All,

I am looking for a snapshot of the pin which fits inside of an Eldi chain tool.

Anybody? I've looked all over the WWW. Plenty of photos of the tool, but none of the small pin which drives out the chain pin.

Thanks in advance,

Kurt

Hi Kurt.

Have looked high and low for an ELDI catalogue but have never found one.

If you get some information please post!

Here's a picture of one. The extractor pin has snapped off, but it shows you the configuration, with a central flange having a mounting pin on one end and the extractor pin on the other, which is fairly standard. The central flange measures 0.312" diameter x 0.125". Mounting pin section measures 0.164" diameter x 0.505".

Progress -

checked me files and found an ELDI print catalogue dated 1973

tool is Nr. 49

replacement pin is Nr. 49A

replacement pin listing is text only, no illustration

Sorry for bringing back this older thread but it is exactly my subject.

I have this exact chain breaker. I'm sure I bought it in the 1970's when I briefly raced.

I am looking for replacement pins for it and I am having trouble finding them. Is this Eldi CB too obsolete?

Eldi may be one of the venerable brands of back in the day but they are a bit crude no matter how you cut it.

Very long screw for a bicycle chain tool, any slack in it creates deflection and binding when extended.

This was probably a multi use tool for motorcycles too and everything in between, easily loosing its precision needed for small chains.

You might be able to find a grade 8 screw to use or you could have a pin made but my view would be to display it for its place in history.

Merziac, thanks for the reply! I'm thinking I might be better off just buying a new, modern chain breaker.

If anybody has recommendations I'll listen!

To repair an older tool you need or just happen to like, check Brownell's catalog. Yeah, they're a gunsmith's company, but some of the tools are very similar. Brownell's has the makings for hardened pins, including instructions for heat treating raw stock from pins to springs. I've done that years ago and it was easier than I'd expected and an instructive experience. At the time I had a rural home on three acres so I used my existing garden burn pile to make a pit for heat treating and hardening using traditional methods for blacksmiths and gunsmiths to fix or make new springs, pins, etc.

My chain tools include a shop grade tool that came with a Venzo tool kit from Amazon (alas, since discontinued). The Venzo kit was better -- less expensive with better tools -- than the comparable Nashbar branded kits that were popular before Nashbar was sold a couple of years ago.

Another tool I often use came with my Spin Doctor Rescue 16 multi-tool. Good small chain tool and excellent spoke wrench - I prefer it to the spoke wrench that came with my Venzo kit. Clever design. The spoke wrench serves as the wingnut handle for the chain tool. It spins off completely to use as a spoke wrench. It's a great value at $20 and a bargain for the $14 I paid at Nashbar during their closeout/blowout sales a couple of years ago before the corporate transfer. Only quirk is it doesn't fold completely flat.

The HeroKit multi-tool is similarly designed, *does* fold flat (fits in my minimalist Lezyne Road Caddy seat bag), and seems well made. I haven't used the chain tool or spoke wrench yet, but have used the various other tools and they all work fine.

Between the two for the same price -- $20 -- if conserving space isn't as important as function go for the Spin Doctor Rescue 16.
