I looked through the scrap yard today and found two motors with
gear reductions that might work well for that. They were from
battery powered wheel chairs. They work, but are noisy. They have
a lever to disconnect the drive.

So maybe you could check with medical supply / repair places and
find something in their scrap that would work well.

What on earth is wrong with a normal wiper motor ? I have now
built
two and they work great ! Tumbler reverse, centre off and variable
speed.

I have a couple of wiper motors , but the worm gear is messed up
in both .


Yes they can get damaged when someone drags the wiper blade across the
windscreen. Just dump them or use them for something else. My local
scrap yard often gets vehicles in for disposal. Often the scrap man
will let you go in and take off any parts that you might want. Quite
rare at the moment but electric window winders are good too !
