| As I said, bad things tend to happen in triples.
So I hope the swivelling table will be the last component with this T-slot problem. And on this one, there were, of course, three slots needing attention: One in the base, and two in the middle bit. Well, mind you, the ones in the top plate were still perfect, so how should I complain? With the ones in the base I made the whole profile a bit wider. |
|
| A dentist's mirror is a very useful tool to check if the surface is already cleaned up! |
|
| Of course, I made very substantial T-nuts, again from 42MnCr4 steel. |  |
| Just compare the size of the contact area of the original T-bolt and the
new nuts.
As I said before, I would now consider making such nuts even for a new table, it saves so much trouble! |
|
| The middle section was a bit awkward to accommodate on my little FP1,
and I had to make a special tool holder for the T-slot cutter to be able to
machine the end of the slot next to the plate on the l.h.s. In the middle, you can see the damage; this was the worst spot. But even this one cleaned up nicely when I enlarged the whole T-profile from 10 to 14 mm. |
|
| And again, big T-nuts instead of the small-headed bolts.
I hope this will settle the argument! |
