Cold Iron

Yes radiant heat will also warm the 'machinery' as well as the operators. It works well in places such as warehouses which would be prohibitive to 'heat'. So perhaps you are better with radiant heater, but don't complain about the air temp! I would think rafter mounted radiant heat would be needed t...

Dc Motor 'short course'

A DC motor has the following things going on when running: A Magnetic field is created either by a magnet or a field winding. For the most part(there are exceptions) these motors also have an armature with additional windings. These windings are connected to by way of brushes or some other commutati...

Reflective Heater

Put a small fan near heater to move some air around it. Reflective is alright if you are trying to warm people who can feel it, but they are not very effective at warming up the atmosphere.

i.e. Radiant OK for people, Forced air better for heating shop!:D

"Idler sheave not control sheave"

I stand by my previous post re IDLER sheave/Control shaft wear. Only the CONTROL Sheave "slides back and forth on the shaft". Yes the key/keyway slot DO become worn(I have one to prove it, but it took 40+ years to do so).... Proper lubrication would probably have prevented it! The idler sh...

SS Chuck

Jacobs (in their on line info) list a 3328A with a .625 mount. That just happens to be the 10ER model(works very well on mk v). This is from their "Professional keyed chuck" list. The 'Jacobs Multicraft chuck MC8K26' is the current SS chuck, but is NOT listed in 'Multicraft' list. So we mu...

"panic" parts

I am not going to say what I would stock up on as I already have. A good starting point is "The 17 Most Frequently Ordered Mark V Service Parts"! Check threads on this forum for "things" which become problems. I do not at this time see a need to stock pile. I was SO relieved to '...

23/hot shaft

In session 23 Nick says" about 1/8" deflection of belt is right. He also said to adjust eccentric to 'just tighten' belt. Does your intermediate shaft eccentric also have the set screw as well as the housing clamp??? If the set screw is too tight, it will put pressure on the bearing(Bill a...

Clip/Springs etc.

Finally got time to check the speed increasing issue on my 500. In all I found 3 parts, the retaining clip, which is broken, a small spring and a roll pin about 5/8 in long, doesn't look broken. I'm calling it a retaining clip but not sure its real name. I have replaced the belts before and remembe...

Pix ???

I am possibly confused. Your pix clearly shows a retaining ring and what appears to be the 'button' on the end of the pork chop end on the control sheave in the last three views. In all of the other three the retaining ring is where it is supposed to be! I am going to assume that the ring etc. fell ...
