Hi Paul;
When you are done playin around with that Delrin and Aluminum you have now and wish to move up a notch to bigger stull I will send you a piece of this. 5.25 diameter X 24.00 long 7075 T3 Aluminun. It may take you a few days to turn the OD to size but you will get plenty of Lathe hands on experience. LL~ LL~ LL~ LL~ LL~

Hey Gruby,
T3 aluminun ::) --- is this a new kind of alloy??? Maybe your spell check is broken!!! LOL ;D
-
T-3 is the state of hardness of the metal. -0 is soft, T-4 is solution heat treated, T-3 is solution heat treated and cold worked. 7075 is usually T-6.

Bill,
You can laff, but I used some of that stuff to turn fancy waterpump pulleys for my flathead Ford.

Phil
John ; sorry about the Typo nice catch
Garf; you are correct it is usually T6, this was special order for easier machining.
Phil; no way will I laff, I've seen this used for lots of different things. This particular piece is for front and rear crankcases on an 18 cyl. radial engine I am going to build starting in November. VD~

Eighteen cylinders... On a Twister. I'm excited already. Hmmm. Dope over dyed silkspan. Very cool.

Clayton;
That might be a cool project except the completed engine weighs in at 18.75 lbs. Wing loading would be a problem for sure, then there is the arm loading. LL~ LL~ LL~ LL~ LL~

Bill, how big around will it be.

Bill,
The amazing thing is that you can legally build and fly that engine on a model over 55 lbs with waiver and even compete with it . Some of the IMAC models are up to 30 inch props. That is ulltra light sized for sure
Basically the 18 cylinder would be cool on a model of the corsair that They did install one on for evaluation.
If you build it I'll pit for you. H++l I'll even hand prop it for you.

G-Man,
I have not had a chance to get over to my dad's house. It will take me a few hours to figure out just what I need to do. I need to figure out how big to drill the holes for the venturi's and it will take the better part of a day to get everything gathered and setup.
Ryan came home this weekend, and next weekend we have plans, then the next weekend I will be driving back from some place in PA.
Seems like that would make a venturi for you BA RM? LL~ LL~

I predict a bigger,maybe more stealth,Sooper Dooperer Ringmaster on the horizon! But better get the SDR finished first big bro! LL~

I have to get all the irons out of the fire before I can start this project. I can't jump from one to another. As you know it will take about 2500 hrs. to complete. 1 yr. at 40 hrs./wk - 2080 hrs. I'm 64 and no way can I stand in front of a lathe or milling machine for 8 hrs. a day anymore. LL~ It will get done however long it takes. This is my last big project.

A proposed schedule:
Finish all the parts by Roundup 2012.
Bring the parts to the Roundup 2012 and we can then ALL help you assemble it!

I said that with a straight face?

Clancy you don't know what a straight face is. LL~ Estimated assembly time once all parts are made 51 hrs.

That's going to have to be one big ringmaster for this thing. I want to be there for the first flight of the Ringmonster.

A 96" span Ringmaster Biplane comes to mind Phil. S?P S?P
