. . . that solvent and glyptal stinks. I got this 4 speed all solvent washed, blow dried, bead blasted, blown off, solvent washed again, blow dried, washed in hot soapy water, rinsed in hot clean water, blow dried and a bit of WD-40 on the race. Then I cut down a thread insert, fitted and loc-tite'd in the case. Loc-Tite in stud. Glyptal case to seal. Then heat to 250 degrees for a bit to cure. Then carry-on brothers . . .
