mystery tool time

[Big Pete]

ok folks, my old man found this set somewhere, made by Sykes - Pickavant, the part number is gone, but the hopefully you can see from the pics whats in the kit.

the reamers are straight flute and are marked with appropriate drill sizes, the thing that looks like a socket has spanner flats, and a stepped bore, again marked up with drill sizes.

I can't find anything even similar from SP at the minute. The only thing I could think of was that maybe its for reaming valve guides after insertion, but I really have no idea. I throw it open to the wisdom of the GJ masses, anybody got any ideas?

D'oh, should have put this in the general tool forum, any chance a mod could shift it for me?

Probably not for reaming guides. Valve guide reamers are piloted reamers. They locate on the ID of the undersized bore.

A better photo of one of the "reamers" would be helpful. It may be a screw extractor set, similar to the Ridgid screw extractors. Here is an image of the Snap-on (rebranded Ridgid) E1020 screw extractor set.

It appears to me that the cylinders are drill bushings, although I don't know why they would have stepped bores. The "reamers" appear to be the actual extractor. If it is anything like the Ridgid set, the extractor is driven into a hole drilled into the screw, with the flutes locking against the bore of the screw. The extractor is then turned, and in theory, turns the screw.

Keep in mind that this is a guess. Again it would be helpful to see a better photo of a "reamer". From what I can see, these do not appear to be reamers.

Looks almost like a kingpin bushing kit, at first but to small.

It looks like a stud extractor kit. If you go to the Sykes-Pickavant site and download their Bodywork catalog you can see it http://www.sptools.co.uk/Catalogue/tabid/140/language/en-US/Default.aspx It's called their Straight fluted extractor set. Looks like you is a bushing to drill the center of a stud, drive the remover into it, then turn it out. Not sure though. Here is the pic

I reckon the stud extractor is what it is, I can see how it works now. I think the idea behind the stepped bore on the drill guide is that the larger bore goes over the remains of the stud, and the smaller bore is the the drill guide. Thanks all.

Has anybody used these? Are they are better than the usual type of extractor, or is it just a more convoluted way of leaving a hardened steel core in your broken bolt?

i had a set that i used while i was working on airplanes. i used them when i had to remove fateners that were tourqed to ungodly amounts. never once did they fail me on the flight line.
