That's really, really nice James, I must have missed seeing this over Christmas. Both the build and the weathering are excellent in my opinion! Did I hear you mention a TM.....any thoughts on a TK as well perhaps?:)

Cheers guys

I have all the blueprints for a TK, just got to find the time to get around to doing one!

Grabbing some time between uni work to get a craft knife out and do some proper old school scratch building, no lasers in sight! 

Having reviewed the Rolba R1200 I realised there where a number of design features I had overlooked in my initial attempt. Particularly around the cab lift mechanism. 

Therefore I've started again. 

r1200_01.thumb.jpg.1e7e97f02ba05a30b32459ef8a59357d.jpg

First up is the most complex part, the cutter head. This is constructed of four conical with eight 'knives' wrapping around the two drums. Required a lot of maths, first to determine the pattern to roll into the cone, there is a calculator online for this. They are roled from 0.25mm plasticard.

The second bit of maths is to calculate the radius of the cutting knifes to account for the shrinkage as they're stretched across the width of the drums. 32mm drum required a 36mm diameter knife.

The next bit of maths was to work out how the parallel linkage for the lifting head worked. The head can lift a meter higher, but the linkage allows the cab and drum to remain level through. A few pins and some cut outs of the blueprint and I eventually had it figured.

Every panel on this build seems almost pointlessly complex for what is a very boxy shape. Cab and all its many angles constructed and the parallel link arms fitted. These allow the cab to remain level as the cutter head is lifted and it was a relief to see the maths work as the mechanism functions perfectly.

Next to the mog for a size comparison

What's the Schmidt blower like James, keep fancying one for myself.

I was watching the recent agricultural adventure DVD from landtechnik videos, and thought Erntetechnik steinbergers, New Holland t8 was quite a monster chiped to 500hp

That certainly looks a beast Jack! 

The Schmidt is a nice model, metal making it relatively heavy. The cutter head could be a little more delicate but certainly far fancier than the Siku equivalent. Wide three point link though, had to bend them out on the deutz to get it to fit

This build had been on the cards for years, the Bedford TM was always parked at Glenshee Ski Centre when I was little and I've wanted to make it ever since. 

A few photos from the build. 

IMG_20220314_214411.thumb.jpg.ec59207988b6d518486231126b9aa7e1.jpg

I had built the cab a while ago so we pick up at the construction of the body. Laser cut acrylic to build up the repetitive drop side panels. 

IMG_20220316_064245.thumb.jpg.e0b6c07f51eab87238a1c0ff0370b94c.jpg

The Cuthbertson Snow Plough featured previously will be mounted on the front

A few final cab details,primer is used to give the various bits of card a monochrome colour to identify any hidden issues or likely spots paint won't adhere. 

IMG_20220317_223306.thumb.jpg.49fe28229175466fefd9a9e468a06ea8.jpg

Some filler primer builds everything up to give a nicer paint finish. 

IMG_20220407_202610.thumb.jpg.4acb3a151a00ab42687a2bf7ec1c504a.jpg

The chassis is again laser cut acrylic with some 3D printed axles. The wheels and tyres are also 3d printed.

IMG_20220409_124530.thumb.jpg.ec320ec7acaf11eb901e320941be61bf.jpg

A few other printed bits detail the chassis to the point I want it, fuel tank battery box etc. Much quicker than building with plastic card.

Paint and decals follow, a mixture of spray paint and hand brush to get the details. These days I do alot of painting in matt black because it adherse well to everything then just spray with gloss clear coat after for the shine. 

IMG_20220319_193727.thumb.jpg.4953617512d99dbd39c89e99ab8d6c0e.jpg

Up close of the wheels. The ability to rapidly create exact wheel types opens up an whole host of builds. 

IMG_20220319_215522.thumb.jpg.3bef775884de4241e2ce9be6d7e93b26.jpg

Coming together now.

Good old coffee stirrers for the deck, I've just finished the first 1000 bag of the pack of 3000 I bought in 2015.

IMG_20220409_161548.thumb.jpg.6fec6456b955a23e651752597043cb11.jpg

All starting to look the part now ready for final assembly.

Glazing, the bain of any model builders life. Actually very pleased how these went together. A good tight fit and just a fab of PVA to hold them in place. Normally side windows I cut oversize and glue to the back of the panel, here I've cut them to the size of the appature and the final effect is much better.

The finished article, I am very pleased with the final outcome here I have to say. It would have been nice to give the body more detail and a steering axle but I knew if I overcomplicated it I'd never find time to finish it.

Apologise, not the most Agricultural subject but don't you worry, a build thread coming soon that is more on topic.

Excellent model James very well put together, 3D printing is definitely the future for model making / building a little grasp of CAD and the World is your oyster, The things I have sketched up in recent months is just amazeing, On the subject of cab glazeing I'm just wondering how good smart phone screen protectors would be. I had an idea to try that a few months back but the .stl file I had for a DAF CF didn't download properly, ??

Regards

Joe.

I don't think screen protectors are the right material for the job I'm afraid Joe. They behave like glass when it comes to cutting and shaping, I think they'll just shatter/spider web at the first touch of a craft knife. I use 0.5mm clear plasticard, works well and comes with protective backing front and back so you don't scratch or mark it while cutting.

nice work james, not seen a tm in a while, pusser used to have a few but way more tk’s . have you got any further with the bedford tk you mentioned a while back ? 

as you say joe, the printer does make some stuff easy to do,got this sat waiting finishing at some point ,one of james ford d series kits.

Looking forward to seeing that finished Sean. Printed some 2d views of Thank you out but yet to get any further, simply not enough hours in the day at the moment! 

so am i james, but like you just not enough time of late to do much about it.

Another excellent build James. Love the look of them old TM's.

Regarding wheels/tyres - 3D seems to be coming into its own. Few years back - wheels seemed to be one of the big problems when scratch building - basically hope a donor model would have something close to what was required, or if you wanted a not so common size - get one of the specialists to produce one in alloy and rubber (which seemed to require a long wait, and could be relatively expensive).

Keep up the good work!

Very true John. Opens up a whole world of possibilities and one offs, just this weekend I've made two different wheels for a timber tractor project that I'd never have found something to match, within half a day I had a full set of both sat in front of me, marvellous.
