Feb 14, 2023     Built some tables, moved some wings, got a box - (10 hours)       Category: Tools
Several things happened...

I sold my Cherokee, so I got room in my hangar to put the wings. To do that, I had to build more tables. Allison helped me with the build, which was really nice!

So, we loaded up a truck and hauled everything from the house to the hangar. I didn't take a lot of pictures, but the wing weren't too bad to move. They were just bulky. We also moved most of the empennage, the ailerons, the flaps, the wingtips, etc.

And, I got a big box from Sling in South Africa. More parts! Yay!!


 
Nov 07, 2022     Just a quick counterbalance - (1 hour)       Category: Tools
At some point, I am going to want to take the tail of the plane off of the big box it is resting on, and since I don't have an engine on the plane, the plane will probably tip back, hit the tail, and cause me lots of consternation. I saw on Facebook that someone else had put a pole on the front of their plane to hold weight plates, and I had some free time and extra plywood, so I decided to do the same. At the time I am writing this, I don't have any weights to put on the pole and I have no idea if it will be strong enough to hold the weights that I need, so there may be another entry later on that says this was a waste of $27 and an hour....

First I got some 3/8" bolt hardware because, well, it looked beefy enough. I had some 1/2" plywood laying around, so I cut it into a piece big enough for the front and some extra pieces to spread out the load from the washers and the pipe flange in the back. As it turns out, the engine mount frame is angled as it comes away from the mount holes, so the lower backing pieces of wood should have been smaller, or had notches cut in them, or something. I opted to just put the hole closer to the corner and it seems to work, but I would do it differently next time.

For the 1" pipe flange that is in the middle holding everything, I used large wood screws that were about an inch long. As you may recall, that is about twice the thickness of the plywood, so I put another piece of plywood on the back to increase the area that the load is on and to keep myself from scratching myself later on on screws sticking out.

When I get some weight plates (I'm looking at you, Craigslist and Nextdoor!), I'll get to see if this crazy idea works!


 
May 02, 2022     Right angle drill head       Category: Tools
I needed this right angle drill head to get into some areas that SHOULD have already had rivnuts, or at least been drilled to the correct size for Rivnuts...

Dec 27, 2021     Build the Sling wing slings - (5 hours)       Category: Tools
Since I couldn't leave the wings in the frames they came in, I built the EAA wing slings. It doesn't look like it would take a lot of screws but there are over 200 in there because of all the gussets. That being said, this thing is as sturdy as they come and the wheels make the system very nice. I was able to put the wings in with the space for the aileron and flap area exposed, which should make it easier to assemble once those parts are made.

Based on some pictures I saw on Facebook, I am going to try to hang the rudder and the vertical stabilizer (stabiliser?) inside the frame between the wings.


 
Sep 12, 2021     Shortening the Rivets - (1 hour)       Category: Tools
In order to rivet the bracket on to the elevator trim tab, I needed to shorten some of the 3.2mm x 8mm rivets to be about 3.2mm x 5.5mm. The instructions said that I needed to shorten ALL of the rivets that join the trim tab to the piano hinge, but luckily for me, there was plenty of space with the 8mm long rivets.

I used the dimpling press, with the dies taken out of it, to push the mandrel down and out of the rivet itself. I then turned the mandrel around and shoved it back into the rivet so the rivet didn't deform when I was cutting it. I cut the rivet with a hack saw (the mini-bolt cutter I was using deformed the rivet too much). One time, I cut through the rivet and mandrel and the other two times, I just kept rotating the rivet around the mandrel (I only did 3 rivets...so far). I don't know which way I like best, but it seemed easier to rotate the rivet. Once the rivet was cut, I pulled the mandrel out, slid it back in the right way, and tapped it back into place with a hammer. I put the head of the rivet down on a vise that was partially opened to allow the mandrel to slide through.

It didn't occur to me to get pictures until after the fact, but hopefully the description will help future me (or someone else). In any case, it seemed to work - the rivets still fit in the 3.2mm hole and they are holding tight to the bracket that the trim tab motor will eventually be pulling on.


 
Aug 02, 2021     Difference between Nitrile and Vinyl gloves - (0.2 hour)       Category: Tools
In case you were curious about the difference between Nitrile gloves and Vinyl gloves (and let's face it, who isn't?), it turns out that Nitrile resists Acetone pretty well. Vinyl, not so much. Good thing I didn't have any nail polish on, or it would have been gone!


 
Aug 01, 2021     Finally broke down and did it - (1 hour)       Category: Tools
I had been trying to just keep the rivets in bags. I was cutting, taping, untaping, and retaping the bags as I needed to get rivets and I was dropping some out of the bag when it wasn't taped well and having trouble opening the bag with gloves on (the clecos get my hands dirty, so I wear gloves). I have a set of drawers with a lot of empties, so I finally decided to just put the rivets in the drawers. Some sizes took more than one drawer. I should have done this at the beginning!


 
Apr 20, 2021     Needed new Rivet gun tips - (.5 hour)       Category: Tools
It turns out that the Proset XT2 I got only had 1 tip rather than the 3 different sizes. One of the potential problems of buying it from eBay, I suppose. In any case, I bought the other two tips from Blind Rivet Supply (blindrivetsupply.com) and now I am happily riveting away!


 
Feb 01, 2021     Catch all for tools - (4 hours) Category: Tools
I've been scouring eBay for Clecos and the ProsetXT2 rivet puller. I also got a regular hand-operate rivet puller and some other odds and ends. This entry is my best guess as to what all that has cost so far.
