This is a new oscillating sander that I bought yesterday. The spindle not only revolves, it travels up and down in a linear motion. I have never had much luck getting smooth inside corners on my aluminum fabrication work for small engines. I have tried filing, wrapping sandpaper around a dowel, even sanding drums mounted in my milling machine, but non of it gave really great results. This machine comes with five different size arbors, from 1/4" up to and including 2" diameter. Hopefully, this is going to improve the quality of some of my work. It was on sale for $160 off the regular price, so I dug deep into the Rupnow fortune and bought it.---Brian

Hello Brian,
I do not own one of those sanders but I have used one of my friends and it does a beautiful job, you will enjoy it.
Have a great holiday,

Should help a lot - the vertical motion of the drum reduces the tendancy to get grooves in the work, dont have one but used one back in school shop many moons ago.

I have often wondered how those will work for modeling work Brian. Please keep us posted on the results.

Now You get to make an adapter to do square corners. :Lol:

Someone asked me to let them know how well this oscillating sander worked on model engine stuff. I tried it today for the first time, on the interior curve of what is going to be the base for a rocker arm support. It works great. It takes a bit of getting used to, but it does a fine job. I used my band-saw to remove the majority of the metal, but for the cleanup I used my new sander.---Brian

That is a very nice finish there Brian!!

Looks great! For outside and larger inside edges, looks like it could be a replacement for a die filer.

Brian,
That looks like quite a handy tool. I would consider it if I didn't have a die filer available.

Finally I took a break from working on my sideshaft engine and built a stand/cabinet for the oscillating sander which has been setting on the floor of my office ever since I bought it. Half a sheet of 3/4" plywood and half a days work. I had a heck of a time deciding where to put it. There is no more room in my tiny machine shop and it's fourty below out in the main garage. I discovered that bit of space between a rack of shelves that has filled up with toys and the door into my machine shop.
