Adcock & Shipley milling machine restoration - part 12 (completion of overarm support)

[@andrewdolinskiatcarpathian]

Thank you Clive for such an interesting and inspiring series. I am sad it’s over, but equally delighted for you that it all came together so well for you. Well done! 👏👏👍😀

[@Workshopfriend]

Thank you, Andrew! I hope something can replace this - perhaps Colchester lathe related. Will see!

Hi Clive, It's been a real pleasure watching this rebuild as my uncle had the same machine but possibly a tad older as the power feed was a 3 belt pully. Plus the real odd ball for us was the 18/8 degs taper we found out, not 40 int but about 35. His machine was imperial. His machine had a rack on the table if you disengage the half nut. 1 major down side we had was it was well before VFD where though about or inverters hence a small 1 hp single phase motor been fitted by us. Memory's oh Memory's Look out for a 1 inch arbour tooling easier to get. Steve

[@Workshopfriend]

Thanks, Steve, for your feedback. I haven't heard of that taper. There still seem to be quite a few A&S small mills of various vintages in home workshops. Yes, you are right about the 1in tooling. My 1 1/4 arbour also feels unnecessarily bulky.

[@carlwilson1772]

That was superb. The final outcome was well worth the work put in in terms of calculations and manufacture of tooling going right back to the casting in Pakistan. It literally could not have been any better. You must be incredibly pleased. One of the things I really enjoy is to see the calculations borne out in real engineering practice. A lot of my training and education involved the textbooks of Chapman and he emphasises this approach. It is something I have tried to pass on in my own small way. It will be interesting to see the shipping of your Colchester Student. I am glad you sold the ML7 and it has gone to a good home. I have always thought machine tool ownership is a bit like having an expensive watch. We don't actually own it, we are looking after it for the next person..I wish the previous owners of my mill had thought that.

[@Workshopfriend]

Thanks, Carl. Yes, there was a degree of satisfaction in seeing this project completed. I will bear in mind your comment about the calculations. The lathe shipment preparations are under way. I have ordered a crate to be made in Karachi and have a quote from a shipping agency door to door. I still need to find a way to load a box approx 800kg onto a truck... will see!

[@carlwilson1772]

@@Workshopfriend I think it will be worth having forklift truck pockets incorporated into the design of the crate you are making, I'm sure you've done that anyway. Gives you options. You can use forks to lift it or you can sling it there to lift it on a crane. Also allows you to pallet truck it onto a tail lift to get it into a vehicle and out again.

[@Workshopfriend]

Yes, it will have a regular pallet-type base. Actually, it will be a box not a crate to offer better protection. Been thinking about rust prevention.

[@HaxbyShed]

Technically interesting thank you. Yes I would be interested to hear about the journey of the Colchester Student from Pakistan. Cheers

[@Workshopfriend]

Thanks, Paul. I am not sure how I will video the transportation of the lathe. It is hard enough to video myself while matching in my own small space let alone working with others to organise a shipment.

[@SteveCallaghan-j4j]

Fantastic - always a pleasure to watch. Cant wait for the Colchester as I also have the exact one with all the attachments.

[@Workshopfriend]

Thanks for your comment. Good to know you are still viewing the channel!

[@KerstinVolkmer]

Great result! Already looking forward for the next video👍

[@Workshopfriend]

Thanks, Kerstin!

[@ianwhiteley964]

As always, a real pleasere watching a perfect restoration project. very informative and loking forward to the next one.

[@Workshopfriend]

Thanks, Ian. I wouldn't say it was perfect. Glad you appreciated it!

[@davidbawden6567]

A superb way of work holding & how to do the job at hand....

[@Workshopfriend]

Thank you, David. It was a gift of a set up really!

[@machineshopatthebottomofth3213]

Great work on this Clive, looking forward to the next project

[@Workshopfriend]

Thanks! As always I appreciate your feedback.

[@neffk]

It's a pleasure to see a job done well. The calculations, though elementary for engineers, do not get much coverage in video format. I thought that was a useful addition. And for those of us who have done many such calculations, it was good to see you check the theory with measurements. If I may pick a nit, when you use abrasives on the lathe, whether woven or non-woven, a small piece in one hand is better. I hear that KZbin is awash with caution comments, written from armchairs around the world but accidents still occur. The end of a smooth round workpiece is a lower risk than the interior of a shaft with a protruding pin but still.... Also, keep in mind that the non-woven abrasives are simply abrasive grains glued to plastic fibers---they drop abrasive grains everywhere with almost no provocation. Thanks for the video series and I'll be looking forward to whatever comes next.

[@Workshopfriend]

Thanks for your comments. Since I have received positive feedback on including calculations I will see if I can continue to include them at an appropriate level - from time to time. Yes, your comments about using abrasives are noted. I certainly do not want to encourage bad practice. Also, I am normally careful not to allow abrasive to fall on the bed by placing cloth on the bed. But that might also be considered a safety concern?

[@carlwilson1772]

Even elementary calculations can be illuminating and can very often be surprisingly accurate. It is an approach I share and commend.

[@JustPrinted3D]

I always enjoy your explanations and precise work

[@Workshopfriend]

Thanks, you for your feedback.

[@darynradcliffe2909]

Lovely job 👏

[@Workshopfriend]

Thank you!

[@constantinehatzis2807]

Beautifully done sir. Just an idea for oiling of the bush...I have a lovely Centec 2A with vertical head, raising block and overarm support, the bush is lubed with a dashpot at the front of the arbour support, this makes it easier to keep a check on the oil level. Also this may somewhat reduce swarf contamination that a side mounted dashpot may suffer? But in practice I'm sure side mounted will be fine. Looking forward to seeing the Colchester move, I took have an old student , it was a task just transporting it about twelve miles, let alone a few thousand. Hope all goes well.

[@Workshopfriend]

Thanks, Constantine, for your feedback. I like the idea of a lube arrangement which is visible. I think this deserves a little more thought. I keep wondering if there is something practical which will scupper the lathe move!

[@willemvantsant5105]

The K&T mills have an oil reservoir and sight glass, total loss oil system gravity feed system Space would be a constraint with yours, a simple oil drip feeder with reservoir and sight glass with adjustabe rate would solve the lubrication of the spindle. I use one on my homemade slotter to lube the dovetails on the ram, bit messy but works.

[@Workshopfriend]

Thanks, Willem, for your comment. I believe I have seen oil reservoirs built into the casting which seems like an elegant solution. I might end up with a parking frame which keeps the stored support arm vertical so something like this might be possible!
