Did some more mods the other day.

I moved the Y axis belts to the outside, did the double-X axis mod and mounted my Rigid trim router.

Very nice! (esp. the detail photos on your blog).

Could you post the details of the spacing materials you used? It looks like your 2 Makerslide pieces are tight against each other? Did you bolt them together?

You are correct, I forgot to detail what I used for the spacers.

I actually re-did the spacers this evening because I wasn't happy with it. I had to dig around in my parts boxes to find washers of various thicknesses to make the plates the correct distance apart.

I purchased the spacers from McMaster-Carr.

The long spacers on the top are 25mm long and I had to add some washers to get the V wheels to sit down on both rails at the same time.

The long spacers on the bottom are 51mm long and also have additional washers.

I suppose to do it perfectly correctly I should take it all apart do some measuring to figure out what the exact spacer lengths should be and then make some to suit. Sounds a lot like work, especially since what I have seems to be working now. :)

I imagine I'll do it at some point. I can probably take the measurements without disassembling it.

I did not bolt the two pieces of MakerSlide together. I just held them in place and tightened the bolts on the ends. I don't think they are going to go anywhere. If it turns out I am wrong it will be simple enough to add some bolts.

Thanks.

Someone, (Cat / cvoinescu I think it was) opined that fastening wasn't necessary for shorter lengths, so you should be fine.

I'd really like to see a finite element analysis on what length needs how many bolts at what distance though.

More work on the ShapeOko build. I built a new base for the machine, but I'm not entirely happy how it turned out.

Those riser's are a great idea, I can't count how many times I've had the Y-Carriages smack into a work piece because I misjudged the amount of clearance.

If you do revisit the base, you might consider a torsion box version like this: http://www.shapeoko.com/forum/viewtopic ... =382#p5263
Mine used 1/2" MDF on the top and 3/4" MDF for the support grid, the result is rock solid.

The torsion box is a great idea. I'll have to noodle on that a little bit. Thanks!

A new update in the accuracy front.

I squared up the X and Y axis yesterday, but still have some more work to do.

Building a torsion box table is moving to the top of the list I think.

Full details on my blog.

More updates. I've been doing all kinds of things to and with my ShapeOko this weekend.

Here is a teaser photo of the air deflector/dust shoe mount I made:

I have been using craft foam for my new dust shoe and I am pretty happy with it.
It flexes nicely and seems to be fairly sturdy.
