Sanding Drum Helpers / Valets de tambours à ponçage

Un tambour à poncer fixé sur une perceuse à colonne est très efficace pour poncer tous calibres de courbes. Souvent toutefois la vis ou le boulon de serrage empêche le tambour d’être en parfait contact avec la table.

A sanding drum chucked in a drill press is very effective to sand any sizes of curves. However sometimes the tightening screw or nut prevents from full contact on the tabletop.

Une solution est de percer un trou dans une chute de contreplaqué, laquelle est fixée sur la table avec des serre-joints. Ainsi le tambour peut être utilisé sur toute l’épaisseur de la pièce à poncer.

A solution is to drill a hole on a plywood scrap, which is secured to the table with two clamps. Therefore, the drum can be used on the full thickness of the workpiece.

Pour aller un peu plus loin, j’insère des cales entre la table et le contreplaqué pour user le tambour sur toute sa largeur, par économie.

To get a step further, I insert shims between the table and the plywood to use the drum along its full width, for economy.

Quelques fois j’ajoute un troisième pièce, tel que montré, qui procure un support complet le long d’une planche pour agir comme un guide de dégauchisseuse ou pour garder la planche droite et/ou éviter les irrégularités. Une fois encore, le manchon à poncer peut être utilisé sur toute sa largeur.

Sometimes I add a third piece, as shown, that provides full support along a board to act as a jointer fence or to keep the board straight and/or to avoid irregularities. Once again, the sanding sleeve can be used along its full width.

J’utilise ce même guide à ma ponceuse à tambour verticale maison. Soit dit en passant, la flèche indique le sens de l’alimentation.

I use the same fence at my homemade spindle sander. By the way, the arrow shows the feed direction.

Tels jeux de tambours et manchons sont très pratiques et peu dispendieux. Voici un exemple.

Such drum and sleeve kits are handy and cheap. Here’s a sample.

Le même guide se marie également à une ponceuse oscillante commerciale.

The same fence fits on a commercial oscillating spindle sander as well.

    I like this. I have done something similar, but made a place to insert the clamp head in the booster shims. That way the clamp head is under the work surface.

    • Good idea, Wally. Many thanks for sharing your find.

      Best,

      PS: Did you try to cut your inner tube racecar tires on the band saw ?

      • Wally Flower says:

        No band saw, but one of our fellow workers has come up with a board marked with lines he follows as he uses a box knife. He does pretty well, but I will try other approaches. Our tissue box is taking up most of our attention now. We’re really proud of it. When I update the website with pictures of the boxes, I’ll write.

        I have a couple pictures of the tissue box on the website if you care to take a look. http://chancefour.sharepoint.com

        The oval medallions are able to be removed and replaced with other designs for holidays or school events as well as school mascot logos.
