; I need a little piece of steel plate for the magnetic base of dial test indicator. After I’ve finish this plate, I find that, if I put screws in both of holes, there will have no space for the magnetic base. So, I can only remove the front screw, let the weight of magnetic base press down the steel plate. It was rigid enough for my works. I suggest using a larger steel plate to provide enough space for your magnetic base. Title： Custom accessories.

Machine Party: Gib fitting
http://machineparty.blogspot.com/2008/07/gib-fitting.html
This is properly the first problem I've found in this lathe. When I wind the cross slide hand wheel, the cross slide moving with rocking. And this can be easily observe by eyes! Then I decide to take the cross slide off and see what's wrong. The gib was a bit higher than the dovetail. That means, the cross slide cannot sit down properly on the saddle. What I am going to do is file the gib down. Put it deeper into the taper space will press it upward and push up the cross slide again.

Machine Party: Lead screw end support bearing
http://machineparty.blogspot.com/2008/07/lead-screw-end-support-bearing.html
Lead screw end support bearing. After I've taken out the lead screw, I found that, the end which close to the headstock was directly inserted into a tube. Without any bushing or bearing support, I can see there has a scrap mark on the inner surface of the tube. And it was definitely a thread scrapped mark! Luckily, I find a 12x8mm bearing on hand, and. Turn the lead screw end down to 8mm and bore up the tube to 12mm. 訂閱： 張貼留言 (Atom). Lead screw end support bearing.
