First of all I really like the tube amp link. That's something I will have to build some day down the road. Tonight I was able to get in to the work shop and play around with the lathe. After a few tries I was able to get a part made at 50% of the size that the finished part will be. There is just a fine line where the taper and radius meet, but that should easily go away with a bit of polish. I was just about to run the full size part when I ran into another snag. The part will not fit in the chuck so I bought a chuck back plate to use as a face plate and simply bolted the part to it. The trouble came when I tried to mount the face plate to the lathe and found that the face plate is 1/8" too short to fit. The nose of the lathe sticks out of the face plate! Now it looks like I will have to make up an adapter to hold the part out from the face plate so the nose of the lathe has room to stick out. I'm really bummed as this was an expensive back plate make by South Bend and I was planning to re use it when this project was done to mount a new chuck for the lathe. Now it looks like it will be a $75.00 piece of scrap metal. Here are some pictures. Dale P. |

Dale, Don't give up on the back plate, you may well be able to recess your new chuck to fit! On a chuck, the area around the base where the spindle is rarely critical. Back plates are ideally cast Iron to prevent locking on the nose thread. If you make a steel spacer for a new chuck, a thin plate would suffice, pinned to the back plate. I'm tempted by by your speakers! Regards, Matthew |

Thanks Matthew for the advice about mounting a future chuck. Your probably right about making a recess on the new chuck, it's just something that I shouldn't have to do with a new chuck and back plate. I send Grizzly a picture and asked them to add some dimensions to the web site so people could see what they were buying. Right now my main issue is mounting the Top Hat parts and the adapter that I will have to make so they can be mounted to the back plate. I really want to cut the full size parts out and see what they look like. Dale P. |

Dale, I understand what your saying about "I shouldn't have to do it on a new chuck" but I feel that machining is about making things work! Machining a backplate is just about making it fit. Regards,Matthew |
