Jlblohm, i like how you roll.. Anvils at the ready.

I am pretty much the same way.. I'll be keeping an eye out for one or 2 of these now.. I may even make something close as they look pretty simple in an elegant way..

How many pairs?

That is a beauty you made there and it is a sweet wrench.. What a great wrench for a fast design.. No messing with the little knob.. Just turn the handle..

Yes he did.. LOL.. What are you making?

You'd have to go elsewhere.. Ninjutsu isn't a flashy marital art.. Some would argue it's quite crude.. Not only that "He's a new student".. In order to really show it, you need a skilled Uke (training partner) or else they just get hurt.. It will be mainly climbing skills related..

Wow, great work.. Your works shows you have an eye for good hammer control and a good "As forged eye" ( it looks finished as forged)... For most it's an acquired skill and you seem to be a natural.. Looking forwards to to more shots and work..

Never heard of it.. Good to know in the future.. I've never been to a hammer-in.. What went on or what happens there? You going to the meet in NH.. I'm looking to recruit.. I"ve been tasked with making 20 sets each of fire rakes and shovels.. As the Military signs read "Looking for a few good men smiths.. "

My first real hook at age 8 was big bertha.. 1/2" round triple hook... I could barely lift her. she was bent in the middle to form the eye and my Dad welded in the 3rd hook after I bent it up.. Just some scrap 1/2" threaded end rod we had.. Everyday when I got home from school we'd be out just me and her trying to get her to work.. LOL.. She has probably 10,000hrs on her if not more.. I give her to all the new students to work with as she is a beast.. A proper/mastered throw is needed or she just laughs at you in disgust.. She taught me to throw with my whole body and to be accurate.. Her getting caught in the V of a tree was a climbing situation no matter how tired or fresh I was.. It made me a much better climber.. I filmed todays training session and will post it to my personal page YT page.. Nothing exciting, Jumping, little hand to hand (with a newish student), some tree climbing, some slack rope work.. I'll see if it's worth even watching once its processed.. It takes a full day to convert the footage as it's a 360 video.. Here is a picture of a few hooks.. the large one is for students.. My personal ones are the smaller. As a side note the rope dictates hook size..

Thomas, I always thought they were about the same (control current amps or volts?) What is the difference?

JHCC, while i like the design overall, I'm a little baffled as to why you went up with the bosh instead of a more conventional sideways lay out? With having it that high it will mess with a hooded or down draft affair vs a low mounted bosh.. Looks really nice.. When is the first firing? Also love the rheostat.. On/off function is superb.. Set it and forget it.. Just a flick on, flick off.. Excellent. I dislike slider gates to control airflow..

Frosty, yes having at least some background knowledge as to the age can say a lot to what information is shared.. if someone pulls something off the net and uses it, so much to them.. I personally would never just share the information out of knowing the full potential for what can happen with miss use. Been there, done that, got the ribbon and still walked up to get it.. Thomas, I breath hold dive, Free climb, have done deep water deco dives, cave diving, etc, etc... I have never been injured with what I consider to be life threatening. (both elbows are just bigger now and it was only the tip that got broken). I have sustained some really bad injuries (99% work related) but not usually involved with any of the things mentioned other than Deep deco diving.. (type 2 hit) still have some paralysis on my left side.. Most can't see it as I have trained really hard to even things out and to help with regen of new nerve path ways. (same with back surgery, L4, L5 colapsed left side, diving related whos to say). but it can be noticed when I smile or in bright sun light as one pupil will dilate more then the other and my face will only squint on the right vs left.. Irondragon forge and clay,, I never had freinds like that with beer.. Everybody was sober.. 99% of my students went into the military and most tried out for SF, few made it and offered up the comment of " With the training they received there was nothing that SF threw at them that was new".. And the ones that didn't finish said" While in training i asked myself if this is something I really have a desire to do".. Both of the answers or comments is what it's all about.. Enough of the thread hijack.. What ever happened to the guy who asked the question? LOL..

Ninjutsu.. there is a ton of information on the web.. Some true, some not so true.. History being written by the victors has a lot to do with how things are looked upon,. With that in mind, A Ninjustu person was eventually made Head of homeland security for the Emperor or Japan..

I like your sense of humor.. Yes, it is true, to young or to old.. How many pull ups can you do? When was the last time you climbed a 3/8 or 1/2" rope? LOL.. Not to get it, but to understand the dangers involved.. Last think I want to do is give information.. Unsupervised information to a younster and set them out without training.. This is pretty serious stuff.. It might seem like a joke kind of thing, but the potential for death is very high.. problem is i know first hand the dangers involved with use of such a tool.. Luckily my training and perseverance has kept me from sustaining injury or death when such things fail.. which they do.. ive done a few 30' falls and a 50' fall once with nothing but some bruises and a few cuts. I did bust an elbow 2 times on the same spot 2 years apart.. it propmted me to design a different kind of hook.. There is no guarantee of a hook being fully hooked as there is no way to see what it is hooked on.. The ability to climb rope smoothly is a best application of skill with a hook as any jerky movement can be disastrous. Again, I've been there. As an example, one of my students as a test to see him fully understanding what has been taught (he was being a little cocky as young men can be) Was given the task of climbing up a shack using my rope which is 1/8" static line. There were 2 spotters.. any how he threw the hook and set it all properly done.. he climbed up the first 7' very smoothly, (i could see him fatiguing). Then it happened he lunged for the next hand hold. Next thing he knew he was on the ground flat on his back.. The students at this point have extensive trainung and experience with short falls like this and are taught how to land.. the spotters job is to correct only if there will be head or neck contact with the ground.. This was his first "live" fire test.. After he gained his senses back from the shock of the fall i asked him what happened.. " With a humble look, he said " i was getting tired and forced the climb. He then said, i was no where as in good of shape as i thought and can see now why you tell us to be smooth and fluid and to be good at something one must practice.. The training can be pretty intense and its a no "shame" zone.. if at anytime a person feels they arent up for something, all they have to do is say so.. i encourage this and opting out perfectly fine..

