That's true about the setup. It always seems to take some trial and error. But once it's set right then you're away. The other thing is you need a different setting for every different thickness of wood.

Coco's astronomy tip of the day (No. 5)
At some point, if you show an interest in the night sky, it might be well worth acquiring a good book on the basics.
A fellow named Terence Dickinson has written a book called NightWatch...a very apt title for a book on the subject. If I had to suggest just one book, this would be it.
It guides a newcomer to the skies through simple and clear steps, as well as explaining what instruments you might want to use.
Tomorrow, we will chat about viewing both the sun and moon. Very special equipment is necessary for safely viewing the sun. We'll fill you in so you can enjoy the views of sunspots inexpensively.
Good luck if you are out comet hunting tonight! Hartley 2 is still near the double cluster.

Thanks Keith, I will be looking to buy that book, I can't get enough of all the new things out there. I am once again watching the Science channel about the solar system. One thing that puzzles me though, they have spoken of ice in outer space. Can ice be made or form when there is no oxygen, as water is part oxygen?

I believe there might be ice on some of the planets and moons which may not necessary be water ice.
I wish my chemistry was good enough to let you know which types of molecular structures could freeze. I think you can have methane ice, and I'm fairly sure there are others. But oxygen does exist in places other than earth.
We are able to measure all sorts of things in space by spectroscopy, and there are some very recent and extremely powerful telescopes with that ability up in space right now. Our scientists can often tell the composition of an object using spectroscopy. It's all a few layers above my level of understanding.
I'm quite happy to just be able to take a look at what's up there on clear nights!

I am with you there buddy, I attended a lecture by a Physicist several years ago and most of what he said just went right over my head. The things I did understand were just phenomenal.
That is really interesting to know oxygen does exist in other places than Earth. I hope you have a great night buddy.

I just got a second undercoat on the trims that the missus did earlier today.
She got the idea to stack this stuff on some stands we have here - but laid sideways. That way it gave her 3 surfaces to stack on. Good idea.

More assembly on the door this morning. First thing was to check the outer boards on the rails. One needed a short trim.
The saw is capable of easily taking off less than 1/16" very accurately.

I'm taking each step slowly with the door...and now the three center pieces of the rails are glued in place. Squaring up the middle one here. I feel it is necessary to do this to every one carefully so as to avoid any surprises in the final assembly.

The glue I'm using sets up sufficiently within one hour so that further work may be done. Here I'm gluing the lower board on the bottom rail. But I don't have clamps which reach 12" or more.
So the solution is to clamp a good hefty piece of wood above the clamping area in question, and then use a series of wedges to exert the required force on to your boards.
First up, I used a 4 x 4 to give lots of strength and clamped it to the bottom of the door.

I don't think these are expensive Shu...about $30 and around $15 for the replacement blades.

Following the install of the 4 x 4, I added shingle shims in pairs underneath to provide clamping pressure. In one hour I'll move that setup to the middle rail and do it all over again.
A dead blow hammer sets the shims perfectly.

I think you need a rock clamp there  . dd...
