But I’ll be damned if they’re not perfectly parallel!
With the new garage set up, I wanted a better way to mount my presses & vice than just bolting them through the workbench. I was pointed to Rockler & their aluminum tracks and decided that I would give them a shot. The idea was route a channel for the tracks into the bench then permanently attach the presses / vice to a good piece of plywood. Those then could have the t-bolts attached to them so I could slide whatever I needed on or off the bench. If I need the whole bench, I no longer have to unbolt the damned things for the space.
This, of course, meant routing two perfectly parallel channels into my new bench. Nerve wracking to say the least, but minus one glitch where the guide popped loose (the back of the bench is practically flush with maybe 1/2” hanging over to clamp onto) and a little chatter, it worked pretty damned good.
Those rails aren’t going anywhere. A bit of wood-filler should cover up the ‘oopsie’ and the end of the channels.
Now, I measured twice & cut once on the plywood to hold the presses / vice, but measuring doesn’t do diddly when you cut in the wrong direction, so I ended up screwing up the mounts. Luckily it’s only $8 for a sheet of plywood so I’m not out a ton of cash. However, I did mount my Hornady just to see how it would work using only one rail and I have to admit, I may have been able to just get away with a single. This damned thing doesn’t budge.
I’m far from a handyman and things I do may not be the prettiest but I do take pride in the fact that I’m capable of doing such things.
