I hadn't thought about that!

My uncle brought a cottage and the garden shed was next to a stream. It had one light bulb in it driven from a water turbine; a couple of years later the waterboard were doing a survey in the area and made him take it out.

Have you thought about having a gear on the shaft instead of the slot and it is driven by a gear on the motor/gearbox? You could have two microswitches at each end of the travel to reset with some hard stops. I would think this would be more efficient than the slot.

I didn't know you could get Li-ion AA size batteries and it would be interesting to see if they are 1.5V as advertised or actually 1.2V. Reading one review they were 1.5V but not as powerful as stated. Li-ion shouldn't/can't be charged below freezing. I had a multi charger years ago and tried...

I had problems with a smeg oven and it was wired to a unswitched fused face plate. I removed the fuse but still received a shock. So double check there is no power before touching anything. Kitchen fitter wired the wrong wire to the fuse?

A guy I used to work with years ago was working on a bridge. One guy fell off and died and after that they were all told to wear hard hats :unsure:

I have used the Garryflex abrasive blocks in the past.

I have done it a few times myself; mostly with foam backed. I have done a couple of carpets without foam backing and you need a stretching tool to get a good finish and get it tight on the gripper strip.

If you want a sharp corner and only have a radiused tool you can dig the tool in at the shoulder to produce an undercut. A chamfer on the tip works just as well as a radius and is easier to produce.

When I was an apprentice most of the tools were HSS and hand ground. As you say not that hard to grind and once the original shaping is done it does not take long to maintain them. Getting the top rake and clearances correct helps.

We used to use a high top rake PVD coated tip for aluminium on our CNC lathes and it worked great for stainless. Found out by accident as the user once forgot to change it when changing over from an aluminium job to a stainless one.

Probably want to clear your cache. Trouble is you loose all your cache items which include saved passwords. Alternately you could try clearing your DNS cache.

I would say it is pulling too much power and so starving the rest of the house. I had a similar problem with a milling machine or arc welder; I can't remember which now. It may require an upgrade to the incoming electrical supply unless you and the wife are happy with the lights dimming...

Have you tried searching for control knobs? Alternative ideas if you can't find one or a temporary fix until you do. Get somebody to 3D print you one Buy one with an 8mm bore, on the face cut a slot across the side of the bore for a piece of flat material to be inserted to create the flat Buy...

In ours one apprentice set his arm on fire.
