Just added a rear Chuck to my Porper B-Lathe

I recently purchased a number of extra Porper B-Lathe parts from Eric Winn, if anyone else has a Chance to deal with Eric, don't hesitate he is a stand up guy, and pleasure to deal with.

Included in the parts was a standard chuck for a Porper B-Lathe, a tool post, and a Indexer. I contacted Porper and purchased a mounting bracket for the chuck that was included with the parts. The Mounting bracket cost $55 shipped to Washington State, and it arrived the same day as the others parts which was really great.

The installation of the rear chuck took approximately one hour, and when installed zeroed out at slightly less than one thousandth which is better than I expected. I really like the accuracy that dual chucks give when absolute precision is required such as facing joints.

If anyone else out there has a Porper B-Lathe and has not put a rear chuck on their lathe I would certainly recommend it, and don't forget you can buy a mounting bracket directly from Porper which will ease installation.

Take care
 
It looks very nice, How is the vibration running high speed, does it walk across the bench?

Actually, it has less Vibration than it did before, I just did some coring and I was surprised that the Vibration was actually reduced a great deal. It may have something to do with the run out of my chucks, when I installed the rear Chuck and I also removed and reinstalled the front Chuck. I chucked up to a dead Center with 3 inches exposed, and put a dial indicator near the end. The front chuck dialed into to 0 thousands with no problem, the best I could get out of the rear chuck was slightly less than one thousandth out or almost zero needle movement.

I am not an expert, however, it seemed like a good idea to zero both chucks when the second was added, it may have done nothing at all, but I do certainly have less vibration than before not more. Should it Vibrate more Mike or did I just get lucky some how?

Thanks for your comments Michael

I am glad it didn't but I expected it to on high speed because of the added weight. One reason I thought the one from Brianna would be better, because it is light, Nice to know both set ups can be used.
Thank you

You know the more I think about it Michael, I wonder bar for the steady rest that comes off the back of the lathe also helps stabilize the entire set up. I just checked the lathe when running on max speed with the router attached, I have virtually no vibration other than that caused by the operation of the router.

Again thanks Michael.

For not being a set true 6-jaw chuck, that's mind-boggling.
Best I get on 6-jaw set true Bison chuck is about a little less than 2-tenths.
Less than that will have to be a collet-closer territory I think.

That's a great setup there you have.

Thanks Joey, I am really happy with it, I suspect it was the best decision I could have ever made.

Thanks for your post.
