A (purely informational) picture of the Plastic Vise
Added 2020-11-09 14:04:17 +0000 UTCFriends:
There’s been a great deal of interest in the plastic vise. I thought the community would enjoy a more detailed picture. So, I laid the whole thing out on my scanner and took a high-resolution picture. I’ve included an imperial and metric scale and the total image size is standard 8.5x11.
Let’s be super clear here: this product might still be under patent and I have no interest in subverting someone else’s patent (and ending up in court). This picture is presented for informational and entertainment purposes only.
What you do with this image is entirely up to you.
Hope you find it entertaining!

I have restored hand planes for friends for free. Their neighbors saw the work and had me do some for them. I have received many planes for free as gifts for doing this. A lot of the older woodworkers in my area retired and their tools rusting. Their children have no interest and they figure they would give their tools to someone who appreciates and would use them.

2021-02-04 13:24:35 +0000 UTCI think I would use some bench dogs, a couple of boards and some wedges.

2021-01-10 05:33:47 +0000 UTCI started to work on these parts. I found a couple of others that I'll check out and remix into one. https://www.thingiverse.com/thing:4713990. The patent shows a bunch of other parts. a 45, a small stop, screw clamp. I'm also going to include adapters for 13mm and 19mm(3/4).

2021-01-07 19:54:31 +0000 UTCI've been playing around with 3d printing dog hole accessories for my new bench - any possibility you're open to sharing the STL files for this?

2020-11-10 16:42:10 +0000 UTC3d printer matching 19mm(3/4) benchdog technology gets you this https://imgur.com/gallery/s5SONYu I think I prefer my homemade moxon, but the concept is very valid

2020-11-10 07:49:29 +0000 UTCPlastic parts often have the pattent number stamped right on them. Do we have that?
Denise Skidmore
2020-11-10 07:43:17 +0000 UTCThere are plenty of non patented cam designs, and it might make more sense to design your wooden version based on normal bench dog holes that also work for other types of clamping. The dropped pins on the flat side could be actual bench dogs.

2020-11-10 03:54:57 +0000 UTCFYI, Marius Hornberger also came up with a cam clamp system that he uses to hold down things of his CNC. https://youtu.be/O-rqf4uSXRE

2020-11-09 23:30:25 +0000 UTCThanks for the pic. I see where you can use a box end, or socket wrench to crank the locks. That is a nice idea, harder to implement a hex in a wooden replica, but maybe it is worth thinking about how to do that in wood.

2020-11-09 22:20:58 +0000 UTCSo... When we gon make some from scrap plywood?

2020-11-09 18:58:30 +0000 UTCThis looks like something that one could easily fabricate for personal use from some quality plywood and hardwood dowels... Just saying.

2020-11-09 17:13:23 +0000 UTCThere are MANY old books from the 40s and 50s with illustrations of using wedges and posts to clamp work.

2020-11-09 16:43:44 +0000 UTCI like those UJK clamps - very cool - thanks for sharing that!

2020-11-09 15:56:04 +0000 UTCRex, when you came across this hair brained (pun intended) idea for a video, what percentage of your thoughts were telling you to ditch it and find something, anything else? Maybe next week you can find something sponsored by Mr. Ron Popiel? Maybe Ronco did an all-n-one dovetail jig/vacuum cleaner. Honestly, surface clamping is an issue. I have a (read: one) Bench Dog. It works great, however, I'm working on some slightly cupped 5' slabs and I've had to be rather creative to hold them down. Something like this, or at least something that solves the same problem would be awesome. It has me thinking.

2020-11-09 15:19:51 +0000 UTCThe patent office has the patent (US4157819A) as expired. I did not see a renewal or adaptation from the 1977 original. You are probably good. (insert legal disclaimer here)
Joseph Scone
2020-11-09 15:14:15 +0000 UTCwhat about building something similar in wood? If cams are too hard to build we could use wedges and a simple stop..

2020-11-09 15:08:09 +0000 UTCHey Rex....how bout a poor man's diy version that uses existing 3/4 inch dog holes?
Matt Mohon
2020-11-09 14:50:41 +0000 UTCThis will be very helpful. I was planning on using some basic drawing program on my wife's computer to make a template of sorts to print out and glue to some half inch or so thick oak pallet wood and go from there, but this will save me a little time.
The Poor Man
2020-11-09 14:43:15 +0000 UTCThe patent is from 1979 https://patents.google.com/patent/US4157819A/ , so it expired in 1997. There are some nice details in the drawings, this is one of those patents that looks like it does a good job of laying out the invention. Also, the Critt-Vise trademark ran out in 2008 https://trademark.trademarkia.com/crittvise-73625280.html so it's probably safe to use as a generic. I am not a lawyer, this isn't legal advice :-P

2020-11-09 14:36:17 +0000 UTCI was looking for a more detail view of this, Thanks. I find couple on ebay for about $35. They were originally sold at Sear and Roebuck co.
Edgar Orr
2020-11-09 14:33:28 +0000 UTCFrom what I saw on the video, 18 mm or 3/4 inch plywood should be of similar thickness.

2020-11-09 14:14:45 +0000 UTCUnder patent? I don't know I I can be patient for this!
Rebecca Fishlock
2020-11-09 14:05:58 +0000 UTCHow thick are the plastic pieces? I'd find that extremely entertaining, dimensions give me a real chortle
