I can fine tune the fit after cutting sample pins by changing the 0 setting on my y axis (the usual z axis). Cnc dovetail software ltd. I have less experience with half blinds, as through dovetails are so much easier to cut by virtue of the excellent cut one gets with solid carbide spirals, that I now use through dovetails in some applications I formerly used half blind. Two inch wide parts are machined in well under a minute each, and I often have a router table set up near by, to cut grooves for bottoms, to keep me busy while the dovetails are cut, so my time cutting them is really only that required to clamp and unclamp them. ![]() Janusz PawliszynThis article describes the application of solid-phase microextraction (SPME) to the recovery of manufacturing by-products and impurities from an illicit drug seizure. The preparation chosen for examination using this technique contained 4-methoxyamphetamine, an hallucinogenic amphetamine that has been encountered frequently in South Australia. Compounds found in the PMA preparation included 4-methoxyphenol, 4-methoxybenzaldehyde, 4-methoxyphenyl-2-propanone, 4-methoxyphenyl-2-propanol, 4-methoxyphenylpropene, and (tentatively) 4-methyl-5-(4′-methoxyphenyl)pyrimidine. The presence of these compounds suggests that the active drug was prepared from 4-methoxybenzaldehyde via 4-methoxyphenyl-2-propanone using a Leuckardt reductive amination.

And Pawliszyn, J. (2010) Solid-Phase Microextraction, in Handbook of Sample Preparation (eds. University Of WaterlooIn this instance, SPME was found to be a simple, rapid, and non-destructive recovery technique that gave results complementary to those provided by conventional liquid-liquid extraction. There is an indication that SPME might find application in profiling of illicit drugs.
