Fixed Gantry Router

**Gary** · 11-05-2009

Allready tried that Lee, while the hole is the right size the fixing holes will not work.
I had some made that were the same size as the SMA20, and this worked.
SMA16 was too small.

Even easier solusion would be to make a bush that has an id the same as the od of the 16mm ball nut and od the same as the ID of the SMA20.
Then there is enough ali on the SMA20 to drill and tap for the ball nut flange.

I had some made that were the same as the SMA20 and size wise it worked very well, but making it was too expensive and now i get them from China allready made.

Does that mean your gong to be selling them Gary? That would be good.

Keith: Contrary to my usual practice, I had my phone with me all day yesterday and it was charged, although being Three it might not of had a signal. Bit of a shame really because the space underneath for the mount probably could have been left untouched, or at least only half a mill taken off, cause it sits slightly lower than the table. I thought I mentioned that? Anyway never mind. Its still looking mighty fine.

I did have a little concern about the channels not being wide enough but looking at my carriages, I'm sure they are. Might even have a few mm to play with.

I might just go for a custom mount seeing as everyone has already pointed out how inappropriate the 16mm housing is... I was expecting it too meet up with the table perfectly according to my calculations, but there is about 1mm, maybe less between the housing and the table at the moment. I was Also going to use a clamp rather than screws to hold it in... temporary measure until I could make my own. But it just seems more eloquent to get a custom one made.

Yesterday those plugs arrived from Rohnmac. I was soldering them yesterday, and I now know I f'in hate soldering. Will post pics later on today. Catching up on Lost at the moment :)

Thats a really good point actually! I'll just drill the underneath of the mount then tap it and then screw in a bolt and then that should be enough to hold it right? Sweet.
