Homemade Bandsaw Bearing Guides Tuesday, 23 August 2011 14:15 I wanted to upgrade my bandsaw with some bearing guides. Now my bandsaw is an old Craftsman model and I really wasn't looking to put a whole lot into it, heck I only paid $50 for it in the first place! So looking around I see that Carter makes some for like $170 - what!?! for some bearings? psshhhhh I'll make my own for like $20 :) Read the Full Story

Homemade 4th Axis

I've been working on a homemade 4th axis for my CNC machine - here's the pictures and a few videos! I'll be making some parts with it soon! :)

This first design I decided to go with MDF because it's easier to cut on the CNC machine and I wasn't sure how it was all going to work, turns out the "block" of MDF is pretty solid and it may just work out in the long run - time will tell :)

The first group of pictures and the first video is of the CNC machine cutting out the MDF - I basically made 4 layers and bolted them together into a block... Ignore the brass bushings and threaded rod - that idea was scraped when I worked out how to turn aluminum on the Shopsmith ;) After that I decided to make my own spindle shaft that would fit the bearings perfectly and would also allow me to use all my Shopsmith lathe fixtures (including the new 3 jaw chuck!)

I tapped the end of the custom spindle shaft so I could bolt on the belt gear that I'd salvaged from an old printer (yes I have tons of old printer parts from salvaging the motors for the first CNC machine)

Here's the pictures and a few videos - any questions don't hesitate This email address is being protected from spambots. You need JavaScript enabled to view it. !
