Send for my CD Disk $15. Has 9 drawings, results of 296 recharged magnets, 19 pages of instructions from magnet removal through installation on flywheel and balancing. This is restoration, not grinding. Slip on coils are made of two 50 foot spools of Home Depot #14 wire charged with a $40 Harbor Freight battery charger. Max Treece
Each coil has 144 turns. The end test fixture is not used because the ends are often malformed. In the engine, the magnetic flux is induced from the side. A plastic pail is hung on an open eye hook screwed into the keeper (flux) bar. Weights, lead or rocks, are placed in the pail. A small stream of water is poured until all drops 1/8 th inch where it is caught. Dip out an estimated amount of water that went in corresponding to your reaction time. Slip the keeper bar out the slot and place the pail and bar on the $17 Harbor Freight digital scale.You really need my CD with engineering drawings to make the mandrel wind the coils properly the first time and get them off the mandrel.

Very nice Max! Nice design. It appears to me the high weight is from the area being pulled on the side test.
Ron's method of striking the magnet on steel holding the magnet by the V is important, they are sometimes cracked at the V.
What I wonder is grinding the ends leaves a close foot print area for testing as long as the block being pulled is flat. Only magnets used for testing need to be ground.
Your side test is probably a better test.
