The result is, as can be expected from something made by your hand, beautiful and inspiring. Many thanks, @Roy vd M., for these nice words I hope it will be achieved correctly ant that it is finally, as beautiful as you can imagine Link to comment Share on other sites More sharing options...

CrazyCrank Posted March 3, 2017 Author Share Posted March 3, 2017 (edited) Waiting tomorrow to scratch build the connector for rear exhaust manifold, that join the principal exhaust tube, I've polished the heat shields of the exhaust manifolds. It remains to clear coat them, the fix them on the exhaust manifolds, once these one have been shortened a bit, to fit to the brass connectors Edited March 7, 2017 by CrazyCrank Link to comment Share on other sites More sharing options...
CrazyCrank Posted March 4, 2017 Author Share Posted March 4, 2017 (edited) Making of the exhaust manifold connections First the front one: 1/ Cuted 10 mm of the Pocher plastic exhaust...It's a preliminary cut, the final length has to be adjusted after fitting tries 2/ Scratch built with a wooden rod 6 mm a connector between the copper exhaust and the exhaust manifold 3/ Adjusted it in order to get a right angle between this wooden connector and the horizontal portion of the copper brass tube, glue with low two-components. 4/ Waiting a slow drying, that allow to adjust the position of the wooden piece, if necessary, I've scratched and tested fitting a brass sleeve, with 9 mm gauge brass tube 5/ Later, once having assembled these parts (after adjustments, priming and plainting), we'll get that: To be continued, stay tuned if you like, and thanks for watching Edited March 4, 2017 by CrazyCrank 2 Link to comment Share on other sites More sharing options...
silver911 Posted March 4, 2017 Share Posted March 4, 2017 Another little lesson in how to make something from what you have to hand....great stuff. Ron 2 Link to comment Share on other sites More sharing options...
CrazyCrank Posted March 4, 2017 Author Share Posted March 4, 2017 After dry tests, I've removed 2 mm more on the front exhaust manifold... And now, I have to do with that: Ir remains: - To cut the rear manifold to shorten it 12 mm. - To scratch build a new wooden connector - To cut and adjust correctly the second copper connector tube for this rear exhaust - To solder it on the principal exhaust tube - To solder this principal exhaust tube on the outer 12 mm connecting plate at the front of the muffler - To solder the rear exhaust tube on the outer 12 mm connecting plate at the back of the muffler - To unmount this asembly, prime aind paint it Alclad stainless steel, and satin varnish the whole system - Re-paint the exhaust manifolds - Fix the heat shields on them - Re-paint the left protective shield (with louvres) alu mat, because all my tests have produced numerous scratches - etc. To be continued, stay tuned if you like, and thanks for watching 4 Link to comment Share on other sites More sharing options...

CrazyCrank Posted March 5, 2017 Author Share Posted March 5, 2017 The second copper connector for rear exhaust manifold is on the bench: It's a right angle bended brass piece of 8 mm tube. Hereunder, it has been presented in its hole on the protection plate, and is of course too long. If must connect on the principal exhaust tube following a sharp angle, so a little cutting... And filing... Test fitting... Remained a lot of filing and sanding and many tries to do...to finally get that: [ I have to confess that I havn't (yet ?) soldered the 2 brass tubes; many reasons for that: - In fact, I tried to, but I failed, because the tools I have didn't allow to place the two parts fairly close together ! - And it was really a chance if I failed, because the exact location of the parts between them is very difficult to determine without having placed them at their final location on the chassis, and, of course, it would be impossible to solder them in place on the chassis, without ruining all the model ! So, I've decided to glue them on a bit more than half-circumference with slow epoxy glue, that allowed to adjust as often as necessary the respective position of each part, until it is perfect. And now, I have to let the set dry during 24-48 hours Later, I will soft-solder the non-glued half-circumference, if it is possible, or better , will achieve the gluing with epoxy-metal glue Then filing, sanding, to get a soldered appearance. To be continued.... Stay tuned if you like and thanks for watching 1 Link to comment Share on other sites More sharing options...

CrazyCrank Posted March 7, 2017 Author Share Posted March 7, 2017 (edited) Finally, the epoxy glue isn't strong enough, and i've disassembled the tubes and undertaken to solder them Before disassembling, I'd drawn on the principal tube, with a tracing point, the shape of the connection with the rear exhaust tube After cleaning, sanding, polishing dans degreasing, I've maintened the 2 tubes in due position with vise-grips, and begun to solder them together step by step. And after filing and sanding, before polishing, I've got that: The whole set of parts for the exhaust system So, no metal epoxy, only soldering And, to enjoy the work done, a little comparison, on the picture below, betwen what i've made, and Pocher system: To be continued.

CrazyCrank Posted March 8, 2017 Author Share Posted March 8, 2017 After having seen @PROPELLER's superb work with his muffler mounting brackets , I was a bit jealous (I apologize for that) and I've verified on my Ref photos (Thanks @Roy vd M.), and determined that the exhaust system on the T46 Bugatti is rather different than the T50's one... And the mounting of the mufflers too ! Reading the plans provided with the Pocher kit, the muffler is directly screwed on 2 cross members, without brackets ....BUT it's not realistic and impossible to get a strong assembly following this way So, I've scratch built two mounting brackets for the muffler. How was it in reality on the prototype ?..I don't know, and I confess I do not care ! Taking a 0.5 mm brass sheet and my milling machine, I've cutted 2 rectangular plates 12x20 mm. 2 grooves have been cutted 0.2 mm depth, perpendicularly to the plate's length, from 8 mm of each end (Sorry, I' ve forgotten taking pictures during these preliminary phases) And I've got, once folded the plates alongside the grooves, 2 squared-U shaped of 12 mm long and 8 mm height. Then, using the muffler as a template, I've drawn on each vertical side of the brackets, the rounded shape of the muffler. Then, it remained to eliminate the 2 half-moon brass part of each bracket with a grinding Dremel tool, and files. Next, I've cutted two 6x20 mm brass plates, and I've bended them on the muffler to get its exact shape And finally, I got that: The goal was: So the semi-lunar plates avec been silver-soldered on the brackets After sanding, I got that: Placed on the crossmembers And the muffler on the brackets The whole set of exhaust system It remains, concerning these two brackets, to drill and thread the holes that will allow tho bolt the brackets on the muffler, and on the crossmembers.....a pure joke Stay tuned if you like 3 Link to comment Share on other sites More sharing options...
sharknose156 Posted March 8, 2017 Share Posted March 8, 2017 Very well done Thierry, also the epoxy looks like a clean welding done by the master welders at Ettore's workshops. (is that white wine ? cheers... but careful when you sand and file, and the metal particles may fly into the glass ) 2 Link to comment Share on other sites More sharing options...
CrazyCrank Posted March 9, 2017 Author Share Posted March 9, 2017 Tonight, I've fixed the 2 mounting brackets on the muffler. Drilled 2 holes 0.8 mm on each bracket, on both ends of their semi-lunar sides, then threaded M1. Drilled 4 0.8 mm holes , arranged in twos, on the muffler, then threaded M1. And fixed the brackts with two M1 5 mm brass bolts. The fixation holes of the brackets for the crossmembers will be drilled later, when the adjustment of all the parts of the exhaust system have been done... One step after the other !

Roy vd M. Posted March 17, 2017 Share Posted March 17, 2017 Looks like a nice lathe set, congratulations. I think the PD230 is an excellent choice. Meanwhile you've been working very diligently, in my view. Now you're just polarizing Link to comment Share on other sites More sharing options...
