Recycled DNA

Looking good, And looking forward to seeing the finished device. Keep up the good work.
 
quick update.....not much achieved, had terrible job to get decent finish on copper turning.
Reground tool angle and eventually managed to achieve decent finish. But wasted some copper along the way.....


making 510 adjuster bar, drilled and tapped M4 for 510 tip

Good effort mate headaches with standing know this'll be Tha bullocks when done :)
 
When I was at school, I remember a kid trying to trim up the copper boiler for his steam engine on the lathe as he was too fucking idle to do it the same as the rest of us by careful use of a file. Result was, the tool dug in and totally minced his boiler tube. From a class of about 20, there was only about 8 working steam engines. Mine didn't work until I took the brass piston/cylinder to work and instead of spending my day doing the instructors bidding, popped my piston in the lathe and got rid of some of the scoring from the worn school lathes. I really loved my little steam engine once it was working, I priced up the Mamod engines and even back then they were over the £100 mark.

Sometimes a combination of machines and manual labour is the only way to get things done right
You treasured that engine because of the effort you put in I hope some of this effort I'm putting in can benefit someone else
You are only seeing the main processes here there is also a fair bit of filing and polishing going on in the background
I've been looking at sterling engines recently
But I've got to finish this mod and at least 2 mech mods first
Answer to copper is a tool with a big positive rake and high speed small cuts low feed rate
Kerosene coolant helps but I don't think they'd appreciate me filling the lathe with light oil :)

back to the mill

another update....managed to get offcut of polycarb clear guard sheet,
mill out bezel for display/insulator for side plate.
also cut pieces to approximate size for case ready for milling, drilling and tapping....
she's gonna be heavy.....

Sparky that's some nice work :goodjob:
 
Nice work & I thought doing it by hand was a lot of work.

If you use a flat bus-bar for the +ve you get free reverse polarity protection with the Sony (& most other) batteries: the -ve would not make contact with a flat surface because the heat-shrink sleeve on the bottom would prevent it.

Good tip and yeah it seems more work because discounting the pcb and a couple switches I am trying to recycle the materials as far as possible
