1949 O.K. CUB .074-----YAHOO !!!!!!!!!!!!!!

Thanks guys!

Yeah, it's WAY past time for me to be getting a good drill press...looking at a used one today. It it doesn't work out, I'll use my Magic Plastic and get a new one from Sears or Lowes later this afternoon.

It looks like I've finally got a free evening, and so, will review these suggestions on this little problem with the broken bolt. If it's assured that I CAN get a replacement crankshaft, I may venture ahead with an attempt to drill and remove it.

Guess I'm gonna re-join my local club also, since this is the second or third gift I've received from these good guys. With all the clubs and organizations I belong to, I may have to eventually file "Membership Bankruptcy" and apply for government aid ! (SERIOUSLY joking here !)

Anyway, bragging or crying, there WILL be a photo report following!

Kim:

What you are seeing here on this thread represents the finest in our forum; people helping people with alternative suggestions.

(There may be some that actually ENVY you in your predicament)

Good luck in your attempt to correct it.

A good friend just picked up a really nice table top mill machine, with a precise X Y axis table and all the clamp fixtures, endmills, flycutters, supports, ect. It also came with a box of Starrett measuring micrometers. I am jealous to say the least. He bought it off of Cragislist for about $400. The Starrett stuff is worth that alone. Take a peek there, you might find some deals.

Financial damage incurred thus-far by Kim's free OK Cub: $337.09

This figure DOES NOT reflect the added costs of possible Hernia Surgery resulting from the solo assembly of this engine's "Accessories" !



ALL RIGHT!!!!!!!!....Everybody Stand Back!!!!!!!!!!!!....SOMETHING's 'BOUT TO GET DRILLED !

Holy Schnikey's!!,,get after it!! lol.

yeah...but first, I got to go to work and start filling the crater this sucker made in my toy budget....oh well.......

Gentlemen,

On this fine and rainy morning in South East Missouri, I would like to present for your perusal and approval...one, fully-operational, 1951 OK Cub .074 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

In the words of Little Richard, "Wop bopaloobaa, balo bam boom !!!!"

Didn't have enough daylight to tach it, and don't care. My "Model Airplane Nerd Sense" tells me that it's got enough umph! to drag a "Q-Tee" around the hill...and that's all it's got to do to make me happy !!!!!!!!


[strike]

Sincerely,
Caffeine Overdosed Kim

P.S. And yes, I AM gonna clean it up !

A great big pat on the back for you Kim. have a pint and toast for your success
That thing looks like it would go great as a diesel.

Thanks Nitro!

Yep, while it might go as a diesel, this one's gonna be drinking glowfuel during it's time in my stable! Also, I joined your forum, using my .060 as credentials ! Looking forward to the discussion of these things!

In the meantime, got to build something for all of these noise-makers I'm accumulating !

Later!

Thanks for joining hopefully it will get rolling pretty soon.

AND IT LIVES!!,,Congrats Kim.

It looks like a drill and tap for the repair?

OK, don't just show us the pretty lady doing her thing. What did you have to do to get her all dressed up and running?

We want the whole skinny.

Sorry...feel like I jabber on here enough, and didn't want to wear out my welcome!

1. Woke up early (3:00am)...did my usual Folgers O.D. (don't laugh...this is a VERY important step!)

2. Bolted the Cub securely to a 1/4 aluminum plate, and wrapped everything in papertowel strips.

3 Carefully ground the end of the broken screw flat with my trusty Dremel.

4. Used the Dremel to grind myself a center punch from an old drill bit.

5. Took about 20 minutes to finally get the punch where I thought it was centered on the bolt, then hit the sucker.

6. Decided NOT to use my big, giant new drill press, and instead, put the Dremel in it's little press I've had for 30 years.

7. Got a pilot hole going, checking dept, then drilling then checking depth..ect. When it stopped easily throwing strips of metal, I stopped ,figuring I'd hit the hardened metal of the shaft.

8. Continued to re-drill, gradually increasing the bit sizes 'till I felt like I was pretty close to the threads all around.

9. When I was as close as I dared, I carefully started a 5-40 tapered tap down the hole, cleaning it after every 1/4 turn or so.

10. When it started fighting me, I already had more than a 1/4" of good threads, so I called it quits.

11. Cleaned it up, flushed the hole with alcohol, and put in a lock-tight coated 5-40 stud I cut from a cap screw.

12. Stuck a wooden 6-4 prop on it (wasn't sure what to use), and the thing startled me big-time by just cranking up! Think it just wanted some TLC !

Now, my problem is finding a project that needs to have holes drilled in it by a new drill press!

I have one for you.
Take an 8cc not stunt tank and make it into a jerobee tank

Kim:

Thanks for the "play by play" description of the Cub resurection.

With a stud now in place of screw you are good to go.

Good work! (In with running time the remaning screw fragment may come loose if that ever becomes a concern)

That's true wath the prop doesn't fly off one day.

True..there's always that risk...but considering that things do fly off my planes every once in a while anyway, the threat level is really not elevated that much!!

On the 8cc tank, I'd help if I thought I could, but to paraphrase "Bones" McCoy, "I'm a Lucky Redneck...Not a Machinist!"

No i was just giving you something to do with your new machine.
Or you could attempt to make a geared twin.

Nice work.

The tap "fighting you" might have been a hard spot in the metal or you bottomed out in your drilled hole. A good bottoming tap should have stopped up snug to your drilled hole. If you did use a bottoming tap, the interior bottom threads might be meak just due to the way the tap is cut. If you used a pointy end thru-tap, then you might have about 1/2 threads down in there.

Regardless of my speculation, good job. should be good to go with a carefull eye as you run it.

Folgers is a requirement,,that goes without saying,, .

Thanks! Yeah, I didn't have a bottoming tap in 5-40...guess I'll get one to throw in the drawer. Andrew has recently provided me with some new hardware sources, so...$$$$$$$$$$$$$$$$$$$$$$$$!
