Trade airbox and Brackett filter for unfiltered airscoop

[Joel Severinghaus]

I'm restoring my '46 BC12-D back to its original configuration, and would like to trade a three year old carb air box and Brackett filter for an original unfiltered airscoop. Don't have the paperwork on the air box handy, but it was new from Aircraft Spruce, I think. Photos below of what I have, and a photo of the unfiltered airscoop I desire. Anybody want to trade?

Why in the world would you even consider operating your engine with out an airfilter? Engines wear out fast enough with good filtering.

You might do a little more checking, but I think the 46's came with airfilters. I do know the pre wars did not have them. Tom

I know, I know. But she left the factory without an air filter, and flew without an air filter for her first 57 years. The guy I bought her from notched the nose bowl to fit the filter, but didn't install a filter fairing. I'm being purist/stubborn, and restoring her back to original. (Keeping the Case mags too, rather than upgrading.)

I fly on concrete or green grass here in Iowa, so I'm not too worried about dust/sand/gravel injestion.

Talked with a Taylorcraft pilot from Nevada at Oshkosh last summer (also flying on Case mags) who has a piece of screen over his unfiltered airscoop -- keeps out the big grasshoppers, he said, but the little bugs just go on through for lubrication.

Which brings to mind an Iowa lawyer joke: How many lawyers does it take to grease a combine? Just one -- but you have to run him through twice.

Well Joel your deluding yourself thinking that flying off concert or grass will not get any dirt into the engine, case in point after mowing my runway (its grass and very nice lush grass) with a Ford 8N with and oil bath air cleaner there is about 3/4" of mud / dirt in the oil cup. The same goes for the "B" Farmall that I use about half the time the oil cup has 3/4" of mud in it. This dirt would be in the engine if not for the air cleaners.
Every lawn mower built has an airfilter the ones with poor filter wear out alot quicker than the models with very good filters.

Joel:
I with you. Let's restore these old birds back to original. Think antique.

My '46 ran almost 60 years, before I got her, with the original airscoop...no filter. I'm restoreing her with the airscoop, like she came from the factory.

Just wish I had the original mags...years ago some yahoo added slicks and cowl bumps!

Same here. Someone did a nice restoration on my airplane but the plastic or FG cowl bumps and Slicks were added. I don't mind the Slicks at all, because I am not an antique purist, but I am in the process of getting rid of the cowl bumps.

FWIW, Fresno Airparts now charges $27.50 EACH!!! for the "Ercoupe cups", and according to Harry Fenton you still have to do some macine work on them. Then the sheet metal repair to the cowling, which has to be flush patched to look right...

Earney Bryant used to have the old style intake tube on his plane and he had a little air filter on it. I doubt it was an STC approved mod but it sure seemed to work well and he could take it off when the ramp check monster came looking around.

Thanks to all who offered unfiltered airscoops to trade. I found one in good condition with factory-original screen over the opening.

Joel:

You have a Factory Original screen? Wow.

How about a photograph and some dimensions for those of us who are not as lucky?

Joel
I agree with Bob. Please, if you can, post a picture of the screen on the intake. I have the unfiltered intake but haven't seen the screen assembly.
Thank you

Re: Trade airbox and Brackett filter for unfiltered airscoop

Bob and Randy,

I was searching threads for unfiltered airboxes and saw that I never answered your question from two years ago about the screen.

Unfortunately, the U.S. Mail lost the airbox with factory original screen that Kevins Mays sent me, so I never did see an original screen either.

However, my restoration mechanic John Frisbie of Aircraft Restoration & Recovering in Kansas ([email protected]) made this grasshopper-catcher (left photo) for my airscoop. Actually, now he's made two -- another recently to replace the original I crushed in my nose-over incident. Two tiny screws through the mesh on the side ears hold it in place.

The other three photos show an unusual screen I saw at Oshkosh last summer on a pre-war Taylorcraft. The pilot's name escapes me, but he and his son were from Nevada. The "filter element" was thin strips of metal.

Re: Trade airbox and Brackett filter for unfiltered airscoop

My '40 BC-65 has only the screen to keep out BIG bugs with about the same screen fastening that Joel described. I put a new copper screen (from Ace Hdw. Aircraft) on at each annual. Dad replace the original engine in the mid-50's as he had a spare with a new MOH. I agree it doesn't sound too good to run unfiltered but that is what a lot of us do.
