boomerang tips for adding positive dihedral MUST SEE

[JoeFromDayton]

I may have ended up with too much positive angle of attack on that arm but it has dihedral now! Only throwing it will tell. That's for another day.

[supergooddeal]

@JoeFromDayton Give it a day and it will almost go back to it's original shape but not quite. You always need to go that little extra in the bending process to accomplish the final result. Best

[JoeFromDayton]

Great tip here, Vic. I was dreading having a sit down session with my boom to get the anhedral out of the lifting arm. Instead, I threw a clamp above the warp and propped it up with some boom blanks! I'll take it out later and check it in the morning.

[supergooddeal]

@JoeFromDayton Hahahaha, very cool idea man. Have you seen my ITALIAN CURVE video? I built a device to do what you just explained. Check it out if you get a minute. Let me know how your experiment worked.

[supergooddeal]

@JoeFromDayton The vid I spoke of is in the video response to this video ;)

[GREE7107]

Great tip! Just tried this on two boomerangs I'm making as Christmas gifts and it worked a treat! As to whether they will actually fly... well that's a different story!! Thanks for posting so many interesting videos.

[supergooddeal]

@GREE7107 Your very welcome. I've been making them long enough now that I don't need to do this anymore. I am more picky with how the wood lays before I even cut it out. I look for a neutral or positive dihedral in the ply then trace my design out on there. This way the wings will already have a natural lift without needing to do this heating method. There are also a number of undercuts to achieve the same thing. Soon I'll be posting a series of (how to build a boomerang) Peace

[GREE7107]

@supergooddeal Great - I'll look out for the new series soon. I've only just started building boomerangs - with mixed success to date! Hoping the dihedral will help - currently waiting for some decent weather so I can test them!

[anasalwash]

thanks for these tips man , but dont you think that if you spray it with little water before the microwave of air drier can bend the boom easier??

I know wood and water are not friends , but just a thin spay

[supergooddeal]

@anasalwash Very good advice if it is a personal boom. If I am selling it I wouldn't. I have not had to actually do this in a really long time. I try and make sure my ply is either really flat before I cut the boom out or at least warped up. I actually changed the design of the boomerang in this video also. By making the arms sweep back more instead of forward makes the boom naturally fly higher with no bending. Thanks for the comment.

[MrPokemonfan431]

@supergooddeal does it fly?

[supergooddeal]

@MrPokemonfan431 You can see me throw it in my video called Whizzer boomerang.

[killedgrave]

thanks for the hairdryer tip because i dont havve a microwave:P

[mieggiel2]

Where did you get the plywood? i cant find any good plywood...

[soyaoyeng]

is that how you use your microwave?

[supergooddeal]

@soyaoyeng Yes, If you add a little salt the boomerang won't taste so bad LOL. Actually I do not have a need to heat them anymore. I finally master the art of carving the airfoils to do the job better. Also the wood you start out with must be as flat as possible.

[jeepluvr81]

also, I shaved a little off the bottom leading edge and it does come back rather well now. Although, it still requires a decent toss, which is ok for adults. I am making a couple for 2 kids, and I wanted something they could throw a little easier. Maybe I'll have to stick with the lighter 3 ply for them. It barely needed any strength to toss it and it came right back every time.

[jeepluvr81]

Well, the tri-blade is 12 1/2 in from wing tip to wing tip. Or when vertical, sitting on a table, 11 1/4 from the table to the tip. It weighs 2.5 ounces, and I used a 6mm baltic. It's the only thing I can get my hands on around here (so far).

[jeepluvr81]

Ok, I understand what u are saying. Now I'm making a tri-blade. I made a prototype out of cheap 3 ply. I added the dihedral. Came back perfectly. So I made it out of some heavier baltic, and I tried it without bending the wings. It pretty much lays flat on the table. I threw it, and it will come back around, but nowhere as good as the lighter wood. And I have to really toss it hard. Some plans I see require a cut/angle on the bottom. Some don't. Would a hole in the center help? sorry for the ?s

[supergooddeal]

My idea behind a heavier boom is this. Smaller booms require thinner material. This makes it lighter. Big booms require thicker wood making them heavier. Much determines what you want the boom to do in flight such as big circle or small circle. Also thicker booms usually require a harder throw. A hole in the center makes them fly further out and drop quicker at the end of flight. I would make the heavier baltic a bigger boom. How big in diameter is it now? weight? and how thick is the baltic?

[jeepluvr81]

Ahhh... how did u change the angle? Do you mean sanding an angle on the bottom of the leading edge? or another way? I've always just put sanded the bottom before. And for the record, I glued it back together just to see how it flew, and it actually worked perfectly. A catch every single time. :) And that was just a 3 ply prototype... I just made 3 more with some baltic birch.

[supergooddeal]

I actually mean changing the design of the boomerang when I refer to changing the angle. How much the arm sweeps forward or backwards determines how high or low it will fly. I hardly ever remove any wood around the top tip or undercut. When I am finished the boom lays flat on the table. Now lifting or dropping anywhere. Then again you need a really flat piece of wood to start with. Feel free to ask again if you don't understand me. I easily confuse people.

[supergooddeal]

Check out my video on "Showing how I build a boomerang" The airfoil on the boom in that video is how I do all my booms now. I don't even make the trailing edge go all the way to the elbow anymore. Only take off as much wood as needed.

