Rolling Mill - Cleaning off surface rust.

🤙nice & relaxing music! great machine you get there Marius!😉🙏

[@engraverhand]

Thank you sir! :-) Making music is a nice break.. but yea, the machine is a beast! Can´t wait to start using it! Unfortunately the other day the condenser broke, so I had to take out all the motor as it was well hidden inside the motor box.. and a little hunting finding a matching one. But it´s a good opportunity to clean it well inside too, and I got to know a few things I didn´t knew.. so all good, and I have time to polish it a little more :-)

Great video! I restore allot of old machines. Something ive come to find the very best to use is evapo-rust. Amazing stuff. Doesnt hurt the finish and its non toxic. Happy restoring!

[@engraverhand]

Oh cool! :-) Thank you very much! I’ll write that down and see if it is something we can get here in Spain.. :-) Don’t know if you saw the comment about the condenser breaking down.. A little challenging finding a new, but in a way kind of happy it did as I learn so much more about the machine as I had take so many things apart.. and a good opportunity to clean and restore it even better :-)

Great tips, it´s difficult to get in those grooves.

It is and still took a while, but they start to shine bright.. :-) Glad you found it useful! :-)

hi marius mellebye, which are the characteristics type of engine does from this model cavallin 100/55 rolling mill operate ?

[@engraverhand]

hi there, I have some photos of the motor, but it´s a lot of text.. so if you want feel free to send me an email at [e-mail] and I can send you some photos I took when I was changing some parts :-)

Is that shoe lace, if not can you specify what sort of thread is that I have a same problem

[@engraverhand]

Hi there, no ot´s not a shoe lace, but probably a round shoe lace might work too, but I have not tried. I had some round cotton lace.. I wanted to use cotton as I think it would be more gentle to the metal. Maybe that is not necessary, but I did just in case.. :-) Obviously a more thin cotton thread for the smaller grooves. Just on the side.. for my flat rollers, I found a round metal piece and cut it the exact same width as the roller and put a piece of 800 sand paper around it and smeared on some metal polish and started the machine.. slowly polishing the flat rollers down, but keep an eye on it and maybe turn the sand paper. After a little time, change to a 1000 grit.. then maybe 1200 grit to get them smooth.. mine had some dents in it, but starts to be flat and shiny :-)

@@engraverhand thanks for that info.. I did try that method and it has cleaned alot but not completely In my excitement, I fear I ended up buying an old 100mm Fili Cavallin combo rolling mill. When I purchased it, it appeared to have only superficial rust on the rollers. However, after bringing it home and spending a few hours disassembling and cleaning it, it looks better but not perfect. The mill is quite old and doesn't even have a gearbox, making me feel somewhat foolish. I've noticed some black corrosion marks, which aren't dents but rather something on the surface. There are only a few marks left, some of them being in wire grooves/cavities possibly due to the previous owner not cleaning it properly after rolling, causing silver oxidation. While I've managed to clean most of it, some of those black marks remain. Do you have any advice on how to remove them?

[@engraverhand]

@@criss1256 I have never had any of these "black marks" so difficult to know what it is.. but if it does not make marks in the wire or sheet you are going to roll, I would not worry too much.. My sheet roller is pretty good, but not 100% perfect.. but I can´t think of a situation where I would not sand it to a more shiny finish anyway, so I´m not so worried about mine at least :-) Without gear you should be alright with fine gold and silver, but anything harder will give you a good exercise :-)

@@engraverhand tbh I haven't tried rolling a sheet or a wire yet I will give it a go and see, thanks for responding ☺️
