Built some scratchbuilt cannon barrels for the Skyraider

QUOTE: Originally posted by maddafinga The cannons however, are two part affairs, a thicker base, then a barrel that sticks out from that. I don't remember offhand what measurement the cannons were, but it can't be a whole lot larger than the mgs.

Find out what caliber they are and then find the tubing that is closest to that size inside when converted to 1/72 scale. Then find some brass tubing that is slightly bigger diameter then the hypodermic is on the outside and you can slide the hypo tubing into the brass tubing as I did, glue it with CA and you are all set.

Just tell your doc that the next time they jab you that you want to keep the needle. With a little luck, after they finish laughing and you explain why, they will feel sorry for you and give you a clean one.

According to smallparts web site the 32 and 33 gauge hypodermic tubing has an inside diameter of .004" The 32 gauge is .009" on the outside and the 33 gauge is .008" so either would probably work. You could even go bigger if you are not trying to be exactly correct to scale. Mike

Well, the mgs are in the wings and the barrels are flush, so I'm not worried about them. The cannons however, are two part affairs, a thicker base, then a barrel that sticks out from that. I don't remember offhand what measurement the cannons were, but it can't be a whole lot larger than the mgs. Either way, thanks for posting that site!

Glad you guys liked that site, Styrene (Gip) told me about it a while back and I bookmarked it too.
The only negative thing is that they only ship 2nd day air on orders under 10 lbs and it costs $10.95. Get a few people together and buy a bunch and that will make the shipping cost seem like nothing.

Great link Mike, simply great. You've saved me lots and lots of hassle. I've bookmarked this site for keeps. Any idea what gauge I should look for to be the cannon ends on a 72nd scale Spit?

Thanks Mike! You da man!!!!
I went to their site but, couldn't find hypodermic tubing. I was about to post and ask where to find it. THEN! (slapping forehead and doing my best Homer Simpson) DOH!!!
Do a search, Stupid!!!
Thanks again.

Madda, I'm not writing a detective novel but that could be a great idea.

Mike, you're a wise man. Small Parts even send to third world countries like France so I asked for a catalogue.

But keep a spare needle complete ( you can cut the pinching side ) for my idea ( the thinner the better).

Why not just buy some hypodermic tubing from SmallParts.com instead of going through all the hassle? http://www.smallparts.com/

I am a dental tech, but not a dental assistant. We only deal with the patients to match the shade of their teeth, and not with needles at all.

What I do have at work however is a great great motorized handpiece with a quick chuck and tons of bits, stones, discs and wheels. I even have an air powered handpiece with high speed friction grip burrs. I haven't had to mess with a dremel at home because of this. I also have lots of old hemostats that I take home as they loose their usefullness at work, so I never have to worry about tweezers.

Sadly though, no needles. I have been thinking about taking my Spit to the drugstore and show them what I need and what I need it for. That might work I think.

Madda? Aren't you a dental tech? Can't you get needfles that way? Or am I confusing the vocation with something else?
Just a few questions.

Are you writing a detective novel Jose?

Thanks Dave, I'll remember that.

Everyone else,
As for needles- Pharmacies sell syringes for certain allergy medications these days.(in case you don't have an insulin card) Maybe you could talk with your M.D. I don't know.

Many larger cities these days have needle exchanges, thank goodness, where the addict can exchange old needles for new ones. Some of them provide people with cards allowing them to possess syringes. So he/she doesn't throw them in the gutter while running from police. Therefore, small children, or adults for that matter, don't get their hands or feet on them. (fact- 99% of intravenous drug users have contracted Hepatitis C nowadays, no thanks to the war on drugs!) Yes, it is a lower class misdemeanor.(Class-C, I think) Punishment varies from state to state.

One can also go to a feed & supply store. If there happens to be one around, they sell vaccines already prepared for dogs, cats and horses, etc. Maybe you could give your pet his annual shots.

Madda, I wish you good luck for your quest. By the way, note there are a number of different diameters for different uses so you can slip one needle inside another to simulate a number of different things ( barrels, pistons...). Another idea : what if you proved the drugstore attendant that you are not using needles for an illegal use giving him back the plastic mounts ( technically speaking, they would no longer be needles, and en route for the different diameters) ?
Just a path to explore

You know, I do read French a bit, but it's been so long since school that I struggle at it now. I had about 5 years in school and spoke it pretty well, but a foreign language is like math, it leaves without practice.

I plan to hit the drug store and see if they'll sell me some insulin needles. I'll take my model with me so they can see I'm not a junkie.

I guess people have always been like that, but I guess we can always hope for improvement.

