Thanks for the vid Dave. Yeah, I'm not planning on doing anything with heave or surge. Heck, Ill be good getting the 3 DOF down. Asked more for understanding. But who knows, maybe something come to me. Actually surge wouldnt be too difficult I think. The thing you showed in your response is pretty much it. Have the whole thing on some wheels/casters and have an actuator push/pull it. Hmmmm Would nee to have something substantial to attach the actuator to on the 'base' side....
Could use a couple of cable winches and pulleys to drive the entire rig like a cart if you could mount them directly to the floor or wall. Then you wouldn't need an entire other frame under the slip frame, just casters on the slip frame. Fun to think about what is possible.
@@Rebar77_real True. that would work.. It would be nice to see some of the mechanisms in small scale maybe out of paper or wood just to see whats up and if there are issues to overcome.
I thought about making the slider platform at one point but I'm pretty happy with the 'surge' I get already. I think he needs that type of surge platform because they use those 4 actuators to move the upper frame. And they dont seem to have as much 'travel' as mine when I accelerate.. Hard to really compare without 'testing' one of those platforms out.. Could be awesome! I just dont know ..
I wonder how much 12v motors can be safely overvolted for a performance boost. It would depend more on cooling at that point, eh? Besides the quality of the motors themselves I mean. Cheers.
Yeah, probably a little. The Truck battery runs about 13.6 v I've not noticed they get warm or anything after a couple hours of hard racing.. The Crab pots did not come with any documentation. I dont even know who makes them, just where to get them.. I have seen guys on x sim attaching 'fins' the the motors to assist disapating heat.. but I think that by using more leverage, the motors work less hard.. My designs seem to be quite different than the DOF reality.. But I did look up their motors Thanks to SIM Garage tearing a DOF rig apart and showing the part number.
Hey Dave do you have a 3D printer? You could probably get a ton of use out of one for all the custom stuff you are doing and people have already made tons of free things for you to print like housing for your aurdinos and motor controllers even add-ons for your rig. They've come down a lot in price and you can even diy one and build it yourself. Anyways thanks for the videos 👍
No I don't have one. They seem interesting and some of them actually print with carbon fiber.. I just have not had much time these past few years to look into one seriously.
@@DMAX_DIY those Carbon printers are sick but are industrial level printers so they still cost a pretty penny. PLA printers are pretty cheap though and can do some solid prints with nice rigidity. I'd recommend looking into the Creality CR-10 or Creality Ender 3 Pro they are both a great Value pretty easy to setup and have a ton of upgrade paths. I think it would really level up your builds 🤙
@@RicheyBLS I've watched quite a few of those Creality Ender videos.. And yeah they would probably be a heck of a good addition.. That's the one I would probably get. Have you seen this channel? he does use that product.. but also makes carbon fiber stuff.. I bought my carbon fiber supplies (for building an upper frame and seat a little while back - have not done it yet.. and it's not prepreg so I dont have to worry about it going bad).. anyway.. here is the link.. He doesnt talk at all during the videos.. just makes some stuff.. Big Big Following.. I probably should 'follow that advice" but I gotta talk for some reason.. hahah. www.youtube.com/@ECOLAPStudio
@@DMAX_DIY wow that's really cool! I never thought of using 3D printed molds to make carbon fiber parts. It's crazy the kinda stuff you can learn on the internet. But don't go mime on us I think all enjoy your humble attitude and diy every man kind of style. 👍
I am building the semi-space frame in attempt to eliminate some weight on the upper frame but make it stronger than it would be with increased steel thickness. There was a study done by some guy who builds race car frames and I watched his 'tests'.. So rather than getting thicker (and easier to weld) steel, I'm pointing in the space frame tubing design. I could 'mic' the metal I generally use when I get home but I bought it all at LOWES.. it's pretty thin for the square tubing..
Great question Ultra Instinct! I've been thinking about that too.. the amp load per motor will go way way up.. that's for certain (because there will not be a u joint holding the majority of the top frame weight).. I have six of the crab pot motors but to use them in something like this I would need to disable both of my motion rigs.. ** not ready for that yet** but I will in late 2023.. cause I want to see if they will work in a 6DOF.. So the answer is.. IDK!! they might? they may not handle it.. 6 would spread out the load better than 4 .. just saying.. Dave
@@DMAX_DIY thanks for the response.i also had the idea of "I want to see" if it will work. But if ever you do try please upload. Because I plan to do it as a project for the year. I'm in no rush
question - is there a reason you don't mount 1 motor on the middle of the front for pitch, and 1 motor next to your right hip for roll? Rather than using the 2 motors at once to combine everything. Does the way you're doing it make the motors work better or something?
Thanks Dave!
you got it brother. This is kind of a Q&A video.. not a lot of meat on the bone.. but I got a real good one coming up .. Dave
I want to race that thing in the corn fields!
It's pretty tall.. I see 'em out here in AL all the time. This one was just flying though!!

Have a good day Dave !!!
I'm tryin to!! You too my friend!
The in-depth breakdowns in the new series should be really helpful. Thanks for sharing your knowledge with us, D Max 😎
Your the BEST B! Thanks for watching and commenting.. The new rig is just about ready for POWER. DMAX
Hi dave.
Thanks for all, i m going to need your help when i start my sim rig
Absolutley! Thanks for watching.. Next video coming up soon.. It goes over what parts and things you would need to get started..
Great video Dave.
Thanks so much for watching Megasaurus55!! Epic !

Hi, what width/thickness do you recommend for the steel tubing (for a good balance between weight and rigidity)?
I am building the semi-space frame in attempt to eliminate some weight on the upper frame but make it stronger than it would be with increased steel thickness. There was a study done by some guy who builds race car frames and I watched his 'tests'.. So rather than getting thicker (and easier to weld) steel, I'm pointing in the space frame tubing design. I could 'mic' the metal I generally use when I get home but I bought it all at LOWES.. it's pretty thin for the square tubing..
the motors you use for your 2 dof. can it be used to make a 4dof instead of actuators? (like the four wheels on a car layout(no yaw).
Great question Ultra Instinct! I've been thinking about that too.. the amp load per motor will go way way up.. that's for certain (because there will not be a u joint holding the majority of the top frame weight)..
