B C Posted August 26, 2017 Report Share Posted August 26, 2017 Love the update and the plans you have! Steel or alum for the suspension? I see two points in your design that I would do differently with your suspension design but overall it looks good! Have you calculated Ackerman angle or modeled in the roll centers? Just curious. I know this isnt a racecar but im fascinated with your build Quote Link to comment Share on other sites More sharing options...

I see two points in your design that I would do differently with your suspension design but overall it looks good! Have you calculated Ackerman angle or modeled in the roll centers? Just curious. I know this isnt a racecar but im fascinated with your build The control arms will be tube steel. I have accounted for some of the angles. I will be running a very stiff spring rate. With low travel. With taller profile tires. So the tires absorb most of the bumps. This is the look I'm going for. I will be setting this car up for auto cross.

Jdesign Posted August 28, 2017 Report Share Posted August 28, 2017 This is sweet!! I am glad you are still hammering away on it even though you hit so many bumps so early in the process. James' F20 powered model A will always be a sweet build, if done right, I see this heading the same direction. ThatRatRodProject 1 Quote Link to comment Share on other sites More sharing options...

ThatRatRodProject Posted October 18, 2017 Author Report Share Posted October 18, 2017 Another update. I started making the standalone engine management wiring harness out of the oem harness. Im shaving all the unnecessary plugs and wires off the harness. Sent from my iPhone using Tapatalk jc43089 1 Quote Link to comment Share on other sites More sharing options...

ThatRatRodProject Posted October 18, 2017 Author Report Share Posted October 18, 2017 What management are you planning on using? Wiring always sucks. Stock Ecu and custom fuse box.

ThatRatRodProject Posted October 19, 2017 Author Report Share Posted October 19, 2017 Great progress and success today with my custom wiring box. I have an official standalone engine management system for my M60b40. After reading a lot of wire diagrams and taking a step out of my comfort zone. it all worked out in the end. This is the first time I've done any really serious wiring on a car. --Ill let the pictures do the talking Before After Sent from my iPhone using Tapatalk jc43089 1 Quote Link to comment Share on other sites More sharing options...
ThatRatRodProject Posted February 14, 2018 Author Report Share Posted February 14, 2018 Another update. I recently order a lot of supplies to get my project. This is going to be a picture update. And I designed up some clutch and brake pedals. Not ordered yet but soon will be the tires I am looking for a 3.73 or 4.11 medium case diff.

ThatRatRodProject Posted September 28, 2019 Author Report Share Posted September 28, 2019 So it’s been some time but this project is not dead. Updates will be coming. Re-designed front frame section sneak peak. P_Roloff, Jdesign, SteelBlue and 2 others 5 Quote Link to comment Share on other sites More sharing options...
Jdesign Posted September 30, 2019 Report Share Posted September 30, 2019 Nice work! Solidworks? I have so many questions.(Sorry) Is there a reason you are going with a cantilever set up? How did you calculate the the pivot arm length? Are there any shear concerns with the shock mounted on the top of the tube like that without any linear support? You obviously peaked my interest. I like what I see and I am very glad this isn't a dead thread. Quote Link to comment Share on other sites More sharing options...
straight6pwr Posted September 30, 2019 Report Share Posted September 30, 2019 very cool! 27 minutes ago, Jdesign said: Is there a reason you are going with a cantilever set up? seconded. it appears there is room for the coilover where you've placed that yellow connecting rod. are you using an undersized spring/shock and but increasing its effectiveness with the pivot arm? what is the connecting rod coming forward from the pivot arm?

There is a couple reasons why i have the coil-over mounted horizontally . 1. Keep it Clear of road Hazards like Dirt, rocks, Ect. 2. I am using a under rated spring. So with the Cantilever allows me to achieve my desired spring rate with some sacrifice of overall suspension Travel. Because i honestly don't know what the project will weigh in at. I may have to re-fabricate the Cantilever Section. But This may be to stiff. Quote Link to comment Share on other sites More sharing options...
GunMetalGrey Posted September 30, 2019 Report Share Posted September 30, 2019 Yeah this project was always intriguing, but has certainly caught more of my interest seeing things being modeled! The shear area on that upper shock mount seems reasonable if you've got good penetration welds on both plates. I think I saw the knuckles in a picture on a previous page, but are those a standard purchased component? I've always thought it would be cool to do a ground up build like this, so I really look forward to the continuation of this! Quote Link to comment Share on other sites More sharing options...

ThatRatRodProject Posted September 30, 2019 Author Report Share Posted September 30, 2019 Quick update. with some actual fab work being done. The past couple weeks I have been putting in some hours gettin some of the front frame done. I’m gonna attach some photos if you have any questions let me know. I’ll try to explain. 68146F60-B7C9-405D-9388-5EEEE2580392.MP4 3313FB85-223C-4B49-A9BD-F9EC8D2293C1.MOV 65AD28E0-186E-4B34-8577-045E1CC9E60F.MP4 9070B11F-FE72-4710-8BD4-5062AADA8845.MP4 BC8E10B8-81C0-4EF0-8CC0-98251DCCA8DB.MP4 m42b32, Jdesign, HipMF and 1 other 4 Quote Link to comment Share on other sites More sharing options...

RobZR Posted September 30, 2019 Report Share Posted September 30, 2019 4 hours ago, ThatRatRodProject said: I would not recommend using a stripper bolt in this manner. They are not intended to handle lateral forces and have a inherent stress riser at the base of the thread that is prone to failure. Ideally you would support both sides of the pivot point from the subframe. if you must support it from one side a spool and bolt design will bend before failure, since it keeps the bolt in tension.
