Are you going to re-engineer that connection also? Rich Thank you, Rich for your kind words. The nut at the bottom of the steering arm will be drilled and threaded on the inner side, to allow a bolt to join arm and the horizontal linkage that come to the wheel. This linkage isn't very realistic and is too short, so, it's possible that I would have to re-engineer it. Link to comment Share on other sites More sharing options...

Damned You're absolutely right, Dan It doesn't matter, because it's very easy to add it at this step of my building, ,and it will be done !

CrazyCrank Posted May 2, 2017 Author Share Posted May 2, 2017 (edited) Yeah, @PROPELLER Center hole drilled... I'll continue later my milling and drilling job on this steering arm and the linkage that connects to it.

CrazyCrank Posted May 6, 2017 Author Share Posted May 6, 2017 (edited) I'm not very productive actually, my few free time being monopolized by the logistics of my older son's wedding planning Little progress today though. The conical arm has been sanded and polished (It remained ugly marks of a very bad turning work). Now it's better and acceptable, if not satisfactory. This arm has been secured on the cylindrical bolted part, using silver soldering. The cylindrical part which sleeves on the steering shaft has been drilled 0.8 mm, then threaded M1 at its top. And through this hole, a 4 mm M1 bolt will take place and could be tighten on the shaft to secure the connection with the steering arm. At the bottom of the arm, in the "nut", an identical hole has been drilled and threaded and a 8 mm M1 threaded rod has been screwed and then soldered. This operation has created an axle which will allow to connect the horizontal linkage moving the wheels. Regarding this linkage, i'm going to scratchbuild a new one with brass rods and my lathe. The parts provided by Pocher are unrealistic, too thick and too short, and the real linkage is not horizontal but contains two sections: the rear one, which climb, and the front one, which is horizontal. That's all as for now Stay tuned if you like Edited May 7, 2017 by CrazyCrank 5 Link to comment Share on other sites More sharing options...

CrazyCrank Posted May 8, 2017 Author Share Posted May 8, 2017 (edited) Well...as told me another modeller: "Slow and steady wins the race" So, slowly, but surely, I continue the scratch building of my steering linkage. The Pocher parts of the linkage, compared with my reference photos, seem too thick: - 4 mm for the connector (with the steering arm) - 3 mm for the horizontal linkage wich join forward the connector on the right front wheel. So, according tho what I see on all my ref. photos, I've arbitrarily decided that: - the connectors will be 3.0 mm - the horizontal linkage will be 2.5 mm First, I'd have to learn to master lathe turning techniques with different tools, in order to have an accurate usage, and get a smooth surface finish... After several tries, I undertook to turn the first connector: - Starting form a 4.12 mm gauge brass rod, 25 mm lenght - Drilled it on the lathe 1.5 mm gauge over 5 mm - Reduced the thickness to 3.00 mm over 10 mm - And then, reduced diameter on the following 0.3 mm, to 3.5 mm - Next, reduced diameter to 3 mm on the following 0.6 mm - And last but not least, reduced diameter to 0.6 mm on the following 0.6 mm Later, I put the part in the dividing head of my miiling machine, placed vertically on the crossing table, in order to drill on it a 1 mm hole perpendicularly And I got this part: Compared with the Pocher's one: . This connector near the steering arm Both with a M1 brass bolt All parts connected Put in place on the chassis It remains to scratch built the front connector, using the same methods and measures, and the horizontal linkage Later, all this stuff will be nickel plated Stay tuned il you like, and thank you for watching.

CrazyCrank Posted May 29, 2017 Author Share Posted May 29, 2017 Very difficult to be everywhere ! Hereunder are the reasons of my great absence on the forum and lack of progress on my Bug's build ! My free time has been entirely monopolized since several weeks by my older son's wedding I cannot resist the pleasure to share with you my happyness and pride, and present you my best "reduced" model, Matthieu (32 years old, 6 feet 4 inchess, for 253.5 pounds), the groom, and his fiancée Mélanie (no measurements Gentlemen): And then two brothers together, Matthieu and Jérôme, my younger son, who lives in Montreal since 6 years: Champagne for everybody here 2 Link to comment Share on other sites More sharing options...

