Scaffolding poles + old VW bits + Rotary engine....

Engine and 'box out tonight, 6 pieces of teeth floating around in the diff...whoops.
Looks like fatigue started it off, but flex in the diff from impacts finished it - looking at the shape and angle of the teeth that are missing, perhaps we can make up something to fit behind the crownwheel near the pinion with a bearing or something on just for the crownwheel to ride on when it flexes?
Be a good time for that limited slip diff though, anyone got any money they need to write off through tax as advertising costs?

Engine out, gearbox apart, 5th gear synchro/selector was worn just enough to move ~1mm on the shaft and jam the whole selector mechanism.
Put a 45* bevel on the edges of the selector to help if anything similar happens in future, and 5th gear/selector and it's fork are on the bench looking lonely
Gearbox back together, engine and box back in, radiators back on, fluids refilled and bled, test driven, works beautifully.
4-speed gearbox now, it's lighter, might go faster

Right, after a very rough event at Kirton today, we've managed to claw a couple of places back and end the year 8th overall in the Championship, albeit after battering the skid pans to death, punching two holes in the floor, cracking the windscreen on a hard landing and hitting the engine skid pan hard enough to dent it the whole way across and put a dent in the sump too.
Oops.
This stand-in engine was feeling decidedly unhappy towards the end of the day too tbh!
Writeup later!

Yes, I know, the mudguard is miles out and the wheels are about as round as a 50 pence piece - don't worry, making new ones, gotta move the mudguard as we're making new damper mounting towers too, improve the motion ratio and change the progression curve. Gives you an idea of how much travel there is though, that's not quite full compression - it's got another half an inch or so.
The things we go through in the name of money saving...couldn't really stretch the winter budget to a set of longer 10" stroke front dampers to match the arms, so we're having to trying and make the old 8" units do the job, doesn't do the motion ratios any favours, but needs must:
Damper goes the other side of the bracket but the old shock tower was in the way, I've had the angle grinder out since and there's a lot of front steelwork sat on the floor now though
Best get on with making the real replacement arms properly now though!

Right, Ed's finished welding the jigs up tonight so should be able to knock the proper T45 tubular arms out in the next couple of days, got a few bits of chopping and tweaking on the chassis we weren't expecting just to add a little clearance around the tie-rods, and possibly move the rack a little more, but it's almost there, just waiting on some spacers/fitting for the new steering arms.
In other news, engine should be back together just in time for christmas, it's had a bit of light port work to boot as well, see what Santa brings when you've been good...
Hopefully should get chance for a run around the yard and lane after christmas just to give it a quick check over (I'll get some video this time, I promise!), then it's back to ordering yet more springs, damper oil and valve shims/stacks, as the whole lot needs re-valving and re-springing again, doh.
And another 6 wheel rims to make and weld up too, bit more offset now the track is wider.
Once that little lot is sorted, we'll start on the rear suspension!

New upper mounts in progress for the damper, didn't really want to put a kink in the arms (need to be as stiff as possible) but couldn't clear the damper when it's fully compressed without, good enough anyway, another tie-rod to go down the chassis toward the rear mudguard mount too - may as well - but it's stiff enough without tbh:
Don't worry, it's not getting heavier, it's all thin-wall T45 tube, lighter than it looks!
Certainly lighter than the plate tower that was there before anyway.
