The readily available flat sided 5/16 T-slot bolts will also work provided two thickish washers are used like this. Knobs for 7/16' bolts are hard to come by. The main slot width is 7/16' and most 7/16' hex bolt heads are held reasonably well by the lower slot like this. Sorting out the bolts took a little sleuthing. Lots of razor sharp shards of Al are reduced so use PPE and a DC is you have one. Use a blade with the most number of teeth and take it slowly. Can you suggest another place to get some tracks BobL?I used this one from Capral (highway road sign track - part number 801928) for my Bandsaw sled, but you have to buy a 6m length ($35).īTW you can cut this stuff with your table saw.
