Right, plan B !
So the preliminary experiment with the de L type mix proved just how stiff the pre-cured mix is, and there was no way that sort of recipe would flow into the space I want it to, only by having an epoxy ratio of about 30%.:tired:
This would leave the upper sections of this part too 'ify', so on to plan B - cast plaster of paris into the mold, making a male cast, then two female casts from that.
Mount the two in a cylinder, and spin cast the parts as per the plan for all other parts of the machine base.
Checked out the proper recipe for the P of P, mixed it up, and poured.
OK, I thought it was too stiff. It went off half way through the pour.(chair)
So onto plan C.
I shall build an actual part from scratch, probably from wood and 'car-body filler', and carve it to fit the router body. Take two casts from that using the spin casting pipe as the container.
Sounds a complex procedure, but bear in mind that my mold pipe, spinning at about 1500rpm, is subjecting the mold material to about 80G for 5 minutes, before it slows down for the normal curing period of the resin.
Onwards and upwards.

It's like doing jigsaw puzzles in the dark.
Enjoy today's problems, for tomorrow's may be worse.
