Wherefore Beaver?

Someone in Canada in search of parts has inquired which model of Beaver lathe most closely resembles the Rockwell/Delta 46-140. It is the Beaver 3400 lathe. They have inboard and outboard spindle thread sizes in common, thus faceplates and drive centers will be interchangeable. Just from looking at the photos over at OWWM it is almost certainly the case that the bed ways, headstock and tailstock of the later models will be interchangeable with the 46-140 as well. Look up the Beaver 3400 lathe on OWWM and you'll find considerable information there, including a manual that describes the procedure for removing the spindle from the headstock. The most significant difference (from reading the manuals -- I do not own a Beaver nor have I ever touched a living, breathing 3400) is that the headstock spindle of the older models from the early 50's would accept #2 MT tooling, whereas later ones were solid. I have no idea whether the spindle from one will fit the other or vice versa.

Steelex Faceplate and Spindle Adapters

I received a Steelex 8-inch faceplate (D 1088) and a pair of inboard and outboard spindle adapters (D 1096 and D 1105) as a birthday gift. These were obtained from Amazon.com for substantially less than other sources (19.50 USD for the unthreaded faceplate, 7.80 USD for each adapter).

The adapter mounts to the rear of the faceplate and is held in place by three rather small hex head cap screws. I spun up the outboard side first and turned the lathe on at its slowest setting. A slight wobbling of the faceplate was detectable by eye and by feel. Ditto for the inboard side. For the sake of comparison, no such imbalance is detectable with my Nova chuck. I shall have to spend some time with these to determine whether or not a little shimming of the adapter will get it to run true.

Busy Bee's web site says that they will ship internationally. You have to phone them however to ascertain shipping costs. I don't know how recent this development is or how expensive it is, but I just happened to notice it this evening. Anyway, at least there is a theoretical possibility that owners of the 46-140 and Beaver 3400 lathes can get parts a little more easily.

N.B. After doing a little more searching I have learned that the Grizzly and Busy Bee faceplates are Steelex brand. These faceplates and their respective inserts will occasionally turn up on Amazon and eBay and various other online tool retailers.

• 8-inch faceplate (unthreaded)
  
  
• 4-jaw independent chuck (unthreaded)
  
  
• 7/8-14 spindle adapter (for inboard use)
  
  
• 3/4-16 left hand spindle adapter (for outboard use)

I personally do not own any of the above so I can't vouch for the quality of the items. If you have one or more of these you are invited to post a comment to this article for the benefit of those who follow.

I have since acquired a Steelex faceplate. See this post.

U.S. Shipping info added 25-Oct-2010

Busy Bee of Canada stocks a number of 7/8-14 RH and 3/4-16 LH headstock accessories as well as Nova and Oneway scroll chucks, accessory jaw sets and standard Morse Taper tooling. Since the 46-140 was manufactured in Ontario it makes sense you'll be more likely to find parts and accessories there. Their web site says that they now ship to the U.S. and generally internationally, which formerly had not been the case, however it is necessary to phone them to find out the shipping costs involved.

Standard Drive and Tailstock Centers

My lathe came with an original equipment drive spur center and a 3-inch faceplate. These are right-hand threaded at 7/8-14 tpi. You'll need a 1-1/8 inch open end or spanner wrench to loosen or tighten the drive center. Apparently there was a 6-inch diameter faceplate for the lathe as well but the seller had somehow lost track of it over the years.

Also included with the lathe that I bought were a Morse Taper #1 dead center and a cup center for use in the tailstock. These latter items were also original equipment.

The above standard accessories are sufficient for turning spindles and small bowls.

An Inexpensive Entry Into Woodturning

From the questions I've answered for others in the past, I have learned that I am not alone in having acquired this lathe relatively inexpensively. I paid 85 USD for it some 7 or 8 years ago. For that price it came with a complete set of Delta chisels and a 3-inch faceplate, as well. All I had to do was drive 50 miles to pick it up. I think it was quite a bargain, considering that contemporary lathes of similar size and quality cost at least four times that much.

Why so cheap, especially since there was nothing mechanically wrong with it?

There are three limitations that seem to dictate the price:

• You will have a hard time finding or buying tooling for it because the headstock spindle threads measure 7/8-14 tpi. It seems that the lathe manufacturing industry has settled on 3/4-16, and 1.25-8 tpi as "standard" sizes for auxilliary tooling.
  
  
• The headstock spindle is solid. It does not have a Morse Taper socket.
  
  
• The tailstock spindle, while it accepts standard Morse Taper #1 tooling, does not have a thru-hole to permit deep drilling, such as one might do with a lamp auger.

In my opinion none of these limitations are or should be considered fatal impediments to buying or using this lathe because they all may be easily worked around. Subsequent blog postings will discuss these matters in more detail.
