only slightly germain to this thread, but I have an extra ER40 chuck on a? solid 5MT shank .. oh, and a lathe chuck .. about 6 or 8 inches .. on a solid 5 MT shank ... pm me if .? sorry to blunder in here, but I keep forgetting I accumulated these.? thanks.

You are more than welcome to post it. Post the spread sheet also, if you wish. I wrote them to be shared.

Re: Collets for 1922 SB model 37 15" lathe
I have the Grizzly serial number info.? I have attached the file. ?The thread is definitely 2-1/4x6.? I may have a nose insert.? My dad had purchased this back in the 70’s.? He had it torn down and he repainted it.? It was previously owned by a gunsmith.? Has tons of tooling that a lot of it we cannot identify.? I have a very good friend who is a machinist by trade and he is not sure what some of it is.? It sat for over 30 years at my dad’s in Ohio.? I moved it to Florida in early 2000’s.? I have done some very minor work with it, but it is currently buried.? I am renovating the shop and putting in storage cabinets.? I have a HF 7x12, a small Atlas (needs the drive section) and another small lathe unidentified with a lever operated tailstock, may have been used for turning starter armatures.? Again, renovating the shop so that I can get to the machines.? Also have an old B&S horizontal mill and an Atlas shaper, it too missing the drive section.? I retired 2 years ago and immediately got shoulder replacement which set me back for about 6 months.? Then family medical issues with pneumonia, RSV then covid, all last year.? Slowly catching up on normal household repairs and getting to the shop.? I have plenty of projects to keep me busy. Rick ?

Feel for you, Bro. My first class was in 1973, and only a semester (or maybe a quarter) long. Finally got desperate in 2008, and bought a Harbor Freight 93212 7x10 Mini-Lathe. Same one they carry in the stores now. Not a terrible machine, really, but I was a terrible machinist, and couldn't figure out why. Until my wife got tired of listening to whine, and told me to take another class. Started the class in February, 2015, finished in May of 2022. Should normally take 8-9 months, if you go full-time. Long story short, I was a crappy machinist because I could not accurately measure anything. There is a sense of touch you need to get the caliper or micrometer consistently tight enough to get the correct reading. I lost that sometime between 1973 & 2008. Only took a few hours sitting in class with a set of Jo-blocks and my mikes and calipers, and I had it. I've got more than one lathe, though the 7x10 is now gone, and the one I've spent the most time on lately is an Atlas TH42, which now sports and ER32 collet chuck on it's 1-1/2"x8tpi spindle. MT3 taper.? I traded the 7x10 for a couple of Unimats, an SL1000 and a DB200, which are essentially the same machine. They can be configured as either a lathe or milling machine with minimal accessories. I've made an ER25 collet chuck for one, of them, though I haven't gotten to test it. Also, I made it on the big machines at school. A Clausing Colchester 13, that being the closest thing they had to my smaller machines.? As a restoration project, there is a 1941 South Bend Heavy 10L sitting in the back of the shop, too. 2-1/4"-8tpi spindle on it. They have a proprietary insert that adapts to, in the case of mine, an MT3, IIRC. Might be MT4.? I've heard it said that the insert is about a Morse 4.5, but can't swear it's accurate. If you can get measurements of the taper, you can make all the inserts you want! Those inserts are not held in by a drawbar, BTW. I guess they're a self-holding taper just as the normal Morse Tapers are.? The tailstock is definitely an MT3, though. Steve Wells' site has a lot of the old catalogs and machine forms, so you might be able to find out more about your machine there.

Gets you the correct model number, too. Can be useful looking at those forms and catalogs.? I've not tried for an ER40 yet, as none of my functional machines can make full use of that size collet.

Physics doesn't care about your schedule.
The only reason I know anything is because I've done it wrong enough times to START to know better ? Looking for options to add collets to my very old SB 15x8 lathe.? I have seen the recent posts on using a backplate and ebay/amazon ER40 chuck.? Wondering what was the original taper in the tube of my SB model 37?? Is it morse or what I believe is SB propietary?? If morse, then I would need a drawbar and nut for the tube.? As close as I can tell the threads are 2-1/4x6, not 2-1/4x8 like the newer lathes.

??? ??? Verify your spindle threads & there is plans in the
files section to make a ER40 collet chuck . Nice thing a one piece
ER thread on collet chuck is it cut's down on the length of
stickout on the spindle & you can also feed stock through the
spindle , but make sure you have a outboard spyder if you have
long material .

Re: Collets for 1922 SB model 37 15" lathe
??? ??? ???? One thing that helps me a ton when using a mic is if
I'm measuring loose parts I put my mic in my Panavise the one with

their in a chuck on the lathe . If one half? is stable that helps
alot with the other half . While I don't have a HF mini lathe I
have a couple Craftsman 109 lathes , one missing a tailstock &

that it would make a good rotary 5th axis on my milling machine .

I think it's your chart I have on the wall above my lathe,? actually.?
Believe I bought the Vevor brand collets.?
You'll laugh,? but I needed to turn down the shank on some plasma cutter consumables while waiting for Yeswelder to ship my spares, so I put my R8 collet holder in the 4-jaw, dialed it in,? then used a collet to hold and turn them in the lathe.? It worked...

I'm also thinkin of gettin probably a set of ER 16's & that will take me down as small as I can see & then some . Are the wrenches all the same for the ER40 nuts or does that depend on the vendor ?
thanks

The Excel sheet I made up shows the comparison of metric vs imperial collets. I purchased the imperial ones. Cost more, but have size overlap the metric ones don't. The PDF is the ER40 I made for the SB-9A.

I went for er40 because I already had 3c for the SB9, and wanted to de able to hold larger sizes. When I got my SB13, it had 5C, but I decided to make an ER chuck for it anyway. ?ER has the advantage of being able to hold material that is undersized as compared to 3C or 5C.
