Tips for Turning and Finishing Floral Blanks
Floral blanks are different from standard resin or acrylic blanks. Because they contain embedded organic materials and layered elements, a slightly different approach during turning and finishing will help achieve the best possible result.
1. Use the Highest Stable Speed Possible with Sharp Tools
Floral blanks generally cut best at higher spindle speeds with extremely sharp tooling.
Recommended Approach
- Run the lathe at the highest speed your setup can safely and comfortably handle.
- Use freshly sharpened tools whenever possible.
- Light, controlled cuts produce the cleanest finish.
- Avoid aggressive material removal near embedded flowers or delicate inclusions.
- Single-point threading is generally gentler on floral blanks and helps reduce the chance of chip-out.
- If using taps and dies, work slowly and carefully, as embedded flowers and organic material can occasionally cause chip-outs during threading.
2. Avoid Wet Sanding When Possible
Wet sanding can sometimes introduce moisture into exposed organic material or microscopic voids around inclusions. Dry sanding is generally preferred for floral blanks.
Recommended Sanding Process
- Dry sand using:
- Abranet 400
- Abranet 600
- After 600 grit, move directly into your finish whenever possible.
Surface Prep Before Finishing
Before applying your finish:
- Use compressed air to thoroughly blow off all sanding dust.
- Lightly clean the surface with denatured alcohol using a blue shop towel.
This helps remove any remaining dust, oils, or residue and promotes better adhesion and clarity in the final CA finish.
3. CA Finish is Ideal
CA (cyanoacrylate) finishing tends to produce the best clarity, depth, and protection for floral blanks.
Recommended Products
A combination of:
- Mercury Thin
- Mercury Medium Flex
works exceptionally well.
Suggested Method
- Begin with thin CA to seal and stabilize the surface.
- Build additional layers with medium flex for durability and depth.
- Apply light, even coats.
- Allow proper curing between applications.
- Polish carefully after final cure.
4. Final Sanding and Polishing
Once the CA finish has been fully applied and cured:
- Gently sand with Abranet 400 to smooth out any ridges or unevenness in the finish.
- From there, lightly sand and polish using your normal finishing routine for resin blanks.
Keep in mind that CA is significantly softer than resin and can sand through very quickly. Use minimal pressure and only sand as much as necessary to level the surface.
If buffing:
- Start with your polishing compounds rather than aggressive cutting compounds.
- Compounds labeled as “cut” (such as medium cut or heavy cut) can remove material very quickly and may burn through the CA finish unexpectedly.
A lighter touch during the final polishing stages will help preserve clarity and maintain a deep, glass-like finish.
