D-tubing for centerstands, heavyweight models
« on: 14 Jun 2010 at 02:20 »
I just finished a die to press the D-tubing used by Douglas for centerstands on the 1930s models.



The type made and shown below has a one inch joggle and are a little wider than used on most other Douglas models. In fact the only model I know of at the moment which it will fit are the 1934/35 OW/OW1 models.





I still have to get my trained termites to remove the wood stuffing from the tube.  :)

Most other Dougies used a 3/8 inch joggle, like the S6 and the mid-thirties Aero models such as these original samples shown below.



But the plan is to cut the punch and die down to end up with a tool to press the more common style. Also I knew if I was able to successfully press the one inch offset, I would be able to press the half-inch offset.

So is anyone interested in a 'kit' of one horizontal with joggle and two uprights in 0.060" wall d-tubing? Similar to that shown in the first picture. These are left a little longer than required and you will have to trim these to suit and then fabricate (or repair) your own center stand. All I would be supplying is the d-tubing (the wood will be removed.) The three pieces would be US$15 plus postage. If you want just the horizontal joggle bit for a repair job, it would be US$10 and postage.

If any one wants one with a one inch joggle, speak up quickly as I only intend to make a few extra for other 1934-35 OW/OW1 owners, and then the punch and die will be cut down and there will not be the opportunity to press any more.

That will leave the tool configured to press the half inch joggle, which I assume is what most people will want. I would prefer to setup and do them all in one batch, but the option would remain to drag the tooling out again and make more. Or for someone else to make more as I will have moved on to other projects. It takes about 40 tons to squash the tube nicely. More immediately, I need to know how much tubing to purchase. While I will run a few extra to stock on the shelf, I was not planning on making several dozen on speculation as my experience is the stuff just languishes around forever. And no doubt then gets tossed in the rubbish when you 'kick the bucket' and they settle your estate!

Hi Doug,

Don't know if you remember me from the Centenary Rally? I've been loving seeing some of the work you've been showing us on the forum. I know that young Hamish Gullick needs a stand for his S6 which I'll be happy to grab for him. So count me in for a kit. Another friend might need one too so I'll get back to you about that soon.

Hi Doug,I too love seeing your work and postings.  I only dream of producing such quality products and tooling as you do.

Please count me in on stand components for my S6 project.

I will be in the US in August, by don't think I am coming close enough for a visit.

Regards

The press tool has been modified for the 3/8-inch joggle a few stamped out for immediate requirements and those that have already requested sets. I will see how an advert in the New ConRod goes, and run off the main batch. And that will be that.

On the right are a dozen of the one inch joggle. These should take care of all the surviving OW/OW1 models, plus a few extra. There will be no more. Flanking on either side are the uprights.
