Stuart D10
« on: June 15, 2015, 10:04:09 AM »
Purchased a partially completed Stuart D10 a couple of weeks ago.

Stripped it down and bagged it all up to see what I needed to do to it.

Left cylinder had been bored but that was it and the right cylinder had been bored and the steam passages drilled. One of these passages had been done quite off centre and quite poorly so it was out with the JB Weld.

The left cylinder has now had the steam passages milled and drilled

I'm not too happy with the holes for mounting to the stand of the right cylinder either. One has broken through. Any suggestions? Or is it time to buy a new casing?

Another question is that the crankshaft looks like it might be manufactured from one piece and the crank pins are set (machined) at about 120 deg rather than 90 deg.

Does anyone else have a D10 like that? Will there be any problems with an offset like that?

Regards

Bruce

BTW does anyone know if you can link to shared google drive images?

Some photos would help if you can

120deg won't help as it won't self start at some crank setting. Unless you are going to make it a 3 cylinder expansion engine...

Trying with the photos but the forum does not like google drive links

That hole doesn't look like it matters much. As you've got DRO's you could make it a 6 hole fixing for the covers with 6 new holes (I don't know the drawings) and as you are chucking the JB weld around you could fill in the old holes. Alternatively John A does a good job with his Mig welder if you get in touch with him

Is the crank glued together with loctite? if so bit of heat and it will come apart and you can re assemble. Use a new bit of silver steel for the main shaft. make it complete and once its all set machine it away between the crank webs

I am pretty sure the crank is one piece. I can not see any different material on the end of the webs

Thanks for the advise Pete

Wack some heat on it and if if falls apart you can re-assemble, otherwise chuck it in the bin and start again. its only 4 disks, three lengths of silver steel and a drop of high strength loctite.

Bruce,

I resently did a build log of a D10 from castings on Modelboatmayhem  (http://www.modelboatmayhem.co.uk/forum/index.php/topic,49574.0.html) which may be of interest to you and can answer some questions on why the stud hole on the bottom of the cylinder casting broke thro'.

I can also mail to you 3- pieces on A4 size of the D10 drawing which you can tape together if you send me your e-mail address via Personal mail, don't put your address on the open forum.

Can you please tell me what JB Weld is as I am not familiar with it.

George.

Thanks George

I have the original drawings too

As Jo indicated JB Weld is an epoxy glue the is temperature resistant up to about 400 deg F (I think)

The D10 is my next engine so I was happy to see that George posted a link to his build log. Is it just me or are his pix not showing on screen?
Best,
Stan

Joe,
Thanks for the link, I didn't know about this epoxy but will get some and try it on any mistakes that I make, I usually use Chemical Metal  which is a Hermitite product that I get from Halfords.

I am sorry guys but I can't help about not seing my pics on M.B.M. of the D10 build, this Forum is for model boaters but as my interest is Marine steam and I have many friends there and to see the pics you may have to join up which is free of charge.  MODELBOATMAYHEM Google it and you will get the details.

As I am not a trained machinist I use this forum for ideas on how to hold and machine , castings various,and have found the forum extremely helpful and friendly , so thanks to all.

Bruce
If you can get into the pics on page 3&4 you will find that I had the same problem with the holes on the cylinder covers which are 1.125" P.C.D.
I drilled for 5- holes but had to plug them and re-drill 4- holes on  1.062" P.C.D.

Over the years Stuart's have used various foundrys and the general agreement is that the cylinder and other castings are cast using an existing casting rather than making new patterns.
I hope this helps.

George.
