Rail filing jigs - 3D printed

These are super jigs and so easy to use.

Could I be so rude as to suggest a slight modification, how about having a second groove on the opposite face for an appropriate switch size, all that is required is a slot at the correct shallower angle, which will run on the inside

eg for a 1-5 either an A or as Martin likes a GWR 9' switch. on a 1-7 a B switch.

@Hayfield

Hi John,

You are not being rude! Making suggestions is what Templot Club is here for. :)

Sure, I intend to do jigs for all crossing angles, and for blade planing, and bending jigs for knuckles, sets, check rail ends, etc.

What I'm hoping is that for any template on the screen, you can click a button and get all the jigs needed to build it.

The snag is that it all takes so much time to do. There is a limit to how much time I can spend at the computer -- some days now my 73-year-old brain runs out of steam after a few hours. At present lots of folks are waiting for the special switch and crossing chairs for Plug Track. Especially now we have a cheap FDM printer which anyone can use to print the timbering bases.

I did the 1:5 filing jig purely as a trial to see if the idea of a plastic filing jig would work. It wasn't intended to be the final design, it needs to be smaller so that it can fit on the little 3D printer. I will do another one soon.

In the meantime of course, anyone with an FDM printer could create and post their own designs, the jigs don't have to come from Templot.

cheers,

Martin.

Just a thought for Martin. I have printed out the filing jig and put together. May it be possible in future jigs if on one side there could be say two locating pegs with corresponding location holes on the other side.
@KHC1

Hi Keith,

Your jig looks good. :) Thanks for posting the pic.

The problem with locating pegs and slots is that they are useless if not very accurate. But FDM printers vary. It would likely be necessary to first make a test print on the printer and adjust the settings to get a precise fit.

For the trial jig I opted for a design using a bash fit on an M6 roofing bolt in a square hole as the means of location. A bash fit is much more forgiving of size variations and printing tolerances.

Unfortunately as it worked out the fit on the bolt is a bit loose, and could usefully be tightened up in the next program update. M6 bolts also vary of course.

Also it is convenient to use the same design for the top and bottom of the jig. It just needs to be mirrored in Templot or in the slicer to make the opposite half. With pegs and slots it would need two separate designs (which could possibly both be printed at the same time).

cheers,

Martin.

Keith,
You need some wing nuts rather than simple nuts so you can just tighten them with the fingers. A coach bolt with a squared shoulder under the head that seated in the back of the jig would be nice too.

Great job though.

Rob I totally agree but i went for speed and used what i had to hand. Just need to get some rail to practice on especially as i am useless at soldering. But the first new year resolution is to build turnouts so i must buckle down......

Keith,
Clean parts, plenty of flux, the right solder and make sure the joint doesn't move until it is cooled sufficiently - get those right and you can't go wrong with soldering. Practice makes perfect........

My simple 3D printed bending jig as well. Measures about 40mm x 16mm x 8mm. I already have two printed out.

Just returning to this topic in light of today's news:

https://85a.uk/templot/club/index.php?threads/new-machined-rail-components-from-finetrax.527/

If you have an FDM printer you can save a lot of money!

index.php


Admittedly I have done only the 1:5 vee rails so far. I will get some more angles done soon. Unless someone else gets there first of course. STL files welcome here. :)

cheers,

Martin.

I’d gladly pay someone else to do the donkey work with vees and blades - I hate the filing part!!

I want to come up with jigs for some more angles :D Just need to find the time!

The jigs take seconds to file
It’s not the time, it’s the doing! I really hate filing, which I suspect stems from metalwork at school where a task was to file a perfect cube out of a lump of mild steel, probably with blunt files. My cuboid was getting smaller and smaller and I don’t think ever was a respectable cube. I did manage to get a grade B at the O-level though so I must have got something right!

So I spent a little time today and attempted my own jig based directly off @Martin Wynne's design, .STL attached.
I will get it printed on Monday and attempt with the bullhead I have on hand and compare it to a template I already have printed.
I did 1:5 and 1:6 but if the test print is successful I will make one for each crossing angle separately (Left and Right sides)
Likely needs a few revisions but for an hour or so I'm quite happy.

I can easily make this a lot shorter and for single v crossing angles :)
Opinions and changes are welcome! This was done in TinkerCad so I can happily share a link to the design if others want to try changes for themselves.

Paul,

I'm with you, when it comes to filing largish items. When I was an apprentice boilermaker, we had two 3 inch square blocks of 1/2 inch thick pieces of steel, the test was to produce a "T" and "U" the upright of the "T" had to fit into the jaws of the "U", I have hated filing ever since, but I don't mind filing up 'Vee's' or switch blades, possibly because there's a lot less material to remove and if you get it wrong, it's not too much trouble, to have another go.

Hi, so first few prints didn't come out great but I have refined the design and will pick it up during next week for testing :) It's alot more compact than previous attempts.
Originally I tried to make 2 different v-crossing angles on the same block but opted for individual in the end.

Update to follow

James

Hi,
I am new to all of this having joined the Scalefour society at Wells this year. I am building my first straight track whilst looking forward to the day I have enough practice to build a turn out. I came across the thread then downloaded and printed the first jig. Could you also send me the Tinkercad link please? I will look out for your update.

Hi Martyn,

Welcome to Templot Club. :)

Templot can generate STL files for filing jigs directly. Or at least it will be able to, when I have done a bit more work on it. At present it can do 1:5 jigs only. You can find them by ticking this box in the bottom left corner of the DXF dialog:

filing_jig_5.png


which over-rides everything else on this dialog.

I have done all that for you, and here is the STL attached.

It is intended for FDM (filament) printing in toughened PLA (I use eSun PLA+) -- I doubt a home resin print would be tough enough to work as a filing jig.

cheers,

Martin.

Hi Martyn,
Please find the link below to the crude 1:6 v-crossing jig I designed. It's very basic and still in its testing phase.
https://www.tinkercad.com/things/1MJwRrXxILB
I will provide updates here or in a separate thread once I have better-designed jigs. The home is to have the base design tested and printer by end of Oct so I can create those for other angles. Once done I will release the plans to Templot users :)
Cheers,

James
