I was using an inexpensive dust cyclone to filter the air coming out of the sandblast cabinet. The cyclone captured all the media and dust that escaped. I measured the efficiency of the cyclone at 98.6% for very fine dust. Its high efficiency worked very well to capture all the dust and blasting media before it reached the shop vacuum cleaner filter. Unfortunately, that meant it was not possible to reuse the blasting media because it generated a dust storm in the cabinet. KEE

The pool pump shaft seal on our neighborhood pool started leaking tons of water. Once we got the right size seals, it was a fairly easy repair. Watch the full video on how to fix the leaking Pentair Challenger pool pump: The pool pump housing is a Pentair Challenger mated to a large strainer basket. The pump motor we are using is a Century Centurion Model B1000 The motor shaft diameter is 5/8in Pentair Challenger Pool Pump seal kit Leslie's Pool Supply Repair Kit #65005 (Whic

One thing I despise about manufacturing is the amount of waste created. I try to consider and minimize waste at every step. MARKSMITH® PACKAGING Sealing The Packaging The Marksmith boxes must be sealed, especially for retail. Heat sealed and shrink wrap is a common way to do this. I don't like the additional plastic waste, so was searching for PLA or something biodegradable. Biolefin is a brand of polylefin shrink film that has adative (Revert) that allow it to break down fas

This is not one of those wimpy folding hands trucks. This is a seriously heavy-duty tool. I purchased my Wesco Aluminum Mega Mover here: https://amzn.to/37L3h0j 2026 UPDATE I have used this handtruck for 10 years, and it is still awesome. I do wish the tires were solid rubber. One tire has never held air very well. The other usually holds air for a long time, but I need to inflate them more often than I would like. The tire size is 8in diameter, 2.5in wide with a centered hu

Watch this how to video. Check the Dyson HEPA filter kit price: https://amzn.to/3jseZB3 My refurbished Dyson V7 cordless vacuum did not have the HEPA post-motor filter. I thought it was strange that it only came with the standard foam filter because it was the Absolute set, which is the nicest Dyson set. Fortunately, there is a third-party solution available that replaces the foam filter with a sealed adapter for the HEPA filter. The kit includes both the adapter and the filt

Watch the Youtube Video: Part 6 in my series on installing stainless cable deck railing on the cheap. In this video, I show how to install the stainless cable on stair railing. I break down the most difficult part of the whole cable railing installation due to the angled holes. I show how to measure the position for each cable and mark the holes for drilling. I also show how to use the drill angle guide to drill the holes at the right angle, and how to use an extra-long dril

Watch this video about how we moved the HAAS TM1 CNC Milling Machine using a rental box truck. The saga of this HAAS TM-1 CNC milling machine begins over 10 years ago when I first met my friend who's name I won't reveal, but happens to rhyme with Park MtChicken. At the time, he had crammed a HAAS TM-1 into a tiny little shop with such low clearance that the head raised above the drop ceiling tiles. Soon after I hired him to produce my first product, Scopemonkey Iphone Microsc

CAUTION! The first generation Gel Blaster SURGE has been recalled due to fire hazard. Please check with Gel Blaster about returning your blaster for replacement. The Gel Blaster SURGE is one of the few available gel blasters in the United States. https://amzn.to/372ingz Gel Blasters are still new in the US and haven't yet gained widespread popularity primarily because they are looked down upon by the airsoft community. However, I don't see these as a replacement or threat to

In 2017 I purchased two DIY LiFePO4 100Ah battery packs that were enclosed in ammo boxes. They have a cell balancer, but no BMS. I assumed that it would be ok to use them without a BMS because I had much more capacity than I needed, I have a 12V-12V Sterling brand charger to charge from the alternator and a Midnight Solar Kid solar charge controller setup for LiFePO4. What I did not take into account was the damage that could be caused by charging the batteries below freezing

I was first introduced to DLC Coating (Diamond-Like Carbon) by customers of our MARKSMITH Ti Bolt Action Marker when we were investigating different black coatings that could be applied to titanium. The coating needed to be the most durable available, so that it would not wear off. DLC claims to be one of the hardest, most wear-resistant coating that has a very low coefficient of friction. DLC coating is applied via the PVD process, so most services that offer PVD will also o
