Pre-judging a Tool

It is a rare thing for a tool to perform significantly different to what you imagined, and often that is not a positive thing.

So it is even rarer to find oneself completely surprised by how a tool just purchased operates, and in a good way!

The tool in question is the Arbortech Contour Sander.  It is fitted to an angle grinder and is for smoothing odd shaped items (such as one might create with some of the other Arbortech tools!)

Now the angle grinder is not exactly a tool that you would regard as being subtle.  It is loud, it vibrates, and it runs at around 10,000 RPM.  You would imagine that attaching a shaft to that, and sticking a piece of sandpaper on the end, that you are about to have some very rapid stock removal, in a cloud of dust.

Nothing could have been further removed from my expectation.

Instead, I had a tool running at very high speed (as angle grinders are want to do), but the sandpaper end was barely moving on the workpiece.  It is a random orbital sander style, so the rapid angular speed of the angle grinder translates into a more linear, but random amount of microstrokes.

It was subtle, it sanded quickly, but at a very controllable rate, and the soft end allowed the contours be sanded, without them being removed or abraded away.  Contour Sander indeed!

I think my only negative point was that the sandpaper is stuck on, rather than using velcro/hook & loop, so it isn’t easy to change from one pad to the next, working through the grades.

I’ve already used the sander on a few small jobs, smoothing and softening the natural edge of some timber, but I well expect it will prove a very useful tool for a range of projects in future.

  1. what about retrofitting it with self adhesive hook (like the one available for big disc sanders) so you can use standard hook and loop sandpaper… ??

  2. the hook and loop work well on flat surfaces the moment you introduce them to sharp curves,edges and odd shapes they wear out pretty quick as I have learnt using the festool ETS-Ec150/3sander

    • I was hoping it would still work, given both the Skilton and Ubeaut bowl sanders both use velcro. Be an interesting experiment 🙂

  3. Well… keep us posted 🙂
