Anyone have any info/drawings for CKAS T5 platform

Hello,

As title above says.

I have the manual from their website but the drawings on there arent much help!

Things like motor arm length etc?

Trying to gather enough information as possible before i go welding steel together aimlessly!

My email is mitchellmoxon@gmail.com if anyone has anything

Many thanks

Hi Mitch,
The CKAS info I sent was of no use to you???? -
I found that even if I had the exact measurements of the CKAS, they would be inaccurate, for my platform. UNLESS you're going to buy the very expensive SewEurodrive motor/gearheads. With my gearheads and motors, I will have to calculate motor arm length, rod lengths to top platform etc. - and I'm having fun doing those calculations. I "did" use the CKAS plans for my sizing of platform.
As you know, I just kept putting it off due to my ignorance in electronics, but now that I'm started, the creative juices are flowing. Before starting, I was just stressed by being afraid of making a mistake - but again, once started, WOW, the ol' head is working again.
Just go for it friend. You can build your steel platform - and when you decide on the motors/gearheads that you're going to use, get them, place them on the base platform - AND go from there for arm lengths and rod lengths. Please don't wait...just Get'er'done.
Have a blessed one.

Tom, full steam ahead approach!

I do plan to buy the SEW eurodrive unit so I could just use the original dimensions, however if I know where the rod is connected to the platform I could calculate motor arm length based on the degree of pitch and roll they use.

Hi Mitch,
GOOD..
First, how much are you having to pay for the SewEurodrives??? - Here in US - it was appx. 900 each for the 3/4 hp version...(think? the ratio was 30 and output was about 14rpm) - and they would have to be shipped from across the pond - AND my motor
guy here said (and I checked it out) - there are no service centers in the US for Sew??? That did it for me.

I'm sure you've read here that several have stated the CKAS was a flop, due to speed and degree of movement...
I am going to use 4" arms that will give me more degree of motion and once those are on gearhead, I will have to measure to top frame and cut my rods to match - after measuring for the pivot ends.

Mitch, for me, I would not try to replicate the CKAS exactly..."me thinks" and maybe more experience folks here, - well, you would be leaving a lot on the table.

Stay in touch.

Ckas units are not properly setup and have to use 240v motors over come bad design, of which sort of works.
Should we ask why you want a ckas copy? As @cthiggin says, best to design your own which will mover better.
If you do post a new thread and throw ideas around, yes the more experienced here can suggest and point you in the right direction.

bsft, and all.
As I stated in my build thread, when I started looking at building a sim, 3+ years ago, I was strictly a flight simmer, and at that time, CKAS was the only thing I could come up with that I felt I could build.
After purchasing all the necessary hardware, well, that's what me is stuck with, but with all of your help, we will make it as good as it can be.
IF I were just starting out (and into racing sims as I am now), I would go a different route.
Thanks

If you want flight, and IF you were starting out, then yes,I suggest building one of these, better balanced, easy to move even with wipers, good angle http://www.acesim.com/plans.html
no its not me in the video, but you can see the degree of movement possible.

Bsft,
Geeze - to darn ugly to sit in - that would take away from flight - I intend mine to be good looking and feel good getting into it. May not work worth a crap, but it's going to look good.
And yes, age does count - I couldn't get my ol' legs high enough to get into that thing...
Thanks friend,

Tom

PS - I would bet a 1.23 US that that is YOU in your first motion sim....I just know it is.

this is me in my first motion sim, joyrider, wiper, jrks.
Cheers, David.

As I understand, the main dimensions that have a relationship are as below, plus the length of the crank arms.

The sketch is from Ian's user manual for 6dof,

Any more sketchs there @telfel , suppose we can work out the ratios from this.
Thanks

A line drawing for my setup, the dimensions represent the ball end points on the platform, these dims give a push rod angle of 45" from the crank arm, and in the other plane the push rods are vertical.

Top ball end from motor pair attach to top platform on one pivot (bolt). 3 points of attachment

I'm hoping this will allow 6dof for flight (Ian's sw) and 4dof for racing, Pitch, Roll, Heave, Yaw, without complicated maths.



Top platform to mount seat, 700 wide, 650 deep with two channels forward to mount pedals etc.
