Carpet Mill Design plans - Picture Diagrams included

I did not finish. If you make the front and back holes and then add the holes along the mill running surface it gets easier to accomplish but the holes along the rail are so close together it weakens the platform. If you put multiple holes along the legs of the mill getting the measurement correct is difficult. I made one once and it took a ton of time.
I even made one with one angle and put threaded rod in the front legs to adjust the angles. I ended up building them with one set angle and I use a 4X4 as a block to raise the front legs for an increased angle and in the back to level it off. I get three settings with one set of holes. Anyway, best of luck. Looks good so far. I wish I had pictures of the ones I built some 20 years ago and then compare them to the ones I make now. I am down in the less than $150 for materials area. I can build them and sell them for $300 or even less if things are on sale, usually around $275 to $285.
You should continue on with your project as you will learn more and have a more effective mill when you use the trial and error method. Again, best of luck. US1

These two mill have about $250 in materials together. They both serve good purpose. The 1st shows a dog going all out on it. She was 9 or 10 years old in that video so I did not let it go long. It was setting on a piece of wire that led to the slight wobble in the video. The second video is a bitch winding down after some hard sprint work. She is beat in the video. This is a mill my son made as a 15 year old. He made the frame on his own and I did a little 'over-seeing' on the running surface/roller measurements. Worked like a dream. These things have to be effective, and a lot of times simple and easy can be the most effective. US1

 

Best of luck.Not sure where your axles will be on this frame but for future reference if you lay the two side rails on top of each other and drill the hole thru both rails at the same time it will be much easier to square the axles with one another. Post pics as you go. It is not as hard to make a solid mill as most would think. S
