X-Y Base Part IV

X-Y Base

Part III of this build could be found here. Had time to work today and was able to finish up the X-Y base by attaching an improvised vise where the workpiece can be held during milling. All that's left to do with this is attach it to the frame. But before that I have to finish up the Z axis platform of the grinder.

Another problem that cropped up in the X-Y base is that the entire base has a certain level of play between the drawer slide and the stage. I was thinking about slipping a piece of metal in between them to cut down this level of play to reasonable levels. Of course if I really had the moolah I would be buying an industrial grade X-Y table or at least building one using mono carriers. I remember inquiring about linear guides for my engineering thesis project and was blown away with the cost of it, who knows how much they cost now?, probably more than the arm and leg they were charging before *snicker* I could try ebay but with the weight of these things, shipping cost would most likely hit the roof.

Here's the arm where the mini grinder will be placed. I had to cut up a new piece of metal for the arm because during mock-up I found out that the original arm was too short.

Still figuring out how to secure the grinder to the angle bar end tip of the arm. The angle bar was attached by using rivets.
