Fitting HD 16 instead of MGD 16

[Noplace]

Hey guys, need your help a little. unfortunately something I didn't account for is the small difference in diameter between HD 16 and MGD 16 which is forcing me to use MGD on my Z and Y (gantry) axis and was hoping I would avoid it atleast for the Z.
would you think its okay to just increase the diameter a bit of one of my HD 16 brackets until it fits or should I adjust for the MGD? I was thinking of filing it until it would fit.

thanks!

Give us a clue whats HD16 and MGD 16.?

it must be that http://www.zappautomation.co.uk/mech...t-bracket.html, the other one may be is the open variant.

I suspect you dont have the precise means to open diameters so go for filing it with the digital caliper at the other hand, constantly checking

My apologies for not explaining, as Silyavski mentioned that is the MGD16 and the other one is this http://www.automation4less.com/store....asp?prod=HD16 and if you notice there is a .4mm difference in diameter causing the issue since the ballscrew I got for my Z and Y are from taiwan and support MGD size only, I find it kind of big for Z but I think I will do the design adjustment anyway.

Since the diameter of the hole is not too critical why not just run a 28.5 or 29mm drill through it? It doesnt need to be a tight fit.

Actually, it can be critical depending on how you arrange the ballscrews and mounts. The ID of the screw mount should have a pretty tight tolerance to match the ground outer diameter of the ballnut.
