a new project for fabroman
a few months ago there was talk of a diy valve spring compressor
i said i had seen a good one at our training college
but i never had a reason to make one till now
its built very much like the bead breaker
and works very much the same
it was made to compress the springs on a cat 3512 head so this one is way too big for what u want
this one is welded to the bench due to the force involved
and it was roughly knocked up out of scrap steel so it requires tidying up and slight modifications to suit small engines
the one at TAFE was on a stand that allowed you to move it
we tryed the ones that look like a G clamp but the issues with those is the lack of shock u can apply so the collets release from their taper, then stuff starts bending/breaking.
we tryed both manual and pneumatic ones
originally it pivoted at the handle and at the actual press plate
as is clear we welded it because it was clear it was a bad idea to pivot it there
the press is made of a washer welded inside a piece of pipe
there is a second piece of 4ft pipe that fits inside the handle as an extension
u can hang a counter weight off the end so u have two hands to insert the collets
we used a 20kg D shackle
its useful if u have a pen magnet to remove the collets and a tiny srew driver to install them
gotta add that it is important the u dont put your head over the handle, there is alot of stored energy in the springs and the handle is a large metal bar
and dont put your fingers inside the press plate for the same reason

You mean for me to recreate smaller scale?
