I built some simple add-on bench tops that attached to my small workspace lab bench which more than doubles my bench top surface area. The tops are easily removed if I need the space in my garage. The tops are cheap $18 finished project panels 3/4 in. x 2 ft. x 4 ft. pine birch from Home Depot (Store SKU # 958751). The standout legs are $6 finished 2 in. x 2 in. x 6 ft. radiata select board (Store SKU # 532157). The legs are attached with $3 leg attachment kits called Heavy Duty Top Plates (Store SKU # 779225). Everything else is just glue, screws and scrap 2×4 materials. Total cost with tax $68.
The 5-Shelf Wire Storage Unit was $70 at Home Depot “HDX 36 in. W x 16 in. L x 72 in. H” (Store SKU # 401454) and I got the wheels separate for $20 “HDX 4 in. Industrial Casters with Bumper (4-Pack)” (Store SKU # 563065).
I got the Bausch & Lomb stereo microscope with boom stand second hand for $100. I found the barlow “0.5 X CAT. NO. 31-26-18” lens on eBay for $36.
