I put together a quick video to give everyone an idea of how the steering is coming together. As I've indicated I still have alot of work to do yet. But here is a little peek, enjoy..


WOW

Thanks for the video. Looking great. Regarding the linear bearings, impact of shock loading/shaft deflection if any and alignment issues if any with overall front end wear, i.e. Rod ends, ball joints, A-arm ends?
Also debris impact on the bearings, wear and tear on the shaft from rocks etc during routine use?
Thank you.


GO, your welcome!
So, I've briefly given some specs of the components in a previous post but here's a quick run down:
the linear bearings are rated at 2800 ft/lb side load capacity with 5% mis-alignment capability. The shaft, center plate, tie rods and all the components are so over rated, I'm curious as to where the first failure will actually occur. When I fabricate items I do not for a second believe I won't have issues, I take a path of looking at my own and others experiences and building to those strengths and weaknesses. The reason I did not use the sweet manufacturing rack and pinion I discussed in earlier posts was the lack of sufficient side load capability.

There is so much to finish on the steering assembly. What is shown is more or less as named, a proof of concept. I have no way of knowing if it will work or be a miserable failure. I'm confident it will work, however how can I say what challenges lie ahead. If I was using the factory oddy or pilot steering set up and was riding and had a problem, I would fix it. I have the same mind set about all of the work I've done to the buggy, If I break a part I'll fix it. I will be adding seals to the shaft and most likely dust boots. The center mechanism will have delrin wear plates and stainless cap plates capturing the bearing. In addition I am fabbing a 1/4' thick aluminum skid plate for under neath the front end. Think of a shock for a moment. A shaft that experiences constant motion, riding threw a seal while being exposed to the elements at all times, yet unless there is a catastrophic event, the shock keeps doing its job. What I'm saying is, I engineer around those things that can be quantified and also imagined and the rest...I just hold on tight.
When setting out to do this I just knew I wanted to try something different and I have, I try not to say what if so many times I become catatonic and immobile and build nothing. If this set-up doesn't work how I'm picturing it, everyone can believe I will be back at it with my next idea...I have way to many of them to stop now!!

I'm not sure if this helps with your question, but if things wear they should be replaced. Every component on the front suspension and steering can and should be replaced if it wears so much it no longer functions as intended. I have yet to find one thing in life (other then my wife...you know for putting up with me) that is perfect.

Thank you for the info, much respect.
Regarding the shock comparison, I don't know if or how often a shock is placed in said location and cycled during fitment and testing and thought to properly setup but possibly in application the shock may be binding. The shock if it's not cycling correctly 100% of the time may never be known. The rack of the flip side will have entirely different results, (I know, I'm master of the obvious).
That said, I look forward to each update and developments. Keep them coming, I love to see the changes.
I've been reading about the different linear bearing options, if you don't have it "right", the answer is, as you said, definitely out there.
Regards.

I also wanna say, I have mad respect for the members on this board. The collective knowledge is mind numbing.

In regard to the shock analogy, I was more comparing the manner in which most shafts are left uncovered and yet remain damage free. The question of a rock hitting the shaft has come up many times, the shaft will have dust boots, just as a regular rack and pinion does. I guess I look at it this way, if I hit something hard enough to damage the rack bar with a skid plate in place and boots over the exposed areas, I'm thinking damage is gonna happen no matter what precautions are in place, absent riding the buggy.

The linear bearing...well I'm not sure I've seen a similar set up to compare it to. I guess once I beat the hell out of this thing, we will get our answer!!! I am definitely itching to drive it.

Yes I have to agree.
I think Hoser was first to recognized this when he was thinking of the the "brain power" tab.
Not to many dumb dumbs on this site but it seems we only have about 70 or so regulars here. Those regulars seem to be sharp. It's to bad we couldn't just take this group and put them in one factory. I think the product we make would be a run away success. In my life I have worked with some very smart guys in maintenance and management. I have unfortunately also worked for some real goofs and retards, so I just quit. Some of the companies just don't realize what they have done, manager just to stupid, yet that clown runs the show. It has happened twice in my career. One company went bankrupt after the whole crew quit. I do have a nasty habit of quitting jobs just because something sexier came along but I have only quit in anger twice.

