When it comes to hot glue guns one thought is that it works or doesn’t work. And that’s true. But there’s more to it. I just bought this Gorilla Gun to replace the Aldi’s Workzone one that began leaking hot glue. First impression is very positive. Here is what I look for. When I squeeze the trigger I would like a smooth, predictable flow of glue. Not all hot glue guns do that. Even pressure and amount of glue corresponding to how much the trigger is squeezed. So far this one is really good in that regard. Now it is a mini model, not full size. I paid about $12 for the gun on AMAZON and it includes 75 mini hot glue sticks! Good deal. So if you are shopping for a mini hot glue gun, check out the Gorilla Hot Glue Gun.
At one point last year I actually thought that I would have the Duck finished for the January 2020 club meeting. It’s called optimism. I decided to build a box for the elevator and rudder servos. And I made it from Depron. One of the things that I learned taking existing plans and enlarging them 200%, and then doubling the thickness of the foam; that is probably not enough. I needed to add some doublers inside the fuselage and BBQ skewers to the stabilizers. They were just too flimsy. So you live and learn. I couldn’t just glue the servos to the 6mm fuselage rear deck. Just too flimsy. The Duck designer is a German fellow named Thomas Buchwald. That’s why the notes on the plan are in German.
Hard to believe that I have been using the WorkZone (Aldi) glue gun since October 2018, Check out my first post on it HERE. I have several hot glue guns in both mini and standard sizes and switch between them. I was working on a Depron servo box for my Jupiter Duck and suddenly noticed hot glue on my index finger, right hand. Sure enough there was glue leaking out. This was after it was sitting unused for several minutes. Maybe 20. So my advice with the Aldi gun is don’t let it sit unused for maybe 20 minutes. Use it, then turn it off until you need it again.
Still working on the Jupiter Duck. There are some areas of the construction where there are 2 or more layers of foam board. So it’s an old balsa builder technique; building on a building board. Normal balsa building pins are not long enough. Could bea building board of balsa, or a ceiling tile, or foam board. I came across these corsage pins on Amazon. Click HERE to visit the page.
This will be not news to the woodworkers and cabinet makers out there. You can use Forstner Bits when you want to drill a really clean hole in wood. The pic on the left below shows the BACK side of plywood that I drilled holes through. At least with me when drilling plywood I often end up with breakout on the back side; splinters of wood sticking out. Not so using these bits. The bit in the left pic is 1/4″. The other pic has a much larger bit for the purposes of illustration. The bits are available at Menard’s and Home Depot.
This is the Stanley FatMax Utility Knife model 10-481. Up until now I have been using the inexpensive, throw away, plastic knives. The ones I have use 2 buttons; one to lock the blade in position, the other to slide the blade in and out. FatMax has just one button that does both functions. And it has some weight to it. It feels substantial. Spare blades are stored inside. It just seems all around more comfortable to use.
I have been having some luck cutting the Depron foam with a hot wire instead of utility knives or xactos. So I made a poster board template from the plans, then used balsa building pins to hold the template to the Depron. I cut both fuselage sides at the same time. Seemed to work pretty good except when I pushed the foam too fast and not straight, the wire got under the template a bit so that it wasn’t really a square cut. Next time I think that I’ll cut one side at a time.
Now I just need the middle.
After I glued the horizontal & vertical stabilizers together I realized that it was a flimsy arrangement. The vertical stab is nearly 12″ tall with no other means of support other than the glue joint. I saw a few YouTube videos of other 200% Jupiter Ducks that had struts on both the tail surfaces and wing tips. So i came up with this way of adding struts to the tail. Used coffee stirrers and BBQ skewers. The large black triangles pictured hold the vertical stab at right angles to the horizontal stab while the glue dries. How did it work? Way better!
Two Krylon products came in handy for painting the tail feathers of the Jupiter Duck. Easy Tack allows you to make a painting mask, use it, the remove it easily. You don’t want to make a permanent bond. Then for painting I used another Krylon product called Short Cuts paint. Seemed to work well on Depron. I used white craft paper for the mask. And when drawing the mask I just moved the poster board templates around and traced it again.
