Does anyone have a suggestion for a surface grinder attachment that would fit my pheer 454? I know I could build one but I just dont want to get $500 into building one, ruin it, and still have to buy one.
Thanks very muchI looked up the Pheer 454 grinder - looks like it's a standard 1.5" tooling arm with dual slots. If so most any of the commercial SGA should fit just fine. My STRONG recommendation would be the Reeder SGAStacy on another forum has one and is impressed with it. While I don't own one, I've looked at it pretty good and am also impressed. "IF" I were purchasing a commercial SGA it would be my choice hands down. The OBG https://www.ebay.com/itm/263146335672? is less expensive and should work ok. BUT - the Reeder is a step above.
Something is wrong if that's the best you're getting out a SGA. Here's what I've got in past, I think that's a petty chef with blade around 5" to 6", then with a 4 to 5" tang giving around 10" overall length:I mentioned above were 2-3 thousandths over a 5" span/piece, and 3-5 thousandths over their 10" capacity.
If you are taking a really heavy cut of .005" or so then you will have that problem with a soft wheel. The trick is to make the last couple of passes down around the 1/2 thou to 1 thou and the softer wheel isn't so much of an issue. Some folks who don't wish to take shallow cuts at last will use a 90+ duro wheel and that works pretty good.the issue of the contact wheel(s) being too soft for the application, and the work piece/steel you're grinder comes out with a convex face,
Yes, it's one of the very early homemade SGA (Surface Grinder Attachments). I built it a yr or so ago when we were first learning about building them.Thats super for a SG attachement! (I assume that's what you're talking about?) That shows that it is a viable option
