Rob if front of your car hit something does steering column collapse under impact or, either stay solid? It is better to lost steering control in collision rather than have hole in your chest.

[@alr7879]

Much respect to apex' manufacturing skills! But rather mouting the steering rack to the periphery of the engine, I would have welded a seperate bracket on to the chassis, guiding the rack. Less movement in steering, more durable. Doesn't take much time to rattle this connection into pieces, no matter wich material. Greetings from Germany! Keep it up, glad to see any entertaining rotormodifications on this level!

[@BJK1715]

[@wheeln24-79]

I don't know why he's wasting his time with that engine mock up stand. He's mocking everything up in the car in this video like he should be. But yeah anyone can see that it needs more bracing. I wouldn't put 50 grand on it.

[@CaseyFinSF]

I mentioned the same exact thing in the last upload he did when building it. He said he would be able to dyno the engine before putting it in the chassis, but not without a better cross braced stand that could take all that torque he won't....

They are becoming expensive, however mazda3, Volvo v70, and an Astra all have cheap electric PS pumps, that may be used. My 13B is manual steering for now, until I either find an MR2 pump that's not $700 or figure the wiring for one of the others.

[@nhcs2k]

After a lot of very good videos in this 4-rotor built-series, this one was one of the best so far. The more parts come together, the more exciting it gets.

[@chakadog100]

As much as I enjoy watching other youtube builders that just slap shit together and send it because it makes for more exciting content in certain ways, I can relate more to Robs process. He is extremely passionate and thorough with his build! It makes sense considering he isn't just making some throw away Honda, or LS swapping something. This freakin' car and engine is a work of art! Cant wait to see it done!

[@Brother2Jis_27s4]

The steering shaft needs similar in and out working angles. The u joints will bind if ones like 10 degrees and the other is 40. If you can get them near equal it'll alleviate the tight loose tight loose feeling you're getting look up steering shaft angles and drive shaft joint working angles... it'll save breaking the joints when you add hydraulic assist

[@ryanbalkissoon]

This thing is gonna be insane. I love how much passion you have for this build, the attention to detail will show in the final assembly because it shows in conception.

[@emmanuelgomez6759]

Even though its taking years to build this is by far the most exciting build in KZbin in my eyes hands down!!!

[@fascistpedant758]

That steering shaft is super sketchy. Maybe you could mount an angled gearbox at the rack and run the shaft straight to it. Don't mount it to the engine. A collapsible shaft would be safer, if you don't want to get it through the chest in a collision.

[@einzelmotorsport6711]

Its the worst imagineable steering shaft setup I've ever seen. And with alternator & pump there , no real solution either

[@kirstysinclair9021]

Every vibration is coming through that wheel . Clueless .

[@einzelmotorsport6711]

Derek Robinson you mean servo? No physical connection between the wheel and rack? In Europe not even allowed, and certainly a huge risk to take . Simply think of stuff beforehand .

[@einzelmotorsport6711]

Derek Robinson yes I know, I build race cars for a living and we even retail out own EHPS pump specific for drift. However how does that help with the incorrect steering shaft routing ?

[@einzelmotorsport6711]

[@justinbelshe]

Slick looking parts! I've had to make due with hammers and files and torches...

[@harrisonwalker615]

Its coming along! Im no engineer but I have a couple thoughts. I was wondering if you could tilt the steering rack back at all to achieve a better input angle. Redoing the mounts for the rack would be a pain but possibly worth it. I think that heim joint support is a good idea for the space but It may send more engine vibrations throught to the steering wheel which may fatigue your hands on long drives. Even though the engine will be hard mounted it may reduce the vibrations by mounting the support to the chassis, if there is even room. It may also make it so you have to remove the steering shaft to service components. Let me know what you think.

[@willjunkin732]

NOOOOOOOO! Why did it have to end. I could watch you build this car for hrs. Wish I was there and able to lend a hand in build that beautiful piece of art work. Keep up the great work. 👍👍🤘🤘

[@Dori21ha]

Rob for your steering pump you may use Watermanracing Oil Pump / Power Steering Adapter with Drive Cable. It may fit.

[@andrewsengstock6016]

Seperate the U-joints further apart to reduce the sharp angle, I’m thinking by having a small shaft in between may help with the knot in the steering if your next option doesn’t help? I would say put the first u joint as close to the support knuckle that you’s made out of composite and then have the shaft in the middle running on an angle to the front left of the chassis, I also think by making the steering shaft a little shorter may help reduce the angle?

[@Gusrango]

My friend good video. I hope to see the beautiful engine running. Why not move the alternator the right side. Also can use electric steering wheel.

[@jakeeclouse4799]

Dude that tube versus pipe description killed me. Was not expecting that. Too funny. 🤣

[@gordowg1wg145]

Use a shorter/shortened shaft to move the top U/J close to the rod end/shaft support - this will have two benefits from the better joint geometry, ligher and more consistent steering and reduced stress on the components. Don't forget to 'phase' the joints as you would a driveshaft to reduce the variations in output speed and torque - hooke joints are NOT CVs. As I mentioned in a previous video's comments - I would SERIOUSLY look at rotating the steering rack to impove the pinion angle, if possible.

9:15, when you test the steering, the engine moves independently from the chassis like the grip from the tyres while stationary is flexing the frame thats alot of flex, im worried the trellis frame aint stiff enough and this beauty aint gonna survive its first high speed corner with grippy rubber on i know shit tho so im probably wrong just an observatoin, through beer eyes