[jeepluvr81]

I'm just now making my first tri-blade... this video is probably one of the best on youtube for showing how to easily make a dihedral bend in thr boom. Thanks alot for your instruction. Although, my first attempt I broke my boom. Oops. Too much.

[supergooddeal]

Thanks, Yeah I have cracked a couple myself. I actually don't need to add dihedral anymore. Just changing the angle of the wing made it climb. Things you learn as you go along.

[mirsasau]

imy cus got hit in the face but when we ran for it he pushed me off

[pcsbyte]

Good Stuff

[jmmcnc]

i have a question...an undercut doesn't do the same thing as what you are doing?

[supergooddeal]

Undercutting and bending the tip up is the same basic idea. If I have a boom that is flying to low, I will start by removing wood from the bottom side of the tip of either the throw arm or the trailing arm. This will usually do it unless it is a wacky design like the "Tossbow". That one I need to do both. Now if you choose the removal of wood make sure to not take away more than half the thickness of the wood. Do the opposite if your boom flies to high.

[jmmcnc]

ok...thank you

[jmmcnc]

how thick is that boomerang?

[supergooddeal]

All my booms are 10 ply 5mm thick. I just added another video with a hand held tool I invented to also add positive and negative dihedral. Works Awesome. Check it out when you get a minute. Peace.

[jmmcnc]

thanks man...i was doing it with water vapor but this is so much easy

[supergooddeal]

No prob. I find that I use the hair dryer more now than the microwave. Takes a little longer but is more permanent. Hey you should post some throwing videos.

[jmmcnc]

next week i will post some videos in my page

[nate8910]

little bit but most of the time it doesn't come back

[nate8910]

THX SO MUCH!!!

[supergooddeal]

No problem. Do you throw bro?

[Artinct]

Thanks Vic, Nice video.

Art in CT

[dcinnovator]

Dude! You smaaaaaaaaaaht!

[supergooddeal]

thanks man! Do you throw?

[dcinnovator]

I will next time I stop in!

[supergooddeal]

Hey dude I thought the name looked familiar. When I clicked on the name there was nothing there. So when are we going to disk golf and rang. I think I grew 4 gray hairs since I see you last.

[dcinnovator]

Sheet mang! Hyou ain't keeding!I was thinking of heading up this weekend, but I decided to get drunk instead- but I gotta get up there sometime soon, hopefully in the next couple weeks, or else you're going to have to paint the rangs day-glow so we can find them in the snow!

[supergooddeal]

No problamo, I'll be packin the snow down on the lawn with the snowmobile. The only thing getting lost will be the throwers. Miss ya bro-lots to catch up on.

[bvdrangs]

Interesting method but seems like too much work. I don't add diheadral unless the boomerang doesn't work in the first place. When I do need to do it I just microwave the rang for 20-30 seconds and add the dihedral by hand. It is a pretty fast process.

[supergooddeal]

20-30 seconds in my micro would melt the glue to much. Different powers vary. This method is pretty much for someone that is putting out several rangs a day. I also would not add dihedral unless it needed it. I'll try to be more specific in the next videos. Thanks for the comment.

[flyingscience]

I'll show this on a rang forum , you may get more feed back .We all like to see the varieties of methods .-Greg

[flyingscience]

Other methods use clamps and a wooden dowel as support .Same idea slight variation .Bowl tuning will use a big bowl and clamps their are photos of this on net.Google bowl tuning boomerangs .

[supergooddeal]

I'd love to see these methods being used. In the near future I would like to make a table built special for any style rand for adding positive and negative dihedral and even angle of attack. Time will tell.

[flyingscience]

5 The puritan rang makers dont like the microwave method .They claim it weakens the wood slightly and will be more prone to breaking in the future.However experianced throwers dont make bad throws often .

[supergooddeal]

I've heard that also. I'm not so sure that it is the wood that is weakening. I think it is the many layers of glue. Certain types of glue cannot withstand being heated to many times or for to long of a time. It changes its properties. I would suggest only heating it once in the micro for shortest time needed. I sill use your method if I don't get enough dihedral the first time.

[flyingscience]

4.Sometimes the 3rd wing will have cooled off too much and you will need to heat 1 tip and warp again.Dont reat the other 2 tips youll loose the warp .Heat last tip by air or fire method- not microwave.

[flyingscience]

3 . Usually I will microwave for 22 or more seconds .I will then bend each tip by hand on counter top and hold for 40 seconds .That is all the time it takes and it won't droop much when it cools .

[flyingscience]

2. My impression is that you haven't microwaved it long enough and you have to make up for that by letting it stand so long .

[supergooddeal]

Ya you may not have to let it stand as long as I said. Probably only long enough for the wood to cool which is only a few minutes. I just started using this method a few days ago so it still needs a little tweaking.

[flyingscience]

1 . Supergooddeal thanks for posting , their are many ways to go about warping these .If it works and you get good results that's all that matters .

[VENGEVENGE]

nice technique

will try

peace

[supergooddeal]

Well that should be easy. Just check out my other videos on boomerangs and you should find 5 different types. If your new to the sport I would suggest my Whizzer. Let me know if you can't seem to find them.

[deepboss47]

where can i buy a boomerang cus im too lazy to make one -_-

[dcinnovator]

Just ask supergooddeal, he'll make ya a supergooddeal :)
