Railroad Ties for Landscaping
Where can I find mitre angles for creating a circular border around
the base of trees? For example, what is the angle cut needed to create a 7 foot circle, an 8 foot, or 9 foot circle? Thanks. |

This isn't what you're asking, but aren't railroad ties treated with all sorts of nasty wood-preserving chemicals, chemicals that can leach into the ground water? Patrick |

Where can I find mitre angles for creating a circular border around the base of trees? For example, what is the angle cut needed to create a 7 foot circle, an 8 foot, or 9 foot circle? Per previous poster, depends on how many "sides" the circle will have. A method that seems like it should work is to remember that the number of degrees, cut at an angel, in the "n" sided circle must total 180 degrees. In other words, a four sided circle (grin) would have each cut made at 45 degrees (180 degrees divided by four). An eight sided circle would have 22.5 degree cuts, six sided circle 30 degrees. I'm not much of a Gardner nor mathematician, but I believe that should work. Old Chief Lynn |

Sounds more like like a polygon (or octagon) - Most certainly an over-engineered tree basin. Why not just lay out the ties and make the beveled cuts where and at the angles requiired to close the polygon? Olin |

I presume the lengths are diameters and you really want a circle and not an octogon which would be very easy. Does the inside have to be circular or just the outside? Are you a master craftsman with a heavy duty router and a router bit the length of the thickness of a railroad tie? The real question here is: How many pieces of wood are you prepared to cut? Dick |

Oh, Olin, are you trying to develop this promising thread into some kind of practical solution? Where's the sport in that? (grin) Old Chief Lynn |

The message [...] You'll never get rid of the creosote, and it's messy. I acquired some ties which had been removed from the railway at least 20 years earlier, and hadn't been treated since. As soon as hot sun shone on the wood, the creosote came to the surface..a nuisance if it gets onto hands or clothes (or carpets, via shoes and pets feet). Janet Janet Oh my, you do have a problem. Must have been fairly fresh ties when you got them. On the bridge ties that edge my driveway, the creosote doesn't bubble up, the surface is weathering away sl-o-o-o-o-wly, and moss is growing out of some of the cracks. I figure there's 20 years left in them. :-) Creosote does weather, you just have to be patient. The fact that it weathers so slowly indicates that its toxins are released very slowly also - slowly enough that they will degrade (oxidise, usually) before they accumulate. |

.. . The remaining chemicals are mainly copper sulfate and fungicides, neither of which are cause for alarm (unless you get down on your hands and knees and gnaw on the wood... :-o). Perhaps you should provide more information on the fungicides you're referring to, and which of them might or might not be safe near edible plants. The OP may or may not want to stick some chives or parsley or other stuff in the ground near the treated wood. Besides, there are worse sources of pollution in your neighbourhood, such as the car in your driveway or the power mower you use. Unless you're the kind of slug who lets his car ooze fluids for years on end without fixing it, you cannot compare engines to fungicides/pesticides in contact with the soil. |
I propose using only one piece of wood, cut to the circumference of
your circle. (I'm sure _someone, somewhere_ must sell 30-ft. railroad ties!) You can just use a 90-degree angle on both ends, and then run it through your railroad tie bender (available from your local home improvement store for a mere $499.99), and there you have it! ;) Seriously, I wouldn't be too concerned about an exact angle because the ties will probably shift over time and something will inevitably grow up through the cracks anyway! Not exactly like building a picture frame. OK, now everyone can flame me for my "rustic" approach. :) Gary |
