I ONLY use water as a lubricant on all my stones. When they get clogged I take a nail brush and hand dish detergent to them to clean them. When a carborundum stone gets worn I do figure 8s on a flat piece of concrete with lots of water to reflatten it. I don’t like oil because it gums up over time and is then harder to clean. I keep a carborundum and a Quachita stone by the kitchen sink for knives. I probably haven’t used the carborundum stone in several years. I scrub the Quachita stone at roughly 18-24 month intervals. It’s white, so it’s easy to see the steel accumulating. I can feel a noticeable difference after scrubbing the stone. This has been my standard practice for almost 50 years, so I’m not inclined to change it.
The third tool for the beginner is the Jigsaw. A jigsaw allows the user to cut curved and circular patterns in stock. Sure, a band saw will likely be more accurate and can cut thicker stock, but for the beginner, the jigsaw (sometimes also referred to as a Sabre Saw) can be perfectly effective. For versatility, choose an orbital-action, corded jigsaw that feels good in your hand and has an easy blade changing system.
I wouldn’t give up on Craigslist or garage sales.. For around $1K or less, you can pretty easily find the four big ticket items (TS, BS, Jointer and Planer) and have the extra $2K to spend on accessories, material, DC, other goodies, etc. The key is patience and persistence, and if applied correctly, you can have a fantastic setup for very little compared to purchasing new. If you are setting up a business, you don’t usually have the time to scour for good deals, but for a personal shop, there is no pressing need other than that itch to get something done.
