No August, my good friend, these are well taken points. We're talking about a plywood base here, so the micrometer is featured just to prove I have one I don't tend to take my frogs to the extreme (like Charlie does), so a flash at 220 is probably the best this one will get. From a machinist's point of view, this device is unthinkable. Bow in the base, unequal stones, set on glue, etc. It's horrific.
August, I review your comments with extra care, given my respect for you and your craft. You'll never offend me with a comment or suggestion
Pretty soon everyone will have them thanks to Al. This came out of a conversation around his broken frog.
One thing to consider might be a stopped dado to allow for sanding of the lower part of the frog below the adjuster. The tradeoff is that it would shorten your stroke. Also, if there are concerns about plywood, MDF might be another option.
Thats really cool Al.
I will make me one also I have plenty of frogs that are screaming for some attention.
I also love the little fish detail on the base!
Best thoughts,
Mads
