In this video I show the completion of a Harrison 190 overhaul. This includes the completion of the mechanical assemblies as well as the installation of a Digital Read Out sourced from M-DRO
The installation of the digital inverter was greatly assisted by Paul Compton who's RUclips Channel can be found here:

Great to see you too haven't been bitten by a Lion and are able to release a new episode. Whilst I appreciate your brother was bitten by a Lion have you tried Tiger Balm I'm told it can be a great help in cases such as you brothers, he could also use it as a toothpaste, if you give him his tooth brush back.
Good lord man, you can't put Tiger balm on a lion bite, you'll kill him. Tiger bites only.
@@caskwith Wooh, you're right, Tiger Balm will sting !
@@thetrevor861 , I'm glad you got THAT straightened out!
Glad to see it come together. After your previous video I thought you'd be done in a few weeks.
A few years ago while looking for a large lathe (10 HP or so) I found a Harrison 450 in good shape. In Canada
Harrison lathes are not too common, this is the only one I have ever seen. It had a wide range of spindle speeds and gear box settings and needed little work so I bought it. I don't think it had seen much use. We had to repair the spindle brake, and found a loose roll pin in the spindle gears but little else had to be done. I made a big steady rest for it because that was missing. I put a Newall readout on it and made a hand crank gear drive for the tailstock cause it was too heavy to move. Most of my activity is on a Hardinge toolroom lathe but this brute
takes over when the job is big. I'm still working on the hat.
Welcome back, and thanks for the video. Glad, it was a broken house, only,. So nothing serious :)
This is a beautiful machine, been waiting to see it's completion!
Mr Crispin - I’m concerned about your brother. Are the meds recommended by the pharmacist working? Why not consult Quinn the Blondihacks lady - she looks very competent.
Brilliant video Crispin. I envy you this lathe:) Thank you!
I now see why the Harrison lathes are so sought after. The rigidity of the cross-slide and compound looks to be impressive. What a well thought out design.
¡Enhorabuena! (Congratulations!) A great video and well worth the wait! Very enjoyable to watch and a fantastic result, you must be very proud. Now about that steam engine .......
Good luck from Spain!!
Excellent Cris, you should be proud of the achievement and the lathe should serve you well for many years.
Great video Mr Crispin. I have the M-DRO on the mill. It came with a clear cover, which I always leave on. Protects the screen etc. I have some 3ph to 3ph inverters from when I had my sparky business. I need to get them sold. As they are good quality Jaguar items. When we wanted to limit current spike on startup. We fitted soft start units. Much cheaper than a inverter. Regards
Steve.
Its a pitty you are back, now I have to wachts al those boring video,s you produce again.
About twelve years ago I had a similar problem to you. A 7-1/2 hp lathe without a clutch in a residential area with a rotary phase converter. I shared a transformer with twelve other houses and every time I started the spindle on the lathe the lights dimmed in all thirteen houses. I looked at a few options and settled on building a pneumatic clutch for it. It took about a month to build and install. I was very lucky that it worked properly right from the beginning (anyone who designs and builds thing knows this is rarely the case). Ironically about a week after I got it installed the power company came by and put me on my own transformer, making the clutch somewhat redundant. I am now back in a shop in an industrial area with a proper three phase power supply. However, the clutch has not given me any trouble in twelve years so I have no plans to remove it. If you are interested I give an overview of my lathe and the clutch in this video: ruclips.net/video/LU4RNPjfKbs/видео.html . I think you did a great job overhauling your lathe. Installing digital readouts on older equipment can be quite a challenge. Ken
Thanks
Great overhaul of a very nice lathe. Paint doesn’t add much to the serviceability of the lathe and I hate painting. However, I love the looks and feel proud of my equipment when properly presented with a new paint job. Please consider a IGUS cable carrier or equivalent for your digital readout cables and coolant hose. I installed a cable carrier on my Clausing Colchester lathe in the chip pan area behind the lathe bed and it really protects the cables and neatens up the installation.
Nonsense. Don’t you know that Battleship Grey kept Britain’s engineering industry afloat for nearly 100 years - until the world bank decided to back the alleged losers of the last international contest: Japan and Germany?🧐😎😜
Peace
Very nice fitment of the dro . I see it has the typical quirky Harrison vee arrangement for the cross slide , some had inverted vee ways ! 👍
Nice! I'd love to know more about how the VFD/Inverter was set up. I recently worked out how to configure a single phase inverter for a single phase motor, and I'm loving the control it gives me, but I'm lost in the maze of options, and I'm sure I'm missing out on some of the possibilities.
