Hi Lance,
Thank you very much for measuring the hexagon.
Sorry I didn't explain very well what I meant by "inside tube" what I should have said is the inside diameter of the round portion of the tube inside the hexagon where the tube hasn't been flared on the ends. The section where I have put the red arrow on the drawing below if possible please.
Tony Betts has put the description of the method the guy used to build a radiator for his Brough, he used Brass tubes although most of the honeycomb radiators I have seen use copper tubes, do you happen to know whether your tubes are brass or copper ?
Hi Tony,
Thanks for posting the information on the guy building the Brough radiator. While there was a lot of effort building the core, I suspect there may have been the same or more building the header tanks and fittings. I'm certain he takes, and so he should, a lot of pride in the finished product.
I'm not suggesting I want to build a honeycomb core, I'm just trying to see if there is any confirmation of the books that say the early cars had tube honeycomb radiators and if so how long did that continue before it changed to film radiators.
However, for me, the enjoyment of old cars is learning new skills even if they were once commonplace. I had the chance to buy a set of whitemetal pouring moulds and a conrod boring machine. We have had a few false starts but we now are confident in the pouring of whitemetal bearings helped by a local forum member who spent a lot of his working life doing this type of work. I hope its a skill which can be spread to a number of other people in the A7 movement locally to keep the skill going and a service for members who need it for their cars.
