How much interference do you have? If just a few thousandths, you can take that off the axle with emery cloth fairly easier. Much easier to accurately reduce the axle's diameter that to increase the bushing's diameter.

I just looked at Mcmaster's catalog, and the sell oil-impregnated bronze bearings "For 1-1/2" shaft" and a bunch of other sizes. These will slip-fit onto all the designated sized shafts easily.

I've seen some that have a set of gripper teeth below the flat vice jaw faces, and those teeth are designed to grip round stock like rod or pipe. My little vise doesn't have those teeth so I usually use the Armstrong technique when clamping round stock in my vise, unless it's thinwall material or has smooth-finished surfaces that must be protected. In those cases, I just have to use whatever is at hand to keep the jaw faces from direct contact with the work, and that usually means working gently or living with some rocking or rolling of the work in the vise. In the case of an axle like this, would you put some thin leather in the vise jaws to grip the axle, or do you have any nifty tricks for holding round stock securely in the jaws? -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=482552#482552 ________________________________ Message 6 _____________________________________ Time: 07:54:21 PM PST US From: "Clif Dawson" Subject: Re: Pietenpol-List: Re: Bronze-Brass Bearings Sorry, no nifty tricks but the axle doesn't have to be horizontal. With the axle verticle and tight against the body of the vice under the jaws it won't move. I use a couple of things. One is scrap aluminum angle on the jaws, the other is some sheet aluminum clamped then bent over the jaws, top and sides. Leather is fine. You could wrap it around the axle and zapstrap it. Anyone with those pipe jaws--they will dig into the pipe weakening it.

And I know I'm getting way off-topic here, but seeing the nice wood cabane struts and other details on your airplane, in Canada how does your CAA (or Transport Authority, or whoever it is that deals with experimentals) look upon deviations from the plans? In some other countries, every single little thing has to get approval or it won't fly, literally. How much leeway do you have? -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=482564#482564 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
