Great discussion. I remember a discussion I had with John Wright, Sr. about slab vs split. He and I both agreed that a slab elevator with 13° of up travel works great, and we weren’t sure why folks went to the expense of converting to a split elevator. I have to admit it’s sexy, and if your gross weight is over 1320 pounds then I would guess it’s much more important. I have nearly 2000 landings in my C model, and of all the mistakes I made, none were related to running out of elevator. My experiences are limited - thoughts?

Thank you everyone for your help. I search the website but I can not find the film index. Can someone direct me to it?

Larry, you are correct re the owner produced part. There should be no problem having the dwgs.etc. I remember hearing the late Bill O'Brien FAA Washington talking about the reg as he was pushing it thru the system - he wrote/reviised a number of regs with the field folks in mind. This issue is one of the reasons {vintage) the reg was written He stood in front of the audience and commented that the "owner" had to be involved in the process and with "tongue-in-cheek" he said the owner could be the final "QC inspector" in the process.. He was a great guy- very approachable - I had several interactions with him. The FAA has an award in his name. FWIW

if you go to the Ercoupe drawings 415-22001 film index A562 is assembly elevator.Film index A564, A565 and A566 show further details of construction. there is prior chatter on the mail archive section. The drawing for the split elevator is 415-200010 I believe. John Cooper said Skyport had the factory drawings , but Lynn Nelson said 'Yes John, It is possible to convert your straight elevator to the split one. The only pieces you use from the old one are the front beam (spar) and the end ribs. Everything else is different. I obtained a drawing several years ago and converted one. Since then, I have converted several airplanes, and I recommend buying one already made and rebuilding it vice trying to remake yours. I admit that I am slow, but making the ribs (only two are the same) and all of the skin pieces (six) takes me several days working all day.
If you do not have the tools to dimple the skins, and make the offset trailing edges it is really tough. (Unless of course you have access to or a friend in a metal working shop). Unfortunately, you cannot go to the local Sears Roebuck or hardware store and buy the tools and materials.
Please ensure you have approval prior to making the change. It took me several months to convince the local FAA FSDO that it could and should be done.
