Darrell, I plan on bringing it on the 13th. Hope the weather is nice. Looks like wind forecast is out of the North that day. But, that's OK.

After taking the UV-20A out again recently, I decided the gear was just too weak for this bird. Am making a new gear out of 1/4 inch piano wire, which is insanely hard to bend! Plus, will find some stronger springs for the struts. Had to buy a new vise to put the bending jig in and then bolt it to the work bench. I managed to bend the wire, but it's tough, I tell ya. K&S doesn't make this jig any longer, so, glad I bought this one 21 years ago at Roy's. Bent one half of the new gear and will make the back half next. Always something to repair.

The new gear will attach slightly different from the old gear. The old gear is lots harder to duplicate as it has more bends.

Made some progress on the Porter gear. Bent both halves and got them soldered together. Very solid! Still more work as I need to beef up the internal fuselage sides with 1/4 inch plywood. This is where the spring struts come thru. The factory design on this was just about worthless.

Kept going into the day! Made some hold downs for the new gear out of large steel washers. Drilled and countersunk them for drywall screws. Seems to work nicely. Will use JB Weld to bed the wire into the mounting blocks to really secure them. Soldered the joints again after filing them down to make sure they were really soldered properly. Scrubbed the liquid flux off the joint with cleanser and washed in hot water. Painted the gear in rattle can polyurethane.  Going to work reinforcing the fuselage sides next, where the spring struts go thru on each side. Should have it all finished soon. Just in time for more days of 105 Deg F heat! Haha.

Got to the fuselage repairs today. Got the left side repaired and improved. That was the side that had the damage. I cut a 2x3 inch piece of 1/4 inch plywood to epoxy on the back side of the fuselage. Had to cut thru the instrument panel to get that large piece of plywood inserted. But, once back together, won't be that noticeable. On the outside, I soldered a steel washer on the upper spring strut to keep it from pushing thru the fuselage side. And behind the washer is another piece of plywood I made a disk to cover the overall hole and to add to the whole impact area. Won't look so bad once painted.

Pretty much done with the repairs and mods, so, it's a matter of cleanup and paint touch-up. Added a dowel across the fuselage to really keep the fuselage sides from pushing inward under the stress of the struts being compressed. Barry, this dowel is one of your suggestions the day we flew her.

Good work   Now she’s ready for a hard landing. Hopefully we won’t have to test that. Ha

Got the white out and sprayed a couple of coats on. Letting it dry overnight. Then the black anti-glare panel.

Last thing for today - installed the gear on the mounting block. I bedded it with Hysol and that takes around 18-24 hours to setup in this heat. Longer in the winter. I was going to use JB Weld but since I had plenty of Hysol I used that. Hysol is likely as good or better than JB Weld. In this application  anyway.

Got all the parts back on and she's ready to fly! If the temps will go down, that is.