Ok, I'll see if I can do a video with a bit more electrical info.
You may be interested in this 7 part playlist by Clough42. He went through the whole process of installing, programming and interference shielding a VFD. ruclips.net/p/PLDlWKv7KIIr_Znhfg8obxwcduFee5Ub5z
@@M_Northstar Thanks, that's potentially really useful. Clough42 often goes way deeper into things than I have time to watch and properly absorb, so I think I missed this one.
Really glad to see you back! I was wondering just the other day where you had gotten to. Sorry to hear about you’re brothers incident. Has he tried sponge bob square pants plasters? I remember them solving all problems when I was younger.
Nice work crispin. Very envious!
We, the people, demand to know why the Mayor did not attend the opening ceremony. Nice video, as ever, thanks.
Ha haaaa, laughed out loud at the ribbon cutting ceremony. Another fine piece of work again Crispin.
10/10 AAA+++
Fantastic to see you back. 👍
I knew you were lion about your brother. You need to sort your priorities 😉
Looks ! Like ! Those Vice Jaws ! Are !! Way !! Out !! Now ! So ! It looks ! Quite !. Stuffed !! Up !! Here !! COMPLETELY !!
• Inductive loads.....inrush currents
• Stroboscopic effects.....use a high frequency lamp over machine tools and rotating machinery...
🇬🇧😐
Love the way you present your content. Subtle humour, easy to understand, and always great machining results.
Your VFD/VSD I notice has the 'Normal' whistle when ramping. There is a setting (in most drives) where you can raise the switching frequency to take it out of the audio range if it is annoying. If not annoying, then there is no need for parameter adjustment.
Thanks for your content.
Cheers
Pete' New Zealand.
Thanks!
Why did the finger pointing remind me of Monty Python???
Good to see you back! I eagerly look forward to your future videos! I also like how you used the inverter to provide a "soft start" for your lathe -- I'll have to keep that idea in my "toolbox" for future projects if/when needed. (It reminded me of the "soft start" for the "small" wind tunnel I relocated from across the country & installed at work back in the '90s: it ran/runs(?) on 4160 VAC, 3-phase and still pulled ~1500 amps at start-up while using the "soft start" equipment and ~300 amps steady state. It really made the CNC shop angry at first because the surge could cause "problems" with their machines. However, the Facility Electrical Engineer did his magic and "fixed" the problem well enough to minimize problems around the wind tunnel. ;)
Interesting!
I'm glad you're back and also glad to imagine your home 'machinery' is receiving the same attention to detail as your workshop tools. I particularly like your choice of music for the montage sequences- much better than the all-too-typical Rock and/or Roll we normally must endure...
Yes I was pleased to find it.
Reminded me of fairground from when I was kid in uk
Very nice work to complement a well made lathe, cheers!
Thanks for sharing 👍
I bet the flat mount base from the tracer had a twist and pulled the cross slide to wear on one side
Yes flat mount base indeed.
The finished lathe looks absolutely amazing and appears to run just as well as it looks.. not jealous at all! 😂 Look forward to seeing it break the odd chip 😁
I was wondering what happened to you. I feared the 'Rona got ya! Just curious....did your brother bite the lion back?
You sir are something else indeed. Ribbon cutting ceremony, coat & tie, how very British! I must say you have accomplished a nicely done restoration Mr C. While not familiar with Harrison machines, it seems like a very nice and capable lathe for your workshop. Cheers from NH USA
Thanks.
Harrison are Clausing lathes in the US. at some time, there was a partnership.
I am mostly a self taught machinist and found the video on matched paired metals very informative, thank you. From New Zealand.
I have a new favorite song! Or many of them, but... they seem difficult to distinguish... perhaps interchangeable. :)
I can't help it; everytime that music plays at the end I expect a giant cartoon foot to come down with a squishing sound...
Love the job on the lathe.
Harrison, isn’t that a Colchester of sorts?
It’s a quality built machine tool.
I have a 1974 Triumph 2000 which I am rather fond of.
Cheers,
They originally were different companies but yes they ended up under the same banner which was and still is 600 group.
Hope the lion is feeling better after his traumatic experience😃 👍🏴
Welcome back Mr. Crispin! I thoroughly enjoyed your new video. I did, however, have to watch portions of it several times. It seems the old military man in me found it impossible not to break into a march around the house when the music began (Sousa I believe?). I finally muted the sound and was able to watch the entire video. I've missed your expertise and your humor.
