Logosol drying kiln

30 September 2017, Woodturning in practice, Would you like to leave a comment?

I’ve been planning to build my own drying kiln for quite some time, so I can process smaller batches of wood. With so many ideas and theories available, I eventually chose a kit…

After much research, I discovered the Logosol VT3, which is aimed at the smaller business. The combined heater and fan is quite efficient and takes up little space. These can be purchased separately, for those who wish to make their own kiln box. The main box is supplied in the flat and made from sheets of 50 mm thick polystyrene insulation board. These need to be glued together and screwed with the fixings supplied.

Loaded up and ready to go. The apples are just an experiment!...


The kiln works in two stages, so that the wood dries evenly and with no cracking - I’m still experimenting with the timings and will hopefully end up with some perfectly dry timber in four weeks time!

The first stage requires the base to be filled with an inch or two of water. The heat is set to about 60 degrees and then left for 2 - 4 days. This high temperature creates steam, which helps to open up and penetrate the natural pores in the wood. The subsequent drying process will be slower and more even. The water is then drained out for the second stage and the heat reduced to about 30 - 40 degrees. Within about 3 – 4 weeks, the timber should be thoroughly dry.
