Here is the finished product almost. It just needs one more coat of estapol and I haven't put the extension bits back in as I can't do it on my own without scratching it.
It was $109 for the table inc delivery
$70 for sander, which will be used again
$60 for supplies (stain, varnish etc)
So a very cheap table, but now on the lookout for secondhand chairs that I like, which I can do up to match the table stain. It's not perfect, but I am very happy with it. The colour I used is Wattyl Wood Gel Wenge.
