Does that include the rudder and spinner?

You've got me thinking now. I'll measure it later today.

 

Edit - 97 inches rudder to spinner. Specs say 88 inches, which must exclude the rudder.

I thought it might be longer as my Sbach is 105". And I think I can just get it in the car without removing anything. You did well getting that in an A1 yes

It is lovely size model, but storage is an issue! Only room for one for me wink

No - it fits. I tried it.

Good job it's not an inch longer though.

Had a bit of time, so I've finished the exhaust mounting and cowl cutting.

Cardboard templates taped to fuselage side to mark the exhaust pipe positions.

dscn5263.jpg

.... and the choke operating rod.

dscn5264.jpg

..... and the hole for accessing the needles.

dscn5265.jpg

Exhaust pipes twisted so that the ends are not in the way, allowing cowl to be put back on and marked through the templates.

dscn5266.jpg

I'm having second thoughts about the hole for the needles......

dscn5267.jpg

...... it's not in an ideal place.

I think I'll remove the cowl if I need to adjust the needles at any time. I'm not a "needle twiddler".

Cowl ready for cutting.

This diaphragm pressure nipple needs to be ....

dscn5271.jpg

.... routed to somewhere that isn't exposed to variable air pressure as found inside the cowl.

dscn5272.jpg

This will do nicely.

dscn5273.jpg

Exhaust manifold secured using NordLoc washers.

dscn5274.jpg

Exhaust pipes connected to the headers.

dscn5275.jpg

Fuel overflow secured and routed out of the bottom of the plane.

dscn5276.jpg

Choke rod.

dscn5277.jpg

Finished cowl.

25mm grommets used for exhaust pipe and 20mm grommet used for choke rod.

Might not be so tidy if the grommets catch on fire surprise

I'll have to keep my eye on them.

Maybe I should spread a bit of cheese around the edge of the grommets to give me early smell warning of them getting hot.

I do like a bit of Gorgonzola.

I'm going to test a grommet to see if they are heat / flame proof - steady on boy dog

Nice job Gary, that's much easier with a two piece cowl yes

I would have thought the grommets would melt but you never know! I suppose the prop wash may keep the temps down.

Yes Rich - 2 piece cowl.

I'm still thinking what type of screws / bolts to use for fixing the 2 halves together. The supplied canopy screws are not really up to the job.

I'm going to give a grommet the "soldering iron test" and maybe even the "blowtorch" test before I try starting the engine.

May need to find some silicone grommets?

Looks neat, but i would prefer bigger holes myself, it'll vibrate a bit as they do, and it might set stress fractures off ?

I'll be using quite a few of them. It will also be reinforced where the bolts are. And I use bigger ones to fix the cowl to the fuselage. You might be right..
