    Monarch AA - Cross slide removal

    Here's a picture to help. Also let me know if this should be in the antique forum instead.

    Monarch AA - Cross slide removal

    Anyone have any idea how to remove the cross slide on a Monarch AA? I have the taper attachment so I can't remove it from the back. I just need the feed handle block removed so I can pull it out the front, but there's no bolts or anything holding it on. I stuck a small wedge (read: screwdriver)...

    My new Walker Turner Drill Press

    Sorry, I just reread my post and realized it was accidentally misleading. The drill press as a whole is about 1,000lb including the table. Not that it makes much of a difference. Looks like you lucked out with an abnormally understanding wife! I think mine might have a few words if I told her...

    My new Walker Turner Drill Press

    I've got good news and bad news. The good news: Just got this drill press and I'm pretty excited about it. The drill press has to weigh close to 1,000 lb, but check out that cast iron table. I've never seen one like it and it's got Walker Turner cast into it so I can only assume it came with...

    Old Yale and Towne Chain Fall Clutch Disc

    Leather breaks work well. Just make sure they don't dry out. Give them a drop of leather oil now and again. Almost any type of modern friction material replacement will work as well. I've even heard of people using bronze brakes... but I have my doubts about that. However be careful with your...

    Old lifting mechanism of 1770s

    I agree with Asquith about the reasoning for the arm. Maybe the unloaded side of the arm could have had a guy rope tensioned to the bottom of the column to help to transform some of the tensile stresses to compressive stresses where the unloaded side of the arm would want to tilt upwards...

    Old lifting mechanism of 1770s

    Torque, which I'll call moment from here in since it's bending and not twisting, is feet x perpendicular pounds. The weight of the stone being lifted is perpendicular to the jib beam so the moment is the [length of the beam from the center of the column to the end with the chain] times [the...

    Old lifting mechanism of 1770s

    This is all just a guess: The material - The large diameter ties at the tope of the jib are rope. The small diameter tied around the stone being lifted is chain. Structure looks wood. The shape - It's large in the center because of the stress increases due to the large hole to support the...

    Monarch Model AA (?)

    Thanks. Can you confirm that it's a Model AA? Also do you happen to know if I'm able to look up this serial number/lot number to get the year or info on it?

    Ah hah! Ok let me try this again. Are these pictures better?

    Monarch Model AA (?)

    I know! There's a 19.5kb limit on picture size so I'm not sure how to make them bigger?

    Monarch Model AA (?)

    I'm not a machinist, just a hobbyist who likes old tools and sometimes spontaneously buys things when the price is too low to pass up. I bought a Monarch lathe the other day for $50 out of someone's garage and figured I had nothing to lose. I think it's a Model AA, but if someone knows otherwise...

    What kind of shaper is this?

    Here are some pictures. My handle for the feed broke off when I was unloading it originally and I have yet to fix it so mind the parts lying there in the picture. Let me know if there's something specific you want a picture of.

    What kind of shaper is this?

    I actually already own it. I bought it the other day for less than I could scrap it for so I figured I had nothing to lose. Impulse buying at it's best! I was just curious about the origins, but it's seeming more and more likely it was custom made at a school or someplace. Maybe a Frankenshaper...
