The slots on the Perfecto table were all different shapes, rough, unmachined, off center, and not symmetrically laid out
This caused problems with clamp bolts.
I don't like altering old things, but I finally decided to tidy up the slots using the mill.
The slots are not perfectly symmetrical, or central to the table, but they are close enough, and better than they were.
↓ Here is the state of the table before machining
I used a paper overlay to help realign the slots and make them more symmetrical
This is the best I have as I lost some of the original photos
↓ Here is the untouched underside, after the slots were machined.
I will tidy that up once I get the mill quill rigid.
We are always running the Asians down over the quality of their cheap machines (the cheap machines that we have demanded in the first place!). We can produce equally poor work in this country, as seen in this shaper table. You gets what you pay for.
Anyway, it was worth all the effort. I can put larger bolts in the slots now and not struggle to position them.
