So I just got a new bike with the 1.5 headtube and I need to make some reducer cups. I don't want the extra height of the FSA ones and I'm not really down with the e13 internal style.
I did some measuring and I think I can make a cup that houses my king HS inside the 1.5 HT and still gives me a low stack height.
Somebody mentioned they saw pics of something like this on hcor. Searching revealed no pics.
Anyone.

I'm running a FSA Zero Stack reducer headset that'll do the job with minimal stack height (much less than a normal headset). Check those out.

this is what I was thinking. Once I figure out what stack height I want, I can bore the hole to that depth.
This part will weigh 53 grams. Plus a king HS and you are sill the same weight as the lightest reducer HS.

I wonder if you can get dimensions and tolerances for the O.D. from the 1.5 standard website, if it's still around? Then you can just measure your king for the I.D. Was it www.onepointfivestandard.com? Seems like a pretty straight forward lathe job, at least for someone who's a good machinist (i.e. not me).

Just checked, there are some drawings on the 1.5 standard website that may be useful. In fact, if you actually need someone to do it, I'll draw it up in AutoCAD for you, but it'll be 2d.

eps???
Why would I have it in eps?
Engineers don't use Illustrator
I'm an engineer and I just used MS Paint to finish a schematic for the board members :thumb:

If you're inserting King cups inside,why don't you make a reducer based on just the King bearings themselves?

I'm using an FSA Orbit Extreme Pro 1.5-1 1/8 HS. Works very well so far,light low,bearings have 5 year warranty i think.

I figured the simply ID bore would be much easier to machine. I might look into it more though.

That was my other option but I have a hard time spending that much on a headset that doesn't say King on it.
I also already have the King.

I often export to illustrator to post pics of drawing's on the web. "Preview" or most other basic programs can open .eps files easily...

Simple and effective, looks good. I like the idea of different depths to alter the headangle.

What program do you guys normally run for lathe/CAD drawings? I'm using ProDesktop, 8.0 I believe. It runs quite nicely, and is fun just to mess around on. I'd like to get Rhyno 3D, anyone have experience with it?

We use Rhnyo a lot but not for cad stuff, just 3d design. Mostly rendering for client presentation. It doesn't have enough info for accurate engineering stuff.
For model generation, we use Solidworks. It takes longer than Rhyno, but the model has a lot more data in it.
For CAM, I use Mastercam. Solidworks integrates with Mastercam seamlessly.

My lathe is conventional, so I don't need to program it.
My mill is CNC though.

see if you can get your hands ona king perdido (sp??), and base the cups around that headset....would be very cool!

Ah,
Sweet. I'm a sophomore in high school, so i'm still using the conventional programs. I can't wait to use a bit more advanced program. ProDesktop is fine for creating, but so-so on rendering. It tends to be a bit harder to combine complex shapes, say frame tubing for example, but is still quite useful. I designed a pretty sweet model of a Shiver, but it's hard to get the smaller angles, like the dropouts, to render correctly.

^King never made the perdido to my knowledge...


I just use autocad to draw simple blue prints mostly for fabrication of roll-cages and the like. I am not an engineer by any means, but I like precise measurements.

Actually, they did make the Perdido, but it was never available aftermarket - only OEM.

a friend of mine did just what you want to do, not with a king though, but it worked, its on a dh bike, buddy is really fast, and its holding up fine.

Someone mentiones Sgt Brown from honda turner may have had one of these. I remember the pics, but dont recal what to search for.
Is this it?

I would just buy some evil cups, fsa headset and then if your not happy just replace the fsa bearings with some SKF jobbies, then sell the king.

Hey Cave Dweller, I think I met you down in Inner City Cycles once, I'm one of Russ' mates, did you ever try getting those dorados wrapped in another layer of carbon to repair them? Tell Russ to get his head out of his ass and send me an email with his bike project will you?
Cheers.