Madda, a little french expression more : " Ravi que cela vous plaise" which could translate : " I'm glad you like my posts ". As for different ways of thinking, we had evidence long ago that scarceness of means didn't eradicate any need, and this is most general philosophy. Charles Henry Samson, the man who cut the head of Louis XVI, of Robespierre and of many others said : " Quand la folie des hommes est décidée, elle ne reste jamais médiocre" ( When men's foolishness is decided, it nevers stays mediocre ) . So for addictions. If I understand well, needles are forbidden, but not steel tubes out of their mounts, right ? So the evident answer is : go back to the source and maybe you could make a joint buy, for those who dwell in USA . My neeedles come from either Kendall which is a british company or from Terumo which seems multinational, if this can help.

PS Another little story about different ways of thinking; the other day, I was looking after the Robert Mikesh's book at Monogram Publications " Japanese aircraft interiors" and I found one on ebay but I could not even see the final auction, not saying I couldn't bid, for a clever European Administration Office head ( or maybe a clever French Administration etc...) decided that the view of this book could awake my inclination to racial hatred, when I could buy every book on nazis concentration camps I could want to; we even had an University teacher in History who was a negationist, but no Mikesh book for poor little Torio.

RifRaff,

I wouldn't use that Dremel on plastic. Only use the MiniMite on plastic. That Dremel is great for everything else though.

Dave

those are pretty cool looking mike. later.

I hope you will forgive my rudeness as I ask you this : am I right when I think you have great difficulties to find needles to make cannon barrels out of them ( or anything else ) ? Let me tell you a little story : twenty years ago, I made a little guitar repair for a living ( and it worked so well that I had to get a job in Public Administration, and here I am; maybe I was not good at this job, but that is another story) and I needed a syringe to inject white glue in a crack on a guitar neck. So I went to the nearest "pharmacie" ( it's the french word for drugstore) and they looked at me in an odd way as they must have thought that it was heroïn and not glue I was going to inject ( okay, I came from my workshop and was not wearing my tuxedo, but...) So when you wanted to inject heroïn this time, you had no choice than to share your syringe with other addicts ( not me , I was only a white glue addict ) and you could eventually catch a number of diseases including AIDS, I fear. Nowadays, maybe for this terrible reason, you can get as many syringes and needles you can afford; I buy them by boxes of 100 needles in a medical supply 500 meters from my home and a box runs around 3 Euros. Maybe a path to explore. By the way, Mike, your barrels are very nice.

You know, I'd think the same thing, as would most reasonable people. Making clean and new needles available would really cut down on the transmission of some nasty diseases. However, we have the war on drugs here, and the people behind that have decided that if needles weren't available to drug addicts, they simply would stop using them, so it's extremely difficult to get needles now, unless your'e a diabetic, which I'm not. In fact, if I remember correctly, having needles may be illegal (misdemeanor), as they're paraphanelia. I like your posts Torio! Drugstores here are sometimes called pharmacies as well.

I have this one,> and a regular one with no speed control. I have a bunch of scrap styrene sheets from a recent job. So I'll definitely be experimenting in the near future. (soon as I finish painting the Brad seats)
-Cheers

Riffraff,

If you want to use a Dremel for plastic, get a Dremel Mini-mite. If you use it at a low setting it won't melt platic. I don't know if you can shape with it, but I do know that you can cut with it. You can probably shape with it as well though.

DJ

Oh, right. I didn't think about that. Thanks Mike.

Spencer,

Those are the same thing as I have I think.
The model that I mentioned earlier is 1-1/4" in diameter and mine are 15/16" which is the same as the ones you just bought.
They don't have a grit rating because they are emery cut-off wheels.

Mike

Thanks Mike, I just got back from Wally's, bough a package of 36 for $4.97. This kind...

http://www.dremel.com/productdisplay/bit_template.asp?SKU=409&Color=CC0000

Probably the same. (36-pack) These are the ones with the RR modeler on the Dremel package. So we'll see. They don't really tell you the grit # on the package other than Reinforced or Heavy Duty, etc. I guess these are probably finer going by the other package pics. lol You'd think they could be a little more specific wouldn't you? The only sanding discs they had was a package deal, $11.97 for a sanding pack. Luckily, I still have a few sanding discs and some other bits that came with the original Dremel purchase so I should be able to get it done. Thanks -Spencer

QUOTE: Originally posted by riffraff247 Thanks a bunch Mike. I guess I'll just buy the 20 pack (or whatever amount's in there I can't remember) at Wal-Mart. There is one with a picture of a guy cutting some model RR track. I guess those would be the ones. I can't find a pic of that package, but here's a link. Could you let me know the number of the particular ones you use? I'd greatly appreciate it.

The ones I used are similar to the #540 cut-off wheels.
My "Dremel tool" is from Sears and has the Craftsman name on it so the numbering for the parts is different.
The package I have of cut-off wheels is Sears No. 25024 and there are 36 to a pack.
The sanding disks are Sears No. 53084 and they are Med. grit and also in a pack of 36.

Mike

Thanks for the info Scott. I'll probably try both ways and see which one I prefer.
