Problems getting spindle out

[John Heli]

I have problem with the head of a 3dx500: I cannot open the screws of the spindle. Meanwhile the screws have are round. Can I drill them out? And how do I do this? Or are there other ways? I don't want to mess up the aluminium blade holders.

Is it hex head screws at the beginning, like on the Lepton? Did you try to heat with a soldering iron to destroy the thread lock? Maybe the bearings won't like it but it's not so bad.

Thanks for the hint! I will try it tomorrow.

No chance, Nicolas, I guess I got to drill it out.

if the soldering iron didnt work try a small torch...i have had to do this before...you will need to replace the bearings but it should still be cheaper than replacing the blade grips. Your soldering iron may not have been hot enough to "melt" the loctite...you may even be able to save the bearings if you can heat it carefully enough...

My soldering iron goes up to 450°C, but the screws did not move. I think it is simpler to drill out one screw. Then I have to replace the spindle shaft, but that is cheaper than the bearings.

Damn thing, it is just because they assembled it without grease. Now it does not move and I have vibrations like hell. I just need to open it to put some grease in. :arggg:

yeah thats a good point...just be careful not to hit the grips...good luck and hope things go well...
