Topic tags/keywords: planer plane

My brother are building his bench. Using SYP. Home Depot stuff. Premium boards but very wet and very resinous. We cut the wood for the top and jointed two sides to square on my 8 inch jointer. No problem. We go to my relatively new Oliver 16 inch/ 5 HP planer and the machine is getting “bogged down” and the wood is being grabbed by the helical head and not advancing?? We ran thru a dry piece of SYP, it advances easily. No problem. Could the very high resin and water content be responsible? We have 17 -18 pieces of wood left to plane and I really do not want to hand plane the 3rd side to flat.

Thx
Chris

Do you have a moisture meter? What I normally do at the big box stores is sift through boards, lift them and feel for discrepencies in weight. Sometimes its pretty dramatic between the inside of the stacks and the outside.

How thick of a cut are you taking?

Do not have MM. never had an issue with planer getting bogged down before.

Trying to take 1/16. Right under the middle “guard”. The New Oliver planers are basically the same planet as the Powermatic.

interesting. First if it’s that wet then stop, it needs to dry more. typically unless you bought pressure treated it’s not that wet though. it’s possible the feed rollers are just not grabbing it, but it’s also possible the cutters are getting filled with pitch and not cutting. I have not tried an insert cutterhead and worry about resin for this reason (I use a lot of pine)

That’s really wet maybe too wet for making a bench.
Don’t forget clean out your inserts after your done with that fat wood. It’s a bear to clean out the pitch when it mixes with other wood dust and oils.
This is another reason I don’t like Bryd heads they do a poor job on the most ordinary soft woods.
Sounds like good fun building something with your brother.
Good Luck

Couple of things:

1) Make sure the planer table/bed is waxed, and slippery. Want minimal friction across the table.

2) Try adjusting the height of the rollers inside the lower cast iron table.
For smooth lumber, I set these to 0.0 to 0.001” above the table and works fine. But for rough lumber, using a height of 0.003-0.005 above the table will result in more consistent pressure against the in-feed/out-feed rollers and more consistent feed rate. BTW – Using a lower height for smooth lumber helps to reduce the marking from the serrated in-feed roller on light cuts.

3) Since it’s a new tool, double check all your height settings, and spring pressure on the in-feed roller.
IMHO – With a decent 1/16 cut: If you have a serrated in-feed roller and wood is getting stopped at cutter head; either the roller/cutter relative heights are not accurately set, or not enough spring pressure on in-feed rollers?

PS – I just punched up the manual for Oliver 4220 16” planer:
http://www.olivermachinery.net/uploads/4420-manual.pdf

One thing I notice that is ‘different’ in these instructions from most other 15” 4 post planers I have worked on:
The relative head heights are unusual?
Most 15” planers (Delta, Powermatic, Grizzly) call for in-feed roller to be ~0.040” below cutter head, and the out-feed to be 0.020”. Oliver suggests 0.02” for both?
IMHO – 0.040” is too much, as it makes it harder to push wood into the planer. I set my in-feed to 0.028-0.030” below my cutter, and out-feed to 0.020”.
Using a ~0.03” height for in-feed, the only time I see feeding issues is with very rough lumber. And that is why I use higher bed roller for rough lumber. The bed rollers are much quicker to adjust with cam screws, than the feed rollers.
So I’m also suggesting that using 0.03” in-feed height might help. :)

If you don’t have the proper tool for the adjusting job, this might help:

PS – If the wood is too wet, you will spend a lot of time cleaning pitch off the rollers, and cutter head. Suggest you avoid wet resinous wood, as cleaning a shellix head is zero fun.

Best Luck!

Hope this helps.

Thx all. I rose early this AM and did peruse the manual. I made some slight adjustment in the roller spring tension. Bottom line: operator error. I was late, I was tired (bad to work with power tools!) and missed something obvious. I was running the board a bit to close to the feed height guide. The board would take a slight jerk as it started the planning and then catch on the height guard.. I took more care in my height adjustment and just planed about 18 boards with no issues. Lesson: when you are tired, just pack it in. There is always tomorrow. After a good night’s sleep, the world is a different place!!!

Do a light initial milling, cut to length then you need to sticker the lumber for at least 1-2 months to acclimate.

Typical construction lumber can be up to 20% moisture, which will lead to problems if you build the bench with wood in that condition.
