Bought a new machine yesterday---
« on: December 18, 2018, 02:26:19 PM »
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,
Thomas

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.

 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

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.
