Dave -------------- Original message from "Bob Conner" : -------------- This is what my engine mount looks like. Now while I have this all off should I put the tubes on the bottom like Dave said he did on his? The way I remember him saying was to add a couple of tubes to the bottom mounts over to the side. Am I remembering right???????????

When we stripped the fabric off we got a shock. There used to be a lifting handle on the port lower longeron, just in front of the tailplane. Years ago it broke off, it was patched over with fabric and the back end was lifted by picking up the tailwheel spring. When stripped, we found that where it broken off it had taken with two circles out of the wall of the longeron, about 3/4" diameter. It had been like that for 10 years or more!

We had a close call early this summer when two airplanes landed in opposite directions. The prop on the plane rolling out on the ground got the wheel pant of the biplane still in the air. The biplane guy went around.His main gear was dammaged, but functional and he landed safely. Investigating the damage to the biplane we (months!) later found the lower longeron / firewall tubes broken on both sides of the plane.

Every time I failure check a practice weld it breaks about where yours did. I've found Tig welds seem to be more susceptible to this than than gas welds. If I were you I'd replace the entire tube.

Jim C -----------(eom)------------ Another approach is to find a next-size-larger tube, split it lengthwise and use that to patch a break. But do check 43-13. There are some gotchas that can cause problems later. Like squared off ends on the reinforcing tube? That creates a stress rizer at the end of the patch. On my bud's biplane... The vertical tubes at the firewall still had the little circles (of the broken off longeron) so we carefully took those off with a die grinder leaving the bottom of the tube perfectly shaped (and still closed off). The bottom longerons were sliced off a few inches ahead of the main gear cluster leaving a nice stub. A new bottom forward longeron (next larger) tube was slipped over that and nextled neatly to the bottom of the firewall tubes. The diagionals on the sides and bottom were spliced the same way. It's all welded up now and he's patching up the cover. Ought to be back in the air again this year?

Richard and JohnD and Malcolm are doing a breakfast jungle. There's a tiny lunch box at the field. Two minutes of walk up the highway takes you to Sam's Place, a nice ribs restaurant decorated with model airplanes for dinner. And as Dave Stamsta revealed, there are a couple of superb ice cream places in Plainwell. Kalamazoo has the Street Rod Nationals North going on this weekend if you want more than food. But mostly it's a chance to go over Wittman designs and put faces to some of the names you talk to here and can use as a midwest resource for those building questions. Hopefully there will be one or more Tailwinds. Get you motivated. That's about as far as it goes for Tailwind planning. Be looking forward to meeting you whenever you can make it. Bring your rib and Buttercup plans to share. I expect we will be there on Saturday and early Sunday before heading back home. If anyone is planning on staying overnight, you may want a tent as there is not a motel room within three counties due to the street rod show. We can put up a small crowd if you need to have a couch to sleep on and a shower. Eric - (269)382-3709 Joe Maj wrote: What's the schedule? I can drive down for a few hrs visit on Sat.
