Anybody got photos/drawings/sketches of the late Ruby/Pearl door card oval carpet?
Is it just stuck to the door card vinyl or is it inserted through?
Also it would be useful to have info how door pocket fixed to the door card.
As you will gather just doing some restorative work on the cockpit of our Pearl!

Crankshaft advice |

A little collective advice needed.
A friend, who has run a Big 7 for years, has seen the light and bought a project Baby 7. The engine was apparently rebuilt but ran very noisily. We stripped it down and found that a new crankshaft had been installed but there were many problems with the engine assembly, including oval, oversize small end holes in the original, Austin rods, enlarged valves fitted without relieving the head, high lift cam without shortening the bronze cam follower guides, massive timing gear backlash etc.
The engine had been run, maybe 500 - 1000 miles but had obviously shown problems.
My friend removed the big end caps and has found that the hardening on one of the crank pins appears to have failed and the pin is pitted and slightly scored. This might be due to corrosion; the corresponding metalling appears OK.
So, the question is: Can we regrind the crank -0.010 and run it without the hardened layer? Has anyone done this? Could it be ground and re-nitrided?
The crank might be a Phoenix (it isn't marked as such) or might be one of Tony Betts.
Any thoughts, Ladies and Gentlemen?

Ulster Rep Rebuild - Gearbox release bearing pressing on clutch arms |
Posted by: Ned - 08-01-2025, 01:22 AM - Forum: Forum chat...

Hello everyone, my dad Erich and I are on the middle of an Ulster Rep rebuild, and we've run into an issue mounting the gearbox to the engine.
With the gearbox fully seated, the clutch bearing in the gearbox is pressing down on the clutch arms just enough to cause it to slip, without depressing the clutch pedal.
It seems like the release bearing we have won't fully seat onto the assembly, as there is a bit of a gap between the base of the assembly and the top of the bearing cage, even after hammering it on.
This setup looks to be a later type clutch release, with our setup using a leaf spring instead of the coil spring to pull the bearing back.
The clutch assembly is also a later type, with mousetrap springs and roller surfaces on the clutch arms, but no blind spline on the input shaft.
Since we are using a 3 speed crash box with the later type release, which was made to work with 4 speed gearboxes, we were wondering if the distance between the release bearing and the clutch arms could be widened in some way to avoid pressing into the clutch. Any help would be appreciated!
Cheers
Ned Volkstorf
