Reviving a Lathe (Part 2 of 2) 

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.

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.

Ha haaaa, laughed out loud at the ribbon cutting ceremony. Another fine piece of work again Crispin.

Brilliant video Crispin. I envy you this lathe:) Thank you!

Fantastic to see you back. 👍

Welcome back, and thanks for the video. Glad, it was a broken house, only,. So nothing serious :)

Nice work crispin. Very envious!

Great to see you back on this.

Excellent video, great to see you back.

MrCrispin , ANOTHER GREAT VIDEO. REALLY ENJOYED IT !!!!

Mister Lion King, good luck with your work.

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...

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.

This is a beautiful machine, been waiting to see it's completion!

What a rewarding project...and to receive a free quick change tool post as well!

Mr. Crispin, glad to see you again in working order. One suggestion; you mentioned you made new plexiglass panels for the safety guard. Plexiglass is brittle and will shatter when a e.g. workpiece hits it. You should use polycarbonate for this application. This is tough and doesn't shatter when hit. In fact it's nearly impossible to break. CNC machines use this material too. Downside; it can react with coolant and become also brittle over time. In your application I don't think that's a big issue. Be safe. Btw; I hate these guards. Especially when your turning small work in a collet mounted in the spindle. On milling machines they're really annoying. Small mill in collet close to vice; no way josé; the guard interferes with the table and everything else. I discovered that the people who work on these machines install a secret override to get the work done... Don't tell the safety officer; he'll get you fired. (I think your guide doesn't switch the machine so you're able to choose when to use it. In companies and governmental shops the do.) All the best, Job

I am mostly a self taught machinist and found the video on matched paired metals very informative, thank you. From New Zealand.

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.

Excellent musical accompaniment to the cross-slide assembly. Go the US Marines!

Good to see you again, and congratulations on having the lathe look spick and span and do its thing!

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

Nice! Thanks Mr. C, nice to see you. So sorry for brother!

After nearly a decade of work as a welder, I started an apprenticeship with a machinist recently, and the Algorithm brought me to this channel, and I gotta say I love the content and have subscribed.

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.

Very happy for this latest installment. Wishing brother a rapid recovery.

Great to see you back 👍

Really enjoyed watching these restoration videos. Great job!

Well done Mr Crispin, nice to have you back.

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!

Thank you for coming back! It is so good to see you again. :)

Excellent Cris, you should be proud of the achievement and the lathe should serve you well for many years.

Lovely to see you back with another charming and informative video. Thank you Mr Crispin!

Good to see you back again, beautiful result

Excellent restoration work you’ve done it looks amazing. Looking forward to seeing your next video.

Great Video Crispin

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.

Great work on breathing new life into the old lathe, and love the little "hat trick" with the drawer-lol

cant wait to see some projects with it, so beautiful!

The work you are doing is top notch and informative. The music makes me think of an old industry film.

Very nice work to complement a well made lathe, cheers!

Great to see you back Crispin. Fantastic job on the refurbishment, looks and sounds great. Looking forward to seeing it in action. Cheers, Jon

Good to see you back. Great video.

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 😁

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 🙄

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

Welcome back!!! Thanks and all the best from Panama.

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 ! 👍

Great to see you back!

35:00 Nice varmint round 😉 Good to see you again Mr. Crispin. Great video! Good luck with the home renovations.

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.

Good evening Mr Crispin 🤠 A well worth waiting for video 👍🏻 it was only the other day I thought I’d not had a Mr Crispin video in ages 🤣 What a lovely bit of kit. I’m no engineer but I really enjoy seeing someone like yourself using and explaining what you’re doing in a very understanding way 🤩

Worth the wait, thanks MrCrispin.

Condolences to your brother. The lathe got the TLC it deserved and looks and sounds ready to tackle any job you can give it. Thanks very much for this every illuminating description of the work you did on this very handsome machine. I appreciate the efforts you make to share you expertise and experience with us.

welcome back and enjoyed the video immensely Thank You

What a beautiful machine!

Just discoverd this channel. My life is now complete. Thanks

Well done Mr C. Xx

Always worth the wait! Fantastic work sir.

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. ;)

Really enjoy your videos. Many thanks. Hats off to you.

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.

Beautyfull lathe mr crispin and very sharp work!

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.

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.

I was glad to see that Mr. C has posted a new video.

Regarding the inverter, I cant believe anything is beyond your expertise, wonderful work and an excellent informative video.

