Single Pulley has two brass machine screws holding it to the spigot. The double has two "Dutchmen". On to the grooves.

Where is RayC? 30* included angle, 10* side rake both sides. Needs a 1/8" radius on the nose with the same rake an we can cut the grooves. That is hand ground folks. You could shave with that edge. :lmao: The tool is 3/8 X 3/8 X 6 Cobalt.

Nice job Bill!
I learned years ago it's not worth my time to hand grind it's seems to me with all the sine bars and toolmaker vises I've been able to grind the tool the repeat again if needed. I'm probable spoiled with my surface grinder but I like the repeatability when grinding a tool of that nature. Again that's a great job you did by hand.

That's it for the Drive Pulley. The groove profile looks much better that that. I didn't hold it straight. The slight angle makes it look funny. Sorry.

I'm going with 3/8" round belts also. My local hardware store carries it. It is continuous length and you epoxy the ends together. I have never seen a joint fail.

Both are done now. I believe they are the last two parts. One more check before final assembly. It's been one heck of a journey.

Bill could you provide a link or a name for the belt.

Thank you David

Nice job! For a note to ponder. The Levin manufacturing company (for example) has found that a 53° included angle works best for round belt drives. Apparently this angle has been found to have the best grip.

First run up was a complete success. Ran it for 15 minutes. Tomorrow I will reset the preload on the bearings or at least check it. Pictures to follow. I am extremely happy with this project.

Well Bill I am sure I speak for many of us that have followed this thread, when I say I have been very happy following this, and when it is all done will have withdrawal symptoms for sure.

Can't wait to see it in action.
All the best

The catch basin was first. Parts were purchased for this. I stumbled onto the SS part at Walmart. The assemble Pic #2. The drain pipe had to be modified to accept the strainer. The bore was opened up .060, 1" deep. The flange was made smaller and the inside radius made smaller to accept the rim of the strainer.

Definitely near the finish line now! What a pleasant and educational journey it has been!!
Hear, hear. The only way to improve on this would be a field trip to Bill's house for a personal look.

With a good belt and the bearings preloaded again, I ran it for 20 minutes and checked the run out at the nose. It is less than .0001. I used a .0001 gage. It is good to go. This may or may not hold, it depends on bearing wear. Only time will tell.

Over the next few days we will button this project up. For the most part it is finished. A belt guard must be made. The apron and legs done and the plumbing installed. At this time I would like to thank the 600 people that visited this project. It has been my pleasure to do this project for you viewing. I did it for two reasons, the obvious being I needed one. The other was to show that the big machines are not really needed on a project of this magnitude. All I have are a Clausing 8520 Mill and a Jet 9X20 lathe.

I will continue to post as I finish up. Today I will take on the apron parts then the legs. The legs will be adjustable to level the machine.

Bill there are probably more statistics in the "thanks" and "likes" section, but it seems to have disappeared.

The drain plumbing was a simple matter. Now on to the Coolant Feed line.

That's excellent Bill. Do you recall the part number of the bearings you used?

I appreciate it Bill. I am working on the design for a 4th axis, and I keep vacillating between tapered rollers or angular contact bearings. If the bearings you are using are reasonably priced, then their larger brothers may be an option for me, otherwise I will go with my current plan of angular contact bearings.
