Re: Karstens od grinder help needed..

Well, the good news is I got that .00005" increment adjustment working.. Bad news is I'm finding alot of other things wrong. There is a spur gear with a missing tooth under the table that has something to do with the hydraulic feed system. I haven't cut a spur gear in years, but I'll manage. I'...

Re: Karstens od grinder help needed..

As far as the issue with the “faceplate”, the work head is most likely set up for dead center grinding. The knob on the back of the work head engages and disengages the center allowing it to rotate with the spindle or not. Known as “live center” or “dead center” grinding. I’m not familiar with that...

Re: Karstens od grinder help needed..

The .001 feed lever is just a quick way to I infeed for roughing. When you get close to your finish dimension you use the hand wheel and fine feed adjustment. What you are referring to as the Y axis is actually the Z axis. It only has X and Z. I only mention this as it may be confusing when trying ...

Re: Karstens od grinder help needed..

This is the .00005" inch adjustment knob that I'm having an issue with. It only moves the Y about .00025" then stops turning. I would think it should keep turning?? Not sure. Never fooled with one of these machines before and I'm just starting to figure it out.. like the knurled knob in th...

Re: Karstens od grinder help needed..

Disassembling and derusting in progress... don't think the grinding head was ever pulled, what a mess.. but it's cleaning up good... using eastwood afterblast and a scotch brite pad to remove the rust, followed by oil and a scotch bright pad, then wipe down and more oil !!

Re: Karstens od grinder help needed..

Ok, let's see if this works now... I resized the image of the headstock.. there might be an issue with this aluminum ?? Well best I can call it is a face plate. I think it drives a lathe dog, but it just spins freely and feels loose like a bad bearing or something. The rusted steel part rotates with...

Karstens od grinder help needed..

Picked up an old karstens id/od grinder and I'm looking to find some information on it. A owners manual would be great!! Just doubt I'll find one... just trying to get a handle on how the controls are supposed to work. The Y axis has a .00005" adjustment knob in it, that only seems to move the ...

Re: Casting sand

The petrobond I use to cast has lost its strength. After a lengthy discussion with Lancaster Foundry. A phone call to Lancaster foundry is answered by a nice lady and when my questions got long she transferred me to the owner who was more than just helpful. In order to restore my petrobond I would ...
