Re: 1955 Cessna 170B rebuild

Sounds like there is a hot wire on one side of the master relay which goes to the starter switch which is cable actuated.

You're shunt will measure amperage in line with whatever circuit it's placed in. If you put it in line with starter cable which only goes to ground while the starter is engaged then you'll be measuring the amps being drawn by the starter. If you put it in line with the wire going from the master relay to the buss then you'll be measuring current drawn out of the battery by system loads.

Man, if you're going this deep, can you convert to a more modern starter motor/solenoid/switch? I never liked the pull starter.

That is a good point as well. I hate options :)

There is a new starter that saves some weight made by B & C products that allows you to put in a key and a push button switch. Small price tag of around $620 i believe it was. Maybe some day, right now just want to get it up and going and put that money towards fuel.

Re: 1955 Cessna 170B rebuild

My old 170 had the C145 èngine with the pull starter & it worked just fine.
You did have to make sure it was adjusted properly with regards to the linkage fully engaging the pinon gear before the starter motor was energized, but that wasnt hard to do- just follow directions.

Re: 1955 Cessna 170B rebuild

81D had an O-300D with a starter solenoid on the key and I always thought better of it.

When I got 95D, she still had the C-145 pull start and I REALLY liked it after the first start. It's just a cooler way to start a motor and made me feel more connected to the plane. Odd, weird, crazy but I like the pull start better.

Re: 1955 Cessna 170B rebuild

Kinda starting to look like an airplane, too. After shadowing your trek from ground pounding to private pilotdom, I'm looking forward to your finished product (probably not nearly as much as you are, though, right?).

Re: 1955 Cessna 170B rebuild

Thanks guys, its been a hell of a learning experience and still so many ways to do things differently. Paint is in the near future without a doubt. Just want it to be safe, clean bird that I can build time in and continue to learn in. Just completed my single engine commercial checkride two weeks ago. Ready to build that time!

Looks great! I know how much work that is!

What did you use to seal the windshield? After a rain storm dumped on my 180 while it was parked outside a couple weeks ago I found out it leaks like a sieve!

Re: 1955 Cessna 170B rebuild

That looks great. It appears that you didn't paint the floor (maybe an illusion?). If so, what was your reasoning there?

I used the felt and strip caulk. Then used an aircraft RTV sealant for the final outside seal.

I did not paint the whole interior like most have done previously. The floor will be covered with carpet or Aerodot flooring. Hoping to spring for the Aerodot however I already have carpet. It just simply comes down to money and time.

Re: 1955 Cessna 170B rebuild

The carpet acts like a filter catching all the sand and grit. You can then pull the carpet and clean it, and hopefully not have most of the junk not in the recesses of the plane.
