I drew up a print for the extension. A friend made the wood pattern for free. A retired foundry owner cast 5 extensions for $7.00 per pound. A tenant of mine faced off and bored the aluminum castings for free. After that, NO MILL NEEDED needed. I hole sawed the Ford banjo. Holes only had to be close as long as the lower shaft did not hit. I made a fixture off of a Halibrand to install the front bearing retainer. *** Eliminating the need for a tube running through the case. My design ***ELIMINATED the heavy 7/8" thick plate [ Frankland, Bart , Highlend and several others ] and all the welding. *** ELIMINATED the 1/4 plate to hold the spacer ring in. *** ELIMINATED the spacer ring. K I S. Bottom of the picture is the template for flame cutting the small 3/8" thick lower extension for the rear. You see it in one of the Q C pictures. I have 3 in my hot rods. Sold the other 2.
Sorry. No other pictures. I sold everything in picture for $500.00 years ago. The buyer is in way over his head. Has yet to make a Q C.
What holes are you talking about? If you mean the front and rear holes for the lower shaft to pass through. I just took a guess. I used a hole saw by hand. The 2 short tubes are welded to the outside of the case so the 2 holes don't even have to be close. Just clear the shaft. More K I S.
Every hole in the whole housing needs to be square with the world. Did your jigs have a straight seat/base to place the work at right angles to the drill and cutter?
Let’s bump this again so everyone can see you calling me a dog. FYI, I have a little experience in building a quickchange, and we made sure every surface was true and square with extensive fixturing.
It's been along time since I built one of these Q C's. The only time I needed a drill press was for the 6 cover bolt holes in the cast aluminum extension and the front seal plate prior to welding it in place.
