Widdershins, First Outing

Artemisia said:

In fact, there is precious little space on this thing, it's even worse
than an upright. Apparently one isn't allowed to put anything on the
handlebars because it could perturb steering.

The main problem with lights on underseat bars would be (a) they
restrict the steering lock or (b) will be invisible to points they need
to be seen from.

In either case you can discover whether they're problems with a bit of
experimentation. Put the lights on, see if you can still steer
effectively (you don't even have to be moving). Look at the trike from
all angles at the front and see if you can see them well (preferably
with someone sat in the seat, so you can see if the rider obscures
them). if the answer to both is yes then they'll be fine, otherwise
it's back to the drawing board.

For a Space Grip source another boom with a derailleur post (Phil Cook
actually suggested asking for one specifically for this job back in
August when you were asking where the lights might go...).

You probably could improvise something with a Space Grip and hose
clip around the boom, but doing it neatly would be harder. The boom
doesn't by any chance have a bottle cage mount you aren't using?

HP Vel helpfully[1] put one on... the derailleur post!

Pete.

[1] well, not very helpful actually, even if you (a) have a DP and (b)
want a drink.

Quoted message said:

Carol Hague and Rob at Westcountry Recumbents had a lighting system on
one of their trikes with two lights by the sides of the seat. They
were on the handlebars, I think. That't the sort of thing I have in
mind.

I tried mounting EL530s on the mudguard mounts on my XXL, but gave up after
one winter ride as water, mud and Skog(tm) were continually thrown forward
by the front tyres and thereafter fetched up on the lenses of the lights.
All my lighting is now mounted on the front derailleur post which, if you
haven't got one, is this much use: 0.

HPV don't fit a derailleur post unless you request it, or have a bike with
front derailleur.

A friend found this out when his Grasshopper arrived and he wanted to add
lights. He'd assumed a DP would be fitted as the test-ride bike had one (due
to front derailleur), but he ordered a bike with a SRAM 3x8 rear
transmission.

I think he put a big band around the boom, and fixed stuff to that.

Helpful if you have a DP and want a light mount like this though:
http://www.ice.hpv.co.uk/custom_trikes/accessories.htm#frontlightmount
And on a touring machine you might well want more bottles than your
easily accessible on the move one, say for your stove fuel. Obviously
having something accessible as well would be even more helpful.
But neither of those are relevent here :-(

I couldn't see a boom mounted one on photos, but thought it was worth
asking just in case.

On the Streetmachine they've provided another one on the underside of
the main frame tube, which is also bloody awkward to get at :-(

I just put drink bottles in the lowrider pannier pockets, or put a
pannier on the back rack backwards (as at
http://www.personal.dundee.ac.uk/~pjclinch/smgt-meik.jpg)

ROTFL 🙂 Nice one, Tim

IMHO whatever is going to be 'tricky', as the boom is HPV's squashed
oval shape at the front, with AFAIK just one bolt hole at the top
rearward of the BB and one underneath 🙁
Maybe an 'L' shaped bracket with a handlebar diameter bobbin attached
to it might work - could have one on top and one underneath (if an
EL530 'works' upside down)? - don't know anything off-the-shelf that
would do though....

http://www.hpvelotechnik.com/images/presse/sco_fx_links_dreirad.jpg
and other pics on the HPV site, you are supposed to use the mounting
point on the underside of the boom (under the bottom bracket) with a
B&M type dynamo light mount 🙁
This would seem to be a major pain in the bum, as I'm not aware of any
commercial adaptors that you could use to mount your 530's from there,
and IMHO a single screw attachment would not be strong / stiff enough
for the weight of two (or even one) decent battery lights. And you do
really want the lights well forward to minimise foot flash.

How about fitting an extension to the boom using the existing lamp
bracket, and mounting the lights on that? That would put them away from
any obstruction, with a reasonable range of location, and removeable
with a single bolt or clevis pin (although it might need a velcro strap
around the boom too). You could probably reverse it to carry the lights
inboard when they weren't being used, or if the lights were easily
reversible use it as an alternative mounting position.

Widdershins is a wonderful word. I haven't seen anywhere except in the book
"Dahlgren (Samuel Delaney)", and the subject of the thread. Of course I had
to check Google and there are lots of references to widdershins, but when I
read Dahlgre it would be several years until I got my first computer and
more years until the invention of Google.

I can't remember it in that book, but then there is a lot in there that
was difficult to figure out. I'm not sure I ever understood it all.

Check this out as a possible means to mount your two lights:
