The pictures that follow are mostly taken in my garage where the forklift unloaded the machine.
Pulley and carrier cylinder. You see TD, RK knew what he was talking about, an industrial giant, not a midget! Dovetail ways and shims. If that keyway is not milled ahd from one end to the other it could be a feature also preventing the quill from releasing.
Overall view of the spindle. The hardest surface it should touch off the lathe is wood.
Plus, those beaver marks will be assemly and remind everyone who sees them a hack has worked on this machine. Bookmarks Bookmarks Digg del. It weighs 60 pounds as shown. Also, I have not called Leblond but I am aware that they still sell some parts.
To cut those radii for the threaded antirotation holes you kind of need one- plunging with an end mill is the way to go. You may use these HTML tags and attributes: Thanks in advance for any suggestions. I applaud your asking these questions. The ram simply screws in from the front of the tailstock. The hole in your lzthe for the pin of the wrench has been damaged by folks doing it the brutal wrong way with a drift or screwdriver used as a punch.
It’s used as Bill described, extend the quill until the eject slot is fully exposed, insert the drift until it stops and a light but sharp rap with a light hammer will disengage the taper. I’m pretty sure that LeBlond still supports these newer machines but when you get the price you will probably decide to make it yourself.
I keep subtracting these weights from the estimated total ofhoping to end up with nice small numbers for the bed and cabinet so I can roll them downstairs into my machine shop with a Yates appliance dolly.

I pretty much did the opposite of what I did to take dismantlijg apart. Parts 34 and 35 appear to engage the quill somehow. Funny how regional colloquialisms can creep into language, even funnier when one tries to convince others that a large machinery company, dated far earlier than he, therefore closer to the origin of the word, isn’t as well versed in machine nomenclature as he is!

The cap bolts are standing on the way surfaces. I could finish cleaning and installing the lathe and just make one, but as I said I’m inexperienced. It slides out easily after its off the screw. I can not tighten it dismsntling a snug fit between the center and the stock piece being turned. Here’s a quick link that shows what we’re talking about.
I am sure there is further adjustment required here. Check Mc Master for the nut. The bracket that holds the tailstock to the bed is trivial to remove.
I was hoping that someone could instruct me in the recommended way to dismantlibg the spindle itself from the tailstock and the nut from the tailstock spindle. Rear view without gear box. The nut itself 22 appears to be held in by two hex screws, but I’m not sure if the nut itself is threaded on the outside and screws into the tailstock spindle, if it is held in place with some sort of adhesive in addition to the screws, or if it is pressed in.
Reassembly was also quite easy. I could also be completely wrong Usually other confounding clues can lead you to some more understanding of the construction.
