Hi, today I fettled a tilting table that I bought quite a while ago but never have used. I have a little job for it, but there were one or two issues with it, First of all the top side of the feet that are used to bolt it down on the milling machine were not very parallel with the underside, which meant that the bolts were only touching under the head at one point, this I didn't like at all, because I thought that it would put undue stress on the T-slots and I couldn't feel that solid feeling of tightness one would expect. The worst one of the two was about 1mm taper from one side to the other and about 0.5mm from the inside to the outside. So after a bit of mind boggling, I decided to mount it in a vice on my milling machine with one of the feet uppermost and using a long series end mill, carefully mill the taper off.


I took several light cuts, as I did not want it to suddenly snag on any hard spots that may have been there and rip it out of the vice or even break it. As it happens it machined very sweetly. This next photo shows how badly it was tapered at the worst end from the right hand side to the left hand side.

The next issue were the shaped washers that nip the underside of the curve in the base section. Needles to say, they did not match the curve at all well.

The best I could do was to hold them in a hand vice and file them as best that I could for a decent fit to the curve.

Yes, the one unfiled really shows what an atrocious shape they were.
The final issue was that the table would not tilt either way to its maximum position, this was due to the bolts hitting the bottom inside corner of the slots, so using a carbide de-burrer in my battery drill to remove enough metal to allow the table to move just past the maximum mark both ways on all four corners and I just smoothed them off a bit with a small stone in my Dremel.

It now swings both ways nice and smooth and just past the last mark and bolts down to the table with a positive feel.
Regards Nick.
