    Default Surface ground stones, a new set.

    I figured I would post about this in these forums. I have not posted for a while.

    I ground a set of stones for one of our members here and figured I would make a video about it. I also wanted these stones to make it home ok, so I 3d printed a case for them. I hope they make it to their destination in one piece. You never know with USPS.

    In either case, if anyone is interested in how I ground these stones. Well I have a video.

    I contacted Rob Renzetti about grinding me some
    but he seems slow about getting going to do it.

    No diamond wheel? No coolant? No fancy feathered hold-downs? Well, that certainly simplifies the job!

    I would like to see more of you vac / dust collector set up.
    What kind of vac motor did you use???

    How long can you run a vac motor before it overheats??? Some grinding jobs can take a fair amount of time.... like those two stones.

    There is a diamond wheel mounted. I have done a set with coolant as well as with soaking. Both make a huge mess and the outcome of the stones is not as good as dry, Stefan mentioned he grinds them dry now as well. Avoids the dry time etc. The only down side seems to be that the diamond wheel is wearing more. No big deal. As for the hold downs, well I will build a set of those eventualy, for now my shop ground parallels and 1-2-3 blocks as well as my new to me angle plates are working a-ok.

    The vacum I used is a dirt devil stick vac, a cheapie. It seems to not run hot these days, I used a bit of oil in the bearings. Being that all the crud ends up in the separator, and none ends up in the filter it is also not so taxed. As always your mileage may vary. However for me its a good balance between noise, heat and efficiency. Is it perfect? No way, but it seems to do a reasonable job.

    I am thinking about doing a run of these at some point. The set above was made for a forum member here. He is more than welcome to share any thoughts or criticisms even if they suck its ok to get the criticism back and possibly think long and hard about how to improve my skillset. I am still learning every day and hope to never stop.

    OK, thanks.I was wondering about the duty cycle of these vac motors. I'm still playing around with dust collectors for my two grinders and am always looking to improve what I have.
    I'll start a thread on what I have when I get some pics.

    I would definitely be interested in a set, having no grinder of my own
