Anyone made their own transmission cradle???
Before I bust another gut (more accurately strain/damage shoulder muscle) has anyone made their own cradle?
I want it to fit on the trolley jack as I'm working underneath, car up on axle stands.
So far I'm thinking thick piece of oblong chequer plate with a stubby rod welded centrally underneath to locate in the jack head, slot and weld
four short pieces of 25mm SST horizontally to it then come up at
50 (?) degrees to approx. 150mm - job done.
Any pointers/plans/links/comments welcome.
Gearbox is MX5.
TIA.
Cheers, Pewe10
PS using SST as I have that in stock

I believe what you are proposing will be unstable, you need to remove the wheels on the Jack, weld on some extensions and fit with heavy duty casters.

the jack would prob get in the way and cause more trouble than it,s worth...better to find a robust mate to give you a hand

I bought a second hand motorbike lift for about £30, was perfect for getting the transmission out of the S-type.

Bit expensive to buy them new though.
If disfunction is a function, then I must be some kind of genius.

Just in case any-one is interested I made it from an oblong piece of checker plate about 150 x 300mm, drilled two holes around the centre and clamped
it the the jack head using an exhaust clamp.
Then welded six 25mm SST uprights, 3 per side about 50mm high to the plate, V notched at 90deg. at the top.
Welded horizontal SST along the length at either side into the V to help locate the box - job done.
This made life sooo much easier as all the weight was taken by the trolleyjack.
However the killer trick was using the angle guage under the sump and then on a suitable horizontal surface on the gearbox - once they were both
horizontal (needed a bit of packing under the g/box tailshaft and a bit of jacking at the front of the engine) it meant the box slid into the rear of
the engine like a rat up a drainpipe.
Now all I need is for the weather to turn fine and I'll be able to do all the fricking awkward bolts around the bell-housing etc. etc......

PS the cradle will also double as a motorcycle lift.
PPS anyone who wants dims. or pics please PM me.
