thread measurements
Friends, can you please send me the link to measure cox engine threads, such as venturis thread, glow plug thread, etc. etc.
I can't find the thread table, thanks in advance!

Re: thread measurements
don't know where to find the sheet with the different threads But I believe that for the tee dee .049 tink the ventury is 1\4 32 same thing as a glow plug... But I believe Having the complete list accessible would be practical

Re: thread measurements
Thanks guys!
Yes that is the list I needed, but I think I saw one that was complete.
Brad had posted a link once, but I can't find it, since he needed the venturi thread size of .020 and .010
I wonder if there is an equal and complete list?

Re: thread measurements
Don't believe that there exists an entire list but we should have (almost) all the specs on file, in case someone needs a measurement.

ohhh friends here I found the thread in question and the data of the .020 venturi thread.
On that occasion Matt responded! and solve the problem.
(The published table does not have that information)
Here is the link:
https://www.coxengineforum.com/t10561-venturi-thread-tee-dee-020?highlight=venturi+thread+measurement
Mr. Bernie, then I would need to know the thread of:
Cox.010 Venturi?
Glow plug .010 thread?
.010 cylinder thread?
.010 crankshaft thread?
Thank you so much!!

Re: thread measurements
Cox.010 Venturi?
1/8 - 40
Glow head .010 thread?
3281-56
.010 cylinder thread?
same as glow head
.010 crankshaft thread?
Crankshafts don't have threads

Perhaps he's looking for the prop screw or collet?

The prop-screw for Cox TD .010 is a 2-56 X 5/8" according to the MH Aerotools (Martin Hepperle) webpage.

Hi Bernie, Would your 1/8 - 40 answer for the venturi thread be the same thread as the 5-40 thread used on the .049/.051 crankshaft threads? It would be easy enough to check with a .049/.051 prop-screw.
Regarding your 3281-56 answer for the cylinder/glowhead threads.. Are you meaning .3281" (decimal; taken to the ten-thousandths place) diameter? This would be 21/64" if converted to fractional.
I never owned a TD .010.. but is there a backplate/thread?

The 5-40 seems to screw into the carb body correctly.
3281: Not the foggiest idea, sorry. The measurements were taken from the drawing.
These are the crankcase screws: https://coxengines.ca/cox-010/cox--010-020-backplate-fuel-tank-1-4-screw-4.html
Re: thread measurements
Thanks Mr. Bernie for the information!
Thank you all for collaborating.
Yes, as Jacob says, propeller screw measurement = crankshaft thread measurement (only front thread that the crankshaft has)
....I'll tell you a secret hehe...a friend sent me a Cox Tee Dee .010, he thinks I'm going to take very good care of it, he bought that engine a few years ago, he used it and now he wants it I keep it, so I am waiting for it.
In the meantime and to save time, I wanted to know the thread measurements in case there is something to reset.
In Argentina it is difficult to find equivalent tools, sometimes some appear, other times you have to adapt.
I'll show you the engine as soon as it arrives.
So: with this data, is there any possibility of adding it to the digital table that appears on the web?
Thanks guys, I'm keeping an eye on this thread, all information is very important and safe to avoid damaging priceless pieces!

Re: thread measurements
So to complete, the thread measurement of the nut that threads into the crankcase and tightens the crankcase body would be missing.
Extent?? Thank you!!
