triangle flag shadow boxes

Create a Post
A flag when folded properly has one 90º and 2 45º angles, so your miters would have to be 45º between the short 17" sides and 22.5º between the short sides and the long 24" side. Piece of cake...
 
Jo,

I have cut shadowbox moulding on my Phaedra setup but it isn't as easy as it sounds. Your saws need to be right on the money to get the tapers exactly the same. As the angle decreases, the length of the miter lengthens a bunch and, if your saws aren't exactly set to 22.5&#186, the tapered ends will turn out different lengths. So much that they will show.

majohns,

There are a number of companies that sell premade flag cases and they are reasonable. YOu might want to check out the line of flag cases that SpartaCraft carries. Their phone # is 800-282-8044.

I wouldn't mess with trying to build from scratch when you can buy them already built for less than what it takes to build them from scratch. Now, if the customer has their heart set on a particular moulding, then you may have to bite the bullet and build it to suit.

Jo, Thanks for your reply!! yes I have checked out site on the web and found great Flag boxes. and I did relize after alot of trouble , the 45 and 22.5 cuts. The custumer dose want this particular moulding/ I do believe I cand do it but its not gonna be a piece of cake. what I'll have to do is to is make a 90 degree fence off of the saw fence to get the true 22.5 cuts, I've did a little practicing with scrap to see how it would work. and it dose but not fun to do.
 
Dancinbaer, Glad for your info, But it won't help unless your gonna make a box from scratch. I gonna be using reguar shadowbox moulding .and by the way I found that site today myself and it seeems to be the only site that even come close to giving instruction on that subject. Thanks anyway.
 
Well, I had to ask, because I have done one, only one, and never another one!
Other multi angle frames are truly a piece of cake, but not that one, it is very difficult. I much prefer the Sparta Craft line (and their quality has gone way down).

Good luck, rmajohns! Give us a report, ok?
 
majohns,

Thanks for the compliment but I feel sure that Jo is alot better looking than I am!

Regarding your problem, what kind of saw are you using? I am assuming that you are using a bench saw as I can't see how you can cut the proper lengths on a regular chop saw using an auxillary fence.

It can be done on a regular table saw if you are very precise in marking the length of your frame legs and watch the positioning of the moulding on your fence when you cut. Don't allow the moulding to go into the throat of your saw too far or you will throw your length off. I am just making educated guesses as I don't know what kind of saw you are using.

Keep us posted if you run into trouble. I have had my share of problem cuts and have figured out some real off-the-wall solutions to getting the job done.

An after-thought on cutting this on a table saw. If you use your miter fence and attach a longer piece of hardwood that you know is straight and square to it, (there should be 2 holes in the head of the fence that will accept screws), it will help to hold the moulding steady during the cut. Then you could set the fence to 22.5&#186 and run the moulding through the saw. My fence extension on my Delta saw are made of oak and finished so as not to warp and extend to within 1/2" of the saw blade.

Sorry Frameguy! I have a table saw in my freezing cold garage, as a last resort. but I'm using my dewalt miter. and mounting a hard piece of wood straigt out from the saw fence 90 degree. I know its danergous, But I seem to live on the edge anyways LOL!
 
Well, majohns, you have to post 21 times to pass the initiation for new Grumblers.

(Or you could send me a crisp new $20 bill and I'll see if I can put in a good word for you to Framer.) ;)

P.S. How'd a truck driver get interested in framing anyway??

Who said anything about cutting it? rmajohns just wanted to know the angles! :D
Actually I've cut these on a chopper by making a 90º jig to clamp against the fence and a piece of wood to support the rabbet. I've also cut them on a double miter saw by making a 22.5º jig clamped against the fence. Watch your fingers though!!!
In fact, rmajohns, you might consider making a 22.5º jig instead of a 90º jig. You can leave your saw set at 45º that way. For a one shot deal you could probably make the jig out of a couple of layers of foam core. Should be fairly easy to mark out and cut the jig accurately that way. Stick it down with ATG. It would help if you can clamp the moulding down while cutting. If you have one of those fancy miter sanders the 22.5º jig would work on it too.
I'll bet when you took this job in you couldn't imagine what a PITA it would become. Live and learn. I hope you charged a ton of money for this, but I bet you didn't!

For those masochistic types that enjoy doing this kind of thing, the Barton Multi-Angle Guide is a valuable resource for determining cutting angles and lengths.

They do have instructions for flag cases, but they don't seem to work out to those dimensions.
 
Shouldn't this topic be moved to Warped? :rolleyes: Trying to cut this frame will definitely warp one.

I'm afraid I, as well as others, am guilty with having some cruel fun with your topic rmajohns! ;) , but you seem to be taking it well. Apparently many of us have struggled with flag frame angles, and have less than wonderful memories about it.
 
It seems to me that a frame with a 24 inch base and the angles Frank mentioned will have to be 12 inches high - not 17. If it has to be 17 inches high, the angles will change.

In other words, for angles of 45 degrees and 22.5 degrees, the height of the triangle will have to be half of the width of the base. That's why the Barton guide won't give instructions for a flag case that's 24 inches wide and 17 inches high.
 
21 Times is that all!! I've only been going to this site since 2001 and my member # is 1540, A low # conpared to lot I've seen Hmmmmmmmmmmm. You guys are great!! I'm a local Truck Driver, I haul the mail from Nashville to Atlanta 4 days. Anyways after 20 yrs of that < I decided to change profession and I love doing great thing with my Hands and Framing is Fun,and very gratifying.
 
rmajohns,
I bet that was, or could have been a pretty drive!!

Excuse Ron. He likes to show off his geometry and trig skills.
 
Yes Charles its a awsome drive thru the hills and the valleys and especially monteagle Tn, I still do it because my frame shop is quite off the ground yet. right now the shop only pays it own way. Its only about 7 Months old and I'm paying my dues, If you know what I mean. I do believe I will succeed. Untill then I'll dive my head off. YECK!!! Frank I gonna take your advice about cutting that angle jig, I think it will do the job. Thanks!!

Ohoh, I'm quoting myself.
I just wanted to show Ron I was ahead of him on the trig...17"sides and 24" sides.
And your right , it would be 12" tall unless you set it down on a short side then it would be 17" tall. OK, so sometimes I'm a smarta$$.
