    Excellent work. What did you use to polish the rods?

    Those rods look a bit suspect to me. Did they check out ok when they were tested? Not that costly to get engine parts properly checked, and its surprising that people spend so much time on preparing parts, which in some cases are certain to be scrap.

    The man has a scale to balance the rods to fractions of a gram. I would have faith the big ends are round and the rods are straight.

    Instead of getting in a term pissing contest like Benesesso seems to enjoy I'm just going to pop in and say great work and meticulous build! Thanks for taking the time to post. You clearly know what you are doing so why would someone try to come in and start a trivial argument? Potato potato go polish your own darn rod! :deal

    I just looked at this on my IPad, the pics look even better on a big screen. I absolutely love the attention to detail. I would love even more detail in your documentation. Specific processes for each step.

    I crave knowledge like this.

    Shot peening is a good idea since failures will generally be from fatigue stress cracks which grow: http://en.wikipedia.org/wiki/Shot_peening

    Finding these small stress cracks is the purpose for many NDE techniques including dye penetrant and magnetic particle inspection, ultrasound and x-rays. I would have to shot peen the parts after going through all the work done so far. I really like the burette measurement setup to match volumes.

    Thanks for documenting all your work.. Looks great and I enjoy seeing it.


    In aircraft maintenance we've also called them stress risers ! Not to prolong a stupid pissing contest.

    Please don't let the arm-chair quarterbacks get to you. I've heard of blueprinting an engine and had a general idea what it was all about, but this is fascinating! I'm looking forward to seeing the rest of the process.

    Seems strange you feel that no proper checking needs doing on 40 year old engine parts, and without that not sure how you are doing a blueprint type job of building your motor?

    For a top level job, I would have had the head crack tested, and checked for flat on top and bottom deck faces, if all ok have hardened seats fitted, and a proper 3 angle valve seat job done by someone with a Serdi.

    Rods checked for straightness, and bearing bores for round, then NDT for any non visible defects. The rest of whats required depends on whether the bike is being used for race or road, but its always worth taking care over parts like rod bolts, as there are a lot of very poor pattern ones on the market.

    Saying that though your build looks a lot better than most, and discounting the fact you have not bothered to get anything properly checked, should make the motor run a lot sweeter.
