Darn humidity

[MattF]

it does leave an impressive finish putting to shame my splash a bit of oil on it and wipe it with an old rag approach.

Is it still holding up okay on the changewheels?

I have not noticed them not to be, that said my garage is not too bad for condensation and I do like to keep everything on the Drummond well lubricated so perhaps not the best test.

I used to get flash rusting in the workshop. I tried dehumidifiers but bought the wrong kind, should have bought dessicated type as its cold. Also, at the time there was too much uncontrolled ventilation so I wouls have been dehumidifying Yorkshire.

Now I have it largely under control by heating the workshop, I found 7c to be the optimal for my location and conditions. I have a second hand pellet boiler and fan coil units. Here's the temp tonight, you can see the heating kicking in.

I also use various unctions, Liberon wax on woodworking machines and various oils on metalwork machines but don't need to go to heavy slideway oils now I heat it.

The workshop is clad in 60mm kingspan metalclad panels, but I found a slight gap between eves and roof in some places, hard to see as its hidden behind one of the beams on the inside and box gutters on the outside. I've been painting the beams then sealing this up, should have been done by now but I'm lagging behind a bit.

The plan is to reuse the old heat recovery ventilation unit from the house to provide controlled ventilation then I can use a dehumidifier so I can lower the temp down a few degrees. The HRV also does some moisture removal so will see what the relative humidity is when fitted.

Warmer air rises, so removing the leak(s) at the eves will doubtless much improve the situation. Warm air going out must be replaced by colder, damp air (lower down)?

What oil do you spray on? My stuff is all small tools really but some metal on the pillar drill and bandsaw tables could do with longer term treatment.

Tool wax seems to work well. I used a squirty can of engine oil to rub on the vices this evening in addition to the wax. (May add strips of wax paper on top of the oil if I get around to restoring a few more vices)

Best stuff I ever used was some sort of aerosol wire rope lube. Possibly Rocol. Thick black stuff. Elliott Sturdimill and may Colchester Triumph were good for 20 yerars. Wipes off easily with wd40 and a cloth. I used it so long ago I can't remember the right one though
My warehouse is a nightmare - usually about 85 to 95% humidity. Being close to the sea doesn't help. My old place was about 5 miles inland. Still cold and unheated but no rust or very little.
I have to constantly bury my stuff in oil.

This strategy has worked well for me too for a 9'x12' insulated shed. I used to blast a 2kw fan heater when I was in there and turn it off when I left, now I have a 700w oil filled radiator and accept a low average temperature, sits at about 8-10 degreesC, flash rusting on lathe chucks was the biggest issue, this has now stopped. I'm sure a higher temperature wouldn't cause any issues in my shed but the cost of heating just isn't worth it.

What do you use for logging your temperature?

What do you use for logging your temperature?

I use a one wire temp sensor, they are addressable individually so you can poll them using a bit of python code on a raspberry pi, I then shove the data into an influxdb time series database and display it with Grafana.

You can read about one wire sensors and daughter boards for raspberry pi here https://www.sheepwalkelectronics.co.uk/1wire_basics.php

I must do a "howto" on the rest of it one day.

It usually gets blown in on the windward side using the same gap, this pressurises the barn and it seeps out the leeward side. I used a wooden spill to generate a bit of smoke to investigate the airflow.
