So, sometimes old warbly tools are worth more as trade ins for discounts on newer cordless equivalents than they are as functional tools. I’ve seen similar bins of old tools at the DeWalt factory service center, where I once visited to get repair parts for a favorite (discontinued) Porter Cable sander. The customers just dumped their old saw in the bin, and were then handed a ticket worth $100 off a new replacement saw similar to the (slightly modified) saw shown above. No one checked to see if these old saws were working or not as they were brought in. At the most recent Makita Driving Innovation Tour event that I visited to capitalize on similar discounts, there was an entire pallet of decrepit, dilapidated worm drive saws, and I watched as guys kept bringing in more saws, which then overflowed to a second pallet sized bin. The year, Makita from time to time has offered a $100 trade in value discount if you bring in any competitors saw in exchange for the saw shown in the photo above. Lowes doesn’t stock it.īTW, if you find that even with correct lubricant your $15 Craftsman industrial saw still doesn’t sound or feel right, it might yet be worth a $100 discount off of a new replacement cordless saw that looks and feels just like a worm drive saw, only it is a direct drive model that doesn’t require any gear lubricant. Mixing grease bases and lubricants can have other deleterious effects, as some chemical constituents can react with each other when heated (in use).Ĭlosest Home Depot is 30 miles in the opposite direction of most of my travels. The high sulphur content of typical differential gear lubricants will smell repugnant when using your saw. The real problem with using rear end differential lube will be the SMELL.

The worm drive gear lube is definitely more viscous than most rear end differential lube viscosities sold today, which are typically on the lighter end of the weight scale for fuel economy (ie 75W-90 vs 85W-140). One only needs to replace the retaining screw that comes with the Skil fence (SAE threads) to a metric screw… which I believe is an M6x1.25, in order to thread into the Makita magnesium base plate. It’s kind of cool actually, to have such immediate, ubiquitous, and after hours access to the most frequently needed support parts for the Model 77.Īnd by the way, the Skil rip fence works and fits perfect with the Makita Rear Handle saw. Home Depot also stocks a replacement cord with built in strain relief, and a trigger switch… all in support of the timeless Model 77 worm drive saw. Within the last year, I picked up rip fence, a tube of lube, and a sky hook… all genuine Skil brand… from Home Depot. The tube might still say S-B Tools on the back, perhaps left over trademarking from when Bosch and Skil were partnered tool brands. You can pickup a tube of genuine Skil branded worm gear oil at your local Home Depot today, for immediate satisfaction of your curiosity.
