  1. Hi Ron Do you have the Dodge events details ? I haven't seen any advertising to see where the venue might be. It might be a good distraction this weekend and chance to chat to others with a similar interest. I suspect other family members may have had communication with the Daimler Classic over the past 10 years on and off, for other details, will have to get reminded on how fruitful those explorations were... Wolf sounds like an interesting person to have a chat with, not many others here have that rebuild experience. Ah and thanks for the dissertation on the lead/tin solder properties.. After a month or so of absorbing information, we might strike a blow. Cheers Greg
  2. Hi RonB Yes I think there is one in the Benz collection, my brother visited a few years ago .. I have sent a request in via the contact form.. The vehicle was found in Oberon in the late 1960's by my uncle Graham Bliim (dec.), at a sawmill as a power source or yard truck that had been overgrown and neglected. However all or most of the mechanical were there, and so the restoration of motor, transmission, chassis and layout of trendy boat-tail bodywork. Just recently (June) we had it to the point of a fuel tank, and starter motor making the engine fire.. After a quick service of the old zentith updraught carb, the fireing turn into a running motor, so we took Mum for a drive around the paddock. The radiator was the weak link as it leaks badly, but fueled our enthusiasm to get the project more complete. The car is at Mums farm near Gosford, Im close to Lismore where we have the radiator, as we were going to visit Greg Stevens at Honeycomb Radiators (ftrs.com.au),but after a conversation he thought we may be best served by Replicore (NZ) as tubular V shapes were not his specialty. I only found this forum recently, and will post a couple of pics when I can find the collection... Regarding the harder and softer solder and or braze silver solder I would like to hear of any advice or opinions on the subject . As you can imagine we are not intending the car as a daily drive. I note that there is a modern trend in brazed copper/brass radiators with all sorts of advances ... Copper.org: Applications: Automotive - Brazed Copper/Brass Radiators Design Innovations Cheers
  3. Hi RonB Thanks for that advice, I will see if I can find the contact details for the archives and give the possibility that plans may be in existence! The ideas we are having (as they are cheap!) involve new metal in all the core tubes fins and upper and lower tank pans I have access to basic sheetmetal tools like folding brakes, punch press to slot the tank plates etc and like the idea of spending a few weeks fabricating.. Spending money last such a short time So its constructional hints Im most keen on. Would propose to use a harder silver solder or braze on the core.. and lower hardness/melting points for the tanks and fittings If fabrication was limited to a few months it would be time well spent, as the vehicle has been out of service for some decades now. As for the mortgage for a Replicore, it was cheap compared to a reply Ive had for a pebble beach quality rebuild in the States. Thanks for the hints Greg
  4. Hi there alsancle Very nice to hear from you, I am a new lurker here, so forgive my lack of depth of knowledge as to the similarity with those more fancy models!.. But yes it appears to be vertical tubes (49) that seem to be folded over and seam soldered on the back edge then inserted into slots on the bottom of the top tank and top to the bottom tank, with triangular foil (approx 10mm folds) fins. The tubes are around 70mm deep and perhaps a 1 or 2mm inner tube space and about 600mm tall. I have read on the Replicore site they use 0.15mm wall thickness tubes and 0.11 0.15 for the fins We have the basic practical experience in silver soldering and 50/50 soldering techniques, and is why we are contempating the roll your own solution.. And why we seek more knowledge from the ethernet. and those with pre war merc hands on practical experience. Would like to be able to create a new core before dismantling the whole radiator if possible. Thanks for the interest. Greg
  5. 1923 Benz GR5 restoration Hi Pre-War Benz enthusiasts... We have here a 1923 Benz being restored, and it is now at a mobile and running chassis engine transmission stage.. The next weak link in our chain of rebuilding this relic is the radiator, which we are examining to see the best rebuild path. Is there anyone out there that has any construction details for these V shape tube and fin cores ? Tube metal thickness ? fin metal thickness ? Source or materials.. I know of Replicore in New Zealand who will do a core and rebuild for us, but the price is a bit beyond our hillbilly budget. At this stage we are planning to rebuild a new core from scratch and get the tanks swapped over to the new core. If anyone has ever pulled one of these units apart and could shed light on how the core and tanks are joined and constructed, it may allow us to proceed to build the core with the original still in one piece. In Australia here we have limited options, and while we can find folks to put the tanks on new cores, not many are willing to build a core. Having the original radiator intact with a new replacement core beside it would increase our options in getting the rebuilt radiator back into the chassis, so we can drive around the paddock again. I will post a picture of our first drive in the bare chassis since 1940's for your amusement. The vehicle is not a concourse edition at this stage, but for the first time in decades it is mobile. Cheers Greg
