I tend to have multiple projects in the works at any given time. Over the last 2 weeks I have been working with my friend Scott to build a "clean room" in my shop. This is a sealed off area to assemble engines in, allowing me to use my saws, grinders, sanders, etc outside and not contaminate engines that are in various states of completion. Over the years almost all the failures I have seen in engines have either been from simple negligence in assembly or foreign materials getting inside the motor. (I know another local shop where you can get both!). Anyway, I am still trying to perfect my engine assembly skills, but at least I will have the clean part taken care of. The room is air tight, literally. I have a filtered air line coming into the room from my outside compressor, keeping a steady 1 PSI air pressure inside the room, keeping me from passing out and making it impossible for dust to enter when I open the door to the rest of the shop.
In the bottom pic you can see a knucklehead I have bagged and tagged for re-assembly. This one is getting dual carb heads and a fresh rebuild. Every single part has been cleaned, inspected, bagged and labelled before it enters the room. Remember, when you go looking for a shop to rebuild you engine, look at the work area. Does it look dirty? Are their random people walking around unfinished engines? Is the shop open to the outside? Engine building is like open heart surgery -any foreign material gets in there and its all over. Believe me, I know from experience "cleanliness is next to godliness".
