1915 Militaire build
Hey Militaire fans we have another one of our weekly updates on our 1915 Militaries progress. This week JaDon and I were in the school’s CNC machine shop to mill the bearing housing to make sure our saddles fit properly. First we had to tram the head of the mill to make sure it was level on the Bridgeport table. We then used an interapid indicator on our motor case to make sure the case was even and not twisted during the welding that took place. Once we had checked out the case (and breathed a big sigh of relief no twist found) we securely fastened the case to the table. We then indicated in the motor to the table of the mill. JaDon and I then carefully used the Bridgeport to mill down the housings and bearings one at a time. Once the bearings and housings were milled downed to the same height we removed the bearings from the housings. With the bearings out of the housings we took off an additional .0005" from the case to achieve a slight crush factor between the bearings. We have
new studs for our case and we are getting very close to floating our crankshaft.
We also need to hone the bushings of the camshaft because we need a .004" clearance between the shaft and bushing. We found a tight clearance of .001" between the bushings and the camshaft. This weekend I will be at Mr. Hill’s shop working with a Berco B-T6 hydropneumatic line boring machine. We are still waiting on our crankshafts that are expected to be here tomorrow, so until next week enjoy our photos and this update on our great 1915 Militaire!
