Greetings from rainy Brooklyn, folks.
It is miserable and annoying but...at home, it is cozy and warm.
Today will be a short update from a previous post. Well..., I thought, I have finished with the cannons assembly overview, as declared quality 'out of the box' is dissent for the most part, but...something bothered me as incomplete and I thought about ways for improvement. So... here you go - Jim's way to improve the overall canon appearance.
I recall Triden Model told us that kit provided a solid base, and there are many ways for improvement. So I decided to improve the kit's cannons. One of the improvements made is in the canon trucks. Kit provided trucks as laser-cut, and the axletree hole was not round and perfectly centered. Obviously, you can make it round but this will require more sanding, and as the result, the trucks will be smaller than the required size. The second issue is the timber itself, it doesn't look good under oil, The material is very porous and soaks the oil like a sponge.
Original trucks were made from multiple timber pieces laminated and bolted together. Take a look at the images below.
The timber selection was easy, I cut the strips out of Pear and Castello just to see what would look better. Strips were glued together on the glass to make it perfectly flat and even.
Note two types of clamps: the metal clamps holding two strips together while glue sets, the plastic ones (blue color) holding the stips flat. The strips are only 1.5mm thick. Once the glue dry, using the tablesaw cut the strip assembly into the squares.
Now we will glue both squares together. Just make sure it is perfectly square (this is a 'must' for drilling the holes in the jig). Also watch out the line direction: both squares must form the 'plus + sign' e.g. on one side the line should be vertical, on another side it should be horizontal. I use machinist square to control the squareness
To make sure the glue evenly spread, I used the vise.
Time to drill the holes for bolt imitation. When repetition of similar work is involved, I always looking for jigs. A very simple jig was made to drill the holes, but this one ensures the holes were made on equal distance (assuming you have a perfect square). First, we will drill the axletree hole, because the diameter is the same for both hind fore axletrees.
Take a look at the above photo. There are two types of blanks: some of them for fore tracks, they will be larger than a hind truck, therefore the bolting pattern different. The next step in sequence - to make bolts. This time, I use brass wire 4.00mm, just insert the wire and cut flush on both sides. Time to make the wheels round. I use the wood lathe and turning chisel.
...and here are the trucks! They look perfectly round (actually they are)
The bolting pattern is equally distributed on the track. I am happy with the result.
The next part for upgrade is the
Stool Bed. It was made out of Pear with matching colors. First, both groves were made using the mill and round bur.
Below is the new (in the middle) and provided with the kit
This time I decided to use the carriage provided with the kit. Each bracket (left and right) was made in the upper and lower half. Besides the trucks, a major improvement was made on
Ironwork.
The cap-square, already described, held the trunnions in place. The bolts which held the cup-square in position passed through both parts of the bracket, and also help to hold the fore axle in position. I use the kit-provided cap-squares, and the casting beautifully represents both bolts. Another bolt passed horizontally through the transom binding the brackets together. Here I made some bolts. This required to use of washers which I don't have
...so I made one!
First, we will make some rings, the internal diameter must be a bit bigger than required. Using the jewelers saw we cut individual rings. The wire must be annealed to be very soft. Using the flat pliers close both ends to get a solid ring without gaps.
The next step is to flatten rings by topping each ring with the hummer until you have the desired thickness
You may use them as is but, should you decide to make them more uniform and more presentable, you can solder the gap like in the photo below
To be continued tomorrow...thank you!
