Thanks John. Here's a rendering of the straight version for the reversed linings if anyone wants to see it.

Hi John,

They look great, will replacement surgical rubber bands be available for these?

Doh...I get it, you would just cut your own from surgical tubing, what diameter?

Cheers

John, I will take a set of 50 regular kerfing clamps. Paypal will be on the way shortly.

Quick question John. What is opening size when the clamp faces are parallel?
I laminate my sides and it just occurred to me that with that extra width I
might run into a problem with the clamps pinching at the top and not
closing down evenly on the lining. I might have to make my linings a bit
narrower, and that's fine. Just wondering.

Cheers,
-Dave

John, I have the same question as Dave.

John, will you make the 1/4" clamps available as a separate item? I'm thinking about 50 clamps, but would also want 10 of the 1/4" to do cutaways.

Or, can you make up a set of 50big + 10small and give a package price?

Thanks!

Dennis

Right now, as drawn, the opening is 3/8". It's not too late to change that, however, if there's a better way for everybody.

The little guys will go for the same price since the real cost is in the cutting, de-burring, and anodizing which is charged per piece. So figure $120 for 50 big guys and 10 little guys.

Thanks,

John

Nice looking John. I like what you've been doing lately...lots of great ideas that you're taking risk on to try to bring stuff to the table for us. Very nice...
I too would be interested in knowing what the optimal thickness of the side/kerfing combination for maximum even/parallel pressure. How much pressure do these things put on it compared to small clamps avaliable today? I've been using the 1" clamps available at Home Depot and find that the clamping pressure is right, but it's concentrated in on point, and they're too wide, obviously for curved surfaces.
What are the basic dimensions of these cool things???

Keep the drawing John! 3/8" opening is dead on perfect for my needs.

Don, as I understand it, the clamping faces are 1/2" wide, 5/8" long, and
parallel at 3/8" apart.

Hey John,

Ya just been PP'ed for 50 big and 10 small to suit flat kerfing.

Also, just a thought, if it is no more of a hassle for you, it may be a good idea to have the large and small clamps anodised a different colour, say red and blue. It sure would make em easier to distinguish from one and other when your digging through your kerfing clamp container.

Cheers

Hey folks,

Remember these??



John's work is first class all the way, so if you think you can use some of these kerfing clamps jump in while you have the opportunity to pick these up at a great price. If they are anywhere near the quality of his fret cauls you will not be disappointed.

Cheers

Kim

Good idea about the colors, Kim, and thanks for the endorsement. Nice holder!

Oh yeah, the 1/4" ones can be ordered as a set by themselves as well. I've gotten a couple of inquiries about that.

John,

Thinking about pulling the trigger on your clamps since I'm using the Home Depot & Lowes ones now. The Lowes ones have black plastic covers on the tips that leave stains on the wood, which leaves something to be desired! The orange tipped HD ones seem OK...

I did run across a Pic of the Taylor type, so I thought I would post a Pic for comparison (courtesy of Collings). Yours are much nicer...




Rich

John...

I paypaled your acct $120.00 for 50 & 10...Thank you!

Ok, I'll take 50 of them for $100, as long as they're anodized blue like the picture. I like blue!


I'll PayPal you John...

Oh! I'd like them for the reversed kerf linings please.Don Williams38929.7767476852

John:

Argh...now WHAT am I going to do with all the clothespins I just made up???? :-)

OK, I'll do the 50 + 10 for $120 for the reversed kerf linings.

John, I'm unclear about the advantage of having flat-faced clamps that are parallel at one specific opening width (I'm thinking of the reversed kerf type here). If one varies the thickness of one's sides, or sometimes adds laminations to the sides, it seems that one would often end up with a clamp that is pinching at the top or bottom of the lining.

Am I missing something here? I would think that jaws with somewhat rounded faces (or ability to swivel, or some other mechanism that keeps them parallel at any width of opening) would be the ticket.

Todd, that was my original thought, which was why I asked about what the opening was designed for as far width when the sides are parallel.

Curved faces...not a bad idea actually Todd.

Hey John,

Just pay pal'ed you $220. I would like 100 straight and 20 small, I hope the math is correct with the free 10 with an order of 100. My current build has triangular shaped linings that I made and I do have more of that stock milled but I am thinking of going reversed and if I don't I think that I can make up a bunch of little wedges that I can silicone onto the straight clamps. I like to keep the options open which I can't do with tapered clamps.....I only say this as others may be struggling with which set to order. Like Kim (and others) I absolutely love the fret caul and holder set that you made.

Good to see ya back Shane, make sure to check what i've done with the awesome wood i purchased from ya in January!

Hey Serge,

I did walk through your thread a couple of days ago and was thrilled to see your progress!! I have been way too busy in the past few weeks and need to start to clean up loose ends and get back to a more relaxed lifestyle but I am a few more weeks away from that just yet. I am right in the process of framing in my small 350 sq ft guitarmaking studio and have about 300 sets of spruce to cut to fill back orders....so hair straight back for a while yet. I will post some pictures and the end of the harvesting thread soon. Hey that Hesh, what a guy eh!

Talk to you soon my friend

Shane

Hey amigo, take a chaireh and have a breako Man! Relax for 5 and look at my finished geetar!

Talk to ya soon buddy!

Todd, my thinking was that the clamps would designed for the widest opening anyone would want. For clamping smaller thicknesses, you could just run a piece of scrap purfling or binding around the outside.   The curved piece is an appealing alternative, but I don't think it would clamp as effectively as the flat one when everything is parallel.

Moving parts such as a swivel are out of the question because of expense. Even adding $.25 to each one becomes a heck of a lot of up front money because we have to make thousands of these to meet the minimum order.

To put it in perspective, I'm planning on 3 people working for a solid week to put the tension bands on them. It's a lot of clamps.

Besides, the extrusion dies are already in production.
