There are clear advantages in fitting a gutter system to your log cabin. The two main benfits are :
And should your cabin have a reverse apex, ie, the ridgeline runs left to right, then guttering on the eaves will stop the rain water dripping off the roof and onto your head when you enter the cabin !
Fitting gutters is very straight forward. Whichever way your cabin is contructed, the gutter brackets will be secured to part no. 39b
Consider first the end of the gutter that will take the collected water away (either onto the ground or into a collecting vessel) this end needs to be the lowest end. Conversely, the opposite end needs to be attached at a higher level - this will ensure the water flows to the drainage end correctly.
Attach a string line between the first and last bracket - this will show you where to attach any intermediate brackets required (usually one every 1.0m) at the correct height to maintain the linear level.
Consideration needs to be made for the collected water - you can either let the down pipe expel onto the ground or more normally, collect in a suitable water butt for use on the garden at a later stage.
