I am looking at the metal mesh face shields and thinking they will stop molten iron like nothing is there. Molten iron looks too much like water to be stopped by metal mesh. Happy to be proven wrong.

Wear spats. The versions made for foundry/welding cover the boot laces.

I have also used Nitric acid but with all the problems above. Also Nitric acid is very dangerous. Take a lot of care if using it.

Hi My Denford has 3 point supports for both the lathe on the stand and the stand to the ground. There is no adjustment for twist.

Hi The Denford Viceroy is definitely better built than the Boxfords. Hardened chrome bed, more/better accessories, separate lead/feed shafts as standard etc etc.

That sounds fantastic :cool:

Hi This is easy to solve. Just send me the chuck and your problems are over. :)

Hi Nice work. You should try it without the accumulator. I suspect you won't need it.

Hi I have been through the process of adjusting bearing pre-load on my Denford Viceroy lathe. Take a look at this link to see what I did Headstock bearing adjustment

I have a Denford Viceroy and a much larger Nardini lathe. The lighter Denford sits on threaded rubber pads because it was too low for me. The heavier Nardini sits on 25mm dia threaded steel feet straight onto the concrete. No damage to the concrete. No vibration into the house through the...

Hi Take a look at Dan Gelbart's uniflow steam engine here. It sounds terrible, but is the best uniflow design I know of. If I was going to build a uniflow steam engine, I would build to the Dan Gelbart design.

Hi Industrial control systems aim to identify failure modes (short, open circuit, failed sensor, stuck sensor, power failure, etc etc) to then identify a fail-safe response. The aim being to ensure that a failure brings the equipment to a safe mode of operation (which may include turning it off).

I resemble that remark. I have a Masters Degree in Electronics Engineering, two lathes, a Deckel clone milling machine and a double garage too full of tools to fit a car. If you look in the world of 3D printers (for example) you will find many others like me. I like the idea of auto boiler...

There is a theory that pulsed fuel flow creates balls of fuel that increase turbulence and the flame front surface area. Without evidence, I don't think it would be a good approach. I note that real gas turbines and steam boilers use constant fuel flow to maintain a steady flame. Pulsed...

That is what I plan to do with other parts. For the part I have in mind, just making the wax pattern would be a challenge. I don't know if I can get wax filament that will work with my Prusa printer. I am not setup for investment casting, and to do so would cost me too many $$$$. I will...
