Harley Davidson Machine Shop, 1953 K Model Project Begins

[@mudnducs]

Like the explanation for using 3 hold down points AND the use of paper on the table. Nice job !

[@DonDyarprecision]

Hello, I will show more of that coming up!

[@ypaulbrown]

Don, thanks for inviting us into your shop tonight, always a great learning experience…PB

[@DonDyarprecision]

Thanks Paul!

[@constantinehatzis2807]

Very satisfying work. Thanks.

[@DonDyarprecision]

Thank you too!

[@redshovelhead77]

Don, thanks for sharing what you have learned. You set a great example of how to mentor. Its important to make sure the skills survive.

[@DonDyarprecision]

The owner of the practical machinist forum had his main forum clown slander me as a dope addict, criminal, not qualified, I corrupt youth. The owner of that forum allegedly smells like spoiled hamburger, eats maggot infested chicken, a short fat Southern Racist leader they call "Stink Finger". Thanks for the encouragement!

[@dennisclapp7527]

Thanks Don. You make it look easy.

[@DonDyarprecision]

I really do not find this hard, but I have decades of experience with this model line, I even bought a new one in 1977.

[@Randysshop]

Looking good Don. That is always how it goes machining some parts. Thanks

[@DonDyarprecision]

Yes, working on old broken things, set up takes the most time, thanks!

[@ypaulbrown]

Fantastic Don….cheers my friend, Paulie Brown

[@DonDyarprecision]

Glad you like this little diversion in mechanics!

[@emerycreek8016]

You've really turned that old mill into a slick running unit! Thanks for mentoring all of us!

[@DonDyarprecision]

Me, the unlikely mentor with a bad voice and attitude, I have to think about that. The US fake internet machinist industrial complex claims I am corrupting youth!

[@warrenjones744]

Paper shims are cool, I have some plastic shim stock I like for doing things like that. Paper is not slippery though. I think I learned something here. Cheers

[@DonDyarprecision]

I lost sound on a portion of the video, I will better demonstrate the use of paper on the next video, thanks!

[@jamestregler1584]

Reminds me of my old 65 XLCH that dropped the transmission at the drag strip 🥺 The underside of the case looked like Frankenstein welded it up 😇 Campy the H-D man at old New Orleans Harley 😎

[@DonDyarprecision]

Hi Campy, the main problem pointed out at the factory was the 50% gear contact on 2nd and 3rd gears.

[@jamestregler1584]

@DonDyarprecision Terribly sorry was referring to the Ace mechanic Campy at Harley Davidson of New Orleans circa 1986 . After building the Sportster motor I asked Campy how can I reduce the 12: 1 compression '' Go steal a stop sign and make base plates for the cylinders '' 🤣 !

My repairs don't look like Frankenstein did it. 🤔 Uncle Fester mabee. 😁

[@RalfyCustoms]

Happy days Don, nicely done, buddy. I only just noticed those outer cover holes are plugged. Are they next on the agenda? Thanks for sharing and best wishes to you and yours Ralfy

[@DonDyarprecision]

The outer cover screw holes were not drilled at the factory except 2. The cover is aluminum and held with only 3 screws but they obviously were going to use the tin primary cover at a later point. I just might go ahead and drill those holes so that option is available if I cant get the aluminum cover to seal with only 3 screws right down the center holding it on.

[@RalfyCustoms]

​@DonDyarprecision I have the tin primary on my Shovelhead, not the same obviously, but same era I think?

[@toddk.5873]

It looks like the bosses are casted for the 58 - 69 primary cover. I remember an old timer years ago had his aircraft / motorcycle weldor friend build up the bosses with weld & he layed it out & drilled & tapped the holes for the late model cover on a Bridgeport. I was impressed. Now I'm wondering why he had the bosses built up if they're already there. I thought he said it was a 57 case with only 2 bolts.

[@DonDyarprecision]

I have the K model and XL parts books, I will take a look.

My brief time in a machine shop. I would see guys take the wingnut on the clamps & break out the vice grips. 😖

[@DonDyarprecision]

That would be a bad mix, thanks!

[@Mr39knuck]

I guess if you did not have a machine shop you could lap that on a piece of plate glass with some compound. What’s your opinion on that? Thanks I enjoy watching you work .

[@DonDyarprecision]

Hi, this one has too much warp, it has to be cut in a machine, thanks for tuning in.
