DavidJH Posted December 21, 2017 Share Posted December 21, 2017 Hi Stefan, Have you tried boiling water? Parts might be too big for this, but if you can cover it in boiling water and then get a weight on to flatten it, then hit it with cold water it might work? Cheers, David 1 Link to comment Share on other sites More sharing options...

Soeren Posted September 27, 2018 Share Posted September 27, 2018 Very nice to see you back and modelling. By the way - where do you source your hex bolts? 1 Link to comment Share on other sites More sharing options...

See pm The rivet party has begun... sorting these 26 packages already took some time😂 After counting 2600+, I figured that there are too few 1.2mm bolts. Need to order more🤦🏻♂️ And many small ines are not be needed in vast numbers. I had two beers while sorting and preparing it all yesterday night. /Stef 2 Link to comment Share on other sites More sharing options...
Soeren Posted October 26, 2018 Share Posted October 26, 2018 That is quite a lot. Did I forget to react to your pm? Sorry for that. I always have difficulties to visualise the size of such pieces when identifying the need and decide which ones to get. Maybe just order the whole offering avaliable . 1 Link to comment Share on other sites More sharing options...
Blaubar Posted October 26, 2018 Author Share Posted October 26, 2018 got the details and in that case know which ones to use😬 But as it's all Russian, at first I had it wrong^^ just not good enough with it 1 Link to comment Share on other sites More sharing options...

Jor-el Posted November 1, 2018 Share Posted November 1, 2018 Greetings, masterful work, IMHO. I am a live steamer, I work in 1/8th scale. I own an Allen 2-6-0 Mogul in that scale. I must say the level of detail which you have achieved is equal to or greater than many I have seen at Live Steam events. Talk about a "river counter"LOL. I would like to ask a question about the BR-52. Did all examples produced have equalized suspension? In other words, were all prototypes sprung the same way? I ask because I have a Tank Workshop version of this Loco and the instructions say to mount the springs directly to the frame below the journal boxes. No provision for equalization! Seems wrong to me. Thank you for any help in this matter, and for showing us how to build a "Real" BR-52. Carl 1 1 Link to comment Share on other sites More sharing options...
Blaubar Posted November 1, 2018 Author Share Posted November 1, 2018 Rich, he is for sure, nice and friendly guy! I can highly recommend his stuff. Hi Carl, Yes and now. I will prepare a diagram to explain n show u later tonight. 1 Link to comment Share on other sites More sharing options...
Blaubar Posted November 1, 2018 Author Share Posted November 1, 2018 (edited) Carl, as to my knowledge and research and all photos I have seen, all 52s were equalized (underhung spring equalized arrangement to be precise). Other than the BR50, the 52s did not have "Stellkeile" within the journal box and the -> these guys here: (Note that the 50 only had one "Stellkeil" and an equalization bar on the other side (slider? see second photo), therefore I changed the diagram a bit. The spring system was kind of like this, so short bearings were holding the spring system below the journal box... For all who have no clue what this is about... (here however shown with a normal (not underhung) equalization system. These are the dynamics of equalizing the pressure and force among all axles once running on non-flat tracks and so forth... Non equalized, it would look like this: Note that all wheels are not connected to one another but only to the frame and thus shock absorption is only done via one axle, increasing wear and tear and the non-well being of the crew. Btw Carl, here is the mounting of a bar frame version in Sinsheim, i.e a very early BR52, one of the first few hundred or so. If you look around in my alumb, I bet there are more pictures showing it in a better way. Here from inside the frame... A plate frame mounting is a bit different, as the frame was thinner and needed more strenghtening and as such different journal boxes... But I guess you know. And here the respective frame mounting of the spring link to the fixed frame bracket... And here an official drawing of a plate frame 52: Maybe it got you "confused" as there is an equalization break between the 3rd and 4th axle from the rear and as such there is no equalizer there and a direct mounting to the frame as you mentioned? I hope this helps and solves the mystery? Cheers, Stefan Edited November 1, 2018 by Blaubar Link to comment Share on other sites More sharing options...

Jor-el Posted November 2, 2018 Share Posted November 2, 2018 First, WOW! I never thought you'd go to so much trouble and I can't thank you enough. Second, my confusion came from the Tank Workshop's instructions about spring install. They also state the journals are to be left free to move, held in p!ace by a spacer tube. The entire assembly didn't match any references. Third, I have no online footprint, as such, no links, etc. But again, thank you for your help. 1 Link to comment Share on other sites More sharing options...
Blaubar Posted November 2, 2018 Author Share Posted November 2, 2018 Carl, they are indeed allowed to move up and down a few cm... The Trumpeter kit shows none of this as it is one mould... but in theory there is space around the box (top/bottom). The arrows I painted are far too big, but just showing where motion would take place (directionally). What is often mistaken that the journal box and the cutouts for the axles are carrying the weight, this is not true as the whole weight is carried by the brackets (attached to the springs). Zero weight is carried by the frame above the axles, it would shatter as it is too thin (plate frame). Again, on a diagram and in the real world, they look like this: Sorry for all this technical stuff. Trying to get some modelling done later tonight^^. /Stefan Link to comment Share on other sites More sharing options...
Jor-el Posted November 3, 2018 Share Posted November 3, 2018 Stefan, let me say I am not sorry for "all this technical stuff" as it has confirmed for me what I must do to make the Tank Workshop kit at least look correct. I feel that a lot of patience and some scratch building will do so. So again let me express my gratitude for taking time from your busy day and providing such detailed explanation.

Blaubar Posted November 5, 2018 Author Share Posted November 5, 2018 Good evening, finally some modelling The newest design of the sidewalk support beams, now accounting for the asymmetry but the two big holes (saving weight and material) in the middle are missing. They will require final smoothing and a few more runs with the sandpaper... In the meanwhile I worked on the trucks that will go to the dio as well... I added some canvas for structure and my grandpa had one of these at his house which they used in their 4500S to stay warmer (mobile 88 Flak-battery in the East) Added the same to the 4500A truck cabin. Now I am off to business in Berlin and on Wednesday a special visit to the BR 52 6666 in Schöneweide where I will inspect the tender and some interiors of the locomotive . This is the one: * Prost, Stefan Sources: * bahnstatistik.de 1 Link to comment Share on other sites More sharing options...

Blaubar Posted November 5, 2018 Author Share Posted November 5, 2018 Haha, I screwed up my floor tiles just now... broke the last one while installing it and now I need to buy another pack of 25 That sucks. At least I advanced with the newest plastic parts The one arm of the upmost one needs minor trimming towards the top and all more detailed smoothing. <- trying to screw up soon 😉 Cant wait to climb on top of and below the real one on Wednesday... olé Prost, happy modelling to you. 1 Link to comment Share on other sites More sharing options...

Blaubar Posted November 15, 2018 Author Share Posted November 15, 2018 (edited) Carl, you are welcome and it was fun, except for the pair of jeans that got soaked in couplings' fat-> garbage now ^^. @Soeren, I finished building the rig (so that I can drill both sides at once and in the same manner). So any of these days I will finally begin this mayhem. I am a sloth, sorry /Stef Edited November 15, 2018 by Blaubar Link to comment Share on other sites More sharing options...
Blaubar Posted November 16, 2018 Author Share Posted November 16, 2018 @Soeren Here we go... Screwing up has begun^^. Had to delve through all the materials to see which ones go where, this is quite a mess. Will see how many I'll add today. I placed 3 in the holes to show you Have a good evening in the mancave. /Stefan Link to comment Share on other sites More sharing options...
