Cowl (cont)
Started with some wood dowel rod as risers to hold the cowl to the firewall but, after tapping the dowels, I found the wood too soft to hold threads so I got some of my red oak and used that. Some thin CA used to strengthen the threads. Tapped for button head 10X32 bolts to secure the cowl to the firewall. The risers covered a couple of the holes to secure the removable firewall to the fuse but I 'over killed' on the number of bolts used so a few missing won't hurt.
Some shallow holes drilled in risers and firewall for some 'tooth' for the hysol to set up, which will take several hours: A negative but it's very strong. After drying, will also secure the risers to the firewall with some screws. A long shank hex driver will make it easy to remove the cowl.

Removable firewall (back side).
Finished up securing engine box and to firewall using wood screws (besides epoxy).
Some sullivan easy connect ball connectors used for throttle and choke on the engine end and sullivan golden rod.
Had to attach fire wall to fuse to pencil mark outline of fuse former F-1 onto back of removable firewall to insure I don't glue the tank/servo platform where it'll interfere with F-1.
Glad I kept the old removable firewall as the sides of the platform had to be cut at an angle to clear former F-2.

Hello Sam;
I read in your comments some time ago that you thought to install as a DLE120 engine by modifying a little the cowl engine.
I see that you install the DA 85, can you tell me why you did not, because I plan to install a DLE 120 on my new project: P47 Ziroli 92'' of course !!
Congratulations on all the work you post on the forum, it is a great help for all.
Frédéric

PS: sorry for my english, I use translate Google .....

Frederic,
I figured I'd have to have a muffler custom made plus I don't think the engine will fit inside the cowl without modifying the cowl, plus I already had the DA-85.

Thanks for your reply sam;
I built my first P47 ziroli in 2005, it still flies with the 3W 80 XI, I turn the propeller 26X10 at 6300rpm. The plane weighs 14kg, it flies super but I would like a little more power. I thought that the DLE120 could be a good solution between financial budget and power ratio. I will think again.
Good construction and soon to the frequency .....

Removable fire wall (cont)
Finished up this with a removable tray for the engine ignition and battery. A large hole was needed in the FW to route the spark plug wire to the engine. Should be better for the ignition being behind the firewall versus in front of.
Some heavy duty auto FG cloth and zap finishing resin for the main gear wells.
The hole behind the gear well is for the landing light: made it removable for easier servicing and install.

ps: nice change allowing more than 5 pictures to be loaded at once on this web site!

Panel lines and 2nd coat of primer.
Took about 6 hours to lay the chart tape over the panel lines.
1/64" wide would be more scale but I use 1/32" wide. 1/16" wide was used for fake gaps ie, trim tabs, removable panels.

Doing the 'zig-zag' pattern on the elevators and rudder was the most time consuming.
Two part epoxy primer used; 2-3 coats over the chart tape and then one coat over the entire surface.
