Three Jaw….. LOL, I would get fired in my last profession (Babbitt bearings) if I ever set up a Three jaw.

I had to pick just one... Thank you for your Service. How interesting.  Nice to make your acquaintance. 

Hey y'all.

Robert Taylor

Edit:  Yes, now I remember.  Worked in a gas turbogenset component shop, we made "lead" faced bearing pads and retainer assemblies. The mainshaft would ride on five of these pads on a pressurized oil film.  My little Southbend glides on Babbitts...

Hahahohohehe.

I thought I knew everything in the first half of your post, but when you ckucked it in your lathe, my theory went out the window. 

I will lay odds that there are numerous steels that forge picky but machine well - but a form stake? :-/

The only hatchet I've ever thrown is my all steel Estwing when I was on a Boyscout camp out

Have not checked out Fazer's thread in quite some days and weeks! All of the usual suspects, I see... I am mad about throwing all manner of objects.

Jerry, I have the long version of that Estwing, with the blue molded grip - one of my favorites, behind the Norlund with her proud nose...

"The square leading edge"...

Greetings. Fascinating.  What are your hole diameters? Thanks,

Robert Taylor

Just as a point of observation:  It is much more challenging to cold work this stuff with a hammer than on the press.  With a hammer it wants to throw the hammer back at you, rather than deform the work...

Jennifer, thanks. This is Do-All commercial bimetal bandsaw blade.  Very springy spring steel.  I have two sizes of band:  18' x 1.32" x .044", & 18' x 1.062" x .036".  This chisel is formed from the .036" material:  

This is at about 150 - 200x magnification.  I believe we can see some work scoring but not cracking.  If anyone sees a crack, let me know.  I am sure that under sufficient magnification, some compromises will appear:

I think one would expose stress cracks at the mushroomed zone.  If I recall correctly, this stuff is more prone to cold cracking perpendicular to its length...

This 4" long chisel is VERY rigid under offset hammer blows...

If anyone wants to play with a bit of this stuff, PM me.  Expect a bit of shipping delay though...

I like New Mexico quite a lot.  My Uncle Robert was a scientist thereabouts, you know the types who hang out around Albuquerque...

Edit: A geologist, now that I have pondered it...

However, the ability to change spindle speeds would have been nice.

You have three forward speeds, and three in back gear, and pitch guide on the half nut?

My little southbend has 3+3.  One of these days, I will put a variable speed drive on it...

Thanks, all! Yes Jerry! I like to lie down when greeting many of my furry friends. I have ony known one goat - I expect to see him too.  He had a very odd name - Billy!? Go figger...

Thanks again, IFI family...

Update:  Cousin Phyllis is home, recovering, but exhausted.

Had to have our Kitty, Coco, euthanized today.  A truer Friend and Companion for eight years, one could never have.  Thanks IFI Family, y'all are the top of the top.

Yuck.

Welcome from extremest of southwest United States, in the hills of San Diego county, California. As previously stated, good idea to contact New Hampster Blacksmiths in your locale, and Welcome to the madness...

Scott, I am too tired to try to protect my presumptive intellectual property.  I have a younger brother who stole most of the good DNA, and he he has many patents, and shares our 'open source' philosophy...   all good.

The 'quick change' on the pictured chuck, is in that one can simply pull one ball off, and throw another size on.  This one has an accidentally pleasing range of about ø.5" - ø1.0". I have a worked out a hyperbolic curve for a wider range for a single chuck. That is, a curvature that grips various ø balls with adequate force. I have a very competent grinding machine to achieve the desired profile. It is all savantry at this point, and requires further proof of concept.

I'm more likely to steal the method of mounting the angle iron for use. 

Very handy, Thomas.  We always wish to weld up a proper fixture once we have proven our concept, but one reliable Blacksmith's addage, is that prototype and mockup often become the finished product.  Nonetheless, this is one item well worth fabbing up, as a floating flypress V-block is a thing delightful, indeed. And SO simple to fabricate...

