Can somebody get me the measurement from the wing tie-down points to the floor?  I’ve had it on my “to do” list to get a set of wing jacks but am out of town at the moment and would like to get them ordered.  

   

Thanks.

I went to measure mine and discovered that one wing is an inch lower than the other.  I had not noticed it before but if you make your jack 28” you will have 1” clearance to the ring (29” on one side 30” on the other)

Actually, I'd avoid making them all the way that tall if you can.

The jacks I used are 24", which makes it so that if you lower them,

you have less of a chance of running the wings into them if you roll

the plane in and out.  I usually leave mine  parked under the wings,

out about 2' from the end so you don't trip on them.  Then they're

ready for use without lugging them too far....and they clear

the ailerons if they are down when you push the plane back.

The 20" stroke gives it all the reach it needs.

Where are you looking to 'get' these from?



I've been surfing for them a bit and can't seem to find what I think I'm

looking for.



I'm thinking about a tripod type stand looking thing with a bottle jack in the

middle - or some reasonable facsimile thereof.....

Buy the Harbor Freight tall bottle jacks and make your own 'stabilizer' out of a foot square piece of steel.Â  Flatten the ends of suitable lengths of 1/2" EMT and use pieces of angle iron on the base corners and at the upper end ..... large hose clamp to hold the upper end or make a huge ''washer" to attach the angles to.Â  Be sure to label "experimental"!!!

Just as a caveat.Â  Some but not all of the Harbor Freight units have a history of a slow bleed of pressure.Â  Some places prefer a locking method to insure the aircraft does not come down without intention.  

   

For the quick, down and dirty on a RV-10 budget, they often work fine.

Mine will stay up all week with no leakage, but good point.  If you

have any super critical maintenance that would cause the plane

settling slowly to make major pains, you may want to attach a locking

collar or build a stop-shaft that would prevent the plane from going

down any further than a certain point.

 This is true.Â  If you get one that bleeds down, just take it back.Â  If you've had it a long time and it starts to bleed down, unscrew the shutoff part, and remove the ball so you can inspect the seat.Â  I've found metal shavings pressed into the seat ..... probably because I was trying to stop the bleed down by really torquing down that screw.Â  I've also found seats that looked like a chip was missing ..... like a drill bit stopped and pulled a chip free instead of shaving it off.Â  Fixed that one with a drill bit and polished with valve grinding compound.Â  

 

 It's a whole lot easier to return the jack!!!

I don't know. Folks will spend $600+ for a pneumatic squeezer, but don't want to spend ~360 for a good pair of jacks. Aircraft GSE makes some really nice ones for about the same as Jack House and others.

 http://www.aircraft-gse.com/lw-3.html

 If you only need one for tire changing, you can do that too, for under $200.

 I don't want a 1600lb plane falling on me from a homemade jack.

 YMMV, BWTFDIK

 True .... but they'll use the squeezer far more often than the jacks.

 You obviously know you can't hold up a 1600lb airplane by yourself!!!Â Â Â Â  But if you've already spent $600 for the squeezer, $60 for two jacks plus some steel and time is really easy on your wallet.Â  Not to belabor the point, but we (the collective 'we') build things, and are just as capable of making safe jackstands as anyone else.Â  

 

 The storebought jackstands do have the spring-loaded wheels which makes it much easier to move around.

You will use that pneumatic squeezer a whole lot and it will make a lot of tedious work very easy.  Jacks on the other hand would be used by a pilot owner MUCH less often.  And after all, you would be flying a "homemade" plane, why should you have less faith in your "homemade" jacks?



Aircraft jacks for $360 for a pilot/owner (not a maintenance facility) makes about as much sense as those powered aircraft tows for $2,000 when a good new John Deer tractor with a tow hitch can be had for around $1,500.  At least you can also use the John Deer to plow the snow from your hangar entrance in the winter and oh yeah, maybe mow the lawn.

