I'm posting this here, as this is the best place I could find. It covers hand tools and power tools.

I have a free standing shop that over the last couple of years has seemed to have an increased moisture content. The shop has a concrete floor with one half epoxied. I'm in the process of putting a wood floor on top of the concreate which should help with a couple of issues. Those issues being standing for long periods of time on concreate and inslutation for the cold Upstate NY winters. I'm thinking about even adding a dehumidifer.

Basiclly any and all metal tools have surface rust that seems to form over time. I do my best to spray them with T4 and apply wax coatings. I know - if I spent more time in the shop working I would have this problem. The shop has an air conditioner, however, we haven't really had to many days that it has needed to be on.

I'm in the process of cleaning the shop and will be adding some new cabinets to place my tools in this weekend. Is there anything that can go into the drawers or cabinets that would help to decrease any rusting issues?

thanks

With rust problems the first situation to address is humidity. It seems your regimen of taking care of the tools (cleaning/waxing) is no having much of an effect.

I would say your primary concern is humidity control, and I say that from your statement "Basiclly any and all metal tools have surface rust that seems to form over time."

Cement is a natural wick for water so any moisture under the slab will transfer through the slab and into the room. I would consider running the air on a continual basis until you get the humidity under control. You can keep the shop at a very comfortable temperature and still maintain humidity control.

Sealing the rest of the cement with epoxy, then laying your vapor barrier down and the wood floor would help control this invasion of moisture.

Is the shop well insulated with a proper vapor barrier on walls and ceiling?

As for the drawers and cabinets, silica gel packets work and can be re-constituted in the microwave.

But I am thinking once you have the humidity under control your rust problems should basically disappear to the occassional.

Have a wonderful day.

Bud,
The rust prevention work is something that has to just become part of your regular woodshop routine like sharpening and tuning. As you mentioned frequency of use, dehumidifiers and AC wil l just help keep the rust at bay.. But you'll still need to wax and steelwool the surfaces to keep them shiny and new looking. Luckily here in Colorado, being around or below 18% relative humidity my rust issues are only associated with sweaty hand prints and beverage condensation rings.
One product you could try adding to your toolbox, drawers and wallcabinets is humidity absorbant silicon packets. Garrett-Wade use to sell them.. and I'm sure many other retailers have them for sale. I've heard great things about them, but they can get expensive.

When I lived in Mass. I used Camilia Oil from LN to wipe down my tools after using them. Worked great and just became part of my clean-up process.

What season does the rust tend to be the worst?

Rapid fluctuations shop temps tend to increase condensation, especially for large chunks of cast iron.

Lowe's sells drawer liners that has some of of that rust preventive in it. Its similar to a product that gun owners put into their safes.

For years it use to be spring, however, the last couple of years it seems to be more summer rust issues than any other time of the year.

Spent most of today with steel wool, T4 and wax going over all the large equipment - no matter what the metal. The cast iron got the most TLC. Also pulled the 20" planer apart and oiled, lubed and everything else.

Tomorrow I'll finish the tool stand, cabinets, and lay out the handtool positions. Monday I'll take a little time and steel wool, t4 and wax them guys up.

The insulation is fair - walls are good, doors fair (1sm one to be replaced), windows will be replacing with Low e argon filled x4, working on the sub-floor so that should help. Then I'll add more to the ceiling in the fall.

I'll also follow up with the other suggestions you guys gave. In checking the other forums this seems to be a problem this year.
