Homemade 12" Disk Sander (Part 2)

in my last video I started building a new disc sander and so far it works pretty well but I still want to change several things and I also need to build an enclosure for it right now the disc spins at about 1,400 rpm but I wanted a little bit high about 1700 so in order to do that I need to change the pulley ratio the pulley attached to the disc needs to get smaller so I put it back on the lathe and turn it to the required diameter I use a roughing gouge to remove the majority of the material and then I used a parting tool and a little detail tool to get the right pulley shape for the v-belt as you can see making a pulley out of wood is really not difficult and saves you a lot of money I could have just made the disc pulley smaller to get the right rpm but then I would have to mount the motor a lot higher than before so I worked out a pulley ratio that makes the right rpm and doesn't change the position of the motor that much but that also meant that I had to make a bigger motor belief so now with higher rpm that second nice you come here is the roller right wheel coming then I focused on making an enclosure the back is just screwed on nothing fancy here there is also a little cover in the front under the table that should improve dust collection and protected this from below so next thing this sander needs is a cover that covers up the disc around here and the belt so I drop the arc for the disc on a piece of plywood and next I'm going to cut this out on a bandsaw I could have just cut it out the end but I decided to try my separately so I put in the right insert then adjusted it to the right radius and locked it in place cutting the arc is now really simple I just have to slide the piece into the blade and then turn it next I gonna cut off the corners and sent them to the line but somehow this didn't really work I recognize that the buoy came loose so I had to fix that problem before I could go on so far there were two set screws through the pulley which pressed onto the shaft but obviously that friction was not enough so I drilled a hole into the shaft with the pulley in place I had to remove the cuttings with a magnum very often this flange is made from some very tough steel and fortunately Ahab a driller that cuts through that stuff next I took one of the set screws and grinded the end a little bit so it would fit inside the hole on the shaft then I threw a peg in position and it fit the hole the set screw itself is mounted in a slightly under sized hole through a pulley and it cuts its own frets in the wood and I also put another screw next to the set screw and its head prevents it from coming loose again once that was done I could continue on making the cover I transfer the corners onto the back piece cut it out and make sure that it fits around the belt and the rollerblade wheel the front and back are connected with some small pieces and you can see the shape to which I need to cut them to that's all done on the bandsaw I use my bandsaw tends to help me guide the pieces flew the blade and now you can see how it comes together then it was just a matter of adding glue and clamps unfortunately the job was an entirely flat so I had to flatten it out on my drum sander and then I glued on the back piece to mount this cover I want to use a similar method that is used on this bandsaw here so the bandsaw cover has these little pins that stick out the back and one here and they fit in some holes in the frame so I basically want to do the same here you got some holes he had to because I screwed up and now I gonna put this on and I can find the right hole positions with these dowel Center finders I shape the dowels conical on one end that makes it easier to put a cover on with the cover mounted the machine is pretty much fully enclosed so yeah this cover came out quite nice and it really looks interesting now some of the gaps that were left from the blue up I filled with sawdust and glue and now I can send over all those corners and the best tools Lewis well is a disc sander because everything on the sander came out much better than I expected I decided to really finish it so I sanded everything to 8120 and finally to 180 grit and then I painted and varnished everything in the same green black color scheme that all of my homemade machines follow I put on two coats of paint and one coat of varnish to give it some gloss and I also sealed the edge of the disc and the table with varnish the painting came out pretty nice I think then it was time for it to get to its new location in the shop so the last thing the sander needs is the connection to the dust collection system I have this 90 degree elbow here and this fits my hose and the other end fits into the hole and make a little clamp at the side and this holds in place and here I have a outlet from my pipe system and I can finally put on another one of my homemade blast gates and now I just need to cut the hose to right length and connect the two pieces and now it really is ready to use so being said that the senator started as an experiment it turned out way better than I expected and I really like how the cover came out of course it is inspired by a the bandsaw cover but I think it looks really nice and interesting and this sender will see a lot of use and you will see it in a lot of my future videos but believe it or not this one is just temporary I already started to draw plans for a combination disc and belt sander but I don't know how soon I will get to this maybe two or three months from now maybe longer I don't know but I will get to it and there will be another video series about building it so stay tuned and thanks for watching
