This week is the beam rebuilding week ;D Just set up the milling machine to dimple the torsion bars (doing them in the morning) just ground a 12mm bit to exactly 45 degrees to match the grub screws, so if anybody needs one, you can borrow it for a kiss ....or a pint if yer a girl ;D Just fitted the refurbed steering arm and steering damper with the special bracket to match the 4" narrower beam. Fitting the cut down and modified torsion bars tomorrow (the paint on the torsion arms is drying as we speak) Stripped and refurbed the calipers and they are ready to rebuild when my seal kits come tomorrow. Cut down and refurbed the adjustable track rods for the steering (don't believe Creative Engineering when they say take 15mm off each end, you need to take 22mm off each end AND cut down the thread on the track rod ends by the same amount) And YES, I am am rebuilding it in the Dining Room ;D ;D

Nah. He's not home yet, coming home on the last weekend of the month but considering he has no front beam on, and no rear suspension and he is 150 miles away, the pressure is on ! And the trailer is booked

Well, ive had a busy 3 days but it is soooooo slow to do work on it. I welded the ends of the torsion bars and then centre drilled the new dimple centres (4 inches narrower than before) Then I ground a HSS drill bit to exactly 45 degrees to match the grub screws and then dimpled the torsion bars to the correct depth. Then I cut the end off the torsion bars and deburred them. Once I had started cleaning up the torsion arms and repainting them, I started re-assembling the beam. The torsion bars were a bitch to get through the adjusters but after a lot of blood sweat tears and swearing I managed it. Here it is (still on the dining room floor I am afraid), 2 torsion arms in and fixed, new polymer bearings and new boots on the balljoints. You can just see a rebuilt brake caliper on the floor ready to fit to the discs. You can just see the ends of the lower torsion bars sticking out of the beam on the left hand side. I will post some pickys of Harry at the weekend with his back suspension finished (going on friday to do that) ;D ;D

Busy day today. Got the refurbed back brakes on and spring plates and then decided to heavily notch them Then took em off, notched em and put em back 2 splines dropped. Eventually managed to get the wheels on (good old scaff bar ;D) and dropped him to the floor. Only to realise that 2 splines is not enough, he needs to go to three. Didn't have time to re do it all, so he is coming home in two weeks with a bit of a rake ;D ;D Wot do you think ?

Well done Dodgy, i always appreciate the work people put into these old rides. Those springplates have lost alot of meat!! Looking good, think it needs a shitty rack on the front with a rusty wheel barrow strapped to it ;D

Yeh, I was a bit concerned about how much I needed to take off the spring plates to get the clearance. I had seen more severely butchered ones before but I still did the calculations.
I based it on each spring plate taking half a ton and the suspension theoretically could accelerate at 30 metres per second squared (3g) that gives a total bending moment of 1500kg or 150000 Newtons given the fact that the springplate is stopped from twisting by both the torsion bar and the swing arm, the only calculation I had to do was the bending moment in a simple cantilever.
Given the 2nd moment of area for the spring plate for the x axis is :
I{x}=bh^3/12
Where b is the width and h is the height, I{x} came out at 364500 mm^4
Based on this, the spring plate as it is can take 764000 Newtons bending and 1548000 newtons in shear, so I should be OK as long as I don't hit speed bumps at 50mph or put 2 tonnes of sand in the back ;D

My method is a little less complex...
Anglegrinder in right hand, spring plate in vice..."hmmm bout there" and start cutting. ;D

It's been a while, I've been busy but here is Harry Update. HE"S BACK IN NORTHAMPTON. I've been thrown out by my Dad !!! Only joking ! My dad is great and I love him (and actually he loves Harry ;D ;D) Thanks dad for letting me keep him in Yorkshire and let me stay while I sweated and bled in his resto ! Here is Harry lowered, narrowed, re-braked and looking GORGEOUS. Notice the big bearded Yorkshire farmer in the background...That's my dad, that is ;D ;D This is what he looks like underneath. (Harry....not my dad !) I can't get him any lower at the back yet (Harry....not my dad !) cos I need to grind off the bump stop brackets, then he is going 3 splines at the back (he is 2 at the mo.) I will post pics when he is 3 splines. Next job is sort out the engine (clean degrease tune and lick (probably in that order) then I am considering dropped spindles and tubbed arches at the front, I reckon he can go another 1.5 inches before the beam hits.
