3" Burrell Eccentric straps and Oilers Year (5)! Happy New Year !! - Well its been a while since my last post and with the festivities over attention can be turned to the progress since last time. To say that a break was taken from machining is not strictly correct, as often a small amount is squeezed in to keep it ticking over. The eccentrics are all finished to the same standard as the one below just with the centre hole left rough. This is because I was having a nice new boring bar and tips for Christmas, so decided to wait for the new year to complete this. Attention turned to some easy machining in the bracket and oiler cup, a quick turning job from some Brass hex. I decided to thread the top with a tap I already had, but found I was not in the possession of the matching Die. To supplement my collection I have since ordered the Die in HSS from Tracey Tools so this will be a Birthday present (February) size : 1/2" x 32 TPI ME for information . The remainder of tim
Carbide Tips (Part 3) in use in the workshop Above the eccentric sleeve under way and used as a machining demo with a new tool and tip I bought. Finally the reason for the large diameter bar above, was to start to make the eccentric sleeve. As a way of demonstrating a reasonable cut on a small lathe, with positive rake cutters and slow feed. The Lathe is an Atlas 10F with I believe a 3/4 hp single phase Motor. The eccentrics are to follow after a weekend break in Blackpool !! Eccentrics started just required finishing and a grub screw to lock, the collar just requiring the curvature machining for the governor drive belt. Well a short one this month, and another day off at the end of the week to drive a narrow gauge engine on a pig farm! Next month continuing with these parts and perhaps starting the eccentrics outers made from bronze castings. Until next month stay safe; make swarf; have fun!
