Hi, all. I am reassembling my old HP 6” combo unit after much yanking and cleaning, and have had the 1.25” spacer portion that was between the 2 wheels turned down to the same 1” as the rest of the arbor. The plan is to mount 1 or 2 more diamond wheels for a total of 3 or 4 to use before getting to the expando drum at the end.
The question is—how close can the wheels be to each other before grit cross contamination is an issue, if it would be at all. I can get three 1.5” wheels on with 3/4” between or four 1” wheels or some combination.
Thanks in advance for your input, Biggs (Larry)

How much work is it to mount wheels? I change water going from grinding (80,220, 280 soft) to sanding (soft 600,1200) to pre-polishing (soft 1200, 3,000). A Genie tray is in groups of 3. If I was ever in a situation where I had limited space, I could get by with a two wheel arbor and batch my work. Most set ups use 1.5 inch hard and 1.5 or 2 inch soft.

Thanks in advance for your input, Biggs (Larry) 3/4" spacing between the 6" wheels will be fine unless you plan on cabbing extra large monster sized cabs in which case you'll probably need a little more room. The DP Genie (older model) I have has 11/16" spacing between wheels. On the older model HP 8" unit I reconfigured I have approximately 1" spacing for grinding larger cabs of things like picture jasper. |
