Wrench question

I lucked up and found these in my odds-n-ends box.
What do the hex and all the side cuts fit???

There are others who will know better than me, but I'll give it a go.
The lower wrench is standard issue .049. The RH end is for the glow head & includes a screwdriver at the end. The opposite end fits across the exhaust ports for loosening & tightening a cylinder which does not have flats on the top fin. (Earlier cylinders). The large cut-out on the top edge is for loosening & tightening a cylinder via the aforementioned flats. The small cut-out is for tightening a Tee Dee .049/.051 venturi lock nut. The cut-out on the lower edge is for tightening the collet in front of the Tee Dee carb body.

As for the hex cut-outs in the upper wrench, one may have been used to tighten a standard glow plug on a Queen Bee??? Not sure about the larger one. It may have been issed with a car & used to tighten axle nuts or something.

Rod.

I don't exactly remember, but one of the hex openings on your upper wrench might be for the hex prop spinner/nut seen on the earlier Cox engines.

I didn't think of the early engines with a spinner nut. (Space Bug?) I bet that's what it is. Then again, why would it have the Tee Dee collet wrench included if it was made for a pre-Tee Dee/Medalion engine?

Hope Cox International don't mind me using the picture. Thanks Bernie.

That wrench was Cox's attempt to have you purchase more parts and engines. That particular wrench especially. It was too thin and all of it's components do nothing more than destroy an engine. The glow plug portion rips the glow plug, the TD collet spanner digs into the threads of the case and tears the aluminum out, the exhaust portion ruins your cylinder when it pushes a burr into it . The screwdriver, well that's good for going through your hand when it tears the flats out of the head of the screw. The upper cylinder removal portion pretty much rounds over the cylinder flats ruining the bluing at the same time. For a more positive glow plug wrench, the wrench that entirely surrounds the plug is the best option.

Ken, very good description , the wrench he is talking about as a go to would bee the first one here https://www.google.com/search?q=cox+engine+wrenchs&espv=2&biw=1600&bih=770&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjt4vS4pN_PAhXH2SYKHTRnDC4Q_AUIBygC#imgrc=Q2EbovuVcinQfM%3A Thats the wrench i use most the time the others are give away or when the engine is loose enough to use with out damage Pumpkin

Thanks for the responses, guys.
I currently have only 1 .049, a GB, and I picked up a BW cyl/piston I may put on it, but neither cyl has flats, neither wrench fits exhaust cuts (wrench openings too narrow).
Guess I'll need to use my teeth to swap the cylinders. Very Happy

NONONO What i use is a piece of 1" ID. heater hose over the cly with a little heat (from hair drier) and a rag doubled on the crank case and two pairs of channel locks ,, Be easy if one is locked up not to twist the rod ! Thick hose works best , Eric PS> the hose does wear out inside after a while and will cause scratches if too thin .

Well, Darn! I wanted to try out my new dentures! Very Happy

Actually, I use a piece of leather and pliers for delicate ops like this - and very carefully then.

Can't see why they won't fit. So long as you don't have the duel-slit cylinder. In that case you will have the flats on the top fin. Not sure what's going on, unles it's a Pee Wee wrench, but I don't think so.
Oh, make sure you don't insert the wrench into the exhaust port. It just slips across the face of the port so as not to burr the inside edge of the port & damage the bore.

Oh, and make sure the piston is fully lowered. This might be an obvious point, but we can sometimes overlook the obvious.

OK, you were right about the obvious, OER - I was trying with the prop on and had not quite enough piston clearance in the slots.
I gave myself a slap on the back of the head. Embarassed

Thanks!!
