How nice to see you here (again?)! Updates? Every Thursday.
Have a look around, have fun and please post a comment, if you see something you like or if you’ve got a question.

If you’ve come here for the first time, continue this post to get a quick overview about me and my web site.

The motor is mounted.

Joyrider: Fitting the Engine

By assembling the tailplane the construction is finally finished, so now it’s out-fitting the model. As a matter of fact that’s already started since I fitted the aileron servos while building the upper wing.

I’m going to work my way through the fuselage from nose to tail. So today’s topic is set: the engine has to be fitted.

Sled bottom is being cut.

Workshop: Fences for the Cross Cut Sled

The easy part was constructing the sled bottom. Now it’s getting straight at the nitty-gritties, namely construction the fences and attaching them.

The front fence needs to be as level as possible, so it can’t just be cut from a single piece of board. Almost any board has some kind of warp which is simply inacceptable for a precise fence. Thus, the front fence has to be comprised of a cornered construction that is self-centering.

The runners' glue is curing.

Workshop: Cross Cut Sled for the Miniature Table Saw

As I mentioned in the construction report, I made a mistake while building the vertical stabilizer for my biplane, namely not chafing the trailing edge. Attempting to correct this using the transverse stop thoroughly failed. In order not to have to repeat this experience, I’m building a cross cut sled for the circular table saw.

However, a cross cut sled is capable of many more things. For once it facilitates to repeatively cut slats to length, thus one can skimp on a mitre saw. And then one can use it to get small boards back to right angles which were cut crookedly, so they can be rip cut again. So today is about the first part of a mini project which will facilitate my other handicraft.

Construction is finished.

Joyrider: Tailplane Assembly

Finishing the vertical stabilizer only leaves the tailplane’s assembly. Here, three important objectives have to be met: the horizontal stabilizer must be in parallel to the long axis, so must the vertical stabilizer, and the vertical stabilizer has to be at right angles to the horizontal stabilizer.

The most important contribution to the right angles is provided by clean, perpendicular cuts, which I can achieve easily thanks to my table saw. In order to further stabilize this orientation, I’ve constructed two guides from balsa wood and sanded them into a streamlined shape.

The vertical stabilizer's guide is in progress.

The structural work is coming to and end: since the horizontal stabilizer has made much progress, it’s the vertical stabilizer’s turn.

I rectify this by reinforcing the corners with small wedges of balsa wood. And this enlightment directly flows into the vertical stabilizer.

Joyrider: Horizontal Stabilizer

The landing gear’s completion left only one step to finish the structural work: the tailplane. I copped out for a while to face this step because the tail plane ultimately makes or breaks the aircrafts stearability:

If it’s too small, you can’t control the model aircraft. If it’s too big, the bird responds like a proper boulder. This effect is additionally influenced by the fuselage’s length, as I’ve already mentioned while building the fuselage. That’s why I’m really glad to have found Christian Forrer’s web site, including an excel sheet for calculating model dimensions, before I started constructing my biplane in earnest. Based on the finished parts, I was able to determine the minimum size for the tail plane and get on with it.

Winter Operation Session 2020

Last Saturday, an old friend of mine and I held a small operation session at his place. The weather was fabulous, we had high temperatures for february, around 14°C and lots of sunshine.

It’s been a huge success: multiple trains running simultaneously, shunting, test drives, lots of talk on lots of topics. But most important: a train-load of fun!

Shunting Dice for Operating Sessions

The operation session which a good friend of mine and I are planning is approaching. It’s going to be a premiere in more than one aspect: we haven’t done joint operations for a long time; it’s also been a long time since we did some shunting; and we’re going to try and let children participate.

So the question stands: How can we combine interesting operations with as few rules as possible and as little preparations as possible? Enter *drumroll* the shunting dice.

Loaded and secured.

Timber Cargo for Stake Waggon

In preparation for the next driving session at a friend’s of mine, I focused on Stake Waggon #101. (By default, which other waggons do I possess right now?)

The little darling is supposed to serve as a coupling adapter (knuckle coupling at the front, LGB’s “bottle opener” at the rear). So that it can excel in the task, the waggon needs some additional weight, which I provided by means of a timber load. And in order to keep the latter in place, some fastening had to be added.

Threaded rods are screwed into the wood.

Porter and Tender: Coupling-Maintenance

My faithful Porter had some work to do during this winter, for which it was transported to different places: Into the garden, at my parents-in-law’s, even at work. Of course, these transports always entail boxing and unboxing into transport crates, which lead to considerable wear regarding the coupling between loco and tender on the one hand, and the conductor’s platform at the tender’s rear end on the other hand. Thus, we’re going to focus today on ever-occuring maintenance and possible improvements.
