Fellow Report post Posted June 1, 2010 Hi all, FD has mentioned in a thread "Spiral bushing" and he likes it a lot. What is it? How it can be done ? Just want to know. I thought bushing is bushing. Thank you in advance. Quote Share this post Link to post Share on other sites
Brad Dorsey Report post Posted June 1, 2010 A spiral bushing is a bushing made by wrapping some thin material, usually a wood shaving, around a tapered form (in a spiral) then gluing it in the peg hole. Quote Share this post Link to post Share on other sites

cheapjack Report post Posted June 2, 2010 It's a nasty mess to install, maybe somebody has a good proceedure that doesn't slop glue around so much. Quote Share this post Link to post Share on other sites
Fellow Report post Posted June 2, 2010 Do you know the kind of damage that you could do with a plane? ++++++++++++ I thought you were talking " airplane" sometime we it plane . A plane (tool) can only make a flat surface, right? A flat surface is not what we want in making violin. Quote Share this post Link to post Share on other sites
arglebargle Report post Posted June 2, 2010 Yuen, this is a simple procedure. You can easily do it with your hammer, screwdriver, dulled cutting instrument, tape measure, thumb tacks, balled up twine, sorghum glue, fish paste, fence jack, tattoo ink caddy, mitre box cozy, left-handed bacon stretcher, and pencil. GO FOR IT! :) B) Quote Share this post Link to post Share on other sites
iburkard Report post Posted June 2, 2010 ++++++++++++A plane (tool) can only make a flat surface, right? A flat surface is not what we want in making violin. There are rounded thumb planes and gouges for scooping out wood. There are also many flat surfaces on a violin (almost every glued area), so a flat plane is useful. You should buy a real plane though... erh. Quote Share this post Link to post Share on other sites

If you cannot do a good spiral bushng job, rather not to do it at all. Quote Share this post Link to post Share on other sites

Oded Kishony Report post Posted June 2, 2010 I make spiral bushing from kraft, mulberry or other reinforced paper or tyvek in the fixture pictured below, then install them as I would any bushing. The fixture is made of Delrin The holes made with my reamer The plugs shaped on my peg shaver. The dark object is a completed bushing ready to install Oded Quote Share this post Link to post Share on other sites

catnip Report post Posted June 3, 2010 Oded's method looks very good, though I've never tried it. I use something similar to Oded's method. I find that kraft paper spiral bushings end up being quite visible as the paper darkens when it absorbs the touch-up varnish. A prefer plain maple shavings which I collect from woodshows from people demonstrating Lee Valley planes. I use a waxed fiberglass or wooden tapered rod as my bushing template trimmed by my peg shaver. I layout about a 2" maple shaving, a small piece of wax paper and a piece of scotch tape - sticky side up. I brush the maple shaving with diluted yellow carpenter's glue ... (like glazing an egg roll) Roll the shaving around the tapered rod. Then roll the wax paper around the shaving Then roll the tape around the wax paper. Gently twist the bushing off the tapered rod and set it aside to dry then repeat .. I usually make about 20 at a time of different diameters sizes .. it all depends where you start rolling the shaving. These bushings are only about 3 or 4 turns thick and virtually invisible especially if you slightly ream the bushing after. Quote Share this post Link to post Share on other sites

Brad Dorsey Report post Posted June 3, 2010 I use something similar to Oded's method.... Do use any type of outside form the way Oded does? If not, are there any tricks for winding your shavings tightly on the mandrel? Quote Share this post Link to post Share on other sites

The dark object is a completed bushing ready to install I do them almost exactly the same way, right down to the Delrin mandrels. I'll glue them in place while they are still flexible, and keep compression on them with the mandrel - I have several, so doing a whole pegbox in one sitting is easy. I usually use Kraft paper, and I like to work next to a sink so I can keep rinsing the glue my fingers. I just keep rolling them until they are tight. They seem a lot better reinforcement for a weak peg box than end-grain bushings, and IME, they are faster and easier. Always, when I do touch-up, I seal the surface first, so the bushings don't absorb color. They are very thin and virtually disappear with minimal touch-up.

Oded Kishony Report post Posted June 3, 2010 Currently I'm using archival Tyvek which comes in two thicknesses. It's very compatible with hide glue which I prefer. ~OK Oded,Are you using Tyvek envelope material? Quote Share this post Link to post Share on other sites
propolis Report post Posted June 8, 2010 Whew. Just got done warming up the sole of the jack plane on a piece of neck block offcut, and there is a basket of shavings waiting. Question: I have used yellow Titebond on brown paper, and hot hide glue for maple curls and boxwood end grain. Is there any reason to change the choice of glue there? This time it will only be the large holes, since I am converting an older one to modern taper, if that matters. Quote Share this post Link to post Share on other sites
