New Block thread on H.A.M.B.

[KR500]

Tod, Congrats on the endeavor. Few realize in this country the advances we have made in the manufacturing processes. Autocad rather than high school failing drafting students has made it possible to draw lines and circles all the same and legible. Solidworks for 3D capabilities. CNC, Turning centers, EDM, WEDM, robotic welding have all enhanced the ability to create product without all the huge runs of parts needednto make the stuff profitably. If my choice were between a new cast block and rebuilding an 80 year old casting, I'd choose new. I have been told that engine castings were at one time placed outdoors for a year for seasoning hoping to give the casting a chance for any stress problems. Is it still true? Good luck with your project and smooth sailing on any future challenges. In this country I don't know how we let so much of our guarded manufacturing knowledge sneak out, but globalization must have limitations.

Tod- This is a great project. Don't listen to the "nay sayers". Most of them form opinions because they didn't think of it themselves, nor have the knowledge or means to do it themselves. Please feel welcomed here and keep posted. Thanks again for helping advance the hobby.

I tried to PM a few of you but my messages were lost because it said I was not logged in. But I sure was logged in, to read a couple of PMs to me. So, I 'll have to try it again some time. I appreciate the "encouragement" on both forums, PMs, and emails. With the block sitting in one of my vertical CNCs being cut on you better believe nobody is going to dissuade me. I'll send pics to those of you who are discussing things with me privately.

I was wondering with a new raw casting, how do you decide what surface is the first to be machined to form the basis for all the rest of the machine work?

Tom,

I sent you a PM about that.

Tod, you are a positive influence to the Model A community. Good luck and looking forward to your progress.

There is a poll up on HAMB for this engine to see where he should start production.

as many have problems with cooling,will the alum block be an improvement on the original? if Tod's smart he will go back to the Hamb.

I still post on the HAM.

I congratulate Todd on this venture and wish him the best with it. I have been told that the best cast iron to use when making an engine block is an old engine block. They have been through the hot/cold cycle many times and that, I’m told causes the granular structure of the metal to change for the better. If all of that is true, there will be no shortage of scrap Model A blocks with a new purpose - feedstock for Todd’s new ones.
I’m no metallurgist and only have what I have been told to go on. The above may be all B S I have been told, hence this proviso but if true, don’t throw those old blocks away. Who knows, the numbers as well as the metal might be recycleable.
