HK1 Expedition tools

Here's yet another "revolutionary wrench" concept. Slide the appropriately sized wrench end around the nut you wish to remove, open the central valve (pointing down in the image), slide the piston in the direction of the nut which allows a third jaw to securely hold onto the nut when the valve is closed. There is a non compressible fluid inside which moves the jaw. Needlessly complicated? You be the judge.

 As with so many of these things, it will work for some nuts and bolt heads in some locations, don't throw away your sockets, box ends, etc...   More here.

 As any 17 year old knows, "A good flame job will add 20mph to your top end..."

Merlin engine cutaway

I don't see an artist's name... the actual cuts in red are a nice touch. 

The 27 litre (1648 cu. in.) Merlin V12 produced 950 hp as a prototype in 1935, by 1940 it was up to 1350 on leaded gasoline and by 1945 it was producing over 2000 hp.

We used to make things in this country, #362 Ker & Goodwin Machine Co.

   The company was founded in 1897 in Brantford Ontario, by John Ker and Abraham Goodwin to manufacture lathe chucks, face plate jaws, and all-steel chucks. 
 After WW1 the company re-organized as Ker & Goodwin Machinery Co., Ltd. and along with the lathe accessories, began making oil engines under the "Hvid" Patent. The Hvid engine is a compression-ignition engine which used a low pressure injecting system, likely to separate itself from Rudolf Diesel's engines and patents,
 Abraham Goodwin’s son took over after he died in 1946 and reorganized as the Goodwin Chuck Company Ltd. in 1951. It was last listed in a Brantford directory in 1973.

Honda Gold Wing cutaway engine

Timing belt, HyVo chain and lots of gears... Was the Gold Wing the first motorcycle to use a timing belt?

Finnish GP 1975 push start

 The great equalizer. I think they should bring back the push start for MotoGP ( Maybe F1 too!)

Monday Mystery; Nu'twist magazine wrench

 Here's a tool I didn't understand, the box contained no instructions, the picture on the box isn't helpful, the socket part offers no clues.. Garage Journal mentions it was patent 2220354 issued to Robert LeRoy Sheetz on Nov 5 1940, but those do not check out. Anyone?


Yikes, the idea for that poster must have come from a nightmare someone had...

WW2 propaganda

 Brutal illustration, but the goal is to dehumanize 'em...

Crestogrip waterpump pliers

 According to the always useful Alloy Artifacts site (scroll down) These box joint (or slip joint) pliers were trademarked in 1957. The detents for adjustment don't look like they would be strong enough and also that they would wear quickly. The groove joint type of pliers below are a much stronger design.

Up on blocks.

Looking for all the world like a model railway scene, this Wiscasset, Waterville and Farmington Railway narrow gauge General Electric switcher seems to be having some heavy maintenance done.


Westinghouse Mazda automotive bulb kit

Nice little tin box automotive bulb kit, unfortunately it was empty so we'll have to guess what was in it. Looks like it might date to the 6 volt era so; a couple of  #1154 dual filament bulbs, a couple of  #1129 single filaments... some small 3 watt #55 instrument panel bulbs... what else?

More Unadilla


All makes, all models... all being used. Great event.

One of my vices is vises; Yankee #1993 Machinist Vise


An unusual vise patented in 1915, and built by North Brothers of Philadelphia who appear to have been in business from at least 1875 till the mid 1950s, though they were bought by Stanley in 1946.

 They manufactured hand tools and small appliances and are best known for their line of Yankee ratcheting screwdrivers. Previous post here.
