.12 tune pipes

[Glenn Quarles]

Hey guys. As I was sitting around the house this week recovering from shoulder surgery I got tired of looking for a .12 pipe that had the angles, volume, etc. that we've been looking for so I just decided to make my own. It turned out to be really easy (in fact it took me less time to build these two pipes than it did to figure out how to post this picture!) and I can get exactly what I want. I'm anxious to get out and try them to see how (if?) they work!

Here is a picture of the two pipes. The cones are the same length (about 1/2" shorter than I could make any comericial pipes), but one has a little bigger diameter.

I hope the picture shows up!

WOWSERS! Glenn, you're hitting on something that is badly needed by us that love the .12's.

 

[Glenn Quarles]

Ron, yeah I feel (felt?) your pain. There are a bunch of really good pipes for car motors, but not much of a choice in nitro pipes. Now I just need to get smart on pipe design to figure out on what changes I need to make! It will be fun!

Glenn, the problem with too may 4-wheeler pipes is that they will slap on just about anything and don't really work with the pipes like what we boaters do. There is a site for Michigan R/Cers that I found and I was surprised to find out that they really don't do much adjusting or tuning on their systems. I asked them what kind of pipe length that they ran and how they measure their pipes. Most were clueless! A lot of them had never heard their motors get "on the pipe".

So give us the lowdown on how you made them

 

[TomMoorehouse]

yea.... how did you make them. I once tried to make one by soldering cones of brass i rolled but it was very inaccurate and BUT ugly!

 

[Dorkhedeos]

hrmmm, did you use those bakery things? the metal fittings that attach to that bag? i have a question, how do you know how long to make it and how long to make the cones?

 

[RIGGERMORTISE]

If anyone has a good design idea i am willing to make a test carbon fibre pipe.

Regards.

They're made out of tin plated mesquite, I'm sure. Glenn is good with mesquite, and tin, so they MUST be made of tin plated mesquite. They may not hold up under the heat, but at least your boat would smell like brisket while your tuned pipe melts away.

 

[Glenn Quarles]

Ha, Jason you are TOOOO funny! I made the pipes out of .025 steel that I cut and rolled into a cone and then silver soldered. I came up with the length of the cones by best guessing. I will let you guys know what happens when I run them (may not be until Speed week though).

Glenn

 

[DJT]

Did you roll the cones yourself? If so how?

 

[Glenn Quarles]

DJT, I just rolled them by hand. I clamped a piece of 1/2" (1/4" for the area right around the stinger) tubing in my vise to work it around. It is easy to roll into nice cones...just have to take your time.

I think that Micro Mark makes a miniture roll bender......let me find my catalog....

 

Hey Glenn what type of shoulder surgery did you have ?? I had surgery in Jan. on my left one.......MRI showed the ball and socket was fine... I tore the hole arm and socket off the bone and a tricept muscle and tendon that goes over the top of the socket and attaches to collerbone area ,he had to go almost to my elbow to get the tendon unattached where it had regrown into a musle.....I thought my arm was coming out of socket but it was my whole arm going over and off the shoulder blade..!!!!!!! And I would have to pull it back over the bone and just about passout everytime,it got so bad I could not even reach for anything that it would come lose..... You want to talk about pain!!!!!

 

The final straw was I was out side working on my fishing boat to go shrimping and woke up on the ground and didn't know how I got there or for how long i was there...out like a light....

 

After surgery and I Got home, the muscle would spasm and jerk my arm straight out with my elbow pointing horizontal in the sling , about every 15 minutes........I had to sit in a chair and wedge my arm between the chairarm and my side to keep it from jerking up !!!!! I made him give me some musle relaxers, but that made it ten times worse.... Thank God for the "Oxyconten", bad stuff...!!!! and now I still have pain...9 months later.. M.U.S.C. ~ Medical University of South Carolina made me a movie star by filming the surgery for teaching purposes.. { Berkheart Procedure } very, very, very, very rare....!!!!!! I have screws,pins,and plates holding it all together.. I have pictures of the end of my arm...before and after he cut of the ragged edges... OOUUCCHH !!!!!!!!!!!!!!!!!!!!!!!!!!!

 

And if thats not bad enough,my right arm is the same way!!!!! I've lived with it since the age of 18 ..... I'm 43...............

 

Sorry for the off subject guys..........

 

 

[Glenn Quarles]

Waterbug, dude you have it MUCH worse than I do!!! I just had about 1/2" of bone trimed off of my collar bone at the AC joint to fix it being splintered in a car wreck. I hope to be back to 100% in a few weeks.

If the roll bender can be set up for doing cones it may be really handy. I don't ever see myself making enough pipes to make it worth while, but if someone is having a hard time bending them by hand or is going to make a bunch of pipes it would certainly be worth it.

Glenn

 

[jasonspeedy]

Yeah... I don't know about this whole metal rolling/bending/breaking/AC rotator/shrimp boat thing. I'm still leaning toward the mesquite. Besides, I'm an extreme proponent of the environmentalist movement...and mesquite is a renewable resource...PLUS...if you screw the pipe up you can invite the in-laws over for bar-b-que,no harm done! BONUS!

 

[Glenn Quarles]

Jason, you are such a dork! Your weird sense of humor is really helping my shoulder therapy...the rolling on the floor laughing is better than weights! :blink: Have you got the bouys set up yet? Get to work!

Glenn

 

[jasonspeedy]

I have recruited help for the setting of the bouys, however, I have not begun construction as of yet. I hired an independant think tank to research the possibility of outsourcing the bouy and sub-bouy construction to a semi-developed third-world nation, in an effort to maintain the Valdosta Model Boat Club's bottom line for the current fiscal year. By the way, is it hard to maintain a negative balance? If so, I should get a financial grammy or something. We have done very well in maintaining a profit margin of about 0.0% At any rate, I will be very ready for speedweek II. This years batch of friction inhibiting suspended teflon is scheduled for delivery by Thanksgiving, and I've nearly completed installation of the 13 acre roof. Best of luck. JOB.

Jason, while you're at it, have the crew work on the 36 degree banking in the corners! :lol:

Roofing??? Banking??? thats just silly!!! What about a 'loop-de-loop'?

 

[Shnick]

Hey Glenn, bring those pipes over to my house and we can shine them up on my NEW LATHE!!!!!

(But don't tell everyone)

lol
