Thank you. I thought that it may be that way, but didn't want to go hammering away on it without a better idea of how it worked. Have a great day, Cole ... ...

So, I've never removed one and would like to! L5A, threaded spindle I think. How do you stop the spindle from turning to allow the chuck to unscrew? Anyone...
... I don't know about older Harrison lathes, but on the Myford there is a spindle lock. There is also a back gear. To free the chuck, engage the spindle lock...
I'm not sure about older Harrison's either, mine is a camlock version so I don't need to worry. However I have worked on a variety of lathes and most have some...
Do you have a threaded spindle? Many (most?) L5A's came with a taper lock L00 spindle. It uses a grooved locking ring and requires a large spanner wrench to...
Cheers for the help guys, there's no lockring or anything, or facilty to lock. We just stuck in low-gear and used the block of wood in the chuck, hitting that...
I'm considering an M300. One criteria that has led me to this lathe is that I want to be able to cut common inch and metric threads withuot having to use...
Hi Scott. Yes the M300 has a universal gearbox, so it can cut both metric and imperial threads without change gears. It does come with a spare change gear or...
I recently acquired a Harrison M300b -- the "b" is for bench lathe. I'll be running with this on a VFD. Question is -- the 2 hp motor on this appears to...

Matt, 1/4 x 20 is both Whitworth and UNC, the only difference is the Thread angle which is 55 and 60 degrees respectively. Harrisons used Whitworth Threads as...
For that matter, I"m new to machining as well. Yep - I'm a total newbie. That said, I just aquired a Harrison L6 MKII lathe and am looking for a little...
Dan, a two speed motor can't usually be used with a VFD, which requires delta connected windings to operate normally. Two speed motors usually have two...
A two speed motor will usually run happily from a good VFD. However, simple VFD's will generate a lesser 3ph voltage. i.e. if your mains is 220V, a simple VFD...
Thanks for the information - it is a little too cold here for me to be doing much in my un-heated shop (it was 2 degrees (F) here this morning. Looks like I...

Nice story Ron, and very nice lathe. I own the Harrison AA, which it the same lathe. Mine is 1988/89 vintage, in great shape. I bought it from a rigger in RI. ...
I just posted some photos of my lathe Cecil. The first four were taken in September of 1994, and show the lathe at IMTS-1994 in the REM Co. display. Photo #4...
Very nice Ron, Thanks for sharing the photos & story. Your machine & setup are very neat & well organized. I agree that this is a great lathe. I wondered why I...
