so were can someone get good tap and dies.
I picked up a 14mm and try to tap for a 90 degree adapter and it just was bad. Like the tap was bad.



What material were you tapping? What type of cutting fluid? (Very Important) I get all my metric supplies, nuts, washers, screws, hexagonal stock, taps and dies at http://www.metricsunlimited.com/products.html. They are right across the street from here.

A general guide for metric tapping is to subtract the pitch from the major diameter to determine the tap drill size. IE: A 14mm X 1.0 Metric thread would use a 13mm tap drill.



Some taps near 100 years old, original miniature wood boxes. Still work fine.

There are some pretty crappy taps and dies out there made from "chinesium". Some of them are dull right out of the package and won't even cut threads in aluminum.

[QUOTE=Rudolph Hart;12532625]Thank you jim i had the speakers up loud for that.I assume it's in holland looking at all the pushbikes in the pit area.Nice landing, that guy can fly.

Dave i was aware of the oval exhaust pipe thickness by looking at mine fitted to the fa200r3 but wondered if the ring was the same wall thickness, the three header pipes are very soft material.Like you on the first run i had a lower right cylinder pushrod drop out to the side but it never happened again.I'm assuming the metal began mating together better during the run in and the oil film (with a smidge of castor) kept it in place.




Re, the pushrod that was disengaged, I need a new one and all the ones I have are too short.

I am amazed that it ran like that, it couldn't have for long.

If the pushrod is straight and the tips are undamaged I don't see any problem with running it.

That pushrod is beaten perfectly flat on the end and slides right off of the adjuster screw. This was an occasion when the engine code did not work but clicking on the 120-R-3 then Parts and Accessories did work, they are on the way or soon will be. I should have placed a good one beside it for comparison.

I can see the flatness, before you posted the flatness, I would have said, why myself.

And you can see where it was hitting the rocker arm and almost getting past it. I'll have to carefully check the adjusting screw for damage. I have plenty of them.

Gary i bow to your electrical knowledge, mine is confined to receiving large shocks off very exposed early british bike plugs.Sixty years ago was the last time i saw a lodge plug, watched my grandfather pull it out of a roller lawn mower, the ceramic part was pink instead of the normal white, do they still make them. Very nice prop lock nut, have you made any scale type one's for early aircraft?
Pete, look again, that guy is just a 10y.o. kid LOL, good for him !! Pete, I tell you, that is just how I am going to fly my 115 , I have about $150 parts and tools coming, it shouldn't take too long now

I tell you those kids got it good, like my son, he can touch down so lightly

Hmmmmm

Looks like the high and mighty are hard at work.
Getting to be a lot like Facebook

Anyhow,

The old Rascal 110 got a good workout today. Two hours total flight time.

Lucky you. Weather is crap again. Only got one day of flying in this year, and that was in Iowa.

I donít know how much flight time added up on my Rascel but went through a gallon and a half of gas.
Also flew the wheels off. Good thing I was at Sig they had more wheels. So I could keep flying.

"flew the wheels off", that's some flying there, but I itching to know, how did you land with no wheels ?

acdii, did you hear/read my story of my son landing a plane that stalled right at the top of a loop ?,
well the plane was a cheap SPAD with a Tower's 45 engine, also, it was a friends plane. flew very well. so it stalled at the very top of the loop, so it was up-side-down and the loop was not that high., so as the plane was coming straight down I was thinking that I was going to have to pay out some cash for this smashed plane. but my son (16 at the time) pulled back on the stick, and at the second the plane leveled the wheels touched the ground without one bounce, it was a very smooth landing ! and the plane rolled to a stop, boy I went nuts jumping and yelling "that's my boy, that's my boy" ,

it was a landing like yours> a landing 1 in a million

I make a point to have as few witnesses as possible when landing.

This is what you call flyable weather friends...

I echo mikes praise, to be a top tradesman you need to love your tools.

Bruce, move to western australia where the weather is mostly flyable year round...it's the land of no snowplows (but plenty of other stuff that would like to kill you)

Dave i missed that first time look, that pushrod has been flattened alright, guess i got lucky with the fa200r3.

Lonnie it's horses for courses with chinesium or russianese and many others including your own country, if you do your homework then you get what you pay for. Did you like the pics of the old lodge plugs. Wonder if someone here will spray their own saito fg plugs in flouro orange??

ps mike you chicken...you should be proud to show off your landings and do them with consummate ease buddy, it's them wait a while bushes that usually snag me.

I'll inspect the adjusting screw/pushrod socket in a while, after the morning coffee soaks in.I found a forgotten engine yesterday, a Saito 56 GK, the back bearing is notchy feeling. New Boca's on the way. No fancy ones this time.

The wheel fell off and the left one was about to go.

When landing without wheels they do fancy forward flips with disastrous recovery's.

Nice find Dave, I love my fa56 but the previous owner wallowed out the mounting holes. I've been looking for a good case for over a year but no luck.

Re bearings: That one set of high performance C3 clearanced Bocas you recently bought, has the front seal started leaking yet? Every C3 clearanced front bearing I've tried from RCb and Boca have leaked after an hour of run time. Makes quite a mess all over the plane. Nothing but boca standard clearanced bearings for 4 strokes from now on, the last three sets have not leaked.

Default Model Engine mounting hole repair.

I have a couple of engines where the previous owners have wallowed out the case mounting holes. What's the best way to fix them?

I've considered pressing in brass rod and redrilling the hole locations but some of the holes have been filed out quite large. One hole as much as .187" long. I fear the required bushing dia would land it too close to the outer edge of the lug and perhaps crack the lug when pressed in.

What if I made a piece of theaded aluminum rod and threaded it into the lug with JBweld? No chance of cracking the lug that way.

Oh heck, what am I thinking? I should just send it to Gary.
