Please visit my web site to see some of the slab rollers other potters have built using my plans. It would help greatly if you emailed your slab roller pictures so I can post on my site. This gives other potters confidence to try to make their own slab roller. Also send any changes in design so we can share them with others. This design works great for small production needs and also for some school pottery labs. Feel free to contact me if you have any other ideas to improve the roller. Dale
