Well done on the spinner - a real challenge at that size using curved strips. You have good eyes!

Sorry to be so late to this. especially after you doing such a nice job, but have thought about vacuum forming the spinner? It is my goto for spinners because of the room you have.

Secondly, is there a chance you could post the plan in the plan section?
I have not seen this plan and it may qualify for the Guillows Challenge.

I have not yet wanted to take the plunge with vacuum forming my own spinners/canopies/cowlings. With respect to the plans,the impression I got, and I could be wrong, is that any currently manufactured kit's plans were off limits to publish in the plan section due to copyright infringement. If anybody can validate or refute that please step up to the plate!

 I found this via google search:

My understanding is that Guillows have agreed that pre-1970 designs that are no longer in production can be posted publicly (which is why the Plan Gallery specifies    
Guillow's PRE-1970s   Vintage and Out-of-Production ONLY)

So check with the Guillows web-site what they have on the current production list.  Just because someone has it for sale isn't necessarily an indicator of current production - there is a lot of NOS still around.

the reason I ask is because the 50-2 Kit has not been in production for some time and a lot of the 50- series of kit plans are allowed in the 100th anniversary  contest. The current production kit 903 can purchased on their site. Sorry if this has led to a little confusion.

It is basically the same model but maybe with a few additional drawings on the older version. Anyway, I uploaded it. It is a very old plan and in very tattered condition. I uploaded it as 8 images. 4 on the front and 4 on the back. Just have to wait for the administrator to validate it and post images.

Thanks Marc

Looking forward to seeing the plan. I may try to stitch it together and repost it, if that is OK with you.

No Problem.

The third time might be a charm.  What can I say, I am the ultimate masochist. And before you ask, no, I am not yet interested in trying Vacuum forming. Call me dimwitted for doing things the hard way! Actually, at this point, I think that vacuum forming might be a lot more involved than this experiment that I am trying. I ordered some small  diameter springs from China off of E bay. So, the unit will be even more compact.  I will also sand the thrust button to a smaller diameter to fit inside of the new spinner. We'll see how this one goes.

These are the springs that I ordered: https://www.ebay.com/itm/145770205872?var=444867652490. I am going with the 2mm diameter. Just enough to fit around the brass eyelet. I think that I might also go with basswood for the prop blades and hub.
