In this video I show you how I made a set of arbours for my old and unusual surface grinder. This is part 1 of 2, making the arbour body. I hope to finish the process in part 2.
I’ve never seen that chuck before. Can you tell me who manufactured it, and, if you have any idea, which model and possibly even some date? I’m very interested in machine tool history and have a couple of 3 foot shelves of old machine books and a bunch I’ve downloaded as pdfs. In all of that, UK and USA based books, I’ve never seen that chuck.
Yes Sir, got a db200 and a little proxxon xy table. Genuine proxxon. Nice little piece but anyway thinking about making one with them as have the new h old stock parts with db200, arbor, few grinding stones, everything but little milling table for the lathe. So that's y going use proxxon xy table. Thanks for sharing the video I really appreciate it and enjoyed it.from ur ole hillbilly buddy.stay safe.
eyup Paul Very interesting, and a great job, As for the tip at the end, i was just mumbling to mysel, like i always do!!!, i add coolant whilst doing that, then you stole my thunder at the death!!!! ah well!!🤣🤣😉😉👍👍👍👍👍👍 see you next time ATB Kev
Hi Paul ! Do you need a Balancing system for this small grinding disks? Years ago , I worked with a 450mm Diameter disk on a 50years old " TOS " round grinding maschine. This one had exaktly the same System only in big 😅 greetings from 🇦🇹 .... Part 2.... Missed 😉
Hi, in the past I have worked a 6metre Erfurt with a 750mm x 120mm wheel. I would not like to use that without balancing it. It would be like a bench grinder straight out of the box. Whatever size the wheel, it can be used without balancing but, you run the risk of the wheel becoming unstable and cracking not to mention the finish being poor. one other thing a balanced wheel also cuts much better and lasts much longer. Regards.
Hi Shed. The tip very usefully will employ it when cutting a larger profile. I need to also make some arbor for my old grinder that I'm giving new life to. Await next installment
This is excellent timing Paul, I've been putting off making some wheel flanges. I was thinking of using a dovetail cutter on the rotary table for the balancing slot. However having seen your video I prefer the idea of a profile tool in the lathe. One observation, I have a camlock chuck on my Colchester so I can run the lathe backwards after the outer cut and move the toolpost to the far side of the job, I can then cut the inner taper on the same setup. Is there no way of locking your screw on chuck in place to prevent it undoing in reverse?
Hi, thanks, there is no known cure for reversing the chuck on the SB at the moment without changing the spindle. mind you I have got an idea that might work, but I have got so much to do at the moment that I haven’t much time to get videos out, but watch this space. Cheers
Interesting project, look forward to the conclusion. Some folks blame the table drive method for a rippled finish, is your's a rack and pinion? I'm unhappy about the table oiling (lack of) system and bought some ceramic lube to try when the grinder comes out of hibernation in a month or two. I might make up a cable drive for the table to eliminate any cogging from the rack if the oiling doesn't help with finish.
Hi, mine is a helical rack and pinion. The cable system is probably the best system in my mind, no backlash. My grinder dosen't have slides or rollers. My table sits on a horesontaly opposed double vee plate and roller bearings on each side with vee grooves in them. It is so smooth, silk dosen’t even begin to describe how easily it moves. And the bearings are sealed, no grease required, with this system hidden underneath it bearly gets dusty. Regards
Brilliant video Paul ! Really enjoyed it. The tip at the end will get tried out soon. You know how I like to chatter 😮 Say hi to Mrs. SD for me. All the best Neil....

I have an earlier Eagle surface grinder and never had a problem with abrasive wheel imbalance apart that is when I have used cheap imported wheels. I bite the bullet and now only use Norton SG wheels. My Eagle has no dovetailed balance weights and yet my Chinese surface grinder does have an arbor with dovetailed balance weights. I remade the weights in brass to give them a tad more mass.
@@Thesheddweller they are only tiny weights so the brass made it possible to dial out the imbalance of the horrible imported abrasive wheels. I have heavily modified the Warco surface grinder but you can only polish a turd so much you know 😂 The Warco is less tiring to use though so I alternate work between it and the Eagle.
@@shaunchurchill4594 you’re right turds are a real pig to get a shine. I nearly bought a Warco grinder, and as you only get what you pay for, well….. mind you my little lathe has always done its job, after a good polish that is. Regards.
Hi Paul, I like your thinking. I too have an Eagle waiting for restoration, the hubs would make it much more versatile if I can ever get my head around the direction of wheel rotation which is opposite to my other grinder and the venerable J&S 540.
I have one too but the wheels fit directly to the shaft, I would have to find wheels with a bigger bore to be able to fit a balancerable adapter. Does the lack of oiling points bug you too?
Mine under a tarp outside so I haven’t got into it yet apart from a quick run up. Most wheels are as Paul said 32mm bore and if I recall correctly Paul said the shaft is 25mm so that gives him 3.5mm wall thickness on the arbor. I haven’t noticed the lack of oiling points but I did think on someone’s restoration I saw that the arrangement of oil grooves could be improved, or it might have been a lack of them. I the other are missing I’ll definitely be adding them.
@@tonyray91 strange coincidence, mine is under a tarp in the front garden too. The shaft on mine is 1 1/4" so the wheels fit without any addition. I would have to find wheels with a larger bore to fit any balancer.
That is indeed strange. My friend also has one , he, he’s never mentioned a reduced dia.shaft but I do know the wheels are direct mounted.. Paul’s machine is a let model I think as it’s direct drive wh raise mines belt driven. I’d be tempted to make a new shaft with a taper the same as my Harbots SG and with a LH thread so I can run it the ‘right’ way round.
Hi, thanks, yes it looks like burnishing but it is peeling the swarf off, if you get it right, and it does take a bit of practice,.. the finish is wonderful. I used to finish 15mm deep x 12.5 degree dovetails this way under power at 0.4 rpm… I always got that job and the bounus on that job was easy money. Cheers
Thanks for sharing Paul. Takes me back to when I made an adapter to use my surface grinder wheel flanges on my tool and cutter grinder, and made a few wheel flanges since I couldn’t find any to buy. Trepanning that groove for the weights made me nervous when I did it but it went well for me also.
That was as excellent as always Paul, thank you. I don't understand how the dovetail peripheral slot will be used for balancing but I am sure all will be revealed.
Diddly Squat is both imperial & metric. 😁👍🏻👍🏻
Agreed. Diddly squat also applies to my imperial and metric adjustable spanners. 😁🤣
Nice. The lathe could handle these big trepanning cuts very well.
And indeed a very useful tip at the end.
Thanks Michele, cheers

I am waiting for the followup to see how the balance is achieved!
So am I. 😅

Hello Nell, still a bit cold in your shed? Mrs SD said hi… cheers buddy
@@Thesheddweller I got the hint 😊😊😊
Great video Paul! I'm still searching for a surface grinder, no luck thus far.
They are just like busses, you wait for ages for one to turn up then several turn up at once….cheers
