I was thinking about a planetary gear transmission. Would it be slimmer? It would be like the one in the patent drawings, but with three planetary gears instead of one, plus an outer ring gear. Wouldn’t that be wider? The skinniest transmission I can think of is a bevel gear fixed to the handle, then two bevel gears engaged with it, and the shaft driven by the axle between those two gears ..read more

It’s a strange drawing for certain! I wonder if the drawing isn’t meant to be an example rather than a definitive design, even if you stuck the gears at the front why would you leave them exposed to dirt and debris instead of enclosing the design? Or make the whole assembly slimmer by using a planetary arrangement instead? Anyway, I hope someone has seen something like this out there because if well implemented it would be a useful tool–not just for difficult to drive screws, but also for making precise adjustments ..read more

Thank you sir! I appreciate it! That screwdriver design is a little puzzling. The transmission is at the front, and exposed to dirt and debris. I’d have put it inside the handle, to protect the gears ..read more

There is a patent for this exact thing but I’ve never seen one in the flesh or even a picture of one outside of the patent drawing. patents.google.com US5289743A - Two-speed reduction geared screwdriver - Google Patents A one-piece handle member provided with a bore and a tubular pinion gear fixed to and projecting from a forward end of the handle coaxially with the bore is rotatably mounted on the rearward portion of a single drive shaft against a driven gear... The closest thing that I have seen in person are reduction gearboxes that are really meant to be used with a drill. You could use on ..read more

The low flow rate is definitely nice for around-the-house sort of jobs. You mentioned using a 2-liter bottle on the Worx unit earlier–that sounds extremely handy. While searching for a 0 degree tip for the DCPW1000 I stumbled upon the fact that Dewalt offers a 2L adapter as an optional accessory for about $10. I will definitely be picking one of those up. Portability is the real strength out of this kind of machine. And I think the power is at a nice sweet spot as well: it cleans most things effectively but at the same time it is difficult to cause damage with it ..read more

I appreciate that you found less flow and power advantageous in some respects. The best most powerful isn’t always required and not always worth the increased price for the small percentage of time the additional power is required. I’d bet for that last little bit of oil stain a neighbor could be imposed upon for a quick use and every other job you completed without issue. Thanks for the thorough follow-up. I have an oil stain on my garage floor I may try with the worx and some simple green and compare the results with your notes/experience ..read more

Hello folks! My friend is looking for screwdrivers that are geared down, so that one rotation of the handle might mean a 1/4 rotation of the tip. There are a few screwdrivers geared the other way, for more speed, but this would be the opposite. Precision screwdrivers would be ideal, but any size would do. Anybody have any ideas ..read more

I’ve been doing more chores today and I had a chance to work the power cleaner pretty hard, washing two cars (a mid-size SUV and a coupe) a big Scag ZTR mower that was absolutely filthy, and one large parking space that was generally dirty, had oil stains, and had some algae/green sort of stuff on it as well. It worked great for washing the cars, it was nearly as fast as using a proper pressure washer. The foam cannon worked great, it was easy to spray down the vehicles with suds. It also surprised me just how effective it was at making foam without using much soap. If you filled up the entire ..read more

Congrats on the purchase and thanks for the detailed and well written review! I have the ‘Worx 720 psi washer’ for cleaning odds and ends around the yard and my car. I like the convenience of hooking up a 2 liter bottle for spraying down the patio chairs and table. That said it’s not going to clean much more than that whereas it seems the dewalt has some additional potential ..read more

After much anticipation I finally got my hands on the DCPW1000 power cleaner. This is basically an upgraded version of the earlier DCPW550. It is a handheld “mini pressure washer”, it runs on Flexvolt batteries, and is rated 1000 psi and 1.0 gpm. Here are my initial thoughts from the first things I’ve done with it. I bought the -B model, just the bare tool. It came with the washer itself, the spray wand, a turbo nozzle, three standard nozzles (15, 25, and 40 degrees), a QD adapter for the garden hose, a hose and filter assembly you can use to draw water from a bucket, lake, pool, etc, a should ..read more
