mklotz70 Posted March 29, 2013 Author Report Share Posted March 29, 2013 Went to the Machine Tool Expo in Portland today. Got to watch a Burr King 2x72 in action. Very nice piece of equipment.......but with vari-speed, it was about $3100-3500? Gave me a couple of ideas for later :) 1 Quote Link to comment
fo0manchu Posted March 29, 2013 Report Share Posted March 29, 2013 Burr King's got that industrial look that every other belt grinder has, yours looks way better. And variable speed control boxes are not to expensive. Can't wait to see what you got in store! Quote Link to comment
mklotz70 Posted March 31, 2013 Author Report Share Posted March 31, 2013 Thanks! I'm waiting for vid to upload for the vfd stuff I was playing with. Not sure when I'll have time to edit/post it, but I'll put it here when it's done. I'll put up some pics for now....mostly CAD work Not sure what order these are coming in. PB has been more than annoying for the last couple of months! The new motor had some clearance issues....it was different than the other 56C frame I modeled.......so I modeled the new motor so I could make some changes in CAD. The bolt at the bottom of the motor mounting hole was hitting the face of the mtr. I clearanced the motor face....more on that later......but I needed to design a "block nut" to put in place of the flange nut. Had to modify the small gusset too. The first 12 grinders will have a couple of compromises that I'll redesign and fix in the next batch. That's a big reason for the "introductory price" :) Anyway.... Quote Link to comment
mklotz70 Posted March 31, 2013 Author Report Share Posted March 31, 2013 Some of those are the new one piece vfd mount.....will probably get made in aluminum so that the end user can easily redrill it for whatever they want. Last couple are some prelim work on getting a 10" contact wheel to work on the same arm as the 8". These are more of the 8" and 10" stuff and the fishmouth attachment. I've ordered prototype pieces, so we'll see how they look/work when they come in from the laser cutter. Quote Link to comment
mklotz70 Posted March 31, 2013 Author Report Share Posted March 31, 2013 By the time I post the links, I can't even remember what I had selected. LOL. The single gang box is the $15 switch option. Front gusset is setup to mount it and the bigger, more industrial switch setup of someone really wants the $80 version. That's all I've got time for now....gotta sleep :) Quote Link to comment
mklotz70 Posted April 4, 2013 Author Report Share Posted April 4, 2013 I was all excited about that switch and I've since found a much better option. More on that later....no time to play with it right now. I shot vid while I was hooking up the vfd. I chopped a lot of it out.....like most of the motor wiring. There's no guarantee that anyone else's motor will be the same. Anyway.....here's the vid. It's mainly to show those that would like to go variable speed, but aren't familiar with vfds and 3ph motors that this isn't rocket science. But....you do need to be careful and do it correctly or you could smoke the motor, vfd, or yourself. Quote Link to comment
mklotz70 Posted April 6, 2013 Author Report Share Posted April 6, 2013 What's better than one laser cut grinder? 12! :) Quote Link to comment
mklotz70 Posted April 7, 2013 Author Report Share Posted April 7, 2013 I put together one of the tool rests.....I like it! :) Quote Link to comment
yello620 Posted April 8, 2013 Report Share Posted April 8, 2013 Mike, got to check one of these out at the swap meet, Talked with Dave for a bit. That entire assembly is pretty damn cool. Really like how it is all bolt together and interlocking. Quote Link to comment
mklotz70 Posted April 8, 2013 Author Report Share Posted April 8, 2013 Thanks Jason! We're pretty pleased with it. Not extremely happy with some of the laser cutting.....could just be normal to laser cutting. As cool as all the holes are, they put a lot more heat into the part and so the parts have some bow to them. Not an issue with some parts.....def issue with others. I wouldn't mind trying one without the holes. Anyway......I've got waaaaaay too much time into this project! I'm anxious to get back to some of the others. :) Quote Link to comment
mklotz70 Posted April 20, 2013 Author Report Share Posted April 20, 2013 belt grinder related, but the vid isn't specific to the grinder so I put it here.... http://community.ratsun.net/topic/8292-lets-see-some-machine-work/?do=findComment&comment=903402 Quote Link to comment
]2eDeYe Posted April 22, 2013 Report Share Posted April 22, 2013 Do you have a parts list for the purchased components? :D Quote Link to comment
