Tools I would like to be able to buy !
(OP)
As an automotive technician, and NOT an engineer, nor someone with even the slightest ability to draw I often have ideas for a tool to make my job easier but no way to create them. Frankly I don't really care much about the process required for patenting etc. anyway so tell you what. Here's what I want, someone make it!
Air Chiesls (hammers) have been around for a while. But there is one specific use that they would be great for, but the repeating nature of the tool defeats any real chance of doing so because you cannot control it once it starts hammering. The use would be to install freeze plugs in the side of the engine block, which often means the tool would have to operate at an angle. It also must be able to hammer in single shots per trigger pull for precise control. One added advantage would be if the hammer strength could be adjusted as well from a slight tap, to the equivelent of a full arm swing with a 20oz hammer. When confined by clearances, many times a technician cannot get any room to swing a hammer, but a properlly built tool would not need the space that a regular hammer would. As far as the "angle" portion of the tool goes, I have some ideas but they would need drawn and tested for practicality as well as durability.
OK There it is, You build it, you can claim it. But someone build it for me!!!!
There are more ideas from where that one comes (VBG)....

As far as I know, there is no tool beiog produced that would act as I have outlined. The single hammer hit is simply not in use at this time, and a low cyclic rate, simply wont work because of the precision that must be used with each strike. The tool must be positioned precisely, then struck, then repositioned, and then struck again until the task is completed. A multiple strike could allow the tool to be misspositioned and then the soft plug or surrounding material damaged when the next cycle automatically occurs.

Folks there know an awful lot about tools.
All I can think of is the nail driver that uses something like a .22 blank.

Be careful when you google this, you'll get a bunch of sites by PETA and the like showing animals mistreated etc. in slaughter houses. Might put you off burgers for a few hours.

I think you're looking for a "single action" or "single blow" air hammer... that terminology may help your search

I think the 'big one' against the side of the car would work but would necessitate a dramatic change in the shop's liability insurance policy!

Anyway, I hope someone can figure out how to make the tool that I would like to have. The current tools designed for this operation are terribly inadequate, and there has never been a real solution except for removing the engine so that there is straight on access to drive in the replacement plugs. (FWIW, bolt in plugs have a high failure rate)

I have never seen one come out of it's own accord. I have only ever replaced them because of corrosion. I only ever use brass replacements. I do play with boats that are cooled with raw water, sometimes salt water.

I have replaced them many time using a socket of the appropiate size, and a heavy short handled square headed hammer, only need an inch of room to swing one enough to fit them.
I have heard of an expansion plug, rubber with a screw that is tightened to expand them. No idea how well they last.

Was told it couldnt be done, so
i went and did it!

My race engine plugs are usually steel, cup or Welch and, "set screwed" or tapped and plugged. The only street failure I have had in recent times was on a '95 Chrysler LHS V-6---all six OEM plugs failed under warranty. No explanation from the dealer.

I have gone away from the gruelling frustration of fitting these bastard things.I now freeze them with liquid nitrogen,carbon dioxide or dry ice.I find it sooooo much easier compared to not doing it this way.
RE: Tools I would like to be able to buy !
Do you mean core plugs in an engine block? (Sometimes misnamed the freeze-out plugs.)
For any oddball automotive tool, try Snap-On.

Use either a proper fitting socket or a seal driver kit. The socket can shrink the plug if not used properly, causing faulty sealing. We use Permatex Aviation Seal on the plugs before installation.
Perry Harrington
Just went through it with a Rover V8 not too long ago. Just clean up the recesses, coat the plug with a good grade of sealer (I used Permatex 2a - non-hardening) and tap it in square using a driver that is a close fit to the inside of the plug (I turned one from scrap).
As said above, don;t hammer the center down or the plug will "shrink" - you want the sides to remain parallel, hence my comment about a close-fitting driver.

If no one is interested in designing and building a tool that can do as I ask then this thread is pretty much done.
RE: Tools I would like to be able to buy !
Pushing a device like this up into a gap where you can't directly support it will most likely limit its effectiveness wont it?
Perhaps you could design it to brace against the body work but you'd need to be careful.

I can envision the fact that the tools needing to change mechanical direction could be used in some fashion to dampen the shock load. Something like the throw on a crankshaft. I can envision the hammer power traveling slightly past the actual impact point and then the motion being levered so that the piston would hit the freeze plug and then timed instantly afterwards, the crank throw would then attempt to move away from the block, which would cause it's own momemtum change and dampen the thrust.
RE: Tools I would like to be able to buy !
Like I said, I've done a few in the last fifty years and, even the 'easy' ones can present problems. I prefer NOT to use a sealer unless there is corrosion present in the hole. Also, there is a world of difference in the installation of a 'cup' plug and a 'Welch" plug.
Finally, I have had two engines freeze and break, a six cylinder 48 Plymouth and a four cylinder English Ford. Neither of these engines pushed out their "freeze plugs"!

Might want the hammer to open a port on the air cylinder so that mostly it's only hammer momentum that gets applied against the plug.
