This thread may no longer be active but I have a question regarding JorgensenSteam's Edit 04 on page 2. Is the 55 degrees eccentric advance mentioned for a full sized steam engine what is required to clear the slide valve outside lap (to start admitting steam to the top of the cylinder)?

Thanks to everyone for the assistance on drilling the 4" brass flywheel. I used step-drilling (9 steps) as recommended after SECURELY mounting the wheel to the X-Y-rotary table and used two hands on the spindle handles to limit bit grabbing. It worked fine, thanks.
