Thread: Dyco Superfine 12" Table Saw

Looking good - I think the next time I do a machine I am going to:

1) Create a little shallow dam out of builders plastic
2) Then put the cast iron surface face down leaving a 2-4mm gap between the plastic and tabletop
3) I'll then fill the dam with Double Strength Vinegar or CRC's Evapo-Rust® & leave it to de-rust for 48hrs
4) Dry and clean up with a angle grinder wire brush

The other alternative is electrolysis which is tempting to setup.

I've not tried this before but have seen the results that a guy down in Sydney sent me doing a spindle moulder and it came up mint!

I've done a similar procedure as you have taken and it's fairly quick and straight forward with good results

The below is a pieces of heavily rusted metal plate which i had lying around. I had it submerged in some Double Strength Vinegar for about 48hrs and then submerged it in CRC's Evapo-Rust® for a further 24hrs. I think hit it with a wire brush and this is the result. What I liked about this process is it gets into any/every deep scratch or if you have pitting in the cast iron.

You can also put a thick cloth on the top of it, soak it with your rust removal agent of choice and wrap a plastic to prevent the evaporation. In the case of this table top it was more dirty than rusty.

BTW, I have mentioned earlier, it is worth to give the pH decreaser a try, it is more cost-effective than the vinegar per litre.

Cheers!

Ah-ha moment, thats legendary thanks. Evaporation has been a major issue! Will definitely try covering with plastic and pH degreaser thanks for the hot tip
