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?

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.

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).

An idiot boy question (again) from me. 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,

They need to be big and meaty as there will only be one up the centre
of each upright. Hole drilled in sleeper and the upright, screw
inserted in holes, upright rotated by large custom made wooden
spanner. Handrail will stop them rotating.

You can buy metal brackets to do this job. The screw will not be
strong enough, I think your posts. will split with any side loads.
Or cut mortices into the sleepers.

Have you tried cutting numerous mortises in 50 year old well seasoned

You could make pins from rebar and fix them with a foaming glue or resin.

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.

Never tried them in wood but two multi monti's welded together might
work.

You could use conventional coach screws, counter bored in from the back
of the sleepers.

When I needed to extend an Oak gate post, I made up a template and
drilled holes to take glued dowels.

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

Hi Andrew,

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.

Dowel screws. Or drill a hole in each wood end & epoxy threaded steel rod in - that way you can move it into correct position before it sets.

Screws don't hold well in end grain. How would you fill the gap that
would have to be left for the spanner?