Codger Posted May 29, 2017 Share Posted May 29, 2017 A wonderful family to be proud of with a lovely new addition! Congratulations my friend, you have done well in life and these are your rewards. I would love to chauffeur them to the Rivera for their honeymoon in my Phantom II Sedanca but the hood panels are not yet complete. When you raise a glass, think of us here, filling the room and toasting with you. And when you awake and sober up, get back to this wonderful Bugatti! 2 Link to comment Share on other sites More sharing options...

Totally Mad Olivier Posted May 30, 2017 Share Posted May 30, 2017 Dear Thierry, congratulations for your son! You know I am me too running after time, that's why I can't take the time to look at other threads, yours in particular. But the few times I do, I am always very impressed by the quality of what you show. All the best Olivier Link to comment Share on other sites More sharing options...

Mine isn't ready to ride🙄 It's possible to rent an old Bugatti, but absolutely too much expansive. (http://www.classic-rent.fr/FR-location-bugatti-m28.html) I thought for a moment to do it, and finally abandonned this idea. Link to comment Share on other sites More sharing options...

CrazyCrank Posted July 10, 2017 Author Share Posted July 10, 2017 (edited) Hello Gentlemen...I'm back on the thread... And, inspired by Dan (PROPELLER), i've modified a part of my car, the tachymeter's bevel gear. Details of the "making of" later... Hereunder the achieved piece And at its place Thanks for watching Edited July 10, 2017 by CrazyCrank 3 Link to comment Share on other sites More sharing options...
CrazyCrank Posted July 10, 2017 Author Share Posted July 10, 2017 (edited) As promised, the "making of" of this tachymeter bevel gear.... The first try i'd built used styrene rod, and alu and brass micro-tubes. The system was represented but not very realistic.... While I was working on other parts of my car, I damaged this system and, strongly inspiring me with the oustanding work of @PROPELLER and with my reference photos, I've decided to re-build it. I don't know if it would have been possible to machine it in one part, because I'm not a metal worker, so, I've machined it in two principal parts. - the first one, which connect at the top of the gearing box with 3 bolts, has two shallow grooves - the second one is connected on the first one First part of the bevel gear: Take a 6 mm brass rod, and on your lathe, reduce its diameter to 5.2 mm Cut a 4 mm length cylinder, and then reduce the diameter to 2,5 mm, you'll get this Install the brass rod into the dividing head of your milling machine, this head placed horizontally on the crossing table and mill two grooves separated by 120° with a 3 mm diameter bit: Then, drill over the top of this rod three 0.8 mm holes, separated by 120°, and with an 60° offset with the grooves, you'll obtain this: Then, thread the 3 holes with a 1 mm bit, 2 mm depth And finally,screw 3 3 M1 bolts, 2 mm length in the holes, and you'll get that: Put this part in your lathe and cut it over the 2.5 mm , keeping 2 mm lenght on the 2.5 mm section Next, place your dividing head vertically on the crossing table of your milling machine, and, with a 3 mm bit, cut a groove on the lateral side of thie piece, and you'll obtain that: Next, the second part : Machined starting with a 5 mm brass rod, reduded to 3.8 mm, there is a 4 mm length 3.8mm part, and then, towards the front, a 2.2 mm section over 2.5 mm, and finally, a 1.2 mm section over 4 mm, this last section 0.8 mm drilled ont its center, and backwards there is a 2.5 mm section over 2 mm lenght. And you get this, the part on top right of this photo: Having two parts for one piece, you must merge these two parts: - First I glued in place the second part in the groove I'd made on the first one, using fast Cyanoacrylate - Then, I could take the two parts, correctly assembled, between the jaws of a clamp And finally, I could silver solder them, to get this piece: It requires a lot of sanding and polishing to be clear, but the result is there, after 10 hours of hard word Thanks for watching and hope you like it Edited July 10, 2017 by CrazyCrank 3 Link to comment Share on other sites More sharing options...
