Re: The next project

Today I managed some shop time, and made the bushes.
These are required because I am using steel for the plates.
Clocmakers use very thin bushings to repair worn clocks,but these may be beyond the skills of the person that this clock is aimed at. So i have made nice small Top Hat ones

Re: The next project

Can you go into more detail on Lathe gear indexing? Like construction of the bushing that connects the index gear to the lathe spindle.

Re: The next project

Im going to have to put this project on the back burner for a while as I have had a disaster with my boat engine that threatens my summer cruising.:nono:

Loads of work to do

Regards Brian.
 
Re: The next project

Cant work on the boat due to storms, so it's into the workshop to turn the main arbor. and do a trial assembly.

Re: The next project

The plate asembly, now fitted with bushes for the main arbor.
The 5 sided tapered broach is used to enlage the bushes from both sides, untill the arbor fits.

This is the only arbor that is placed by measurement. the others are placed by the fit of the gears.

{snip} It also mentions a device called the "Eureka continuous form relieving attachment" for reliving the form on multi-tooth cutters. It sounds like drawings may be available to make one, so the search continues...

Did you find the answer to this? The Eureka is drawn up in 'Gears and Gear Cutting by Ivan Law, Workshop Practice Series 17'

Re: The next project

At last the drill has arived, So i can drill the holes to make the lantern pinions.
