For the hinges I use some CRC spray lube, or something similar. I haven't found anything that won't attract dirt, especially in the desert. Maybe Larry Cottrell will chime in here with his expertise. He is a "real" desert rat. I don't know if I have a "bigger or smaller home built". An RV8 is 24X21 and a MKIII is 30X23.5. Yet a Bearhawk is 33X23.5. I am in a dilemma. john h mkIII Crawfordville, FL On bigger homebuilts, the recommendation is a non-greasy lube, so it won't catch & hold dirt in the pivot points.

For all the alum hinges, I use dry-moly lubricant, like what they sell in the bike shops for the insides of brake cables. The dry lubricant will not collect dust and dirt. This is important for your hinges (which are aluminum), because grit in the hinge will quickly wear away the metal, with the constant motion of a moving hinge.

Hello Kolb builders, I have all my surfaces ready to cover. I have laid out my wings flaps and ailerons. The only thing I have not done is drill the holes to test mount the hinges. Is there any reason I could not wait and drill the hinge rivet holes once everything is covered? Thanks as always for your thought!

From: James Beard Nick... I'm not certain why, but the constr. manual calls for all 1,000 holes to be drilled & deburred prior to covering. This also allows you to clean out all the drilling debris, probably a good idea.

Nick: I find it much easier to trim the hinges to fit, drill all the rivet holes in the hinges, then fit, adjust, and drill all the holes in the spars using the predrilled hinges, secured with Clecos, as a template. When I finish covering wings, ailerons, and flaps, I use a pencil tip soldering iron to open rivet and drain holes. After Polybrush, I cement the gap seal, complete processing the wing through finish paint. Finally, I rivet the hinges to the wings, flaps, and ailerons. Makes a much finer looking job. john h mkIII Crawfordville, Florida From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of Nick Cassara Sent: Thursday, October 16, 2014 12:10 PM Subject: Kolb-List: Question for the builders...

From: "Rex Rodebush" I agree. Drilling the hinge holes with the fabric on would be a real mess. The hot solder iron trick works great. Caution: When I covered my flaps and ailerons I went too far with the heat shrink and bowed the leading edges. Not a lot but enough that the hinges could not be installed. Had to recover. Just watch the L..E. and when it just starts to bend...STOP.

I'd drill em now, just use aluminum rivets in every 6th hole or so to hold t hings aligned as you drill, than remove and deburr before covering. Than bur n out the holes in fabric with a solder pencil before you paint while you ca n still see the holes. If you drill after you cover you are going to be patching holes.

Nick, My firefly was a quick build where the factory had already attached all the hinges with temporary rivets. All of the other rivet locations had a "dimple" where the holes were to be located but they were not dilled out. I drilled out the temporary rivets so I could use the drill press to finish the holes in the hinges. I then waited until all covering and painting were done before drilling the rest of the holes in the airframe, using the now drilled hinges as guides. As I covered, I kept the holes cleaned out, so they were easy to locate later. Although what I did worked out well, I kind of wished I had drilled everything before covering. I think it would have made final assembly easier. One think that I do regret is when I put the rudder half hinges on the rudder laying on the bench. Then I mounted the tail post halves on to the airframe separately, thinking I could just line up the hinges and drop the pins in place. I had done this on the wings with no problems, but on the rudder, for some reason the lower hinge would not align without a LOT of force on the rudder. I wound up slightly bending the bottom of the rudder and put a wrinkle in the fabric. Did not even notice it until it was all done. L My take is to pre-drill all the holes and be VERY careful with light weight structures. Worth what you paid for it..
