Earlier in this summer I welded the engine mount attachments to my LEXL, E-58. I'm now wondering if should have made them bigger. They're .090" X 1" X 3" on the longest edge. This provides 1.5" welding length per side. Front and aft surfaces are welded to the station one tubes. The welding isn't pretty but it's OK. Any ideas are appreciated.

Are you planning to use the 1-1/8" tubes with the conical rubber mounts inside? If so, it looks like you will have to get creative to make them fit.

No, I have a cut Cassler so the engine mount will be bolted directly to these fittings. The rubber donuts will be on the engine side.

Your setup should work just fine.

Thank you, Kamcoman77. I appreciate your time and opinion.

Looks like it would be a good idea to have at least a scrap vw engine case to line up those firewall holes before tack welding the corner plates correct?
Thanks

Thank's at7000ft. I probably should have used the VW pattern if I ever go to a full case VW or Leonard's BS setup. I will use the setup up I now have and change things if needed. I'll use the rubber donuts on the engine end of the mount.

Terry, I mean no offense whatsoever.. but I've been mulling over the picture of that weld for a few days. I *hate* to say anything, but.. to me, it doesn't appear that there is much fusion between the tubing and the flat. I think it is too cold. It also appears to be welded on both sides, which isn't "standard practice." This is one of the most important welds on the airplane.. and it won't glide well without that weight in the nose. :)
My credentials.. I'm an A&P, which that and about $3.50 will get you a cup of coffee any more. More importantly, I've also been an EAA tech counselor since the 80s, and have inspected many projects and done many condition inspections of homebuilts. The picture isn't all that good, but it doesn't look to be an airworthy weld to me. Sorry, but I *had* to say it..

No need to apologize, Chuck. I posted to get an honest opinion and that's what you have done. I appreciate it. I too have wondered if those welds were a bit cold. Unfortunately I have since covered the forward fuselage... fortunately I have a utility knife and I am not afraid to cut some fabric. I can redo, either re-weld myself or or hire someone with a portable TIG and be done with it. Thank you, Chuck.

Thank YOU for not taking it the wrong way. It is hard to express criticism via the written word over the internet. In the end, you will be the guy that decides. I have seen someone build a nice homebuilt that was afraid to fly it because he knew every little thing that was wrong with it. Another guy bought it and flew it for years.. :) No homebuilt is perfect.
What I'm trying to say is fix everything you have any concern about. If you don't, it will be in the back of your mind every time you fly it.

I'm exactly as you describe, someone who wants to enjoy flying without fear in the back of my mind. I am mounting the fuel tank in the nose and the seventh attempt was a charm. It's not perfect but it doesn't leak and I've mounted it on rubber and will use a strap to hold it in place, so I think an eighth build won't be necessary, (I hope). I'll be posting more of my build and will appreciate your and other's input.
It's often hard to express in written words the subtlety of meaning. I've POed more than a few people on the internet by simply being too blunt.