So, I'm not sure whats going on in the world, but we are so busy at work, I have my guys on mad overtime. Which means I'm there twice as long...Ha and the jokes on me I'm salaried.. Oh well, no complaints. Except it's been cutting into buggy time. Thought I'd share a few more pics to shown alittle of the direction the steering is heading. Pictured are the outer rack boots, an example of one of the inner polyurethane inner seals, and the capture plates/delrine slide plates for the center bearing. Remember there will be an aluminum skid plate under the center and a flexible rubber seal around the center mechanism so no dirt can get in. Not sure I have much more in me then that at this point. I have about 70 hours in the steering between design and fab, and it's not done. Also, still need to in stall the electric power steering and weld everything up. Maybe this weekend. I guess time will tell.

Well, It's been some time since I posted anything about this build, hasn't it... I have been crazy busy...I know we all say that phrase way to often, but really I've been WAY to busy.. No complaints, it's just a constant challenge to keep balance in all the activities I so enjoy.

Anyway, how about a couple pics to show the progress I've made. In all reality these pics are a little dated a this point. The front end parts have been stripped off and sent to the powder coater, and the frame has been painted. I'm working to finish all the little details that when done right seem to take a life time. Also....no the inner rack boots are not on in the pics... Nor is the aluminum bottom skid plate or bumper....remember, in process pics!

Here are pics of the bottom steering set up, the plastics trimmed around the power steering, the new master cylinder set-up and new longer cables. I will say I have started building several very different FL350 based engines for this buggy...very different. I have various parts out with individuals who are supposed to be the best in the game when it comes to 2 stroke work, I guess I'll see.

I do like the new front master cylinder set up. It looks like the Jwhill set up :-) .
Thought about converting mine like Jwhill did.

I used Rear master cylinders from a Polaris Sportsman 500. I think they were $14.00 delivered. Everything fits nicely under the foot tub and the set up is protected by the frame and skid plate. I mounted the actual reservoir in the factory location. I got the idea from the jwhill post and from Dmoney saying search for REAR master cylinders.

Excellent work so far Sir! :-)

I would love to see someone come up with a master cylinder setup that us guys with no fab tools could use as a bolt on unit. One of the the worst designed parts of the Ody was the master cylinder system. It is a pain in the ass to bleed and it doesn't have enough piston travel to efficiently work the front brakes.

I'm sure others beside myself would like to see this!

i never thought of mounting the brake masters like that..i have the same set up on my fl450, which still isnt finished lol..but i like what you have done there...and makes it a lot easier to to mount some power steering

Fully, I had considered many different ways to set the master cylinders up. In the end, I wanted to maintain the oddy steering wheel so that drove the design. I stared at things for hours. I bought raw supplies to make brake cables and went at it. I haven't ridden it yet, but that will be very soon, come on powder coater. I'm anxious to see how the brakes perform. I will be installing the rear disc brake set up I have(a caliper and disc on each side) once the front is completely assembled. If the brakes aren't 100 times better then they were, it's back to the drawing board.

can i ask how you made your own cables...i would love to do powers steering someday, with a rack and pinion like that, but couldn't figure out what to do about the brakes

There are many companies online that sell individual cable components. If you do a search for something like, motorcycle brake cable parts, you'll find the companies. I used a place called "Venhill". It takes a little looking a round to figure out what you need, but these places sell it all. I purchased the same thickness inner rope that the factory uses, Teflon lined outer conduit along with conduit ends and cable ends. There are a plethora of videos online on how to properly make cables, some of them are pretty good.

Well, I thought I'd throw up one last set of build/assembly pics, before I put the ride video up.

I've come to accept that making and posting videos takes way to much time...HAHA.. Anyway, it's a quick one. Notice how quick the buggy turns...It's crazy, the chassis is way stiffer and I'm very happy. Still have a few odds and ends to do.
