91blaze Posted February 24, 2012 Posted February 24, 2012 I recently came into possession of a go kart so I thought it would be fun to make a model of it. This is my first time making anything like this so any help and tips would be greatly appreciated. So far I'm almost done with the main frame which I'm making from brass rod that is 1" on 1:25 scale. I know it will be tough to make certain parts like the tires and engine. If you guys could help give me ideas, it would make it much easier on me. On to the pictures: 1:1 Go Kart: Frame so far: The frame is nearly completed and next I will be working on the suspension and sheetmetal parts of the go kart. If anyone has ideas on the wheels and engine, let me know please.
vwrabbit Posted February 25, 2012 Posted February 25, 2012 Nice looking frame! Wish I could help ya w/engine and wheels. I'm sure someone else here will have an idea! Tim
High octane Posted February 25, 2012 Posted February 25, 2012 An off-road go kart? I didn't know they were ever allowed on the road, on ANY road?
Ryan S. Posted February 25, 2012 Posted February 25, 2012 Cool project. It's nice to have a 1:1 so readily available for reference . I'm no help on the engine but you might want to look at some Lego kits for tires of the right size.
vwrabbit Posted February 25, 2012 Posted February 25, 2012 I was also thinking Lego tires, but they aren't very rounded on the edges. Tim
Joker Posted February 25, 2012 Posted February 25, 2012 The Drag-U-La has a motor for the surfboard..like a lawn mower engine
91blaze Posted February 25, 2012 Author Posted February 25, 2012 Thanks for the suggestions. I want to build the engine from scratch so if you know someone who has done so before, please let me know. An off-road go kart? I didn't know they were ever allowed on the road, on ANY road? There are go karts that are used for racing on tracks then there are ones like mine that are capable of driving offroad and through rough terrain.
91blaze Posted March 9, 2012 Author Posted March 9, 2012 Got a new camera so here's some better pictures of the frame. I have been busy lately so I don't have any new progress.
Chris guthro Posted March 9, 2012 Posted March 9, 2012 thats cool!!! maybe go all out and use a supercharged vtwin
91blaze Posted March 9, 2012 Author Posted March 9, 2012 Haha yeah that would be cool. I'm thinking about making a sandrail when I'm finished with this and I'll be sure to put a supercharged V8 in there.
Romell R Posted March 9, 2012 Posted March 9, 2012 Hey youre doing a good job so far, is that chassis a bit fragile? Looks like your building it with glue, Id like to make a suggestion if youre gonna build it from brass try soldering it together with silver solder, its not hard to learn and it will make that chassis your building solid as a rock. On the other hand if you must use glue try building it out of styrene. Its alot easier to work with.
91blaze Posted March 9, 2012 Author Posted March 9, 2012 Right now, I think I'll stick with the epoxy I'm using as it seems to be fairly strong.When I start the sandrail project I'l try using solder, but this frame is already nearly finished so I'm not going to worry about it. Thanks for the tip though.
Rmodeler Posted March 9, 2012 Posted March 9, 2012 Romell's right! By the way, Radio Shack has a very skinny-diameter solder called "Silver Bearing Solder" that works well for me. http://www.radioshack.com/product/index.jsp?productId=2062725 Also, I use one of those small hand-held butane torches instead of an iron. Best of luck!
91blaze Posted March 9, 2012 Author Posted March 9, 2012 (edited) Can I solder the frame while its glued together or would I have to take it apart? Also, is silver soldering just like regular soldering, cause I've soldered electronics before. Edited March 9, 2012 by 91blaze
Romell R Posted March 10, 2012 Posted March 10, 2012 Can I solder the frame while its glued together or would I have to take it apart? Also, is silver soldering just like regular soldering, cause I've soldered electronics before. You'll probably have to take the glue off cause its gonna burn , and the soldering part is pretty simple , its alot like eletrical soldering. Make sure you have flux to flow into the joints then put some solder on your hot iron and touch it to the joint the solder should flow into the joint and make a solid connection for you. It'll take a few trys but you'll get the hang of it. Check out my Promod build (the link is in my signature) and you'll see the brass chassis I built. Have fun with you new project.
91blaze Posted March 10, 2012 Author Posted March 10, 2012 Thanks for the help. I think I'll try soldering it, but I don't have any soldering equipment so it might be a while before I get further.
91blaze Posted April 4, 2012 Author Posted April 4, 2012 Alright, I got a cheapo Radio Shack 40 watt iron, the solder you showed me, and a "Helping Hands" stand, which has really helped. The only flux I could find was rosin paste, which is probably not the right type, but I bought it anyways. The solder just wants to stay on the iron, but I managed to slowly get a few joints made. I'm taking a break to work on another project, but I will update when I can. Here's a few pictures: The "Helping Hands": Not pretty, but it works:
manley Posted April 18, 2012 Posted April 18, 2012 you need to get silver solder. It cost more but is clean, not like this mess.
