Thanks John, Every now and then I conduct a search for Quorn Tool and Cutter Grinder, usually with a bunch of irrelevant results. A few days ago I finally struck gold with 4 or 5 channels, I'm working through the videos. The half hour I have just spent watching this video is the best use of time I've had for a while. Several years ago I purchased a completed Quorn in similar condition with similar errors. I cleaned it up and fixed the show stopper errors. Of course the rust came back to visit, I see some 303 SS in my future. I will also convert from existing collets to ER series. I will watch this video several more times and cast a critical eye over my little machine again.

Hi John, Thank you for taking the time to document your restoration, This is saved in my G Thomas folder for reference. Regards Beagles.

Great project. Thank you for sharing the details of your restoration. Look forward to seeing the finished result.

Thanks for sharing this video, John! I really like the idea of using an ER collet holder. I am just about to machine my own Quorn Tool holders and may just copy your idea! Would love to see a Part 2 (or more) where you grind up some tools! Thanks!

Hello John, Fabulous work as normal... a very enjoyable video... Thank you... Take care. Paul,,

Thanks, John! I think I will try ER20 and 5/8 shaft for spiraling tool holder. May go with ER25 and 1” shaft for regular tool holder as I already have a set of ER25 collets (for my mini-mill). Then go with 5C for the large tool holder since I have a very complete set of 5C collets for my lathe (round, square and hex collets).Appreciate your thoughtful reply.

excellent work. That came out great. Thanks for sharing.. Using the Quorn would be greatly appreciated.. Subscribed!

Talk about a great addition...

hi john just recently bought a quorn and wanting to do some improvements the tool holder on mine is 1" diamemeter and i want to put a ER 32 collet chuck on , the one ive seen is 32mm diameter shaft so i would have to reduce the diameter. does it sound feasible to you cheers john

This video came up as a suggestion so of course i had to watch it being a Quorn owner. I bought mine as a failed part build and finished it, most of the castings had been done to a reasonable standard but one thing the builder didnt try was the engraving. As a beginning i made some sticky labels with the markings and i did 0-360 rather than 0 45 0 etc thst the book suggests. When i finally did proper engraving i followed the book, which i then discovered was a bad move. With 0 45 0 you have far too many numbers that are the same which is confusing. Stamping 0 360 there is only one particular number and all but the innumerate will know where they are. Regarding er collets, no doubt by now you have got it all up and running, do you find it inconvenient that you can't remove the collet holder from the Quorn for close inspection of the work?
