Building A 52 INCH Robot With Arm
Mounting The Rail To The Main Base
The wood used for the rail is call a furring strip. In Lowe's it would be listed as: 1" by 2" by 8' treated furring #201999. It is about 1 5/16" wide and about 9/16 thick. I used this type of wood because it seems to have the least amount of warp and bow. Cut a 48" long piece.
Cut a 1 1/2" thick piece a wood 3 3/16" by 3 3/16" You can cut a notch into the wood (see photo in step 5) to hold the rail in place and then drill a hole thru the rail and the block of wood. Use a drywall # 6 screw to hold the rail in place. If you do not want to make the notch in the wood block then you will have to use 2 more screws to both sides of the rail to hold it in place.
Place the block so that the rail is in the middle of the base and the block of wood is 1/2" from the front of the base. From the bottom side of the base use two drywall screws to hold the block of wood to the main base.
