No luck at the hobby shop today. They don't even have Dumas products. They young man behind the counter had never heard of Dumas before!
David, your list of "supply yourself" items on the fittings kit lists various sizes of aluminum tube. How much of each does one need and all of it is round correct?Comment

Brick and morter type hobby-shops (for the most part) are only good for bad advice; stupid counter people; and paints, adhesives, and other chemicals which are safe, but near useless for the task intended.
Yes, round tube and wire. And not much of either. Does this store have a K&S rack?

They do have a pretty good supply of wood, metal, and foam. Including a full rack of K&S tube and barstock. The aircraft countermen are pretty sharp. One of them is also into boats and told me the props are most likely 5-40 thread. That makes sense as a 4-40 screw goes in great, but a little loose until it bottoms out. I'll order a die tomorrow from MSC or Grainger. Tonight I'll get dogbones and couplers on order as well.Comment

Well, that fell on stoney ground!
I don't think many modelers have heard of BA or ME in the USA.
But - I have plenty of them - my younger son runs British Tools and Fasteners IncStop messing about - just get a Sub-driver!Comment

That being the case I have in the past bought from your son's company. Many moons ago I lived in Boston MA, back in the Uk now.Comment

Ditto that. The imperial threading system is a minefield with all the different standards. Applies to other things too, like converting between distance, volume and weight. I have never reasoned why the U.S clings doggedly onto a measurement system that was superceded over 200 years ago.Comment

Base-ten is the Devil's playground. America stands firm and resolute against the advancing powers of evil!
Besides, this metric stuff is just a fad. I refuse to abandon what works for the measuring-system-of-the-moment.
I don't take to changing styles and terms easily. Try this on for size:
When I was a kid, blacks were first 'colored', then 'Negro'. As a young man they wanted to be called, 'ebony', and finally, 'African-American'.
A confusing mine-field erected to keep all non-blacks off balance in the presence of blacks. I don't play that game.
I refuse to employ any term to describe these guys other than black! That's the only racial term for that group I'm comfortable with, as it's land-of-birth neutral and rock-solid descriptive. As descriptive as, oh, I don't know ... white!? Why, for God's sake, in this country, do they require a 'Black Leadership'; a construct which is so pleased to keep changing the social ground-rules. And why do the rest of us buy into these word games?
And I'm comfortable measure things employing the imperial standards.
(where the hell did all that come from?!).

I must be getting old, because I still have to convert centimeters into inches before I have a clue how long something is. Particularly model submarines! Hopefully the USA will hang onto this archaic system for a little longer.
It's funny, I don't have a problem with meters and yards, or kms and miles, its just those little ones, mm' and cm's.
Mind you, the system will never change here, because the people who need to get it done can hardly read, nor have a basic understanding of simple maths - I refer to Congress!Stop messing about - just get a Sub-driver!Comment

Going by things here in the UK, it takes about thirty to forty years or so to effect the change. At school, I was taught both systems, but with a bias towards metric. However, I notice people in their twenties are clueless about imperial measurement, which suggest it's no longer taught in schools at all.Comment

I never had a clue about thread sizes, whether they were imperial, US or Metric, until we acquired British Tools & Fasteners. The inventory came to us from California on several pallets containing boxes of nuts and bolts and other weird stuff. Inside the boxes were plastic bags with felt tip pen markings on them. Unfortunately, the writing had rubbed off many of them, and worse, there was no count on the quantities. So, I had the miserable job of identifying the components, and counting them. It took me almost 2 months to get them organised, and then I had to enter the info into the computers for the invoicing and the web page. It was not fun!
It was a good exercise for me mentally, and eventually, I got to understand why these threads were the way they were, the history was quite interesting.
However, I am still at a complete loss when it comes to identifying which spanner to use on which bolt. I usually go to the toolbox, grab a handful of spanners and systematically work through them until I find a good fit. It would make a real engineer cry to see it!Stop messing about - just get a Sub-driver!Comment

Getting back on topic here, the question was asked -which threads on the Raboesch props?
All 180 series 7 blade propellers have a hole with a set screw to secure them to the shaft.
All other propellers have a screw thread.
1/8 shafts = 1/8 UNC Screw thread. ( taper nr 5 -40)
3/16 shafts = 3/16 UNF screw thread. ( taper nr 10-32)
When I asked them if some of the threads were reversed (ie left or right hand threads)
they said "use a contra nut', and I'm not sure what they meant.Last edited by Kazzer; 10-31-2011, 10:46 AM.Stop messing about - just get a Sub-driver!Comment

My understanding is "Use a nut to lock the prop"Comment
