A-1148 "Tailwheel Spring Upper Support"

Is this the plate at the base of the tailpost?

If yes, can one purchase that piece of 'channel' or can pieces of 4130 be welded to form it? - Mike

Mike,
You are correct with that number on the TAIL SPRING SUPPORT and it does weld on to the tailpost/longeron intersection. I just sold my last one (factory PMA) to Craig Gunder, but there was someone about a year ago that produced a few of the owner supplied parts - do a search and they should pop up on the site here. Well worth the effort to get the new bracket to weld on when doing the repair. N3034N

There is a bracket on ebay. Look under aviation parts. George

George - thanks, but that doesn't look like the one - Mike

Ouch. What were the chances I'd figure out I needed the part just after it got sold?
Any suggestions?
Any reason I shouldn't attempt to build it myself? - Mike

I did a query without luck; anyone familiar with who Arnold might be remembering? - Mike

Make it yourself. You can do it Mike!

I may be headed that way. Have you had to do it? - Mike

Re: A-1148 "Tailwheel Spring Upper Support"

No, Mike, I've never had to make one. I have complete confidence in your ability.

Here's the parts that went into the longeron repair on my airplane.... and the section that we replaced.

Oops! I've been using you as an example! Then who's been driving?

Actually, this time (after initially settling on the most complex solution possible), I thought, "you know, Spruce makes rectangular tubing; wonder if they have something close that I could start with and whittle away from there". They have 7/8 ID, but not thick enuf and they have a greater thickness at a larger ID - the ID doesn't appear to make a difference. So if I bought the stock, the hard part (of making the bracket) would already have been done. I'll spend some time tracking down a lead for the part and if that doesn't pan out or if it's too expensive I'll have an alternative.

Went out to the bird this morning to plug up screw holds in prep for her sandblasting and took a long look at the tailpiece. Have you looked at the weld at the top? That's going to take some heat getting into that cluster and in a cramped place too. Glad I'm not in a hurry. Think I'll start off with the simplier stuff and build confidence. I'll practice each of the welds with conduit before approaching the fuse. Sure wish my AI would have let me splice a piece in vice replacing the 'post. - Mike

Terry - thanks for the pic. Great help. How did you cut out the 3/8" radii?
While studying the blueprint, I noticed what appears to be three 'bumps' on the bottom. At the time I couldn't tell what they were for, but when I went out the the plane, sure enuf, three bumps on the bottom of the plate. Any idea what they were for? - Mike

Mike,

On the L-2 felt was used between the bracket and the tail spring. The three bumps help to retain the felt. There are three bumps on the bottom tail spring bracket also.

Re: A-1148 "Tailwheel Spring Upper Support"

Mike,

Here are a couple of L-2 Documents, the felt pad is item 30 and equates to A-5018 in the drawings.

Re: A-1148 "Tailwheel Spring Upper Support"

The felt and bumps are the same on my 41 BC-12-65 (except the felt is a piece of rubber on mine).

Wouldn't felt hold water against the steel and eventually rust it out? Anybody know what material is "supposed' to be in there?
