Re: Is anybody interested in getting together to make some handscrew clamps?
WOW - what a great response! This ought to be a fun event, to say the least.
OK - I'll start gathering information on the kit options, and order some sample kits from different companies for comparison. Thus far, I've discovered that the kits are available from Shop Fox / Grizzly, and Jorgensen, and I've also discovered that a company in Iowa - Dubuque Clamp Works - manufacturers very nice clamps (they still offer the original ACME thread with some of their clamps), and apparently they are the manufacturer of many of the "store brand clamps" sold by some of the major woodworking tool suppliers.
I am in contact with both Dubuque and Jorgensen to see if they would be willing to sell us a gross of hardware. I’m also in contact with our great North Carolina Woodworker supporter Rick DeNardo at the Moulding Source and he is working to get us some good pricing on the Shop Fox kits.
Once we have a good understanding of the quality and pricing options, we can narrow down our selections and see what kind of deal we can make on volume pricing.
At the end of the day, everybody can choose which style of kit (US vs. import) that best fits their needs and budget.
When I receive the kit instructions, I'll post what size blank that they recommend for the various clamp sizes, so that everybody can check their wood inventory to see if they have any material that they want to use for their clamps, of if they want to take advantage of the hickory or anything else that we can come up with.
One thing that we each need to start thinking about is:
1 - What sizes of clamp that we want to head home with?
2 - How many of each size.
Here is some sizing information, courtesy of Jorgensen’s web site:
The first number below is the Jaw overall length
The second number is the maximum opening between Jaws
and the third number is the reach from the middle spindle to end of the jaw
4” 2” 2”
6” 3” 3”
8” 4.5” 4”
10” 6” 5”
12” 8.5” 6”
14” 10” 7”
16” 12” 8”
For a "rough pricing" perspective, use the following budgetary number for the import clamp kits:
4" kit - 2.50 each
6" kit - 2.75 each
8" kit - 3.30 each
10" kit - 3.90 each
12" kit - 4.30 each
For the US mfg kits (Jorgensen hardware), use the following budgetary numbers:
4" kit - 5.60 each
6" kit - 6.60 each
8" kit - 7.50 each
10" kit - 8.30 each
12" kit - 10.50 each
16" kit - 14.00 each
I'm pretty sure that we'll be able to source the clamp kits for less than these numbers, but for budgetary planning I always like to estimate a little high versus too low!
Think about sizes, quantity and import versus US, and in a few days I’ll post a poll and sign up sheet so that we can start compiling some numbers.
Thanks much.
