    Congratulations Keith William Knull - your Sawhorses are the Homemade Tool of the Week!

    This was a very difficult week on which to win, especially with a fairly common tool such as a sawhorse. There was both a high volume of tools, and a large number of tools with many Thanks votes. However, upon reviewing the 85 sawhorses in our Homemade Sawhorses category, this one stood out because it appears to be either among the best, or simply the best design we've seen. Specifically: stability, collapsibility, and adjustability - both in regard to height and uneven terrain.

    Some nice picks from this week:

    Round Stock Vise by rossbotics

    Keith William Knull - we've added your tool entry to our All Homemade Tool of the Week winners post. And, you'll now notice the wrench-on-pedestal award in the awards showcase in your postbit, visible beneath your username:



    You'll be receiving a $25 online gift card, in your choice of Amazon, PayPal, or bitcoin. Please PM me your current email address and gift card choice and I'll get it sent over right away.

    A look through all of Keith William Knull's tools (viewable via the "Keith William Knull's Tools" link in his postbit) reveals that, like many of our tools, this one is likely the culmination of multiple similar builds. In fact I believe I see the folding ladder work table doing double duty in this build as a scaffold.

    Wonderfully clean, well thought out, function-driven design. And the heavy duty door hinges no doubt supply ease and precise operation, while contributing to the strength and stability of the overall design. Your photography is super, as well. I've never seen anything quite like it. Thanks for sharing.

    Mortise dimensions?

    The upper frame can be set on an angle to adjust for uneven terrain.
    What dimensions are your mortises if they are tight fitting, yet permit the top to be set to different angles as the terrain requires? I'm definitely going to build a set of these. Thanks!

    The mortises are tight fitting along the 3 1/2" faces of the 2x4 for lateral stability. The length of the mortise is approx. 4 inches, allowing 1/2" of play.

    Heavy Duty Adjustable Height Saw Horse-image2.jpg

    *design modification*

    After leaving the horses in the rain, the wood swelled which made the height adjustment really stiff.
    So, I just made a relief cut through the end of the 2x6 to loosen the fit and added a* through bolt and knob to tighten as needed to retain lateral stability after adjustment.

    I think if you're using these outdoors, this mod is definitely required.
