Topic tags/keywords: jointer robland 16 parallelogram bed alignment tersa head shims

Hey everyone, I’ve spent more time then I’d like to admit trying to properly align a robland S410. It’s a 16” jointer with a Tersa cutterhead and I’m having one heck of a time trying to do this alignment. I picked up all of the ‘proper’ tools that I could find to help me with this; a 50” Lee valley straight edge (it’s the longest one I could find that is of any quality), multiple sets of feeler gauges, 2 separate dial indicators. I feel like ive tried everything. The thing with the Tersa head is that the knives set themselves so there isn’t any play with that and the bed is a parallelogram bed but there isn’t mechanism to do any adjusting, your supposed to use shims ( at least that’s what I was told). A particular question I have is say you set your straight edge straight across your both of your tables at the far, middle and near end and everything checked out and then you set it on diagonally but now your off is that acceptable or is that telling me that I’m off somehow? So if anyone out there has any experience with this particular machine or just any insight with this that would be very helpful and much appreciated. Thank you

I don’t have experience with it but I was wondering what was going on with it that caused you to want to properly align it? Doesn’t seem too bad by what you are describing.

How well does it joint a board…if that’s good I’d say you have no problems.

Lee Valley straight edge is just not good enough to setup a jointer. You need a precision straight edge.

I have not set up a Robland jointer. Are you sure the tables are out of alignment some times just a rise or fall of the out feed is all that is needed.
Good luck

The Lee Valley straight edge was the best one I could find but I’ll check out that link that you posted. So what is happening when I edge joint 2 boards and put them together I’m getting a small gap on either end or one end if I clamp them together, not much but probably enough to throw things out of whack if I’m doing a table top.

Hmmm, technically true, but realistically nah…the one you linked to is flat to (.0005) 5 ten thousandths of an inch /foot. Lee valley is (.003) 3 thousands / length, so a 50 inch is flat to 7 ten thousandths of an inch (.003/4). larger yes, enough to matter, NOPE.

With what you have done, I think, you should look to technique now. I have a 12 inch Jet with helical inserts and if you are edge jointing the diagonal measurement you are getting shouldn’t matter. Try moving your fence forward and taking smaller cuts. There is a way to spin a board on edge to see if it is convex or concave. Concave won’t spin and convex has a high spot near the middle and will spin. Try that to see if you are reducing the ends the way you should be.

Wood thrower if your getting a gap at the training end of your board your outfeed is low. The same amount of the snipe a few thousands?
I don’t know what Robs numbers mean. I do know that I have both a lee valley and suburban tool inspection tools mentioned. And they are indeed quite different. The aluminum will sag over a hump or dip into a hollow. Giving you a false reading. Unlike a steel precision straight edge.
So put that in your pipe and smoke it Rob. :)

Good luck

I think you got the noodle straight edge, my 50 seem pretty rigid.

Hey guys, good news I believe my problem is solved. The overall length Of my tables end to end (without the extension that bolts onto the infeed) is 7’ so when I attempted this with a 50” straight edge I was just chasing my tail, wasting time and patience, i just couldn’t reference properly and span over enough length. So up until that link was sent to me I really couldn’t find one longer of any good quality and at that point couldn’t wait for the time it would take to ship. I do have another jointer so I took some hard maple a little over 6’ jointed it, checked it To make sure it was straight and used a few of those injunction with each other and got the robland squaring up wood just fine now. I know This isn’t ideal but I can say that I’m pleasantly surprised that this actually worked for me. So for anyone out there that needs a straight reference and doesn’t want to spend $400-500+ on a quality 6’ or longer piece of straight steel just try that, but keep in mind the jointer that your using to straighten up your stock needs to be properly aligned. I know it’s a catch 22 if your trying to align a jointer but in my case I happened to still have my 6” jet still set up . Now Ive only edge jointed some stock and face planed 6” stock and everything is looking great so I’m assuming if I face planned a 12 or 14 board on the robland it will do the same but won’t know until I get there. So thank you everyone who posted and gave me some assistance here. This was my first post and will paying it forward.

Yeah still so far so good. I’ll be squaring up some 10”w 8/4 walnut tomorrow for a large table top and if everything comes out to spec I’ll say I’m in the clear. I’m just still facinated that an 8’ long piece of straight steel can run you over a grand. Now that I know it’s out there I’m sure I’ll be picking one up.

So then what was the problem? What adjustment did you make?
