don't forget the bleed screw on the top or you will hate yourself about 15 minutes into the break In run... I also used a turkey baster with a length of hose on it that I shoved down into the RV tank inside the hose that comes off the top side of the engine (bottom of case if inverted) and sucked the oil through to assure no bubbles were hiding in the cavity.. Then the tail in the air spinner on the ground for about 10 minutes to really make sure all the air had migrated out of the cavity. Yes I was a bit anal about bleeding it on round 2.
Looks like I will be at OSH April 17~21st attending the EAA leadership workshop. Going to have a little time to kill so I am tossing this out there to see if anyone will be around the area that wants to get together to have some drinks and lie about how good we once were
Paul I have not yet added it all up. I think weight gain will be minimal versus the stock Avid "wide" gear. A couple pounds would be my guess. I have a set of stock wide gear I can weigh and then I will weight this when I am done. The fun part about experimental stuff is that I can build a set of struts for the bungees and the springs and use on the same plane, same gear so I can test out what does what best. The challenge to build a better mouse trap excites me more than hohum building parts on an assembly line
TJ, I looked at the streamline tubing. Piper does this I know on the PA20 gear for the bungee strut but that is more of the stock Avid KF bungee style I am trying to get away from. FWIW, I have repaired a few PA20 seat trusses for the exact same reason we have to repair them on the Avids and KF. Hence most people that use the PA20 for off field work go with the supercub gear STC. Glad we don't have to deal with STC's here!
Just for giggles I looked up Spencer and compared prices on my last few orders. Some items were a few pennies cheaper, some a few more (versus spruce) and all in all it seemed to be a wash to me. I would think in a case like this it comes down to customer service.
UPDATE.. I got a surprise phone call from Jack with AC Spruce today.. Seem they do keep an eye on the forum and he was handed a print out of this thread. Jack called and explained the hose up and credited my account. Not only is this a one time credit, I have been instructed on how to make sure this does not happen in the future as well. I was pretty surprised that he took the time to call and make things right now and in the future. My take away is 1) this lil forum is getting attention of the suppliers etc and they really are trying to do the best they can to keep people happy. 2) If you are making a small order don't do it on line, call it in and request the flat rate boxes. If you have issues call and tell them you want to speak to Jack!
I am pretty sure you guys have figured out by now that I am straight up and have no problems calling a spade a spade and I am not one to give out praise too easily. Jack really gave me a feel good today about the big guy listening to the little fish in the pond.
There is no way in hell I could have gotten the bird up to 60 without pulling back on the stick.. He has some serious self restraint! Cool project, can't wait to hear flight reports!! I thought long and hard about dropping my foot wells down like the airdale on mine. It is still and option at some point in time.
That's a possibility. I think its over kill if designed right, but adding the 3rd leg is not a big issue. My plan right now is a 1 1/4" front leg and 1" rear leg with a couple braces in between. I have also been drawing it up for 1.25" axles (cause that's what I an running and they don't bend) but I can easily make then for the bend prone .750" axles as well. I have wheels and brakes for either set up, I just like the larger axles as chances are guys are looking at bigger tires etc. If you get the matco wheels that are 1.25" axles and use the 27" desser tires then you should have about the cheapest most robust set up you could bolt on to these birds. Of course, you could go with the TK1 gear and struts etc but I think that has its own set of issues as far as dinging the shock then loosing your air and having a flat strut. That is harder to repair in the field than a bungee or spring. Not to mention, the cost goes up quickly as well. I am trying to work off the K.I.S.S. and have a real gear that wont bend your bird under normal to heavy use but wont break the bank either. Putting 7K worth of gear and wheels on a 10K bird seems kind of dumb to me
I will consider anything someone wants to use. That's the good part about doing custom work, its tailored to the individuals wants or needs. Once the basic jig is made just changing out the suspension strut is easy and only 4 bolts. I was just trying to keep costs down as everyone seems to balk at spending money these days The tooling I am about to order is a substantial investment so I will be fabricating a lot more than airplane parts with it. Roll cages, roof racks, wheeler racks boat hand rails etc.
