Cheap and Quick Indexer

Post by Paul A »

I had a job earlier in the year to produce 6 x 2metre high ornate columns, I was in the process of building a stand alone indexer using Shopbot controls but with the volume of work I had and the looming completion date to coincide with the Olympics I had to make something quickly.

I had plan "B" to make one to fit on the end of my Shopbot PRSAlpha,
the framework was made from 18mm Birch plywood and some parts from an old turning lathe, the only bit I need to buy was the drive stepper to the chuck adaptor.

The Birch plywood was held together with hex bolts and cross dowels and finally bolted to the end of my Shopbot.

If you only have a hammer, everything looks like a nail.

Hi Paul
I like your design,
I also made my indexer using .500 Baltic Birch ply. I used a 1:4 belt drive setup, and I find that the stepper runs very hot compared to the ones that are mounted on .500 aluminum on the X,Y & Z axis.
I know wood does not transfer the heat, not sure just how hot it is getting, but you can not keep your hand on it. I was just suppose to be a mock - up before cutting into .500 aluminum.
Do you notice that your stepper motor runs hot?
