Excellent Dan. The sycamore and walnut make a fine combination. You did well making the wheels and the finishing is beautiful. Your grandson is going to jump for joy.
Praying hands pattern for those who wish a copy. The size I've done is 7 ½" x 6" and ¾" thick. Size of base 8 ½" x 4" and ¾" high (or size to liking). Attaching top to base you can use screws, dowels, or just wood glue. Choose a clock or photo insert. I always have a few on hand as a gift. I have sold many of these. With clock for $85.00 and photo insert $75.00. Many have purchased or ordered two and three at one time in memory of a loved one who has passed on. In memory of one person's passion I had added a scroll sawn fishing rod and box along with a guitar attached to base (guitar sample attached).
Best to use a forstner bit according to size of clock insert Sam. Use a drill press and drill to depth of clock insert (not complete through). Clock should lock into opening. To remove the clock place fingernail below front rim of clock. The clock will snap out.
You deserve a lot of credit helping someone in need. The world needs more people like you. And second, congrats on your new saw. You collect saws like I collect cameras, and I have approximately 125. So be careful, saws need more space ... Lol
