    On a side note Keith, I bought a vise just like that from a biker 50 years ago. He had welded a 3/4” drive socket on the end and used a 3/4” ratchet to adjust the vise. I bought it for $15 and have used it ever since as my bench vise. It’s so heavy I’ve never bolted down to the bench. I’ve always wondered what machine it originally came off. And now after 50 years you finally provided the answer! Thank you! 🙏🏻

    Keith, when the bed returns have the mechanism hit an air valve that activates an air cylinder that pushes out the clapper box. Also, the air can blow through a nozzle onto the work blowing the chips away at the same time. As long as the bed is returning the air will activate and solve the problem.

      Or just a wiper mounted behind the cutting head. Going forward it does nothing since the tool is engaged, backwards it drags instead of the tool and wipes the chips away. Love to see old gear put to use. Lovely bit of ancient tech that's still useful.

      @@rrsteamer Not if the tool is properly ground. The idea is that going forward the cutting edge does it's work, then on the return the tool should be touching well behind the cutting edge. Same method that a shaper uses.

  • @CatNolara
    @CatNolara Месяц назад +15

    Back when Abom79 was working more with his shaper he tried some different tools and found a particular tool that produced an amazing finish. One of the main things with it was that he honed in the cutting edge while in the holder, making use of the clapper box to get a back rake. There are also special tool holders with a geometry that prevents the tool from digging in too much, making it more stable.
    Anyway, it's already looking pretty great. Could propably use it to refurbish smaller lathe beds etc. Saw videos of people in india casting lathe beds in molds buried in the ground and then machining the ways on a planer like this one with really crude looking tools, but the result looked pretty good.

    I served my engineering apprenticeship with a company called Brown & Green here in the UK which produced commercial laundry presses and equipment. The huge cast iron bases of the presses were produced in the foundry next to the machine shop and many dozens were stacked outside the buildings for several years to weather. The machine shop had 4/5 (nearly 60 years ago now) large planers in a row which machined these large bases and were all driven by an overhead line shaft. My enduring memory would be the slapping noise from all the belts as the bed went backwards and forwards.
    In those days several of the workers run their own little side lines. One planer operator was the man to go to if you wanted cigarettes and snacks, and one of the fitters often disappeared to collect a fare for his taxi business. Great days.

It was used to cut the brass bearing halves to fit within the supporting chairs for the mill rolls. I was mesmerized by the belts and operating mechanism whenever it was in use. Aloha!

    The cutting tool dragging on the surface during the back stroke isn't really a problem. Because the machine is feeding at the end of the cutting stroke, the tool will drag on the not yet surface. So it won't leave any marks.

    Sometime during the 1960's a friend of mine worked at a machine job shop which made o-ring molds which were 2 plates about 1" x 24" x 24" . The rough p late was machined flat on 1 of 2 planers which were twins to yours. They were mounted on very short legs , probably to simplify handling of the plates.

    Check out the older Machinery’s Handbook foot cutting tool shapes. Roughing was done with tool that you have. For flat finishing, a broad flat edge cutting tool was generally used. Scraping by hand followed. With the flat edge a relatively flat surface can be machined with a very corse feed. The original surface of the platten or table would have shown this type of feed. You’ve done a nice job of rebuild. Be sure you show oiling all the points needed to be oiled, as most folks don’t realize how much lubrication is required.

    @generessler6282 Месяц назад +1

    Hah! As to horizontal surfaces, it's not just in shops! This is a continuous (44 years and counting) discussion with my wife! Love the old machines. Fwiw, Abom79 has many episodes on his big shaper that has a similar clapper box. He talks about how the angle of the clapper pivot is super important so that the tool holder swings itself out of the way on the back stroke. If you get it backward, the tool digs in and ruins things. He also points out that when you look at the setup, the correct angle tends to look counter-intuitive - like it should be thee other way. I _think_ yours is right. He dinked around with cutter grinds for a long time to get nice finishes. He uses - as you did - a specially ground shear tool and light cuts for the final passes. He hones the tool _after_ it's in the machine by putting a precision stone on the table.

  • @Container-shop-guy
    @Container-shop-guy Месяц назад +5

    Get a small magnet and strip of leather and stick it on the back of the tool holder. As the machine travels back over the work it will catch the leather and protect the work piece. Can't remember where I heard of this technique but it was the poor mans tool lifter.

    • @kennethnevel3263
      @kennethnevel3263 Месяц назад +1

      That is such simple idea to lift the tool that might have been done back in days when these machines were in use .
      The leather trailing behind the tool and then falling off the work piece before the tool returned and pushing the tool of the work on the return stroke , probably the leather would wear off and have to be adjusted down some every so often to keep it working .

    Keith, about this planer, you should look at some of David Richards videos, he has a steam powered machine shop and the music from all those belts... As someone who isn't a machinist, old steam powered machines have always been my interest over electric powered. However, since times have changed, I do agree with you adding that electric motor to your planer. But, nothing will beat the old steam powered in my opinion. I know many today prefer speed but, I'm an old school type of person and sometimes, slow is the better way to go. I've seen what high power and sped up work can do, I've also seen the carnage that happens and the cost of said failure vs the old tried and true machines of old. Thanks for sharing, great video as always, cheers :)

    I can relate to the "Probably should have scrapped it" comment! Not because I think it should have been scrapped, but because I've done the same thing! Many years ago I "rescued" a car that was going to the crusher the next day if my friend didn't get it out of his parent's driveway. I paid him $100.00 for it. 1971 Camaro, half missing (no engine or transmission, etc.). Over 25 years I collected parts and "Restomodded" it and wound up with a NICE street rod! To me it wasn't about the "finished" project, but the journey along the way!

    As you have got straight cut gears, I’m not surprised there is a bit of chatter, but the surface finish looks really good. The main thing is a flat surface finish.

    To think that the Civil War was mid 1800's and then the tales of cowboys and Indians, Custer's Last Stand, and a handful of years later someone is operating a machine like yours and producing items improving America. We need manufacturing brought back into this country and we need it now. Vote early and take ten people with you.

    I love the sound it makes. I'd like to see the straightedge blued up on the surface plate to see how flat it's coming off the machine.

    Hello Keith, Love this video. I have a SB &" Shaper. finding the right tool for the best surface is a challenge, at least on my shaper. I would suggest some diamond lapping disks to sharpen the edge. It worked on my cutters (mostly HSS). I'm looking forward the project that will be cut down to size with this planer. KOKO!

    a simple way to patent an automatic clapper lift on the reverse stroke is to use the pneumatic in your shop, a cam activated pneumatic valve and a Bimba or alike throw away pneumatic cylinder, you use the belt shift mechanism to trigger the pheumatic valve and the pneumatic cylinder to lift the clapper on the return stroke.
    There is many ways to engineer the support brackets for the valve, the cylinder and the lift le block ) but in any ways, this can stay very simple add on.
    One thing I observed is that the feed distances seems to be very agressive, this can explain the shattering you observe on the finished surface on the machined part.
    very interesting machine
    very interesting video.

    CARBIDE WOULD BE BETTER FOR CAST IRON DUE TO THE AVRASIVE NATRUE OF CASE IRON. GOOD TO SEE THE OLD MACHINE WORKING. STILL USEFUL TO MAKE A FLAT SURFACE ON A LARGE SURFACE.
