You could try joining the local U3A and setting up a Model Engineering Group
It may not succeed, Don't be disappointed if it does not get off the ground..
What people say that they want, does not mean that they will actually do it when the question is put.
Our local U3A publicised a proposal for a Model Making Group.
Because I showed a mild interest, suddenly I was posted as Group Leader., and spoke at a virtual Activities Day.
As a PSME member, it seemed a good idea to affilkiate the new Group, and become members, It seemed ideal, since a venue and a programme already existed. Everything seemed to be in place.
(It had worked very well with the Peterborough Engineering Society, which has now become a part of U3A )
Five attended for a few meetings, and then four "resigned", and the other never made any further contact.
As might be imagined, the Group no linger "exists".
Sad, but these things happen.
