    Close up photos are always cruel no matter how neat the build.

    We have been isolating since the middle of last week, the boss tested positive as did my daughter, remarkably I'm clear as is our grand daughter so guess who's running about for two households and doing delivers and pick ups from the child minder. On the plus side it's given me plenty of time to tinker about with the brake van etc.

    I've been thinking and having a detailed look at the wagon and decided I have taken the test build far enough. It's helped correct a number of things mainly items which will help further builds which is good. Also I am not happy with the handrails, the verticals need to be 2mm off the body sides not 1mm and I am not happy with the the horizontal handrails. So I am printing a revised body and starting again, also although I didn't plan to do so, I will also be printing the alternate side body and building the two in parallel.

    What's outstanding is a way of fitting the lower footboard supports and drawing some 3' 1" clasp brakes (yep this beast used standard wagon wheels not 3' 7" wheels).

    I have designed a jig to help bend the supports and a second to help get the supports and lower footboard square to each other, these are printing now and will be initially used on the test wagon.

    I haven't even though about the clasp brakes yet although I have a design for 3' 7" wheels which can probably adapted. First print is due to be ready around 1 o' clock today so I have a spare morning.

    Isn't it nice to have a nice day. Two bodies the standard body and the alternate body successfully printed.
    My delivery of 7mm wire arrived nice and early, so I have got the standard body to this state it looks much better with a 2mm separation and .7mm rather than the spindly .5mm wire:

    I even have a plan to make sure the horizontal handrails are horizontal (if it works). The alternate body is curing as I type this. The plan is to bring both models up to the position the test body was abandoned and then start experimenting with the supports and lower footboard. I finally feel things are coming together so much I might start disassembling the Mono X tomorrow.

    I've also been fiddling with the bending jigs for the lower footboards so in sequence

    The jig:

    The first test support:

    IMG_1341.jpg

    Four supports slot into the assembly jig and the footboard is glued upside down to the exposed piece of wire - well that's the theory, time will tell.

    The new way of fitting the horizontal handrails seems to work. Obviously the section across the door needs cropping and the ends dressing. Now one works on to another!

    Paul since you like cruelty I got as close as I could to the soldered joints.

    Jigs don't half make life easier :handshake:

    Hopefully I can clear the bench and work on the K1 cattle wagon, Transfers on order, so you never know .......

    Tight fisted Yorkshireman here, would never have wasted that bit of rod across the doorway. Instead I would have wasted hours making each piece fit:headbanger:

    I'm equally tight fisted, the sections chopped away have been use for the supports for the upper steps and salted away to be used for things like horse loops and basically anything that need a very short section of wire. The 5mm wire used on the test build has equally been unsolder and salted away.

    I have been fiddling about with the lower step supports and think I can utilise the existing drilled holes rather than gluing behind the w irons, it just needs some care or another bending jig and fitting, effectively it means fitting the footboards before the axlebox assemblies, but more later when I have proved the theory works.

    Lower Footboards

    Plan one was to fit the supports behind the solebar/axlebox so I bend up four supports using the jig:

    IMG_1348[9681].jpg

    The plan then was to use an assembly jig to correctly position the supports and allow the footboard to be glued to it after threading the supports around the springs.

    IMG_1349[9683].jpg

    But after fiddling about a bit I realised I could use the original holes cut through the solebar and fit the axlebox assemblies after the foot boards. After a bit of unbending are re-bending this is the result. The axlebox is just blue tacked behind the solebar:

    IMG_1350.jpg

    So the support jig needs amending to get the correct horizontal distance and a new assembly jig will be needed. There's a 4 hours print of a roof churning away so the new jigs will have to wait till later today. But all up its a much easier way of getting the supports correctly positioned, so I reckon its another win.

    The revamped bending jig and new support jigs are printed washed and cured, so I couldn't resist a quick play to see if everything fits and makes sense.

    Looking from below, pic 1, the 4 supports are sitting vertically upward in the pre-cut holes. Pic 2 the alignment jig ensures all 4 footboard supports are aligned parallel to each other. It works, so tomorrow I am going to glue it all in place and fit the foot boards. Assuming all is well just 12 more supports to bend (Rob remember those off-cuts!) up and 3 more footboards to fit. Fingers cross next 3' 1" clasp brakes.

    I am trying to work out how the footboards fit, made harder because the photo is of it, upside down.

    Ahh, that's better.:p

    IMG_1358.jpg

    I assume that the part in situ is the upstand for the footboard and then the actual 'step' will sit on top of those exposed pins?

    .Got it in one the part threaded through the 4 supports is only there to ensure they are all square and correctly spaced. When the supports are glued in place, it comes off and the footstep drops on top of the 4 horizontals. I'm just doing the opposite side so will do some pic's when they are done.

    Paul,

    Yes you should, can I apply the head banging to you!

    Have you ever seen anything as bizarre as this, I'm flummox.

    Trying to export an .stl of this simple jig, and there are definitely no other bodies visible.

    2022-07-02.png

    It exports without any problems but when viewed in 3D builder (or chitu) this is the .stl:

    2022-07-02 (2).png

    This isn't an isolated incident I have tried any number of exports and they all have the van end appearing in the .stl.
    I repeated the excersie in a different project and the foreign body doesn't get generated, so it's something in the project.

    Have you checked that you only have a single body in the project? - sorry for potentially asking the obvious but sometimes we overlook the simple things.

    Yep checked multiple times. I think it could be related to problems with Fusion 360 earlier today, so I have reverted to an older version and am experimenting to see if the same happens. More later,

    Frustration and switching on a lightbulb!

    I still haven't resolved the problem from post 155 above so if anyone has any ideas or suggestions I'm open to anu ideas.

    Back with the V1/2 build, footboards in place and hopelessly wrong, the vertical post should run down to outside of the solebar and clearly doesn't. Is 'mybad' still a current slang phrase for good and what's the reverse - my hopeless maths.

    IMG_1365.jpg

    Strangely I had thought about this problem when designing the V1/1 and came up with a solution which I obviously failed to retro apply to the V1/2.
    Top the support cuts applied to the V1/1 which means the support clears the spring assembly, below the same on the V1/2 which is what is causing all the problems.
    It will be fixed for Rob's prints!

    Such is life!

    And there's more woe

    First the good new one of the sigle shoes is perfect, so good it's at the back of the photo


    Unfortunately the one at the front the bar is too short

    Here is the old one that with a wee bit of fettling fits and the new one just behind it


    Will take pics of the twin shoe, once the glue has set, I broke one shoe off as I removed it from the bubble wrap :facepalm:

    Looks like you shortend the first pary by 4mm rather than 0.4 to give clearence.

    The originals will work fine as it allows for adjustment if the W irons are not quite in the right location.

    Will post up the twin shoes shortly. Getting time as SWMBO is doing outsourced seated excercise - she sits down and watches the tennis player run around seemingly its very tiring .....:avatar:

    I've just been watching outsourced cycling, just the last 20k of a 200k day.
