    I cut and re-welded the master cylinder mounting tabs on the pedals to get better leverage and I can now hold the plane at 4500rpm without creeping. I think it will get better as the pads bed in on the rotors. I am happy to have brakes that work finally.

    I got a couple more pictures. Weather has not given me a break here to get anything out of the hangar so I pulled forward as much as I could.
    I am going to try a small iron one more time before I start cutting. I am also going to set a 4' or 6' level across the tails of the ribs on both wings to compare and determine if it is bent upwards because it is still pretty hard to tell.
    i also happen to have a pair of Kitfox fiberglass droop tips. I wonder how that would affect the performance of my Avid Speedwing. They look like they would fit although it would reduce span by a few inches.

    I took these 3 pics real quick while I was at the hangar today. I will have to pull the plane out to get better shots. I am not sure if I will have time to get over there tomorrow or not. Maybe Friday. It also depends on the weather. We have been having daily storms and I believe they are supposed to continue tomorrow. I don't want to pull the Yankee out in the rain.

    Fabric covering is a pain but I can do it. The custom paint is what I was trying not to mess up. The cable does tighten up when the tip is pulled down. Maybe that is the answer.

    Another concern is with bending up or down. That is at the tip of the wing so if it is bent up or down more than before it will probably act like a big trim tab and cause a slight roll left or right when I let go of the stick. It already had a slight roll to the left so bending this tip down could make that worse. Of course I won't know until the first test flight after the repair. At least I will be on a 6000ft runway so I can land straight ahead if it is really bad.

    I do have the bat wings. I know it is cable. The part that bent is the tubing where the cable terminates. That tip caught on the hangar wall while pulling the plane backwards into the unfamiliar hangar. I was not used to maneuvering in a V-shaped hangar and stopped as soon as contact was made but it bent that tube slightly up and in towards the fuselage causing slack in the cable in that bay along with the distortions in the fabric. If I were completely stripping both wings to recover I would convert to the straight aluminum trailing edge.

    That picture is a great help. It gives me an idea to try before I have to cut into the fabric. Thanks

    It is actually the cable trailing edge.

    Wingtip damage repair
    I unfortunately slightly bent a wingtip while pulling my Avid speedwing into my new hangar. I am looking for ideas about how to repair this and also if anyone has pictures of a speedwing wingtip that is uncovered so I can see what I will be looking at if I have to tear the covering off would be great.
    Thanks,
    Dan

    I figured out the problem. Apparently the fittings had been tightened a little before they were shipped to me from ACS. The ferrules in the nuts were already compressed to the point that the tubing would not go in far enough. I noticed this when I opened the 2 spares that I had and was able to push the tubing all the way through. I ordered new replacement nuts by themselves and they went together fine. I have hydraulic brakes on my Avid now and it holds better than the cable drum brakes did. Now it is time to tweak the geometry on the pedals to get more pressure.

    Nylaflow Poly-flow fittings problems
    I am finally close to finished with my brake conversion from the mechanical drum to matco disk. I bought new nylaflow tubing and poly-flow fittings from ACS. I tried tightening them up today but when I gave a quick tug test on the lines they all pulled out of the fittings pretty easy. I can't find any info on installation for these things to figure out what I am doing wrong? Has anyone else used these things that can pass along the trick to connecting them?
    Thanks,
    Dan

    Hi dholly,
    The pictures are a great help. I should have mentioned that I am using the Matco axles because I have an early C model which does not have any type of mounting plate for brakes at the end of the axle mounting tube. The Matco axles have a plate to mount the caliper bracket to and a plate for the inner bearing to seat against which is already set for perfect alignment of the caliper to my early W62 wheel/brake setup. I don't think I can move them in quite as close as yours due to the brake caliper plate mounting hardware but I may try to rotate my calipers down a bit and get them in as close as I can. I will try to get some pictures next time I am down at the airport.
    Oh yeah, I am not planning for skis, not much use around the Houston area
    Thanks,
    Dan

    Installing new axles
    I have had a few delays in my project mostly due to Hurricane Harvey recovery but I am finally ready to install my new axles in the gear legs of my Avid. I am using new Matco 3/4" axles as an upgrade from the old cable drum brakes to Matco disks. I am trying to determine where I should locate the calipers both in distance from the gear leg and also if there is a best clock position around the axles like ahead of the axle or behind the axle etc. I have marked what looks good to me on the axle for a cut off and the hole for the pin bolt to lock it in but though I should check before I actually commit to cutting the new axles.
    Thanks,
    Dan

    Went down to the airport and remeasured the axles. Not sure how I managed to measure incorrectly before but they are actually 3/4" axles. Felling much better about that now and my brake upgrade continues.

    Yes they are installed in a piece of tubing with the single bolt securing it. I expect them to be stuck in there pretty good after all these years but will manage to get them out somehow.
