Good stuff mate - keep it coming

[symes]

maybe if you modify the upright-and move steering bar up - I see it is mounted just above spindle height-maybe if you mounted higher-that might help

[lozzzzzz]

Yeah it does seem to be all about the steering arm height, but it seems I can do just that by altering the caster.  I did these little diagrams for the Scimitar forum so I'll put them here too. 

First is just what I need to do to get round having a ball joint, the second is the effect of altering caster

[symes]

ideally you want steering rod at same angle as wishbones-also is rack in line with track end-if you looked down at it? or is it further forward-if so -that wont help-and what angle castor are you running-on hotrod chassis I find 6 degrees fine-but that is beam front end-

[lozzzzzz]

Its all standard now, as Reliant intended! The Caster is 11 degree (also now as reliant intended)  I'm getting close to having as it should be now

[symes]

ah good-at least you got factory settings for start-that sure helps

If you want to beat the Ford Capri at Santa Pod, you need to fit one of these v6's into your Scimitar.

That looks very serious!!!!   I would quite like one please

[lozzzzzz]

Oh right some decent progress today

I tried making up some spacers on the lathe, but ruined the last good edge of the last carbide tip and ruined the thing I was making



Then I asked someone at work to do it for me and he made some up really fast


Hopefully you can see, there is a tapped hole in each side of the block, the tread in the steering arm has been drilled out so with the offset of the hols in the block the steering arm is up at an angle. 



Now, the bump steer is gone   I'm waiting with baited breath to see how it feels (the spring rates are still unchanged so could be well out), but hopefully it'll behave a bit better. 

I'm hoping to get that lot painted up and properly fitted tomorrow. 

More to come

What did that poor lathe tool ever do to you, Lozz..

[lozzzzzz]

Well it let me down by not taking 1cm chunks out at a time, is that really too much to ask



Today, I got it all ready for paint and put on lots of stone chip, but first I bent and welded a spanner to get at one of the PAS unions.  They've all been nipped up so hopefully will stop leaking. 


Its all back in place now.


Hopefully tomorrow I'll get it all tracked and.... camber'd!  then start on the exhaust or intercom, depends what arrives first.

Got lots done today. 

Got all the suspension back together, set ride height, checked camber, added a shim, checked camber, did tracking, set ride height again, checked tracking, made another adjustment, drove it, made another adjustment to tracking (to get steering wheel in right place) set (*******) ride height (again) checked camber (out on one side), (you've got to be joking) removed the (*******) shim.  Its getting there, I've got to check the tracking again as the shim removal will have put it out.  To give some kind of an explanation, I can't leave it "close" to what it should I have to get it completely right. 

On another note, I got some cool bits through today, I got an Autocom Active-7-Smart as suggested by Kevin, and made up some ear defender type headsets.  It works a treat, I'm pretty happy with them   Thanks a lot for the suggestion Kevin, they seem spot on for the job!



I'm hopefully tackling the 2100rpm exhaust drone tomorrow. 

More to come

[lozzzzzz]

I thought I'd take a slightly better photo of the intercom thingy which is working well


On the exhaust front, I thought I'd make a 1.4 wavelength resonator pipe for each side, but the materials came to quite a bit of money so being a skin flint, I thought I'd try a balance pipe.  The theory being that the two pipes should be completely out of phase and perhaps have a cancelling effect (fingers crossed).  Here are a few pics:





And guess what......






After all that work........





It made no difference, there is still a 2100 "Drone Zone" perhaps its 2% quieter or perhaps its in my head, or perhaps my hearing is gradually getting damaged.  Either way, I'll be ripping back off and trying the more expensive 1/4 wavelength resonator pipe option soon

More to come

I completely forgot to say, the alterations to the front suspension have worked really well, I'm very pleased.  The measured bump steer seems to completely agree with how the car feels.  This has now highlighted the next weak link in the suspension. 

The rear axle seems to spend a lot of time in the air when going over very rough patches of road, the back seems to step out a bit when on the power in a corner.  I think this is a combination of things really and just needs correctly setting up.  But it doesn't help that the axle is even heavier now, the disc conversion probably weighs more than the drums and the Quaife Differential definitely weighs quite a bit more than the open diff, on top of that the spring rates could be way out, calculating those is next on the list, and the I think I might have got the dampers turned up too much delaying the axles return to the road on rebound. 

More to come on that lot. 

[lozzzzzz]

I've experimented with side exit exhausts.  I'm not mad keen on the look, but I think it looks alright if its done well.  My thinking here was that it would alter the length of the pipes and therefore raise the natural frequency right up the rev range where it wouldn't be annoying in traffic.  But there was no room for the second silencer, it was far to exposed and will hit speed bumps.  I tried without it, but its ridiculously loud at all RPMs then.  So I binned the idea and shall simply be living it for a while.  After driving it round a little more with balance pipe on, I think it has made a difference, it wasn't just me hearing things, the resonance is a little less.  I wonder now whether its to do with the natural frequency of the cab!!?!?

I got the Intercom into the dash yesterday, by recycling a Peugeot Stereo.  I reduced the depth of the box, and put a new fascia on it as you can see in the pictures. 







Its not perfect (but that's in keeping with the rest of the car )

I'm off down the garage to continue the road trip preparations.
