Totally Mad Olivier Posted October 6, 2017 Share Posted October 6, 2017 Very dear Harvey, as Hannes and CC, I have missed the infos about your health (I was so focused on the other thread!). Glad to see you feel OK now, take care of you. And congrats +++ for your great work done in such conditions!! All the best my friend Olivier 2 1 Link to comment Share on other sites More sharing options...
harveyb258 Posted October 6, 2017 Author Share Posted October 6, 2017 Thanks for your kind concerns chaps....very much appreciated! I have some issues that need addressing (in progress), but, at least, I'm now getting some quality time back at my bench, building an iconic car from ancient blueprints and photos ....by hand.....and supported by a gang of like-minded nutters............. best therapy going!!! Anybody who is passionate about scratchbuilding will connect with that! . Cheers, H 4 Link to comment Share on other sites More sharing options...
harveyb258 Posted October 8, 2017 Author Share Posted October 8, 2017 Good morning gentlemen! Work continues on the chassis. I made the under-floor brace from 0,5mm nickel sheet, then decided to add a flattened T-shaped piece on top. The rear floor-panel can then slot in and be secured by a couple of bolts on both legs...easy access for the mechanics! Next up was to make the cross-beam that will be part of the fuel-tank support. I used 3mm brass tube, 0,3mm brass sheet for the webbing and 0,5mm nickel sheet for the mounting plates...all soldered of course! And in place on the chassis... Well, that's all for now, folks!! I hope you enjoy! Cheers, H 5 1 Link to comment Share on other sites More sharing options...
harveyb258 Posted October 8, 2017 Author Share Posted October 8, 2017 Just another little teaser for you chaps. I decided to make (well, cut to shape) a couple of floor-panels from 0,3mm alu sheet to see how my creation worked out. I'm happy with the outcome....a slight tweek needed here and there, but no dramas! That's all for now, folks. Thanks for watching!

Hannes Posted October 8, 2017 Share Posted October 8, 2017 Great progress , dear Harvey ! I really like your brace-support crossbeam construction ! I´m not sure if this brace still was provided for the successor or if the mounting plates replaced this brace . Unfortunately we cannot see the construction on the sideview of drawing 2 . However , this combination looks very convincing for me ! Many greetings ! Hannes 1 Link to comment Share on other sites More sharing options...

harveyb258 Posted November 6, 2017 Author Share Posted November 6, 2017 Good afternoon chaps! Work on the chassis continues....with these... The horrible kit parts just had to go. I had previously turned the tapered pieces of the rear cross-member, so that was a good start. Next, I made the forms from some scrap MDF and glued to the cones with 2-part epoxy... After leaving overnight to fully cure they were set solid. I then set-about cladding the forms. The edges were made from thin steel (0,3mm)...epoxied in place, then initially 0,3mm steel on the faces, with the intention of soldering the parts together. I didn't like the outcome very much so then used 0,3mm alu instead on the faces....much better! I then spent about 6hrs making the 1mm(M0,6mm) bolts from steel rod. These were turned by hand with a pin-vice and a small file...rather tedious, but fun nontheless! Still have to make the nut and stud rivets for the underside, though ...and in place on the chassis... Next up will be to make a couple of L-section pieces which will serve as support beams/mount-points for the rear part of the fuel-tank and also diagonal bracing to keep the frame square and solid. Well, that's all for now ,folks. I hope you enjoy and thanks for watching! Cheers, H 5 Link to comment Share on other sites More sharing options...
Hannes Posted November 6, 2017 Share Posted November 6, 2017 Great work again , dear Harvey . Your hand -made bolts are very impressive as well . That´s real scratchbuild ! I will buy all bolts , nuts and washers in the german Knupfer shop . They also have a great variety of other useful items so have a look . I will translate if you wish of course . Very well done !

NickD Posted November 6, 2017 Share Posted November 6, 2017 Harvey, Impressive as always. With all that steel it's not going to be a flimsy thing. Glad to see your progress, particularly given the reference material we all know so well. Very convincing. Regards Nick 1 Link to comment Share on other sites More sharing options...

harveyb258 Posted November 9, 2017 Author Share Posted November 9, 2017 Thank you for your kind words, Sam! Ok then chaps, a small update in the proceedings for your perusal. The support beams were formed from 0,5mm nickel-silver. First, I annealed by heating with a torch until glowing red as this stuff is very hard, cut into strips with scissors and then bent in the vice with a small hammer. Once cut to size and shape, they were then soldered to the rear cross beam. A piece of 2,5mm square brass tube was then soldered in place to keep the structure nice and stiff. After this, I drilled the chassis legs and corresponding holes in the 2 pieces from the previous update and inserted M1 threaded bar, fixed in place with 2-part epoxy. Everything now slots together perfectly! That's all for now folks, I hope you enjoy!! Thanks for watching. Cheers, H 6 Link to comment Share on other sites More sharing options...

