Dumbirons question

[Jay Call]

As I continue to work on restoring Pitiful Percy's chassis, I have encountered welded-on dumbirons. Is this correct? If so, why the rivet (cotter?) through the top of the iron and into the frame; ditto the bolt through the frame and into the little "wing" that lays against the inside of the frame rail? Anybody know? The welding looks pretty rough, so I'm wondering if it was a "fix" from some problem encountered by a PO. Thanks for any help.

Dear Jay, Happy to see you after months on t-abc. As far as I know there is no welding done to hold the dumbiron to the chassis "U" profile. It is held only by rivets. Here damage can occur only by an accident hit. May be the PO want to repair that in an easy way. Riveting need more time and different tools than welding. In the left side you must be able to see the chassis number punched. Some experts may give you correct advise Best regards Madhu -----Urspr ngliche Nachricht----- Von: mg-tabc@yahoogroups.com [mailto:mg-tabc@yahoogroups.com]Im Auftrag von Jay Call Gesendet: Samstag, 2.

Hello Jay, Seems like a bodge by the PO to me. The only rivets in the dumb irons are holding the second cross-member /radiator mount on. Sometimes an additional plate is welded on to the inside of the channel from just ahead of said cross-member to produce a box section a la Mike Sherrell.

Jay I had to replace the dumb irons on my chassis - one had broken at the point the little 'wing' joins the main iron. Also both were in pretty bad shape - worn spring bolt holes. I bought new ones from Naylors (UK) - not cheap but essential. The dumb irons were not welded but as you say were fitted by a rivet thro the top and a 5/16 BSF bolt thro the little 'wing'. I'd check them very carefully for any cracks and replace them if you can get new ones. Regards Chris Howard TC/9164

Jay, My dumb irons are welded exactly as you describe. Hmmm, I wonder if TC's that were damaged, and had the dumb irons replaced/repaired, routinely had them welded as an added strengthening measure. _Peter

To all of you who provided a response to my question about Percy's welded dumbirons, thanks so much. The consensus was: 1. The dumbirons were not originally welded, but held in place by a rivet and a bolt through the little "wing" or "tab" that runs inside the frame rail; 2. The dumbirons on our old cars were often welded by PO's; 3. Unless the front-spring retaining bolt is stripped, just grind the excess weld off, make sure the rivet and bolt are secure, and leave it alone. I intend to follow this sage advice.
