This is how I did mine, length of wood tow blocks 1/2" difference in thickness, 12" apart (between the part of the block in contact with the rail) 1 in 24, though I tried to ensure the bubble was towards the thicker piece of wood if not central which would give a shallower gradient.

OK..
Practical question on this: - Well, maybe? :think:

Would it not be better to have the length of timber/blocks the other way up?
That way, if you are laying/checking across two blocks, any dip where the blocks join will be obvious as daylight under the length of timber. It the timber rocks (end-to-end) you have a hump.

This, of course assumes the spirit level is rigid! :eek::rofl:

No, because then you have issues.

If there is a dip in the track, then the ends of the long board would touch the rail, not measuring the angle over the 12", but the angle over the length of the board, which means recalculating the grade each time it is used.

If there was a hump in the track, the board would rock on the track and not give any consistent reading whatsoever as it rocked to and fro.

Only if the track is perfectly flat over the entire length of the board would you get a good reading that did not require recalculation.

Right confession time...

The jury is in and after careful consideration, it is confirmed I am an idiot, no surprise there then.

I have managed to make a basic error, and created a 1 in 24 incline, not the 1 in 48 I was planning on, no wonder the trains don't work.

...point proved with the 4 foot level, a 6 foot-ish piece of timber and a 1 inch improvised wedge-ish thingy...

IMG_20190517_191310.jpg


... or to put it bluntly that 9 foot straight drops 5 inches, yes I know that makes it 1 in 22, but it's not an exact measurement...

IMG_20190517_191449.jpg


...so now the sort it out prep work commences...

IMG_20190517_192113.jpg


...there are three plus points in all this negativity...

IMG_20190517_192347.jpg


...the first section is 1 in 48 ish, and confirms why the trains romped up it...

IMG_20190517_191411.jpg


...and the second is I found this guy, who resides in the vestibule end of one of the coaches he must have got ejected from the coach when it toppled yesterday.

Looks as if his reading material is one of "for dummies" books, probably "track laying".

...and, my spiral looks to be back on the cards, unless I cock that up as well.

I was thinking 4.2% grade pretty stiff...

My friends give me grief when I run 4-6 locos on the head end of a train, but mine is 3.4% for about 60 feet, so the whole train is on the grade at once also. Some people brag they have 4% or 6% grades, but often it's a short bit and they get a run at it. Also, often it is those people asking me where to buy new gearboxes! ;)

Well done Nod, at least now you have understood the error of your ways and know how to sort it!

Error of way now sort of sorted...

New gradient is a sort of 1 in 56 ish allowing for the overhang where the plank was placed...

IMG_20190519_151018.jpg


...Henge modification gives some idea of the gradient lost during reconstruction...

...minor filling and generally tidying up to do, but it will have to wait, other commitments this coming week, anyway it was constructed in haste, so it may well collapse yet, I don't care.

That will survive ok, at least you are on the route to what you want now.

Well after 9 months, what progress have I made, I don't hear you all ask.

To be quite honest, the railway has been left to slumber, to the point that serious consideration was given to flogging it all (With exception of one loco.) off.

Anyhow, today has seen some very minor progress, in the right direction.

Firstly the ejected passenger is now back home...

...secondly the second Crock, is now technically operational...

...if only it was that easy to get a driver into the cab...

20200224_145524.jpg


...thirdly, got some more of those Airfix Quick Build vehicles at Christmas, so...

20200224_151213.jpg


...we have sort of all gone peace, love and flower power here, mind you if I didn't use the stickers could get another pair, a plan is forming.

For good measure looks as if may be able to add to the collection as well later in the year.

Greg.

It varies between 1.7 and 2.0 %, it has never been tested with an actual train yet.

One thing I have decided though, once it is tested the curve at the end is going to be turned to face the other way, in effect going further up the garden.
To then double back on itself via a series of loops.