Probably heresy on my part, but after the build is complete, you will

hardly ever use that squeezer, and could easily sell it to another

builder to more than finance the single jack you need for tire

changing and have enough cash left for a hamburger run or two. And

just as we all choose to build and most choose to do their own

maintenance, for the years I've owned a retract plane, I saved far

more doing my own gear maintenance a single time than what the jacks

cost me (got a special of $300 for the pair). Lessee, $360 is what

percent on a $150K RV-10? Compared to a single hole punched in a wing

from a jack failing? Or an arm caught under an axle? We all make our

choices for our risk tolerance and pay our money. No one right choice,

just offering an alternative point of view.

Will make good on Kelly's prudent offer to finance Jacks by sale of Squeezers.



Interested parties, Contact me at (503) 453-6016. I can always use a few more pneumatics and have lots of clients looking for squeezers.  Boeing Surplus went south on us "out here in the West".  I encourage active, cognizant jack operations.  Have a close friend (and A&P instructor) who lost a wing spar on a twin Apache by use of a cheap bottle jack while using student labor.  It failed the gear retraction test as the jack remained mostly upright after a slight loss of position, until it destroyed the spar. Ouch!

I think the 'student labor' was probably the operative word.  I agree 
	


that improper jacking is hazardous to your airplanes health.  I saw an 

airplane jacked up for a retract test, teetering on the jacks with the 

tail tied down with rope .... and the A&P climbs in to pull the gear 

up.  The whole airplane slowly rotated and settled on the wheels ..... 

cockeyed in the hangar ..... and couldn't be rolled out! 



You need three points jacked firmly up for stability, and the jack bases 

need to be large enough so they won't tip.  If you're going to use the 

tail tiedown ring ..... use a metal tub with concrete in it and a pipe 

sticking up .... with an eye or hook on the other end.  Prevents the 

tail from swinging.  Three solid points almost guarantees a good, stable 

lift.  The type of jacking points on the wing are also critical.  

Whatever you choose, inverted cone (ala Piper) or a pin .... whatever 

... needs to fit the top of the jack too.

 	  Quote: 	
		     It failed the gear retraction test as the jack remained mostly upright after a slight loss of position, until it destroyed the spar. Ouch!

   

I watched a 'crew' of hangar rats try to lift a Baron off the runway 
	


after a gear up landing ..... you know the 'expert' types ..... and the 

plane slipped off the jacks and .... fuel tank developed a large 

leak!!!  I watched because nobody would listen .....



John's correct ..... jacking your aircraft is an unnatural act and 

should be approached with caution ..... but like anything else the 

operation can end up in the toilet if you're not careful.

Wow, who would have thought that a simple question would have generated so many responses- thanks Gary for the specific data!



I appreciate those that suggested a variety of approaches to jacks (both online and offline).  My issue is that I have been out of town a LOT lately for work and at this point I just don't want to use the little bit of spare time I have to build jacks.  I ordered a pair from JackHouse and should have them early next week.  



An interesting observation about the wheelpants & gearleg fairings is that most people focus on the speed increase.  Another major, but unspoken, benefit is that you get significant increased cooling from the extra speed/airflow at the same power settings.



Thanks again to those that responded.

Hey Rick,



Now that you're this far along....give your opinion as to how your views

may or may not have shifted on what you feel the "average" builder will

put into their RV-10.   What was your original budget and thoughts,

and how did that come out?



For me, I probably ended up 40-60K over what I originally intended,

starting out and allowing creep as I went along.  Just wondering

if you have a perspective change.

Well, I just saw a kit for sale on airport bulletin board...everything

except avionics from what I could gather, and definitely at the

finishing stage, for asking price of $100K, including new certified

engine and lighting installed.

So I just threw a figure out there I figure could be achieved with

Van's theoretical VFR machine...not the panels that out do Cirrus et

al. I know that many folks are pushing or exceeding 200K. Just didn't

want to look like I was inflating figures.
