Blue gum slab table

[BrisBen]

First Post - be gentle

I have the opportunity to purchase some bluegum slab timber which I intend to make into a "heirloom" table.
I am told it was ringbarked in the 30's and is from "around the Maryborough area" (you all probably know how cagey these guys are about their sources).
I want to make a tabletop, probably doweled from two individual pieces, 2400 x 120mm. It will probably be thicknessed to between 40 and 45mm on a slab master depending on the slabs I pick.
The question is: what do I do then to finish it, remembering I have never attempted anything like this before, BUT I want it all to be MY work.
Criteria for finished table Durable enough for the boys to spill beer on for a card night, fancy enough for a formal setting when the inlaws come over, maybe one day the kids will do their arts and crafts on it and it will survive unscathed.

Any thoughts?

Do a bit of a search through this forum - there are quite a few threads which discuss different finishing options. I only joined up in Dec 04, and even since then have seen numerous threads on this topic. One great piece of advice I remember someone giving (wish I could remember who) was along the lines that of the 3 aspects of timber finishing: GOOD / CHEAP / EASY - you can never achieve all three with any one type of finish -

. If it's good and cheap - it won't be easy
. If it's good and easy - it won't be cheap
. If it's cheap and easy - it won't be good

This is probably an "over-simplification" - but not by much. I've been "full time" woodworking (after retiring from a previous career) for about 5 years now and mastering finishing was (for me anyway) the hardest aspect. All the other stuff (design, dressing, joinery, gluing etc) came with practice. But learning how to get a finish I was happy with took me years. And the learning curve is still steep.

There are more options than you can point a stick at. Oils, shellacs, urethanes, oil/urethane mixes, lacquers, etc - and they all have to be "mastered". You'll find threads on each of these if you research. And we all have our preferences -

After that long-winded intro - here's my suggestion.... After sanding back with an orbital to 180 grit, brush on a good coat of Feast Watson FloorSeal. (IF you can borrow a spray gun with pot - then spray it on - it'll be MUCH more even). Let dry (6-8 hours, depending on temperature etc). Sand sand back (orbital) with 320 grit. Then apply ( again, spray if you can) a second coat of Floorseal. This stuff is really durable (re your requirements) and will bring out the beauty of the timber. My advice - stear clear of the oils - they're dead easy to rag on - but then the problems start .. dull finish, water (beer) stains, etc.. At least that's my experience...

Good luck.

2 coats of Wattyl oil based Satin Polyurethane.

-Thin the first coat to around 50%-60% (as sealer)
-Sand the first coat (600 – 800)
-Thin the second coat to around 80% (PloyU is usually too thick to work with)
-Sand the second coat with finer sand paper (800 – 1200)
-Buff the table with polish compound

Forget about oil and wax. It will cause you pain and frustration in the future.

Brisben, 240mm (2 pieces 2400x 120) is bloody narrow for a dinner table, maybe you meant 1200mm width? I have a Jarrah slab table that is about 880mm wide and 35mm thick. I finished mine with polyurothane.

Heres mine, show me yours.
Made from Qld Kaurri and red gum.

Al :D

Whoops sorry Barry - missed a zero - yes it will be 2400 x 1200mm - hopefully an eight seater!

Ozwinner - mine is still sitting in the yard waiting to be thicknessed - I didn't want to get too carried away till I had all the info - maybe I should post a pic of the raw slab...

BrisBen, just to alert you that you're not getting "conflicting" advice - Wongo is spot on with his "oil based satin polyurethane" recommendation. Sounds like his Wattyl product is similar to the Feast Watson Floorseal (which is a Tung Oil based satin polyurethane). Wongo's sanding / application advice would do a better job if you're not spraying (i.e.- you're brushing on). If you were spraying - at least with Floorseal - you only need to go to a 320 grit on the sanding between coats. And don't need to thin. Although if you're spraying - thinning 10-20% with turps for the first (sealing) coat is OK.

(Wongo - do you thin with turps?)

Yes :)
