The 0.05mm tolerance was held on a precision inline-4 model engine I designed and machined entirely from scratch. 26 components. The crankshaft, pistons, engine block, connecting rods — all machined on manual lathes and mills to that tolerance.

It’s the tolerance that taught me what precision actually means in practice — not on paper, but in metal. That’s the standard this service is held to. Every order, every part, every time.

0.05mm exists because the existing options are too expensive, too opaque, or simply don’t understand what engineers actually need from a print.

I’m Ibrahim — a mechanical engineering apprentice at Rolls-Royce and the person behind every 0.05mm order. I’ve been designing and building things since I was four: metalworking, fabrication, woodworking, precision tools.
