possible oil bronze bushing for quill upgrade

I've noticed some are machining their quill casing to install a rear bearing. I've been thinking, since I can't find a bearing that will press in without machining, about getting a bronze oil impregnated bushing machined for this upgrade. The cost would be in the $30 to $40 range, that beats the $18...

Re: 1983 Mark V 1 1/8 hp motor failed

rjent, the price isn't the problem on getting a new headstock, room is my problem, I just don't have room for two machines. At my age I can't justify building an additional shop, even though that would be nice to have... I just regret that I can't take my tools with me when it's time to go. Great da...

If your Mark V is like mine, it may be failed motor windings due to age. My Mark V was working fine and I didn't use it for several months, but left it plugged in. I'll never do that again unless it is in use. Couple of days ago I went to the shop to build a custom loading bench and found the motor ...

FL near the lightening test research center. I think since my sheaves and everything else is in great shape, I'm ...

1983 Mark V 1 1/8 hp motor failed

I inherited my Mark V sn: SS1450440 from a dearly departed friend in 2003. I think I've used it more than he did for the 20 years he owned it. I like this old timer but the 1 1/8 hp motor failed. It won't even run on the test bench. The motor and sheaves turn & move freely, and have been cleaned...
