anyone made their own grinder???

[Von Gruff]

Been a busy day and have it all to a stage now that it just needs the drive wheel turned and the wheels to arrive from the US so in a couple of weeks I should be able to get it tunred on. The tool rest will not get welded on till the wheels arrive so I can center the rest against the belt

This is how it sits for now though.



I will drill out the holes for the idler wheels when they arrive



The handle of an old gate valve made for a good tracking adjuster wheel and a length of pipe flatened and welded to the bolt head will allow for tightening up on the two sliding tool heads.
Here I am holding the tensioner down against the gas ram stroke



With it released it shows I have a goodly amount of travel



Then there is the tracking aduster screwed all the way out to track one way



And all the way in to track the other

@Von Gruff: I saw your thread on this grinder over on castboolits forum - looks good. I've always had concerns about how to press the spring down, but I see the handle you've got to give leverage. Good idea! I like it. That design sure takes care of any flex in the tension arm. Where I to build another grinder I think I'd look seriously at this design using your leverage arm to press spring down for belt changing.

I guess I got the idea for the handle from the leverage system on my Lyman 4500 Luber.
As well as the paten tool head I have a 12 in contact wheel and will have an inch dia one and on the other end of the shaft I am going to be able to have a 375mm dia (14 3/4 in) as there are readily availabe emery discs of that size here (for shearing shed use) and then a second disc made of 2 pieces of 3/4 in ply that I will glue a length of leather round the edge then load it with green compound so I have a spinning lap for the final edge on the blades. Hope to have all this up and running in about 2 weeks when the wheels arrive and the guy here finishes the welding and a bit of turning for the inch dia wheel.
