Hi Group

I'm going to take the plunge and make a Joe2006.

Angle Iron Bearing Support Question:
The PDF file drawings do not show :

1) All The necessary dimensions to place the hole for the bolt to hold the bearing (For Example - on th Z Axis Bearing Support - it shows tha the holes are placed in 0.375 and 1.125 inches in from the end (say X Dimension) but does not give a Y-dimension. Looks to be around 1/2 or 5/8" on the 1.25 " side of the angle iron.

2) Don't show the dimensions of the hole (believe it to be 0.25")

Any help is appreciated.

Joe

Just use the dimensions from the J-gro..
it's 0.433 inch

I think I read somewhere the PDF drawing was at a 1 to 1 scale. You could use this drawing as a drilling template

I too am having a little trouble with the dimensions of the slide bearings.
I can't seem to find a pdf with the drawings of them anywhere.
Can someone point me in the right direction?

Thanks,
John aka clueless newb

Thank you!!!!:rainfro:

The bearing bolt holes are for a 5/16" bolt, just drill 5/16. And 1/4" for the rail mounting holes. The 0.433" dimension is the most critical - it's half the diameter of the bearings. If you get it right, the surface of the bearing will perfectly match the opposite side of the angle. But, it's probably more critical that they be identical than exactly 0.433. Ten mils off either way probably won't matter as long as they are all off the same amount - I finally used a drilling jig to control that dimension.

Does anyone have the Bearing Support drawings at the actual size. The PDF's are not true to size and I can not get them to print at the true size to be able to use them as templates.

Thanks

Glenn,

If you do a search for "print dwg" or "print dxf" you'll find software that will print DWG files. Then you should be able to print Joe's orginal DWG files to scale. AutoDesk has DWG Trueview that allows you to view and I believe print to scale at this link:

I have AutoCad, I guess I need to look back throught he files, I did not see the drawings of the bearing supports in those files.

Here's a link to the most current files I think,

http://www.lumenlab.com/~joe2000chevy/CNC_Model_2006_R-1/

It's about the 4th link down just below the avi movie.

Just looked through the DWG files again and I do not see the XYZ Bearing Support files. Just to be sure I am talking about the aluminum angle parts that hold the bearings. I may be calling them the wrong thing.

Thanks
Glenn

Since all the holes are same distance from left 0.375 and right side1.125. and the top of the angle 2". I juse made a template from 1/4"x1" steel.I made it same size as Z axis just align it on top and then drill ( I made the template with 5/32 holes) on other axis, just align left side clamp drill unclamp slide over to other edge (rightside) clamp and drill. flip over angle repeat...
I was having problem with not getting holes exactly the same ( cheap drill press)

Glenn,

Sorry about that, I misunderstood what you were asking for. :o

Here are the dwg files I did to use as a template:

34592

34593

34594

I print them out using the 1:1 setting "centered" then used a straight edge and a razor knife to cut them out.
Double check the print out to verify that it's to scale prior to drilling :)

Bob

Which version of Autocad did you use. I have 2002 and it says "Drawing was created with an incompatible version"

Thanks

I use AutoCAD LT 2005. I've saved them to the 2000 file type this should work with all versions from 2000 up.

Hope this works out! :)

Those work great!

Thanks to both you and calgrdnr

As I have a 2500# CNC Milling Machine at home, and would like it to start earning it's keep - I thought some people here might want to just buy the bearing mounts (the angle iron) pre-drilled accurately and ready to go.

Would anyone here be interested in buying these?
If so - what would you be willing to pay?

Thanks

I'd be willing to buy the angles precut and drilled. Not sure what the value is... I'm basically lazy so this is a way to not have to drag out the drill vise and toys and setup for this. If you come up with a price tag let me know. I'm guessing just cut and drilled they would be worth something on the order of $5 plus material cost.
