We all need to grind and iron or chisel sometimes. I don’t own a grinder and tbh it just looks rather tricky grinding a square edge on a wheel far narrower than the blade itself. I am also not convinced if I like the idea of a hollow grind, seems that particularly with a shallow grind it doesn’t leave a lot of meat behind the cutting edge.
Sometimes I do remodelling/construction jobs and my chisels suffer… they are $5 chisels but I’m too tight to buy a spare set, always thinking they will be my spare set when I finally shell out for a “real” set. In fact part of the reason I have held off on buying a quality set of chisels is feeling I would rather be established and comfortable in my sharpening set up before having to brave sticking a $40 blade into fast moving grit.
So the other week there came a moment that I decided to sort this out. Like most shop projects it was a low/no budget, dig out/scavenge/adapt what I can job. I had a piece of thick(ish) aluminium right angle profile and I decided to butcher a short piece of aluminium fence extension which came wiuth my bandsaw which I hadn’t found a use for. I had to buy a few nuts & bolts as after tipping out all my random nut & bolt boxes all over the bench and searching through I discovered none of what I had were just what I needed.
The tool bar itself has t track for which I may make some jigs to hold different tools. It slides back and forth in T slot on the two side brackets which are bolted through the sides of the sander platform and rotate to set the angle, locking with wing nuts. I did a simple sketchup outline of one side and used the rotate tool to work out the required movement front to back. This gives me the full range from 90 degrees to square an edge through to 15 degrees with the bar always positionable at a nice distance from the belt. The bar can be fine adjusted for height and level with the bolts/locking nutswhich are tapped into the sliding “Ls”.
All in all it works well, cost me pennies and I now have all my edges back in good shape.
