So the 21SC has a hple in the mast for a ginpole. The 21SE does not.

So what are people doing here? I can invent something, but would really rather build off proven experience.

Mostly, I need to know how to connect at mast and how to secure trap lines. Guessing the 80 inch length is correct for the SE as well as SC?

It's just a whole, with a stainless steel reinforcing plate riveted around it., drill it using a step drill bit, perhaps rivet some reinforcing stainless around.

It's called a compression plate. PN 30680001 about a 1/2" hole and 4 rivets. There is a seal that goes between the mast and the stainless steel plate. Watch the video on 21sc set up. Miller has some video showing the pole in action.

But my mast doesn't have that hole, so I'm left with "clipping" on a bent piece of aluminum plate to the base of the mast - the "clip" being lined with 1/4" rubber liner to keep in place and keep from scratching mast. Can't see myself drilling into the mast on the fat side, like the SC has - just kind of reluctant to add another hole.

Do other 21 SE's have a mast-stepping hole at the base of the mast like the SC's? Picked up some generic Dyneema rope to hoist it with.

I built the gin pole out of 1&7/8 Aluminum pipe, that's commonly used for hand railing. Surprisingly, it's 6061 T-6, clear anodized and was about $30 for 8 feet from American Fence and Supply. Great supply of matching fittings for the tube as well. Not cheap, but not terribly expensive either.

I'll upload some pictures later. I'm wondering how others are attaching

My mast stepper 3 has a piece that fits into the track and holds the mast sideways (Getaway masts are raised and lowered on their side), and it's held in place with a bungee wrapped around it.
Years ago, I made a gin pole for my H-17 with an 8' long 2x4 stud, cut to the side profile of the mast with rubber glued to the bottom, and tied it around my mast. The H-17 mast is also stepped on it's side. I never had a problem with it slipping. I used the traps lines for vertical stabilization tied to ropes that connected to the underbar of the front crossbar and then connected to the gin pole. I don't remember how I tied them to hold them out by the hulls, maybe a line around the front wing strut. It worked well, and cost me about $5 to build.

Thanks - however you cannot step the 21's mast from the side due to the construction of the base; it's got a notch in it for the ball to fit into, so it cannot rotate 90 degrees.

At least that's how it looks to me. The rigging I get - no problem there; it's just the connection to the mast; I think I have a solution, but would like to validate before I threaten my house with the mast in the back yard...
