Yeah, a drill press or table saw is a few hundred pounds, a small lathe 700-1,000, and a knee mill over 2,000 lbs. We used an electric-powered stair-climbing dolly to put a safe in the basement. We bought it to deliver 350 lb 3D printers. Before that we used a furniture dolly and a block and...

Photopolymers tend to be brittle, have poor creep resistance, and warp over time (because the resin continues to cure). The process can also be messy. You can produce small details, and many of the machines can produce a honeycomb structure suitable for casting patterns. YMMV.

Mostly buy their tools to use onboard motorcycles. They tend to be light and compact because so many cyclists are “weight weenies.”

Rebuilt an old boat trailer that was unique to the boat. Including sand blasting the whole damned thing. A buddy had the setup, I supplied the labor. It was awful. Then you have to repaint it, redo bearings and seals etc. When I rebuilt my HF trailer I wire brushed the rust, sprayed it with...

Worked on several projects for those kind of parts. It’s been a huge waste of time. Their break-even would be as few as six parts, but they would have to pay the development cost. My scanner cost $25,000, the software $10,000, and though retired I’m not going to do someone else’s project for...

It’s probably 15-20 feet.

We have one of these in our shed. Says security light but we point it into the shed. Comes on when we walk in or I flip the switch. https://www.harborfreight.com/60-led-solar-security-light-69643.html

Bought some digital calipers 10-20 years ago. Now we have one that will also do fractional inches. Touch a button and it switches units. They’re like $25. Just bought a Starrett tape measure marked in CM and MM as well. It takes about five minutes in a modern CAD system to add a second drawing...

I disagree: my kids were taught techniques I regularly used as an engineer. I didn’t take Calculus until a couple years of college. My kids have or will graduate HS having taken it. And computer science and graphics as well.

Note to self: next time get a nail gun.... Hardest part of the job was pulling the old nails. They are SS deck nails so I reused them. Used a nail for spacing. Worked out just about perfectly, with a little extra gap under where water drips off the roof. Thinking about putting a gutter on it...

My business included selling solid modeling software to manufacturers for product design. With rare exceptions, all new consumer products, medical products, and most manufacturing equipment was designed in Metric.

From an actual owner..... Mercury and Yamaha each have the biggest chunks of the world market, with everyone else dividing up the remainder. From Brunswick’s 2019 annual report. https://ir.brunswick.com/static-files/ed97ec34-e44a-4b9b-ba22-5ac531766cc4 Thats $3 billion. Yamaha...

In our [2006 118” standard roof] van we used Thinsulate. While other products have higher ar values, the Thinsulate is much faster and easier to install, meets vehicle flame, smoke and toxicity requirements, and is easy to stuff into every nook and cranny. Used closed cell rubber foam under...

https://en.wikipedia.org/wiki/Ford_SHO_V8_engine “Ford manufactured the aluminum engine blocks, using a patented Cosworth process, at their Windsor, Ontario plant, then shipped them to Japan for finishing by Yamaha. ”

Don’t think 18V Li Ion weigh any more than 20V Li Ion. Because the ONLY difference is the packaging. With three Li Ion and three NiCad 18V packs, not going to replace tools that perform identically with the 20V packs just because DeWalt is practicing planned obsolescence. Especially when I can...

Yamaha made the engine for the original Ford Taurus SHO. Ford cast the blocks and shipped them to Japan for completion.

I love it, bought recipe saw, circ saw etc for pennies on the dollar. New OEM and aftermarket 18V Li-Ion and NiCads are available.

FYI these trailers have 25mm bearings. They look like 1” but they are not. The bearings, seals and caps are hard to find at auto parts stores. I ordered online. Mine was the 1750 non folding, no longer sold.

We have a 14.4V drill and light. Bought some clone Ni-Cad replacements for $18 on eBay that work well. Sticking with the 18V as you can still buy new Li and Ni-Cad replacements and the 20V has no performance advantage.

We have 18V drills, circular saw, reciprocating saw, and impact gun. Just bought the circ for $70. We don’t use the “20V” adapter because it’s also 18V, in a different form factor. We have two Li batteries, two factory 18’s, and several aftermarket. Aftermarkets are like $33. They work...
