Here's a simple tool I made up for clearancing blocks, or
checking to see what fits when useing different rod or stroke
combinations or different blocks. I just made arms with hole
centers for 1/2 stroke foe example a 6" stroke is a 3" offset, or
3" center to center on the holes. I made different slugs to fit
different main bearing bores and rod end bores of different
rods.
I don't know if it's NATPA legal to use when building a motor or
not, but it sure is handy. Maybe a few of you will make
something similar or have made something to make the job
easier. I just hate mock up, grinding, clean up, over and over. And I get way to many questions of what stroke fits with what rod in this block or that block. I can check things out ahead of time and I like to keep a greater cap angle on the rods when possiable, it makes for a bit stronger rod.
I made this tool up and send it out to people I'm working with so they can check and do a little planning for those who are building their own engines or I'm helping them with the planning, selling them parts, rotating assemblies etc.
