$5~$6 for 3' of 1/2" box tubing at lowes or home depot, etc. $3 for a pack of tamiya suspension stays from RPP $6~$10 for a lawnmower recoil spring $5 for nylon cutting board for cross braces Tools: $40 mapp gas with ignition torch $20 jig saw $20 drill and 1/8" bit. hammer vise grips, or channel locks bench vise would come in handy also. needle nose pliers. Procedure: Springs: 1: using the bench vise, measure out 4" lengths of the mower recoil spring. 2: use the channel locks to bend and break the spring off. 3: use the mapp gas torch to heat the end (last half inch) of the spring to a cherry red, then curl the end with the needle nose to make the loop for the mounts. 4: heat the ends of the spring to a yellow, then quench in motor oil. 5: do the next 3 leafs the same way Chassis: TVP version 1: pick out your body, 2: determine your wheelbase, (i traced out the body and fender edges onto 3 sheets of graph paper taped together) 3: figure out the ends of the frame (bumper brackets, brace for body bumper, or just over the axles) 4: decide on 4 link or leaf spring mounting positions (should go along with step 3) 5: sketch out a possible frame on the graph paper under the body trace. 6: use cardboard (like soda/beer case sides) to make a mockup. (I cut out the graph paper and taped it to the box side) 7: cut out cardboard skid plates and cross members and tape it all together. 8: put it under the body with your axles and trans and see if you like the layout. 9: take the mockup back apart and trace it onto your chassis material (nylon cutting board, street sign, etc.) 10: cut out the chassis pieces, file them to match eachother. 11: clamp the pieces together and then drill the holes, the holes line up better that way. 12: bolt everything together. Chassis: frame rail version 1: pick out your body, 2: determine your wheelbase, (i traced out the body and fender edges onto 3 sheets of graph paper taped together) 3: figure out the ends of the frame (bumper brackets, brace for body bumper, or just over the axles) 4: decide on 4 link or leaf spring mounting positions (should go along with step 3) 5: sketch out a possible frame on the graph paper under the body trace. 6: use cardboard (like soda/beer case sides) to make a mockup. (I cut out the graph paper and taped it to the box side) 7: cut out cardboard skid plates and cross members and tape it all together. 8: put it under the body with your axles and trans and see if you like the layout. 9: use the cardboard mockup as a guide for bending the box tubing, 9a: heat till cherry red, while clamped in the bench vise, use vise grips to make slight bends 9b: quench with water, then hold the cardboard mockup up against it to check your progress 9c: Once bent, Drill the holes for suspension mounts etc 10: cut the chassis in half 11: cut out the cross braces, either plastic pieces, or brake line sleeved all thread 12: bolt everything together.

Wow, Hair, you're on a roll. Keep it coming. If you were going to braze in the crossmembers would you use 1/4 X 3/8 flat bar stock? Also, how would you approach mounting the transmission and motor? |

If I were to weld in cross members (homie don't braze) I would use leftover chunks of the 1/2" box tube, cut, or grind the ends so they fit into the C of the frame, and tack it on the inside of the C. for a center skid and trans mount, thin steel sheet (16ga) would work well, weld it to the frame, then drill it for the transmission. Put paper or card stock i.e. 3x5 note card over the mounting surface of the trans and poke holes, then use it as a guide to drill. Last edited by hairba11; 06-28-2008 at 04:38 PM. |

| A couple more ideas....
Take your time and plan it out... In the end it will be worth the effort. I agree, first you need the body, then you can make templates for the chassis. I cheated and used Autocad to make my templates Here is an example of one chassis I did out of 1/2" alu box, Alu-welded together. Leaf springs on all corners Here is another out of the same 1/2" box but sliced through the middle A goofy leaf setup Almost finished (they are never really done) Be creative. I don't have any special tools, the rails were bent in a vise (carefully using pieces of pipe as mandrels) and the rails were split with a band saw. Other than that I used a hack saw, files, and a click start torch to "weld" |
