Ebay thread dial indicator
|
Hello all. ?Have been following for some time. ?This is my first post. ?There is a 3-D printed thread dial indicator on Ebay. ?I have a SB-13. ?Will this fit my lathe? ?The add says it fits a 13, 14 1/2, 16 and 24". It looks like it is plastic. ?What do you experts think? ?Thank you.
|
I'd trust the listing for that, although that's certainly a wide range of lathe sizes for one item.? If you can share the link we can take a look.? You can probably get it cheaper if you find the model and have a service like shapeways print it and mail it to you, but it may not be a big difference in price.
You can also buy a perfectly nice 3d printer for around $150-200 these days, so consider that the part might be a significant fraction of the cost of a plug-and-play printer (e.g. a Bambu a1 mini)
I use a 3d printed threading dial on my 10k and it works great! I had a friend print the body and gear at 100% infill, then I turned a brass dial and press-fit that on a shaft.? I sanded the plastic parts, primed, and painted so it matches my lathe.? You can see the finished version here: ?

That Bambu a1 Mini is pretty remarkable, especially at $200. Thanks for the post. Your threading indicator is first class.
My history with 3D printing goes back to the early '90s, shortly after 3D Systems introduced the technology at $250k per machine. Jumped back in with a $2k machine three years ago that also had a laser head for engraving/cutting. Material choices with it were limited, and surface finish was nothing like the Bambu! (Commercial production machines still go for multiples of $100k, of course.)
Viva innovation!!

Whether it fits or not assumes the seller made it correctly. As far
as if the same part fits all of those listed machines, you could
probably verify that yourself by looking at parts catalogs to see if
the same part number is listed for each size lathe. It would make
sense that some SB lathes would use the same part. You see that a
lot in the 9's and 10's. Unfortunately, I do not have a direct
answer.

I found a thread on practical machinist that seems to support the idea that one dial worked on a pretty wide range of lathes:? There are some folks in that thread who have made their own, although without any detail about how they got the gears...
I have *not* found a 3d model for the 13" threading dial though... The 9/10" version could be adapted, but that's a bit of CAD work.
$100 seems like a lot for a (mostly) plastic part, but given that it has bearings, and they've done the troubleshooting, it's probably not a bad deal.
There is a metal threading dial for a 16" lathe up on ebay for about the same price, maybe that would?actually work?

I did not know the price. You can find an original for that money.
The print quality does not look very good.

I don't know the difference -- I was just looking around to see if I could find something that John Grump could have printed.
If you created the model you're using, would you consider sharing it? (and maybe putting it up on Thingverse, or a similar model repository if it isn't already?)

The South Bend CE3458 Parts Manual from 1965-1966 shows that the same thread dial assembly is used on 13”, 14.5”, and 16” lathes. Here are photos of the manual pages pertaining to the thread dial.

Do you have a print for the threading dial for the model? I have a 1913 model 134 and need a dial. Looking at your pics I think I could make that work.

Hello all of you that responded to my post. I appreciate all the information you imparted. ?It will make my decision a lot easier. ?Thank you.

John, when you finally get one, let us know what you got and how it worked out. This was a very interesting thread (pun intended), despite the fact that I don't?have a 13" lathe.?
Cheers
