Update to the update - The spacers will be cut from 316 stainless steel, not 4130 as previously stated. The price is the same.

I have received quotes from machine shops across the country. The best I have received would result in a price of $1.50 per spacer including sales tax and shipping to me.

FYI there are 37 of these bearings in a Jungmann, so 74 spacers would be needed for the entire aircraft. I would guess a Jungmeister is about the same.

One of the current challenges for Bucker owners is sourcing the 19mm self aligning bearings found throughout the control system. These are unusual in that the outer race is 6mm thick, but the inner race is 14mm. Here is one solution.



The bearing is a 19mm dual row, self aligning bearing part number 126TN. These are made by a number of suppliers and the best price I have found is here: http://www.vxb.com/page/bearings/PROD/Self-aligning/Kit7039   $4.95 each.

The spacers are cut from standard 4130 seamless tubing of OD 3/8", wall thickness 0.65" (Aircraft Spruce 03-01500) and are cut to exactly 4mm long. Two spacers (one eiher side) will provide a bearing indistinguishable from the 6/14mm originals.

I called a local machine shop to see if they could cut the spacers for me. I got lucky because they turned out to be "precision grinding" specialists and that it turns out, is the prefered technique for producing spacers. The cost for cutting 100 spacers was very reasonable.
