Hello Phlat Bro's I wanted to make a simple mod to my MK-II that would allow me to adjust pressure levels on all three rollers, individually, without making it difficult to load materials or remove the top for bit changes. So far I have only modified the feed pressure roller, but should this effect the contact of my material with the cutting surface, I will modify the rollers over the cutting area. With only the feed roller modified, the top can be opened to load material without disconnection the turnbuckle. In any case, here's what I came up with. 1. Trace the roller guide cutouts onto both of the outside side pieces of the top assembly. 2. Cutout and sand the additional guide slots. 3. Replace the original roller rod with one long enough to protrude approximately 1-1/2 inches from each side of the top assembly. 4. Reinstall the roller using the original instructions, ensuring that the rod extends equally on both sides of the top assembly. 5. Slide one end of the spring loop over the extended portion of the rod, followed by a nylon spacer. The spacer prevents the spring from sliding off the rod and protects the user from the end of the rod. 6. Trim rod length as desired. 7. Attach bottom loop of spring to the closed loop on the turnbuckle. 8. Locate and pre-drill holes to install a stationery hook that will capture the hooked end of the turnbuckle. With the turnbuckle fully closed, the spring should be taught when no material is in the machine, but it should not apply pressure to the spring. 9. Install stationary hook and capture the turnbuckle. All of the part I used were purchased at Lowes Home Improvement: Spring - Extension 7/16"x3-1/2"x.047" item #08236-80101 (2 per pack) Turnbuckle - 1/4"x7-1/2" Item #038613-124998 Nylon Spacer - 5/8x1/4x3/8 Item #08236-70836-3 (2 per pack) with the specialty fasteners Stationery Hook - found these with the picture hanging items Have fun, Dell aka RCRerun Attached files
This is so funny because I was just thinking about this same method the other day for something I'm working on with my MK1. Good job man!
That is a great mod Dell! I love the fact that you kept true to the Lowes hardware parts too. Super job Dell thank you for sharing this with us Mark and Trish
Dell, neat idea. I have noticed recently that I cannot cut either pink or blue FFF. The surface is uneven and my guess is when one of those "dips" or depressions hit the feed roller it loses its grip and the material doe not move and that, of course, messes up the cut. Do you think your spring system will help to solve this problem? Chuck ...somewhere in Indiana...
