Here’s a destructive teardown of an automotive in-tank turbine fuel pump, used on modern Petrol cars. These units sit in the tank fully immersed in the fuel, which also circulates through the motor inside for cooling. These pumps aren’t serviceable – they’re crimped shut on both ends. Luckily the steel
Things are coming along nicely with this year’s drydock operations. Shes looking much better, the second coat of bitumen blacking is on, we’re going to continue at a coat a day until we’re due back in the water. I’ve now removed the shaft from the stern tube to gain better

It’s that time again, so the boat is out of the water for it’s 3-yearly maintenance. Some things over the past few months have been bugging me, namely a pronounced vibration in the running gear while underway. (Issue was easy to spot here!). nb Tanya Louise being a very odd
Here’s a novel little gadget, a USB powered soldering iron. The heating tip on these is very small & might be useful for very small SMD work. Bigger joints not so much, as it’s only rated at 8W. (Still breaks the USB standard of 2.5W from a single port). These
In the process of going through the boat mechanically, ready for this year’s cruising season, some damage was discovered on the face of the main hydraulic propulsion pump that drives the propeller. Here’s the front face of the pump, with it’s drive shaft. The circular ridge isn’t supposed to be

As there was no other online example of someone converting a glow/nitro car engine onto CDI ignition, I thought I would document the highlights here. The engine is currently still running on glow fuel, but when the required fuel lines arrive I will be attempting the switch over to 2-Stroke
Here we have a Dremel MultiPro rotary tool, a main powered 125W 33,000RPM bit of kit. Here the field & controller assembly is removed from the casing. Here is the armature, which rotates at up to 33,000RPM. The brushes rise against the commutator on the left, next to the bearing,
