The Greenhill Forge Podcast

This week we're talking about building a welding workshop with a budget of $1000. The focus here is where to spend more, where to save your money, and having what you need to complete your first welding projects while keeping the entry price relatively low. So here’s what we’d get if we had to start from scratch!PDF with gear list images and links— https://drive.google.com/file/d/100zgt8ThYkUu_mCa9x3br4l55pOKmgRV/view?usp=sharingIn this episode:How to set up a functional beginner welding shop for about $1000What to spend more on, and where to save your moneySafety gear recommendations (respirator, helmet, jacket, gloves, glasses)Choosing a multi-process welder that does MIG, stick, and lift TIGWelding table and fixturing options, including making your own clampsAngle grinder, consumables, and what to spend more or less onDrill, bits, step bits, and basic measuring tools for a new shopTrade-offs between higher-amp welders and better supporting toolsWhat you can realistically build or do with a $1000 setupSpecial mention: *Tajima chalk line https://link.amazon/B0dbb8DcZAmal's List*Half Mask P100 Respirator https://link.amazon/B0gAqKhKa*Safety Glasses https://link.amazon/B05qMxwc9*Yeswelder Welding Jacket https://link.amazon/B08rEGjDo*Yeswelder Welding Hood https://link.amazon/B0hnFmDwg*Tillman Mig Welding Gloves https://link.amazon/B05iIJQOg*Vevor Vise https://link.amazon/B08RaRync*Vevor Welding Table https://link.amazon/B08XtXyx1*Bar Clamp 6 Pack https://link.amazon/B03ukoYTV*5/8'' Round Bar For Making Clamps https://link.amazon/B08paB3Q5*Irwin Clamp 2 Pack https://link.amazon/B00wBvgOJ*Craftsman 1/2'' Drill Cordless https://link.amazon/B067X0BWR*Cobalt Drill Bit Set https://link.amazon/B079pQeXC*Bosch Gws8-45 Angle Grinder https://link.amazon/B07TYPJAz*Grinder Wheel/Cutoff/Flap 26 Pack https://link.amazon/B0dGSSHF1*Grinder Wire Wheel 2 Pack https://link.amazon/B0itH3D4a*Carbide Scribe 4 Pack https://link.amazon/B09m93Pyj*Fastcap Measuring Tape https://link.amazon/B0ebbeLdn*Irwin Combination Square https://link.amazon/B05t28hIN*Digital Calipers https://link.amazon/B07q5pvLz*Digital Angle Finder https://link.amazon/B09pn07vS*Yeswelder 160 Amp Mig/Stick/Lift Tig https://link.amazon/B05ig9iJv*Stick Welding Rod 3/32'' 5lb https://link.amazon/B09U9d3QY*Flux Core Mig Wire .030 https://link.amazon/B0hWN8Vh7*30 Amp 220v Extension Cord https://www.amazon.com/dp/B0DYP5W4XG/?tag=greenhillfo0a-20*Mig Gun Consumables https://link.amazon/B0cxvwJVB*Mig Pliers https://link.amazon/B03ItsGi4Eric's List*ARCCAPTAIN 200A Welder https://link.amazon/B01Ywlfry*YESWELDER Flux Core Wire https://link.amazon/B0ajWoPrn*Welding Accessories https://link.amazon/B0hNU11sR*ARCCAPTAIN Helmet https://link.amazon/B0eHQBEQI*3M Respirator https://link.amazon/B0h0OMyHg*3M P100 Filters https://link.amazon/B0bd3CuCj*NoCry Safety Glasses https://link.amazon/B0fdZ317N*Ear Plugs https://link.amazon/B0i6sYlFx*Work Table https://link.amazon/B03aKpr1L*C Clamps https://link.amazon/B0iOluwF6*Magnets https://link.amazon/B0gyyMxHb*36" F Clamps https://link.amazon/B0cVC35Tw*DongCheng Angle Grinder https://link.amazon/B00w37UoO*Cut Off Wheels https://link.amazon/B0dY9t6X0*DeWalt Grinding Disc https://link.amazon/B0eY2DOnx*Drill https://link.amazon/B01oeVcN8*Drill Bits https://link.amazon/B00qunxd6*Step Bits https://link.amazon/B0e7yfBhW*Cutting Oil https://link.amazon/B0a0ZVPpO*Calipers https://link.amazon/B09Il7Vw4*Squares https://link.amazon/B0fzBpDQd*Scribes https://link.amazon/B04hTVPLo*Komelon Measuring Tape https://link.amazon/B09H39vRr*Angle Finder https://link.amazon/B0hpNRqj2Welcome to the Greenhill Forge Podcast, with Eric from the Greenhill Forge YouTube channel, and my buddy Amal, a fellow builder of many trades.In this podcast we’ll talk about where the real world meets experiments in alternative energy, wood heating, metal fabrication, off-grid engineering and