PM austin and see if he can give you more space. In light of what your doing im sure he will take care of you.

Jack, It might be better to put them in the "downloads"section of the site as I believe it allows more room for files.

Isn't that what he said he was doing?

 

[ozzie46]

No, he posted them in the "Plans" section of the forum in a thread under "Jacks Knucklehead Plans"( FREE)

Gotcha! I mis-read the post.

 

[Vietti]

Are these plans still available and if so how does one get a copy? Don't have to be free.

Anyone built one or posted a video?

Thanks, John

Looks like an American motorcycle V-twin circe 1950s? - Maybe "Hardly Ableto", or Indian? I thought "knucklehead" was American slang for someone who thought with his fists? But I'm a Brit, so know nothing of these things...

Maybe I've lived a sheltered life (as an American) but the only times I've ever heard the term knucklehead, it was either an insult, like calling someone an idiot, or a specific Harley Davidson engine.

The engine @Felix attached seems to resemble a knucklehead in some ways, but not all. I'm not sure it is one.

But the only thing I know less about than car engines is motorcycle engines.

The engine shown is a flathead, the knuckle head was overhead valves. There is tons of info out there on Harleys. I'd like to see abook devoted just to their engine designs, no electric versions!

Jack, depending on what software you have for creating/editing PDF's, you can try using "Reduce File Size." I use Bluebeam Revu and have been able to easily get a 50%+ file size reduction with minimal degradation in quality (I like to embed photos in some of my drawings to make the assembly easier to visualize, but they can really bump up the file size).

I am new,do you know what is it?

That is a Flathead, I have been working on plans for the 45 Flathead,

Try installing Drop Box, and download the Knucklehead Files there, file size is not a problem.

 

[ChazzC]

Thanks; I have Dropbox, but a lot of people (and companies) don't either like using it or don't allow its use. Reducing the file size generally works for everyone.


Thanks again,


Charlie

I've learned more about the HD engine today than I knew before. Until today, all I knew was that I saw a guy who made a model once, so I knew the name. I have no idea if that model is worth buying.

I would be interested in downloading that set of flathead drawings. Send me a message and I will provide you my personal email and you can send them to me directly. Thanks for your consideration. I also see that the original thread was from 2014 (?)

Hi guys, I’ve been riding Harleys for 30 years, I have a replica engines 1/5 scale knuckle head engine , see pic and they are great little runners. Does anyone have the flathead (sidevalve) engine drawings at all? I’d love to have a go a building one. Thank you.

So what is the reasoning behind a Harley D side-valve engine being a knucklehead, and the insult? Or are the riders called Knuckle-heads, or the cylinder heads held on by some Knuckle device? Google tells me it means idiot, or half-wit. - So that suggests the engine was designed by an idiot, or preferred by half-wits, or something? Or maybe it just means it was a very simple engine?? Anyone know?

The Knucklehead has those 2 exposed rocker bolts / nuts on top looking like knuckles on a fist . The Knuckle head was also Harley's first production overhead valve engine .
