Thread: Dore Westbury Mk2 drive pulley repair
17/11/2017 11:14:22

Finally cut my first chips with the mill :D

Very nifty Ian, thanks for sharing that one :D

I like the idea but I don't have taps and bolts that big which is why I used my lathe
13/09/2017 23:56:44

She's nearly there guys, I can almost smell the cutting oil...

 

The lower pulley section is back on the mill now and runs very smoothly

 

Needed to find a reamer I could use with the limited equipment I have, which held up precedings for a bit. Luckily I managed to score a precision 1" chucking reamer on ebay last week that had only been used once, so I was still nice and sharp and didn't mar the brass.

 

I'm now making a holder for the drive sleeve. Though not seen, it has a 12mm shank which will be held by a 2MT collet in the tailstock.

 

Not much left to do now...

I got the drive sleeve bushing out, but because of the shoulder, I used my lathe to thin the brass enough for me to pull it out with pliers:

Thanks Micheal

I went ahead with the vacuum chamber to prime the oilite bushings, and it worked a treat

19/08/2017 00:37:52

It transpires I have a Mk1, apparently distinguishable by which side of the machine the quills fine feed is (mine is on the left, Mk2s are on the right).

The inner drive sleeve (thanks for dropping the correct name for it John) and small clusters still need a good clean , which I can do now they're appart, Ill probably get a better idea of what's what then.

Finally gathered all the necessities and got my degassing chamber down from the loft, which I'll be using to prime the oilite bushings.

After having at it, I finally got the planetary section disassembled but may have hit a snag.

It might just be me but it kinda looks like the bushing butted up to a shoulder, can anyone confirm that?

If it is, any ideas on how to remove the bushing?

If I turn my press bar down to fit the bore from this side, it won't be wide enough to catch the bushing on it's way through. Annoyingly it fits just right if pushed in from the gear side.

Hi folks

Ergh, gathering everything I need is taking ages on such a small budget, but I'm nearly there.

Bushings are in (got two sets just in case), as well as the circlip pliers. Just wating for the oil to arrive, and for me to get an apropriate piece of bar to use on them. Last months budget went on a desperately needed metal band saw, having been donated quite a bit of stock materials, it was starting to become like the saying "water water everywhere, but not a drop to drink" lol.

I made small progress with the lower pulley section, though I didn't need a bar, it was so thin on the one side I was able to prise is out. Judging by how stress resistant it was when bending it, I don't think it was an oilite. Since wear can hide and fill the gaps of an oilite, I snapped a piece off along the thickest area to see if there was any evidence of holes or pockets running through the fracture:

As can be seen, it appears to be solid so I'm guessing the other one will be too.

Regarding oil preload. I've seen people use hands and whatnot to press oil throughout a bushing, but was wondering, would using my vacuum chamber work?

I made one for moulding/casting resins and silicone but it occured to me that it might draw out the air and fill the bushings that way, I could warm them up a bit in the oil to aid the process and leave them to cool in the vacuum.

Canobi,

Just checked my DW spindle and I find that any of my morse taper tooling which all measure around 2.5" long fit my spindle without any problems. I do wonder if your spindle nose may have been modified (shortened) at some time in the past. I machined my spindle when I built the machine to the D/W drawings to suit the Myford spindle thread. Mine measures including the shoulder with the spanner flats 1.5".

Thanks for checking Pillip, I was wondering the same thing, the pulley only has a stack of three as opposed to six I've seen on most and the quill thread, while 1.125" x 8tpi is Witworth, not UNF.

Quick update and a thank you to Mike again.

Ashley Power were very helpful and I have two sets of correctly sized bushings on their way to me for a very reasonable price

I also picked up a set of circlip pliers and will get stuck into tearing the pulley down when the bushings arrive.


I have a question to all DW owners, I removed the Jakobs chuck that came with the mill and found the morse shank had been shortened and retapped.

Measurement of bore depth came to 2.1/4" and regular length shank are too long,Is this normal, or something specific to my mill?

The way I see it I have two choices, take the quill out and re-bore it, or modify any MT2 arbours I want to use in the mill.

Not as keen on attempting the former myself using such an old lathe but the latter would be in the realms of doable.

Canyon can you let me have your contact details please, I have a Grayson and may want to ask some questions about it.

Thank you,

Ian

When I rebuilt my DW some years ago I replaced all the oilite bushes, and I sourced correctly sized parts at very reasonable prices from Ashley Power in Poole. Website at www.ashleypower.co.uk. They don't seem to list imperial sizes in their online store, but you can order them by phone.or email.

Hth

Mike

That's awesome, thank you so much :D

23/05/2017 13:05:56

This is all great info guys, Thanks

I found a perfect oilite for the base which is 1" x 1.1/8" x 1" bore, but no 2" with the same ID/OD. There's one with a 1.1/4" so may get that one and skim it to size if I can't find an exact match.

Not sure about old though, she's a whippersnapper next to my 1930s flat belt Grayson lathe ♡

Runout was an astonishing 1.4mm when I got her, managed to whittle it down to .1mm (.003 inch), Not bad for a total beginner and an old lathe.

Yep, right icon but I should have been using a direct link which I'm not used to using.

Here she is from the other side

Tony Pratt, here are the images in the order Canyon Wren posted them. You don't need a photobucket account, it was just the links that were not correctly inserted in the post.

 

I would love to know how you did that, can't seem to make it work my end.
