Large double ended wood screws
I need some LARGE wood dowel screws - the double ended wood
screws the small variety of which are often used to fix wooden knobs to doors. I'm joining 5"x5" timber baulks upright onto 10"x5" oak railway sleepers, so need perhaps 10mm or 12mm diameter and maybe 100 mm long. Google finds lots of tiny ones but no big 'uns.(well not quite true - I found a supplier who offers 1" x 8" screw dowels. I rang them to check that that was 1" diameter by 8" long which they confirmed, but when they arrived they were 1" long by No 8 !!!!!!!!! ) Anyone know of a supplier? AWEM |

AWEM If you only wanted one, I guess it might be practical to chop the head off a coach bolt and grind it down to give a 2nd pointy end. I guess you've got to find another way to connect them. NT |

You could try setting hex coach screw heads into the sleepers with resin, and using the other end to screw into the uprights. |

A lot easier to do it the other way round, screw in first, then resin the head(s). NT |

Just out of interest, how would you use the double headed screws? I've so far totally failed to see how you could use more than one per upright since so far as I can see you have to rotate the upright (or the sleeper!) in order in order to tighten it. (I ask in part 'cos the one time I did something similar I used dowel screws which were thread to take a nut - like http://www.screwfix.com/p/machine-th...ck-of-10/11850 - but of course that left the nuts exposed and visible.) -- Robin PM may be sent to rbw0{at}hotmail{dot}com |

AWEM How about some largish threaded rod (10-15mm). Most sheds stock it. Cut to length, drill a slightly undersized hole and put it 60-100mm into each side. Put the first end in buy using a couple of nuts and locking them up together, use a spanner to then screw into wood. In anything other than balsa wood it should hold quite well. |

Hole drilled in sleeper and the upright, screw inserted in holes, upright rotated by large custom made wooden spanner. Handrail will stop them rotating. AWEM |

AWEM how long are the 5"x5" timbers? I did something similar using studding. Set both ends in 2 part filler so the holes didn't have to be 100% accurate Good heavens this was a post I made YEARS ago. The solution that I adopted was to weld large coach coach screws into the centre of 100 mm plates which I bolted to the bridge oak sleepers (in rebates) I then screwed the handrail uprights onto the coach screws and installed the handrail. (This is curved bridge based on 10" x 6" RSJs that I had rolled to an arc). This worked splendidly until my builder took his 3 ton digger over it carrying a massive tree root ball of at least a ton. (Calculations for the bridge had been based on 2 ton max). The RSJs flexed a bit with the result that the coach bolts pulled loose in the end grain of the uprights and made the handrail wobbly. This I totally cured by welding up what were effectively long eyebolts, the threaded part of which went through the oak sleepers and were fixed with nuts and washers under the roadway, and the eye went flat against the upright through which I drilled a hole for a long bolt that picked up another such eyebolt on the other side. It is now massively rigid and grandchild proof :) Andrew (the original poster of the question yonks ago !!!!! ) |

Hi Andrew, Did you ever manage to find a solution to this problem? I have some broken fence posts (4" x 4") which I wish to repair. I was thinking of having some large double ended wood screws made from hexagonal bar. One end would have a standard "clockwise" thread whilst the other would have an "anticlockwise" thread. ( Like the thread on left hand bicycle pedals except these will be double pointed wood screws of course). This way, the screws can be tightened with a spanner on the hexagonal bar in the middle. Hence the posts can be repaired without having to dismantle the fence. I need four but it will cost less per unit if more are made. How many do you need? Does anyone else need some?

Maybe so, but perhaps he was attempting to save writing it all again. it
sounds a bit like those devices you get on boat rigging where you can tighten the wire up du to the threads being opposite handed in either end of a sleeve, then simply use a lock nut to secure them.
