A Beginners Clock

Re: The next project

So lets get started by introducing the main tools that you have not got.

The fileing attachment is a very useful tool for making flats , squares,etc in the lathe.
View attachment 43054

It fits on the vertical slide so the depth of cut can be adjusted.

Did I hear a comment that we dont have a vertical slide
Take a close look and you will see that its the compound slide, back to front, on a angle bracket.

So all we have used so far is a few bits of metal ,Mostly scrap, and we have got some useful tools

Re: The next project

When I try to open your attachments I get an invalid attachment note???

Re: The next project

Thanks Bill will try again.












I hope this is better

You're OK now Brian.

Re: The next project

So we will continue. the next tool is the milling spindle.

This was made from sq tube from a scrap steel chair.

2 brass pipe fittings.

A piece of scrap plate

A length of steel bar from the local blacksmith (free)

A scrap steel punching.



This fits on the vertical slide and is driven by a motor bolted to the end of the lathe bed.




If you are wondering how the motor came to be in my list of tools ??? it came of the bench drill.

Re: The next project

We nave coverd the gear cutter, so the last problem on the lathe is to index the gear blank

This will be done using the 80t and 60t gears that came with the lathe.



The lathe is now fit to cut gears so we can turn our attention to another usefull item.




This is a backplate for the chuck .



It fits into the centre hole of the drill base very useful for spacing holes.





With the angle bracket it can also be used verticaly.

Other small tools as we go along.

Re: The next project

Ok so now we start the real work.

The clock has 5 gears 2 escapement wheels and a ratchet that must be made from engraving quality brass. may be the ratchet may possibly be of mild steel to keep the cost down

So I started on the ratchet as it has the smallest number of teeth.And the cutter worked well thro the 1/16" blank in one pass.no problems.

Re: The next project

Wonderful start to another obsession. Thanks a lot!

There are enough projects in the works here that I can convince myself to just watch this thread rather than feel compelled to go digging for metal to use.

Re: The next project

Having proved that the cutter works. the next job is to make the escape wheels while we still have the cutter set up. so 2 blanks are fitted to the arbor, so we can cut them as a pair. the radial faces are cut first then the back slope.

Re: The next project

So the next job is to cross out the wheel to make it lighter, and better looking.
I am trying to keep away from the traditional method because, I feel that a lot of fuss is made of this by clockmakers, and it deters those new to engineering.




Off to the drill.

A little bit of sawing and simple fileing and we have one of our wheels nearly finished
