What causes torn grain when using my Jet Planer?
Torn grain when using your Jet Planer can be caused by: * Too heavy a cut: Adjust the depth of cut. * Knives cutting against the grain: Cut along the grain. * Dull knives: Sharpen the knives.
What causes uneven knife marks on Jet Planer?
Uneven knife marks on the workpiece from the Jet Planer are often caused by nicked or misaligned knives. Align the knives and replace any nicked knives or rotate the knife inserts.
How to get rid of fuzzy grain when using my Jet JJP-12 Planer?
To eliminate fuzzy grain when using your Jet Planer, consider the following: * **Wood moisture:** Ensure the wood is properly dried, or use different stock with lower moisture content. * **Knife sharpness:** Sharpen or replace dull knives/inserts.
Why is the finished stock concave on the front end after using my Jet JJP-12?
If the finished stock from your Jet Planer is concave on the front end, it means the outfeed table is higher than the knife. Align the cutterhead knives with the outfeed table.
Why is the finished stock concave on the back end after using my Jet JJP-12 Planer?
If the finished stock from your Jet Planer is concave on the back end, it indicates that the knife is higher than the outfeed table. Align the cutterhead knives with the outfeed table.
Why is the chain jumping on my Jet JJP-12 Planer?
Chain jumping in the Jet Planer can be caused by inadequate tension, misaligned sprockets, or worn sprockets. Adjust the chain tension, align the sprockets, or replace the sprockets.
What causes snipe on Jet JJP-12 and how to prevent it?
Snipe, or unwanted indentations at the beginning or end of a board, can occur on your Jet Planer due to several factors. While it can't be entirely eliminated, you can minimize it by: * **Adjusting table rollers:** Ensure rollers are set to the proper height. * **Supporting long boards:** Use extension rollers to adequately support long boards. * **Adjusting feed roller tension:** Make sure the feed roller pressure is even from front to back. * **Sharpening knives:** Dull knives can contribute to snipe, so keep them sharp. * **Butting lumber properly:** Butt each piece of stock end to end as they pass through the planer.
What causes fuzzy grain when using Jet JJP-12 Planer?
Fuzzy Grain can occur if you are planing wood with high moisture content. Remove the high moisture content from the wood by drying it. It can also occur if you are using dull knives, so sharpen or replace/rotate the knife inserts.
Why is lumber feeding poorly through my Jet Planer?
Poor feeding of lumber in the Jet Planer can be caused by: * Inadequate feed roller pressure. Adjust feed roller tension, and if proper tension cannot be achieved, replace feed rollers. * Planer bed rough or dirty. Clean pitch and residue, and wax the planer table. * Transmission v-belt slipping. Tighten the transmission v-belt. * Surface of feed rollers clogged. Clear pitch and residue out of teeth.
Why is my Jet Planer leaving rough grain?
Rough or raised grain when using the Jet Planer may occur due to: * Dull knives. Sharpen or rotate the knife inserts. * Too heavy a cut. Adjust the depth of cut. * Moisture content too high. Remove high moisture content from the wood by drying.
