A stones throw is the length of a cricket pitch . That’s 66ft . A normal throw of a stone is 66 ft or if you bowl a cricket ball it’s 66ft or a chain. I used to play cricket at school and recall some of the rules of then. The cricket pitch was 10 ft wide once but the “poms” [english] requested [forc...

Firstly, I am NO expert on 1948 cessna 170,s . But I do own a 170A series. When I replaced my firewall and for insulation i used a black closed foam with aluminium foil covering on one side and a thin “lead “ foil on the other . I purchased it from Spruce. It’s about 1in in thickness . When I replac...

so sorry George ,but unfortunately in this country all fluids are measured in litres. But height/distance is measured in feet in our aviation world ,but there are exceptions . Now to confuse you even more , on the ground we talk in terms of temperature it’s Celsius BUT when flying it’s measured in F...

All my vacuum gauges are gone . They have been replaced with 2 of G5,s but I left my ASI and Altimeter behind . All engine instruments are now “Electronic International digital . HUGE weight saving . The G5,s have each a standby battery . My biggest problem was aligning the Magatron in the wing . Ge...

I would be doing a load analysis of the electrical system and including dead battery situation. In Australia we have to have a listing of all electrical loads in our log book. I had a STC for a 100amp alternator when I put the Lycoming in originally. While it worked a treat it was a massive overkill...

We have had nearly 3 weeks of constant rain and yesterday blue sky. A friend and myself decided to go for a couple of hours flying. Nil wind , some clouds at 6,000 ft nothing to worry about. Temperature on ground 95deg F ,humidity was 97%. We were in a Cessna 172 [his]. we had 120 liters in tanks . ...

While there was a heap of thread drift the subject matter i was referring to was about the repair of the undersurface of a 172 C wing, We were using 6061 T6 alloy . But the next size up from standard and dimpled with a press. Our instructions came from Cessna engineering. why Cessna wanted counter s...

Just come from a meeting of a number of aerospace engineers and some i have worked with for many years . We were discussing Cessna repairs and drawings from Cessna . It appears that Cessna paid advice from engineering isn’t consistent with their structural repair manuals . [This is the reason of the...

We had to do a repair on the undersurface skin of a wing of a cessna 172 C . It had a gouge of about 10 to 12 ins in its undersurface and about 1 in deep . This was due to some one trying to jack the aircraft using the tie down ring on the strut. The jack went for a walk. The damage was then bondo f...

while the Franklin engine is a interesting engine and has some great aspects ,but i was under the impression parts are a issue these days . I know of [well did know of] a 220hp engine fitted to a Cessna 170b and it flew like a cat off a hot tin roof. However obtaining parts was a big issue for servi...

The one on ebay does it have the same part number . It might “look” the same BUT ,does it have the same thickness and aluminium type . Many people assume 2024 T3 is used every where But surprising it does not . One would question the condition of the ebay part and it’s aluminium condition under the ...

We had the SIDS program forced upon us and thus a very detailed inspection had to be carried out . This inspection wasn’t flexible at all. The aircraft was stripped totally and I found my whole aircraft had been zinc chromated at one stage of its life . The gear box section was closely inspected as ...

It was only doing the SIDS inspection that I realised my wedges [shims] were fitted upside down on one leg. [LH]. My aircraft was originally a project aircraft that i built /finished up. There was nothing in the logs about a gear box replacement at all. I had a number of qualified people measured an...

There is so much knowledge and experience in the membership of this organisation it will make your project an enjoyable task. The forum library has just about everything that you would wish to know ,but saying that I found it a bit clunky to navigate . Going to the convention also is a great source ...

I think the less “disturbing” of an airframe in rebuilding is the best thing to do especially if you do not have a fuselarge jig. Projects are great when things go right and you know you are right. I have had people say “I followed the structural repair manual to a T “. It’s some times interpretatio...
