Re: Pump problem on horizontal band saw

A BIG thank you to all - the pump (and saw) is back in action. Now I can get back to planning the cuts. Apart from the engineering and the manufacturing processes to make the rotor this turned out to be a very simple machine. There was nothing fancy. The water goes in the center hole, the plastic va...

Re: Pump problem on horizontal band saw

I took the bottom of the pump off to see if the rotor turned (it did) and anything was clogged. The picture shows it upside down with the cover removed. You probably know how it works - the coolant enters through a hole in the center of the cover (Right arrow) and the rotors push it up through the t...

Re: Pump problem on horizontal band saw

Attached are three pics. The first one ('Saw') is a pic of the saw (a bit out of focus) where the yellow arrow points to a red toggle that controls the coolant flow. It is in the off position. Saw.jpg The next one shows the other side of the saw and the coolant bucket - i removed the stainless mesh....

Pump problem on horizontal band saw

I have an old Jet 7 x 13 horizontal band saw, bought used years ago, that has been a great boon to my work. When I bought it the 'coolant tank' was a plastic bucket with a pump in it and some stainless mesh duct taped over the top of bucket as a strainer. Recently a friend was using it and accidentl...

Re: How should I cut this?

In my relatively limited experience with RT work you need at least 3 clamps, 4 are preferred. Given that you are milling almost a complete circle you will have to reposition clamps. I try to have 4 so three of them can remain clamped while I move the 4th. You might be able to have one on the L side ...

Re: Troubleshooting coolant pump

Thanks for all the information. I did determine that power is going to the cap, and that the pump vane (connected to the motor) turns easily. I am going for the easy repair - replacing the cap - before I start taking more things apart that I might not be able to put back together. The only problem I...

Troubleshooting coolant pump

The coolant pump on my horizontal band saw stopped working - it just hums. Replacements are very pricey so I would some help troubleshooting - and my theory is the capacitor. I have a voltage tester but not entirely sure what to test. Specs: The capacitor is 4uF, WV is 250 VAC (guessing this means w...

Re: Stacked set screws ?

Thanks to all. It is indeed a cup point set screw so the first thing I will try is grinding it to a flat and better loctite. I am using the medium strength - did not want permanent strength but I guess if it fails the permanence will not be a concern. :D Good guess about the dimples so that might be...

Stacked set screws ?

I have a fancy brass door handle that keeps coming off its (square) steel shaft. It is held by a set screw that loosens over time. Threadlocker only extends the period a bit before it loosens again. I know that my Logan lathe has a few places where two set screws were used - and they were stacked on...

Re the Acme screw extending below the base of the machine: it is not obvious in any photos or even in the parts list diagram. It becomes VERY obvious only when you try to move one.

Re: Shipping A Benchmaster.

One thing to be careful about is the knee. There is a screw - Acme if I recall correctly - which raises and lowers the knee when you turn the knee wheel. This screw extends below the base of the machine. This makes it difficult to bolt it to a pallet unless there is some blocking to raise it. It is ...

Re: How to tap small holes

I am very much an amateur so others may give better advice but I have drilled and tapped a number of holes smaller than 1/8" and about 1/2" in depth in mild steel. I used hand taps and a bench block to ensure the tap was held perpendicular to the hole. The taps I were bought used at an est...
