Pack of 5 O Rings In expensive and indispensible - a slight interference fit between the dummy launcher and the O ring at the end of the dummy launcher spigot is essential if the dummy is to achieve distance when the dummy launcher is fired

Bull  Nose Center by jjr2001 -- Here is a rather large (for me) bull nose ball bearing center. It is 3" in diameter with a Morse Taper 2 shank. The MT2 is machined out of one piece of steel along with the bearing hub. I should have taken some pics of that part prior to assembly to show how the bearing is retained. I will try to explain it: First off the inner race of the bearing is an interference fit to the shaft. I froze the shaft and warmed the bearing (no grease yet). It is a good…

Here's a simple frame modification I came up with that allows a standard Hoffman frame (British National deep, 35 mm spacing) to be used in a KTBH.  Fits the 'standard' KTBH dimensions as given on the BB site, leaving an 8 mm B/S on either side. Serendipity.  Bottom bars can be removed by simply pulling out a couple of interference-fit panel-pins, if desired.

Lens Holder by mklotz -- I had a high-quality lens rescued from a piece of militaria and decided to make a stand for it.  A piece of clear plastic tube had a recess cut into it to accept the lens and hold it exactly at the lens focal length above whatever the tube was placed upon.  Another piece of tube was reduced in diameter to be a interference fit in this recess.  It serves to hold the lens in place without the need for any glue.  On the top of this latter piece a circle of 0.010"…
