Hope you appreciate this?
I've done some research for you.
First up, generally, large rides are pretty well documented. They're noted and photographed and set in history. Exact dates and details may end up lost, but I've never heard of an entire ride go missing (though if it was missing from history, I wouldn't have heard of it :lol: ).
Even Switchbacks which only lasted a couple of years on a remote beach are documented.
So, looking at a purely documented history side - there's no evidence of there ever being a ride on the pier at Weston during that period. So right away, I'm afraid that I have to say that your Uncle is wrong about it, and certainly about the time frame concerned (a portable ride there for a short while
may slip under the net, but not a permanent structure.
So, the next step is to look at other documented proof. We know there is a documented Le Marcus Thompson Switchback are Birnbeck - so let's hunt for it.
Two postcards show the Switchback, in varying states of repair:

http://www.oldukphotos.com/graphics/Eng ... 00%27s.jpg
I suspect the latter one is a true reflection and the former is an idealistic view. The latter photo certainly seems to be the same kind of period (late Victorian/Early Edwardian), but there could be 20 years between both images. I'd say the absolute latest the latter image is is in the 20's.
By 1955, the Switchback is clearly gone:

So it's certainly not the Switchback on Birnbeck he's thinking of as it's gone by the 60's, and there's no photographic evidence of a ride on there any later.
So, that leaves the Grand Pier. Here we have a view of the Pier and promenade are in 1935:

No sign of a coaster there at all. So 1935 there is no coaster. Figure 8's were certainly being made at this time, but generally, coasters were only going into established parks. There isn't one on the sea front at Weston by this period (there's evidence of a small park during the late 1800's on the sea front, but it's gone by the 1920's).
So, no coaster in 1935.
Let's look later Lots of shots C1955... The photographs at this time are a little harder to get such a good over view, but we have these:
Grand Pier and the sands (this shot was taken at roughly the same place the old park stood in the 1800's):

Grand Pier Entrance from the right:

Clearly no sign of a coaster structure at all. It's worth noting that generally, coasters are well photographed if they're in a prominent place on the sea front. So the fact that out of 133 photos of WSM over 100 years of history, there are none opf a coaster - leads me to believe there wasn't one. Having said that, there's no photographs of the later coaster mentioned on RCDB either, but there isn't of the one at Trentham gardens - there are periods where images haven't surfaced yet as they're actually TOO recent.
Just to finish off, two shots of the marine lake area of WSM, just to make sure that we've covered anywhere that may also have had the coaster on the sea front:

There just isn't anything written, or photographed about it. The only thing it could possibly be is the coaster mentioned in passing on RCDB - this coaster indoors that they seem to have got wind of. This could have just been a small coaster, but it might also have just been a simple ride. If it was anything major, it would have a footnote somewhere - you'd certainly be able to see if a Figure 8 or any largish coaster was on the pier - the building would be quite notable.
So, I suspect that your Uncle has a slight mis-memory problem... It may have been a different resort he used to holiday at.
