Ah my bad just saw your Facebook post, I assumed it had a hex cap. Cool more shitty boardnamics parts. Sorry bout that
we had a whole discussion about this right?
Oh man. Iām a little nervous to run those now. I have a set sitting in a box and that may be where they live now. Thanks for bringing this to attention
Canāt you just use a hex headed bolt?
I donāt think its possible for it to come out while the nub of the hanger in the the pivot cup imo
Idk how tf you plan on riding your board
Wrongā¦I almost ate shit
Just to comment on this earlier response by @anubis : this is some serious commitment to the esk8 community in the EU. His website is great, the options are excellent and the prices look great too. Cheers . I can only hope his inventory grows ( and his workspace). EU guys should give him a shot with their business.
Another 25 miles on my BN hangers and no issues
I only tested them for two weeks, I have no affliction with Boardnamics. Just tested them and thatās it since Iām a neighbor of his. This is not something you should complain to me for, hope youāre ok though.
wheel sheeet
I spent all day riding these in Icy conditions enjoying the width and stability, did a bunch of 180 slides
Is the kingpin not a press tight fit? Adhesives irrelevant. The caliber kingpins come out too. And thereās no way for them to come out while youāre riding. Theyāre under tension
his complaint is there is no mechanical retention.
I think it needs just like a grub screw kinda fix
Iām not trying to be spiteful just a little bit confused
I swear I saw CAD pictures of adjustable baseplates with an actual kingpin at some point.
Just looked now and itās not?
Not looked at a fixed angle baseplate either
Is the implication that they fall out? Are they loosening? Whatās the tolerance measure to?
Thereās no detention on most stock Baseplates other than press fit. If it was anything less than that I would presume it would introduce wobble
Something was not done right when I assembled that one.
The math says that after 7 days of curing, the force required to take that pin out is 1900lbs.
The adhesive is loctite 680 retaining compound which is designed for this application. Itās also very vibration resistant. This is clearly an assembly error.
This is with data from this https://tdsna.henkel.com/americas/na/adhesives/hnauttds.nsf/web/461C42048B60E62C882571870000D86B/$File/680-EN.pdf
It is
The area is 531mm^2 and the compressive shear strength is 16N/mm^2 on aluminum. Thatās around 8400N or 1900lbs.
The clearance between the kingpin and the baseplate hole is very very close. I actually have to warm the baseplate up to around 50C to insert the kingpin. Looks like I didnāt put nearly any adhesive on that one.
Little surprised this happened when you rode because there should be little force trying to take the kingpin off when riding. The force is mainly on the hanger seat which travels through the bushings into the baseplate. Kingpins see lots of side forces.
I thought Iād do a service. Iām not sure whatās the confusion?
Wait⦠what? Just a post glued into a pocket? No head? Whatās the small hole?
Iād grub screw that into a notch on the shoulder personally. But the adhesive data supports it. I would be concerned with long term use
