Default SCALE CJ 5 Crawler Project

This is the first few plugs I've made to create a scale CJ 5 body . I still need to make the windshield frame / floor and .firewall/rear panel and tailgate . but so far i'm happy . not sure if I should make molds and do fiberglass body or just vacuum form . I thought it a nice though to make the jeep in separate parts to give it a more scale look . any thoughts or ideas please feel free to post .

might as well add a few shots of the gas powered TFL chassis that will be going under it . it's a Toyan gas engine . I had to make a transmission from a HPI savage reverse module and a Axial scx 10 aluminum transmission as crawlers do not have reverse , I machined a mount for the engine and transmission to share so you don't have gear mesh problems and it's also easier to setup everything before you mount it in the truck . the transmission was interesting as I had to make conversion plates and also had to make a input shaft that would mate with both the output of the hpi module and the input of the axial transfer case . high gear gives me 30:1 and low gear gives me 60:1 so it should be able to crawl very slow. with the gas engine I will have no brakes so I ordered a set of the CAPO disc brakes and will be mounting them . I understand this will not be a competition crawler , more of a personal challenge for me as I like to build . cheers

4cyl, very nice should give a smooth throttle & great low end control. Took a look at the site, I could almost think about it LOL

Yes, I made some of the plugs out of solid pine blocks and a belt sander ,side panels and floor plugs are plywood .The vacuum table only takes an hr to put together . I just plug the table into the house vacuum and heat the plastic in the oven for 3 min . A 4x8 sheet of the styrene material cost around $30 and would be enough for 3 bodies . takes a bit of trial and error to learn . but I could repeat the process and make a new body in about a hr for $10 once you have the bugs worked out . I didn't think I would like the styrene as much as fiberglass but I find it looks much more like metal panels when formed . when using the .060 material it is very solid . I am also waiting for a HP407 kit to come in , it's a cheap kit that won't hurt my feelings to bash for parts . it has a frame and leaf spring setup very much like the CJ uses . I will just need to modify the three speed transmission to accept the Toyan gas engine .

just machined up some headlight pots and cut some lenses from lexan , next I will cut the grill slots and make some turn signals . the tail light pots I can vacuum form as they are plastic on my full sized jeep.

I have a full machine shop in the basement ,used my 14x48" lathe and turned them from aluminum bar stock , after I glued on some lenses and polished them to shape on the lathe. I've been in the hobby so long I need to take on bigger challenges all the time to keep myself interested . I am working on a method for making the wheel flares now , I would like to make them out of rubber because that is what the full scale uses and it would help reduce damage when they get hit .

Nice I have 12 x 28 myself, and mill both PM products. Machines are the bomb, I have not tried any RC stuff with them. Interesting the way you machined the light assemblies.

Cool I will be watching, and interested in the build process.

Well done

Yesterday I did some work on the dash the gauges are resized pictures of my full size CJ 5. the dash panel is removable by removing the window fold down anchor screws , the cavity underneath is the location for the drive batteries , I will be running a paralleled 6000mah 4 cell lion battery . I also made the heater vent functional so the drive battery can stay cool .

I also made the roll bar out of 5/16" brake line today , soldered together with mounting flanges welded on the ends and mounted to the floor just like the real thing . It will join to a cross member that attaches to the frame ,so it will be quite functional . I am sure just like the real jeep I should be dropping the windshield down when crawling so it does not get destroyed in a roll over
