no previous part Part 1 of Wooden Toy Train series Part 2: 3D model of the train »

Making the boiler (or the round part that gives a steam train it’s distinctive look) was started in another blog, not part of this series, so at the risk of repeating myself, here goes:

Decided to make a cylinder “Cooper Style” (that’s what I call it) in the way that wooden barrels were made in the past. Cut six strips of pine with the edges planed down to 60 degrees (with a hand plane – no table saw here) to make a hexagonal cylinder shape.

Carve and hand plane it round, glued a wood disk on the end.

Carved and sanded to elliptical shape.

Because the boiler is hollow, very tempting to put a marble or a coin in to rattle around and drive the recipient crazy trying to figure out what’s in there. Sanity prevailed, and I came up with this idea: put a door of some kind on the cab side of the boiler. Knowing that in real steam trains, both the front and back are accessible. Putting a hinged opening on the front is basically out of the question for a simple toy like this.

Showing the fire door opening mechanism to get access to the inside of the boiler. This is a test to see how it will work, paint it first and let the paint dry properly otherwise it will be glued in place permanently.

Now the young protagonist is able to place precious objects inside the boiler.

Looking good Tony, just one question please from a bloke who doesn’t have a wood lathe… Is there an easy way to round the cylinder for the boiler???
Thank you…

Good news and bad news – there is a way, it’s simple, and “easy” is a relative term. Technology today has made everything “easy” – woodworking is now only a matter of passing the timber through a machine if that is what you choose to do.

The way I did it was to paste a pair of circular paper discs on each end and hand plane with a No. 2 finishing plane. Must admit this was the third attempt, the first two coming out the wrong size because of a failure to measure correctly.

The photo shows the hand with the hand plane in action. Note the paper disc with a hexagonal shape hole in it to allow clamping to the trusty workmate, and the orange colored bench stop courtesy B&D.

Bear in mind that the grain must lay in the same direction. It does take a bit of patience, and make a fair amount of wood shavings. Also tried paring away most of the waste with a chisel, but you have to be careful not to take away too much.

Another point worth mentioning crowie is that if you make any kind of a cylinder with staves, if the project calls for the inside to be rounded too, then each stave must be hollowed out before glue-up. This would require a hand plane with a rounded bottom or an easier method is to do it on the table saw. There are lots of Youtube videos on that subject under ‘cutting coves on a tablesaw’. The easy way to do it is to cove long lengths and then cut them into staves afterward

Thanks to Mike for the information about the staves. Incredible to think how much skill is involved in making wooden barrels. Wonder if anybody is still making them?
