Finally had the day at the public workshop.. Although I had some introduction course, being on your own is something else.. the Lathe is an impressing machine :-) But any way I managed to get the base for the rods done.. I first need to make the treads otherwise I could stress it too much they told me.. but the holder for the cutter is missing so I will do it manually but need to buy me a tap set, as I don't know how to do it on a lathe :-) So I started cutting the part of the topframe. too bad that 60 degrees was unfortunately not possible so I need to find a solution for it. probably with a grinder.. So for now I miss the 2 bars at the sides to make the 90 degree bottom square. That way I can fit my current aluminum frame on top!
But any way here are the parts layed out, not welded, need to make the holes first and need to finish the rod holders!!
I am pretty satisfied so far, nice to see things come together instead of a picture on the desktop!
Next weekend I will do the alignment parts and bushes on the lathe so I have more degrees in the angle, make the holes and prep for welding!
Right now I have got my aluminum for the cabinet and for the floor of my current rig.. So that I can put the rig on my platform..
and today a truck came by to deliver me a box of Chinese goodies..
With ... inside!!!
Currently doing all kind off stuff..
Design the lower platform.. now that I have the motors in I have the right sizing.. Install the cabinet with the VDF's, line filters etc.. still deciding on the OSW steering wheel if I should put it inside the cabinet or not..
and prepare for welding next Saturday with a pegboard..
All in all, busy and orders are coming in.. next up coming in is my wires for the Motor and potmeter.. So that way I can do some work while I am at home and not at the workshop!
Looks really good you're prep steps! I'm also dutch and gathering as much info as i can. I will keep it english here so everybody can read along ;-) I think i will be building my full 6dof somewhere at the end of this year. I have currently a mini setup made to check it all out youtu.be/hFb0ktyQUb8 I don't have much experience in designing the mechanical stuff (more a electronica guy) so i'm really looking forward to your build ;-) And perhaps (if you don't mind) make mine similair to yours..... Hope to see future updated! ;-)
You are more then welcome! I have all the designs here in Solidworks.. But I think I have a bit different approach in designing :-) I design the things as I go along :-)
Having the final parts at hand makes it easier for me .. and notice some fails..
Like for instance.. I have finally welded up my top platform and as I also received my motors and now I will design my lower platform and motor levers..
And I am glad I did it this way, because when I looked at my motors I saw that the output shaft and flens ..Not sure if it is the correct word ( the connection plate of gearbox and motor) is not leaving me enough space for a 'straight' lever..
So I designed this as my lever, this would clear my 'flens' part.. but also causes the lower platform to be 6cm wider!!! so good thing I caught it :-)
holes wil be 190mm apart.. Any faults in this Idea... I want to be able to let the axel rotate 360, just in case things go wrong, but prevent the lever from hitting the gearbox plate!!!
Finally my welded top.. The first time welding.. but I am satisfied.. Also the top frame will be mostly hidden too :-)
It is 780mm wide so it can take my current cockpit.. Although that frame is now 200cm long it will be shortened down to 150cm..
The frame will be connected to the top platform with a few plates and bolts in between there will be a aluminum tear plate sandwitched .. So if all is right I should have 8 connection points between frame and platform.. I think that it won't come off any soon then!!
and running 0.75Kw motors should give any problems..
Next weekend I'll hope to have started on the levers and lower platform, first finish the designs and order metals.. Meanwhile I'll be working on the electronics cabinet..
If anybody has an idea or opion please let me know!
Oh btw.. I am intending to wrap the entire 6-dof frame in carbon look foil.. I think that would be really cool as I don't have any place I can paint it or leave it to dry!
Sorry for the earlier deleted posts....it's sunday morning and wasn't paying attention ;-) The way you design the stuff "go along" is exactly as i do that most of the times ;-). Top plate looks really good!! I will keep a close look on this feed/forum and if you need help in electronica stuff i can perhaps help... (not that i did a full build ever but....perhaps i can think along). Hopefully i will be as far as you are at the end of this year ;-)