Good to hear!
I felt an urge, too! The US Marine Corp Band played all four numbers (see "Show more" in the description - I had to know!).
MrCrispin , ANOTHER GREAT VIDEO. REALLY ENJOYED IT !!!!
When the background music played, I expected Winston Churchill to make an appearance.
Excellent musical accompaniment to the cross-slide assembly. Go the US Marines!
I subscribed just for the lion joke!
By the way is the lion O.K.?
Life is what happens while you're making other plans! Good to see you back, and we trust we'll see your brother fully recovered sometime soon 🙄
Dear Crispin, Quinn (Blondihacks) just told me one of her tools is actually your brothers toothbrush!
She made me laugh out loud, your brother must have brushes on stock. haha.
Glad to see you're back! Lathe is looking great. I've used M-DRO for the encoders on my lathe as well, they're very convenient. You've maybe come across them, but they also have a magnetic tape style of encoder - compared with the glass scales, the huge benefit is the head is totally non-contact. E.g. the way I've got things set, I can slide the cross-slide off for maintenance without affecting the alignment of the encoder. They're much easier than the glass scales.
This makes me feel much better about having taken up a huge lathe resto and already having had over 7 months run by me... I thought i was a bit too slow, which i am, and a bit too lazy, having taken weeks of breaks in work at a time, but seeing a bit smaller lathe than mine take as much as it did you, i will chalk up my wasting of time as time spent in caution to get things just perfect... None of it is helped by the fact that i just took up a surface grinder to get back into shape, before taking on restoring it fully... Also, if you get an ELB/Aba surface grinder, the company is still existing and running well, but it appears to have a cunt approach to users of its olden machinery in regards to inquiring your tax nr. and address and then promptly not answering you again... I asked for bloody lubricant recommendation as the spindle ``runs`` kerosense or paraffin as lube, which in my mind was a big no no, and all i got was ``do not run kerosene or paraffin as spindle lube!`` with no further answers... Also, no answers in regards to their available spare parts stock for the machine despite giving them the machine serial nr... I took mobil velocite 3 for spindle as its a zero clearance tapered bronze bush with forced oil feed, so i guess its as close to kerosene in regards to viscosity but actually being a bloody lubricant and not a solvent...
Oh, a nice job bringing the lathe back to a lovely state! I suppose a compliment was in order after my bitching about my own troubles... And one thing, i would not have used the sandpaper to grip that oil fitting... I at least hope you cleaned it well afterwards... Sandpaper of any sort is like a leper, sheds its grime and disease all over the place and infects anything it touches... Its good for grinding on a flat pane of glass, but in my shop, there are no abrasives of any kind, except for maybe my attitude and mood...The grinders and abrasives and a polishing lathe are enclosed in their own little solitary cell as they are like the life serving inmates that dont mind murdering others around them for fun... Not something i can have roaming the shop while in not looking, spewing grit and abrasive particles about...
Some strange civilian, with a tie and a pair of scissors suddenly appeared? Ah, so sorry! At first I thought it was your brother, but then I realised, there were this lion incident. I always get confused, when people suddenly wears something else than the well-known working clothes. 😄
Lol, after 15 years of machining I decided machining wasn't for me and sought other endeavors. I soon discovered I wasn't as good at these other endeavors so now 40 years of machining/tool maker here I am still slinging hot chips mostly from a Harrison lathe.
I would love a nice Jones and Shipman 540. I have a small Eagle surface grinder and an old Brown and Sharpe but both need attention.
Tiger Balm is best for Lion bites.....I'll get my coat😂😂
I would suggest changing doctors the mosquito spray will not work on a lion bite. Perhaps some liquid band aid would be best.
Great stuff, how's your Brother?
What a rewarding project...and to receive a free quick change tool post as well!
Hi Crispin, watching this again and I noticed that you have a Deckel milling machine. Which version is it and how do you find using it?
Well Done Crispin. Great Outcome. I Loved The World War 1 Style Of Music. Right Up My Street. Your Own Music Or Stolen From The Internet ? Regards From Australia.
Just something I found on the RUclips royalty free Library! Cheers Dave.
Wise choice to use local suppliers. A mate of mine imported German stuff only. As soon as he picked up issues he had to import information and or tools, spares etc. Etc. What a dummy!!!
If he was badly lacerated in the attack perhaps tiger seal would make a suitable field dressing ?
