A couple quick updates: Getting the car ready for USCA at Thunder Hill next month. I finally got my roll bar painted. And who ever told you you can't build your own leaf springs?
Mike built the cage for me several months back. He did a great job and it is a very tight fit in the interior. I finally got ahead on my "Honey Do" list and pulled the interior back out to spray it before it got too rusty. http://i885.photobucket.com/albums/a...psac69a630.jpg http://i885.photobucket.com/albums/a...pscdb9502e.jpg http://i885.photobucket.com/albums/a...psdfd928dc.jpg http://i885.photobucket.com/albums/a...ps87728d11.jpg http://i885.photobucket.com/albums/a...psd6e647ab.jpg I actually modified my leaf packs before the November GoodGuys, but I figured you guys would like to see them anyways. Went from a 155# to about 185#. Really keeps the nose down better (no longer lifts the inside front), but my tires are too shot to get a good idea if it will be any faster. http://i885.photobucket.com/albums/a...ps0dedea8a.jpg I added an extra leaf below the main, flipped the old #2, and added a new #3, and an anti-wrap leaf to the front half of the pack. http://i885.photobucket.com/albums/a...psfcfdc243.jpg Formed up a bunch of leaf straps http://i885.photobucket.com/albums/a...ps18eb0c03.jpg http://i885.photobucket.com/albums/a...psdfaa554e.jpg And had to make a custom aching tool...with adjustable stop. http://i885.photobucket.com/albums/a...psf557272e.jpg FYI, McMaster-Carr sells a bunch of thicknesses and widths of 5160 spring stock. As long as you use sharp drills bits, keep it cool and use lots of lube, this stuff drills great. |
nice work....

Nice work man! Just curious on how you figure out the spring rate? I've got a set of Maeco springs that are rated at 300lbs and would like to reduce them.
Looking forward to seeing the car at Thunderhill. :thumbsup: Dan |
In all the years I've been doing this..... I've never seen a guy willing (or able) to arch his own springs. I bow in your direction.
Looks really good Craig! |
More pics of the roll bar please... And kudos for the home grown leaf spring mods, nice work.

This is a great build. It's amazing what you can build when no one makes parts for your car and you have more time than money. :lol:
|
nice work, love this build!
|
Subbing to what is one of the most creative builds on the internet IMO.
I've got a '95 Ranger as a daily/project and aftermarket parts availability is limited at best. After seeing some of the creative stuff in this thread, I am inspired to make the parts I'd like to have. Keep at it. |
Thanks for all the kind words everyone!

I use a combination of an excel sheet and this online calculator: http://www.auto-ware.com/calcs/leaf.htm Leaf are a little funny because of all the 3rd and 4th order effects of friction between the leafs and when they start twisting with body roll (which are nearly impossible to calculate). I didn't actually measure the rates, so everything is approximate. In college we messed around a bunch mixing and matching leaf packs for 4X4's and hot rods. The most important thing if you start modifying them is to keep the stagger between the ends of the leafs nearly evenly spaced. If you stack them too close together or put thicker leafs below thinner ones you can cause the spring to bend into an "S" which will can cause the main leaf to fail. Here are a few more roll bar pics: The main hoop and bars are 1.75 x .120 1018 DOM, the harness bar is 1.5 x .120 1018 DOM. Tabs are 7 gage (.177 thick steel). The car looked like a Dexter kill room but I did't get any overspary on my interior. http://i885.photobucket.com/albums/a...ps6e0ec2fd.jpg http://i885.photobucket.com/albums/a...psf6fa2c3b.jpg http://i885.photobucket.com/albums/a...ps26277bdf.jpg http://i885.photobucket.com/albums/a...ps2dbde4e0.jpg http://i885.photobucket.com/albums/a...ps080b3845.jpg http://i885.photobucket.com/albums/a...psacb0ef36.jpg Oh and this should be here in a few days: http://i885.photobucket.com/albums/a...ps7bfc5fdf.jpg |
