  • Grizzly 10X22 Lathe - No Collet Closer Available

    Folks I was looking at the Grizzly G0602 10X22 lathe which has a 1" spindle bore. I wanted to use 5C collets with it but they do not offer a 5C collet closer nor does Royal Products. What, if any, are my options in regards to using 5C collets on this Lathe?

    I believe 5C requires at least a 1 3/8" spindle bore to fit, so "native" 5C is probably out.

    You could perhaps make/buy a 5C collet chuck to go on the spindle nose. See http://www.workholding.com/BISON-SUP...ADJUSTMENT.htm

    Metal Lathe Accessories has a casting kit to build one: http://www.statecollegecentral.com/m...the/MLA21.html

      If the bore in 1" and the 5C collet diameter is 1.25" you'd need to build out a new nose on your spindle. That doesn't sound like a compatible machine for what you're after.

        It doesnt have a taper in it from the factory? Perhaps a MT3 or MT4. My HF 3 in 1 has a MT 4 taper with a 1 inch hole. I got a set of MT4 collets cheap off e-bay .

          What does that leave you for hole size when turning long stock? This is a factor when I get ready to replace my little 3 in 1. Mine's an MT#3 taper so not a candidate for this solution but still a nice little (challenging) lathe.

            You could use 3C or 4C collets. 3C will be more abundant. Guessing the headstock must have a MT4 taper in it so you will have to find or make an adapter. Then make a drawbar.

              If you don't already have the 5C collets, have you considered setting up for ER? Fairly simple to make the adapter and you don't need a drawbar.

                Thanks everyone for the great responses. I was told by another machinist that since the lathe had a 1" spindle bore I should use the 5C collets. I don't have enough knowledge about any size collets to know what will or will not work. The lathe has a #4 MT in the headstock spindle so what setup would be the easist for me to get into assuming I go ahead and buy this lathe.

                Thanks everyone for the help, I really appreciate it.

                  Bill prescisely what would be required to be able to use ER collets. I am not a machinist, just an old man who is trying to get into the hobby and is having to learn everything from any source I can get it.

                  Thanks,

                    I would think you would be happy with a Bison 5C collet chuck. I like mine and even tho my spindle is 1 3/8" I don't think any 5C collet over 1" lets the stock go tho anyway. (at least mine doesn't) I have the Grizzly G4003 with the D1-4 camlock spindle (mt5 bore)

                    www.littlemachineshop.com has a 5C collet chuck and backplates, I bought mine from KBC a few years ago.

                      The only way to get 5C collets to be fitted with a through adaptor that allows the full size stock allowed to pass through the spindle on the 10x22 mentioned is to make a completely new spindle IMO. The Grizzly pdf of the parts amnual lists the front and rear bearing as being 45x75x20mm. That makes it a 209/6209 or possibly a 7209 in it is an angular contact.

                      To go with a larger ID bearing which would be needed as the 45mm bore is 1.7716" this would leave a wall too thin especially as the spindle looks to have the center section cut down for clearance. Going with a 100/6100/7100 series bearing might be problematic as there might not be a size that would fir the bores. A better option might be to source a Tapered Roller Bearing. There should be a cup and cone combination that should fit the bore that would have a large enough ID to allow the internal bore. This is one thing a have a hard time figuring out why the lathe manufactures in the Far East haven't built a small hobbiest lathe that has an internal 5C Collet set-up built right in. I'm looking at doing this very thing myself on my lathe (PM1027)as I have to admit I really don't like the idea of the amount of overhang from the front bearing that the 5C Collet chucks present.

                      Having checked on bearing sizes (man I miss the manuals I left behind when I retired) the bearings are 100 series bearings. To go with larger ID bearing one would need to go with ultra light bearings. Not cheap.
                      Forty plus years and I still have ten toes, ten fingers and both eyes. I must be doing something right.
