the BIG one
Before we get started, I think a recap of all my projects so far, finished and unfinished, might be in order. :) Ok, so first there was this little thing. Was heaps of fun and I sorta wish I'd kept it the way it was and just built the next one, but hindsight is always 20/20 isn't it. Guess it's like with many things.... you never forget your first one. http://i433.photobucket.com/albums/q...ASHER00091.jpg http://i433.photobucket.com/albums/q...ASHER00142.jpg It then got rebuilt to this larger version http://i433.photobucket.com/albums/q...NSTER00020.jpg http://i433.photobucket.com/albums/q...NSTER00030.jpg I'm gonna rebuild this once again with a aluminium tube chassis this time, but still using the same motor, grinder setup and wheels. Then there was this in-betweener which went pretty well for about 10 minutes before I wrapped it around the only parked car in the whole street http://i433.photobucket.com/albums/q...HUSKY00030.jpg http://i433.photobucket.com/albums/q...HUSKY00037.jpg It then entered the eternal rebuild/design stage, where it still sits today.... http://i433.photobucket.com/albums/q...HUSKY00077.jpg http://i433.photobucket.com/albums/q...HUSKY00100.jpg http://i433.photobucket.com/albums/q...HUSKY00112.jpg http://i433.photobucket.com/albums/q...HUSKY00135.jpg http://i433.photobucket.com/albums/q...HUSKY00155.jpg http://i433.photobucket.com/albums/q...HUSKY00179.jpg http://i433.photobucket.com/albums/q...HUSKY00191.jpg http://i433.photobucket.com/albums/q...HUSKY00208.jpg I also started this big thing which never went much further than these pics. http://i433.photobucket.com/albums/q...4/STAR0017.jpg http://i433.photobucket.com/albums/q...4/STAR0034.jpg http://i433.photobucket.com/albums/q...4/STAR0064.jpg http://i433.photobucket.com/albums/q...4/STAR0066.jpg Then I chopped up all the steel frames from these projects and threw together something a bit smaller, but still pretty big, as another prototype for a large car. This is probably the size I'll aim for with this build. And I'll be using these front wheels too. http://i433.photobucket.com/albums/q...4/REC00027.jpg http://i433.photobucket.com/albums/q...4/REC00024.jpg http://i433.photobucket.com/albums/q...4/REC00025.jpg http://i433.photobucket.com/albums/q...4/REC00026.jpg And there's been a couple of other ones in between that never got much further than a motor sitting on the bench with 4 wheels. :) All in all it's been heaps of fun and I'm constantly coming up with new ideas and learning lots, which will, hopefully, one day, result in a home built large scale RC car that works well. 8) Videos of some of the cars here: http://www.youtube.com/user/hairyalien ;) |
RE: the BIG one
Nice to see you back on the track with something new, or something old that is getting something new:)
Funny to see those wheeladapters, they have exactly the same marks on the flat end side as i get when i have made something i my lathe:) But only when i make something a bit too quick that don't have to look so good;) |
RE: the BIG one
Nice to see you back on the track with something new, or something old that is getting something new New motor, new steel, new rear wheels, new ideas. I started making the front half of the frame yesterday. Will get some pics up when I've done some more. ...the same marks on the flat end side as i get when i have made something i my lathe:) But only when i make something a bit too quick that don't have to look so good;) Yeah I didn't worry too much about making them all smooth and shiny :) Just wanted to get it done quickly. |
RE: the BIG one
Oh, and those welds looks nice! Looks almsot like you have taken the step from MIG to TIG;)
|
RE: the BIG one
Nope.
Still using the same ARC welder as before. |
RE: the BIG one
Impressive work for an arc, what rods are you using? what ampage settings?
I posted an idea in your thread on the other site about another tube supply option |
RE: the BIG one
Thin 316 rods and not sure about the amp.
"Pretty high" :) Been doing a series of quick spot welds on top of eachother instead of trying to do a full seam in one go. Works a lot better. |
RE: the BIG one
Ahh, the 316 is just lovely to weld with! I have never tried anything that "ignites" easier than them.

