Aligning the tables on the 8" jointer

he has a gum welcome back to another video following on from gained and jointer the old jointer refurbished it was time to put it back in their service which means it would have needed a few adjustments better tuning up particularly getting the two bends aligned and once I started doing that I ran into a bit of a problem and that's what this video is about I've got the infeed table back off the joint after having a ball put together because what I was trying to do was just basically fine-tune it and first thing I wanted to do was get the bed's aligned the Infinity outfeed bits aligned with each other but but I came across a major problem when I started doing that and that is that this simply bed is actually walked quite a lot at the cutter head in and I'll try to illustrate that with my rule if I put my rule there now you can see that that's pretty much dead flat as you would want it to be but if we move up to this end via camera then we move up to this end and I put that rule in there as you can see it's high in the middle and down quite a bit on both sides now I don't know what that's caused by because if you have a look at the bed here you can see the original machining marks on the bed so it's not worn out there but they do disappear once you get up here they're not there at all so I'm like the bed's worn out but anyway what I do know is that that has to be fixed somehow and what I ended up doing to fix that your feed table was I actually set it away and had it milled so as you can see there it's been milled perfectly flat absolutely looks like brand-new I was very fortunate to be able to call on my brother to do that for me so a huge thank you to him what I'm going to do now is basically just give it a rub down with some 800 wet and dry and some wd-40 just to smooth off any of those milling marks and then get it back on the machine and we'll fine-tune the machine but the infeed table back on the machine now and basically that's in place and adjusted I've got no shimming at all on the infeed table in that dovetail slider there because some basically because this is the table that's going to be moving up and down I didn't want to put in your shimming in there what I'm going to attempt to do is just have that sitting as it is and the idea will be to adjust the outfeed table to match the infeed table because basically the outfeed table once it's set it's really going to move what i've done to start with I've got you can see that there I've got my outfeed table infeed table aligned there if I run my ruler across here there's a bit of a gap there so that tells me I'm going to need shimming on the front here but before I shim the front I'm going to attempt to align the whole back edge of the outfeed table so what I do is I put a straight edge on that and see see how much it's out down there in D and then I'll put a straight edge on the on the machine you on the infeed table so it's fixed to that infeed table now the strategy I'm using is a piece of 40 mil by 10 mil all I think it's about inch and a half or 3/8 stainless steel square tube so it is fairly fairly accurate and it is the straightest see my having my whole workshop so if we have a look at that now that's sitting nice and flat along that infeed table and it's sitting flat on that front edge of the outfeed table and as I come along you'll see it's starting to get a little bit of a cabinet gonna let in quite a little bit of shimmy down if you can see that down on this bottom corner here the table and we'll see if we can bring that up I've added some shims now to the bottom corner of this outfeed table and all I did was I used um aluminium can strips of alanine you can which works great as a as a shim and that's brought the back edge of the table now perfectly in line with the infeed table so now what I'll do is I'll concentrate on that front edge and bring that up hopefully when I bring the front edge up it won't affect this back edge too much but you'll all just have to see but move my straight edge now on to the front edge of the infeed table so you can see sitting nice and flat there and if I bring it along to here let's see that's that gap I was talking about now just roughly looking at out with my rule it's about one and a half millimeters so I've got to find something that I can put into here that's about one one and a half millimeters and bring that front edge up well I've done all the adjustments on the the two beds now and I've got them pretty much perfect just to run through what I did found these little brackets here the 1 millimeter and they were pretty spot-on actually that one there is sitting in it on its own and that worked out perfectly this one he needed a couple of shims I think I've got to two or three shims mm aluminium can shims and they brought that up perfectly as well so I've got those two shims in there and as I mentioned before a couple of shims on that back lower corner and that's brought for two beds here pretty much perfectly in line so yeah happy with that the process of realigning these bits is is quite fiddly I'll have to admit especially when you've got this type of machine with the just with the dovetail slightest that need to be shimmed rather than having individual camera justice or screw adjusters but there look it's definitely worth taking the time to to get it right it probably took me about half an hour to get this right and yeah that's a good time investment because once it's done it's going to start it's going to start at the quite a while I've got the fence back on the machine now and that's been set back to 90 degrees so that's that so that leaves the last thing to do now on the machine is to set the knives either cutting knives and they're going to be set to the outfeed table now the method that are you going to use to do that is the magnetic jig method with these homemade magnetic jigs there is a really excellent video by Brian Brella from garage wood works who shows how to make these jigs and use them I'll post the link to that video down the down below it's no use me going over that again when like I said and go and watch that video it is quite good so the basic idea behind using these magnetic jigs is what if I found the top dead center you line that up directly with the tip the blade and then this second one here that mark there aligns directly at the center of the magnets underneath so I line that mark up with the center of the blade as well and I've listened off the clamping screw so now that so now what happens is that magnet draws the blade up to the underside of these blocks which put it in perfect alignment with the outfeed tables they just show you they're pushing see that blades loose and the magnets drawing it up so all there now is retighten the clamping screws and I'll do that for um the other two blades the knives have been set in the guards back in place do is give it a try well thanks for watching along I hope you found the video interesting and maybe even got something over that you can use yourself anyway if you liked it give it a thumbs up please feel free to share it along with in my other videos also don't forget to check out Brian grillers video on how to set up the jointer knives and make those homemade made mini geez if you haven't done so already please
