Will any glue stick bike plastics?

Oh no. Do that and the substrate will droop LONG before the rod's hot enough
to do its job.

That's how things generally pan out. Experience comes with practice, but
you've got to practice in the right manner or the (bad) experience just
keeps on happening.

The

You need as few obstacles as possible. That way you can keep the speed of
the gun/rod constant and also constant pressure on gun and rod.

Yeah. Works perfectly well.

I believe that's what it's called, but not being a builder, I'll take your
word

It doesn't need to be strong as it's only spreading the load out from the
joint. If the joint is a good one (not going to happen first time though)
it's not necessary, but a couple of layers will add strength accordingly,
although not exponentially.

As you say, that would be very manageable and give a very fine

I wouldn't use it on the OUTSIDE of the panel. On the outside, all that
should be required is possibly a light skim of bog (filler) and a couple of
coats of a decent primer. Flatting the primer should see any ripples
disappear. Start sticking glass cloth on the outside and the fairing'll look
like it's got a dose of mumps.

Ah, I've done similar with Perspex and I believe Airfix type model
cement does the same melt_the_two_surfaces thing?. The only 'issue' is
as yet I haven't found any markings re what plastic it is Beav?

I've dug that out ready ...

After applying a touch of silver 2 pack of course ;-)

All the best ..

Yeah, and I was really looking forward to spotting similar marking on
mine but none found so far .. :-(

Well, a decent weld might do! ;-)

Ok ....

Well, I'm not in a big bike circle as I've only ever been a 'biker'
for transport (and that was mostly on mopeds when I was 16 then a
Lambretta SX150 then my Schmitt for a couple of years when I was
working for BT). Now I normally only ride for pleasure and typically
with my family (We did go out on one ride out with the BM Club but
prefer doing our own thing). I generally ride with Daughter pillion on
my R100RT and the missus on her XV750, or hopefully soon with Daughter
on her Piaggio ST125 4/. The CB Two Fifty was supposed to be a
runabout but because of leaky rims I never really used it much. This
'tidy up' is just to make it a bit more respectable in general and to
brighten it up at the same time (it's currently dark blue and I hope
the Daughter may use it as her first real bike post test so would like
to improve the visibility of it a bit (FWIW) and the tank is showing
some external rust in places etc).

I'm sure I could soon learn the skill but I already know how to
fiberglass and *know* I'm not going to damage / distort the panel at
all. Also the bike shop suggested there are quite a pew people /
places doing a welding service now and often have painting facilities
to go with that.

All the best ..

Yep, don't leave home without it! ;-)

All the best ..

Swot I now know ..

Yup and don't get me wrong, I generally buy the tools and d-i-y
wherever possible (and partly why I can't get in the workshop atm) and
should a greater need arise (greater than a 3" long crack in a panel
currently working fine as-is with a drilled hole and a cable tie) than
I would get myself geared up to do the welding thing.

Indeed, and this panel isn't that occasion. It's maybe 4" wide, curved
and has two 90 deg lips on either end, not a nice open lower panel or
fairing off a sports bike or scooter.

BIL dropped a roll off for me today .. thanks for the heads up. ;-)

Ok .. In the past (when building boats or the fairing for my racing EV
/ 2 wheeler) I would thicken the lay up at the mounting / stress
points and generally feather them off into the panel (using
progressively smaller patches of CSM or woven roving etc).

Nope, I wouldn't, well unless it was a rat bike and then it would be
part of the character. ;-)

LOL .. Yup, and although this is 'only' the side panel to an old
CB250, it's a fairly long, straight, flat (in the longitudinal plane)
panel and would probably show that sort of thing up very easily (and
hence my reservations with the welding.) If one of the returns on the
edges went wrong a change of angle would be very obvious.

All the best ..

You're more than likely n the posession of an ABS fairing. Most are.

There ain't no such thing as silver 2 pack. Silver is a metallic paint and
that's a base coat (acrylic) over which one applies 2 pack clear lacquer.
You'll learn

Ok, thanks (so maybe why these basic welding kits come with ABS rods.
The better kits come with "a selection of 20 different types of
plastic rod ... " ;-)

<mutter, bloody pedants mumble> Don't need to Beav, I hand it to my
mate and go "ug" .. (point noted though) ;-)

All the best ..
