not made a contribution lately but got a couple of days before the bits arrive for the work on nicks chim so been machining the sockets for the swivel bearings on the a arms, they tend to warp slightly when welding plus made a start on machining the split clamps for the steering rack hopefully finish tomorrow although got to make a boring bar for the mill first.

sounds like a plan


john

[Engineer1949]

well i am back again after becoming a civil engineer and at last finishing my wedge back on the cerb started by starting the machining for the rear arb bearings but should be lots coming in the next few weeks.


john

[Engineer1949]

Yes johns wedge rebuild on about page ten


John

[Engineer1949]

well back on track finished the mounting brackets for the arb also now fabricated the mountings on the chassis for them and started machining the ends of the bar itself which will be sweated into the tube to create solid ends for the link arms to fit into i have built up both rear suspensions to get the length of the drive shafts needed plus have made and fitted the diff carriers to the chassis so the rear end is nearly complete

fair bit more done, started on the front arb and have finished fitting the support brackets, also finished fitting the steering rack had to do a chassis mod to get the pinion of the rack exactly where it is needed to avoid any bump steer etc.all getting very snug up front, i have sourced the material for the arb levers and cut to lenght they are now away being taper turned as my old capstan cant taper turn so should have them back next week.

busy couple of days managed to get the seat mounting sorted and the seat in the car very snug, nicks coming monday for a fitting of the pedal box and steering column which will then entertain me for a while sorting there mountings etc.flikrs up the wall again will post pics when it sorts itself out.

john

[Engineer1949]

got the seat mountings all fitted and had nick test it so have now got the pedal box mounted on the temporary floor and sorted the steering column run plus turned up the tapered arms for the arb and turned up the link tubes for the rose joint to arb arms and fitted to the car to check nothing fouls with full suspension movement all seems good also turned up three 7/16unf slugs and welded them into the chassis for the harness mounts not done a terrific amount to the car with all the work and testing with the ginetta and work to update and road oriantate the chim

the arb tubes are hydraulic high pressure tube in imperial size 1 1/2 front 1 1/4 rear with solid slugs fitted in the ends for the bearings to run on and take the arms

john

cant believe it was feburary when i last did anything to the cerb but over the last few days i have had a chance to get at it again, sorted some stuff on the chassis and now have started on the body fitment and modifications also got the pedal box mounting sorted.

been to long since i did anything much to the car but getting on now the rebuilds for this year are done, started by removing the door sills to about an inch above the hip joint this is to allow the exhausts to run in newly built sills one each side so been making the plug for the tops of the sills the side and underneath will be removable to gain access to the exhaust, also started in between waiting for stuff to harden on the plug for the n/s/f wing as all four wings have got to be remade to accomodate the extra track and larger wheels plus getting on with the steering column made up the first part from rack to support bearing tube all nicely tigged onto the splines with a nice birdmouth shape for greater strength,gearbox has been changed to a t56 magnum 6 speed got to do a new mounting for that today.

no i am doing all the work myself but having spent years in the marine industry on the broads not to much of a problem.

john

[Engineer1949]

todays update, lots more done on the wing plug, first part of the steering column installed and the gearbox mount fitted the mount was easier than i thought just had to remove material from the old one as the new box is longer so further back in the chassis.