YUP, that be it..

I will be curious if it works. the Venturi effect can be a tough one to work out as there is a velocity factor.. You guys really make my brain smoke as I end up thinking about stuff from over 30 years ago. I looked into it years ago and a belt driven squirrel cage blower is what I was steered to as a cost efficient way to go.. there were direct drive squirrel but they were much more expensive and was told with the motor so close that the heat transfer might become a problem.. No problem with a Belt drive.. I might look into it again once I get the shop up to vent the smoke up a flue to shoot it higher into the air..

If you run with a down draft hood what would you use for a sucker? While I am a fan of using anthracite I also dislike the smell of it far more than soft coal.. With that said the smoke isn't the problem for me as much as the smell.. Despite what everybody say's in regards to soft vs hard coal, The fumes from hard coal with the sulfur gets me just with the little smoke produced.. The only time I have a problem with the soft coal is when I clean out the firepot and throw the clinker into the pail.. Mind you I use a chimney and would certianly use a stack with both... My forging career started out with wood fired boiler which then was converted to hard coal so worked with this also.. I used hard coal in my early forges but switched over to soft once I found a place to buy it.. Once the shop is up, I'll offer different forge types for people to try..

I can't offer any suggestions other than to keep the hammer separate.. This of course depends on what kind or type of hammer.. My new shop will be going up in the next few months and won't be putting a floor into the shop for at least a year or even 2.. It will have a full footing and frost wall and once I get everything arranged the power hammer (200lbs Fairbanks) will be moved into position and a proper footing will be installed... I'll run it that way for awhile then pour the floor.. 40X60 is the shop size steel building..

when do we get a full frontal on this setup? What did you come up with for a hood setup?

I use one all the time and teach it's use in Ninjutsu class.. A grappling hook used improperly will get you hurt or killed.. There is a skill set that goes along with it's use for both hooking it and then retreivel.. A single pointed hook is the most useful with designs based on type of work used for it.. They actually come in many designs but the single hook style works the best.. Quesiton becomes how far you can throw a rope and again it becomes what kind of skill set you have.. There is no reason to forge weld a hooks eye as they can be upset and then slit and drifted.. What size rope did you have in mind? Also stay away from Sisal or hemp as these degrade quickly and don't handle abrasion or grit stuck in the fiber well.. They have a tendency to break, yes you read it "Break" when it's the least opportune time.. As with all the stuff I write or post about I have extensive back ground in the use, construction of such devices.. 45 years to be exact and have built 50 climbing hooks from 2" up to 8".. I use one regularly 4 or 5 times a week teaching.. Last week alone we climbed, tarzan swung, repelled and slack rope walked all using the hook and rope. The hook design is based on what or where you will be using it but again, a person can get hurt or killed without proper training as there is no safety line or safety back up.. No belay device or the like.. Before I will offer more info I need your age... By the way, the rope will do more damage than a properly designed hook.. Also it depends on the type of tree.. An ash, oak, elm, walnut will do ok.. A birch, or maple will not fair as well with the rope dragging across the bark and will rope burn the tree.. The thicker skinned trees do very well..

For what?

Nice.. Keep at it and enjoy..

As a clarification to TP's post. or to add more info.. TP if this isn't what you meant correct me.. But the information I wrote still plays true in use.. He means fill the whole thing green soft coal, Ideally soaked in water, which basically acts as the firepot.. The Coal will coke around the air entering it, Thus creating a firepot of sorts.. To add new coal to the all ready burning center, you add new green coal to the top edges of the fire which will then coke.. This is then added to the burning part of the fire.. You can use water to control the area burning if you use to much blast or just use the right about of blast and the fire will maintain the size vs burning into the green coal in the hearth bed.. On a steel bed hearth/forge the grate is still cast iron... The bed being steel will be prone to rusting if heated or left to being heated un protected by a heat resistant coating or source.. I've had firepots glow a nice red color when doing heavy work.. Without a good way to isolate the heat it will shorten the life span on the hearth bed.. But hey, different strokes for different folks and the nice thing about steel hearth beds is they are easy to fix.. Fire management, or using a fire in an appropriate way is rarely discussed.. Coal or any fuel not exposed to O2 will not burn or it will burn slowly as in the edge of the tuyere or grate, the fires size can be controlled more or less with the air being fed into it and to augment this water in a sprinkling can is to be used.. . ..

If it were mine i would line it, and create the shaped fire pot i want.. What most fail to recognize is without the clay you have to leave excess coal fines and crushed clinker to get any kind of height to the fire proper. This crushed stuff is wetted and packed in just like clay.. Without proper fire depth one will have a hard time creating a neutral or carbonizing zone in the fire as there is no depth so will end up wasting a lot of fuel to build the fire up to the correct height..

Sorry that is a great question but goes above my pay grade.. Back when I used my hammer it was only for a brief time and used no foundation at all.. with getting the new shop up I'll be putting in a foundation but it will be based on what is recommended by the MFG's.. I would imagine they came up with a design that they liked best or shown the best results.. Sometimes with items like this the rebar is a given as it was common practice or a known entity.. I've used a lot of Factory repair manuals for Auto repair and they will leave out information which they consider to be common sense or a known factor and is the reason they are factory manuals vs " How to fix your VW" .. A lot of the newer hammers don't even have foundations and just get mounted to the slab of concrete... What or which hammer do you have I'm guessing a Beaudry? They make/made excellent hammers.. I'd be a hammer collector if they weren't so big and hard to move...
