That's actually smart advise, thanks. I haven't considered those bits, I am quite unfamiliar with them but I remember seeing them somewhere......
It's just that I don't have the steel bushing but I have the bearing and it will only take whatever forces will be there in 50 holes. I don't...
Hi guys, I am interested if having two holes per tube-to-tube connection is harmful to the possible weakening of the part compared to having a...
I figured that bearings must be the best bushings ever... they are hardened steel and they rotate with the drill bit, having no wear due to the...
I hope that doesn't happen. I'll have to see what metric coupling I could use so that after drilling out the threads I end up with an M5 bore....
Hello, I have a project where I need to do some pretty straight holes in aluminum square tubing and I am designing a "tool" to help me with that....
Here in Europe the market is much more fragmented and spotty than you would think and transport between countries is too expensive so we rather...
I wish that was available in my area but the hardware stores around my area do not carry that kind of perforated square tube. It's a shame.
Glad to see that my idea has chances to work :). I am a lot on the move and going from country to country with the job in Europe and don't have...
Yes indeed that would be sweet and I thought of that even with off-the-shelf (sort of) parts. Ikea has a bin of unused/returned metal...
Thanks for doing that, I wasn't expecting anyone making experiments on my behalf. I am aware of the angle trusses stuff but I find it a bit...
The length of the U-bolt is the real issue here, as I can't find such small U-bolts that have legs longer than 20mm or so and I must span through...
The square tube is 20x20mm so at 2mm thick walls I am left with 18mm of U-span. If I use 4mm threaded rod, that would leave 10mm for the radius....
