However, after reading that last night, I decided to find out once and for all what the differences were...in detail....so I could redeem myself! I took the afternoon off work (it was a slow day anyway) and spent the afternoon in the shop, completely tearing down two columns, one PS and another MS, and took a boatload of pictures, made a LOT of measurements, etc., and am finally able to update my tutorial with detailed information on how to modify your existing MS column.
I just sat down to get started on the new PS tutorial add-on. It'll probably take me most of the evening to put this together, because of the vast amount of pictures I need to process, but this is going to be my project for this evening. Hopefully by the time I call it a night I'll have posted an update which will show you exactly what you'll need to do.
The only thing missing off this page will be the mods needed for using a 3-spd column. I do have one of those columns and will be updating the tutorial again in the very near future, as soon as I can sit down and tear it apart and compare it to the others.
Stay tuned!