I suppose I ought to produce that batch of pudding...

that he rigged up a rotary table to hold dies for it and change them out *fast*.  IIRC he was using a differential for the bearing and a thick plate cut in a circle with the dies mounted towards the edge of it.

I would love to see that...

The Lathe is also a GREAT Milling Machine

Yep, built a little cross slide milling table for my little Southbend. It is said that one cannot turn with a mill, but can mill with a lathe...

Malleus, did you Logan come with change gears for screw cutting? Lathe very Pretty!!

Robert Taylor

Cold forming commercial bandsaw blade as a hammer eye cleanup chisel.  This eye had a lot of big chunks in it.  Works well.  Magnetic ball chuck holds different sized balls.  I am sure someone will steal my idea, or, am I unwittingly stealing it from someone else? Oh, the Mystery!!

Robert Taylor

Latticino, they busted a larger bullet right at the moving jaw, at one of my previous workplaces.  Pretty sure I know the "special supervisor" who probably broke it.  I pulled the two pieces out of the dumpster.  Someday I will gouge out the break and restore it.  

Where is them Logan pics?!

Robert Taylor

Ooooh, I have operated a couple of Logans, they got the job done! Was offered one for free, no place to put it.

Pictures! Pictures!!

Robert Taylor

P.S. - nice restore on the Wilton.  pm for shipping address...

Nice, Frosty. I use iron tie wire as you have described.  Works quite well. I just checked, and I was able to one hand a bowline on the bight (keep a length of rope next to my recliner, because a member here likes to teach me knots over the phone).  Half the time in the field I can not do it to save my face...

Have yet to forge weld any wire rope.

Edit:  been a few years, Thomas?

Wow, following now.  I have two pages to catch up on...

It seems that I am not alone in having multiple stashes of stock.  I am on a mission to sort and consolidate my horde, but have MUCH work to do...  Thus, here is a small sample:

One of numerous stashes of industrial grade bimetal bandsaw blades 22 years of collecting...

One of two old school Lyon stock racks...

Second rack needs some body work, as the fork truck operator was having a bad day...

Glad I hit these with a bit of Rustoleum ten - fifteen years ago...

A LOT of sorting and consolidation ahead. Forgive the redundant comment, I want to remind myself....

Alas, my ADD will not let me read through this post in one bite.  Thus I will respond to the utility of the "limiting principle", as pertains to my former line of work.

In reference to that paragraph, many of my colleagues relied upon the former.  It was easy for me to rely upon the limiting principle, based upon the assumption that every decision in Aerospace is presumably a matter of life and death.  Very inconvenient.  many have learned by encountering me in course of our duties, that I valued my employment far less than the altruistic demands of the Hardware, and those subjected to its end use.

I had many customers, the last gig was for a three acre footprint. In my trade, it was easy to be intransigent about the processes within my view.

How much harder it must be to develop and stick to limiting principles in your line of work, I would think.

You are the fellow who sold me on the difference between Accuracy and Precision, by the way...

Robert Taylor

I have one of those, made in Taiwan, and it is Good Iron. Love that swivel.  Lots of inferior clones flooded the market, it seems. Got one of those in two pieces, rusting in the yard.  My other three bench vises are U.S. iron...

Pretty far off the subject of blowers leaking oil, eh? Lol.    All good — someone will bring us back around. I like hearing everybody’s experiences. 

I fear that unless the OP returns with an update on his blower, all may be lost...

I put my pole spike into my opposite foot below the ankle a couple of years ago, so I do not think I will be revealing any of my tree stories to Mr. Yanni.

I can not come close to the shanti of Captain Ahab of the Great White Birch...

Sometimes I am gone from this site for weeks.  I had eight or ten of these fall into my lap a few years ago.  Ground a bunch of the spikey bits from one, to use as an eye drift.  Just as tough into the meat, as it was just under the chrome.  Worked ok as a drift, but I decided to finish it on a machine (not done yet). 

I reckon these picker spindles were made via numerous methods - mine are pretty tough under the skin...
