Newby - Jointer Blades knives source?

[wwbbq]

Thanks in advance to all you dedicated folks who shepherd along us beginners!!! My first post, although I've been peeking for years!

I was given a 10ER (53490) w/speed changer!, by my father-in-law a number of years ago - who has since passed. I finally found the jointer in his basement when cleaning out, and now in the process of restoring. It is a Magna 4E (4 inch - serial 4015), in good shape, considering all the layers of stuff it was under. But, the blades need some help. I was able to remove them (with some help from the SS Forum) and currently getting rehabbed/sharpened by local commercial sharpening company, who I have used to sharpen items before.
I've search the SS Forum, but my head is sort of spinning - since some of the source info is out of date. I would like to get a new/backup set of blades (knives) - are the ones sold on the SS site correct for my older jointer? Mine has 3 screw hold down wedges. The blades that were in it are marked "Disston" and obviously not OEM. The blades currently in it are 4 x 3/4 x 1/8. Are there other blade sources?

BTW - It's predominant use for along time was my son turning Duck Calls, out of exotics. Now he's 30 - has his own lathe, and I can use it again!

Many thanks to all your Jedi's !!!

Disston knives are likely OEM SS. The wedges do not affect the knives(IIUC).

Anyone know differently?

Disston supplied Magna with several items for the Shopsmith tools. Not only the Jointer Knives but the Lathe Chisels too. Now the good news - Your Model 4E Jointer is the predecessor to the current Shopsmith 4" Jointer. When the Model 620 4" Jointer was made for the Mark 5 in 1954 it was primarily the Model 4E with a change in the out feed/base casting adding the mounting posts. There have been a number of changes since then but anything except the out feed/base for your Model 4E can be replaced with current parts including the blades. Do note that some parts must be replaced as assemblies while others can be replaced individually. All the upgrades made to the Jointer with the exception of the Dust Chute can be added to the Model 4E. I have a Model 4E jointer and it works just a well as my 1979 Jointer with upgraded dust chute, feather board, blade and safety guards. Although using the 4E is a lot messier not having dust collection.

Well, that is all great news. Thanks to you all for the information - this is a real help. I hear ya on the dust collection! I had a 6 inch freestanding (another brand) and dust collection was a nice feature. But I donated to a buddy to save some space. Now all I need to do is find another mounting kit. Family lore has it that the 10ER fell off the back of a pickup truck, and was damaged, at some point when they moved. I finally dug in, and found that the cast vertical arms that support the planer from the mount were broken off. Someone made replacements with adjustment slots out of mild steel , albeit a nice attempt, and bolted them to the mount. It's OK, but not great. Thanks so much for the info!

The Hinge Plate part number C 2719 that attaches between the jointer and the special Jointer Headrest does come up for sale rarely so you need to keep an eye out for one. It appears that the "ears" where the plate bolts to the jointer is the common spot they get broken. As for dust collection I now have a positional flex hose I plan to try next time I use the 4E jointer. It is Shopsmith P/N 556186 Stay-Put Dust Collection System. I believe it will work better than nothing and I can get it pretty close without touching the cutter head.

If you have not seen it elsewhere this is how the Model 4E Jointer looks mounted to the Model 10ER Shopsmith not including the belt to the Jointer.