self sufficiency, so expect discussions about workshops, tools, fabrication, building, homesteading, and what it actually takes to make those dreams real.We’ll answer a listener question (almost) each week, so send yours to https://forms.gle/zNzKTtjDnBEupLBQA.WATCH the podcast on Youtube at https://www.youtube.com/@GreenhillPodLISTEN to this podcast on all your favorite podcast platforms.See you next Friday!CHAPTERS00:00:00 The $1000 beginner welding shop challenge00:00:52 Amal’s list, starting with safety gear picks and what’s worth spending on00:08:00 Fixtures, table, and clamps- cheap vs name-brand00:15:33 Drill and drill bits- where to spend more00:18:00 Angle grinder and abrasives- name-brand

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=qB2NBwEFFEgI2xlkIn this episode:How an absorption refrigerator cycles water as the refrigerant with calcium chloride as the absorbentWhy calcium chloride is used instead of regular salt or other common absorbents like lithium bromideThe roles of the generator, absorber, condenser, expansion valve, and evaporatorHow vacuum lowers the boiling point to produce cooling and why the system stays below ambient pressureTemperature limits of water as a refrigerant and why making ice is difficultHow the U-bend and pressure differences create directional flow without a compressorPractical considerations for off-grid use, including supplementing a root cellar and managing heat inputPower needs for pumps and fans, and options for using solar heat on the generatorChallenges with scaling evaporators, absorber capacity, and monitoring pressures and temperaturesStructural 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.In this podcast we’ll talk about where the real world meets experiments in alternative energy, wood heating, metal fabrication, off-grid engineering and self sufficiency, so expect discussions about workshops, tools, fabrication, building, homesteading, and what it actually takes to make those dreams real.We’ll answer a question each week, so send yours to us at https://forms.gle/zNzKTtjDnBEupLBQAWATCH the podcast on Youtube at https://www.youtube.com/@GreenhillPodLISTEN on all your favorite podcast platforms.See you next week!_______________________________CHAPTERS00:00:04 Absorption refrigerator design overview 00:01:05 Importance of cooling and off-grid power sources 00:02:36 Choosing water and calcium chloride over other options 00:03:05 How calcium chloride absorbs water vapor in a closed system 00:05:26 Exothermic reaction when calcium chloride hydrates 00:06:30 Calcium chloride as road salt and a concrete accelerator 00:07:47 Water as the refrigerant and the absorber’s role 00:08:08 Cooling the absorber to maintain absorption capacity 00:09:26 Multiple heat cycles compared with vapor compression 00:10:23 Expansion valve, pressure drop, and one-time coolers 00:11:48 Generator and absorber replacing the compressor 00:13:09 Lifting refrigerant with heat and gravity feed 00:13:41 Water’s heat capacity advantages and drawbacks as a refrigerant 00:14:08 Latent heat and phase change explained 00:15:46 Boiling point changes with pressure and elevation 00:16:54 Using vacuum to lower the boiling point for cooling 00:17:58 Freezing limitations of water as a refrigerant 00:19:03 Using the system to supplement a root cellar 00:19:43 Achievable evaporator temperatures and ice-making challenges 00:20:24 Issues with antifreeze additives in the system 00:21:47 Flow through the condenser, needle valve, and evaporator 00:22:05 U-bend as a check valve and pressure separation 00:22:57 Running the generator leg with the valve closed 00:24:18 Split of flow between the evaporator and recirculation 00:27:34 Design process and differences from industrial systems 00:28:00 Sizing the U-bend for the pressure differential 00:29:07 Ambient temperature effects on evaporator performance 00:30:35 Enclosing the evaporator and