	10. Hole-y smokes it’s boring! Making holes in metal	06 nov. 2026	01:11:11
This week we’re talking about making holes in metal— twist bits, step bits, annular cutters, hole saws, mag drills, and plasma cutting for steel, plus the tips and techniques for smooth cutting. In this episode: Choosing twist drill bits in mild steel, including how to avoid binding or snapping bits Differences between high-speed steel, cobalt, and coated bits and which we prefer for shop vs. job-site work Using cutting fluid (oil-based vs. water-based) How step bits work for enlarging holes and deburring, including practical thickness limits Using annular cutters (and mag drills) for larger-diameter holes Hole saws for thin sheet and larger openings, including limitations on precision and thickness Thermal methods (plasma, laser, oxyacetylene) for cutting holes when drilling isn’t practical Basic layout, punching, and other ways to keep bits from walking Alternative approaches for oversized holes (angle grinder, chain drilling, dies, and traditional blacksmithing methods like punching or slitting and drifting) Practical notes on drill speeds/feeds and reading chip color as a temperature indicator Listener question on how to get started with alternative fuels for engines _______________________________ Welcome to the Greenhill Forge Podcast, with Eric from the Greenhill Forge YouTube channel, and my buddy Amal, a fellow builder of many trades.

	8. Absorption refrigerator: cooling with fire, water, and salt	23 oct. 2026	01:02:16
This week we’re talking about Eric’s recent video on his absorption refrigerator design that uses water as the refrigerant and calcium chloride (road salt) to absorb the vapor, powered by heat instead of a compressor. We’re going through how the cycle works, the main components, the practical limits, and what it takes to keep the system running. Full Youtube video on fire-powered refrigeration: https://youtu.be/3sv7TBtHcgo?si=qB2NBwEFFEgI2xlk In this episode: How an absorption refrigerator cycles water as the refrigerant with calcium chloride as the absorbent Why calcium chloride is used instead of regular salt or other common absorbents like lithium bromide The roles of the generator, absorber, condenser, expansion valve, and evaporator How vacuum lowers the boiling point to produce cooling and why the system stays below ambient pressure Temperature limits of water as a refrigerant and why making ice is difficult How the U-bend and pressure differences create directional flow without a compressor Practical considerations for off-grid use, including supplementing a root cellar and managing heat input Power needs for pumps and fans, and options for using solar heat on the generator Challenges with scaling evaporators, absorber capacity, and monitoring pressures and temperatures Structural and vacuum-related details that affect building and operating the system _______________________________ Welcome to the Greenhill Forge Podcast, with Eric from the Greenhill Forge YouTube channel, and my buddy Amal, a fellow builder of many trades.

	4. Builders debate the houses that last 20 years vs 500	25 sept. 2026	01:31:50
This week we’re talking about building for longevity — what actually makes a house last 20 years versus 500. We compare modern American stick framing, European masonry, traditional stone, and natural building methods like cob, rammed earth, and straw bale, and why water, airtightness, climate, and skill matter more than the material itself. In this episode: Why old buildings are still standing and modern ones often aren’t How American stick framing works, and how it has changed Tight houses, moisture, mold, and the “Ziploc bag” problem HRVs, wood stoves, negative pressure, and indoor air quality Rain screens vs older tar-paper-and-siding assemblies Repairability vs 25-year wall warranties Speed, year-round building, and the trades skills gap Why buildings fail as systems, not as single products Modern European masonry and brick-as-rainscreen construction Dry-in time, cost, and US vs UK labor Brick veneer problems, window upgrades, and out-of-plumb stone walls Maintenance: masonry vs wood siding Long-lasting roofs: slate, clay tile, and standing seam Traditional stone, field stone, and lost mason knowledge Laying stone on its natural bed, and orienting wood the way it grew Natural building / “hippie building”: cob, rammed earth, straw bale, earthships, earthbags, and papercrete Thermal mass, overhangs, drainage, and climate-specific design Permitting, insurance, and hybrid builds Question of the week: the tool you most regret buying Tip of the week: spend money on tools that need to be precise _______________________________ Welcome to the Greenhill Forge Podcast, with Eric from the Greenhill Forge YouTube channel, and my buddy Amal, a fellow builder of many trades.

	3. Tractors & diggers: choosing small machinery for your property	18 sept. 2026	01:04:52
This week we’re comparing the small machines that actually get used on homesteads, hobby farms and small properties: compact tractors, skid steers, walk-behind tractors and mini excavators. We’ll go through the real jobs — clearing, grading, digging, gardens, compost, firewood, moving material — plus what to rent vs buy, implement cost and swap time, PTO vs hydraulics, fuel, maintenance, where these things get tippy or annoying, and what we’d buy first if we could only afford one. In this episode: Which machines are usually rented vs purchased Compact tractor (about 25-40 hp) as the most practical first machine Mini excavator as the strongest second machine for digging and tight garden work Why mini skid steers / dingos rarely earn their keep on a homestead Skid steer strengths (lift, attachments, speed) and weaknesses (price, fuel, visibility) Walk-behind tractors for small-scale market gardening Implement storage, used market and DIY builds Dealer vs cheap import, plus the US sub-25 hp emissions cutoff Listener question: starting welding Tips of the week CHAPTERS 00:00 - Intro: best small machinery for homesteads, hobby farms and smallholdings 00:51 - Start with the job: raw land vs established property 01:26 - Heavy clearing and big root balls.
