I need DB's Southern Sorghum. I am skinning foam wings. There are other method's, this works best for me. I will PayPal you, if any available. Please reply if you have viable product.

Thanks,

Thanks. I got the last two bottles. They have stopped carrying it.

crank, yes there are other ways to skin wings and i'm sure you don't want to hear of every way there is. however gorilla glue or it's competitors is an easy and insanely strong way to accomplish wing skinning.

Grrrr-illa Glue. That's some stuff. I have two 7 oz. bottles coming, and have posted on the tips and tech forum, no luck yet. I forget how much I used to use on a wing and stab. I may be OK. I will ask them where they buy it, I am sure they don' mix it up at their location. There must not be a heavy demand for it, with the ARF market as it is today. This is for P-6 # 2. Maybe from here on, just get someone to do the skinning, I can do the rest.

Crank

You can find water based contact cements at home improvement stores (Lowe's, Home Depot, etc) that will work just like sorguhm. If truth were known, it's probably the same stuff.

Oh no!!

Crank,

don't do that... one of the biggest kicks I get out of building foam core wings is the point when you end up with your two prepped cores, skinned, trimmed and sanded to identical shape in the stack. All your hard work is concealed under the skins so seeing them turn into smooth and lean wings is just a fair reward...

When I'm done, I almost want to go get a knife and fork and eat the darn things. I find them as enticing as a good steak! I have also had other visions resulting but I won't get into those...

David.

Burtona - Thanks for your input. I have had a few message's like your's. I will check it out this weekend. Maybe I can ask DB where he get's that stuff, start bottling it, if there is a market.

Crank

Igot the last 3 gallons Dave had left.. I am waiting on bottles now. I talked to Dave, Iwill be carrying it in the future... Watch the website for details..

I use water-based contact cement for skinning foam wings. So far I have had excellent results. I used to use epoxy, but I hate the mess.


Ed Cregger

when i saw how far polyurethane glue expanded into my foam wing cores i was hooked. the amount of glue it takes to sheet wings is so little all it has to be is a glossy shine on the cores and that's it. the glue will expand 1/4" into the foam if the wing assemblies are clamped thoroughly. vacuum bagging would have similar results i suppose.

I'm going to have to try that stuff (polyurethane glue). Do you have to "hop to it" when using it (work fast)? I'm not good at that these days. I forget what I'm doing and wander off to the kitchen or get lost in TV. <G>

I'm smiling, but it's true.


Ed Cregger

not really Ed. just make sure you have everything ready to go. especially the clamping system. i used 3/4" mdf and lots of clamps but i might go to a vacuum bag system on my next wing. more later, company just arrived.

Just a quick question - does the Sorghum have a shelf life? How long would a sealed bottle be good for? Anybody know? TIA!

FB

Freebird - I was trying to think of that, as I have had many bottles of it, years ago, and it did have a shelf life, but a very long one. I guess you could refrigerate it. I got the last two bottles that DB had. He shipped the last three gallons he had, (pre-bottled), to Don Turnock at Wing. I put my order in for 5 or 6 bottles. They will be in 8 oz. bottles, I think. DB's was in 7 oz.

DB is not going to handle it anymore. Before Sorghum came along, and DB got it when he bought Southern RC Products, which had the retracts, etc., we tried 3M contact cement and a rubberized contact cement, that was yellow. Not good. I am sure the epoxy method works, but could be messy.

Note: I could not get there this weekend, but Ron Chidgey and wife were at the Andersonville, GA SPA contest this past weekend, and they said he flew like the old days, had an Atlas there that was outstanding. This was Ron's first contest in many a year. I guess you guy's know, from Tiger Tail fame. Here he is from the old days.

Hey Crank:
I saw some bottles of the stuff at Hodges Hobbies.
You might give them a call.

Hey - Thanks, better call, should have sent me a PM, secret's out[sm=72_72.gif]

Talk to you later, bigger planes stuff.

I have a bottle or Sorghum on my shelf which I keep as a souvenir. I bought it about 25 years ago and just never used it. It is now for all intensive purposes unusable. But... some feel that the epoxy method is messy. I've never found so. A little wax paper takes care of any epoxy drifiting off the sheeting and once spread with a spatula and excess removed (about 1/2 typically), there's really nothing to drip - the sheeting just remains wet but essentially free of glue flow.

I've yet to have a drop of epoxy fall on my "coring" table.

I admit I am curious about the GG approach though and wondering whether clamping is required. What I like about the weight approach is that it is easier to distribute the load evenly - somewhat akin to bagging.

David.

HobbyPoxy used to make the large tubes of epoxy, called Number 2. Took about two hours to set up, slow cure. What are you guy's using for epoxy on this ?

Crank

Now that you mention it, I think I have some Hobbypoxy Formula II hiding in my workshop somewhere. My father used to use it a lot for firewalls, fuel proofing, etc. I don't remember if he used it for sheeting cores though.

Received 6" X 48" X 1/16" skin's today. I asked for matched pieces, all look great, excellent quality. Balsa USA.

Having covered many foam wings over the years and hated the mess, I have finally got onto the answer.

Bill Evans of Simitar Models from Bishop.Cal. uses a doubl -sided adhesive tape. It is 2" wide and comes in a roll enough to cover two .60 size wings. The tape is so simple to apply and once the whole wing is covered,you remove the backing paper and what is left is a very thin and extremely light layer of adhesive. It sticks like the preverbial and does not give you any chance of errors in lineing up the skins. It is definately the lightest and easiest I have ever used.

The tape that Bill Evans originally used was made in USA. but the tape being used now is of Japanese origin.

I believe Bill is not in the best of health and the tape may no longer be available from him but it is available here in Australia.