accounting for fan heat 00:31:45 Adding evaporators in parallel and absorber capacity 00:33:29 Limited published data on calcium chloride as an absorbent 00:36:22 Off-grid challenges with compressors and mechanical energy 00:37:13 Power draw and solar options for heat and pumps 00:39:00 Solar heating the generator and thermal storage ideas 00:41:11 Solar irradiance and concentrating sunlight 00:42:45 Solar panel efficiency versus direct heat collection 00:43:30 Using solar-heated fluid to drive the generator 00:44:37 Potential cooling capacity for small units 00:45:57 Sensors, Arduino modules, and voltage readings 00:48:26 Pressure sensors, absolute versus gauge pressure 00:50:07 System pressures remaining below ambient 00:51:15 Structural deflection and reinforcement under vacuum 00:52:58 Vacuum distillation and related applications 00:56:35 Water level shifts between generator and absorber 01:00:06 Water column acting as a barometer

This week we’re talking about alternative alternative energy — ways to run engines and produce power that aren’t the usual solar panels or wind turbines. We go through waste vegetable oil and biodiesel, wood gasification, small-scale ethanol, methane digesters, and a few mechanical systems like wind pumps, water wheels, trompes, and Stirling 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.In this podcast we’ll talk about where the real world meets experiments in alternative energy, wood heating, metal fabrication, off-grid engineering and self sufficiency, so expect discussions about workshops, tools, fabrication, building, homesteading, and what it actually takes to make those dreams real.We’ll answer a question each week, so send yours to us at https://forms.gle/zNzKTtjDnBEupLBQAWATCH the podcast on Youtube at https://www.youtube.com/@GreenhillPodLISTEN on all your favorite podcast platforms.See you next week!_______________________________CHAPTERS00:00:14 Overview of alternative fuels and mechanical energy systems00:00:58 Running older diesel engines on waste vegetable oil00:02:02 Cleaning and filtering waste vegetable oil00:03:30 Dual-tank veggie oil conversion with preheating and purging00:05:07 Making biodiesel from waste oil00:06:35 Sourcing methanol and its cost for biodiesel00:07:50 Biodiesel compatibility with modern engines and seals00:09:04 Mixing vegetable oil with diesel or kerosene as a simpler option00:13:31 Using multi-fuel generators and military equipment on alternative fuels00:16:41 Filtering methods and removing water from waste oil00:19:04 Trade-offs between pre-processing fuel and engine complexity00:23:54 Rebuildable injectors and choosing older mechanical diesel engines00:27:00 Running tractors and farm equipment on vegetable oil00:29:25 Do indirect injection diesels handle biofuels better than direct injection00:31:00 Availability of waste vegetable oil00:33:46 Wood gasification and producing syngas for gasoline engines00:35:56 Small-scale ethanol production from sugar or starch crops00:37:02 Fermentation, distillation process, and energy input vs output00:40:34 Using solar heat to reduce energy needed for distillation00:44:00 Dehydrating ethanol with molecular sieves for fuel use00:46:57 Separating methanol heads and monitoring distillation temperatures00:50:41 Ethanol yields per acre and the role of farm subsidies00:53:35 Methane digesters that turn farm waste into burnable gas00:56:20 Mixing manure, scraps, and fat as digester feedstock00:57:45 Batch versus continuous digester systems for daily use01:02:38 Mechanical windmills and water wheels for pumping and workshop power01:05:07 Using water wheels to grind grain or run equipment01:06:48 Trompes that use falling water to create low-pressure compressed air for forges01:10:05 Stirling engines that run on heat differentials01:13:55 Listener Question: Advice for starting out today01:17:25 Tips of the Week: Trade school and trying new things