And when you're done it looks so neat and plausible that it hids the fact that almost all the details you are making have ben lost. Outstanding!

stevehnz Posted November 9, 2017 Share Posted November 9, 2017 Amazing modelling on display here, it's quite fascinating watching this progress. Something to keep an eye on for sure. Steve. 1 1 Link to comment Share on other sites More sharing options...
harveyb258 Posted November 9, 2017 Author Share Posted November 9, 2017 Thanks lads! I'm so glad you continue to enjoy! A BIG to you all! The next step will be to fabricate the support structure for the front of the fuel tank. Cheers, H 1 Link to comment Share on other sites More sharing options...
Codger Posted November 10, 2017 Share Posted November 10, 2017 Well Mr Harvey, you certainly win the Crazy Man of the Year Award for hand-whittling your own bolts - among all the other wizard things you've made here. MDF, brass, steel and Lord knows what else - ingenious use of materials. Inspiring work for all to enjoy. A sincere thanks for the clinic on how to do such things and the pleasure you give us as we follow along. You will have a spectacular model and most satisfying journey. 2 1 Link to comment Share on other sites More sharing options...

If my work serves to inspire just one person to take the plunge and try scratchbuilding anything, then I will be a happy chappy! Ok then...on to the fuel tank support (well, my interpretation from the drawings). For this, I used 2,5mm square brass tube from Albion Alloys..... Into the top of this, I cut a 0,5mm slot with a piece of hack-saw blade in a pin-vice... ....and bracing plates added... ....and soldered in place. I now have a question...There is a plate on both sides of the support structure ( merciless enlargements of drawing 2E -the blueprint-confirm this fact). However, on the plan view, the plates are drawn with alternating solid and broken lines (highlighted in orange). What would be the signification of this detail??? My own interpretation of this is plates with holes, to reduce weight and maintain rigidity. Can anyone shed any light on this for me? Your thoughts would be most welcome. I hope you enjoy! Thanks for watching, chaps. Cheers, H 4 Link to comment Share on other sites More sharing options...
Hannes Posted November 14, 2017 Share Posted November 14, 2017 A fixation point for the seat perhaps ? There is no obvious seat on the left side but according Salamano there was a second seat aboard " completely covered " I wonder where this seat was hidden and thought about the seat fairing as hiding place . But most likely it was hidden somewhere else . The CSI-rules for 1927 are a bit confusing and the " gap" on the left side could have been a possible fixation point for a riding mechanic´s seat . But this is pure speculation and I´m not sure about it . I quote : " Two seats remained mandatory in 2-seat cars but at the same time single-seater cars were allowed provided the seat ( region )had a minimum width of 80 cm and a minimum height of 25 cm " ( CSI-rules for GP races 1927 ) Many greetings !

sharknose156 Posted November 14, 2017 Share Posted November 14, 2017 Harvey what you are doing is just sublime ! metal scale modelling from scratch !! if it counts for anything, i align with Hannes's opinion. 1 1 Link to comment Share on other sites More sharing options...
harveyb258 Posted November 16, 2017 Author Share Posted November 16, 2017 I think I've sussed-out what the "holes" are, chaps. I knew I had seen markings like this before from viewing building plans throughout my career. Then I had the eureka moment....vents! Most probably louvres, or maybe slots. Cheers, H 1 Link to comment Share on other sites More sharing options...
Codger Posted November 16, 2017 Share Posted November 16, 2017 I go with your previous thought Mr H that those indicate holes - lightening holes in a stiffening brace. Why would louvers or vents be in a crossmember? 2 Link to comment Share on other sites More sharing options...
Hannes Posted November 17, 2017 Share Posted November 17, 2017 Drawing 2 is a plan for a successor version . We cannot see the big cramp including it´s U-profile outside of chassis and bottom sheet like on our 806 . We don´t know if the triangular reinforcement parts we can see on the plan view already existed in our car or if internal alterings replaced the big cramp under the bottom sheet . These "gaps " could have been smaller cramps as well possibly for holding parts together . Our 806 was too heavy and according Massimino the successor was supposed to be 40 ( ! ) kg lighter . That´s a lot and many people would be glad in our days to loose that amount of weight . Removing the big cramp could have been one of these weight-reducing measures . The fact we don´t see absolutely nothing on the side-view of drawing 2 could be an indication that the problem was not yet solved when it was drawn ( after the Monza race ) or the draughtsman forgot to represent it . Most likely drawing 2 was drawn on an opaque paper over an original plan of our car . The wrong drawn central fasteners for the front wheels are the result of an copying error imho .There may be more errors of this kind . We should stay sceptical ! Many greetings !
