Two-wheel grinders

chickens and Aerosmith...perfect grinding background...
looks like you have a fine grinder there..

I am still hard to belive that I made this and it's working!

I have been grinding on a two wheel grinder for the past 20 plus years and do just fine on it but I am thinking that I would like a three wheel grinder just for the option of putting a grinding rest on it. I think that the extra support will help me out as I am getting older.

Oh, I will make myself a work rest table. the same as no-weld-grinder knife rest. Telescopic construction, so I can adjust it to the flat platen or to the wheel. it is just 4 inches from the center of the wheel to the lower end of the platen.

This is the second grinder with setup. My friend Gogo is the owner. He provided the main parts for the two grinders - contact wheels and bearings.

what are you using for a tracking wheel? parts list maybe?

 

[knifemaniac]

The tracking pulley is from palete transporter. Small ones on the forks. Hard rubber - it holds 2 tons of preasure with two bearings installed inside, and you can easly make it bumpy in the middle by holding the wheel with bearings on a shaft and grinding while it's spining.

Now I have aluminium wheel, and the palete transporter wheel is spare part. You can use those wheels for flat platten attachment for three wheel grinders. I will make pictures soon of the details.

why did you switch to an AL. wheel? is it also a caster? just trying to learn from others experiences

 

[knifemaniac]

Here is the rubber wheel (or polyurethan).

And the aluminium one.

I have both wheels now. In case oh heating the aluminium wheel cools the bearings, but both wheels are doing fine.

One more add to my grinder. A disc grinder to the same shaft. Now it is a combo grinder! It is 1cm thick textolite (micarta).

Cool idea! I thought about doing that in my grinder plans, but it was just too confusing to try to do that at the beginning. Plus, there's always upgrading later.

What size disk is it?

 

[knifemaniac]

180mm diameter. I can glue wet/dry sandpaper for finishing solutions. It is great for finishing flats. I am think to glue velcro disc for using sandpaper with fuzzy backing. Someone uses velcro on disc sanders? They uses those for angle grinder rubber finishing discs. A lot faster to change grits.
