The blades that come on robotic lawnmowers like the Mammotion LUBA and YUKA are different from the large blades on a traditional gas mower. Robot lawnmowers use small, thin razor-style blades and rely on their sharpness for cutting because the decks have much less power than a gas mower. A traditional-style mower needs a sharp blade, too, but its sheer power can cut and mulch grass even when the blade is a little dull. A robot lawnmower needs a razor-sharp blade to keep cutti

There are many different designs for oil skimmers to remove way oil from coolant. Belt Tube Disc Most rely on the oil clinging to plastic or metal surfaces, while the coolant does not. The clinging oil is pulled up to a scraper, scraped off the belt (or tube, disc), and then runs down into a disposal container. The issue with these designs is that they also pick up a lot of coolant with the oil, as much as 50%, so a second oil separation unit is required to drain the excess c

The Danchee Ridgerock RC Crawler is a popular choice among RC off-road rock crawler enthusiasts for its rugged design and impressive performance at an entry-level price point. Yet, like many RC vehicles, it has room for improvement, especially in small but crucial components like body clips. These clips hold the body shell securely to the chassis, and upgrading them can significantly improve durability and convenience. Replacing the stock metal cotter pin clips with more dura

Our 5x6 mitering horizontal band saw stopped working due to a worn worm gear. The worm gear is made from softer materials (bronze or brass) than the worm (steel), therefore the worm gear will wear out first and is sacrificial. The specific model of band saw I have is a BS-128HDR METAL BAND SAW purchased in ~2012 from Northern Tool. It's a 5x6 cut size band saw, but seems to use the same gears as the less expensive, common 4x6 and 4.5x6 band saws like those sold at Harbor Fre

On the east coast, it's usually easy to find trees to hang your hammock. Sometimes the trees are not spaced apart correctly, or convenient for hammock hanging, or the park doesn't allow you to hang hammocks because it damages the trees when people use strings vs straps. In these cases, an alternative hammock hanging option is needed. The portable free standing hammock stands I've tried are too short, too low, heavy, or complex. I've successfully hung the hammock from the van

I would like a compact 3D printer that can fit in a small case to make it easy to transport. There are some compact DIY printer designs, but I want to use a reliable printer, not something experimental. The BAMBU A1 MINI has an extremely good reputation and could be a good candidate for making the Z axis fold to make it more compact. Removing the Z axis column of the BAMBU A1 MINI is not very convenient, but it looks it is possible to access the screws from underneath and by

I first started drying 3D printer filaments in the oven. Then I upgraded to a Print Dry unit that was basically a modified dehydrator. It was nice because you could dry and print from 2 spools simultaneously. This didn't solve keeping filament dry in storage. These are the least expensive, clear, airtight containers that can be used to store and dispense filament.

The DeWalt ToughSystem drawers are an awesome portable toolbox for quick tool access, but here are a few ways that they could be made even better. STACKING (How to remove the wobble) When stacked, the drawer tool boxes are not stable and wobble a lot. The taller the stack gets, the worse the wobble. There are cutouts in the lid for the feet to fit into, but the cutouts are so deep that the feet never bottom out. I found some designs available to 3D print, and some to buy. The

BAMBU LABS provides information on how to configure their 3D printers to connect to BAMBU STUDIO over LAN only instead of using the cloud. That way you don't have to send files over the cloud, and don't need to login. However, BAMBU STUDIO is still connecting to it's servers, checking for updates and showing files that can be printed, so it's possible that the files you load into the studio are not secure. After installing BAMBU STUDIO and setting up the 3D printer in LAN ONL

I'm documenting the build of the MASLOW 4 CNC Router and modifications that will make it even more awesome. SPINDLE UPGRADE The default spindle that the MASLOW 4 CNC was designed for is the DEWALT DW611, which is a popular trim router used in a lot of benchtop CNC routers. However it's not designed for extended use in CNC routers. It's designed for short term use hand routing trim on countertops, etc. It's a brushed motor, so the brushes will wear out and need to be replaced.
