Has anyone had ANY problems with the actual performance of the A3 31 jointer/planer?
- Extension tables--Do you use them? What size do you use? Where do you use them? If using large table extension on the jointer infeed or outfeed, do you have any problems with alignment when you apply pressure necessary for jointing? Any problems with accuracy (snipe?) when using the extension tables? If you are getting by with long pieces without using extension tables how and is the accuracy acceptable(snipe?)
- Switching back and forth between jointer/planer--Do you find any hindrances to your workflow having to switch back and forth? (I know sometimes I joint and plane and then realize I don't have enough wood and have to go back and form up some new wood...how easy is it to reproduce the settings? Any workarounds for those hindrances?
Dust collection--What dust collector do you use with it? Does it provide effective dust collection?
Mobility--What specific mobility do you have on it (Zambus or stock Felder)? Does it work for you or are there any issues?
Quality/performance/ease of use--How are you getting along with the quality? Does the eurostyle guard work for you? Any snipe?
Performance has been everything I expected (excellent) and more. What I expected was to have a machine that was built with quality, precision repeatability in mind. Once you have the machine dialed in, it just simply works (and does it extremely well), and that is the biggest selling point for me. My prior jointer was inexpensive and required re-dialing in and extensive setup, and it was jury-rigged for co-planar. It was not a joy to use. The A3-31 jointer table came dead flat and coplanar and opens and closes back to dead-on...over and over. The fence remains at 90 degrees vertical (i check each time i edge joint). The planer height micro-dial is spot on. The materials used and the level of fit, finish, precision are superior to the Taiwan made machines I looked at.
I don't use the extension tables. Haven't needed them yet. Most stock i run through is less than 2 feet long. I will need to run longer stock next year for a large project. I may get the extensions then.
Switching between J and P is (for me) a 10 second operation. I plan my workflow so that I face and edge joint a lot of wood, then switch to the planer. Repeatability is astounding. I can reproduce a prior setting to a tenth of a mm because I have the digital handwheel to set the planer table. I HIGHLY recommend that feature. Yes, at times I need to go back and forth between the J and P mode, but it isn't a deal breaker.
I have a Penn State Industries 3.5HP Tempest cyclone dust collector. It works great. Not every single chip is collected in planer mode, there is a small handful that wind up on the planer bed. Not an issue.
I have the Felder mobility kit, there are no issues for me because 99% of the time I am just moving the machine forward and backward, so the felder kit works perfect for me.
Quality and performance for me (hobby woodworker) are fantastic. Looking back at the extra money the Hammer cost vs a Jet or Grizzly JP, I am extremely happy with the trade off, I would buy the machine again, and I highly recommend it if the budget works. No knocks on Jet or Grizzly, they make good machines.
I really like the euro style jointer guard. I prefer it to the pork chop swing away style.
I had some snipe when I first got the machine. Adjusted the rollers and now have virtually none.
p.s. I have the silent power cutterblock and I really like how it handles figured woods. it's not tear-out free, but it reduces tear-out vs my old jointer and planer (ridgid jointer, dewalt planer) by probably 95%. I still get some, but it's so much less of an issue now.
here is the current set up, you can see the Hammer JP and the dust collection.
All of the above is just my opinion, i'm not a professional woodworker, just a hobby guy. What I write is just based on my experience and I try to give my forthright thoughts and opinions without unwarranted or undeserved hype/praise.
Best of luck with your decision.
