Flyboy Jim's PM Research #5

Nice! Mandrels and arbors come in very handy, go great with the rotary table.

Nice! Mandrels and arbors come in very handy, go great with the rotary table.   

They sure do! I think before I'm done, it'll be modified to work like the one you did for the Steamer, so I can drill the steam ports.

Lots of variants, caps, expanding arbors, side pins, depending on the part. Essential for gears too.

Great progress him. Still following along quietly.

Hello Jim,

It is taking shape very nicely and some really nice machining work 

Have a great day,
Thomas

You've made some great progress this week, Jim. It is good to see! 

I agree that studs and nuts would look the best on the steam chest cover, and possibly on the head as well.

[Flyboy Jim]

Thanks guys. I'm gradually getting a little more time in the shop. Now that I'm walking again, things are progressing a little faster. 

I turned the cylinder around on the arbor and worked on the other end. Drilled and tapped the mounting surface for the Valve Gland.





Drilled the mounting holes on this end. Have I mentioned that I love my Rotary Table? 



Got started working on the Valve Gland.

I'd say that you are having too much fun, but it looks like the right amount!   

[Flyboy Jim]

Turned a piece of bar stock to the correct starting dimensions for the Valve Gland.



After drilling the hole for the shaft I moved the chuck over to the RT on the mill and drilled the mounting holes.



Then milled the Valve Gland the proper profile.



Moved the chuck back to the lathe and parted off. Reversed it in the chuck and faced it to the proper thickness. If I'd known how nice the groover was going to part it off, I'd of done it to the correct thickness and saved a step.

Quick progress lately, great parts!

Quick progress lately, great parts!

It was nice to make something out of bar stock.

You get some super finishes there Jim, very nice results.

Nice work Jim!  I am inspired to get back at my shop projects, now that the holidays, and vacation trip, and driving the youngest boys back to their respective schools has all been done, and the snowfall and tree falls have been cleared from the driveway...for now?

Nice work on the gland Jim. Hoping I can get back to my #5 soon, will be following your lead now

I was surprised by the gland. I haven't looked at the drawings for the #5 but when I first saw the gland, I thought the 'boss?' would be external.
Is there a reason why it's on the inside?
