G'day Pete. Welcome.
I was going to buy an Ozzie Jig at the Hobart WW Show but the guy selling them seemed so bored and disinterested when I asked him a question that I just walked away. His wife(?) was in the background repeatedly counting their take for the day and was equally uncommunicative.
They did seem to be a good jig but I guess I'll never know for sure.

Not sure what you mean by the T format. Can you be more specific about what exactly is out of square with what?

I've had no problems with mine, except for the time I dropped it on the concrete floor and bent the end fence. Couple of blows with a hammer against the jig blocks put it back to square. I always get perfect alignment, and am still very happy with the OMJ.

Hi Zenwood, by'T', I mean with the fence between the 2 blocks.Set yours up, place a straight edge across the 2 blocks & tell me it's flat, also place a square on the block against the fence & tell me it's 90 degrees.I can see daylight doing both tests. Am I just being precious?

Pete,

Don't know if you're being precious, but here's mine for comparison. I'm perfectly happy with its performance.

Flatness test

Putting a straight edge across near the middle (pic 1) there is a slight ridge caused by the top of the central fence that makes the straight edge rock a bit (this would have no effect on the jig's performance). Putting the straight edge at the ends -- beyond the end of the middle section -- (pic 2, only took a photo of one end, but the other was the same), the surfaces are dead flat.

Squareness test

The left hand side (pic 3) is dead on. The right hand side (pic 4) shows a teeny bit of daylight at the doesn't worry me.

If your results are significantly worse that mine, and mean that you can't use your jig, I'd send your pics to Des Fenelon and ask his advice. I found him quite helpful at the last show after I dropped my jig, and he showed me how to bash it back into shape with a hammer. Helpful, but chose your timing carefully: during a lull in the demonstrations. I don't think he likes being interrupted while 'in the zone'.

Emerald I ran a square over mine as well and a fraction of light, the right angle was damm good though
Don't know accurate you need to be mine I would guess is within 1-2 thou
and for me thats more than enough

Checked that gap on the right, and could just fit a 0.05mm feeler guage in there (2 thou.)

I've had mine for years and never had a problem. That's mainly the reason I've never felt the need to buy a biscuit joiner.
Cheers,
