Combination Hardy stake holder and swage block

Recommended Posts

Hey guys, Not entirely sure where to put this but I had an idea the other day. My rail anvil doesn't have a hardy hole, obviously. Was watching youtube videos of various hardy tools in use so I thought to myself that would be handy to have. Rather than have a single use tool...Why not get a half egg milled out of one side, a half sphere out the other. Maybe even some various sized rounded and v notches in the edge. Then you take it out of the vice turn it and use like a limited swage block?

How much 'volume' would you need around the hardy hole to avoid breakouts? Basically my local engineering shop is looking for dimensions before they give me a price.

Depends on the material you're using. Cast iron is going to need some hefty mass; mild steel, somewhat less; high-carbon, less still (depending on what heat treatment you give it). 

If you already have a post vise (I'm assuming you're not planning on doing any heavy pounding on a machinist's vise), why not just hold the hardy tool in its jaws?

I don't have a post vice, yet..:) I have a Record No 3. Engineers vice I obtained for free. Which was nice..:)

The thought being i'll only be using the hardy tools for specific hot shaping tasks so I won't be bashing on it full force. But that's my thoughts, I'm more than willing to listen to others...:)

I was planning on letting the machine shop deal with all the machining and hardening, mainly because i'm not fully competent yet..:)

You definitely want to minimize pounding on that vise. Consider a portable hole or a striking anvil with an integral hardy hole. Less expensive, and more appropriate to the task.

The mini-swage idea is interesting, but probably more trouble than it's worth, especially when you're just starting out.

What's a portable hole? Does it come with a lid? :) 

Honestly, If I could find an decent affordable anvil with a hardy I'd go for it.

Wasted too much time waiting, trying and failing to find one. The prices are so high here it's almost worthwhile getting a new Kanca or NCTools one.

The rail anvil is enough to have gotten me started..:)

There are a couple of articles on the forum about portable holes. Pro tip: ignore the forum's search feature (which is ... quirky) and use the search engine of your choice with "iforgeiron.com" as one of your search terms.

It's basically a hardy hole not attached to an anvil. Usually mounted on a stump or heavy stand, sometimes with a striking anvil.

Various ways to make them.  I was recently given a piece of bulldozer wear plate that had 6 1" square holes in it and was thick and heavy itself. I passed it on to a new fellow when he bought a 4"x8"x8" piece of steel to use as an anvil (72.5 pounds) US$20 for all.

Don't know where Rosyth is; but is their any ship building/repair or oilfield (I guess gasfield) work that generates heavy scrap or drops?

This is my improvised swage block. Got some radiused ground in it and it has a non traditional hardy of sorts

Cast steel tractor weight

i just use it on a stump with lag bolts fencing it in. I often flip it over or stand it on edge so I don't fasten it down.  Weighs about 110 lbs

Guess I should think harder. I suppose most of the innovations have been worked out in the last couple hundred years..:)

Rosyth is on the east coast of Scotland. There is a dockyard but it's a MoD (Ministry Of Defence) property so all the work goes on behind the security fence. No civilian access without a pass..:(

Got any friends who work there? Or at the dockyards over in Leith?

Are you of an age that you could stand a worker there to a pint at a local pub?  Do take care though; it's such a pain trying to explain to the Rozzers  why you have a section of ex-warship in your boot...marked with a High Explosive stencil or worse a radiation trefoil...

Now if you really want to depress yourself: go down to the Science Museum in London that has James Watt's workshop in it; yes the entire thing in the exhibit hall---including a large number of items they still don't know what they are...Watt managed to change the world in a workshop that most of us have ones that outclass it by orders of magnitude! (I must have 4 postvises larger than the one he had!)
