Shop projects update 4/11 - Machining a small homemade alcohol burner part 3 (finishing touches and testing)

HakasaysApr 11, 2021, 11:21:51 PM

Yesterday, I used some scrap brass to bend together a crude fuel tank to hold the alcohol for the burners.

I still needed to fashion a fuel cap+ring as well as solder the whole thing together. I haven't done much silver-soldering before so this was good practice.

Threading a piece of brass and knurling one end

One part down. Now to make the ring adapter to fit it to the tank

Ring finished. Took a little bit of tinkering to get the threads to fit properly, but looks good

Silver-soldered the ring to the gas can and drilled a hole. It took a few iterations with the solder before it could be made watertight

Now we're cooking with isopropyl alcohol

Testing the burner on the model steam boiler

I'll call that a victory :-) It seems a little slow but it does raise steam.

Overall it came out OK. The burners at the back have a tendancy to go out, probably from a lack of oxygen. And I'm not sure the fuel is burning as hot as it should; the shop gets the 'burning isopropyl' smell when it's running.

Also needs a stand of some sort to keep it from falling down, but I'm gonna call it 'good enough for now'.

Anyway, hope you enjoyed it😄
