Iain,

Techniglue is in the Carbatec catalogue.

I scrub the wax with white spirits (have used turps + metho previously) and wipe off with a paper towel - never had any problems. Haven't used wipe on poly, but no probs with oil or shellac.

Alex,

Thanks; I will try the wax on my next glue-up.

Thanks for the tips Alex and Rocker!

I'll try the wax / techniglue method on a couple of pieces of scrap tomorrow and see how it goes. Seems to make sense to me.

BTW, who sells white spirits? Bunnies? or do I need to visit a paint merchant?

Rocker - I always used wax when I used PVA glues a lot, and never had any problems with oil or various varnish type finishes afterwards. Turps, oil and the solvents used for most alkyd finishes are miscible with wax, so there shouldn't be any worry. I would be more careful to remove any wax traces if I were wanting to use the water-based finishes.
Cheers,

Looks like I woke up a rememberance of disorder and trial by error, Who would of thunk my little blog would rate 2 pages of experiences. :eek:

Nice (well not really nice) to see that I am not the only WWer suffering with Glue-Up Assembly Disorder (GAD)

Steve, I think that white spirit can be obtained at Rays Camping, Aussie Disposals etc under the guise of fuel for the coleman stoves (they have a name but having a senior moment ).

Isn't white spirit just another name for what Bunnies sell as mineral turpentine?

Nope, Rocker -
'White spirits' in our part of the world is basically petrol without the additives. Similar ability to dissolve non-polar solutes, but not oily & much higher evaporation rate than turps.
Coleman fuel is just WS by another moniker.
cheers

White spirits = Shellite.

Coleman fuel is the only stuff I can get here, and even the little bit of oil in it (for the stoves) gives no trouble.


Steve, you think the Dominatrix is accurate? I am currently tuning the M + T jig Mk. II and I am still debating wether to make the the mortises match the tennon, or make the tennon smaller or larger. Working at the 0.01mm scale here of course.

Just love that vacuum pop.

Schtoo,

I am inclined to agree that the Domino cannot quite match the accuracy of a precision morticing jig. With the Domino, I get a variance of up to about plus or minus 0.15 mm in the distance of the mortice from the reference face that the machine's plate rests on, whereas with my morticing jig the maximum variance is more like 0.03 mm. However, for most purposes the Domino is easily accurate enough.

With regard to the relative thickness of tenon and mortice, I think the tenon should ideally be about 0.03 mm thinner than the mortice. If you use a table-saw, a tenoning jig and a dado-set to cut tenons it is easy to cut tenons whose thickness is very precise. But the process is a lot slower than using the Domino, and you have to round the ends of the tenon to fit routed mortices.

Schtoo,

If I dry insert a Domino into a mortice cut by Herr Festool's wonder maching, I jolly near get a hernia pulling the blighter back out. Does it fit? You bet!

If making a line of mortices across a (flat) board, are they all absolutely the same distance from a) each other and b) from the face? WRT a) within 0.005" I'd guess (and assuming that I want them that way), and b) also, again, within 0.005". The catch is that it makes one be very sure that the boards are properly jointed

Uhh, yeah to all of the above.

The darn thing is better than what I am capable of, and better than what my level of ability is worth.

I'll put up some pics and details in the next few days, but I can tell you it will do MT joints from 80mm long x 30mm wide by 35mm deep and smaller (infinite), multiples, loose tennons, angled MT (both planes), dowels (as in make the dowel on the end of something) and prolly other things I can't think of right now.

Don't want to hijack this thread any more than I have right now.
