Completing a table

[smidsy]

Hei Guys,
In the finishing stages of a two teir pine table.
The construction is biscuit joined pine to make panels about 500mm x 500mm with jarrah cross beams underneath and the 4 legs attached by dowels to the jarrah.
For the finish I am using Monocel ultra gloss varnish.
I am at the point where all the components are done, I just need to assemble, varnish & sand.
Considering that this is a coffee table that will get hard use, is it worth me sanding finer than 400 grit - if so, where in Perth (south of the river) can I get better than 400 grit pads for a Bosch ROS sander.
In what order should I do the sand, varnish & final assembly?
I have a compressor and cheap spray gun but no where set up for spaying, so if I spray it's gonna be on a tarp in the shed - is it worth the hassle or should I just use a roller.
Cheers
Smidsy

You can buy up to 1200 grit wet and dry paper almost everywhere. I cut it down to suit a Bosh sander.

This sander is one of the random orbital sanders so I need the round velcro backed pads

Buy a $2 cork sanding block.

I never use my ROS above 400gt on fine work as you can getter get a better feel hand sanding as the finish gets finer.

Abrasive wholesalers that have a retail outlet as well usually have them, but may want you to buy in quantity.

I've had brilliant success at panel beaters they generaly stock 150mm velcro disks at 600 800 1200 and 1500. Most it has cost me was a 6 pack.

NOTE If you are useing it for wet and dry oil burnishing it doesn't matter what hole pattern you get, in fact no holes is better, you don't want the dust to exhaust, you want it to form a paste with the oil and fill the grain. You definetly don't want it in your ROS. When I have the correct hole pattern I offset it to ensure no paste goes in to my sander. (this isn't much good for the backing pad)
