Shot in the Dark to Find a Tool

[Bryan Boyle]

Figured I'd ask here before bothering a local machinist...but does anyone know where I could score (beg, buy, borrow...) Lotus Tool T.339 as found on page 31 of section L of the Twin Cam supplement?  It's the tool to drive in the throttle spindle seals.  Guess I could bodge something up...but might be nice for once to use a tool meant to do the job I'm trying to do...just sayin.

Bryan, if no one out there has the factory tool to lend out, send me a PM. I have a mini lathe sitting unoccupied. Not that I have nothing else to do, but looking at the drawing specs, it looks fairly simple to replicate. For a professional machine shop, probably less than an hours worth of work. My machinist charges $125/hr, so consider what it would cost you to make the tool. I'm just a novice in machining but it looks simple enough.

With my occasionally used mini lathe, I thought similarly. But if you consider the 8.2 mm reamer as a cost (I don’t have one  ) $125 might not be too out of line. Still, it would be fun to machine.

I recommend seeing what a machine shop will charge for such a simple tool first.

Gong to ping Steve V, since he seems to have touchpoints at machine shops.  I don't know if the 8.2mm is space program critical...only meant to fit over the throttle shaft (if it's in the body...if not...then I don't think it would matter; the seals go on lips out (which means the machining on the end is meant to press the seal onto and then press into the body of the carby, I think...)

Going to suss this out; appreciate your offer, Jojii...

I think a 21/64 drill bit (8.33mm) would be close enough to line it up with the throttle shaft! That's only .005" over ....

Even though we're not building parts for the Mars Orbital Lander, if a tool is available with the right size and not exorbitantly expensive, I prefer using the right tool. A 8.3 mm reamer is about $6-$7 online.  Pretty cheap for a probably one use only tool. Hey Bryan, go ahead and get a quote for the tool. I'll start ordering the material and the reamer to make one for myself. If it turns out usable, I'll mail it off to you. I also need the practice.

That would be great...fwiw, if you were into the r-16 engines...I have the head locator studs and tool, and liner nip block sitting in a box in my garage.

I've fit lots of seals to Strombergs.  It's a simple job.  Use a deep socket that just slips over the spindle.
