After reading indplswoodworking’s post on the simple mitre Box produced as a result of calibrating their saw, this prompted me to post this “Test Cube”.

How it came about was a result of seeing a box LLWW had produced with a mitered base.
I wanted to see if I could reproduce something as precise as Larry’s on my compound miter saw.

As it was purely another one of my ‘experiments” I only used some MDF I had lying around.

I set up the saw to cut precisly the width of the material into 45 Deg angled squares.
Cut six squares out.
Glued them together as pairs.
Assembled them into a cube.
Checked the results and lo and behold they were very accurate.
So I set to and made a second one just to make sure I didn’t “fluke it”
Sure enough I obtained the exactly the same results.
So I set them on the bench and took the accompaning photos to share.

Conclusion:-

Yes you can get the accuracy and repeatability with precise set up and skillfull cutting using a miter saw.

So what am I going to do with them? Who knows, possibly glue them together and veneer the outsides.

Enjoy

You know, that might be a great little puzzle box…hook them on the easy one’s and then really make them work on a much harder puzzle.

I have made cubes like this as well but mine have been done on the table saw. Set the blade to 45 degrees, set the fence and make all the cuts. Theoretically is should be perfect every time.

That’s an interesting exercise. I’ll definitely have to try it the next time I’m on the miter saw. It kind of reminds me puzzle games I’ve seen. As a matter of fact, by gluing 3 sides together, It should make one of those puzzles boxes that are hard to figure out how to open.

Those are not the best looking 45 degree joints I have seen. I think that you need to tweek your settings.

Rob, can you post closeups of the miter joints? From a distance they don’t look like they come together. Thanks,

OMG there is in fact an error!

It looks like the saw may not be set up correctly

I now also have the issue that the clamps I used to do the glue up of the two pieces needs to be considered in the investigation

I will contact Einhell straight away for an answer.

Trying to find a precise accurate flat work area is a problem, so I hope the cast iron on my Table Saw is not defective.

Any way just as a distraction I looked up at my wood stash while I was trying to photograph the Test Cube and saw a tail poking out, wondering what it was I gave it a tug, and a small head appeared around the side as if to say “Do you mind”

Did you ring?

It was just my friendly Water Dragon having a snooze on some of my Purple heart stock.

Enjoy

Rob, forget the miter for a minute. Look at your top pic and the pencil line. Your saw does not cut at 90 or the square you used to draw the line is not square. You may have more than one problem.

OK, looks like a 90 deg error as you suspected, I managed to get the part with the pencil line on it and my square. There is a problem!
Aurora, (the wife) is home and has the car in the garage now so I cannot get all my gear out just yet.
Need to wait 12 hr and I will post some more photos whenIi can get access to the gear again.
Standby!

Morning all.
The saw saga has now been added as a review on tuning the RT-XM305U.
In closing there were as reported both 90 and 45 deg precision errors that needing fixing.
Keep tuned for my next “Test Cube” ...oh no not more cubes again !!

P.S. The Water dragon stays, he/she and their family have been around for about 5 years, ever since I started feeding them fish from my pond at $25 a hit and kept wondering were all the fish were going!!

Cool. I have blue tailed skinks all around my yard. It’s spooky to hear the leaves rattle around out of the dead, calm, silence as you walk by and not see anything.
