Carbide is offered by Tersa and those who use them feel they are worth the heavy price.? I think Joe Calhoon runs two carbide with two blanks and feels the two knife head gives him the best compromise.? Two knife heads used to be common on euro machines with
large diameter heads running at 5000-6000 rpm.? The attack angle and tip speed were such that the finish was supposedly very good.? My Bauerle is in transit and has a two knife head so I will have some experience in the future.? Dave

?I believe all the hammer j/p¡¯s are the same build, ad941 is where the 4 post planer table begins, it is spring assist not too bad of a lift. I don¡¯t think I would not get a 16¡± just because you heard it was harder to adjust, like Brian said
once its set it pretty much sticks unless a big move then maybe a readjust is in order.
Helical has been great, couldn¡¯t imagine going back to straight knife on a j/p combo, if separates then helical on planer, tersa on jointer. If I had a wide belt and separates then maybe tersa on planer as well. Wouldn¡¯t worry about the time spent turning
the carbides on the helical, you won¡¯t be doing it that often.?
I had a 12¡± mm j/p for 30 years in addition to my scm 63b, glad I went to the 16¡± AND power drive, power drive has the ability to change your life! Of course you would need to jump to the ad741...

D Kilen,
This is going to be a generic response but you may find some information useful.
I am not sure if more problems reported on 41 (if that is true) necessarily means that it has more problems. It could be due to the fact that there are many more 41s sold compared to 31.
I have dual51 so cannot give you direct feed but in general the higher model usually has improvement in design, not sure if this is applicable here. This improved design could mean that 41 is more adjustable or easier to adjust. I would look
into this.
One criticism of 41 (i think it was AD941 but not certain and not sure if it is still true with latest model) was the lack of spring assist in lifting the tables. I am 5¡¯8¡± 60 yrs of age and 160# and I have no difficulty in lifting dual51 tables.
This is something that a user does a lot so perhaps you can look into that.
Another major diff could be that 31 planer table has a single post vs 4 posts on 41. That is big on my list.
I would recommend checking both machines out. If you are not near a showroom check them out by locating a 31 & a 41 owner near you. Many of us here are perfectly willing to show machines, granted we have to be careful due to covid.
Good luck,
Imran

?Stan,
good info and thanks!? It seems there is a trend with the bigger beds on the 41 it is trickier to get them co-planer.? I have heard from several people that the 12" is a piece of cake but even though they love the capacity of the 41 some have had problems and
maybe even had to pay to have a tech come in.? I would love to hear some details from owners of both sizes.? thanks again
