Manually operated shaper

[threesixesinarow]

Nice, neat job.

It looks like yours is based on S. S. Miner’s, first published in Popular Mechanics. https://books.google.com/books?id=Zd...20shop&f=false

Miner’s instructions are pretty loose, plus the way the drawings are presented is confusing and I’m not sure all of them are included in many of the pdfs you can download different places.

It’s supposed to have a kind of clapper to allow the tool bit to lift clear of the work on the return stroke, but in the demonstration at the end of the third video yours didn’t seem to include it.

In case it doesn’t, even if the shaper’s mostly going to be for internal stuff I think you’ll get a lot more use from it if you can fit a clapper, especially a more conventional design that allows both the clapper and tool to be positioned at different angles independent of each other and of the the tool slide.

Here is one home made example: Kay Fisher's Metal Shaper Column 58 Those can be locked, and fitted with different toolposts, or can be removed and replaced with solid blocks, like the one shown toward the bottom on this page: https://gtwr.de/stoss-hobelmeissel/ - he also had pictures of a home made backwards-acting clapper for cutting in reverse, but I can’t find it now.
