My Wooden geared clock

Lead is lead but i was hoping to save some money. 8kgs each side so 16kgs

Give me a couple of days and I will see how much lead I have. (have to find where I've stashed it but I reckon I've got 30 or 40 kg). Have you thought of making custom weights and pouring molten lead into them? Even a turned wooden sleeve that a cast lead sausage could slide into.

G'day Dean,
One thing to consider is that you will need a larger cylinder to fit a given mass of shot than what you would need for a cast lump of lead. There is an aweful lot of air between all those little balls, taking up lots of room. I think from memory, about 1/3 of the space is air! If you were to melt the shot down to be cast into a solid cylinder, your weight would be 2/3 the size for the same mass.

Also, if you drop the weight and it spills, it makes a BIG mess to clean up!!

Other than that, shot would be fine!

Cheers

Yes thats what I want to avoid....ideally I need the weight boxes as small as possible to enable the clock to run as long as possible!

I have enough lead here and if you want I can cast it into the boxes for you.

[1964deano]

Thanks Chris....had been researching that today. I have to make some boxes, preferably out of alley for the lead to slip into. Let me know how much if money is involved.

I will be glad to get more junk out of my workshop, buy me a beer sometime.

These holidays I have set myself a task of producing the final prototype of my weight wheels frame. This frame holds the wheels that the weights will hang from. In this pic i am making some fine adjustments to the pulley centers that were drilled by hand. This time i am having the CNC machine the holes so they are more precise. More soon.
