Matt Seabrook Posted March 14, 2011 Author Posted March 14, 2011 Had to stop for a moment work commitments have put a hold on things. Will hope to start back again soon. Quote

Matt Seabrook Posted March 19, 2011 Author Posted March 19, 2011 Matt, what type of steering angle sensor you planning on; string pot or just rotary Potntiometer? I have a string pot for mine and the stearing column 'straightness' doesn't really matter. I have put a pulley on my column so that it makes it more accurate; Right I have found a couple of hours to have another little play. Following on from Fraser's recommendation to fit a steering angle sensor I have made a pulley to improve the accuracy of the sensor. This will double the diameter of the steering column and make the string pot move more for the same steering input. I have made it this size before anybody asks as I had a peace of aluminium in my workshop aprox 44mm in diameter. I started off by squering the ends off in the lathe and boring a 19.2mm hole through the blank. I then turned down one end ready for a grub screw to secure it. Then I cut a groove in the other end to make a pulley for the cable. I then drilled a hole in the thin end and fitted a steel threaded insert held in with strong lock tight as the alloy is not great to have to tighten up against. It just needed a grub screw now to be able to lock it to the column. Quote
nikpro Posted March 19, 2011 Posted March 19, 2011 Nice work Matt, the only thing I would suggest is where the 'string' runs in the pulley it needs to be a 'V' shape so you get the same 'overlap' on string as the pulley turns. I know I've not explained myself very well but if the string doesn't wind on & off each time you rurn the wheel in exactly the same manner you will get slightly different readings. Quote
hilux Posted March 20, 2011 Posted March 20, 2011 QUOTE That's the way it is John trying to hold a tiny peace of steel with welding gauntlets does not alway make it easy to get nice welds. You may be aware so hope you dont mind but I use welding magnets. Invaluable for fiddly bits. Looking forward to the continuing story. Quote
Darrell O'Neill Posted March 20, 2011 Posted March 20, 2011 Great work Matt, Im going to have to pop in and take a look at progress sometime... Ok, Im going to prove my ignorance and thickness here, but what does and steering sensor do, and why do you need/want one? Quote
Matt Seabrook Posted March 20, 2011 Author Posted March 20, 2011 Hi mate a steering angle sensor connects to the data logger and it records steering input. Once calibrated you can tell when you get under steer or over steer which helps tuning the chassis and hopefully will make my car handle better. Quote

Yep have seen them before the peace I was trying to weld was only 25x20mm and that was the big bit. Cheers anyway Paul Quote

Yep thought about that Fraser. I am going to cut a slot in the front face of the pulley and drill and thread the front face to secure the cable that way then I will run the cable at a very slight angle which should allow the cable to lay flat on the pulley and not over lap it self. Well that's the theory Quote

Matt Seabrook Posted May 2, 2011 Author Posted May 2, 2011 Gathering more bits John. Will get back to it again soon. Quote
Matt Seabrook Posted May 16, 2011 Author Posted May 16, 2011 Right its time to get the engine sized up to get the engine mounts welded in. With the engine in place its too tight on the the clutch master cylinder so some more fettling will be required. Still must get on with putting some more hours in to looking at it. I think I will paint the chassis rather than powder coat as if I want to alter anything I can and touch up the paint work. If I powder coat it this will not be possible. Has anybody tried this? Quote
Norman Verona Posted May 16, 2011 Posted May 16, 2011 Matt, the secret of chassis paint is that it's soft. When stone chips hit it at 90 mph it doesn't chip it just absorbs. A good chassis paint will last years and is easy to paint over when it does get damaged (rare). However it doesn't look sexy. Quote
Matt Seabrook Posted May 16, 2011 Author Posted May 16, 2011 Thanks Norm sexy looking is for the rest of the car mate. The chassis has to do its job. Just dont want something I have to keep fussing with. Quote
