Hold Down Clamp Build // Wood Lamination 101
HTML-код
- Опубликовано: 14 авг 2024
- Let's face it, if you're going to use t-tracks, if you're going to make jigs, you're going to, at times, need to hold things down. A hold down clamp does just that: it holds things down. In order to get pressure to hold things down, we need a little bit of spring. We can create that spring with a hold down clamp made from laminating wood. Don't worry, this is an easy thing to do, so long as you have the right kind of mold or form to do it. In this video, we're going to go over the steps needed to make a very basic hold down clamp out of oak and walnut. Check out the website for an indexed step by step as well as materials and tools used. This is going to be a fun one!

Great RUclips Video ! Thanks .
Functional and beautiful. I'm adding them to my build llist
Strange how 'handmade' means 'craftsmanship' but 'homemade', for most people anyway, means 'cheap and shoddy.' I like both and neither can be churned out by mass production. Cheers Rob.
Brilliant, Rob! I'm definitely going to try it! 😃
Stay safe there with your family! 🖖😊
1:14 what you need between the two pieces of walnut is a spacer... what about a scrap of t-track? That glue doesn't stick to metal right? Or even wood wrapped in packing tape as a spacer? 💖🌞🌵😷
Rob, this clamp is ingenious. You pointed out voids between the lamination in the curved region. I think the voids are being caused by the radius of the inner piece being the same as the outer piece. This means there is less clamping pressure in the curved region. I will email you a PDF file of a drawing with true tangents between the curve and straight lines and a reduced radius on the inner piece. You can share the file with your viewers if you want.
The grittiness of the salt is a great idea, but you've got to work fast as it dissolves into the moisture of the glue making a tight bond. Once dissolved you've got the same slippery mess as without the salt 💖🌞🌵😷
Use sand, maybe? It surely will not dissolve in the glue. However, most glues are not so watery that placing some grains of salt will dissolve fast. You should have plenty of time to set the boards together without slippage.
The only reason l commented was that it seems like the wood was slipping here 1:22 and it could be because filming takes a few minutes. You could use very fine sand but l thought this glue wouldn't fill gaps that sand would probably make... forming a weaker bond. The dissolving of the salt eliminates this problem. Sending lots of love 💖🌞 from sunny 🌵 Arizona 😷 1:31
BTW, Rob, look for some "sticky battery pads"... They're used to help to hold the battery in place on quadcopters. They're REALLY sticky, they get dirty, but a wet rag solves it and it gets sticky again. And they're self adhesive...
I have some here and I guess I should try it! Who knows, right?
BTW, there's the thicker and the thinner stuff. I have the thicker, but I don't know which would be better...
Very cool idea, thanks got the inspiration as always. Stay safe
I like the how to, and yes I will be making some in the future ❤
Using the thin saw blade is probably a better idea than the bandsaw for this. I'll have to try this since I feel like I could always use like 2 more of these hold downs
