I used a 20 thou (0.02") spacer to allow easy access of the tool arms.
Great - I'll leave it at 31 thou (1/32").

I did not see any other issues with the model. As built things are a little too tight. If I built another one I would open up the tilt lock slot. That slot doesn't need to be tight. I haven't completed that part of my build yet because it will take a lot of filing. I would also open the base plate rectangles. I ground mine a bunch and the still didn't fit. The water jet has a slight taper of a degree or 2 on the best quality cut. It probably wouldn't hurt to open the slots up a few thousandths.
I'll upload the regular version in solidworks and my modified version after Christmas.
Also it might not be a bad idea to go 1.6" on the tool slots.
I've updated the Part 207 - moved the mounting hole to correct location and opened up the slot. The mounting holes are 1.90625 CTC - this allows 1/32" clearance. I opened up the slot to 30 thou - was 26.

I took a look at the base plate and slots there are already .38 wide - 5 thou clearance and 1.0" long - zero clearance. Is it the length of the tab and slot that is causing the problem ( I would expect that this is the issue). If you can confirm this, I will open up the length by 5 thou. That will be an easy change.

After I make that change, I will send the files back to Dan.

I have modified parts 207 and 208. I corrected the hole placement and opened up the slot on 207 to allow easier motion. I have also updated the base - opening up the slots 0.0025" in each direction to allow a better fit to the supports. I have sent the files to Dan as SR2. If there are any other issues found,please let me know.

Hi Chaps! I've been looking through the forum to find the most up-to-date version of the drawings and this version appears to be it (as of Dec 28 2017). Are you able to say when this will be available for download, please?

I'm based in the UK so I will need to convert all the measurements to metric. Presuming I keep all the hole and cutout centres in the same place when converting, are there any other things I need to keep in mind when converting the drawings? I'm not that familiar with CAD packages so this will be a steep learning curve.

Cheers, Andrew

Converting to metric in a CAD program is usually very simple and just involves scaling the drawing to be 25.4 times bigger (converting from inches to mm). The real issue with converting to metric will be the available materials. This design is based on 3/8" and 1/4" parts with 1.5" tool posts. Changing to metric material will require changes to many of the pieces to move spacings to align properly in the metric world.
