Mike Blue Posted January 23, 2009 Share Posted January 23, 2009 I dunno Pete, I don't see a broach slot for the drive, idler wheel maybe? Simon, if that's aluminum, I hope it's not going in a rolling mill... There are three kinds of men. The one that learns by reading. The few who learn by observation.

Simon, if that's aluminum, I hope it's not going in a rolling mill... My first thought was a rolling mill as well, but I sure hope thats not the case. I don't think the Al would hold of for very long at all. I'll place my bet on it being an ornimental flag pole holder the the office desk. Have you ever thought about the life of steel? It's interesting to think that you can control the fate of a piece of metal. Link to comment Share on other sites More sharing options...

Simon, if that's aluminum, I hope it's not going in a rolling mill... Mike, I would have hoped you wouldn't have thought of me as so stupid by now Yes Peter, it's a drive wheel for a grinder. The bore is 24.95mm to take a 25mm drive shaft (with a bit of assistance) Ali cost me £6 ($10 ish) 3 inch chunk off a 6 inch round bar. Machining down to 150mm dia x 75mm width Machining was zilch, nada "When our eyes see our hands doing the work of our hearts, the circle of Creation is completed inside us, the doors of our souls fly open and love steps forth to heal everything in sight."

Mike Blue Posted January 23, 2009 Share Posted January 23, 2009 Anyone who can arrange for a really clean wheel like that knows exactly what they are doing. Good job Simon. The comment about the rolling mill bit was tongue in cheek. I do really like the mortar idea, but iron would be best. There are three kinds of men. The one that learns by reading.

Howard Clark Posted January 24, 2009 Share Posted January 24, 2009 Not on the drive wheel. A slight crown is helpful with the idler though. Link to comment Share on other sites More sharing options...
Ken Kelley Posted January 24, 2009 Share Posted January 24, 2009 Does the idler you mention equate to the tension/tracking wheel on my KMG clone? I used one of Rob Frink's tension/tracking wheels and it has a definite crown. Same for his drive wheel which I also used. A straight drive wheel does make sense though.

I used one of Rob Frink's tension/tracking wheels and it has a definite crown. Same for his drive wheel which I also used. A straight drive wheel does make sense though. Yes, on a KMG the idler is also the tension/tracking wheel. I've heard it said that having 2 crowned wheels on a grinder means that they can fight against each other. Only 1 crowned wheel is necessary for tracking and I've got my idler wheel sorted already. it's a slow build because I'm sneaking all the laser cutting and machining on to legit jobs at work to keep my costs down "When our eyes see our hands doing the work of our hearts, the circle of Creation is completed inside us, the doors of our souls fly open and love steps forth to heal everything in sight."

I'm figuring to put at least 2 horsies behind it, Howard, perhaps even 3, I'll make sure it'll get going easy enough another pic to follow and for those that are interested, I've done full AutoCAD drawings (in AC2000) but I'm using them as a guideline only and changing a few bits as I go I've got a pretty good 1 inch belt sander, so rather than go for the 2 inch like the KMG, Iv'e gone an inch wider to give myself the option of running either 2 inch or 3 inch belts.

If you can get 3 hp, get it. If you have 3 inch belts available and you already have a 1 inch grinder for the small stuff, set up for the three inch belts. Horsepower and a wider belt make for more stable grinding and less wibble wobble in your bevels. You'll be able to pretty much rip each side of a knife to shape in a lot less passes. Ooo...get 24 grit and make it really interesting. You could probably sell the steel wool you'll make in the pile on the floor to all the guys making wootz and steel blooms.

What guys are they then, Mike? Anyway, that depends upon whether Col is still speaking to me PS, I don't do wibble wobble on my bevels "When our eyes see our hands doing the work of our hearts, the circle of Creation is completed inside us, the doors of our souls fly open and love steps forth to heal everything in sight."

What are the countersinks on the top side of the base plate for? Link to comment Share on other sites More sharing options...
Simon Attwood Posted January 24, 2009 Author Share Posted January 24, 2009 (edited) What are the countersinks on the top side of the base plate for? I'm really glad you asked that question They were a mistake by the laser cutters. I gave them a drawing and the CSK was on the underside of the plate and they misread it. Fortunately it isn't an issue For neatness I was going to use all CSK screws rather than the hex heads I have seen others use. Because of the mistake on the base plate, I've had to use hex heads, but as it's unseen and will be on anti vibration machine mounts, it doesn't matter Edited January 24, 2009 by Simon Attwood "When our eyes see our hands doing the work of our hearts, the circle of Creation is completed inside us, the doors of our souls fly open and love steps forth to heal everything in sight."

SIXFOOTER Posted January 24, 2009 Share Posted January 24, 2009 OOPS, LOL, no it won't matter. I used hex bolts on the bottom of mine and am looking for a piece of really dense foam to put under it. Link to comment Share on other sites More sharing options...
Ty Murch Posted January 27, 2009 Share Posted January 27, 2009 (edited) wouldn't it be alright to turn this wheel w/in a .005" tolerance just buy turning the dia, parting from the parent stock leaving maybe .125" excess, drill and bore the centerhole, face off one end, facing off the other end to finish thickness, all the while using nonferrous shims to keep the jaws from marring it ??? is this the best way?
