Homemade Straining Posts

[TheRanger]

Have got quite a few very straight birchwood tree trunks from felled trees. 8”-12” diameter. How long would you expect these to last as straining posts? They’re much heavier than any bought in strainers we’ve had before, but untreated.

Not, 7-8 years i would have thought by how long it takes a windblown birch to rot away.

4 or five yrs at best better to let them dry and burn them in the Woodburner to save wasting your time at least.

Its not so much the thickness of the wood / material that matters , its the resistance of the material to wet and dry rot etc.

Stand the bases in a preservative (creosote?) for a week or two, and when they're knocked in, slope the top in necessary and put a cap on it to shed rainwater.

Dry them out, then soak in waste oil and creosote for 6 months. They'll then last longer than anything you can buy.
If they were stood in 6in mix as they dried out would they soak it up?
No need to treat the bottom 2 ft below ground level, just 1 ft below ground and all above.

If you put them in a steel tank . Put some creosote in and build a fire under it they will last 60 years , did a few thousand like that years gone by

Creosote ain’t what it used to be in the good old days. Like a lot of other thing sadly..

What have they removed from it that makes it less effective?

That seems to claim to be the original stuff, anyone used it?

Have got a tub of creosote that’s been lying on a shelf for 20 years, so will make a start with that and some waste oil.

Everything that made it work....

I think the creosote is probably ok, I suspect the quality of the timber is poor and the depth of treatment is definately cRap.
