Making adjustable miter gauge runners
When making sleds for the tablesaw or to suit comparable information slots in different instruments, I’ve at all times made the runner myself. The benefit after all is that they’re fast, simple, and low-cost. They by no means depart me ready for the UPS truck to reach, and there’s satisfaction in having made them myself.
Alternatively, being made from hardwood, they’ll swell to a tighter match or shrink to a looser one in response to adjustments in humidity. These adjustments can have an effect on ease of use and accuracy. So, right here’s a strategy to make hardwood miter-gauge runners in your individual store which can be adjustable to an ideal match even while you’ve had prolonged intervals of maximum moisture in your woodshop and your runners had been made in a drier time. Or vice versa.
Use hardwood of the size you need for the jig or sled you’re making. In my case, I used cherry and milled it to the next dimensions: 3/8 in. thick, 11/16 in. vast and 13 in. lengthy. Use a drill press and 11/32-in. brad-point bit to drill holes alongside the sting of the inventory. Be sure that the drill is centered within the inventory. Utilizing a fence on the drill press will give extra correct outcomes. Mark and drill these holes 1-1/2 in. from the tip of the inventory and at middle on every bit. The holes needs to be drilled 1/16 in. deep permitting the pinnacle to sink into the inventory. Use the depth cease on the drill press to manage depth.
Subsequent, put a 5/32-in. drill bit within the drill press and modify the depth in order that the drill will cross utterly by means of the inventory. Use the fence and the middle of the beforehand drilled gap to information the position of the inventory on the drill-press desk. Use an 8-32 faucet to type threads within the holes for the plastic screws to suit. I mounted the 8-32 faucet in a cordless drill and lower the threads in every gap, slowly out and in to maintain from stripping the threads. The faucet is meant to be used on steel so watch out to not drive it in to date that it strips out the threads.
For those who use 3/4-in.-long nylon screws as I did, you’ll want to show all of them the way in which into the inventory after which use the stationary belt sander to sand them flush on the alternative facet. Use a screwdriver to regulate them for an ideal match earlier than mounting them to a sled base. After mounting you may modify the screws for a clean friction-free slide by means of the lower. The nylon screws will see to that. The nylon screws I used are from Amazon, Hillman inventory quantity 59463-L.
