Any reason why you couldnt ask for CNC work on helifreak? Doesnt mean you gotta mention HeadhunterHelis.
And when I get mine I should post a nice long thread with pics and all, then play dumb when it gets closed.

I love Helifreak a lot and I don't want to lose my posting privilege there. Sincerely. I can and will ask there. I don't see a problem with posting pictures of the helicopter there.

Speaking of CNC milling... I'm investigating some off-shore work with American made alloy. I don't know how this will turn out because most companies, as I have learned, do not want to setup for small runs.

Scott, I will try to do some more checking around here again. I remember asking a few people I know that either work at, or own machine shops when you where trying to find someone before, but I didn't have much luck.
Most of them did not do 'piece' work as they mainly built machinery, and others wanted a small fortune to do the work.
I will see if I can get a hold of one of my mom's uncles as he used to teach building maintenance at the local Vo-Tech school, and he likely knows the current machine shop instructor there. They might be willing to do the work for free if you supply the raw materials, I dunno. I will try to find out. It is much harder to get the school to do "outside projects" lately as they do not want the liability risks.
Hell, when I went to the local Vo-tech, I was in the carpentry class and we built the city's new clubhouse at the golf course, and did lots of other projects in the county, but they shy away from those things now.

Thanks, Jerry. The hard thing is going to be getting them do it in small lots. Please let them know that.

I've been in contact with two machinists in the states whom I've sent drawings to for estimates. I'll keep you all posted on the results. I'm not giving up.

I was just looking at some photos of a Henseleit TDR and I'm pretty sure I saw some pieces that were delrin plastic. Not bearing holders, but things like boom clamps. Maybe you could make some of the frame bits out of delrin?

LOL! I just want to get metal parts. I'm very close to getting samples from my new machinist (actually aeronautic engineer). There will be good things coming, I promise.
Scott
I would really like Delrin gears.

Hey Scott, Any recent updates on the progress of the HeadHunter frames? Inquiring minds want to know, lol......... And I am sure that I am not the only one.  Jerry |

Okay... here's the deal...
My machinist, the aeronautic engineer, has cut and tapped all the samples except the stainless steel plate for the motor mount. I expect him to have the samples to me shortly. Once that's done, we'll get production going. He sent me pictures and they look good, but I won't know for certain until the samples arrive and I test fit them in a frame. I sent him the frame halves for his testing and they work there, but I need to test a complete build before I sign off on them. I don't expect this to be a problem because this guy is GOOD. All parts have had stress testing profiles run and have been modified for greater strength. Not that the originals were weak, but these guys are going to be uber tough!

That is good news bro. Once parts production begins, that will be great news. I am filing my federal income tax return this weekend, so, I will be ready when you are.  Just not sure how many frame sets I want yet once you have them ready. I have 3 plastic framed Hurris, but my HH framed one is my favorite. |

Great, Jerry. I'll be certain to post here once I get the production parts in stock!

I'm happy to report that I have test parts to check. I have physically examined them so far, and the quality is there already. Rob, my new friend and aerodynamic engineer did an OUTSTANDING job on the parts. I would have no problem selling these as they are, but I'm psyched that the production parts will be even better! I'll report back here after I test fit the parts tomorrow. I'm anticipating from here on in, we'll be good to go.

LOL, Jerry! About time, eh? Scott I have been patiently waiting, knowing you were working hard trying to get parts made. Of course, I was luckier than some of the other guys that have been waiting since I was able to get my first HeadHunter frame before you ran out of the original parts. Next frame will be for my original 425, then, maybe someday one for my 550 too. It's carbon fiber 'porn' , lol......  Let me know when those HH ball caps and T-shirts are ready. Jerry |

I have to tell you, the bearings fit perfectly into the blocks. All the parts fit perfectly. No do-overs! And as an extra benefit, here's a quote from Rob... "The metal will be treated using a process that is used in high-end car racing, so that it can tolerate stress reversals much better. But, all of the 6xxx metals are very sensitive to heat above 350F-ish. I can send you cutoff values for your customers, but they have to be very careful to not exceed those values when cooking out green loctite etc if they want to retain full metal strength." Rob is big into car racing and is an aerodynamics expert. I hope to be working with him for a LONG time. Scott |

Rob is big into car racing and is an aerodynamics expert. I hope to be working with him for a LONG time. Scott A little off topic but, I worked in an aluminum extrusion plant for almost 12 years. Based on my own personal knowledge of extruded aluminum alloys and tempers, I would not be too concerned with reheating an aluminum part that was produced in an extrusion process, so long as it was water quenched and then heat treated. Sheet/plate or cast aluminum is a whole different story. Depends on what type of aluminum is used for the parts. |

Well, I'm not that well versed. I will have to ask Rob what process this is. I know it's not cast.
