Don't get me wrong, it was very tight, but we were able to get it not to rub.
Good luck! ----------------------------------------- From: "Corbin via Groups.Io" To: main@q-list.groups.io Cc: Sent: Thursday March 26 2020 12:29:20PM Subject: Re: [Q-List] Brake (Anvil) Rubbing Tire Awesome....I will go back and look at some old photos that I took to make sure I place them just like they were.

Some of you saw my photos of the dried brake fluid on my brake caliper and now I have another brake related issue I need your experience to help with. First, I was able to get the caliper all cleaned up and everything looks good so I am going to keep an eye out for small leaks.
Now my problem is that the anvil (inside part of the brake caliper) is rubbing up against the tire. No matter how I try and line it up it still rubs the tire just enough to stop it from spinning freely. I even thought maybe I have too much air in the tire causing it to bulge out too far. I will double check that in coming days just in case. I thought I might could get a grinder and grind down the anvil a 1/4 inch or so.....
Any other thoughts? I am certain the anvil is correctly installed onto the caliper and the bolts have no issues lining up and going in.

That would certainly be an easy fix. These were the size on before and on the right side without issue. Nonetheless, I could look into the width difference between the two and go from there. Corbin

Some of you saw my photos of the dried brake fluid on my brake caliper and now I have another brake related issue I need your experience to help with. First, I was able to get the caliper all cleaned up and everything looks good so I am going to keep an eye out for small leaks.
Now my problem is that the anvil (inside part of the brake caliper) is rubbing up against the tire. No matter how I try and line it up it still rubs the tire just enough to stop it from spinning freely. I even thought maybe I have too much air in the tire causing it to bulge out too far. I will double check that in coming days just in case. I thought I might could get a grinder and grind down the anvil a 1/4 inch or so.....
Any other thoughts? I am certain the anvil is correctly installed onto the caliper and the bolts have no issues lining up and going in.

Re: Sparrow strainer stall

Jay Scheevel
Thanks for the standard practice guidance, David. Always appreciated. Cheers, Jay

Your modified LS1 elevator would go a long way toward reducing the workload required of the sparrow strainers, but you’d still need something like sparrow strainers to push the TE down for normal ops. The Roncz airfoil’s elevator is intentionally designed with a slight “reflex” on the trailing edge just so that it won’t need sparrow strainers or trim tabs. I suppose that with a little more work you could achieve the same with your modified LS1 elevator. (BTW, what software is that?)
