Hahaaa my brain ALWAYS stutters whenever someone mentions "aluminum", but I've learnt to not bother spend energy on the matter. Thanks for thinking of international accuracy! It's actually not even just metric, but moreso scientific; only in the US and Kernoodle do people say it that way (so not, for instance, in New Zealand or Australia or any other English speaking or "imperial" country), and recently a motion was made to not spell it thusly in scientific papers or engineering circles when accuracy is needed.
Thanks for watching. From the tear apart thread I saw on cloudynights, it looks to be the same bearing size used in the AM5, so maybe close to that? We'll see I guess.
Ah matching tie & handkerchief album by Monty Python that takes me back to my youth, a good friend of mine bought it & found out after a couple of times playing it was one side of the album had two grooves cut into the record as it started playing stuff he hadn't heard before, really freaked him out ha ha!!! As for the build it's coming on great, it doesn't have to be a thing of beauty as long as it functions as it should so really looking forward to the next part of it's construction, I don't suppose you could list the price of the build when it's finished as it would definitely be an interesting comparison.
Yes I had the same album. I had the same confusion. In the first video I stated I wanted to keep the budget around $500. I think I'm coming close to that, hopefully not too much of a cost overrun. I will have a cost total on the next video.
Very nice project, I would like to see the next parts! I am afraid you need one or two additional bearings. The wave-generator is not sufficiently enclosed: it can move in the axial direction and has a tendency to tilt, especially under the load of the timing belt moving an attached telescope.
I think a "normal" 6xxx series will be OK. Mount it in a bracket at the outside of the timing belt pulley. Best is to take the ID a bit smaller than the pulley shaft (8mm instead of 10mm), fixate the shaft in the bearing with an end screw. (You need a lathe for this). Fixate the bearing on the bracket and the shaft is supported and axial enclosed.
@@DhansvwWell this sounds a bit above my pay scale :) and I don't have access to a lathe at the moment. But thanks for your input and I'll definitely look into it.
I experienced this on my DIY mount. The 60 tooth pulley is so heavy, that at 40° tilt, it starts pushing the shaft down into the gear until it is yanking on the belt.
@@whyf16uy Thanks for the info. i'm trying a test with a 3d printer mount including the harmonic drives. If it does not work well i replace the 3d printed harmonic drive with metal ones.
HaHa! "Aluminium in metric" 😆😂🤣 It's great to hear an American saying it properly... In English. I always wondered why you don't also say "magnesum" or "iridum", just singling out aluminium for the missing letter. I know it's no fault of any current Americans. Aluminum is 'proper' over there. Probably that Webster's fault many years back?

@zbnmth you can have my aluminum when you pry it from my cold dead fingers
@@whyf16uy tempting offer ;P
Nice project, I've been watching them back to back, but now it's bedtime. Clear skies from the Netherlands!
@@zbnmth thanks for watching. Hope you get something valuable from it.
I'm really enjoying your project thanks for taking the time to make these videos, what weight do you expect this mount will be able to handle

Really great content!, love the little jokes jajajaja
@salomonwachholz8254 hey someone gets me! Haha

What type of bearing? Where would they go?

Beauty is in the eye of the beholder... Even if it doesn't look pretty, it's still a beautiful thing you're creating.
😁 Thanks
Where did you buy your controler

How thick is that aluminum?
.25 inch
That's what I'm working with also. I wonder if my design suffers from having everything in a single 6" cube. I could never get the guiding under 1.
@randomtinkering well that's what the big guys use, but with the alt az adjustment I ended up with I went with 2 smaller cubes

Well someone commented on my imperial measurements so I had to throw that in there
@@whyf16uy Metric is just a fad, it'll pass...
