TEMPLOT 3D PLUG TRACK - To get up to speed with this experimental project click here.   To watch an introductory video click here.   See the User Guide at Bexhill West.

  • The Plug Track functions are experimental and still being developed. Some of the earlier pages of this topic are now out-of-date.

    For an updated overview of this project see this topic.   For some practical modelling aspects of using Plug Track see Building 3D Track.

    The assumption is that you have your own machines on which to experiment, or helpful friends with machines. Please do not send Templot files to commercial laser cutting or 3D printing firms while this project is still experimental, because the results are unpredictable and possibly wasteful.

    Some pages of this and other topics include contributions from members who are creating and posting their own CAD designs for 3D printing and laser-cutting. Do not confuse them with Templot's own exported CAD files. All files derived from Templot are © Martin Wynne.

How to make a Turntable

Hi. I wish to build a sector plate turntable like Bembridge (I.O.W) but I do not know how to build this on templot. I have found it on you tube.

Hi Ray,

Bembridge is a turntable, not a sector plate.

The turntable ring is created as a dummy centre-line-only track template.

Here is an old video which might help:

To create the V-crossing you can now use the find intersection function. I will make a new video shortly.

cheers,

Martin.

Ray,

It's all in the video, that Martin has posted a link for.

If you still have problems, email me with the info and I'll sort it for you over the Xmas period.

Merry Christmas.

Hi Ray,

Here's a quick video clip showing how to make a circle:

https://flashbackconnect.com/Default.aspx?id=CPZtqGuhCyRHdv3p3_TXLw2

The video is for a radius of 160mm. i.e. a diameter of 320mm.

If you are modelling in 4mm/ft scale and want a 50ft turntable, the radius would be 25ft. So you would enter a radius of 25 x 4 = 100mm.

Sorry the video is scruffy. It's painful to use the computer at present.

cheers,

Martin.

The long hand version of why 25 foot equals 100mm in 4 mm scale
25 x 12 converts feet to inches, so 300 inches. Multiply by 25.4 to convert inches to mm in full size. So 7620mm divided by 76.2 (correct scale for 4mm) gives you the 100 mm scale size.
cheers
Phil
