I saw that too, but I'm thinking the rating of the contacts is based on watts, then my 1800 watt system is well below their 11.2k watts (32vdc x 350A cont).

I want to add a battery disconnect switch for my 48v yard cart project, for 2 reasons . . . there is a small voltage drain from the motor controller that I'm concerned will eventually sap the batteries. I'm also concerned the motor controller could be damaged from connecting/disconnecting the...

I don't consider it "puttering about", but on the rare occasion where I find I've got time without a specific purpose, I do what I refer to as "The Pick-Up/Put-Down Game". (Side note, I'm a pack-rat and and am easily distracted, so my workshop is usually somewhat disorganized.) The game is...

My rule of thumb for pop-rivets has been to match the material being riveted to the material of the rivet, i.e, if I'm attaching aluminum to aluminum, use an aluminum rivet. In cases where I've needed to attach aluminum to steel, I'll use a stainless rivet. On a few projects where weather...

Way off the mark for what it's supposed to be used for, but I used a cordless Milwaukee hammer drill to create texture on copper. Mrs. Imagineer asked me to make a small concrete plant box*, and if possible, add a metal (copper) accent band. The 040" thick copper band looked too plain, so the...

If you can find it, this stuff works great: http://kleanstripauto.com/products/aircraft-paint-remover I got lucky and found an Autozone that had a few extra gallons left. You have to search for the stuff that does not state on the label, "NON-METHYLENE CHLORIDE" I needed something for...

In the late '70's, my cousin had a body shop in a sketchy part of Quincy, MA. For window bars, he used regular 3/4" black pipe, but slipped a length of solid 1/2" stainless rod, greased, in side each so if the thieves tried sawing the bars, the stainless rod inside would just spin.

Keeping with my motto that there are no simple projects . . . I've embarked on a new project - Making a 48vdc yard cart for Mrs. Imagineer to use in toting garden tools, dirt and water about our yard. The cart will use a transaxle from a Craftsman (MTD) lawn tractor. The used axle came with...

I have a slightly larger version of that type of wrench that's used for turning the spanner ring on motorcycle rear shocks.

A Ryobi detail sander. It was a gift from the in-laws. Best I can tell, it's supposed to just make noise, because it doesn't do anything else.

In my workshop, I have a homemade dust collector than can be tasked with exhausting vehicle fumes. The collector is made from 2 - 55 drums stacked, with an 2hp impeller fan on the top. The sawdust and chips are pulled in near the top of the upper drum and due to friction around the interior...

I made something similar for our old chihuahua mix. Even with carpet on the ramp, he couldn't get traction, so I added 1/2" thick x 1" wide battens under the carpet running across the width of the ramp, 6" on center for him to gain a foothold.

Nice idea. Maybe add some pipe insulation, or split pool noodles on the bottom to protect the kayak's noses?

https://www.amazon.com/dp/B08KDFQ4JT/?tag=atomicindus08-20 I should be embarrassed. For years I've been breaking down discarded electronics (copiers, battery chargers, etc.) to recover usable bits and pieces, and I keep a spreadsheet of things like IC chips, stepper motors and drives and...

I answered my own question, and will be incorporating a 48v to 12v regulator.

Question about pulling power from one battery in a matrix of 4 batteries. I’m building a battery powered yard cart for Mrs. Imagineer to use, primarily to tote water to the various planning beds scattered about our 2+ acres. The drive motor for the cart will be 48vdc and be powered off 4 -...

My father in law cracked their ceramic sink (drop in style) by pouring in a pot of boiling water (in an attempt to clear the pipes).

I just fixed it myself. Didn't bother with insurance or a police report. Luckily it was a silver '96 Town & Country so finding a used grill and silver bumper cover wasn't too difficult. The tow was free (AAA), parts were only about $700, the AC recharge was 4 or 5 of the DIY cans from...

I don't know if 'found' is the correct word, but I ended up with a free 4-way lug wrench in the grill of a '96 Chrysler minivan. Apparently it had just fallen off a truck heading east on the same road I was taking west. I never saw it coming. It just impaled the grill, radiator, AC...
