Great addition for bench top jointers

I have a Cutech 8” bench top jointer, and while it’s a great addition to my garage workshop the size of the beds is limiting. It has extension arms which are OK, but not very precise.  I came across this video on YouTube which addresses that problem with extension wings, so I thought I would share it: https://youtu.be/yMhNognmsQU?si=Dc24fYN5-GppKcB-

In summary, each extension wing has a groove routed with a bull nose bit to fit each rail on the arms. What makes this process different from any I have seen is the use of shims to precisely match the extension wings to the jointer bed. I started taking very light passes on the router table, measuring the clearance each time with a set of calipers and adding layers of tape or playing cards where needed until the wing was coplanar with the bed. Then I routed to the depth needed to make the wing flush with the jointer bed. The results are wings that very precisely match the jointer beds.

great addition FD !

working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.

I’ll have to try this. I have the same planer in the small shop.
Thanks for the tip!
Thanks for posting.  I saw this idea a bit ago (not sure if the same source or not) but didn't save the link.  This is definitely on my list of shop projects.  

How do you like your Cutech?

Great addition dog.

Did you use tape of cards to sneak up on the routing... have an ace up your sleeve?... just gagging.

If your first cut is too short... Take the second cut from the longer end... LBD

Great idea!

BB1, I love this jointer, no regrets in purchasing it. It’s much quicker and easier than my old process using a planer sled, particularly for twisted boards. This is the first jointer I have owned, and there is a learning curve to get perfect results. If I want a straight edge on a longer piece of stock I still use a simple jig for my table saw. 

Duck, you always quack me up. I was feeling a bit daffy trying to figure out how to make this work, but I stuck to it to get a cohesive result.


FD,

That is a great idea.  Sure beat doing a jointer job with a thickness planer.

That is a good idea to extend the tables. In the video he said he did this to keep the board from dropping down off the support with the way it came from the factory. He could avoid that by starting with the convex side of the boards down and it will just get straighter with each cut and no drop off. We have to do that with our old Craftsman jointer and it works just fine.

Nice fix Photo Dog. Did you mean a bowl or tray router bit? Not a bullnose bit. They are opposite bits.

Well, maybe I misspoke. What I used was a round nose bit, which I thought was the same as a bull nose bit. Here’s what I got:

Yup. I didn’t know some manufacturers called them bullnose bits. It’s a “bit” confusing. Especially if you order the wrong bit by mistake.

Nice fix, but the best part is you say you like the jointer. I've been looking t these for a while, but haven't pulled the trigger.
