holding part in place for screwing

How would you hold a long piece butted against a face precisely in place. for screwing. I working on building thickness sander based on Scott Markwood's video and want to screw two 2" x 19 1/4" x 3/4" plywood stretchers in place exactly 1/2" from bottom and 1 1/2" from front edges of the side pieces.

One piece is attached at the front to left and right sides. Then another at the back also to left and right sides. That means there are four attachment points, all using the same position measurements.

Two top 3" tall stretchers also will be screwed in place but flush with top edge of side and 3/1" from front and back edges respectively.

I was thinking of making a jig that would clamp in place. But I'm probably making it more complicated than necessary.

thanks,

Two spacers. One 1 1/2" wide and the other one 1/2" wide. Use double stick tape to secure them in place and install the screws. Then reuse them for the other joints.

I would cut a spacer and clamp it on where required. Maybe four of them.

Hey John and Dusty,

Both of those seem like great ideas. Much thanks.

I would locate and drill the holes in both the side and the connector. then align the holes and insert screws.

More persnickety process.

Sorry I am catching up reading posts from earlier this month.

Thanks! Makes the most sense to drill it that way!
