I have been working away the last few days without taking any pic's. So now, as I found my camera again, there is a bit of progress to be shown.
First here is a picture of the frame of the cutter itself. I was just laying it out to see the size and make a few decisions! Again the size being dictated by the belt length.(by the way, if you click any of the pictures, a larger sized slideshow should come up, nice!)
You can see the first of the X axis' supported rails here. The other is the gantry rail temporarily. I cut the box section with the bandsaw and finished it with the flycutter on the lathe. I really like the fly cutter, it such a lovely finish. Great for butt joints.
Below is the linear bearing and belt setup for the gantry. The "belt through the hole" idea is from the LightObject design. A nice space saving idea.
It allows gubbins to be directly above the bearing and belt. The clamping plate setup is the same as the gantry. One fixed and one adjustable.
In the picture above you can see the bolt holes for the motor mount and the access for the linear bearing bolts. Mine is off to the side a bit, due to the fact the I had to bolt the bearing and spacer on from above.
Here is a wide of the gantry minus the rail, motor etc.
Just tonight I finished drilling the 8, 22mm holes in the bearing blocks for the X axis belts. Each hole took 8 different sized drill bits. Spotter, centering bit, 4mm, 7mm 11mm 13mm 16mm 20mm 22mm. It makes it time consuming but the way the hole is still in the right place at the end makes worth while. More on that in the next post.