RE: the BIG one
I have never tried anything that "ignites" easier than them. I have trouble getting them to ignite/arc, but once they get going they work a lot better than the General purpose rods. They create a lot of "crust" as well which pops off rather violently and usually ends up down the back of my shirt (or lower[:@]) Well, I'm off to the scrapyards to do some scavenging. Still need lots of bits and pieces for this build. Once I've finished the bottom half of the frame it's time for the thing I always dread the most - THE STEERING I am working on a C-Hub setup with fully adjustable camber and toe. Not taking any shortcuts with this build, and spending lots of time measuring and trying to stay 3 steps ahead of myself at all times, which is always a challenge. I'm feeling more confident this time around though and what I've learned so far from all my projects I listed in the first post is being put to use. It's funny too the comments/reactions you get from people when you tell them you're working on a steel framed RC car over a meter long. Was talking to a bloke the other day who's in to nitro and electric and he just could't come to grips with the size and weight of the car. As he's all about speed and doing jumps etc, he kept saying "But it's gonna be too heavy". I tried to tell him, it's not about going fast and jumping 2 meters in the air, it's about the challenge of engineering something from scratch and having fun whilst building. The motor is designed to pull about 100Kg at 50km/h so I think it's gonna be strong enough to pull a 20-30 kilo car. (Or however much it will weigh once finished) He still didn't get it. Ah well... http://www.intpcentral.com/uploads/headpat5.gif |
RE: the BIG one
Hey DV, it's coming along nicely mate.
I saw this quote mentioned on another website, and when I read it, I thought of yourself, Lars, Vass, Sam, etc., etc. Quote: Thomas Edison once told a group "Experts" that Inventions are made by people too dumb to know they wont work" I have that as one of my rules to live by. Smokey Yunick said, "One good experiment beats 1000 expert opinions." I have found that to also be true as I can tell you have as well. My German cousin's husband who was a Formula 1 Engine designer for BMV one told me in his accented english 'Don. A leedle beet mehr is always posseebull. " I have that posted on my shop wall. It was immediatley obvious to me why he had his job!END QUOTE. |
RE: the BIG one
All good thoughts Mudgy, cant have enough of them for the shed walls for those times when things keep going wrong

RE: the BIG one
Getting a bit more done slowly slowly.
Too damn hot in the shed... 42 degrees just now. Sucks when you're welding/grinding as the metal takes forever to cool off. Front lower half of the frame taking shape. Even got the chalk out and scribbled a bit on the floor :) http://i433.photobucket.com/albums/q...C/BIG00019.jpg http://i433.photobucket.com/albums/q...C/BIG00020.jpg Trying to keep everything as square as possible http://i433.photobucket.com/albums/q...C/BIG00021.jpg Starting to look like a car now. |
RE: the BIG one
edited and deleted LOL

RE: the BIG one
O......kay
Thanks for sharing that with us all. |
RE: the BIG one

RE: the BIG one
ORIGINAL: mooman007uk coming up with the necessary jigs to keep everything lined up and square in 3 dimensions I find is the part that requires the most thought, time and beer Indeed. I recently bought one of these http://www.toolnweld.com/Images/923/...ngle_Clamp.jpg Which helps a lot. I tried using those red triangle/arrow shaped magnets but found them useless. Not strong enough to hold the work pieces in place. For the odd angles on the frame I'm making here, I used lots of little welding clamps and a 15mm thick aluminium piece to hold it all together. |
RE: the BIG one
ORIGINAL: Soloratov unimpressed......:D |
RE: the BIG one
what i mean to say is that its good to own a welding machine cos then your able to do alot of home hobby jobs in rc such as youve done here
|
RE: the BIG one
Oh ok.
Yes, yes it is. :) Sorry, your post just seemed like it was typed by a squirrel who'd had too much red cordial. ;) "I'm a pro welder LOL I don't have a welder LOL I do all my welding at work LOL I need to get a welder LOL so I can weld at home LOL." |
RE: the BIG one
vinylpusher weve got the same brain lol start building then while were building we think of another project hmmmmmm start the other project and leave the other one s that are nearly finished on the side we need to see a doctor lol
|
RE: the BIG one
hey man you don't wash your hands a hundred times a day?
just kidding mate, it's looking good. Geez you could forget the steering servo and just sit on the thing and steer!!! ;) |
RE: the BIG one
i dont see the point of this thread , we seen all this stuff in the other threads youve made , there was no point making a new thread about all the previous stuff youve already posted up before lol
