Like this, perhaps? You could make it even spicier if you got some hydrogen peroxide as well...

Thanks Andy, I've got a 10" one. Never thought I'd say that line. I found online an old newspaper advertisement where it's advertised with a 3/4hp motor. The associated web page tells me that a 1 1/2hp motor was an option as well. I've decided to go with a 1 1/2hp 3 phase and run it through a...

Today I found a spare hour and spent it finishing the flywheel turning. All it needed was one chamfer on the rim and the centre reaming so that went quickly. Then I decided to bore the cylinder. It's not obvious where the centre line is relative to the outside but there are two surfaces which...

Luckily, our excellent government have found a way to grow hydrogen on trees so that it doesn't need to be made from natural gas, but there is another factor that needs to be considered. The density of liquid hydrogen is very low, so if your motorcycle has a 2 gallon / 10 litre fuel tank, you'll...

Well yesterday turned out to be a long day, dragged out of bed by a work phone call and didn't get back until eating time, so I didn't get anything productive done except paying the bills. I was watching a young man by the name of Keith Appleton, who has been known to mess with this kind of...

One problem that you will face is that the lighter fractions will evaporate off the WMO leaving the heavier more tarry bits. The exact composition of the fuel is very much unknown and you need to proceed with caution. You risk ending up with a whole lot more fuel in your vapouriser than you...

I'll get some this morning. Thank you.

Today's playing has been with the flywheel. I stuck it in the 3 jaw to start, facing the boss. then that got centre drilled and a live centre backed it all up to hold it securely. The OD wouldn't get a good finish and at first I put it down to not being through the skin yet. It turned out that...

Yesterday's progress was a bit less than I'd expected but the casting has more fiddly bits than it appears from a quick glance. After I'd got the casting "fastened" to the jig plate I used my edge finder to determine half way between the crosshead slideways for my Y zero and half way between the...

The start can be found here:- https://www.homemodelenginemachinist.com/threads/stuart-s50-my-first-engine-build.36094/ I thought that that place was where it was best but it has been kindly pointed out to me that comments etc can't be posted so I'll never know how much of a mess I'm making of...

The 1-2-3 block idea is thanks to JasonB who suggested it in my angle plate build post, thanks Jason for the great idea.

Thank you, this will be on my wall tomorrow morning. I'll need it for my Stuart build translations and when I'm not there I'm sure the mouse will like to look at it.

Starting at the bottom, making something that the other finished bits can be mounted on appeared to be a theme on the YouTube community so that seemed a reasonable place to start. The first thing that struck me is that there are no starting points for the dimensions, all are referenced to an...

After a lot of prevaricating I bit the bullet and bought a set of castings. Obviously the cheapest, simplest one I could find and its been on my dining table for a while now. I've looked over the bits and the drawing and pondered which bit to start with, if I should do the easy looking bits...

New problem / issue. The stopgap motor that I fitted all those years ago is rated at 600W. Must have been the biggest Machine Mart had on the shelf, maybe I got it just to see if it turns, who knows after all this time. Now I'm wondering how big a motor do I need? 1.5kW? 5.5kW? More research...
