Yes I did. My math says 40nm if torque before she gives way. Ill get my neighbors torque wrench and wrench on em.
Instead of doing a set screw, you could use a small press fit pin going through the king pin, this way the bulk of shear will be handled by the steel, not the retaining compound
Already going to a machine shop tomorrow to sort this out. I have a ton of 3mm dowel pins I can stick in.
For those of you with BN hangers. Loctite and antiseize do the opposite of each other. Take your time and install cleanly and you wonât have to worry about issues. Small film of anti seize on the inside of the hanger and then bolts.
Clean the inner threads with alcohol and Q tips. Clean the bolt threads with alcohol.
Apply loc tite
Torque. I was hand tightening these to snug before and was coming up way looser than this and had no issues. I torqued to 50 inch pounds or about 4.2 ft lbs, about 5Nm.
Most of what Iâve found suggests around ± 10% 7Nm or 60 in-lb for m6 in aluminum for recommended, not max. But Iâm choosing to stay lower. Those values depend on number of factors

Why put the anti seize if youâre going to wipe away with the alcohol? Genuinely curious about this
He cleaned the inner threads with alcohol, not the hole itself. His way is the ideal, but of course I cannot rely on people being this careful, hense the fixed axles
Holy ChristâŠtorque wrench settings, Q-tip colonoscopy, dowels for KP? Too funny, theyâre skateboard trucks! How bout sticking w something that works and been proven to hold up, instead of âLook at how much math I know?â With all due respect, I donât want to be Good Will Hunting just to ride my skateboard to the liquor store. The engineering concepts are great and all, and real impressive and superior, and all that. How about some basic real world stuff too? Thereâs a reason trucks are designed the way they have been, for a while. I hope no one gets fucked up in the experimentâŠ
Nothing is stopping you from buying a set of Caliber 2âs riding them for 200 miles and then replacing them because the axles bent. Itâs traditional, and you can make it work for our application.
If you want peak performance, you have to go the extra mile. If you donât, I hear that the current crop of Chinese pre-builts are decent. They will definitely get you to the liquor store and back.
HahaâŠPeak performanceâŠlike what happened w my base plate, after a month? Too late, I already tried the peak performance/extra mile crap, and didnât make it very far. Over complicating a design, doesnât always equate to peak performance. Sometimes simple is better, and definitely better than glue, and screw in axles.
This is how you do this properly with shoulder bolts. @Boardnamics is not the only one to ever use shoulder bolts on a truck.
I suspect there are a large number of issues with these trucks that were caused by the user. Kevin has taken a lot of heat for the shoulder bolts- but theyâre a component that requires to be treated differently than a fixed axle. Some of the problems were from the bolts and his equipment. But if you want precision components, you need to treat them like precision components. If you want precision components that are reliable, stop looking at $40 budget hangers
And most of the people on fixed axles have been reusing the same nylon lock nut for 50 reinstalls. Fixed axles have advantages, the largest being that theyâre more idiot proof. Esk8 riders need to recognize that running speeds of 30mph for 100s if miles per year is not what these components were designed for. Inspect regularly, Install properly. Itâs not a fucking skateboard anymore, stop treating it like a toy
Shoulder bolts give you adjustable axle length. Fixed axles do not. If you donât need adjustable, get the fixed. If you do, install them properly.
You could treat the SR hangers very differently⊠you didnât have to go through this stuff.
I donât really see what would need treated differently?
I only added the Loctite once I had spacer and everything dialed it. Antiseize should be there on the SR too
Pressure seals
Torque wrenches
Antiseize
You dont need to worry about that stuff with SR hangers
Ah, i donât own any SR so just curious.
Steel and aluminum, small pocket. Thatâs potential for corrosion lock on anything right?
I just chose to use the torque wrench to see where my estimated tension was compared to a reasonable spec. Itâs not needed.
Pressure seal hasnât given me an issue
Planning on picking up some SR one of these days
Unfortunately
Yeah the seizing happens but not very frequently and I guess for different reasons here. I guess this is all solved with one basic fix so not much to discuss now that itâs all over.
SR has a new website
Yup. I wonât miss the shoulders
These are not my first trip down the precision road. I have raced slalom, downhill, etc, and have plenty of precision trucks. All of them from Donât Trip, Cindrich, and Ronin, have very little maintenance; and solid designs. Obviously, I wanted something more than Chinese turners. These just need a few adjustments, set axles (which Iâm getting), and a baseplate w a threaded KP, or ACTUALLY pressed.Take Ronin, threaded KP, that transitions to a twist/press w thread submerged below the flat of the baseplate, and chamfer the entry hole to prevent a stress riser. Ironically while just trying to take off my axle, it seized up. If you have to baby these things, and the KP comes loose so quickly, this design is not very effective. Only reason Iâm saying something, is hoping to avoid someone getting hurt. Enjoy em, if you like, but I ride pretty aggressiveâŠeven to get beer, and they arenât working for me atm.
is surfrodz hangers also aluminum? OR steel?
Alu 6061
Steel inserts for threads
