    I guess it would depend on what type of motion system he used; seatmover, platform, etc. I ran the numbers, although I am not sure I did it right ;) and it appears that 6 of them would have a stall rating of 618lbs? So a platform of around 300lbs should work just fine? I figure half of the stall rating?

    Thank you Historiker, Sorry I didn't remember your name. The big hydraulic units are setting on the back of my property, they will require a lot of money to get going. The 6 dof projects are much more realized.

    He did say a 6Dof - which I guess will be a Stewart Platform. - Not knocking - they may turn out fine, just saying it takes allot of optimism to purchase 20 of those motors which as far as I know are untested in a operating six DOF.

    Now that they're at 50$, making an offer of 45$ it would be 80€ for two.
    Paying just once for delivery it would have been about 140€ for both motors, I'd say an affordable price.
    What doesn't make it affordable is paying s.s. for each motor

    OT: Nice new avatar @noorbeast , had to check twice before I could recognize you, I was used to your old one you had since I first seen this forum

    i am planning a 6 dof with these but haven't started anything except gathering parts. I am thinking kind of a mix between joyrider and stewart platform. 300+lbs is a lot to work with. ty @Historiker for the math. also mm as half bridge, the cosel 50amp did shut down on heavy loads until i wired in parallel.

    Yes, but the Stewart Platform would be supporting just the driver (seat mover) the driver and controls, etc. Mine has everything including the monitors so I was wondering about the overall configuration. I agree that a 1000.00+ USD is pretty optimistic but more power to him I say :)


    EDIT: @bruce stephen , don't thank me too quick; my degrees are in Humanities not Mathematics. I might be way the heck off :D

    already have the motors so no turning back now. I'm confident though. i can stand and bounce on my 105mm arm and the m,otor holds me just fine. i weigh in at about 170lbs. so 6 should have no problem. Controls pedals and wheel will be part of it but I'm going to go static with the monitor. Its mainly going to be built for IRacing as I do not play many other games. I use dirt3 for testing but IRacing is my shit.

    Bruce, Thanks for the testing. Some confidence gained. Ordered 20 5/8" couplers with keyway yesterday. They will be welded to CTC levers.
    Later,

    Yes when I finish my contract (work) for this month I will have time to switch from monsters to JRks on my 2dof to compare the difference. I already have them just need to hook them up. My 6dof may be a hybrid. Mm+jrk. Jrk for the two front motors and mm for the rear 4. gotta sketch whats in my head. Will post when i do. Not sure if ill do it this weekend cause i may be racing instead week 13 though so we'll see.

    Definitely post results and let the community know. I wanted quarter sawn douglas fir for strength for the build but at $19 for a 2 x 4 eight feet an alternative may be in order.

    What about white pine studs? Not sure though. They are cheap here but may not be in your area.

    They are but finding straight and low small knots is a challenge. It is hit miss and many trips to dig through wood stacks. At $19 a piece, that is becoming motivation.

    I might have missed something, but why do you need 2x4 strait grain boards?

    Something to consider; big box hardware stores have select grade 1x4's that you could laminate with wood glue and clamps.

    I do understand the cost of the Douglas fir, 1/4 sawn doesn't cup easily and so makes great planking, etc. And of course straight grain boards are valuable for aircraft building (kit planes) ,etc. And it is very spendy. Just not sure where you are using it?

    True. But select grade boards are usually quit expensive also compared to standard ones.

    All true. Strength for Stewart 6 DOF. I know Silent chill used fir that is clean of large knots. I agree about 1 by lumber being clean and laminating together will produce a stronger rigid member.

    In my neck of the woods we call it plywood.;) If you have the right tools to make strait cuts out of a 4 x 8 foot piece there's no reason why one couldn't further laminate them into thicker pieces if you don't mind somewhat rough edges. If you do a little filler and sanding should take care of that though.
