To those that use threaded inserts, what grid spacing worked best for you?

Streedrodlover,

I have a 4in x 4in spacing over the entire table, and then a 2in x 2in spacing in the middle fron 24x24inchs of the machine. Works great.

Thanks nlancaster, I was thinking 8x8 at first then mapped it out and it didn't leave much options. I may go to 5x5 and use a closer cluster in the middle.

Are you guys using like a 5/16"-18 ez lock insert? Do you epoxy them when you install them? I've used them on other things I'd just be a little concerned about being able to get the clamps tight enough.

I have not cut mine out yet but I plan on putting them in the bottom birch layer and gluing them in so they won't come out. And I am going to use 1/4-20 ez lock zinc inserts.

In the table on my homebuilt machine, I used 1/4-20 t-nuts sandwiched between two layers of MDF. I routed pockets for the bases of the t-nuts.

I use a 3" spacing along the Y axis, and for the X axis, I start at 3" for the first 24", then use a 4" spacing.

I used 1/4-20 Ez Lock inserts into a main table surface of Baltic Birch. IT was only $60 for a 60x60inch peice of baltic birch from a local supplier. I would not use those Ezlok inserts in MDF, I think it would be too easy to strip them out.

I did drill all the holes in the table for the inserts using the CNC Machine itself :D

I planned to use the CNC to drill wanted to use mdf for for base board simply because I have no local supplier for Baltic birch but I'll probably see about sourcing some for this project. It should be worth it in the long run. Went this far. Haha

100 Pieces Threaded Insert Nut 1 4 20 Int Thread Made in Germany | eBay (http://m.ebay.com/itm/320969720462?nav=SEARCH)

I use inserts like the link above. EBay has tons to choose from.
I drill the holes with the cnc. Then I threadmill the holes and glue the inserts with a drop of superglue between the threads. Works great.
