slngsht Posted May 15, 2007 Author Share Posted May 15, 2007 A couple more welds and this side will be standing on its own http://www.usa7s.com/aspnetforum/upload/171730213_CIMG1423.JPG http://www.usa7s.com/aspnetforum/upload/1157596177_CIMG1422.JPG http://www.usa7s.com/aspnetforum/upload/892748737_CIMG1421.JPG Link to comment Share on other sites More sharing options...
slngsht Posted May 15, 2007 Author Share Posted May 15, 2007 Well, she's standing on her own two feet... barely. The change in geometry of the front is significant. Before, the lever ratio for the spring was 1.1 (1" wheel travel = 1.1" spring pickup point travel), and the spring was almost upright. Now, the ratio is .82, and the spring is at about 45 degrees, so as you can see, my 225 lb spring is cranked all the way, and the car is still leaning to that side. I need about a 430 lb spring to have the equivalent of what I had. It was a tad stiff before, so I'll try 375 or 400 lb springs. The good news is, before, my shocks almost had no adjustment range... out of 1 - 15, by the time I got to 5 or 6, I might as well had a steel rod in there. Now I should have better adjustability there. http://www.usa7s.com/aspnetforum/upload/454505572_CIMG1424.JPG Link to comment Share on other sites More sharing options...
slngsht Posted May 16, 2007 Author Share Posted May 16, 2007 Well, it's time for a beer :cheers: Wheel is bolted up, and she's standing on her own. I did several drop tests by taking the car up, and releasing the jack. So far so good The Aarms for the other side are about half done. I have to order some more goodies from McMaster to take care of the steering, and should be good to go... probably another week or so. http://www.usa7s.com/aspnetforum/upload/1544620745_CIMG1428.JPG Link to comment Share on other sites More sharing options...

slngsht Posted May 18, 2007 Author Share Posted May 18, 2007 Still a long way to go, but most of the problems ahead of me are simple ones. Last night, I finished the other lower Aarm, and I still have 2 more welds for the other upper one. It sucks living in a development. Can't grind outside because of neighbors, can't grind in the garage because kids are sleeping just above :banghead: Steering tierods are the next big thing, and after that, I just have to adapt the brake line fittings, get the right length bolts, and align her.

slngsht Posted May 21, 2007 Author Share Posted May 21, 2007 Well, got to spend a couple more hours today, and got the tierods done. http://www.usa7s.com/aspnetforum/upload/1882300140_CIMG1435.JPG To get the approximate length of the tierod tubes, I wanted to doublecheck them on the car. As a quick and dirty cross check, I used a laser level (on the middle tire) to shine a beam on one of the grooves of the rear tire, and used that as a reference point to make sure the front wheel is reasonably straight. It's not good enough for alignment, but is accurate enough to make sure I have the right length tierod and adequate toe adjustment. http://www.usa7s.com/aspnetforum/upload/512215456_CIMG1433.JPG Although the car won't be done by this weekend, my goal is to take her for a test drive on Saturday.

slngsht Posted May 21, 2007 Author Share Posted May 21, 2007 what a frustrating night... went from parts store to parts store to try to find a way to adapt the brake line fittings. No luck :banghead: Link to comment Share on other sites More sharing options...
scannon Posted May 21, 2007 Share Posted May 21, 2007 what a frustrating night... went from parts store to parts store to try to find a way to adapt the brake line fittings. No luck :banghead: Not sure what you are trying to adapt but I found most parts stores have lengths of pre-made brake line with a fitting on each end. For my clutch line I needed to connect the Caterham master cylinder to the metric Mazda slave cylinder. I bought one line with metric flare nuts and one with British flare nuts. I cut off one end of each, moved a metric flare nut onto the British line and made a new flare. The metric end goes into an afertmarket Miata braided line and on to the Miata solid tubing the rest of the way to the slave cylinder.

slngsht Posted May 21, 2007 Author Share Posted May 21, 2007 I've done that before, and that's what I was hoping to find... but oddly enough I couldn't find any that fit either the old fitting, or the new one with the caliper. I was at a Carquest store earlier today that had the individual ones in his hand. I'll go back in tomorrow. Hopefully I can get something together. Advanced Auto stores are hopeless.

Robert O. Urfer Posted May 22, 2007 Share Posted May 22, 2007 Do you have an aeroquip store around? We actually have two custom hose shops around that mainly deal with heavy equipment but they are open to the public. Does this mean you will be selling your old braided stainless brake lines? I need them. I have the crappy rubber ones with springs around them and they are going to break any time now. Link to comment Share on other sites More sharing options...
slngsht Posted May 22, 2007 Author Share Posted May 22, 2007 You can have my braided one... I'm sure aeroquip is somewhere, but don't know where. I do know where Grainger is, so will be stopping there today. Link to comment Share on other sites More sharing options...
