Shopsmith Forums

First a little on status:
- Everything is built and on the planer
- Initial tests are done
- Calibration is proceeding
- Documentation will be wrapped up within roughly a week

I'm going to speed up the documentation a bit since the calibration is not going like I hoped. I wanted to tie wood types to specific settings but that isn't going as I would have liked. (There are more variables to be considered. If you are interested then see my post on the wood hardness chart.)

I also need to validate speed setting with the original Shopsmith configuration. That's where I need your help since I don't have a stock ProPlaner to use.

If several people could run the following test a report back it would help. The more data points the better to help eliminate variations in planers and the timing done.

Here's what I would like you to do:
1) Unplug the main planer motor so there is no drag to affect the measurements
2) Take the longest board you have and run it through the planer on both the high and low speed settings. Time as accurately as you can how long it takes to run the board through the planer in seconds.
3) Divide the length in feet of the board by the number of seconds to get feet per seconds (FPS) at both settings.

Respond to this post with your findings - FPS at both speeds and length of the board are needed. It will be interesting to see what the results are!

Thanks,
Mark

Following are the results of my Feed Rate Check. I hope this helps.

Note: I performed three tests at each of the three speeds (Slow(1), Mid Range(5), Fast(10)) to validate results. The Mid Range Test was performed to determine if the speed dial was linear. It does not appear to be.

I typically run at a speed setting of 4 and hardly ever change.
