your dh setup

[rodgon]

yeah thats what i thought... but im no physics major...

so there is no such thing as a 35* bear?!!! ive been running a 52 in teh back all this time??? wow...

[SgtSparkles]

Are you using wedges for your bear truck because I don't recall landy making a 35* baseplate for bears just 42 and 52.

you are sorta right the make an 852 which is 8mm axle with a 52deg plate and 5 deg offest in the hanger
they also make an 840 with a 8 mm axle and a 40 deg base plate so when flipped its 35 deg...in theory

I am pretty sure flipping the hangar does not change the angle, just lowers it.

[SgtSparkles]

according to landy there is a 5deg offset to the hanger...imo it just changes the application of leverage on the hanger, but nobody has actually proved if it changes the angle as landy says it does

I'm sure it does, unflipped I felt wobbly at 12 mph, flipped i was stable all the way up to 45 ish.

[rodgon]

so no 35* baseplate for bears...

ill have to contact Scott if this is true...

please read thoroughly...its honestly annoying how often this is an issue

[TheJabberwocky]

my dh setup is a flat board with a bit too much flex for comfort... its a topmount that I made as a test of a ghetto press, with paris 180's and otang 4pres'

its.... interesting going past 40

If somebody just looks at the way the truck works, then they can see that flipping a grizzly hangar does indeed change the angle.

When hangars and baseplate interact, the hangar pivots according not the the angle of the base plate (although pretty much every time it is according to the baseplate angle, except if you're using bear hangars) but the angle that the hangar is sticking out of the pivot.

The angle that the hangar sticks out of the pivot is called the caster angle. And the caster angle is what really matters because it is the angle at which the hangar pivots around.

Here's a diagram of a hangar with the bushing seat inline with the pivot axis.

See how since the bushing seat is inline with the pivot cup, the hangar pivots around the same axis that the base plate is set at.

Now here's a bear hangar, or any other hangar with an offset bushing seat.


Kind of crappy drawings, but you get the picture.

In the second one, due to the recessed bushing seat, it lifts up the whole hangar, changing the angle at which it comes out of the pivot cup. Thus pivoting around 57* instead of the 52* that the baseplate is set at.

Then, when you flip the hangar, instead of lifting the hangar, the bushing seat lowers the hangar, thus lowering the pivot angle down to 47*.

on the subject of caster angle, does flipping a paris hanger change the caster angle? in my observation it does, but i've been told it doesn't.

[Shiyuchi]

The paris hangar bushing seat is offset, but it's not angled, so when you flip it, the bushing won't fit right, normally what you would do is shimmy it up so the bushing sits flat, but then you're at the same angle as if you never flipped it.

TL;DR: Don't flip paris hangars.

[bemmons1222]

really? i flipped mine to see what it looked like and the bushing seemed to fit alright. not perfect, but pretty well.

from my experience, paris hangers work marvelously flipped. the bushing has no problem fitting correctly, from khiros to jimzs to venoms.

I think that one quote from bpz has been floating around for a long time, without 99% of people actually trying.

FROM SOMEONE WHO HAS KAHALANIS:
I have tried flipping the kingpin, and have taken more aluminum off my trucks by trying to fit the kingpin in reverse than riding them tons of miles and hours with the kingpin in normally. After extensive riding, the tolerances are still very tight. Flipping the kingpin seems to tear up your bushings more than anything else.

Truth. Flipping the hanger does change the angle and how the tuck responses.

thanks colton, i think i would agree. paris trucks have become my all time favorite for sure. better than randal, bear, crail, indies, or gullwing IMO. although i still do enjoy a good ol' set of randal 180's and all those other trucks have strong points as well, but paris just blow them all away in my book.

All good stuff you need to try Stims

i've tried stims, jimz, old venoms, new venoms, pumkins, basically most bushings out there... this is what works for me

That's what I have read somewhere else. If you flip the kingpin since its harder than the aluminum of the truck the kingpin tears up the baseplate. I havent really heard of to many problems with the kingpin hole ovuling, and I can only remember seeing one picture of them flipped, and that was bpz.

in regards to flipping kingpins on Kahas, I've tried, and it seems like it would require me to sand out the inside of baseplates' kingpin hole if i wanted to run them flipped....

perhaps i just need to find me some metric grade 8 bolts and those would fit?

just sand down the edges of two parallel sides on the kingpin head
and as far as flipping the kingpin to everyone else--->DO IT. the threaded part is what tears up your baseplate. i'd rather have torn up bushings than a wobbly kingpin. and BPizz is the one who told me to flip them in the first place.

take out king pin,get 200 grit emory cloth,cut inch width about 3 inches long,wrap the cloth around the non threaded part of the king pin.
put the bolt head in your skate tool and spin around checking to see if it fits smoothly every few turns or so.
took me about 50-60 spins per pin ,cleaned them off,they slid in perfect fit with no play .
took about 10 minutes.
