Thread: Harrison L5A 11" - VFD set up & spare parts needed |

Thanks for all your input guys, all taken on board, much appreciated. I have a little update: Handwheels - Thanks Alan for the lead on Bebe Tool and Machinery. Got in touch with them but sadly no luck. As expected the splined version is near impossible to find and they had to get some pattern wheels splined. So I have two 5" wheels on order and will use my existing handwheels for their splines. Most likely use them as bushes, remove the centers on the new wheels and seam weld them together. VFD/Motor - Took the motor apart to try and find the star point and I'm starting to think getting another motor might be the best option. Never messed around with electric motors and I'm getting a little scared looking in on all the windings. Seems a shame to just shelf this motor though. VFD arrived yesterday and I'm working my way through the manual. certainly glad I opted for a branded VFDs rather than the cheaper Chinese VFDs on eBay, the Chinglish manual would of really hurt my head.
There is a local guy who re-winds 3 phase motors, might pop it over to him and no doubt he can re-wire in Delta with his eyes shut, if it's cost effective. I'll keep this updated, no one likes a dead thread. Thanks! |

Hi guys! Had enough of the Clarke’s Lathe I had. I'm 27 and wanted something that would last me and still function. Haven't had the best experience with the newer Clarke’s stuff. Got a couple of their older grinders So bought myself Harrison L5A, believe it to be a MK4 but it would be great if someone knew a rough year. [img]https://i.imgur.com/O2w0u6W.jpg[/img]
[img]https://i.imgur.com/wBPgFH6.jpg[/img] However it's been dropped in its lifetime. Bed is mint but the saddle has cracked, having that welded at the moment, no real problem. But I'm having issue finding hand wheels. They're splined rather than just a keyway, would anyone know where I could get a tail stock and apron hand wheels? Or perhaps the same splined wheels are used on different makes/models lathes. Tail stock wheel: ID - 15mm OD: 5" Apron wheel - ID: 12mm OD: Nothing left to measure [img]https://i.imgur.com/YWAD1SU.jpg[/img] [img]https://i.imgur.com/6n8lkGv.jpg[/img] Secondly just seeing if there are any do's and don'ts when it comes to the L5A. I'm only on single phase at my shop so bought an Invertek 1.5kw VFD 1PH to 3PH, motor isn't dual voltage so as far as I'm aware it's pretty much plug and play. Going to wire it up and hopefully still use on the lathes originally buttons and levers, but are there an tips and tricks when using a VFD or with the Harrison L5 itself?
