CNC Shark Forum

I want to share my experience upgrading my Shark Pro Plus table. The factory table was just too flimsy, especially when clamping down heavier pieces of hard woods
so I built a new one. This one is 1" thick extrusions each 2" wide. The extrusions are bolted down to a 5/8 x 3/4 aluminum bar that is bolted to the black composite chassis.
I used 30 bolts on each side. This table is a vast improvement from the original. It took way more time than I had planned and I had to work thru some issues so if anyone is interested
I will write a post of what materials I used and some of the pitfalls to avoid.

Looks good. I did mine with 8020 table top also.

Hello everyone. I have completed a document that describes in detail the methods and materials that I used to build the table posted in this topic.
Please see the attached.

FWTW, 8020 makes the same extrusion in 1x3 size. I used 10 pcs on my table for the 24x24 shark.

Since the factory tables can be out of alignment, I used aluminum angle with slotted holes to be able to adjust the corners up and down before a final tightening. Then put microadjuster bolts at the corners to hold the mounting bars in place while adjusting the table heights.

The 1 x 3 sections allow you to put 1x2 wood slats over the top as a sacrificial surface bolted down to the aluminum in several spots along the length, thus locking the adjacent aluminum extrusions together and also keeping the center channel in the aluminum open for clamping. The 1x2 can then be planed with the router to give you a coplanar surface. You can then use the router to put .25 inch holes for work locating pins in the slats. Pictured below.

Very clever Bob, your engineering skills are still shining.
