Drill press samder, grinder... etc

I can remember when Bosch was Bosch. Not sure what they are today, but sure nowhere near the quality their power tools were 30 years ago. But if you needed a grinder heavy duty enough to run a 7" cup brush all day long you needed a 2400 watt 9" AEG 25 lbs of hang on tight or be whipped like a redheaded stepchild caught stealing pennies.
Metabo makes fine tools, and I freely admit that I have too much tendency to abuse angle grinders

I think its the size. Before for 125mm grinder 500w was maximum. Now you get 850w and 1000w grinders with very thin body. There simply ain't have room for decent airflow..

Should have thin machines for accurate use with low working time, and thicker ones for continous use. I happenen to forget that sometimes and then... "smoke"!

Here is couple pictures.
If you watched the video.. you might wonder why there was that plate stripe bolted to the casing?
Its for holding the rubber flap that keeps dust away from the bearing.


And here is where i use it mostly..



I can use my cutting fluid system for wet sanding too.
I had no suitable machine for this purpose before. Now i do.
Too high rpm ruins sanding pads and throws water everywhere..
Low rpm needs bigger torque, this gives it.

I can use this with rpm 50-600 with my drill press ( drill press spins 250-2700rpm). Its suitable for accurate and precise working. Imo.

I can definitely appreciate a low RPM disk, there have been times when I have used a 7" disk pad mounted in the chuck of my lathe for fine wet sanding. Obviously it is ludicrous to have a 3 or 5 HP lathe powering something that would normally mounted in a 350 to 600 watt variable speed drill motor but the lathe doesn't need to be held in a vice.
I do really like your set up and may build one of my own eventually or a variation there of

Great sheet metal work on that housing Tuomas! Very interesting concept and great that you salvaged the components.

Thanks for sharing another great build!!

Thanks buddy.

I did some wet sanding today, and it really seems to be usefull.
Also polishing plate edges steel and acryl is much easier now. Straight, shiny edges. I like. �� Also wire brushing is much better now. Bench grinder spins little too fast. I am very satisfied.
