I'm looking to build the "Simple, Sturdy Workbench" from Getting Started in Woodworking, Season 2 - http://www.startwoodworking.com/getting-started. The design attaches the bench top to the frame using s-clips, drilled to the bench top and slotted into the frame (with appropriately routed slots in the frame).
My question is: Is there any particular advantage for this method of attachment over using right angle brackets attached into both the bench top and the bench frame?
Unfortunately where I'm currently located, such s-clips may not be as easy to procure as right angle brackets. And I would have thought that right angle brackets would provide a more solid attachment given the multiple potential attachment points on both the bench top and frame. Also s-clips don't really aid in removing the bench top - if so desired - as one would still have to crawl underneath the workbench to unscrew the s-clip to remove the top. Or have I misunderstood something?
