269760 pdoubek@x... 2020‑01‑23 Emmerts Turtleback questions and WTB parts
GRRR!!!! I don't know why my e-mail does this occasionally, and it  
hasn't done it for over a year so I got complacent. It sends the  
subject but drops the body. My apologies... I'm not as dumb as the  
first post would suggest! :) My attempt at a repost never showed up on  
the list, so I'm going to try again... I hope it behaves.

I found an Emmerts pattern maker vise of the Turtleback species on one  
of the local classified listings last week. This is something that  
I've lusted after for 30+ years but they seem to be scarce in Northern  
Utah. I've only seen a couple for sale, and the other was so full of  
cracks, brazing, and bad welding that it wasn't worth the gas I burned  
to drive 40 miles to see it. This one was closer, more complete, and  
damage is minimal. I bought it... I hope I don't regret it! It's a  
Type 5, as defined by mprime's Emmert type study:  
http://www.mprime.com/Emmert/type_study.htm

The only damage I've found so far are 2 bad dogs and the mounting  
bracket/hinge. One large dog was badly broken and welded, one small  
one has some cracks that haven't failed yet. The bracket is in 2  
pieces with a third piece missing, so it's not salvageable.

The tortoise shell was missing a screw, so I threw a shiny replacement  
in there until I can find won with the appropriate patina so as not to  
draw my attention toward the shiny thing. With only 3 screws holding  
it I worry about breakage if it gets bumped hard with only 2 screws.  
It has the tilt adjust clamp but is missing the lock lever so I made  
another shiny thing from a handle I bought at Ace Hardware. It also is  
missing the tilting jaw accessory.

I see a lot of breakage in the online pics of these things and I'm  
curious whether they were poorly manufactured, if they were just used  
hard, or if they mostly get damaged due to their size and the fact  
that many people don't seem to understand how much force is required  
to do a job. (I saw a post where someone suggested replacing  
contractor saw (tailed meat grinder, Jeff) trunnion bolts with grade 8  
so you can really crank them down. I wonder how many table castings  
were destroyed with that suggestion!) It seems that the mounting hinge  
is often broken, but I guess that could mean the ones on the market  
let loose from the bench and crushed the owner's foot rather than  
indicating that they were underbuilt. Mine has some pretty bad looking  
casting on the hub that looks like it came from the factory that way,  
and the fit around the dog holes is pretty bad.

Is there a good source for parts? I might fabricate the mounting hinge  
from steel angle but original would look better (you know... it's all  
about the patina!). With the way the dogs are built I don't know if  
I'm better off fabricating them too, or if they work just fine if you  
don't over extend or put excess pressure on them. I've already made  
the tilt lock handle and it's functional, but an original would be  
nicer or I may remake it to get a little better fit than my first  
effort. Lastly... there's that shiny 5/16-18 pan head screw on the  
tortoise shell.

Here's a link to pics that I didn't have up when I tried to post last  
night: https://imgur.com/gallery/LL07eIf I hope that shares okay...  
it's my first time on Imgur.

TIA and Happy 2020,
