Delta 37-070 6" bench jointer Parts

Yes. Delta jointers are a solid, proven choice for most home shops, and the Delta 37-070 6-inch bench jointer is typically a good fit for light to moderate jointing when it is tuned correctly and the knives are sharp. Overall results depend more on condition, setup, and cutterhead/knife quality than the logo on the base.

What “good” means for a Delta 37-070 jointer

A jointer is only as good as its alignment and cutting edges. For a 6-inch bench jointer like the Delta 37-070, “good” usually means it can produce straight, square edges and flat faces on shorter stock without chatter.

Key performance checks:

• Infeed and outfeed tables are coplanar (no twist)
• Fence locks square and stays rigid under pressure
• Knives are sharp and set evenly to the outfeed table
• Cutterhead spins smoothly (no rumble or play)
• Depth-of-cut adjustments move smoothly and hold position

Quick buy-or-fix checklist (used or existing tool)

Before you invest time or money, we recommend checking these common wear points:

• Bearings: listen for growling or vibration at speed
• Cutterhead/knife condition: nicks cause ridges and tear-out
• Fence faces: dents or bowing can prevent square edges
• Table surfaces: rust pits and dings can snag stock
• Drive components: belt condition and pulley alignment (if belt-driven)

Typical expectations: bench jointer vs. floor jointer

Feature	6-inch bench jointer (like 37-070)	Larger floor jointer
Best use	Small projects, edge jointing	Frequent use, longer boards
Stock length comfort	Short to medium	Medium to long
Setup sensitivity	Higher	Lower
Upgrade path	Tune, sharpen, dust collection	More power, longer beds

Why it matters

Most “bad jointer” complaints come from dull knives, mis-set knife height, or tables that are out of plane. When those basics are corrected, a Delta jointer can produce clean, repeatable joints and reduce sanding and glue-line gaps.

Finding the right parts and diagrams

For the Delta 37-070, we recommend using the model-based diagrams and parts lookup first; then, if you are searching beyond the model list (for example, hardware or accessories), use Sears PartsDirect to search by model number.

No. On a Delta 37-070 6-inch bench jointer, the jointer’s job is to flatten one face of a board and straighten one edge; a planer’s job is to make the opposite face parallel and bring the board to a consistent thickness.

What each tool is designed to do

• Jointer: creates one flat reference face, then one straight, square edge
• Planer (thickness planer): makes the second face parallel to the first and sets final thickness
• Why they are not interchangeable: a jointer does not control thickness across the full board the way a planer does

Task	Best tool	Result you can count on
Flatten one face	Jointer	Flat reference face
Straighten one edge	Jointer	Edge ready for ripping/gluing
Make faces parallel	Planer	Uniform thickness
Reduce thickness evenly	Planer	Predictable final dimension

The right workflow for flat, consistent boards

We recommend this sequence for most lumber:

• Joint one face until it is flat
• Joint one edge square to that face
• Rip the opposite edge on a table saw (using the jointed edge as the reference)
• Plane the opposite face until the board reaches final thickness

Why it matters

If you try to “plane” with a jointer, you can end up with a board that looks smooth but is still tapered, twisted, or inconsistent in thickness. Using the jointer first gives you a true reference surface; the planer then makes the board uniformly thick.

Yes. Combination jointer/planer machines are common in woodworking; they combine a jointer for flattening and squaring a board face/edge with a planer for bringing the opposite face to a consistent thickness. If you already own a Delta 37-070 6-inch bench jointer, a combo unit is an alternative when you want both functions in one footprint.

What a jointer/planer combo does (and what it does not)

• Jointer mode: flattens one face and squares one edge to that face.
• Planer mode: makes the opposite face parallel and brings stock to final thickness.
• Not a substitute for a table saw: it does not rip boards to width.
• Not a wide planer: many combos have limited width capacity compared to standalone planers.

Quick comparison: combo vs separate machines

Option	Best for	Tradeoffs
Combo jointer/planer	Small shops, one-machine workflow	Changeover time between modes; shared cutterhead setup
Separate jointer + planer	Faster workflow, dedicated setups	More space; typically higher total cost
Delta 37-070 jointer + thickness planer	Keeping your current jointer and adding thicknessing	Two machines to store and maintain

What to check before buying a combo

• Cutting width and depth of cut you need for your typical lumber.
• Changeover design: how quickly it switches between jointing and planing.
• Dust collection port size and whether your shop vac or collector matches.
• Knife or cutterhead style: straight knives vs helical inserts (maintenance and finish quality).
• Electrical requirements: confirm voltage and amperage for your shop circuit.

Why it matters

A jointer and planer solve different problems; using only one usually leaves boards either flat but not uniform thickness, or uniform thickness but still twisted or cupped. A combo unit gives you both capabilities while saving floor and bench space.
