Van norman boring bar - struggles around 20 thou cut?
What are you using to measure your bores with? Make me wonder when you said you had the lisle but not sure what you took out with it. As far as the bar power. Shop I used to work in had 3 or 4 Van Norman bars. I dont remember how the number system works. We liked to use the small bar to... -

Hardinge TM motor amp draw too high
Hey not an electrical type guy here but. It is a 2 speed motor. If you have your vfd hooked up to the high speed winding. And you have the low speed windings wires tied together would cause a problem. The faster you spin the motor the more the low speed windings try to put the brakes on...- mastuart

Questions on using a gang of slitting saws?
Thanks again Mountie . Blades with integral hubs sounds like the hot ticket but at what price. On the normal hollow ground blades. A flat parallel spacer in different diameters would need different thickness to maintain the .040 spacing between the blades because of the hollow grind. Also will... -

Questions on using a gang of slitting saws?
Mountie Thanks for the link, Could you tell me do you also have some kind of special spacers to use with saw blades. Looks like most blades are hollow ground. So would it be ideal to have special spacers to match up with the hollow grind . In my case I need 5 .040 saws spaced .040 apart. In... -

Questions on using a gang of slitting saws?
Thanks for the replies. This is being done on a Bridgeport type machine(Sharp) with a 2 axis cnc. So I don't have to crank the handles. Would it be better to do it in 2 passes? The dept of cut is .050 and the dept of the teeth on the saw is less than that. When I get back on them I will get a... -

Questions on using a gang of slitting saws?
Hey guys Your right about the wax. Tried some bee's way with and without a cutting oil. Plugged things up. I don't think there is enough heat generated during the cutting to keep the bee.s wax melted. So far Lube and a blast of air seems to work. If they are cut one grove at a time any way you... -

Questions on using a gang of slitting saws?
Thanks Milland. This is a job for myself a hobby project 18 cyl radial. Building it from a set of plans from Ageless Engines. Plans say it can be built in 2000 hours. Of course this is with manual mill with a rotary table and a 9 inch lathe. The part I am working on now they claim it takes... -

Questions on using a gang of slitting saws?
Hi guys. I have a little project using slitting saws. Saws are 1.750 dia .040 thick with a .040 thick spacer between them. They have 90 teeth each. The material to get slotted is 6061. The questions are. Is it better to clime mill or conventional mill with them? What way will give the best... -

WTB 3 / 4 / or 5 inch Kurt vise
I got a cheap shars 4 inch with swivel base years ago. It worked ok for somewhere around $100. Always wanted a new Kurt 6 inch. Got a 688 new. Looks like a lot better quality than the cheap shars but not sure it works any better. I miss the 4 inch vise. Might get one of the more...- mastuart

Foundry Can't Melt Copper?
If you can run that thing with out that small tank frosting up and losing pressure you are not using much gas. My furnace I use 2 20 pound tanks but mine uses a blower. I think it would be tuff getting much more than 4 melts out of 40 pounds of gas. That is to melt 8 to 10 pounds of aluminum... -

Foundry Can't Melt Copper?
Two things . I don't see a base block in your picture. New propane tanks have a valve that can limit the gas flow. Put together a bank of tanks to make sure your can supply more fuel than you need and the pressure does not fall off. If its cold out even 2 or 3 tanks can frost up and you will... -

Molybdenum disulfide paste lubricant
Some time ago I bought some storage cabinets and content from a tool and die shop that closed. This unopened can was in one of them. What are some good uses for it. Is it useful for taping? Just don't know if I will ever use it. I also have a couple of 1 pound cans of it also. -

Building a model size turbo jet engine
I enjoyed watching the vid. Might have been crude but he got the job done. Lots of guys with well equipped shop could not get the thing made and working. Back in the early 90's a miniature gas turbine was considered impossible to build even by Nasa. But a guy by the name of kurt Schreckling...
