Farrier's pliers for working with horseshoe nails and cooper's iron for tightening barrel hoops.

These are not usual but not so strange. All three of these are home-made, my design, for a particular use for a project. The two shaves have blades scavanged from a set of jointer blades for a yuuge jointer I never owned. I really can't remember where these came from. The three high-speed steel (I think) blades are just like the ones in the six inch jointer I inherited, but like ten inches long.



It turns out I won't need a jointer for the front porch project after all, but at the very least, I want to spin it up and joint a piece of something to demo it for a buyer.

The weird looking thing is a jig to hold the six-inch jointer blades to sharpen them by hand on the bench grinder. I made it from stuff on the bench, eighth by half inch steel bar and half inch copper tube for the keepers. The blade fits in the notch at either end, and the copper keepers keep it from escaping and making arterial bleeding. The straight bar rests on the grinder's tool rest, and serves as a guide to keep the bevel even and straight. It's crude but it did work well enough to get a smooth clean face on a trial run, with a nice fluffy ball of shavings you could read newsprint through.



The two shaves are my design, for working on the stupid black walnut chair I've been trying to build since forever, it seems like.

The pipe and blade shave is for planing a tight inside corner of a smooth bend with a flat face. The challenge is the fact that the continous curve of the design changes the angle of the woodgrain, so it has to work smoothly through end grain and flat grain, back and forth, without tearing out. The walnut is hard and dense but can be brittle across the grain.

It's a little difficult to see. There is one pipe of smaller diameter inside the outer pipe, both have slotted through holes such that the blade fits through and allows shavings to exit. It's a drive fit for the two pipe sections, and that provides the friction to hold the blade in position as it pushes through the wood, and to be adjustable for depth.



The other is a shave for a space that is fully enclosed, too small for a standard tool, and needs to make the same kind of cut for a flat faced curve. A handle can be removed from either end to insert the blade into the tight space, and then re-attached to use both hands on it while making the cut.

I'm working on a similar, one-handed shave with an adjustable depth flush cutter like a shoulder plane, in order to cut a long continuous dado in the same long curve with both convex and concave bends. I'm probably reinventing something real woodworkers use for some specialty like luthier-ing. Or pig farming.

I grabbed the image off the web. Deep in storage I have something similar, it will draw half of an ellipse, just turn it around to draw a full one. Adjustable major and minor axis.

Not mine, but I own one.

Nice sets of gronicle adjusters, pullers, tighteners, and shavers.

[Peerie Maa]

Yes it's a plane, but what for?

A trifecta of tools, two are related, one is ... just weird:

I've got one of these tucked away somewhere that I built 20+ years ago - from when I had a client who sold nifty woodworking items. I supplied her Shaker Boxes, and she liked that I would happily - in addition to the 3 stock sizes - do a custom size.

a shaker oval box for a ellipse drawing device?

oooo, that looks promising

Ayup. All ellipses are ovals.

[Garret]

A different "ratchet". No actual ratchet at all. The separate part on the end away from the head turns either way & turns the socket. Not sure when I'd use it - it came in a lot from an auction (didn't even know it was in there when I bid):

i was thinking it was pretty cool

It was. That jig was a revelation when I found instructions... way back when. One can even adjust the shape of the oval. Short and fat to long and skinny... simply by changing the attachment points on the winding arm.

10 point dividers, we used to use them for interpreting old wet side scan sonar records. before digital side scan. Also, analog seismic records because all depths are measured in time, vs rock type.

Computers are tools. I've got an assortment of these


and these


and boxes of assorted bits and pieces to control them and be controlled by them.

Rev counter?
My Uncle won the Morgan Engineering Prize at Malvern College pre-war. He was given a Micrometer and one of those in the pic. Both in nice presentation cases, embossed. He gifted them to me when I went into engineering. Still on the shelf in the w/shop, but little used.
As for the name of the prize, think Morgan Cars.

Nice, and I would like one. But, one can do half decent ones with two nails and a bit of string. The fun is spacing the nails.

Nicely done
I operated the central tool room and machine shop tool crib for 1200 tradespeople at FMF Cape Scott for 26 years. These were issued in control systems and sonar shop tool boxes.

Tachometer

Ding ding ding!
Used back in the day for feed/speed calculations in the machining process. I had several of these in my tool crib and never issued one in my life, although journeymen often asked to see one at the counter to show new crops of apprentices.
