I can't see a name but it is the same as most of the 9X20s. It looks exactly like mine but that is not a Jet. Central Machinery was that color blue. I think the Enco was to.

I figured if I needed parts they would likely enter change. Being i am looking for a mill not a lathe, the price dont hurt my mill budget much either.

Thanks for looking. Keep up the awesome work.

Bill this is the 5" vise I told you about and my Dad is going to send me info on the 4" he is using now.
As you can see it's almost as high as my Bridgeport vise about 5" high and the swivel base is 1 1/2" high.

5 in hi, 12in long, 4 in jaws wide, 5 - 6 in jaws open is what he told me about his 4". I'm thinking the problem is not the height but the over hang if you notice the vise is in the front t-slot so he doesn't lose travel on Y-axis.

One more time I when out and checked from the front edge to the mount bolts is 6" so once it's mounted even in the front slot he felt he lost to much travel.

Sorry guys, things have had to be done in that last few days that just had to get done. There was little time left to work on this. We will resume again very shortly. Again, sorry for the delay.

Good news the other 8 books on Workshop Practices Series showed up today, takes about two weeks from Abe Books. Now I'll have to sit down and read them all first is the Spindle book you talked about.

Good to hear Todd. Please let us know what you think of the Spindle Book.

OK we are back at it. These will become the Spindle clamps. They are mirror images of each other. The mill is incorporated here for its accuracy over the Drill Press. Three of those holes will have pins in them till the parts are finished. As I said they are mirror images. All of the work on these will be done with my milling machine.

Interesting - will nylon pins really hold those two plates together securely through the rest of the machining? I would not have guessed that... but that's all it would have been is a guess. I'm curious, is there any rule of thumb you used to know it will work, or is it just based on experience? Thanks.

It is based on past practice. If it were just one or two it would probably fail at the worst possible time. Being three points I have complete faith in it. I don't like to bolt parts together like a lot of machinists do. Also the three hole will be for something else later. It's one of those things that I do and have done that works for me. Hope this answers your question?

2.253 and done. Just shape it now and these parts are complete. Yes, that's a flycutter. They make great boring tools also. I reset for the next cut with a Dial Indicator. I cut .100 at a time. The nylon plug locators are rock solid as always.

I have a Clausing 8520.

Just the lock screws and these are done. They are a nice slip fit.

No corner rounding? Slacker! :))

Do you use Tef-Gel on ss threads in aluminum? That's what we've found to work best in a marine environment.

First two screws are in. I have to ask my scrapper what they used to cut this stuff. The edge looks like it was cut on a table saw.

If I am understanding you correctly the only holes that were predrilled were the four on each wing. They are #25 tap drill size for 10-24. When clamped they were used to guide the #25 into the back. Then tapped.

That's her "What the hell are you doin" face.:rofl: I also find it easier to post when I take a break from an operation.

OK--- The back is now square and perpendicular to the Spindle center line. This, for you new fellas, is an extremely important operation for a smooth drive. Again, the flycutter is you best friend.
