My saw (1968) was originally a 1HP I believe, and then was upgraded (1972) to something else, but the motor plate was missing so it wasn’t clear what was on it. I was able to use acetone to get

TJ, thanks for the details on decel. as for derating, we have discussed it here. in fact, my RL (5HP) is run by 7.5 HP VFD. as you said 3HP is typically the limit where a 3 ph VFD could be used with 2

I've never seen a 20" old iron bandsaw with larger than a 2 hp motor but they have a lot of torque as the rating is at 900 rpm. To fit my lathe, I needed short resistors but could fit several so I

Yep- a custom knife in an insert head would be how I would do it, assuming you can build up the profile ie the lower and upper sections don’t need to be milled to the face level. Or just apply a

Look for a local tool and cutter grinder shop that sharpens and makes custom tools for machine shops. I needed a real shallow angle on some aluminum parts so bought a cheap 2” diameter spoil board

Michael, I imagine cheapest would be a cutter like felder safety cutter that takes blades with profile. i cannot imagine it would cost more than $150 for a custom profile 3/4” tall with two sets of

It took a while to find out the correct resistance for this drive due to lack of documentation – I think it turned out to be 43Ω. A matching resistor from Automation Direct was about $125, but

I chatted with the Automation Direct tech support guy about this and he suggested cranking the decel time down until the drive complains. Mine seems to not throw an error message; it just does what it

Hi folks, ??? I'm adding electric window openers to a set of casement windows in the cupola of a building I'm working on.? I'd like to keep the existing screens.? To do this, I need to change as

Thanks for all the great feedback folks.? In a way I'm a wee bit glad the solution wasn't intuitively obvious to my fellow woodworkers.? Imran is correct in his illustration above; I am interested

I put external brake resistors on my lathe. I found four 25 ohm resistors on ebay for $50 total and wired two in series and two parallel to keep the ohm thing correct. I mounted them in a different

TJ, that is good info. i have never explored braking on the VFD that runs my RL125 but i believe it works the same way and supports ext. braking resistor. just curious, how does your VFD communicate

The VFD does indeed provide internal braking, up to the current limit of the switching devices. Without the internal braking it takes maybe 50 or 60 seconds to wind down. A braking resistor in theory

The wheels are cast aluminum. From: "[email protected]" <[email protected]> on behalf of "imranindiana via groups.io" <imranindiana@...> Reply-To:

TJ, considering the size, i am surprised with 7 sec stop time without braking. does it have CI wheels? imran

Also, I agonized about using a braking resistor, but after doing a mockup and playing with deceleration time in the drive, I found that the drive can stop the wheels in about 7 seconds without an

Thanks all for the feedback. The parts are from Automation Direct. My constraint was that I didn't want to exceed the existing footprint of the saw with a big VFD enclosure, and the logical place to

Wow, that is a super clean install. Ive wired a few VFDs, but mine are just in plywood boxes next to the machines, lol! Were those enclosures and switches plug and play with the specific VFD you

Well done! Marlowe

Wow TJ , super nice - this is totally what I need to be looking for Regards, Mark https://www.instagram.com/kessler_woodworks/
