That looks brilliant Zak, nice work. Really like the dug out mud effect around the corners

They look bob on Sean, nice bit of CAD work to make that loader too

Liking that Barry, what material is the trailer kit made from?

Some cracking buys Stan, the 220 Volvo is next on my list, they look excellent models but a hefty price tag.

Normally it would be possible to find the odd reason why Britains have done what they've done, utilising a popular casting, understanding there's a market beyond the UK buyer etc. but on this occasion it really does feel like they've made a huuuuuge mistake, I guess only time (and left over stock on shelves) will tell.

Hope you have a good few days James, young Sam Hodson did well doing little borough to Dorset in 15.45 on his 880 brown... He's a fair man like for tackling that run but he done a good bit for charity 👍
Yes he did, tractor did well too, he's now bought a Martin Three Wheel truck to get about on the showground, a barmy lad

The tri-axles are legal on the road up until the point they go over 18.3ton tare weight. So a tri-axle silage trailer probably sits around the 8-10ton mark in steel depending on build quality, possibly alittle less, this means that the most you can put in one and legally travel up the road is 8-10ton of material. You're very unlikely to be able to get a full load of anything around that weight in a body that size. Theoretically therefore these would only be used on farm travelling field to field, of course there are plenty that whole heartedly flaunt these rules, and that's who buy most of these trailers. Big market out in Oz and America for these bigger trailers too!

Thanks to everyone for the messages wishing me well, glad to say that I have made a full recovery.
Before that unfortunate incident, I did manage to get some photos of the steam engines whilst they were leaving the show ring and also some lined up beforehand. Looks like I might have caught a photo of @stabliofarmer without realising who you were

As Joe says the main frame work could definitely be 3D printed, you could also easily print the mesh as long as it was on a solid back with the mesh detail raised of it, makes painting a little trickier than if you used the AA mesh or similar but would do the job. I'm in the middle of a house move but when things settle down I can get back to you about making one?

Sounds like they can be a bit tricky to prise apart Paul, or this blog post certainly makes a meal of it https://code3landies.wordpress.com/2014/09/01/britains-series-3-full-restoration/
From memory I took one apart years ago and pretty sure I just attacked the domed rivet/pin/screw with a good sharp drill bit and popped the chassis off without any drama.

The finish of the castings look incredible, thanks for sharing

Thanks chaps, pleased with how it's gone so far

those resin printers do look good, especially for detailed parts. have you pondered figures from it yet.
I haven't looked at figures no. I'm sure there'll be a good range available to download. I'd love to have the time and finance to incvest in zbrush and learn how to sculpt in it but I think we're away off that!

The cab construction starting
Some more work with the trenching gear
Working on the hydraulic rams that support everything. These are left over bits of telescopic aerial that I supply in my kits, as the copper collets go in the kit rams I have managed to keep some resistance between the two tubes by pinching the end of the inner tube to create resistance against the outer tubes inner wall. This has worked well and everything is stiff enough to hold itself up/down.
I am happy how things are progressing and with most of the rams out of the way I will hopefully get moving again having stalled for a while.
Thanks for looking so far!

With the body work well progressed focus had to turn to the daunting task of the trenching arm/head. I started with the pivot/mount point and then just freeballed from their to see what worked, the photos hopefully show how its progressed.
All done under the watchful eye of the forewoman Kipper the Cat who loves to sit and watch progress wrapped around my shoulders.

With the track carriage sorted attention turns to just how to build the rest of this baffling looking machine. I decided that the big boxy body was probably the best starting point.
The two sides are cut based on the drawing and some profile details added
The side lockers have a tapered shape are built by creating the front and back, spacing them apart and then adding the tapered sides.
The body work continues to be built up to create the main shape and chassis. These parts could be 3D printed but I enjoy building with the craft knife much more these days. i spend my day drawing on the computer so its nice to get home and make something phyically.

I've hinted at this build in the workshop topic but we're getting far enough through to warrant a topic now. The Mastenbroek 20/15 is one of the comanies medium size trenching machines popular with UK land drainage contractors. I've fancied building one for a while and while discussing possible dissertation topics with the company MD last year I managed to get some plans that would enable a model build. I had been hoping to make something similar to the Heath bale chasers where there is a more complex kit that could be offered as a finished model or self build kit but at the moment time doesn't allow and a single old school scratch build for myself will suffice. I am using some 3D printing but mostly it is good old fashioned styrene and craftknife.
The first challenge of the build was going to be tracks. It is likely something like the Ros Hitachi track base would be the right sort of size but it just wouldn't have looked right to me and so I turned to 3D printing to create the undercarriage.
Some CAD drawings of various track parts.
The 3D printed tracks, each track link is individual allowing the carriage to drive like a real track.

A splash of paint, some pins, rubber and decals and a finished model appears ready for the instruction manual.
The kit version lacks a couple of bits of detail that the scratch built version has but this was necessary to make an economically manufacturable kit. I'm quite pleased with the final outcome and plenty of kits have set off into Scandinavia, the machines native home.
Thanks for looking, I hope its been of interest!

The work can now leave the computer and begin to become physical.
I am using an Elegoo Mars Pro 2 printer complete with their Mecury cleaning station. Theres is lots online for those interested in the exactities of how it works but basically the printer works as follows:
- A vat of UV curing resin is suspended over a horizontal smartphone screen
- A build plate is lowered into the vat until it is 0.1mm above the smartphone screen.
- The screen shows a 1:1 scale photo of a spliced layer, the light from the screen curing the resin in the shape projected
- The cured resin, now stuck to the build plate, is lifted 0.1mm and the next photo shown
- This process repeats until the whole model is printed
- The print must be cleaned of excess resin using 100% proof alcohol cleaner
- The print must then be further cured to become stable using a strong UV light (basically a mini sunbed)
- The final print can be cleaned up with any supports removed
The printer showing the vat and the build plate submerged in the vat
The screen on the front shows the spliced image being projected on the smartphone screen at the time. You can see the build has just started (1%) and the expected time to print all 634 layers is 1hr 44min (actually ends up about 2.5hrs).
When finished the build plate lifts to reveal the printed part (successful or unsuccessful).
This view hopefully highlights how the spliced model on the computer lines up with what is printed.
The parts are then put in the Mercury clean and cure station.
This is the cleaned parts ready to take off the build plate and have 5 minutes in the tanning salon.
Once cured the parts are test fitted and any adjustments made in the computer and new parts printed ready to cast from.

These are getting very impressive now John, very little to suggest that those are scratch built, you'd easily think they are off the shelf from a big manufacture
