Power Hacksaw Blade Tension

Instead of windows (which I find to be a nuisance when the sun is low anyway), go for skylights. Nice diffused light from above and more wall space. Doors...

Whatever it is, it looks like a really handy piece of kit! Assuming that is a grinding wheel mount and the spindle speed is suitable, it could be used...

Thanks all!

John, I know what you mean about both strokes being pull strokes. I don't know the logic of choosing one over the other, apart...

Hemingway have supplied a casting to do this for decades - called the rock of Gibraltar toolpost: http://www.hemingwaykits.com/acatalog/Gibraltar_Too...

I have a small horizontal mill, similar in size to Dian's. Mine is an Adcock & Shipley 1-ESG. It has a 40 INT taper, and a lowest speed of 25rpm....
