Thanks. Ive got that pic too but its finding the tool thats the problem. Might be difficult to make.

easy to make.....

lathe some round stock down to the ID of the liner- a clearance tolerance of a few thou lathe the head down a fair bit more This is your guide post(the next bit slides onto this so aim for the OD that fits its ID)

Lathe some pipe stock down to the same OD as the sleeve you wish to install - 5 thou This is your driver

to get the angle.....

Remove one of the liners ,cut the top 3/4 off and then cut a slit down the side Install this at the bottom of the bore (this is your alignment shimming collar)

slide the guide post in place and align the bottom into the shimming collar you just put in slide The driver down , Take an observed guess at the angle then cut and clean the face.

Remove the lot, bearing blue the face of a liner in an adjacent pot, Install all the tooling again in the blued liner, observe the face of the driver for even bluing and adjust as required.

remove the guide post and lathe the top end down enough to allow the driver to press the sleeve all the way into the bore (typically 1/4 of the height of the top sleeve mount is enough)

When using this to install your new liner install the alignment collar in the bottom so that the top of the collar is about halfway up the lower sleeve mount in the block. slide the guide post into place and wedge it with a couple of strips of shimming matrial inside the alignment collar. Slide the new sleeve in place and drive it home with the driver.

Once it has started to move past the top of the bottom sleeve mount remove the alignment collar and then continue to drive it home.

Dave, these liners dont have a flat face. See the pic. One would have to have the adaptor to match the curves or the uneven pressure on the liner may break it.
There is no liner in there to use either. Its dry and has to be bored to suit.

My bad missed a step in my haste to write it up for you, Relevent section in blue below missing step in red

Theres also a couple of obvious omissions in there but if you're at the stage of doing liners in an engine you should be able to spot the shortfalls of the writing and run with the intent.

(no, its not my best set of instructions ever so no, I wont be offended if they dont make complete sense and you need them rewritten)

And I've just re-read your post, you get it easy.

when it comes to the stages of machining.....

Machine an aligning plate that is the ID of the lower liner support, give it a lick with some sand paper (you want it not quite press fit, it should sit there with a coating of light oil/coolant as adhesive) then bore the center to make a post hole for the guide post
machine your guide post to the ID-5 thou of the liners you have then cut the step to support the driver and a post for the lower aligner
Machine the OD of the driver to id-5 thou of the liner supports
stand the driver on its end, drop the guide post in then drop the liner over the guide post, wrap it tightly in cardboard then trace out the face of the liner.
remove the liner and the cardboard, cut out the cardboard. Replace it onto the driver and mark the driver.
Cut and clean the driver to suit replacing it onto the guide post and using a blued liner to check your work.

Ally is a great medium for doing this with, if you are concerned with the post changing position too much after the guide post drives the aligner out of you can either make one up in the form of a C as per the previous post with something of similar wall thickness to support the post but realisitcally once the liner is in the first support it should just keep working its way down squarely if you apply the pressure evenly.

If you want to go old school with it, just make the driver up, 5 thou undersize of the liner supports, dome the top of it and beat it in with a hammer.

Keith,
What about making a pattern and casting it in aluminium? I seem to recall that you have a lathe and a furnace,
