Are you just trying to run up your post count? Just funnin' with ya!

I can't imagine why it would make a difference, so long as clearance is not an issue. I'm looking forward to an answer from someone more knowlegable than myself!

The balance scale can be made from scraps and costs next to nothing. I use it for every batch of epoxy.

You still have not told us what you are building...

Don't you just use duct tape?

FWIW, I will join my wings and center spar and THEN mount them into the fuselage. There seems to be a number of advantages to doing this. One, for me, is that I still need to get my parts out of the basement, so the landing gear, wings, canard, spar and headrests will all have to go as separate pieces. I'll assemble them out in the barn.

And then there's the OTHER tan stuff that crumbles into dust if you look at it wrong...used for thicker buildups and is very easy to carve. I can't remember what it's called. Basically the consistency of the foam used by florists.

True, but if I'd ponied up the money for an RV kit I'd have been flying a year ago instead of looking forward to another 4 years of building.

I save samples of some of the layups that get cut off so I can look at them. One interesting piece of scrap is the portion of the fuselage you cut off when making the cutout for the canard. In one piece you have portions of the longeron, some blue foam, some yellow foam, several layers of fiberglass - good for "show and tell"! Probably useful as part of your project's documentation too.

BTDT! Also best not to push yourself when you are tired or when you have other things to do following a layup - like anything that has a set time. Several times I've started a layup thinking I had enough time before having to go somewhere, only to find myself up to my elbows in epoxy and still needing to shower and shave to make a dinner reservation... Good thing nice restaurants turn the lights low...

Thanks for the reply, but the issue is figuring out where to put the hardpoint for the 4th hole, since it is NOT in the plans. Even with Jack's mount in hand, you still don't know where the 4th hole needs to be until you assemble the parts - and you really can't assemble the parts until you make the hardpoints and complete the glass work. There's just no good answer to this problem - it's kinda circular. Don't know where to put the hardpoint until it's assembled, but can't assemble until the glasswork is done, but the glasswork can't be done until you have the location of the 4th hardpoint... I'm almost ready to put it together, so with luck my guestimate for that elusive 4th hardpoint (only 3 of which are needed) will be good enough and I won't have to do a patch job. But if it's off, then I'll make the repair and quit *****ing about it. If I had built the manual gear extension and then done a retrofit of the electic gear we wouldn't be having this discussion apparently.

My best guess is that folks are using their NG-51's to locate the holes/hardpoints. All of the holes are not there, as numerous other builders have had the same question. When I searched the archives I found this from you, in reply to another builder: "My measurements show that the fourth hole (the lower one closer to F-22 on the pilot's side of the fuselage) is approximately 4" forward of the rear surface of F-22 at a distance of 2-5/8" from the upper hole. It's NOT directly below the upper hole, but slightly in front of it. If you make a 2-5/8" circle around the upper hole and then intersect it with a line perpendicular to F-22 at 4" from the rear surface, you've got it." So that's what I used to approximate the location for that hardpoint. I'll drill the actual hole after the assembly is complete. With some luck it will be within the hardpoint. I'll look at M-19 - I haven't looked at that one yet - but M-10 and 11 do not show where the middle hole for Jack's mount needs to be.

Hallelujah! Jack's kit does indeed include a very nice pair of NG-14's! I would not have found them until after I was done if you had not told me, as they were in the bag with the wire harness and I had not taken it out yet. THANKS!

YAHBUT...the locations for the holes are NOT in the plans. That's the big frustration. They ain't there. Best you can do is take a SWAG and hope you are close. Take a look at the plans. If there was even a drawing of NG-51 this would have been easy.

That makes sense. Once I determine the location of the holes for the electric retract supports I'll adjust the hardpoints as necessary and fill them up so they are flush with the surface of the NG-30's. Thanks for the replies!

Looks like mine is the same.

Here's a picture of mine, showing (I hope) the cupped shape.

Well I guess I need to take another look in the box. I had no idea they were included in his kit. Thanks!

Where do you buy those? Radio Shack? TIA!

I would never rely on the attachment glue for anything I cared about. I use the plain, no-adhesive click bonds and attach them per the excellent drawings on the CozyGirrrls site.

I considered doing that since I had a piece of phenolic that I was not going to use. Did you taper the sides? I figured that if I tried to cut the 1/4" phenolic circles at an 45 degree angle it would be hard to do, but if I didn't do it then there might be a shear condition with straight sides...? Anyway, I already cut the 90 little bid circles, so I'm hoping I will not have to do these over. I just have to decide if I want to use the larger washers with flox under them or use smaller washers that will actually fit in the hard point depressions.

I did the layup as stated in the plans, and weighting the layup for cure did not even touch the center of the hardpoints. They simply do not fill up the hole, and so my hardpoints are like little "dishes" - just like the drawing in the plans. It just seems odd to me that the other drawing shows the washer inside the hardpoint "cup" and flat on the bottom of the hardpoint. I could use smaller washers and do the same, or fill the "cup" with flox to avoid the gap under the "bridge". That might make the bolts too short, though...

The bolts I bought are AN4-21 and I got the high temp locking nuts. The wheel is two halves, with tapered roller bearings. There are three bolt holes with no threads. The AN4 bolts are a good fit - no slop. I put the inner tube into the tire and added a little air so that there would be no wrinkles. Then I put the two wheel halves together so that the valve stem went through matching half-circles in the hub and out through one of the wheel halves. Then I used a couple of C-clamps to squeeze the wheel halves together and inserted the bolts and started to tighten the nuts, working around the wheel so that it came together evenly. If there is still some concern, I'll try to remember to take a picture and post it here. Thanks!

I guess that AS&S's chapter 13 kit has the wrong stuff? 1015/1020 BUSH STOCK 3/8 X.065 3003-0 TUBE 1/4" OD X .032" W 4130 STEEL TUBE 5/8" X .058 are the materials listed in AS&S chapter 13 kit. Can you please tell me what I need to order to have the right material?

I have Jack Wilhelmson's noselift kit, and it's pretty neat but would be so much better if a drawing of NG-51 existed either in his plans or in the Cozy plans. This is needed so that you know where to put the hardpoints and are not making unneeded hardpoints as well. I'm hoping I got mine close enough that I will not have to cut up my NG-30's to make new hardpoints... On the subject of the hard points - they end up being "cup shaped" because the 15 layers of BID do not completely fill up the holes. This is even evident in the drawings in the plans. So my question is - do you fill them up with flox? As it is, the washers called out in the plans bridge the hardpoints, leaving a hollow area under them - that doesn't seem right, but I'm no engineer...just a poor guy trying his best to follow the plans... Any guidance would be appreciated! TIA!
