Confirmed with BKB, 50deg on both trucks.
I will try to get back here later today, under the gun here right now…
Heya Brad, I’m looking for a bushing set up that can do well on turning radius, mainly for track racing.
44" dropdown deck
270mm Kahua trucks
Caliber II 50 deg baseplates
155mm pneumatic wheels
Weight : 70kg
@RipTideSports The Caliber 2 cups i ordered are smaller than the stock one that came with my caliber 2 truck, is that normal?
Additionally mine don’t seem to fit.
the stock one is 17.5mm
yours are ~18mm
The pivot on the truck is also about 17.5ish mm
Edit: The pivot cups seems to fit on my other baseplates, just not the one i have installed.
The cup wiggles on the axle (also not sure if it’s normal to a certain extent)
We make our pivots with an interference fit into the base plate so they are a larger diameter than stock. as for the pivot nose on your hanger, it appears you have had metal to metal contact which may have reduced the diameter of the hanger’s pivot nose. Since our diameter is larger than stock, when installed, the inside diameter of the pivot shrinks making it tighter on the pivot nose than it would be uninstalled but your pivot nose looks shot. Can you measure it’s diameter?
Hey,
thanks for the explanation. I can’t imagine how it could’ve had metal to metal contact to be honest, the pivot cup covered everything up i think(will test fit again later.)
Haven’t eaten through a pivot cup yet. It does look weird yes.
The diameter is around 12.50ish.
I tested it with a new/ semi new (?) hanger too and it had the same slop which you explained how it came to be and how it will be fixed.
same 12.50 ish diameter, depending on where i measure.
So the pivot cups fit on 2 of 3 tested baseplates.
On the one i have installed i can’t even get it 1mm in.
i still have 2 more to test. Will report the results
Interesting, my Caliber II pivot noses measure 12.83mm in diameter
On both sides? One side is bigger since it has a seam.
i measured the non seam side
I am measuring the non seam diameter. On mine, the seam is the smallest diameter it is 12.45mm, everywhere else it is 12.8mm average
i can fit your cups on 4 of 6 baseplates
The ones not fitting are my stock Cal. 2 front truck and the caliber 2 baseplate i have in the back.
Front is 50deg and back also i think.
Install them in the base plates to confirm looseness. Best to have them mounted to a deck to install the pivots so you have enough leverage. I take a flat file between the kingpin and the pivot and use that to rock the pivot back and forth as I force it into the hole. I takes some doing sometimes.
You might have a set drilled just before the drill bit went out of tolerance so the hole is undersized
Cast stuff has horrible tolerances xD
I had a lot of caliber baseplates, both 44 and 50 degree, all with riptide pivots that fit perfectly.
Maybe bad luck again?
Thank you, that wide tolerance is why we need to make them hard to install unfortunately.
lol it’s still in his name
I just got some for my cal 2 cast baseplates and they were tough to get in but they did go in just fine, no slop on the hanger
Technically 2 baseplates from possibly different productions. I didn’t buy the rear one, i got it from someone.
Shall i still try to press them into the non fitting baseplates with all force or skip them?
What else
I noticed the other day that what I think are torqueboards caliber clone trucks have a different pivot cup than regular calibers.
I can grab pics l8er
like you described the riptide cup is super loose, I’ll try measuring them too.
This is how far i get it in my front baseplate
Update: after using a pipe wrench it slipped in completely
Before pushing the cups in i made sure to drill a hole in the baseplate to A: make it easier for the air to escape and B: being able to poke something through to push it out.
Idea stolen from Bioboards cnc baseplate
