Could someone post the actual link to the SOOC site???

Thanks,

Now you want one, dont ya Charlie?!

[Powderman]

Is there anything happening at that site? When you go to Classifieds there is only 1 for sale and no want ads. And no wa to post one without contacting them.

Stev-o,

Might be.   
Once I finish the K6 & then the GL1000 and if I ever find a 550 with an 8/75 manufacture date, a Sandcast would make a good addition to a tiny collection.     

Thanks for the Link!!!!!!

And the History is actually quite amazing and interesting. 
TO think that all of us here are part of that continuing history is even more amazing.
There is so much to learn that many of us never knew about these amazing Old Ladies.
I just hope that those that follow us can benefit from all the knowledge collected and keep it going into the future.

Reading info over there and found this tidbit. Does anyone else see the discrepancy I do?

The Red Pre-Production machine went back to the Honda Training Center, sometime early 1970, where the engine would be removed from the frame every morning, the engine would then be dismantled for training purposes nearly every day for about the next three years.  By the end of the day, the engine would be re-assembled and re-installed into its frame.  Then, Bob Jameson would ride it home every night and ride it to work every morning.  Mark McGrew learned the technical details of CB750 engine repair on the Red Pre-Production machine.  The 6 mm threaded holes stripped their threads, the hex head screws having been removed and installed so many times.  Sometime, approximately 1971, the Red Pre-Production machine was dismantled and crushed and the remains sent to scrap.

approximately 1971? If it went on for about 3 years then it couldn't have been crushed until 1973!

You got it. Reminds me of the news tidbit today I heard. A priceless Picasso worth $45K was stolen locally. Well which was it, priceless or worth $45K?

Bob Jameson Hansen died in February, 2013. He was 90 years old when those videos were made in 2009. I am sure he was having an elder moment when he made the "left side down" comment. He also called it a CB450 at one point in the presentation. The factory pictures clearly show the right side down for the frame installation. That was quite possibly a handlebar fairing for a CB450 or such that they were using.

Please accept my apology Mr. Jameson.

Corrected my post. Bob Jameson may still be with us. But he was quite aged at that presentation as well.

Marc, what is the link to this? I searched SOOC Forum but could not find it.

Thank you RR. I was curious who wrote that and it turns out to be Steve Swan. Needs to check his math or dates doesn't he. 

[Don R]

Bad math aside I enjoyed reading this information. I like the sooc site but it's really slow there. I need to check to see if mine is on the list.

I was not slamming Steve. He is one of the Sandcast Gurus.
Yes, I check it daily for the nuggets that pop up however infrequent they may be. It is a truly dedicated site and group of members.

[Powderman]

I can't seem to post anything there as there is no way to register and there's no traffic at all in the classifieds. Makes me wonder if anyone else is able to get in there and do anything but read what's there?

[Don R]

I just posted an update in the owners bikes thread on sooc. It was a lot slower than here but worked. I want to get mine in the timeline, not sure if that part is live, haven't tried it.

Speed seems OK to me. I sign in and check every day. The banner that scrolls along the top says,

Was able to see Don's post just fine. The epoxied hole is normal and was used in manufacturing process to drill an oil galley.

I sent an email, as per instructions, to get registered at SOOC.com. I received a reply from Wayne to give him my user name and he would set me up. I replied and asked if he needed a password also. I have not heard anything back now in almost a week.

enjoyed reading this thread.  Bob Jameson started the first Honda tech school in Racine Wisconsin after he returned from Japan.  it was a real privilege to spend time with him at the 40th anniversary meet hosted by the AMA who gave SOOC a huge tent to share with the CBX fellows.  the red pre-production sandcast was used as the machine that tech students learned on.  Bob said he rode the red pre-prod bike to and from the tech school to home near daily, it was completely dis-assembled in the morning and reassembled so he could ride it home at night.  he said the engine had been taken apart so many times that the 6 mm threaded holes stripped and had to be heli-coiled.  one must remember that back in that era, no one was concerned how many screws held on the clutch cover nor if the cases were rough unlike post-7414 cases.  These men were concerned they would have a product that was reliable and would be a sales success considering that 4 cylinder engined motorcycles historically were not easy to maintain and lacked the reliability of cylinder  engine.  Honda was concerned that their product would be easily maintained by the average owner, and certainly dealers for sure.  the number of screws holding clutch cover and sandcast cases were immaterial to these men.  in fact, Bob expressed surprise at the 40th meet when he learned the clutch cover on sandcast cases are held by 9 screws.  Bob said the first sandcast was built by the engineers who had a part in designing the CB750 beginning in 1967.

 Thanks Steve, I always appreciate hearing a 750 story. An occasional re-read surprises me with my own thoughts at the time.
 I always get a kick out of the guys insisting which bolts had an 8 on the head and which 8 it is, somebody's engine must not be original because it's 400 numbers off and 200 is normal. I've always believed Honda was more concerned with manufacturing good bikes than maintaining continuity of bolt heads and which parts to use during a model change. I also think it sometimes took multiple vendors or locations to get some sub assemblies made.
 Just my thoughts on the subject. I also believe if they weren't cast in sand, the mold was.

Hi, Steve, long time no see!
I think I have as many 750 engines here now as you had when we last met. Did you sic these folks on me? I'm working on a K0 now that has diecast crankcases, but has a head with DRILLED oil jet holes(!). I thought these disappeared with the sandcasts? The head and cylinders look very 'sandy', but the cases are definitely not, and are close to the owner's K0 1969 frame number.
