Step 1: Drawing Up the Plans
I used popular for the frame ( items 1-3 and 5) and maple for the table brace and roller blocks (items 4, 6 and 7)
I used a 2 x 4 trimmed to 2 degrees to allow the hinges to go over center.
The frame has dado's as shown.
The 1/4-20 Threaded inserts can be purchased anywhere.. Amazon sells them in packs of 25
To mount the 2x4 I replaced the number 10 and 8 screws with longer ones to go through the 2x4 and rear angle.
Step 2: Attaching Frame to Hinges
I used heavy duty hinges to assure the frame would be solid and could handle a load.
I purchased 7 rolling pins from Amazon for $5.90 ea.. They are now just over $6 dollars.
I removed the handles from the rolling pins as I wanted to use the 3/16 rod to attach to my 14 maple blocks. Note that there is a slot in the block for height adjustment on the frame.
I mounted one of the inner rollers to check fit and also help with height adjustment
Step 3: Attaching the Table Brace
I mounted a dog ear with a 1/4-20 threaded insert to this bracket as shown in the photo. I made a similar dog ear for the frame and again added a 1/4-20 insert.
The table brace is a bit of trial an error as the top and bottom need to be close to the same length. On the dog ear ends I bored a 1/2" hole through and put a 1/2 x 1/4 nylon bushing in both ends of the bottom brace and one end of the top brace. See photo examples of the threaded insert and nylon bushing installed.
The brace is designed to go over center thus when the table is in the closed position the middle of the brace is up and as you lift the table up it goes over center to hold the table level. I added an adjustment brace with a knob to allow me to adjust the table as needed.
Step 4: Closing Table Sequence
To fold the Table down in the closed position, you lift the table bringing the brace halves in line with one another then pressing with your foot to move it over center.. See photo sequence
Step 5: Opening Table Sequence
To open the table, just grab the lower section of the table and pull away from the saw lifting up and out until the brace is inline then goes over center and drops down. See photo sequence and video
Step 6: Finishing the Table
The 14 roller mounting brackets are all adjustable to raise and lower the rollers.
