Great example of working through the problem! I had no idea that you could "force feed" a cardboard template into a printer w/o it freaking out! That alone is something VERY useful!! Thanks Steve
Very interesting series of deduction! Nice video, admire how you never succumb to take the easy way out and keep investigating and you always do it right. I’m sure that comes from like you say, you have seen what happens when people do it wrong.
You might also look for blotter material in the office and art supplies world. Desk blotters used to have a piece of thicker paper covering the surface of the blotter holder that is the typical work surface of a desk. Hard enough to write on but soft enough to indent and rebound. There are also ink blotters that were used to press in a rolling motion over signatures and other writing while still wet to absorb the excess ink from quill and fountain pen writing. You still see ink blotters used in movies - a cord of a circle with a handle a couple inches or so wide with a paper over the face to pick up that extra ink and speed the drying.
After your last video, i did a lot of investigating and found the same stuff. I also came acros a group talking about all this and someone that said he used to work for Norton, said they used basic cardstock to make the blotters. So if i were you, i get some standard card stock, the thickness of your choice and get a laser cutter and make your own, as that's a lot easier than cutting and punching out by hand. I also saw something that said, when changing grinding wheels, you should always inspect the blotters and they should be changed if damaged, so yet another reason to have a few in stock; f you change wheels on a regular basis.
I'd make a fixture. A center boss to locate the blotter blank, a punch position, and a locating pin some odd number of holes away from the punch. I haven't worked out the math, but I think it doesn't matter what number of holes away, as long as it is an odd number for an even spacing like 40. I'd start with 19. Punch, rotate, punch, repeat. Of course if you have a spin indexer it's the same process.
God I hope I don't ever need that many :) Think I'm going to also see if the laser will cut them out from a print.. .Several people have said they think it would work well....
Look into Rite in the Rain, a company that sells waterproof paper. I found this product before my paramedic days when I was in the US Coast Guard. We had forms that we carried on the boats and they would swell from the damp environment. I have seen this paper displayed in a water bottle full of water, No degradation. Not sure what the measurement of it is but they, offer a card stock. Their part number is NO HW8511. It is listed as a 100# paper and by comparison the printer paper they offer is 20#. Might be a waterproof source of material. Just a thought. Good luck either way.
@@10swatkins I did some more poking around and found that they have a 175# weight paper also. I know their standard printer paper. Works well but have no experience with the cardstock stuff.
@@mikeycoop66 I just opened a pack of card stock I had sent to me... It's 160 weight and measures .024. I'm going to spray it with Thompsons water seal and see what happens :)
I thought you were looking for. " Perforated Blogger " 😂 i couldn't see how hard that would be to find !! Most of them have Piercings everywhere !! 😂 🇨🇦🤓🤟
Thanks Steve for more info I will ever want to know about a grinder blotter. All kidding aside I am glad you were able to find some info to help you make a safe attachment to run the grinder on that DoAll (fingers crossed) Thanks for sharing another entertaining video.
I went down a similar rabbit hole with the DoAll G-10 grinder that followed me home. It doesn’t have the “Cool Grinding” hubs on it but the blotters had deteriorated on the wheel that came with it. I had to satisfy myself with the beer carton solution. I prefer IPA’s myself. That wheel was a 60 grit and I ordered a 46 grit from KBC tools and it seems to be better suited to the projects I have on hand. I have manual for the grinder and some of the original sales brochures for it which make enjoyable reading.
I did a search for grinding wheel blotters and got nowhere. Usually I’m pretty successful with internet searches. Not this time. The fact that McMaster-Carr doesn’t carry blotters tells us something. Like: most people don’t bother with them. But I’m with you, Steve. They serve a purpose. Find ‘em or make your own. Grinders are scary machines. When I start my 1/2 horse bench grinder I stand to the side, out of the “kill zone” and let that wheel run unloaded for about 30 seconds before I put any load on the wheel.
I was really surprised that I could not find them either.... I mean with so many companies under the rules of OSHA it looks like they would be a common thing that OSHA inspectors look for....Hell there is probably a rule for toilet paper!
Norton Blotters are typically .020" thick. I've measured them and Norton has thus far been unable to provide them as an aftermarket item. The paper is supposed to be waterproof as well. I've been making my own for awhile since you can't get them even for OE wheels that don't have them or they've worn away. If blotters are this important and they are; you should be able to source them.
@@10swatkins No telling Steve. I've got a few CGW wheels and they just aren't the same quality as Radiac or Norton. The Norton wheels typically run truer and are well balanced. I just have several old wherls that I've had to make blotters for and it ought to be just a matter of a phone call to get a few extra but so far it's been a real chore.
I worry about the centrifugal force on a wet cardboard it would think that a velcro gasket paper might be a better blotter what if you intend on making your own how about taking some scrap metal and making something on Bob see you can punch them out and then come in with a second operation of your punch to punch the holes through you could use needle bearings wedged into a third plate to punch them through
For some unexplained reason, only the 'Dislike' button is available to me. I suspect people are hitting (without looking) what they believe to be the Like button. Keep up the good work!
