Reading the GFI copy I see that they are
not Vessel drivers but drivers patterned after the Vessel design. I stand myself corrected.
The
Vessel impact driver I mentioned is available from a number of places.
I bought
this one from a Honda dealer 50 years ago for $15. But I don't think it has JIS bits. I still have it and should get some bits I know to be JIS. I used it extensively on my 305 Scrambler but never needed it on any of my other bikes. Didn't know then that I should have used a rubber mallet on it and not a hammer.
Ahhhh.....the famous and unsurpassed Vessel Model 250001 impact driver. That truly is one of the best impact drivers every made IMO and as a bonus, I'll bet you dollars-to-doughnuts that those ARE exactly the JIS bits you need for your Hondas, Suzukis, Toyotas etc. etc. I bought one many years ago as well - for around $10 CDN (in the 1970's) and it came with JIS bits.
If you place a want advert on CL or Kijiji - you often find them in OK shape for well under the $93 retail price in the current EBay advert.
I can also report that I corresponded with Paul Jones of
Go Fast Innovations yesterday and here is his message back to me:
Hi Pete,
Thanks for your email.
I expect to have my second generations Gofast Innovations JIS screwdriver sets available in a couple of weeks. Check my website.
I won't be making Impacta style drivers but am working at developing a set of JIS screwdriver bits that will fit current impact drivers.
Thanks,
Paul Jones
Gofast Innovations
As Andrew pointed out above, Paul is a classy guy and provides great products at a great price AND superb customer service. Working on old bikes is fun, but only with the correct tools and so I am really looking forward to getting a set of his new JIS bits for my replaceable bit drivers.
IMPACT DRIVER HINTS: when using an impact driver here are a couple of hints:
- lubricate the internal ramp mechanism inside the driver to ensure that it works smoothly without friction
(you cannot see it because it is inside the body of the driver - but I would suggest giving the thing a squirt of WD40 or light machine oil before use to keep it lubed and rust-free);
-
BEFORE hitting the end of the driver - place the bit end firmly into the head of the screw and then rotate the driver counter-clockwise against the slots in the screw head to "
pre-load" it in the loosening direction - and
THEN hit it one good smack with a mallet.
If you do that - the screw will just about always pop loose right away.
