Re: Bridgeport broken T slots

Brand new tables are still available from H&W for about $1500.00.

Re: How to Keep Planishing Hammer from Dissolving Thumbs?

That is planishing hammer, not to be confused with a power hammer. A power hammer would have left you with missing thumbs, instead of sore ones.

Re: Cone slip roll

Boyd Engineering used to make one like that. When I worked there, I found some of the old blanks, but haven't seen a whole one. The one they made was built for fabricating cones to make expansion chambers for two stoke dirt bikes and karts. I still work for Walter Boyd occasionally, and I can have h...

Re: MACHINE SWITCH

I feel for you about the 10 page manual with your VFD. Using your existing switches with a Hitachi, Yaskawa, Allen-Bradley or Danfoss level of drives would be doable with the options they have. I also have some old Bronco, Bodine and KBs, which are much more rudimentary in control circuit options. T...

Re: MACHINE SWITCH

Check the VFD manual in the control circuit section. There will be a provision for operating from the terminal strip, and a parameter to set it. In the same section, there will be an option for '3-wire' or '2-wire' control. 2-wire will keep a maintained contact switch closed for start on power up an...

Re: Crazy Deal on HF Planishing Hammers

Good luck with that planishing hammer. I bought one several years ago to help get more life out of stock car body panels. I would ruin anything placed between the anvils to the point that even a real planishing hammer would have a hard time taking the half-moons out of the sheet. After heating and s...

Re: Safe to Grind Tungsten on Bench Grinder?

I've run into the 'lazy at low wire speed and low heat setting' with wire welders a couple of times. It may be worth checking your line voltage, and verifying the correct transformer tap in the welder is utilized. Running a machine on 208VAC that is wired for 240VAC drops the open circuit voltage on...

Re: How stubborn are you?

Last year, I made keys for an F-350 after the originals were lost. I realize that I'm way too stubborn to ever learn not to spend a whole day repairing something that could be replaced for $50.00.

Re: What filler rod to use?

I've TIG welded cast iron with nickel 59 and 99, as well silicon bronze many times. These fillers always leave a noticeable color difference from the original iron, as they don't rust (really only important on restorations). For the last several repairs, I have been using old piston rings from small...

Re: KB Electronics VFD on Toolmaster 1B Mill?

I have used many KB drives. These are simple to set up, and and the Nema 4X case makes it even easier to do the installation. From my own experience, I prefer the toggle switch model over the membrane keypad. I just installed a KBMA series drive on a vertical bandsaw, after my old (2001) KBAC stoppe...

Re: Incredible Deal on an Induction Machine

This obviously an induction machine, a drill press would have had a drill press motor on it... I didn't notice if it was rated for use in all phases of production, or if was strictly for single phase use.

Re: Troubleshooting electric motor noise

Your problem may just be a single phase motor. I have run into the same thing myself with a contour sander I put together a few of years ago. After using three phase motors, which run very smooth, a single phase motor seems excessively noisy and has a very apparent vibration, even when working right...
