Title: Unidentified Roto Mfg Co. Kit
Post by: OilyRascal on April 29, 2012, 06:36:19 AM
My brother has asked for our assistance with identifying what this kit is/was used for.  In researching the company, it appears they are still in business in Fresno and product lines includes mostly things welding; Welding Cable Terminal Lugs, Disconnect Insulators, Welding Electrode Holders, Buship Type Lighting Strings, etc.

My experience with purchasing burners (stoves, heaters, etc.) that are capable of multiple jets .... suggests to me this is a kit of some sorts of fuel jets, but that is a guess on my part.    So if I draw a line between welding and thinking it's a jet of some sort I find myself thinking along the lines of a cutting torch or welding torch, but again that's taking an educated guess and 25 jets is an awful lot of variety for any jet kit in my thinking.

Any insight or assistance (gives Rusty a gentle pat on the shoulder) would very much be appreciated.

The jets look quite similar to carburetor jets for Japanese motorcycles. Old school mechanics would have such an assortment for tuning carbs, especially on multiple cylinder engines. Changing exhaust system or even intake system often required re-jetting.

Carb jets or gas jets for a burner (e.g. a cooker) - not for a welding torch etc.. Although they look a little large for domestic use - industrial gas burner or maybe even an old petrol engined lorry...

They really look like carb jets to me too.

There's a Roto Mfg. in California that makes welding supplies.  www.rotomfg.com

They do resemble motorcycle carb jets.

Look closely at the ones on the top row. I see some markings there. Is one of them the size and the other a stylized K?
Keihin makes carbs for motorcycles.

I will get my hands on them (again) and have a gander.  I didn't take possession of them, only pictures. 

I appreciate all the comments/feedback.