Managed to squeeze out another day st the public workshop
Cutting up 20 meters of tubing in varous sizes and welding.. Nice to see things are getting somewhere and it really starts to look like a 6 dof sim.. :-) (finally)
Test fitting and it fits :-)
Lower frame beams.. welded and fitted with the motor mount .. it fits..
could resist and had see how big it would be and how it looked.. Now I have to clean the welds, weld some crossbars to the angled pieces and drill a few more holes.. But I had to try a 'partial' weight test .. I can stand on it and now movement at all :-)
I am F*ck*ng proud thus far.. Big smile from ear to ear .. How will I feel if it actually works??
From being a software engineer to a metal worker.. next up .. be an electrician!!
BTW. The black bar is a temporary try.. It is a carbon wrapped.. I will wrap the whole frame in carbon foil.. It looks really cool.. also due to lack off space for painting (bad weather and no garage, so it needs to be done outside.. But once build it won't come apart any soon I think!)
PS..damnn.... after looking at it for 5 minutes I notice a major mistake.. the diameter of the lower frame is too small.. (I need to make the corner pieces longer!!!! by 50mm on each side.. So glad I looked at paulg100, intended to bolt it instead ow welding it too the frame!!) If I put the lever on the motor all rods will be angled outwards.. :-(
A new issue for next week.. but heck . stil proud :-)
Having the motors and frame bolted has already saved my arse due to the lower frame not lining up quite right. After torquing the bolts hard with nyloc nuts it is damn solid but i guess once mass inertia comes into play that will be the real test. If need be it will be fairly easy to tack weld things together if a bolted frame is not sufficient but hopefully thats not necessary.
and yeah its a great feeling seeing the new skills and hard work come together !!
Actually I need more then 50mm on each side extra.. I guess I'll make the levers and rod bar first.. then I can measure it directly and adjust the drawings on my findings..(getting the new radius as I need the radius for the FFB software I guess !
Any good docs on what we need on all the various dimensions and settings? Because I want to start the sim at really small movements first so that I can tune that in from minimal to maximum instead of tuning down. The change of breaking stuff in going up is less then start all maxed out!
Any tips on setting up and tuning are really welcome!!! (I'll be using the FFB software, as I've read it is the best around for racing! I now have XSimulator on my 2-DOF, but will part from that one I think) .. Any suggestions in that area are welcome too?
Ah well.. Any suggestion is welcome..!! Seeing many up and running Sims here, I guess there are enough headaches gone by, please prevent me from having them :-)
Personnaly not yet tested bff software but all one who use it are pretty happy. Form my side I use xsim3 and it works great also eventhougt the plugin would be tuned ( dificult to have flat surge or sway) .Wouldn't it Thanos ;-) ;-).
But As I use pitch and roll to increase the G-forces feeling sway and surge not flat didn't disturb me at all.
Any soft you will use there is enough people to help you.
Very very nice Mhensen!!! You have surely a thing to be proud on!! And i will keep a VERY close eye on this thread... As the level of quality you are building this i am also looking for ;-) So thinking about taking you're example looks more and more plausible ;-) Keep up the great work mate :-)
dureiken: Hi there, it's really quiet here someone could help me for my 6 dof project ? thanks a lot

fimmy: How's the firmware going?
Sept 6, 2017 8:34:43 GMT
tronicgr: @fimmy I had to put it on hold to finalize the manufacturing of the new kickstarter controllers. I tested parts of it to ensure compliance with the new features and looks good so far. I'll get back to it soon for integration.
Sept 9, 2017 12:52:35 GMT
Theuns: Very nice design.I'm also busy with mine and changing it also to Linear Actuators with 220v Servo motors.I'm waiting for my new controllers from Thanos. If I may ask Do you have any Sketchup files of your design and willing to share it I Thanks Theuns

atayeu: Hey everyone! I'm reading up and gathering all of the intel I can find for my first motion platform. this is by far best information for creating one.

tmcnam: I must be crazy but I still can't find the blueprints to the platform by GA-Dawg. Any help would be appreciated. Thanks guys.

Trip Rodriguez: Sorry tmcnam, the shoutbox doesn't get much attention. Did you find the blueprints? They are at the VERY bottom of the extremely long first post. It says "attachments: 6DOF.zip
