Getting bits made (specifically a new tagalong bracket)

Anyone know anywhere Leeds/Ilkley way that could make a new bracket for
my tag-along - but specifically one that is about a foot long, as
opposed to only 4 inches long.

I have this plan to be able to take the kiddie seat (that attaches to
the down tube) and the tagalong at the same time but hte tagalong need
to hinge further back to avoid clashing with the kiddie seat.

Two thoughts off the top of my head:

1. Bob Jackson, makers of lovely bicycle frames

2. Take the existing one to a back street metal basher (try metal
fabricator in Yellow Pages) and describe what you want.

I suspect that lengthening the stub will excessively stress the clamp,
as well as putting the pivot too far back. I wonder if it would be
better to rearrange the child seat mounting and leave the tagalong as it
is.

Have thought about this and was planning or trying to make the pivot
sit above the back axle, or as close as.
Then rather than having the single clamp arrnagement on the seat post,
I was going to specifiy a triangle section - rather like a letter Y on
it's side - so as to distribute the weight on the seat post.

Maybe if you get hold of an old front fork you could attach that to the
rear dropouts or seat stays at the bottom, to the child seat at the top
and mount the tagalong clamp on the fork steerer.

Hmm. Trouble is I have rear disc brakes, so racks (e.g. burley piccolo)
won't work!

How about this:
Cut some forks short and mount them as far down the seat stays as will
clear the disc caliper - flatten the ends (cheap forks may just crush
down in a big vice, otherwise apply plenty of heat and a hammer) and
drill them to take U-bolts that are a snug fit on the stays. Wrap the
stays in a couple of layers of old innertube or similar, and maybe put a
strip of steel under the bolt to spread the load. Run a tube from the
fork crown to the seat-stay bridge to stop fore/aft movement. Use high-
tensile fastenings with nylocs.

Very Heath Robinson.
I Like it.

I saw a bike this summer where the baby seat was fitted to the rear
carrier and the bratdragger was fitted to a pivot at the back of the
same carrier - seemed to work just fine.

It will if the rack is rigid enough - the OP's kiddy seat is
cantilevered off the seat-tube rather than sitting on a rack (and he has
a rear disc brake that restricts the fitting of a rack) hence my
suggestion of a rigid bracket that would allow the pivot to be placed
behind the kiddy seat and firmly attached to the seat stays.

Love it! A much more precise description.
