Seeking advice

I bet you converted grains to ounces or grams!!!! GROOVY MAN!!!! Those days are long over!!! It is interesting to note that the Patent Pending Number for the CO-AX is cast in the main base body of the press and visible from the operator's perspective!!!

And, I too have spent days looking for those f...ing jaw springs!!! Finally broke the bank, a whole $2.00 for 2 springs for conserving time looking for a rogue spring or two!!! Still have the 2 original springs!!! Must have scared them!! I will be purchasing the interchangeable jaw kits in the future!!! Right now, all may guns require the large rifle jaws!!!

I bought my Bonanza CO-AX B-1 model press (shell holder priming system) for $165.00 in 1982!!! I use the Sinclair hand primer instead for speed and a better feel for primer seating!! Bonanza also had the B-2 model with the adjustable 3 jaw priming system just like the Bonanza "Blue Ribbon" Primer Seater with "E-Z-Just" Shellholder!!!!

Still have the 1982-83 catalog, price sheets, decal, and box!!! In that catalog, there are 4 pages explaining the mechanical advantage of reloading presses!!! Those 4 pages look like pages out of my old college statics and engineering physics books!!! The article is for C type and CO-AX presses!!! With the basic info from this article and utilizing concepts of geometry, trig, torque, and vector mechanics, it could be applicable for any reloading press, including arbors!!!!
You're one up on me... I don't still have the box my Bonanza came in... All the rest though.
 
Changing dies is part of my safety sequencing. Single bottle of powder on the table at a time is another.
