Yukon 48" Metal Workbench Height Extension Bracket

These height extension brackets raise the top shelf of the metal Yukon 48" workbench from Harbor Freight to have about 28.5" of space under the top light shelf.  I was redoing my printing setup and the workbench itself is sturdy but the original top shelf limited space for 3d printers (about 22.5 inches under the shelf).  With these brackets the H2 series now fits under the top shelf/light. 

 

All original workbench parts continue to be used with this design. This includes the original metal parts that surround the light fixture as well as light functionality.  These brackets simply move their install location up. 

• I also created brackets for the top of the shelf to turn it into a filament spool holder.  Brackets are designed to use 1/2" EMT.  They are linked here.  These spool storage brackets are designed to allow a spool holder run the length of the shelf or half of it if you wanted half spool storage and AMS or something else on the other side.  https://makerworld.com/en/models/2057952-spool-holder-brackets-yukon-48-workbench#profileId-2221628

 

To install you will need 20 additional nuts, bolts, and washers.  I used 1/4" machine bolts @ 1 ¼". I ran out so ignore the few oddball bolts in the photos.  

 

Installation:

I use PLA+ primarily but you may use whatever you like.  Adjust accordingly for shrinkage.

1. Install the brackets at the top of the beam (using your hardware) where the Yukon instructions show to install their metal brackets for the top shelf/light fixture.  
2. After you install the 3d printed brackets you revert back to following the Yukon instructions with the new mounting locations raised.
   1. Use your hardware for this as the original hardware is too shallow in most mount locations. 
   2. Be sure to install the hardware through the 3d printed brackets as well as the original metal shelf frame brackets.
   3. If you are wanting to install the spool holder brackets as well you can install them when you install the wood shelf on top. 
3. After completing the install, plate 3 has optional simple brackets made to connect the pegboard to the top shelf.  
   1. Install these with the leftover original hardware that came with the workbench. 

Note: If you are using an H2 with an AMS 2/AMS HT/AMS, I also designed some AMS 2 tilt stands as even with the brackets the AMS have lid issues with the top shelf.  With the tilt stands they are able to open as normal.  My P1S has a similar issue but I don't believe it would if it wasn't using a riser on top.  I will have a version for the original AMS uploaded soon.
