Topic tags/keywords: jointer planer combo mortiser

Hi everyone! I’m a new poster here, but I’ve read a lot of posts over the years. I’m hoping to get an idea of the value of a tool I can’t find online. I’ve stumbled on a Knapp AD410 Profit jointer/planer combo, distributed by Laguna, when my friend’s father died. He has a whole woodshop full of amazing tools, all of which I know what they are worth, except for this one. I can’t get a comparable value anywhere. Does anyone here know what this thing is worth on the used market? I believe it is 16” and it has the mortiser. It has straight knives.

Would I be an idiot to let this slip through my fingers? What is a fair price to either ask for it or offer for it?

I’d appreciate any help you all can give me!

I gave $1750 for mine I think, a couple of years ago. Without the mortiser.

It’s 6hp 3 phase so you’ll need to plan for that.

Thanks, Loren. That’s super helpful.

That’ s a lot of power…gulp. I don’t have 3 phase so I’ll have to work that out. Does yours have a spiral cutterhead or straight knives? Are you happy with it? Would you recommend that I buy it for myself or sell it for them?

I currently have a Grizzly 8” parallelogram jointer with a spiral cutter and the Dewalt 735, also with a shelix cutterhead. I’d love a bigger machine and I’d love to save the space and have just one, but I don’t want to bite off more than I can chew with machinery.

It has straight knives. It’s a great insert system but knives are more dear than the more common Tersa knives.

It’s a helluva machine. Welded underwater to prevent distortion. Knapp made stuff so good it drove them out of business. You don’t need a 16” jointer for most work. Your equipment is fine. You’ll love the mortiser but most guys today want a domino so that makes it a wash for a lot of work if you figure on using a domino anyway, minus the $1000+ price of the domino . If they take an offer of $200 or whatever you could sell the gear you have at near enough to that the machine will feel like a screaming deal.

I fear the circumstances of the company being defunct and the 3 phase power will inhibit my resale value but it can’t be by too much. Guys pay $7000 for a comparable Minimax model with no qualms.

Mine has an extension table too. The feed runs on a variable speed drive with a separate motor. The machine is built like a tank out of 5mm steel but if the internals break I’m out of luck. I hope they built it to last.

I use a 10hp rotary phase converter. It wasn’t too pricey to build with a motor I found locally on ebay. 3 phase motors don’t keep much value on the secondhand market. The converter box and wiring were about $350 I think. You’ll probably need a 100 amp panel in your shop. You can get passive phase converters (I forget the terms) pretty cheap and they reduce power by 1/3rd. 4hp would still be adequate imo.

Hi Loren, thank you so much for the advice and input! I went back and saw that it is running perfectly and it is already set up for single phase 220 and he had it set up on a 30amp circuit. Crazy. If I need more power I can run it because I don’t have to worry about the 3 phase. So, I bought it for $2000 and I plan to sell my jointer and planer. I’m pretty stoked and it’s definitely the most beastly machine in my shop…by FAR.

I don’t have the extension table…but I would buy one if I ever saw it out there. If anyone has one, please let me know!

Where do you buy your knives? Have you considered upgrading to the shelix head?

I just shop around when I need them. I have thought about replacing it but it would be about $1500 and really the head it has is pretty slick.

Shelix heads are all the rage on the interweb and YouTube , but the reality is there are few instances where they make fisical sense.

Now, if your a collector…........they’re priceless.

@Loren – I was able to sell my jointer/planer for about what I bought the Knapp for. It worked out well. I also found the cast iron extension and steel extensions when I picked it up. It’s up and running and rock solid. I do have one question – I am trying to figure out how the back bracket/guard for the fence attaches. I think I’m missing a little “down holder” piece, but the manual is unclear. Is it too much to ask for you to send me a picture of how it attaches to the the main body of the machine? It has a funny little spring plate underneath it that makes little sense to me…

Thanks, again, for your help!

I just picked up a Knapp profi T too really excited about getting it going. Could you please send me the information on planer blades it has a 4 knife cutter head, does it use the Tersa blades? Thanks Mike. It came with a decent manual I can make copies if anyone needs one. Mike

Congrats, Mike! Looks like you and I are in the same boat! I also have a good manual, which has been super helpful. Mine is missing the bracket that holds the jointer fence support contraption down on the back. If you have that and can share a pic of what it is supposed to be, I’d be super grateful!

My cutterhead is a Wigo head. Is that what your’s is too? I haven’t found knives for it online yet…and it looks like it takes very specific ones because I believe they self register.

I have a wigo too, after some research they can be found fairly easily look for centrofix style knives. as far as the hold down mine seems to be absent as well.

Thanks! Yeah, that’s exactly what I have, which has no part to hold it to the main body of the machine. I used a bolt and a large washer and it works well enough for now, but I’d love to know what it actually looked like so I can try to replicate it.

Thanks for the tip about the Centrofix knives.

Someday, once I recover from the purchase, I might upgrade to a helical head. We’ll see. :)

I assumed it slots into the channel on the fence. I never used it so I could be wrong.
