More of a tool review than an update but I figured it might help someone else on the thread.
As I inch my way to concrete being poured, I am now at the stage of capstones/pad border. Since I am attempting to perfect something built out of imperfect blocks, I got the dumb idea of grinding the top tier of stone in an attempt to allow the caps to lay down a little cleaner. From my experience of cutting and grinding with a 4” abused grinder, I got the idea of using a larger 7” grinder. For all of you that poo poo harbor freight tools, you can get everything I mention here at Home Depot for substantially more money. I almost went that route but I considered that prediction of using these items again in the future.
Found a 7” grinder at HF for $69.00
Hercules universal shroud/dust pickup $37.99(worth every penny)
7” flesh eating chunky disk for $35.00
7” finishing disk for $35.00
Home Depot
Grinder $129.00
Shroud $70.00
Flesh eating chunky disk $105.00
Finishing disk $59.00
The grinder worked fantastic and the dust collection shroud was worth every penny. It was so effective that it captured so much dust and particles that it ruptured the HD 16 gal shop vac bag and filled all available space with fines. Was so heavy I had to use the leg lifting technique to off load to the garbage can.
Quick and effective way to level imperfections in blocks.
Discovered that due to the velocity and coarseness of the debris, it quickly wore a hole in the new bag and filled the vac up with fines that were more like talcum powder, or silt from the Plya for those that consider themselves “Burners”[emoji6][emoji2957].
My solution to this issue since bags are $11.00 each and I don’t want to use one up every grinding session, I will try out a buddy’s whizbang super dust sucker-upper dealio. This little item will go between the grinder and the shop vac and hopefully divert a majority of the debris. Will find out tomorrow.
I also reinforced the actual shop vac bag with some military grade duct tape hoping it will toughen up the bag’s wall where all the debris comes in at high speed.
Cheers
