Summary of "How to Make a Picture Frame with Splines - Easy DIY Project"

The video provides a step-by-step guide on making a picture frame with splines, sharing useful tips learned from multiple attempts to avoid common mistakes.

Key Tips and Steps:

Materials & Dimensions:
- Using Walnut wood, about 7 inches wide.
- Frame sides are 1.5 inches wide.
- Designed to hold an 8x10 picture.
- Cut a 1/4 inch rabbet on the inside edge to hold the picture and glass.
- Cut two pieces at 10.5 inches and two at 12.5 inches (final dimensions).
- Start with longer boards (14 inches) for adjustment.
Cutting and Preparing the Wood:
- Use a Jointer jig to clean one edge and reference for Table saw cuts.
- Rip boards down to 1.5 inches wide.
- Use dado blades on the Table saw to cut the 1/4 inch rabbet (since no suitable router bit was available).
- Cut 45-degree miters on each piece with a Miter saw.
- Verify the 45-degree angle with a Speed square rather than relying on saw presets.
- Use a zero-clearance insert on the Miter saw to reduce tear-out and improve accuracy.
- Mark miters to avoid cutting in the wrong direction.
- Check fit with clamps and test the glass fit, widening the rabbet groove if necessary.
Assembly:
- Apply glue and use tape along seams to control squeeze-out.
- After clamping, rub sawdust into glue lines to fill gaps.
- Let glue dry for 24 hours.
Adding Splines:
- Cut splines in the corners to reinforce joints and add decorative contrast.
- Use Maple wood for splines, planed down to just above 1/4 inch thickness for a snug fit.
- Avoid splines that are too loose or tight.
- Clean up splines with a flush trim saw.
Finishing:
- Sand frame with 150 grit, spray water to raise grain, dry, then sand with 220 grit.
- Finish with a mixture of equal parts mineral spirits, polyurethane, and boiled linseed oil.
- Apply a heavy coat, let sit 30 minutes, then wipe off excess.