Excellent work as always 👍🏻
I found it very interesting, Thank You very much.
Our local police have the phone in a filing cabinet draw. The difference is it's permanently locked because they never feel the need to answer it..
So good to see you again, wonderful lathe refurb looking forward to seeing you back in the workshop.hope your brother did not infect the lion ! Thank you
Excellent restoration work you’ve done it looks amazing. Looking forward to seeing your next video.
Sir Gareth good work so video totally good making somuch sir
welcome back and enjoyed the video immensely Thank You
Great to see you back! What were they smoking with that cross slide way design?!
As usual I wasn’t listening correctly ! Sorry crispin it was a lion you said not a elephant? And the lion beetle is a real predator .
Congratulations, Crispin. I know very well what it’s like to have too many projects on, and what a relief it is to cross off one or two. And thanks for a good video!
Mister Lion King, good luck with your work.
Really enjoy your videos. Many thanks. Hats off to you.
Yes, I can see you have been busy, too busy to shave that upper lip. Your too young for that hair.🤣
I do like your style Mr Crispin,alway a pleasure to watch and alway very informative. Did like hearing the Jones& Shipman in action.👍👍
Thanks
And don't confuse _midge cream_ with _minge cream._
Pink...
They were Pink..
Yes, I checked!
Pink scissors, how could you?
Lookin' good there with the lathe.
Sooo many ways to do any job, liked your thought processes re the DRO.
They are actually red! However the sun has got to them!
Nice! Thanks Mr. C, nice to see you. So sorry for brother!
Hey this is still going faster than that scale locomotive! 🤣 Staying busy keeps you out of trouble and from getting bit by a lion.
If the crossfeed has one thou rockin, don't bother knockin.
I always enjoy your content. Glad you are back at it.
The attention to detail is real. A lot of thought goes into all of your work. Respect.
Really missed you and the "Harrogate" Doncaster show where I had a quick chat with you years ago. Roll on 2023 when Lou might organise another show in Doncaster.
Yes hopefully they resurrect it.
That top slide rock, I would be tempted to blue up the ways and move it an inch or two back and forth to see the contacts patches. Might be you have a high spot you can stone.
Good idea
Great to see you back Crispin. Fantastic job on the refurbishment, looks and sounds great. Looking forward to seeing it in action. Cheers, Jon
Thanks Jon hope you're well
Good video. I bet those Harrison crossfeed screws are a fortune to buy
I'm sure even if Nigel Mansell had a Harrison lathe he wouldn't have overhauled it any quicker! The assembly pin/bolt for the 'gib' plates looks to be a right old faff, but nicely done, thanks for sharing.
Great Video Crispin
finally a new video! thank you very much!
so great to see you again - all the best to you 👍👍😎👍👍
Could you be so good as to guide us on a tour of these home improvements?
The best custom DRO instalation video I've seen on the Tube yet. Great job taking us through the process of finding the right surfaces to drill & mount the equipment and why. Much respect from Texas, MrCrispin.
Thanks
Not to spit on Crisp, as he did very well, but did you look at Robin Renz`s dro installation on his hardinge? That is a masterclass on dro mounting with physics explanations and all the possible shit taken into consideration while doing it...
An interesting metric -english conversion -- 25.4.k subscribers.
Very good!
Next time you go for a walk with your brother, get him to leave his stick with it's horses head handle at home. That way he can't be poking any lions with it - it makes them bad tempered
I think Stanley Holloway offered some similar advice
Love the music
Do you have video of you at 5 with your voice, overalls, and (unusually for your age) 'tache?
I take it you are wondering if I look exactly the same!
Whats the treatment for that?
Nice musical arrangement:-)
Albert Ramsbottom was bitten by A lion at Blackpool.
Stavros
A Stanley Holloway Classic which I happen to know all the words for!
I drilled and tapped and remounted my PM1236 cross slide DRO from where the importer located it. Not to look neat [as was] but so if the cross slide is advanced until the screw disconnects that cross slide is pushed until backsplash contact.. the glass scale will not be broken.
Excellent video. A beautiful machine which solicits no envy from me whatsoever. Many of the constructional features are similar to my Maximat V10P, albeit at a much larger scale. I particularly enjoyed the music, made me feel I was back on parade.
Best wishes, Dean at Retromeccanica.
Wicked moustache!
I’d give this video three thumbs up but I’ve only got two! Best wishes to brother!
Thanks
