48willys Posted October 16, 2008 Share Posted October 16, 2008 Over the weekend I found a old pedal grinder like this one This one is rusty but complete ,the wheel is out of round or it needs to be balanced,but he is asking 75.00 for it.Sounded a little to much to me for the work i'll have to put in it to make it useable again,but what are they really worth?

the_sandy_creek_forge Posted October 16, 2008 Share Posted October 16, 2008 Around here (Central Illinois) usual going price at auctions is between 50 and 100 dollars, depending on condition and number of antique collectors who happen to be at the auction. So that price sounds about right. My personal opinion: being able to sharpen (axes, knives, hatchets, mower blades, etc.) on a natural stone is worth that price. The two I have (one complete with metal tube frame, one just the wheel and mounting hardware for a wooden frame) are both slightly out of round. Since they are run so slow it really doesn't affect my using them that much. Also consider a 14" grinding wheel, Aluminum Oxide, from Mcmaster Carr will run you in the 100 dollar range, and it is NOT a natural stone wheel. -Aaron @ the SCF Link to comment Share on other sites More sharing options...
48willys Posted October 16, 2008 Author Share Posted October 16, 2008 Thank's ,I guess they are worth alittle more than I thought.I think I'll get it when I go back.At least it's not a pile of junk like all the ones I see around here. Link to comment Share on other sites More sharing options...
HWooldridge Posted October 16, 2008 Share Posted October 16, 2008 That one is in relatively good and complete shape compared to some I've seen. I'd definitely pay $75 for one in similar condition. Link to comment Share on other sites More sharing options...
48willys Posted October 16, 2008 Author Share Posted October 16, 2008 That picture is from Yesteryearforge in the gallery(I only used it so everyone would know what I'm talking about).The one I'm looking at is made the same only rusty and needs alittle work to get it back to working.

Thomas Dean Posted October 16, 2008 Share Posted October 16, 2008 I paid $50.00 for mine but it had a bad flat spot on the wheel. I had it water cut to true it up, $25.00 for that. (It still measures 18"+) So I have $75.00 in mine. Although I have not used it, the kids that come into my shop (no matter their age;) ) enjoy sitting at it and playing. I have sharpened a few drill bits with it. You might think about offering a little less and see what they say.... Link to comment Share on other sites More sharing options...
CurlyGeorge Posted October 17, 2008 Share Posted October 17, 2008 (edited) I have the stone with the shaft through it and nothing else. I paid $10 just for the stone, and I'm pretty sure that it's out of round. Edited October 17, 2008 by CurlyGeorge Too many O's in the amount!!

yesteryearforge Posted October 17, 2008 Share Posted October 17, 2008 I actually have eight of them ( all in as good of shape as the one in the photo, one is new old stock ) and i paid between 50 to 90 dollars apiece for them, I have several other petal type grinders too ( I really like the inguinuity some of these things have built into them Mike Tanner Link to comment Share on other sites More sharing options...
Wayne Posted October 17, 2008 Share Posted October 17, 2008 I have three stones so far but only one set up with a hand crank which I take to demos, If i need to sharpen or polish anything up I invite the kids to turn the crank for me. If I let it go on I could be sat there all day with a big queue of kids just waiting to have a go........... Link to comment Share on other sites More sharing options...
Finnr Posted October 17, 2008 Share Posted October 17, 2008 Just located one at one of my favorite antique dealers for 15 dollars. Stone, shafr but the crank is broken, Wonder if I can locate a blacksmith to fix it? LOL! The stand is nothing to worry about I'll whip up a stand and pedal.

CurlyGeorge Posted October 17, 2008 Share Posted October 17, 2008 Way to go finnr. Now get the stand (and seat) built so that I can steal the design!! LOL. Link to comment Share on other sites More sharing options...
Doug C Posted October 18, 2008 Share Posted October 18, 2008 I have one of these on the back porch. Came off the family farm. I would like to use it but don't want to try until I figure out how to use it right. Do you use it wet or dry? How fast / how hard do you pedal? Anyone got any tips?

DanH Posted October 18, 2008 Share Posted October 18, 2008 Mine has a small funnel-shaped attachment hanging above the wheel. Put water in and it drips out the hole in the bottom to wet the stone while working. Link to comment Share on other sites More sharing options...
blacksmith2015 Posted September 24, 2019 Share Posted September 24, 2019 any one know where the center hardware can be had. Have a stone that has the shaft and hardware to grip the stone missing. Can do the bearings. Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted September 24, 2019 Share Posted September 24, 2019 The center hardware is not hard to make if you have a forge. BTW ... Welcome to IFI. Have you read this yet? READ THIS FIRST Link to comment Share on other sites More sharing options...
blacksmith2015 Posted September 24, 2019 Share Posted September 24, 2019 Yes have forge and welder. Have been unable to find much except price of stones. Could get large reddie bolt to make shaft from. No blueprints or photos to point the way. Link to comment Share on other sites More sharing options...
pnut Posted September 24, 2019 Share Posted September 24, 2019 Check patent applications. They usually have a diagram. Pnut Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 24, 2019 Share Posted September 24, 2019 I've seen several that used an Old buggy axle with round ends and a square middle and some wood wedges, (have to cut it down and round off the Sq cut end.) Assuming this is a 1 tread grinder and not a "bycycle" grinder. Link to comment Share on other sites More sharing options...
Kozzy Posted September 24, 2019 Share Posted September 24, 2019 Common around here seems to be a pretty sloppy spindle shaft and instead of standard wedges, they use leather to pack out any gaps. I assume that one benefit of the leather is a very tiny bit of shock relief, possibly helping the stone not crack as easily at the bore. It's also a pretty simple way to install things--wet the leather strips down and they can pack in quite easily. Here is an example of a bit of leather inserted in one in my shop. I know of several others where this method was used. On this one in my shop, there is a square wooden filler block in the square bore of the stone with a simple round hole for the spindle. Some farmer made a wooden disc to act as a washer to hold the wheel in place when the nut on the shaft is tightened. The wooden disc also helps prevent stone cracking in the event that someone gets over-zealous in tightening the nut. And the other side of that one just so one can see the rest of the shaft with the original steel plate washer. On this side there is an "upset" in the shaft to make a bulge and act as a stop when the nut on the other side is tightened. Link to comment Share on other sites More sharing options...
