A Walden Valve Grinder is a necessity...

[woody 73]

A tool that is listed in the AA Web-site but not shown in pictures so sit back and enjoy the show.

From the AA web-site:

"The Company became the Walden-Worcester, Inc in 1914, before that Date it was called the Walden manufacturing Company". Dating this tool from 1914 and beyond.

The Ad is marked Aug. 1915 and the tool is a Walden VG3 hand tool marked at 30 cents. The other link on the AA Web-site is a picture of its bigger brother the VG2 both used on Early Ford Cars.

Even after a Google search I still can't get my head around how this works. It seems to be what would be currently referred to as a valve lapping tool (ground glass and oil for media). These were for inline side valve engines evidently but I don't understand how the tabbed end would grasp a valve. Surely the valves wouldn't be notched.

Some were notched.

Oh really! I wouldn't have guessed that possible. Thanks Zeke, it makes more sense now.

For a little more perspective........that tool is from a time in which many 'not-wealthy' Ford model T owners had recently replaced a horse with the T, and had to learn to do the necessary maintenence.....and there was quite a bit to do.... by themselves.....some pretty serious learning-curve', that.

Remember, in the 1910-20-ish era, when the T became popular, there were also pretty minimal grades of gasoline available, which choked the engines with carbon build-up, requiring a 'carbon and valve job' all too often.

The valves were soft steel, compared to modern valves, and seated on the cast iron of the block. What they then called 'grinding', we'd now call 'lapping', rotating the valve in half-turns back and forth, with an abrasive, until the surfaces were smoothly fitted together to 'hold compression'.

The engine makers, and replacement valve makers usually used either two shallow drilled holes, or a milled slot, in the head of the valve, for a tool which would rotate the valve. Some replacement valve makers 'cheaped-out' on this detail, so rubber suction-cup valve lapper tips became popular.

Even today, a century later, when I'll do a set of 'three-angle' valve seats with modern hard seat grinding equipment, I'll 'lap-in each valve to its seat, with ultra-fine compound, and a 'suction-cup' valve lapping tool.

I just picked this up this week and thought it was for lapping valves. Thanks for verifying that. Mine has a disc on the end with two pins. On the handle it is stamped "No3 Walden-Worcester, Pat Pdg." It is kind of hard to read in the photo because F.L. had to go and stamp his initials on it.
