Since i don't have 3 hands, i will post some pics with commentary on how to put a swoop in your cab,or "inside curve" as Tommy says. i will post the pics in order. 3 things to remember 1) Be patient 2)Dont hurry 3)Slow down... lol i always start with a template shape,i have a few favorites, but they are all modified,to make them just a bit different. i don't like the same old cookie cutter(stock) shapes i am always trying to add a swoop here a curve there or a nice arc. when i find a basic shape i like? i play with it until it is pleasing to my eye.  IMG_0006 by paul forsythe, on Flickr the inside shape is the template,the outside lines,make it my own  IMG_0008 by paul forsythe, on Flickr i take it down with the 60 grit as close as i can...great on jasper, carefully with soft stuff,you might want to go up a grit or 2  IMG_0010 by paul forsythe, on Flickrhere is the key to the swoop,hold your preform to the wheel at just below,or at 3 o clock,till it is formed to the arc of the wheel,this is an 8' with a 6 you would get an even mor pronounced curve  IMG_0017 2 by paul forsythe, on Flickr here is the back,you can see the shape forming  IMG_0016 2 by paul forsythe, on Flickr i flip it over and start my dome...still on the 60 ![]() http
s://live.staticflickr.com/65535/50711577853_34e5d34b77_c.jpg[/img][/url] IMG_0021 by paul forsythe, on Flickr i finish the dome on the 100 hard and go down the line to get all the scratches out and polish it up  IMG_0062 by paul forsythe, on Flickr as you can see the curve is not super pronounced, but it gives an elegant look..to me at least  IMG_0051 by paul forsythe, on Flickr one more pic..and there you are...i tried to post this in tutorials..with no avail...i am happy to answer any questions. just to let you know...i make it all up as i go along. if it feels good? do it! |

Thanks for the pictures and descriptions Paul. The inside curves you put on your cabs are truly elegant and pleasant to the eye. I really dislike doing them because I struggle with the girdle on the inside curve being a bit higher than the rest of the cab. You make it look easy!

Sweet! That's about how I do it, too. I have 6" wheels.
Only mods can move things to the tutorial section. I'll move it after it has had some time here.
LOVE the cab, BTW. And, thank you for doing this.  |

I can't compete with the swoop king. I do have a few remarks.
I mark a girdle line on the swoop and grind to it the same as any edge. When making a freeform it needs to be pleasing to your eye. I grind to the back and the top to see the full arc and adjust the top and bottom to it. The six inch wheel makes a deeper curve and the other sides need to meet the end points of the curve.

Paul - thanks for posting the tutorial on this. I know there's been lots of questions regarding how this is done. I've done it with my dremel, but the only way I think I can do it with my slant cabber is to remove the splash guard...

You'll mangle your laps if you try doing this on your slant cabber. |

You'll mangle your laps if you try doing this on your slant cabber. Not just the laps, I'd mangle my fingers! LOL I learned my lesson from the first time I used the cabber and miket's recent fiasco... I really wouldn't have tried it on the slant cabber...just "thinking outloud" on how it would have to be done on one...  Seriously, thank you for confirming it being a "no-no" for me though. |

Really great description, @hookedonrocks (Paul)! The proportions and shape of your concave example here are really attractive. You know just how much to carve out of the stone. I have most difficulty polishing the inside of the concave shape. Not trying to ninja this thread, here is a shot of one of my very early attempts at this, from over a year ago. One of my first cabs, I think I stumbled upon this shape by falling asleep at the cabbing machine, pushing the stone in too far.  Here is another shot. Hopefully it can be seen. This was during my experimental bails period, and so take it for what it is. I was using the concave spot to bring motion to the stone, and used wire wrap to express "flames" in the rock. I wish I had some of your nice Ocean Jasper to work with at the time.  Thanks for sharing your technique. I am going back to read now just in case. |

I really dislike doing them because I struggle with the girdle on the inside curve being a bit higher than the rest of the cab. You make it look easy! I have a love-hate relationship with these. I love the results and the challenge, but, yes, the girdle can be frustrating, as there are a lot of factors to juggle. I’m getting better, though — mainly because I have slowed down. |
