Burdett 70 Mk2 Surface Grinder

[Me.Participant @me1]

I have taken the plunge and added a surface grinder to my workshop.

Its a Burdett 70 Mk2 in fairly good condition.

Looking for a fellow member who may have or know of others with the same Surface grinder to help swap tech and maintenance info.

Any advice gratefully received.

Never seen one myself, but there’s a bit on Tony’s site

see also for lots of general useful info; note this link is Page 2, there’s a Page 1 as well

Thanks for your response – I have ordered the manual from Lathes.co.uk I’m sure it will have everything i need in it, but its always good to talk to fellow users.

 

If anyone knows of a member with a similar grinder it would be nice to get in contact with them.

I hope the manual you get is useful. The one I got for my Centec was not cheap.being largely old advertising material and whilst on good paper was not much help. Noel.

I hope so to – its a bit of a gamble when you can’t actually see what your buying from these sites –

 

I’ll be sending it back if its not a proper manual……

I spoke too soon – Looks like i will be sending it back –  LOL – they sent me the wrong manual, I ordered the MK2 version and they sent the MK1 manual….

Happy to inform (those of whom are interested) that the Burdett is alive….. The strip and rebuild took way too long only a few small things to sort and It will be fully working again. I will post some pictures once its fully completed.

I now have the issue of making a spindle adapter to balance the wheels – How do I work out what the taper is so I can make the adapter – I can’t take the spindle out of the head.

I think what i’m asking is – how do I measure the taper on the head so I can cut a matching taper onto a shaft on my lathe ?

Do you have a wheel arbor with the machine?
If so, find a couple of bearing balls that are close to the maximum and minimum diameters. Put them in the arbor and measure their distance from the top with a depth micrometer ( or caliper, at need). correct for half the diameter of the balls to get centre distance, then the taper per side is tan⁻¹(((dia1-dia2)/2)/difference-in depth-between-centrelines)

You can use the same calculation, with a bit more fiddling and swearing, by using rings with a known bore on the spindle.

For a perfect fit, once you’ve turned up a female taper, use spotting blue to see how good the fit is and minutely adjust the angle to suit.

Good luck 🙂

PS:- the grinder looks as if it’s got the best bits of the B&S No2 and the Jones&Shipman 540 combined.

Hi Mark

Yes I have the wheel arbour – and will try as suggested. But balls of that size i have not (?).

But you have given me some ideas on how to work out the taper…

Thanks.

Its a beast of an machine and fully working will very much suit my amateur needs – I only brought it because it was there and more importantly …. it was cheap…. Ive spent less tat £200 on parts and paint – and that includes 20 litres of hydraulic oil –  the bed ways still show small signs of the original scrapping so would assume well within their tolerances’…. can’t wait to make some sparks.
