60 quid each for THAT? You could make some for 60# a set, probably. Piece of
8" OD 4" ID 6061, from the friendly metal shop, parting cutter, and a drill
press (make a jig out of an old hub or a brake drum). I figure the
material's a hundred, canuck buck, plus a box of wheel studs and some drill
bits.
You would LOVE the standard co. lathe I've spent the last three hours on.
Nice to be able to fit a 12" diameter piece of 1/2" plate in the chuck with
room to spare. BTW - THREE jaw. The four jaw would probably allow you to
spin an entire engine block ;-)
I swear the only thing this lathe needs is a chrome smoke stack and
clearance lights. The shop lights dim when I throw this puppy in gear :-)
BTW, while on the subject of machining, I'm finishing up my graduation
project today and (big surprise) it's a rover thing.
I designed and build a fully hydraulic disc brake setup to replace the
transmission brake. It's a Wilwood Dynalite billet alum. alloy 4 pot caliper
with SS pistons, with all the brackets to mount it to the T case (no
modifications necessary) and there is a hose that extends up to a small
hydraulic pump with integral reservoir, with built in pressure relief.
Basically, two pumps of a lever and rover ain't moving - ever. The design
criteria for this thing is dry pavement (.9 frictional coeff.), dragging all
four wheels along the pavement (actually, right before that, static, not
kinetic for the anoraks), and with 3.54 gears (less reduction) and 36"
tires(moment arm, baby!), with a safety factor of 2+. I've got built in
shear pins on the rotor (haven't had time to cross drill it, maybe later on)
so the transfer case doesn't explode if ever I forget it's engaged and drop
the clutch in low range at 4500 rpms.
I get to try it out tonight!
