Hi Paddy Pup- Yes, hand reaming is actually my preferred method! It allows you to drift the hole any direction desired and is quite faster than having to secure the plate in a jig. The tooling for hand reaming is also quite a bit less expensive than a bushing tool. As for installing the bushing into the plate, I use a hammer and flat-faced punch to drive the bushing in place. Then I use a round-faced punch on the oil sink side of the bushing to seat it. Great questions! Thanks for asking!
ClockClass very assuring to hear, you also addressed a good point. To bush or not to bush. Complete novices like me would probably just bush with minimal movement. Thanks for the reply and good video !!
@@clockclass5480 I'm a journeyman T&D maker and I've been watching some of the videos and would have thought that the tolerances would have been tighter on clock pivots.My question is why aren't clocks jeweled?
@@ps-ff6yx Hi PS- Tolerances vary in clock movements. For example, wood works movements are very "sloppy" while jeweler's regulators are typically very "tight". Much has to do with the quality of the movement and whether it was designed for accuracy or simply an inexpensive, inaccurate, everyday clock. Trying to tighten up the tolerances on an average American mantel movement, for example, will mean stoppages due to plate misalignment, temperature changes, and/or depthing issues from slightly out-of-round wheels. You ask about jeweled bearings in clocks... Some clocks actually have jewels in the upper time train! These clocks are designed for accuracy and are more scientific instruments than everyday clocks. Mass produced clocks aren't designed for scientific applications and the cost to produce a fully jeweled movement would prohibit the average person from being able to afford it. The American clock industry was about "faster/cheaper" while maintaining some "quality". Even then, they made their clocks last too long! These became generational pieces, meaning a customer would buy one clock and have no need to purchase another for several generations. It isn't good business sense to make a clock which will last forever :-). Fully jeweling a movement could certainly have been done but it wouldn't have been economical nor guarantee a company's longevity. Great question! Thanks for asking!
