It’s been a while in the making as life keeps getting priority, but I have now completed my new sled, and currently sit here in trepidation about whether it’ll work or not!
Actually, I test ran all three axises a month or so ago and all checked out, so I contiinued with the build. I’ve cobbled together my sled and x-axis lift pretty much from scrap and off cuts. I found the lead screw for the lift from a scrapped drill press depth stop (nice brass nuts!), two microswitches from an old PC mouse, the STOP button is from a childs toy (they didn’t want it anymore, honest!) and the stainless ring was part of a cot, until I turned it into a circle. I found a couple of old bearings in a spares box and hey presto!
The extract attachment is from some other tool, but seemed to fit well. Most of the sawdust spoils will fall due to gravity towards the vacuum. I’ve also put a polycarb screen around the router and lift arrangment to help contain dust and chippings a bit.
Looking through a thread earlier today I realised I’d neglected to add my weights, so I popped those and now I think she’s ready to go!
I’ve got a steel cable I intend to hook up to the chains a few links away from the sled so that in the event of a failure of attachment this should catch the sled from a disasterous fall.
I’ve included two microswitches as hard stops for the x-axis, and the PANIC STOP button, which are connected to a ribbon cable running back to the Arduino. If anyone has any ideas as to how I can connect this up and make it work I’m all ears and eyes ;¬)
You can just about see the microswitch behind the end mill (gotta love hot glue!).
