Just got myself an Alexandra 3a pantograph....this is the one that looks identical to the deckel gk-21....and is a 3d pantograph/die-sinker. There is one thing puzzeling me in. in the intruction manual it recomends that you pump vaseline (PETROLIUM JELLY) into the spindle/cutting head. I cant see vaseline having any antiwear properties..... Has anyone used one of these machines .......can they recomend anything better than this....bearing in mind that the spindle can turn at up to ten thousend rpm. SOME OF THE DECKEL VERSIONS DO TWENTY THOUSEND RPM. Also has anyone got a cam profiling atachment and a setting bar for this machine....or any other atachments come to think about it. All the best.........mark
