Further to today's conversation.

Minimum tools needed are going to be:

flat blade screw driver
14 mm ring spanner
5 mm Allen key
Chain breaker (one that can re pin as well)
socket (can't remember size) and torque wrench
22 and 24mm spanners to remove rear wheel
10mm spanners to adjust axle

Consumable list:
front sprocket
rear sprocket
chain and joiner link
2 man job, therefore at least one cold beer for mate.

If your that short of cash, I can lend you a new 14 tooth sprocket until you can pay for it or you can have my old 15 tooth unit that's still good but you'll have to get on a train to Granville tomorrow to collect. At least that way you'll only have to find the cash for a chain and rear sprocket and pay for install (at most $200).

BUT
By the sounds of it 32,000 km and deeply hooked sprockets and a chain stretched to ******y&back you really must replace the lot. On ebay you can buy a set for around $150 I suggest you do. Tools are going to be another issue all together and if I wasn't off to family court on Monday to try to get my girls for Christmas time I'd bring everything and lend a hand, I really would. Unfortunately your going to have to push it there.

Just remember: That what doesn't kill us makes us stronger.

Only 2km, take water think positive.

Now the controversial comment.

Since the chain is no good, I'd be tempted to take out a pair of links, and that should get it back to adjustable length (one pair is 32mm) surprise surprise axle adjustment is 35mm. It will only cost about $50 - $80 to buy a chain breaker but get a good one (that re pins as well). Restrict your riding to bare minimum and easy on the go fast, your sprockets will eventually let the chain ride over the teeth and you definitely don't want that. You might get another month or two. It would be better not too.

But we've all be broke and I guess your going to have to sort it out somehow.