My like button has not appeared on any video since my comment. I know someone is updating the program. I'm sure it'll get repaired soon. I just didn't want you disheartened is all.
Surprised you didn't call up Clark from Windy Hill and ask him to cut you some out on his fancy 40w laser cutter, it would make short work of the perforations. We use Pig Mat for blotters on the surface grinder we have at work. 👍👍
I have a cutter here, only a 20W though... In working with it I found it really burns the edges of material instead of a clean cut.. How thick is the pig mat you use?
Did you look into them? They want to custom print blotters for you. They say they offer blotters but you have to contact them for a quote.... Another rabbit hole :)
@@RambozoClown They had one listed as "Produced from cushioning material which meets the industry standards for compressibility" then they had the .010 thickness listed as.... "An economical alternative to the White Cushion Blotters. Made from high quality .010 thickness material" No idea what Industry Standards they are referring to or how thick the cushioning material is... The .009 thickness "blotter" on the CGW wheels was really thin.
Steve I have 2 aluminum centrifugal coolant washers basically they have no name but they have the radial trough with holes around the periphery on the blotter side of these there is a annular relief grove where the holes go through the aluminum piece. These pieces go against the blotter and the wheel hub sandwiches it. So the holes in the blotter on the wheel you are talking about don’t have to line up that annular groove would line up with the holes in the blotter, I wish I could send a picture of these to you instead of this long drawn out explanation thanks for all the videos tell don hi. Ed
How about gasket material. Fel-pro has a grey gasket material you can buy in a sheet. I'm not sure but it is at least .020 to .025 thick, and has a lot of squish factor.
Have one... I think it will burn the thin paper too much... What I think would be go is something like a vinyl cutter that uses a knife to cut... Might not make the holes too well though...
If you want some pristine paper check in your area to see if there is a packaging printer. They most likely would give you a couple of large sheets of paper in any gauge you want.
Hi Steve, my 24th edition of Machinery Handbook states, Blotters or flange facings of compressible material should cover the entire contact area of the flanges. No other info.
IT is a deep subject with little info :( The .009 thick non compressible "label" on both of the CGW wheels I have for the machine leave about a 1/4" of the wheel touching the outer flanges.... One of the reasons I wanted a larger blotter....
Generic replacement blotters were discontinued a long time ago because they lack requisite warnings regarding use and limitations for the grinding wheel. So you can thank our litigious society for their demise. Consequently, we now have to throw away perfectly good grinding wheels when their labels/blotters come off or get damaged. In regards to your situation, if your going to use through-hub coolant, you will need to make your own blotters. None of the cardboard substitutes that you mentioned should be used. Your blotters MUST BE WATERPROOF and cardboard packaging isn't. OEM blotters are typically made from adhesive backed thermostable paper. Avery #64506 labels should work well for your application. Also, you can use your diode laser to cut them out.
You could... About the only thing it would help is maybe water proofing... Old hands that have done this for years seem to think the cartons work well. Hell maybe they are just cheapskates :)
Hi. Nice work. You made a drawing in a cad and printed it out. That is nice. Specially the part that your printer accepted the carton from cereal box. On the other hand do I remember correctly that you have/had a laser cutter? Or was it just an engraver? If you could cut it with laser perhaps it would be easier?
Don't know how it will burn the paper.. When I return from the Z Bar Bash in a couple of weeks I'll see about it... My cutter is not as easy to use as Clark's so it might be a little more learning curve...
I have snapmaker 2.0 and I have used with 1.6w and 10w laser to cut paper templates and stencils. I don't have air assistance and sometimes edges can be a little "burnt" but it happens mainly with thicker paper. If focus and speeds are ok then outcome should be good. If it works it can make life a lot easier for making also some gaskets etc. Only CAD will take more time than making the gasket on site. Also there are hacks many youtubers take a photo of thr thing they need and use this as a trmplate in cad. If you need more than one, it can perhaps be a good way to go. All the best and have a nice trip :)
You need to get a sister Juliet high definition cutting machine that can cut the finest detail in different materials Egginton HTV vinyl cards tock stickers craft foam and more
If you still have that laser engraver, couldn't you burn a blotter with the engraver. the information regarding blotters sounds like important info. KOKO!
Also, what good does the little bit of extra coolant do getting behind the blotter? And how do you ensure the holes on the blotter are actually lined up with the holes in the hub? The whole thing seems like a marketing gimmick that doesn't do anything of substance in the real world. There's a lot of grinders out there (they make them in factories every day), and if none of them have this feature anymore, it couldn't have been very useful
The holes line up as you assemble the hub, not hard at all... Also the wheels they are used for are very porous and the coolant does actually make it's way into the wheel and is slung out the cutting edge... Not sure it really helps anything though...