Fantastic to see you back again Mr Crispin. I hope the first job on the lathe is some lion deflection apparatus for your poor brother !

Mr crispin You did a great work on this lathe. 👍👍

Good to hear the hardback joke book has not been mislaid. Nice work, quite an ingenious keeper plate clearance setting method, quick in production. Hope house is looking good. Thanks for sharing

Thank you Mr. Crispin

All set up and ready to go now :) I see you also have a Deckel FP. I hope you're as happy as I am with it.

Welcome back great to see you again 🦘👍

finally a new video! thank you very much!

Brings back memories from a million years ago. I trained at the Rolls Royce Training School in Mickleover in 1974, and attended various workshops in Nightingale Road and Sinfin, as well as some other places, as well as Wilmorton and Kedleston Road Colleges. Most of these places ceased in be before you were born @Mr Crispin Yet here you are doing the jobs I once only dreamed of escaping from, and eventually did in 1980. And now as I plan the restoration of some classic Japanese bikes, I’m actually considering buying a lathe and a milling machine! The options seem to be Chinese tools of dubious quality, or something like a Colchester Student - once the stuff of my nightmares! I’m impressed by your rebuild of this Harrison. It now not only looks like a solid and reliable piece of kit, but a somewhat impressively improved one too. Am I jealous? Maybe. There is a third option. I was never a great machinist, and I’m a firm believer in the Clint Eastwood maxim regarding a man knowing his own limitations. So, if you’re local to me, and taking commissions, you might have a customer. Thank you for sharing the best lathe vid I’ve seen so far.

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.

Always entertaining and interesting thank you mr crispin

Good video. I bet those Harrison crossfeed screws are a fortune to buy

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.

Thanks for sharing 👍

Excellent video as always.

¡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!!

fantastic work, fantastic video - thank you!

Excellent stuff. The lathe looks like it will repay the many hours you have spent on it. Good idea to use a vfd as a soft start.

Nice musical arrangement:-)

Great to see you back and it was worth the wait. The lathe looks great and as time permits given no more machine rebuilding, we will see your beautiful steam engine come to life. It is a great channel and its very time consuming putting this content out which i am great full for. No apologies need as you still have a life out side this channel and its quality not quantity which your channel gives.

I do like your style Mr Crispin,alway a pleasure to watch and alway very informative. Did like hearing the Jones& Shipman in action.👍👍

We, the people, demand to know why the Mayor did not attend the opening ceremony. Nice video, as ever, thanks.

Top drawer Mr C.

Welcome back and a nice job as usual! (Looks like the coolant needs a clip on it.)

I'd love a modern machine like that Mr C! My Colchester is 80 this year, wonder if it would like a cake 🎂

Love the music

Nice to see another individual who knows what is really going on. Having the ability to put into words one’s intentions in such things is paramount in being able to properly present such a video. I salute your efforts. I have a 1986 Colchester 15x50 that needed much attention when it arrived. Appreciate your time and commitment to the presentation of this video. Also, I notice there looks to be an Ainjest Threading attachment. I do not chase threads very often and have yet to use it. I’m accustomed to using the typical dial type thread chasing and have yet to investigate this different approach. As I understand it the Ainjest is great for threading up to a shoulder. Be great if you showed how this unusual threading attachment is properly operated. Thank you.

I found it very interesting, Thank You very much.

well done MrCrispin

3:36 - Very clever solution. 35:06 - Did fit a X-Y DRO to the Bridgeport knock-off several years ago, and it was equally a fiddly mash-up of available space, vulnerability and milled adapter plates, but well worth it. Counting cranks and inking marks on masking tape seemed a bit amateurish and they cost several re-dos over the years. The X-axis power feed took longer to fit to the same machine; turned out to be better compromises all around. The power feed, by notes, took 18 months of on and off work. Hard work with only a mill file (wink)... Wish I'd have fitted a 2-axis DRO to my 'new' lathe 8 years ago, but it takes a rigging company to move it away from the wall to do so now, so stops will have to suffice. Strangely the seller of the lathe (Grizzly) offers only generic DROs; no better than you got or what got fitted to my mill.

It's a pleasure to watch you work; generally things go very smoothly. It occurred to me... things tend to go well largely because you take so much care to think it through before you start the physical effort. This might be a matter of personal brain wiring -- other approaches also seem to yield success, e.g. "dive in and invent the solution on the fly." I prefer planning, so... thanks for the examples!

Very nice.

good looking machine.. well done.

We see you like Haley's Comet "for your occasional return". Good to see you
