Pendant DBP Mandrel

[Mike Stephens]

I just ordered Richards DBP and wanted to know from the creekers out there using it. Which bottle stopper mandrel?

I have 1 drill chuck. I also have spigot jaws for my OW chuck.

Thanks,
Mike

I use the mandrel from Ruth Niles

It's nice in that the threads are cut in a way that they also act as a tap for bottle stoppers.

[Alan Zenreich]

I forgot to mention that the mandrel has a threaded hole that accepts a drawbar... a good thing for offset turning.

[Mike Stephens]

Thanks Alan.

I'm thinking about ordering the $9.00 mandrel from Arizona Silhouette. I would use it with a #2mt collet from little machine shop. Can someone tell me the diameter of the shaft on the mandrel?:confused:

[Bernie Weishapl]

I also have Ruth Niles bottle stopper mandrel. I have the draw bar made up and love it. Like was said the threads on the mandrel cut threads in the wood or acrylic. I had the $9 one from AS and didn't care for it.

[Scott Lux]

I use the stopper mandrel from Penn State. Works a treat.

[Paul Douglass]

I have three different ones, a AS one, PSI and Ruth's. Ruth's is the most expensive, I just recieved it a little while ago, but I like it best.

[Jim Sebring]

I use one from CSUSA in a Jacobs chuck from HF with a drawbar. The shaft diameter is 1/2".

[Mike Stephens]

I got the baker plate and went with the Ruth Niles mandrel.

The Mandrel came today but I have a problem. My baker plate does not screw on all the way. The diameter of the stud on the mandrel flares out at the end.

Are all of you using the RN mandrel using a bushing with it?

[Paul Douglass]

Well I may have miss lead a little in my post. I have three bottle stopper mandrels as I stated. I ordered one of Ruth's because I couldn't find the other two and I'd been looking for an excuse to get it. Guess where I just remembered my AS mandrel is..... screwed into my pendent mandrel! I wonder is my PSI one is screwed into something else I was making?? Anyway, I don't see why you couldn't use a washer as a spacer on the Ruth mandrel. The AS one has essentially a "washer" on it that slips on and off.

[Alan Zenreich]

Mine screw all the way on to the mandrel.

If the stud flares out, it might be a simple matter of touching a file to it while it's spinning on the lathe to true it up.

Why don't you give Ruth a call... she uses hers with the backer plate and should be able to advise.

I would take a look at mine, but both are currently occupied with bottle stoppers in progress.

[Barry Elder]

Please excuse my ignorance, but what is a DBP Mandrel?

[Mike Stephens]

Thanks Alan.

I thought of filing or scraping the mandrel wile running the lathe. Also I thought about counter sinking the mandrel a bit more.

To tell you the truth I would rather not have to alter either.

I will contact Ruth.

Barry the DBP stands for deluxe baker plate. You need a bottle stopper mandrel to turn it on your lathe. Do a search for pendants.

Mack I tried that first. I put a couple different pieces of 3/8" 16tpi threaded bolts and rod in my spigot jaws and just could not get it to run true.

I fixed the RN mandrel with a 1/16" parting tool.

Thanks SOL,

I use the mandrel from Arizona Silhoutte held in a jacobs chuck. I've not had any trouble with that arrangement.

[Alan Zenreich]

Glad to see you got the mandrel tweaked... takes less time to fix it than to make a phone call <s>

[Alan Zenreich]

It's probably worth giving Ruth a call anyway, let her know what you wound up doing... so she can check the mandrels in stock to make sure yours was unusual. Ruth is a lovely lady, she'd be happy to talk with you about it.

[Jon Lanier]

Going to try to get in the shop and turn some pendents tomorrow. Not sure how long I'll last though. Expecting 100+ degree heat.

[Paul Douglass]

Must be hot there, the owl in you avatar looks like he is starting to melt.

[Ted Calver]

I had the same problem with Ruth's mandrel. I just slipped a washer on as a spacer as suggested by Paul. Works great.

I bought the mandrel for the baker plate because I wanted a precision machined tool. If I where to put a 5 cent stamped washer on it, well then I could have just bought a 3/8" 16tpi bolt from the hardware store.

I know. I initially felt the same way, but Ruth's mandrel was actually designed as a bottle stopper mandrel and works great for that purpose without any mods. Using it for pendants is a secondary use so I cut her a lot of slack :)

[Mike Stephens]

I am not blaming Ruth at all. I did not intend for it to come across like that. I had just read that a lot of people use her mandrel with the baker. Alan stated that his screwed on all the way. You are right that it is intended to be used with bottle stoppers.

Anyway I made the mode and it works great. There is no doubt that it is a fantastic bottle stopper mandrel.

[Alan Zenreich]

Mike,

I just checked both of my mandrels, and it turns out that there is a very slight outturn at the bottom of the threaded section on each of them.

I had not noticed this before, and it appears that it does keep the backer plate from seating against the shoulder of the mandrel by a few thousanths of an inch. The distance was so small I had not noticed it, and it didn't affect the performance of the backer plate.

However I will use the same technique that you used to trim off the outturn so it seats snugly.

I agree that this was not the intent of the mandrel's design, and I started using this combination before Ruth started selling the backer plate. So I'll call Ruth and suggest that future machinings of the mandrel be retooled to remove the small outturn.

I use a jacobs chuck and a cut off 3/8 bolt, runs absolute true, what more is needed.

Thanks Alan for checking. Mine was off the baker plate a good 32nd of an inch. It runs great now.

Wally I first tried it with a couple different bolts chucked in the spigot jaws of my OW scroll chuck. It just would not run true for me. I did not try it in my jacobs chuck because I only have 1 and need it for drilling the pendants.

Thanks for posting.
