This Weeks Mystery Tool?

Hi all,

This weeks oddity from a tool lot:

Seem very well made and has been hardened and ground. Perhaps not a tool but a part of something? Any thoughts please?

Cheers, Martin

looks like item off something... ratchet, release mechanism, foot operated lever off a brake press of some type, over speed trip mechanism from a turbine... to guess a few ?

George.

Hammer head for several applications in certain order. Oops

Foot operated process switch of some sort.

Trip lever out of a machine tool or artillery piece.

The long arm is reminiscent of an iron for holding down a (wood) plane blade, possibly pivoted around the hole and tensioned by a jacking screw under the short arm. Nothing like it in Salaman though.

"Ratchet" stop with handle for engaging / disengaging from toothed gear. Very large clock??

(Martin - you will need all your marketing talents to aim this in the right direction - "paperweight" is my best .)

Hi All,

I think I get the general gist here

Clearly I have not found a hitherto unknown masterpiece of English planemaking by NORRIS.

I have to ask as sometimes the unkown to me is blindingly obvious to someone on here and the item now destined for the scrap box may have been of use to someone and thus possibly of some value.

This may be a good time to ask if it really is OK for me to post like this or do people feel that I am wasting time and bandwidth. I fully own up to the fact that I buy and sell items and am therefore guilty using this forums knowledge resource to further my own interests at times.

If it is felt generally that this is not on please let me know.

I do read the build threads on here voraciously and glean all I can to improve my own machining skills which I enjoy immensley.

Cheers all, Martin

I for one think it is quite interesting to see some of your finds. Amazing what people throw out in boxes!

As to the item above I would go for a machine part, some kind of trip mechanism where a cam runs on the end of the longer arm. Almost like a bit of a Corliss engine valve gear.

Keep it up, Martin

You are open about what you're doing, and the puzzles are often interesting.

"If it is felt generally that this is not on please let me know."

Keep going Martin - 'tis nice to hear from darkest Dorset!

Rik

Sure beats the "What lathe / mill/ drill or any other common workshop tool should i buy " threads that pop up on a mothly basis !

Thanks guys, will keep digging around then!

Martin

The item is reminiscent of a sear or part of an interupptor mechanism. most likely from a machine gun?

Clive

Maybe it's a fancy scraper

To me it looks almost like a foot pedal though it's too small the large flat been a stop under floor level. The opposite flat acting the master cylinder. The fancy shaped bit at the top to hold the rubber pedal.

My guess, the ratchet pawl for a shaper auto feed.

I like the brain teasers too. It often comes down to digging deeper and quicker in Google than MichaelG

Might it be part of a 'hit and miss' governor mechanism, as found on stationary engines (etc)?

Cheers, Tim

I it think it some thing part of printing machine norm

That sort of 'back-handed compliment' gets rather tedious, David.

I'll be grateful if you would desist.
