night of the 3rd shop built rotary valve and chuck.. Mac https://home.comcast.net/~mac.davis https://home.comcast.net/~mac.davis/wood_stuff.htm |

Not sure where the rotary valve is specifically on your site. I check the
links off woodstuff.htm but didn't spot it. Derek |

Hi mac
It would be easier for us if you put it on your website. I have been to the abpw and nothing yet, the last pic. from you is a stitched up platter, don.t know how long ago you posted that ?? it is right in the last page, 10 pictures or so from the end. http://homepage.mac.com/l.vanderloo/PhotoAlbum28.html Have fun and take care Leo Van Der Loo |

I'll try to put some on my site, but when you do web pages all day, it's hard to get enthusiastic about them at night... Damn good thing I didn't go into OBY/GN!!

vacuum chuck testing
Hi Mac
They just showed up, the pictures that is. Looks good, you used a plastic end cap over the bearings I think ?? with the brass elbow in it. What you use for the inside, into the spindle, copper/steel pipe or something else ?? Nice small clear bulb filter, makes it easy to see if anything is in there, and you have a bleeder valve on the front side I suppose, can't see it in the picture. Next chapter in your quest for more round wood GG. Have fun and take care Leo Van Der Loo |

What you use for the inside, into the spindle, copper/steel pipe or something else ?? My first attempt, which Bill Noble warned me would wear out quickly, was simply a compressor quick disconnect, and it wore out pretty quickly..*g* I lasted long enough to try a few chuck designs, though.. The 2nd try was a PVC joiner section with a bearing in each end, but I found that 2 bearing aren't needed... all you need is yo isolate the handwheel from the vacuum fitting... I threaded the inside of the spindle to fit a brass gas fitting, then used an adapter to get the thread size up to the inside diameter of the bearing.. I think it was .625".. I put the fitting in the lathe chuck and tapered the threads off the larger end of the fitting with a file, then used thick CA and a jam fit to fasten it to the bearing... I picked an end cap that was slightly too small for the outside of the bearing, put it in the chuck and widened the end at a taper with a sharp mini-skew... While I had the cap in the chuck I drilled a 5/16 hole in the end of the cap for the compression elbow.. It's still not a GOOD valve, but it works and has no leaks so far... It would be MUCH more time efficient to just buy a complete system or have Bill make one up, but it wouldn't be nearly as much fun.. *g* Nice small clear bulb filter, makes it easy to see if anything is in there, and you have a bleeder valve on the front side I suppose, can't see it in the picture.

Hi Mac
You say it's still not a good valve, I don't agree, it does not leak, it works, and it is KISS, what more doe you want ??? A tool that works is a good tool. Yes the quick connect/disconnect is not made for that kind of swiveling, even I could have told you that G, but they sure are nice to have, so you are able to take a part, piece,gun,tool, and switch for another or just take it off and store. Time and efficient, Oh, well that would mean I would have to go and buy my turnings, noooooooh I'm having to much fun. Have fun and take care, and thanks for sharing. Leo Van Der Loo |
