Now for the interesting stuff. I’m not going into detail on the first table design because I feel that the second table design will be more stable. Again I am open to all criticism and advice, that is the only way we learn in life.
One very important fact that I would like to make clear is that the total travel (up and down) of the tables in both design will be 1/2” You will see that there is a vertical row of holes on the 4 legs, they are for 1” increment size changes with a maximum workpiece thickness of 4 3/8”. All that is need is to loosen 4 bolts. So I will be able to finish sand small boxes or other thicker jobs as well.
This works on a back hinge system.
This is the lifting table, it wil be secured to the frame using 4 bolts. The black knob at the front is attached to threaded rod and is for fine adjustment of the top table.
This is the top table and it will be secured to the frame with 2 bolts towards the back for a hinge effect. The front will rest on the lifting mechanism of the bottom table. Both sliding areas of the tables will be 3/4” plywood lined with 1/4” hardboard for smoothness.
Okay, that is it for design 1.
The biggest factor for design 2 was that I want the table to lift back and front together, I’m not very fond of the hinge type lifting. Not to sure why I feel this way, just like the table to stay horizontal.
I kept the main design for the lifting mechanism, just doubled it up.
The last pic is just to show the maximum intend height that I intend to lift the table. The rest of the setting will be done as explained at the top. 1” increment drops with the holes on the frame.
You will see that I have added 4 blocks to the top table, that had to happen otherwise the top table would be floating around on the 2 lifting parts which obviously is not a good idea. The 4 blocks will house 2 bearings each, one at the top and one the bottom. That is also why the frame changed, there will be 4 guide rods for the bearings so that the table can’t float. The only drawback to this for me is that I still cannot look at changing my table to a belt feed system. I’m working on that, “Design 3”. No success yet on that one.
Thanks for watching and the advice, I appreciate all criticism and advice.
