Harrison M250 Restoration

Agree, the one for the holders looks favourite, thanks @R-D-R

All painted and fitted with anti slip rubber matting

Its 20mm steel Kopex I had spare from another project. I think it was a purchase off eBay its sold by the mitre there for about £4. It is nice stuff and the fittings are nice and secure.

If I recall mines 316 stainless you can get it in different specs.

The Oil can is a neat little thing its a Eilang double pump works upside down etc and gets a decent pressure to push the Oiling Nipples.

The foam I'm not sure it came with the Enclosure I'm modifying.

Looks excellent, very professional job. It will really complement the lathe.

I don't think your braking resistor will ever be troubled by the work it has to do. Sensible to mount it as you have done though.

Looks "The dogs" but you have to finish painting that wall!

The whole thing looks amazing.

It's often a case with a project that you can end up in a position where you wish you'd spent more and bought a nice one to start with but I don't think it would have been possible to buy one as nice as yours looks now.

Thanks for the positive comments guys :-) away for the week now with work but hoping to get the VFD wrapped up next weekend. Grabbed 30 mins this morning and got the Mains supply cable plumbed in, drilled the lower air intake holes and positioned the VFD. Next job get the Contactor and Transformer in and start organising all the spaghetti !

Just an aside on the 600 Group. Very helpful spares sales department overly willing to help the little guys out. Prices are as expected for some items however I've been pleasantly surprised for the larger more important items. Reminds me very much of Car manufacturers pricing (LandRover in recent experiences) in that its always a surprise (either way) when you ask for a quote! I thought i'd add missing lever handles on to my order until i got the prices - £18 for one M10 push/pull knob so I found one with brass insert £1.80 delivered! anyhow excellent service. Also a surprise was their open policy on original drawing for obsolete items. If ever you need something its definitely worth calling them, if its obsolete they may have the drawing you can have (they emailed me them for free). Heres a couple of examples they sent me, quite nice to see and gives me some projects to attempt when i get it up and running...

Hi~ I have a same lathe in China, but many parts were missed, and its very hard to find any datum or part. If you have completely original drawing, could you please send me one. My Email:nismo999@foxmail.com

Well I didn't get much time at all this weekend but managed to get the bulk of the wiring installed, just some tidying up internally needed, i'm waiting on some DIN rail terminal block holders but its back together now so i can at least use it. Got to make a holder and mount the sensor for for the techo next.

All functionality back and working Foot operated Emergency Stop wired in, a front panel v3.0 needs making now with switch for coolant pump adding. Switched power for Coolant pump and ancillary power routed to rear for DRO and Lamp.

Got back from working away today and decided to get the rest of the wiring inside the enclosure done. Seemed to be never ending spaghetti but its done and all works. Fan filters are in place. Next job is the Spindle Tacho but thats all routed direct to the Panel enclosure.

 

[R-D-R]

spent some time today making some bracketry for the Tacho. I made a ring to fit over the spindle and countersunk the Magnet into it, I then made a holder for the Sensor that fits over the Change wheel cover bar. Threaded the Wiring (still to finish the Kopex routing) and it seems to work fine. Its a little fuzzy on the slowdown giving some strange readings which you can see in the video any pointers as to whats causing that i'd be grateful but its not a major issue just weird.

quick video of the weird readings on slowdown

whilst i had some 50m stock in the machine i then made a thumb nut for the change wheel housing, not sure exactly what the original looked like but this works for me
