I know just how you feel, I'm not an idiot and don't like to be spoken to
like I am. It's the "lowest common denominator" syndrome again, some
watching are idiots so we treat everyone like that (although we that make
the programme aren't, naturally).
Instead of coming down to the lowest level why not make the idiots come up
to a reasonable level?
It's a constant beef with gardeners that the gardening programs seldom
mention the Latin names 'cause it puts the great unwashed off, yet without
the Latin names nobody is sure which plant is being talked about as the
common names vary even within this small country. As an example of confusion
take "Geranium" for example, is it a hardy herbaceous plant or something
rather vibrant that won't last the frost and is used for summer bedding?

need more information.  Is it a screwed-on freewheel, or a cassette type
hub?

I wouldn't be surprised if parts are not available, especially if Shimano
are involved.

Most bikes now have the freewheel built into the hub and a splined sprocket
carrier.  Older ones have a threaded hub and the freewheel plus sprockets is
screwed on.

Austin,

Do you have any experience with making recumbent frames?  I want to
price up some options, and wondered if you had a ball park figure for a
long wheelbase under seat steering job.

Ta,
