I recently bought a Rockwell 3400 lathe and trying to find out if I can get a drilling attachment for the tail stock.
Someone told me the live center in the tail stock could be taken out. There is a hole in the end shaft and I put in a screw driver (small) to drive out the I believe you call it live center but it won’t budge with an good hit from a mallet. Don’t want to break any thing so didn’t wack it too hard. Could it be a one piece? or will it come out? Very small hole (1/4 inch maybe) and I don’t have the original knock out bar for it.
Do I dare put a propane torch to heat the outside up a bit?
What do I need to be able to set it up to drill holes in something I have turned?

It has a MT1 taper in the tailstock, so it’s probably just stuck in there pretty good. If you don’t want to beat on it while it’s in the tailstock, you can eject the quill and try working on it in a vice or something. I wouldn’t use a screwdriver or anything made of hard steel, as it might damage things. The headstock should have a 7/8-14tpi thread, so I would suggest getting a tap to make your own faceplates, threaded glue blocks, jam chucks, mandrels and other stuff (can all be done with scrap wood for cheap). Drill chucks for the tailstock can be found all over the place for not a lot of cash.

Cheers,
Brad

Thanks Brad. I am from Canada so not sure about ordering from Penn due to customs issues and shipping. Going to try and find a rod that fits and hit it firmly after pouring in a bunch of wd40.
Ordered some face plates but they wobble real bad so leveled out the plywood but think I should have used solid birch for faceplate.
Going to try your idea of a wooden hub and face plate. The threading will be tricky but will give it a shot.

Hi Vic. Drill chucks can be had at Lee Valley and Busy Bee. However, a lot of Beaver lathes had fixed dead centres in the tailstock. If that’s the case it won’t hammer out. You could try taking it apart to find out. Go to Vintagemachinery and look under Beaver for a manual and parts lost. Maybe put up a picture of your tailstock. Also Canadianwoodworking.com has many threads on that lathe with lots of knowledgeable people to help. Cheers

The tailstock has a 3/16 hole in it so I thought it should come out. Here is a snapshot of it.

It comes out… here is the parts diagram:

Diagram can be found at the VM site.
Pretty sure they shipped with both a live and a dead center. Yours has most likely been in there for quite a while, so it’s just being stubborn.

Cheers,
Brad

PS: The drill chuck I linked to was only to provide an example of what it looks like… you can get them pretty much anywhere, even Canada :)

Hmm. Does the large end turn independent of the spindle? If so that is a live centre and it is, indeed, stuck. Lots of things to try. Wd40, heat and sometimes putting in the freezer overnight. Try not to hammer to hard or you will risk mushrooming the end. Good luck and let us know how you make out.

Brad are the taps for 7/8 by 14 readily available?
Yes the large end turns freely it has a bearing in the hub.

You can get them all over the place… at least here in the US. A quick search shows that you can get them from Amazon in Canada, but can probably find one cheaper at a local auto parts or hardware store… just look around… I don’t really know what kind of sources you may or may not have up there, and it doesn’t need to be anything fancy – just plain steel works fine (that one on Amazon is HSS, which is nice but not necessary for wood).

Also, forgot to mention – about using the tap… it’s super easy to do. Take a scrap piece of wood (I can get gobs of scrap 2×4’s out of construction site dumpsters for free) and drill the appropriate sized hole in the middle of it. Doesn’t have to be perfectly up and down or centered, but try to get it close. Once you have the hole drilled, run the tap through it. It will thread easily – it’s only wood :) Once you get the hole tapped, screw it on to your lathes headstock and true up the face and make it round. Then flip it around and do the other side. Before you know it, you have a threaded glue block. Or glue on another piece of wood, and turn it into a jam chuck. Or drill a hole and put a bolt into it to make a great mandrel for turning wheels and stuff like that. Or make it a cone, which allows you to put a pipe between it and a center on the tailstock for polishing. Lots of possibilities:

The blank on the lathe above is glued onto a wooden faceplate/glueblock and threaded onto the spindle. It later became two lidded boxes :)

Brad

Wow thanks will check home depot to see if they have taps.

Have your say...
