« Part 30: Through Tenons & Table Top Layout Part 31 of Trestle Table series Part 32: Table Top's Bevels Cut with Circular Saw Cutting Jig »

I was preparing to cut the 30 degree bevel on the table top’s ends and the 45 degree bevels on the side on my table saw by using my tall rip fence jig.

Then I realized that holding the 60 inch length table top on its end was silly and dangerous. It would be very tipsy; hard to hold steady. Instead I will build a circular cutting jig for my Rigid circular saw. This meant a trip to my local large box store. After looking at the material options I decided to purchase a 4 ft by 8 ft sheet of 1/2” thick MDF. Since I was there to buy this sheet I also took the opportunity to buy three full sheets of 3/4 inch Birch plywood, 4 ft by 8 ft.

I have decided to build a roll around tool cabinet for my shop. This is a Woodsmith Shop Notes plan with a Shop Notes online library ownership I had purchased. I have a bunch of tools and power equipment that I want into a cabinet. Right now they are in the original boxes or tool cases they arrived in. Having them in a tool cabinet will make they more readily available for use. The tool cabinet will also be mobile in my garage woodshop.

Since I had to make a trip to the store, I did not complete the jig today. However, I did get the parts cut. I used a leftover 1 by 4 select pine 8 foot length piece for the fence. I jointed one edge flat and square to a wide surface. I then ripped the other edge square to the first. This will be the jig’s fence when completed.

I cut one of the jigs to 60 inches in length and that left the other jig to be 36 inches. From these two circular saw jigs I will be able to cut the bevels for this trestle table top and be safe doing it.

Tomorrow I will glue and screw these two jigs together. I will get the bevels cut tomorrow.

Instead of cutting the bevels on the circular saw jig on the short-side of the saw’s flat surface as shown in the photo above, I will flip the table over so the bottom surface will be up. Then I will be able to cut the bevel with the wide surface of the circular saw. It is probably the preferable method for cutting a sheet good with a circular saw; the show surface will be on the opposite side from the saw.

Robert, to proceed further cutting these bevels I had to build my circular saw cutting jigs. I am in the last stages of building those jigs now as can be seen in the photograph shown below.

Since the first use of these guides or jigs is for beveled cuts, I decided yo use only screws and not glue yet to fasten its fence to the MDF. This way after using the guides for this table top beveled cuts, I can remove the screws, move the fence a bit and then use glue and screws to fasten the fence permanantly for the more normal condition of making circular saw cuts with the blade set to 90 degrees or perpendicular to board being cut.
