parts for an old time genny.

[steamer]

Sorry Joe!

Dave

That's OK Dave...

This is me , you and kermit: *discussion*

It was good to see that somebody else would do it that way ...
now I don't feel so alone :big:

Cheers, Joe

 

[steamer]

Anyway that gets it done is the right way Joe.....no time clocks here.

So I take a piece of 5/8 brass rod and cut about 2.5 inches off. Face it up and center drill, drill-tap say 1/4-20. The turn down a shoulder to a 1/2 inch(tight fit) for a short distance say 1/8 inch and use a bolt and washer to hold the parts in place on that tiny 1/2 inch end.

Is that about it?

(A big grin just came across my face) I'm a litte embarrassed as in hind sight that seems like such a simple thing. NOW, it is a simpler thing. One of those hit yourself in the forehead moments.


Thank you guys,
Kermit

 

[steamer]

You got it Kermit....I would change your approuch slightly..

Use the biggest diameter you can under 1.5". It will grip the part better

Dave

 

[joe d]

Is that about it?

Yup. ;D

Edit to add: Dave: you beat me to it again....

OK Joe....Sorry....I'll turn the typing speed pot down a bit..... ;D

Not on my account Dave.... these days I don't hurry unless I have to... :big: betcha Kermit is happy that somebody answered, let alone at what speed....

OK Kermit: get to work!

Joe

 

[Kermit]

I love this place ;D

Okay, so I've got the plan of attack, but nothing bigger than 5/8 in the stock pile yet. Hmm, I suppose I could do one in 1018...got tons of the stuff. At least it feels like it when I look through the pile for something..

Gonna sign off for tonight gentlemen, You have relived my mind of this enigma and now I'm feeling the hours.

More pics for you soon,
Kermit

Oh I think you hit that on the head!....Have a good night Joe!

Found a 4 inch piece of 1.5 inch tubing predrilled with a 1/4 inch hole. Perfect for a 5/16 -18 tap.

Thanks again for the hints and help,
Kermit

Just an update to my drawing to show how the rotor will be machined.

Have to wait for a 5/64 end mill with a 3/8 shank to arrive via FedEx first.

Alright!
Congratulations!
That didn't hurt a bit did it! ;D

You have passed a great milestone in lathe operation...pretty soon you will be staying up at night dreaming of all the things you can do with your rig....as new insight presents itself....I speak from experience... ;D :big:

Make sure your having fun Kermit....that's important.

Dave

 

[Kermit]

I'm always having fun, but sometimes I hurt to much to enjoy the fun.

Thank you for all the support and encouragement Steamer, and Joe d. I am in your debt.

So anyway, today is wednesday. Which is a 'raw material' order day. Should I get anything else with the order besides the endmill for making the slots in the rotor?

Let me know if you think of something I might need here,
Kermit

 

[bearcar1]

A goodly length of magnet wire? ;D

Got that. and if I need a different size I go to http://www.magnet4less.com/ specifically ; http://www.magnet4less.com/index.php?cPath=9_20&osCsid=cda5250325ef4dfc53ed2fe7e9e2446e

I may end up needing a different size than what I have. I haven't done any calculations on this little genny for voltage output.


How about anything for the lathe work I might have missed?

 

[Kermit]

I have the endmills now.

Whether I use it for this or not, I have ordered a slitting saw and arbour, as well. What I need to know from those experienced and willing to answer; is which one would you use? endmill or slotting saw.

Remember its a paper/epoxy material, not metal.


Hoping for more than one opinion,
Kermit

 

[steamer]

Drawing of part?
;D
Dave

 

[Kermit]

Hasn't everybody downloaded and studied every drawing pdf I've ever put in a topic?

I hope it looks as good as this one when I'm done.
Oh, and, the dimenisions for the slot are 1/8 inch wide and deep.

Kermit
