Crammy's project No2

Hi Guys
I wouldn't mind a bit of feed back on this, either good or bad.
As some of you know i have built my rig using actuators. The down side to these is the noise as they are not the quietest of units.
I am aiming to build something similar to below to keep the noise undercover so basically decided to flip the actuator upside down and encase. obviously there is still designing to do but should show you the idea.
there are 4 actuators in the corners and the seat frame sits loosely on top which is just the opposite of what i have now.
It would have traction loss still so was thinking of using door bar brushes or similar to help seal in a bit of sound as the whole base would need to move.
cheers all

It looks pretty cool to me,,,,,& if it masks some of that squeaking from the actuator's then i'd say go for it ,,,
i guess if you sound proofed the inside's where the actuators are you could get some decent results ,,,

Just a suggestion as to design. I like the initial drawing but what if you introduced a vertical angle of approximately 30degrees to take advantage of the torque. And place the actuators at 45degrees from the rig (off the corners). This will give a similar effect to a Stewart platform.

Not to sure if that would work @bruce stephen . With only 4 actuators i think the platform would colapse.

Anything to keep the squeek out would be good @stevemontuno. Soundproofing would be good and not to expensive.

this project wont be started for a while but i will spend time designing and working out weights

Hi,
you can maybe check the first project of @willaupuis

Its similar being boxed in @Wanegain but im using actuators from my first project. im just flipping the frame. i hope to get this underway in a couple of months but got a lot going on with work and my house at the minute. Once i have time to get drawn up i will post the frame drawings and not a sketch up image

Well 7 months later i have finally got round to getting this project underway. i will be starting the framework at the weekend.
I now have a CNC 8ftx4ft plasma table so will cover the entire unit with aluminium floor plate and try and keep in the squeeking of the actuators. the base will be About 15mm of the floor so i will be fixing brush strips to the bottom to seal that gap a bit.
I have attached a drawing of the frame work. the yellow dimensions havent shown up though but i can put these up in anyone is interested in making it, (if it works lol).

I have left off the seat, wheel and pedal mounts as i havent worked this bit out yet. i will probably get these bits built and sit my gt omega on top to work out the dimensions from there.

the pivot point for traction loss is in between the 2 front wheels, then i can angle the rear wheels to suit the rotation which is what i did on my first project.

It is quite similar to my origanal sketch up model.

Cnc plasma...sounds fun....

We got it at work mate. we keep sending stuff down the profilers, so just bought a machine. it will be set up next tuesday. what we save a month should pay for it, and ill try and bring work in. It will be mainly used by me at weekend though, nothing to do with work lol. I'm trying to get my hands on a pedal kit that i can cut out of aluminium plate.

If you have access to Iracing forums beano has a tutorial in either DIY or hardware for a pro pedal build. It's been awhile since I read it but he uses will wood I think and hydraulics. Worth a look.

@bruce stephen I cant access the forums as i havent re-signed up yet. i didnt want to pay while im stripping the rig down as i wont get used. i will sign up again as soon as im finished

And so it begins. best get welding at the weekend

Hey, just a quick question that I can't quite tell from your drawing, are the actuators going to be fully fixed? Or mounted on U joints? Also let me know how the CNC plasma performs, I might get the chance to play with one in the near future

@Tim McGuire The actuators are fixed. i havent drawn the plate on top of each post. on the underside of the seat frame there are 48mm scaffold tubes 35mm long. the tops of the actuators go in here unfixed, so the top is floating in effect. i couldnt fix them at this point due to the distance between them changes with angle and being 4 actuators there can always be one that isnt touching slighty. Each tube is also covered in rubber on the inside to stop metal on metal contact.
it works the same as my current set-up but just upside down. ive attached how it is now so you can see. the idea is to box the actuators in to hide sound and cabling.
im going to check the room once the front actuators are in, and if there is room ill put a couple of speakers in there facing the seat too.

@crammy, thanks for clarifying, I was curious how you were going to get around with the distance between the actuator points changing depending on platform angle

no problem @Tim McGuire. I drew it out on Autocad with the actuators at 900mm centres. i then rotated on the tip of 1 of the actuators so it was tilted, and the distance between tips changed by 6mm. It works really well on the existing setup.

@crammy there wasn't a post tag for jealous so I just liked it

My wheel buttons/paddles and QR has arrives so will post a pic when home tonight. They seem a decent bit if kit. The QR seems to be made of plates clamped together, so that will be coming apart for inspection and a DXF made for the table so i can knock up another couple for future wheels.
