During the construction of my Mightymill CNC machine, I needed precision granite reference tools. Premium parallels cost $500 to $3,000 — way too much for a hobbyist budget. So I went looking for alternatives from China.
Quality Check
Upon unboxing, I was impressed by the visual finish and clean chamfered edges. Each parallel and granite square came with a factory measurement certificate verifying 000 grade quality.
Verdict
Budget-friendly alternatives can provide satisfactory results for hobbyists and small-scale machinists. I ordered extra sets for friends in the machining community who were equally impressed.
