I used a circle saw for mine. When it was about 1/8" from going through, I flipped it and used the drilkled hole as a guide. All cut perfectly.

Ok guys and girls after a year of research on here I'm ready to build the Jgro design it's small and simple and can fit on my work shop with no problem. I started cutting some parts today I got the cutting table done and now I'm working on the adjustment block large. Has any of yall had any problem cutting the hole on the adjustment block all most all the way through and the MDF comes appart on the bottom I've went through 7 and only got 3 so far. I'll have swap to delrin soon.

Hi - I used a Forstner bit for all my holes in MDF. I did not get any tearout but you do want to clear the bit before going all the way through. Th MDF I used (Lowes) has a paper surface that seems harder to penetrate.
Hope every one had an happy safe easter. Well I got a little work done I'm just about finish my large and small adjusetment block I need to get an
13/64" drill bit bummer. I done what Mr. Wild said drill half way through and flip it over I didn't have any that broke off Thanks for the tip Mr.Wild.
I will be glad to get any suggestion. Now I also got the dial rods but was thinking of using this steel rod I may pass on it to much cutten. One of the pics has where it wood broke off. Hope fully will get more work done tomarrow and doesn't rain. I first pic is the cutting bed I'll wait and rout the
t channels near the end Oh yah I'm ording my delrin and hdpe tomarrow.

Well just order my delrin and aluminum angle from mcmaster-car.com she told they will be here tomarrow luckly they have a divison in Georgia. Well back down to the dungin to do some work.

Just wonering is there a mistake on the z axis liner bearing asembly it reads 1/4-20 x 1 1/2 when I stick the 1/4-20 x 1 1/2 through the angle and wood it does't go all the way through has any of yall had this problem or I miss something ?
Oh yah What Kind of paint do you use on MDF ?
I went back down to the dungon and looked at the z axis liner bearing I didn't cut down
far enough where the 1/4" x 1 1/2" gose I dremel tooled it down just a little and it fits perfit. Now I got the z and y liner bearing asembly done I'll do the x liner bearing tomarrow and be done with that and cut the big pices.
