Fixing up an 'Adirondack' adjustable/folding outdoor chair. And have
it substantially apart at moment prior to reassembling. Seems to be
100% clear cedar.

Wooden pieces are all there and in pretty good condx. but some
improper fasteners (which look like modified plaster-board screws have
rusted away). Am wondering if it would be good idea to also use glue
where wood meets wood?

And if so what type of glue would be best for outdoor use on cedar?

For example there are 7 slats to the seat back which are each fastened
with two screws at each of three levels to the curved pieces that
support it.

Also two arm rests that were each held on by three screws, now rusted,
into end grain of vertical support pieces. Not good design! And may
modify them.

Also; as either part of the original manufacture or maybe added later
are two pieces of what at first sight looked like that perforated pipe
support/hanging strapping, used hidden, where the chair back slats
meet their supports! Maybe it wasn't pipe support metal but it has
also rusted (It's an outside chair after all!) and some rust has
stained some areas, fortunately sort of out of sight on the back and
some of the black can be sanded out.

Any other advice welcome; been thinking of building such a chair from
plans, when this one was presented with its few problems, as
mentioned, during community clean up week!

Thanks for any help. It's another of those 'too good to throw away'
projects! BTW I'm going to downgrade one of the two wooden picnic
tables on our large deck to the role of only cutting up wood on.

They both came free for the effort of being collected with our pickup
as owners upgraded to fancier 'store bought' (That means imported from
China!) tables and chair sets! (You can even buy them at the s.market
with your groceries now!).

A third one was also free and a few years ago I donated it to a
divorced mother with several children. Now remarried her husband has
put a new top on that one, doing a nicer job that I would. Anyway
reuse and recycling are alive and well. And boy does it help the bank
account!
