We take the postal service for granted, but it's not always reliable in other parts of the world. Both packages I received from South Africa were couriered .
That's a pure sin , I hate when the so called no nothings , when working with precision machinery even just moving them.Hold that result Nashtem, I have had another detailed look at your photographs of your drill, I think your machine It is not a Herbert but a PollardI can look up my catalogues and send you illustrations of both machines to South Africa if you can find any way of getting me a private message Both machines are very similar in design parameters, The give away is the lubricator on the front of the machine, and the nice heavy serated handle on the top of the cover tend to be a Pollard feature The last Pollard I came across was a double machine Two spindles on the one common bed , I have seen them up to four spindle machines I obtained one for a man and in lifting it on the crane, He looped the sling strop around the little chucks , Bent the spindles and totally wrecked the machine!
Adding the center pulley would also allow for both higher high end spindle RPM and lower low end spindle RPM, actual speeds would depend on the pulley sizes chosen. If it was my drill press, I would already be working on that...By the way... from looking at your last picture, it appears as that the center shaft has a cast iron bushing in which the center pulley would idle on. The center pulley would have an integral bronze bushing which would serve as your pulley bearing. In any case, if you just want 3 speeds, you’re good to go as it is. For 6 speeds, think about the center idler step pulley.
