Jim-Thanks for the reply-Yes it is an oldie..When I try to turn the bolt both bolts turn...I wasn't sure if using brut strength would mess anything up.  There is a sleeve and a bushing with a set screw-I guess the bushing is setting the sleeve-but again I'm a little shy to start disassembling things that do not need to be undone.  I was going to try some nylon wheels on the machine.  I ended up having to build a table from slot aluminum b/c I couldn't get the wooden table around the corner to get to my basement. I have put teflon rail on with Stainless steel wheels on the lower carriage..I'l. see how that works-if not I'll put on a SS rail.  I'm also toying with making bliss like wheels using an aluminum gusset and SS bearings-but that's later down the road. Edge riders look nice but a little pricey for now. I do have the vertical wheel set up.-I appreciate your help-!!!-Gail

If you build your own wheels, make sure you use 2 sets of bearings per wheel (inside and outside) or wide roller bearings.  That will make the wheels more stable, and provide much better support for the machine.  Bliss is simply a linear bearing system.  You can buy the basic parts on line pretty easily, and then you'd only have to fit them to the carriage.

In my opinion, bliss is un-necessary for vertical wheel machines.  It helps with the horizontal wheel configuration because keeping the wheels adjusted is problematic.  I think APQS made one mistake after another in their design, until it was finally partially corrected with the Bliss linear bearing set up.  Keeping vertical wheels would have eliminated the problems they encountered with their horizontal wheel system.  No one else uses horizontal wheels do they?

Good luck with your project.  Jim

I hope not! ....I agree with the horizontal being problematic...logically I don't perceive it as ideal due to the forces involved...Bliss/Breeze...nice linear type set ups...a later project for me!

Again-Thanks for your input-mail
