Updated: 2/23/2024. Over time I have decided that I STRONGLY prefer the SC2 chuck, rather than the SC1. I would NOT purchase the SC1 chuck again!

Why? If you are only going to get one then I recommend the SC2 chuck. The jaws open further. Thus, it has bigger internal and external grip range.

I really like the new Record Power (brand) Mini SC1 & SC2 4 Jaw Scroll Chucks. I have and really like both chucks.

If you are only going to get one then I recommend the SC2 chuck. The jaws open further. Thus it has bigger internal and external grip range. See chart below for SC1 & SC2 grip ranges.

On 3/10/2023 the SC1 & SC2 chucks are a great deal at $100 each. I think this may be just a low introductory price. I decided to get in on the ground floor of a good thing.


Record Power SC1 Chuck

I recently purchased a "Record Power SC1 Mini Geared Scroll Chuck" at Christmas time. A present to myself.

I have really grown to like this chuck in a short time. I have been thinking about turning some weed pot examples for my students and this chuck really excels at small things. It tightly grips things like a big 4 jaw scroll chuck.

The wrench is a little weird. But, it works no problem. It needs to be weird to fit inside of a chuck body that has been scaled down to be just 2" in diameter.

I have shown it to several people and they really like. Thus, I decided to put it on my blog.

I actually agree with the sales hype on the Highland Hardware web site.

– The SC1 and SC2 are the first mini-chucks on the market to offer woodturners a premium-quality solution for those who regularly turn small, intricate items.

– It has a very compact 53.5 mm (2”) diameter body – giving easier access around the work piece making it ideal for the turning of very small items.

Record Power SC2 Chuck

The SC2 chuck is a little bigger (2-1/2" diameter body) than the SC1 (2" diameter body) chuck and looks more like big 4 jaw woodturning chucks. I never really considered it when I purchased the SC1.

I decided to purchase SC2 chuck while the price was right. I may need two chucks for my students.

I like the SC2 chuck better than the SC1. Why? I really don't known. Probably because it looks more like the big 4 jaw woodturning chucks.

The SC2 chuck also has a weird little wrench. It is NOT the same as the SC1 wrench. But, it works no problem.

If you are only going to get one then I recommend the SC2 chuck. The jaws open further. Thus, it has bigger internal and external grip range. SC2 internal expansion mode is 13/16" to 1-5/16". SC2 external compression mode is 1-1/8" to 2". See chart below for SC1 ranges.

Note: I have one of the smaller Barracuda2 chucks by Penn State Industries. That damn chuck drives me crazy. I have to fight with the wrench. When you try to tighten the jaws the wrench pops out of the hole. Err… The Record Power SC1 & SC2 chucks are definitely better quality then the Barracuda chucks. No problems with the wrenches. They cost less!


Jaws for SC1 & SC2 Chucks

The SC1 and SC2 chucks use the same jaws.

The standard jaws are really nice. They have a little lip on the inside top that really grips a tenon firmly.

The dome jaws are good for finials. Check out the YouTube video below. I DO NOT own the dome jaws. Thus, I have not tried them.

Chuck Size Comparison Photo: Chuck Size Comparison (sc1_sc2_chucks_04)

Chuck Body diameters: SC1 = 2", SC2 = 2-1/2", SC4 = 4" , Stronghold = 4-1/2".

Note: I do not own a Record Power SC3 chuck (3-1/2″ body diameter). Or a Oneway Talon chuck (3-1/2″ body diameter). If they were in the above photo they would fit between the 2-1/2″ SC2 chuck and 4″ SC4 chuck.

A standard MT2 Steb Center fits in the standard jaws on SC2 chuck. It will NOT fit in a SC1 chuck. Another good reason to get the SC2 chuck.

Note: MT2 = Morse Taper 2. Just shoving the MT2 Steb Center between the jaws of a 4 jaw chuck is a common practice that some people may not consider kosher. I do it all the time. It allows me to quickly cut a tenon on a blank that I am going to mount in the chuck, with out removing the chuck.

SC2 Chuck Example – Weed Pot

Here are some photos showing the SC2 chuck in action. Making a Weed Pot. I was able to flare the top of the weed pot with a spindle gouge. No problem. I did NOT rip the weed pot out of the SC2 chuck jaws. See last photo.

Note: NOT the wacky weed that you are thinking of! Weed Pot = A small turned vase like shape, with a small diameter hole drilled into it from the top, almost to the bottom. The vase is NOT completely hollowed out. A weed pot is used to hold and display dried plants and flowers (weeds).


SC2 Chuck Example – Finishing the Bottom of Vase

I like to sand and finishing my GREEN hollow forms and vases on the lathe when I turn them. When they are still round. I don't like to come back latter after the pieces have dried out and gone oval.

The SC2 chuck makes this a lot easier. I can turn a small 1-1/2" diameter tenon on the bottom that will fit in SC2 chuck AFTER I am done turning the piece on a faceplate. I remount the piece on SC2 chuck and put it on my air drier for a couple of hours. (See my "Sanding Wet Wood" blog entry.)

After the SURFACE is dry I can then remount the piece on the lathe via SC2 chuck. Sand it and apply a finish. The small SC2 chuck size allows me to get in there and sand easily.


SC2 Chuck Example – Box Top

Updated: 1/29/2024. The small SC2 chuck is idea for working on small things like the top of a box. It would be difficult to turn the knob on top of the box with my big chuck getting in the way. See above photo on left.

The photo on the right shows, how I used BOTH my SC2 chuck and my big chuck to check out the shape of a box. I made some changes and now all looks good. The body of the box flows into the lid nicely.

Note: My SC2 chuck is mounted on the headstock. My big chuck is mounted on the tailstock via a Oneway Live Center Adapter.

  1. Thanks Carl, I’m now using spigot jaws on a Stronghold Chuck, and for a lot of my smaller work it is a bit overkill.
    I really like that they have the 33mm- 3.5 tip spindle size available for Oneway lathes.
