Wasn't sure where to locate this, so as it will be 95% Metal, here's as good 'a' place as any.
Wanted to use the spare Villiers Mk2 Midget Engine I am rebuilding to power something stationary?, but will also need to have additional cooling.
I've been thinking about what I already have laying around in parts n materials I may need and started digging them out from various storage places.
Blowing the Cobwebs from my memory, I recalled back in the early 90s salvaging some parts from a 1948 Ransomes Simms & Jeffries Lawnmower, namely 2 hefty brass bearings in Plates that carry a heavy lump of (rusty) cast iron that acted as a PTO Clutch, rpm increase Gear Box and stored a lot of inertia.
The Mower itself was way past fixing up. Shame, as it had a large Starter Hand Crank, the likes of which I have never seen anywhere since. Anyway, I managed to recall where they were.
There's 2 remote Screw Capped Oilers, an old Line Shaft Bearing block (5/8" bore) with Brass Screw Down Greasers. Length of Box section Steel and 15/16" AF high Carbon Steel.
Also dug out some stubs of 1" and 5/8" AF Brass from my Garage Door Counter weights which turned out to carry several other useful bits.
Previous owner/resident of my property (60s/70s) must have been a Turner judging by the very dusty tarnished evidence-
The inside of this PTO Clutch is similar to a Diff which spins freely when drive is not engaged. A large Brake Band clamps the outer surface and the planet gears inside transfer the drive to the opposite shaft at a 5:1 increase in RPM. I plan for it to act as a speed reduction unit and PTO Clutch.
Condition inside is fairly good, considering there was water amongst the old grease.
I need to make new heavy bushings, fit new bolts and machine the outer friction face which is pitted, but still has the 'Witness' and number marks Stamped in by the guy who first assembled/finished it-
.
My main intention on this project is to refresh my limited familiarity with Lathe and metalwork practices on a fair amount of old Brass, Copper, Bronze and Steel parts. I'll be using BSF, Whitworth and BSP thread forms , and I won't be in any particular hurry to finish it, so please bear with me, as even I don't know what it is to look like yet! .
