PowerPlates for the upline!
More to follow
This is looking good. Keep it coming Ian. Great to see.
Couple of questions
Is that 2nd and 3rd Radii curves ?
Does the power track work ?
Looking forward to this thread, as the boss is leaning towards granting planning permission for the "cave" to become permanent - think its got more to do with being easier for her to make sure I'm behaving, and more difficult for me to ignore her
Hornby 3rd and 4th radius 'R609 & R8262'
Yes the powerplates work real well.
Did research and theres a guy if you google the corkscrew lines you can see his mahoosive helix!
More to follow soon,
Cor Ian that looks a complex build looking forward to the posts.
I can feel the sketch pad comming out
Looking good Ian, some impressive woodworking there, is it a kit of parts or have you designed your own?
Roundy roundy with a twist ! Very impressive helix. Looking forward to the follow on.
Its been designed by myself
I did a massive amount of research on the good old tinternet and there's a great blog called the 'CorkScrew Lines' took a great deal of inspiration from him.
The name came from the Octagon base that it was all designed upon, using the 3rd and 4th radius curves this gives the outside and inside base radii for the Octagon.
I will post some more photos of the calculations, later.
I made a master set of curves that I used to mark and then cut out each complete circle of parts (four sections in all).
More to follow,
This is the calculations for the OctoHelix,
Using the following tools to markout and cut each section;
Managed to markout 2 sections of the OctoHelix per sheet of ply.
Track was marked out onto the master sections and a 10mm dia. hole drilled to clear the 8mm dia allthread rod.
Fixing to the OctoHelix base was Large Penny Washer, standard M8 washer, standard nut and a NylocNut to stop everyhting coming updone.
The M8 allthread rising in their set locations and locked into position.
On the left of the photo is the feed from the 'Higgins' fiddle yard.
Joining the OctoHelix sections together.
Well thats the basics of the build along with the calculations etc.
The rise is 4 inches per turn, I use a steel rule to move at 12 O'clock 1 inch, 3 O'clock 2 inches, 6 O'clock 3 inches and finally 4 inches at 9 O'clock.
I used the DCC Concepts PowerBase on the upline only as I will be running GWR steam engines. I am trying to keep the gradient steady through out. I have also created a slight super elevation of 0.5% from outside to inside. So far the little 0-6-0 chuggs up no problem.
More to follow, but if you have any questuion then ask away.
great thread Ian, you have us engrossed now.
keep it coming as it happens kind sir
mmmm 4ft, you do realise the boss has just removed you from her christmas card list
