Setup and Continuing Saga of the Charter Oak 12Z

[wrmiller]

Bill if you get a chance one day can you post a close up pic of your replacement right hand mill handle? I'm wondering how you integrated with that three jaw like dial. I suppose you could chuck that in a lathe or mill and machine that off. I'm just curious no hurry.

I WAS going to mill the end of the replacement handle to fit that three-jaw like dial (thanks, didn't know how to describe that). Then decided that was probably overkill and more work than I wanted to just replace the handles. Then after talking to Paul and realizing that I no longer need the dials after installing the DRO I thought about taking the whole shebang off and making some spacers to replace the dials.

But then I decided that I don't want to replace and/or modify the original setup 'just in case' I might someday need it. So...after taking one of the handles off and just looking at the end of the shaft (about 3/4" sticking out) I decided to bore the handles for a snug, slop free fit, drill and tap a 10-32 hole perpendicular to the bore, file a flat on the side of the leadscrew shaft for the setscrew interface and simply slide this puppy on there.

It slides right up to the dial sleeve and the setscrew cinching down on the flat will prevent the handle from turning on the shaft. The handle is not an interference fit but it is snug with no tilt/slop once it's on. Even without the setscrew.



As you can see, there is plenty of engagement between the shaft and handwheel.



Not the most elegant solution, but it is simple yet functional and doesn't destroy/modify the original design in case I ever need to use the original handwheels again. One benefit of doing it this way is that it gets the Y-axis handle a little further away from the edge of the chip tray and the end of the vise. )

Nice to get rid of those plastic handwheels. I wish machinery manufacturers would charge an extra $100 and put classy hand wheels on these things. My Grizzly G0709G lathe has aluminum hand wheels that I really don't like the shape, feel, or look of. CI hand wheels are in my future.

But then there are people who would bitc$ and moan about that extra $100 cost. Can't please everyone with only one configuration.

It WOULD be nice for those of use who appreciate things like this for it to be an optional upgrade though. )

Here are those pics of the belt drive as promised. Sorry for the delay. Been hurting pretty bad today.

I have one more picture of the motor pulley but I need to learn how to manage my pictures. I don't have room to upload it.

There is some limit to the amount/total size of pics you can load until you get to a certain post number.

Very nice pics though. Now I want mine to get here...

EDIT: Just a suggestion, but if you reduce the size of your posts to say 1280x1024 people can still see detail but the file size drops dramatically.

I got rid of one yesterday...if fell off 20 inches to the floor and broke in half (face palm)

Haha, I guess that's one way of doing it. :lmao:

When I got my PM45, one of the handles arrived chipped, still useable but of course not acceptable. They're made of a bakelite/phenolic type plastic so they can chip or crack easy on moderate impact or getting dropped. Of course a replacement was sent out immediately. Well it arrived chipped too. The next one made it ok. I was thinking about using the hubs from the damaged ones some day to make new hand wheels, the hubs are metal. But I kind of like Bill's hand wheels & may have to steal his idea.

Hey Bill, do the handles on your new wheels swivel (rotate) or are they fixed?

Thank you so much for relating your setup experiences with this product.

Our members want to see what's involved.

I agree. I had purchased the Bridgeport ball crank style handles after ordering my PM-932PDF due to that very fact, I wanted something a little nicer and better quality. Had I ordered it that one if it were an option? Possibly, depending on the cost but I know there are others who would have complained about the cost.

After changing my order to the PM-935TV which already had that style of handle I merely sold them for what I paid for them but if I hadn't changed my order and had a PM-932 sitting in my shop, it would have the new handles on by now.
