When I built my -10, I had a very difficult time getting reasonable edge distances on the W1002 weldment when match drilled to the F1001B & F1004. For those haven't memorized the VANS plans & part numbers, these are the weldments that tie the engine mount to to the firewall / fuse.

Has anyone else had a problem with these?

Inquiring minds need to know...

Cheers

Les

If it's the engine mount you're talking about, yes, mine were way off. After consulting with Vans I pushed and pulled on the mount, by hand, as hard as I could, and then tied it with rope to hold that configuration. That allowed the very undersized pilot holes to be within, but no where near centered, when viewed thru the mount holes. I used the mount as a guide for the drill bit, and got clean, round holes when done. But not centered on the original pilot holes.

I too had issues with alignment. I used a rope and Polly to stretch the mount. I was able to get all holes lined up. I started with the top, which lined up without much effort for me, then the bottom two outside holes which required a lot of stretching. The hard part was inserting the bolts after having to remove the mount again.

Hmmm

This sounds like the problem I had. Unfortunately, when I used clamps and ropes etc there was a significant flex in the firewall due to the weldments. To me it seems like there is a design issue here.

All these problems makes me want to go back and re-check mine. I didn't have any issues.

The W1002 is not the engine mount. He's talking about the part that it bolts to aft of the firewall.

The area being discussed was built for you in your quick build.
