[US] Precision DKP/TKP Trucks

I agree.
So the helicoils themself should be some sort of surface treated too. Otherwise you would have just the same problem.
Honestly I would just go with stainless steel bolts and anodized Aluminium. If super worried maybe some MoS2 lube?

This.

Anything that is likely to be overtightened (such as tightening down on bushings because they want them firmer) or removed a bunch of times (such as replacing bushing) shouldn’t be an aluminum thread imo.

Update: dropped the price on hangers and secondary pivot (see first post)

Whoa! i want one for BnM1 street gear drive.

Just wanted to say thanks for providing the CAD files @Razillian , it was a huge help in working on my college capstone project lol. Here’s to hoping it works out and i can actually manufacture this :stuck_out_tongue:

It’s a replacement baseplate mechanism designed to actively adjust the baseplate angle on the fly with a linear actuator so that you can get the best of both worlds between carving and stability, designed to be used with an IDEA deck and drop brackets. Next is to figure out the electronics and figure out how to code a controller to set it to a specified angle for a given speed from the telemetry data on a VESC lol.

Without the linear actuator, this design would make for a really nice adjustable baseplate/truck design.

Its actually way overengineered for that :joy:. The main baseplate core is supported on a custom cylindrical roller bearing, and as a result should allow for almost zero resistance adjustment. Also has hardstops at the ends of the travel range using M4 bolts, and precision machined rails for it to slide along with indexing between the two halves. If i wanted to, all i would have to do is redesign the core to have preset bolt holes instead of a slot to allow for locking it in place at preset angles haha.

Very impressive!

This looks nice on the computer.
How might that actually be manufactured at a reasonable cost?
Design for manufacture ability is, unfortunately, lacking in ME programs in the US. I spent about a year working with Clemson ME seniors while working with Cummins Turbo in South Carolina, and it made me sick. They were designing stuff that could not, realistically, be manufactured.

So i’ve actually consulted with the university machinist i have access to, in order to get feedback on the feasibility of production - The drop bracket is pre-existing (IDEA type 4), so i only need to lasercut the mounting plate for the actuator at the back, and lathe down some new spacers, which is simple. As for the baseplate, the rail that everything sits on is made in two halves which should be able to be done on a relatively simple 3 axis (with some fixturing). The baseplate core which sits on the rail should be able to be done mostly on a 3 axis with two fixturing setups for each side, and then two additional operations for the pivot cup hole, and kingpin bolt hole (although access to a 5 axis machine would make it significantly easier, with less specialized fixtures required). The cylindrical roller bearings are just 4mm steel pins, which can be done on a lathe, and the bearing cages will be resin printed.

So far, the feedback i’ve gotten from the local university machinist has been quite good, with just minor feedback on tolerancing and fixturing accomodations - I’m always happy to take input on if you have any advice though! Definitely not just trying to make an impossible component haha, i’ve been trying to watch videos on the machining process and taking into account limitations of the machines i have access to.

I’m absolutely not trying to me mean here whatsoever, but this is not overengineered, but rather, underengineered, honestly, :smiling_face_with_tear:
You can’t make this model, (and somewhat work well) as I’m seeing it, and any professor that gives that a thumbs up should be fired. Sorry bro.
Just giving my opinion as most should in the know here, like sketchy battery builds.

Hey kids.

I am on the midst of experimenting with these.

Has anyone ran them as TKP?

Did it work well?

What bushing combo did you use?

@glyphiks Al you ran these TKP but I think with different baseplates?

Isn’t it essentially a surf Rodz TKP? I would assume it would be fine (but I don’t own a set of the precision dkps)

I am not sure if the baseplates are identical.

Looks promising so far.

Looks like it should work

Seems legit.

I need to mess with the bushings, but I think the TKP set up is going to be good.

It’s really nimble!!!

I can confirm it is surf rodz TKP geometry. The DKP midplate is compatible with standard surf rodz TKP hangers, and savage1 TKP hangers.
