Flyboy Jim's PM Research #5

[crueby]

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?

To press in on the packing, gives more compression adjustment before the flanges bottom out.

Speaking of packing...............there wasn't any included in my kit. What would be good to use?

the graphite cord packing like used in faucets is good - the narrow kind, or take the thicker cord and untwist the strands to get a narrow length, wrap it around and let the gland compress it a bit. Or even o-rings, if one happens to fit the space. Even teflon tape, twisted into a cord, can work.

Perfect.............thanks Chris.

Made the final push (I think) on the cylinder.

Milled the opening on one end of the Cylinder where the steam port will enter.



Set the Angle Table to the required 20 degrees and nervously milled a 1/8" flat and then drilled the steam port to intersect with the milled slot in the steam chest. Came out right on!    Then flipped the Cylinder and repeated the operation with the same result. 





The last operation on the Cylinder was to drill and tap the steam outlet to intersect with the slot in the steam chest. A little clean up work on the casting and, other than some possible honing of the Cylinder bore, this part is done!



Next up was finishing the Inner Head. Chucked it in the 3 jaw and turned to proper thickness and then formed the boss.





Two parts finished in one day.

Nice work Jim, I understand that feeling. Feels good doesn't it?

[crueby]

Excellent!! You are well and truly hooked and on a roll!

[Flyboy Jim]

Thanks Stuart and Chris.

Time for a little change of pace, so I tackled the drive pulley.

Chucked it in the 3 jaw and turned that ugly wart off.



Moved it to the 4 jaw and indicated it as best I could. Set up the Compound and turned the outside half to the correct 5 degree angle.



Turned it around, mounted it in the 4 jaw and indicated it for turning the other half.



Drilled and reamed the bore.



Mounted the RT on the Tilting Angle Table (set up at the proper angle) on the mill and then moved the 4 jaw over. Milled a small flat and then drilled and tapped for a set screw. Rotated the table two spokes over and did the same operation again.





Mounted a shaft in the lathe and mounted the Drive Pulley on the shaft. Checked the run out. It was 0.005". I can live with that! 



All in all a good day. Plus ...........I was able to put on a running shoe for the first time in 5 months!

Always happy to see an update on this one Jim. Wonderful progress and very nice looking parts as well.

It's looking really good. 

Time for a family shot?

[Flyboy Jim]

Thanks Don, Bill, and Zee.

Since I was on a roll with round things, I turned the Flywheel  today.  Not many pictures since it was pretty much just the same procedure as the Drive Pulley.





So now by "popular demand"  here's a "family picture" of the progress so far.



Jim

[crueby]

Woohoo, really got the swarf in full production!




Is that the last of the roundy things, just some slidy things to go?

[Kim]

Beautiful family portrait there Jim!  Love it

Hello Jim,

Looking really good, have you decided on a color scheme?

Have a great day,
