Excellent Holdfast Clamps made from screws

I made a Holdfasts clamp using a screw and a square pipe.
Very easy to use and can be fixed firmly.

Brilliantly simple, Gregor's idea of shrink tube over the threaded post is spot on, that'll make it work well even for benches made of soft wood

[@betteramwthanbmw]

@ EngineerMike F: I occasionally use sections of used, replaced bicycle inner tubes (they come in various diameters) as a protective lining, as well as heat-shrink tubing, but in vulcanized natural rubber it's inherently softer. And you can usually get them for free in bike repair shops if you don't ride a bike yourself. Here maybe the tube of a racing bike for the threaded rod and for the clamps Pieces of a touring bike inner tube.

@@trinitytoo but what are the parts to make the screw down

[@jisakukobo]

@Mama C I think that the size should be made easy to use according to the workbench to be used. I didn't include the dimensions because I didn't think the size was important. The point to note is that I do not use aluminum materials. All made of iron.

[@carlossimoescampos1]

Trinity, thank you very much for ypur information. I've already noticed about this, but it is missing from JSK-koubou the measures of the "square guide".

[@andydukelow4560]

This is a great idea! In regards to the threaded rod wearing out the holes in the hardwood bench, I don't think an average user would go through enough clamp cycles in a lifetime to do that.

[@alfredomarquez9777]

Specially if the user takes a bit from the very edge of the thread... simple wet or dry sandpaper will easily kill the very edge, leaving enough to hold the wood of the bench, but lessening any pronounced wear of that wood!

Maybe try putting heat shrink tube over M20 thread, the one electricans use, to less damage the hole in the bench?

[@jisakukobo]

your idea is good I'll give it a try.

[@andrewbieger5004]

Great idea.

[@pdloder]

The thread gives extra purchase - cover the thread and lose holding power. At least by my reckoning.

Coat the bench threads with epoxy to fill them in. Then spin and sand in the drill press. That way you don't enlarge the diameter with shrink tubing or a sleeve.

[@Phazaar]

The threads will eat up your worktop - for those with a 3D printer, it's really easy to use a slightly smaller screw (saves money too) and 3D print a threaded tube to slot over it. This lets you dial in the size for your worktop, protects the edge, and still has all the strength thanks to the screw.

Brilliant, only 4-5 times more expensive for those oversized bolts and parts than just buying a regular holdfast clamp.

[@DiegoSynth]

Not even taking into account that you need like 5 machines running on 5 expensive / overcomplicated gigs. I mean, if you show how to make it with a jigsaw and a drill press; fine, alright. But if you need a NASA lab to build a clamp, then it's kinda killing the purpose and wasting our time as viewers. The result is beautiful (except for the wooden block with the nut that is gonna get loosen everyday meaning a butt pain), but one has to consider if it's worth it.

[@MuseLeathercraft]

Brilliant! Thanks 🙏 G

[@roseericson3828]

Thank you for sharing your great ideas. Amazing

[@roseericson3828]

Also I wanted to say I love that you used a bolt because anyone can get a bolt from the hardware store. What if you drilled your hole at a 4 or 5 degree angle. The screw down would be angled and would snug into the hole as you tighten it. So electrical shrink tube and a slight angle might help from tearing on the holes. I got so happy when I saw this post. Please keep us informed. 😎

Nice! I'm copying this but I am going to cut the wood to travel the length of the aluminum square tube to provide extra support. As far as the threads cutting up the wood table I was thinking of putting on some duct tape.

[@peterbeyer5755]

Another person suggested shrink tube over the thread, I’m going to try garden hose and have a smaller diameter bolt.

[@alfredomarquez9777]

@@peterbeyer5755 I already tried garden hose, but found it somewhat on the too soft side... Another person suggested filling the space between threads with epoxi (I would use a steel-filled epoxi, like "JB Weld" as it is more resistant than unfilled epoxi...)

[@f.d.6667]

Totally awesome! ... but you need to have a (clear) plastic deflector or protection thingy to cover the end of the blade - it that blade comes loose or snaps, it will aim at your eyes!

[@TheUncleNa]

Love this👍

[@SierraLimaOscar]

The threads of the bolts will slowly "chew up" the hole in the wooden bench table top. Otherwise nice job as always.

[@jisakukobo]

I worry about that too.

[@SierraLimaOscar]

@@jisakukobo Yes, those big threads are quite sharp. Throwing them into a lathe would solve this - but we are not all lucky enough to have access to one.

[@jisakukobo]

I tried something similar with a simple round bar. As a result, I slipped and did not go well. I think this clamp is slippery because it is screwed in instead of being hit with a hammer. Others suggested the idea of using heat shrink tubing. I'm going to try it.

[@SystemX1983]

What if you don't remove the thread completely but reduce the sharpness of the threaded bolt? Then the bolt still has some small serrations that would grip, but won't bite the hole larger because it's dull. Edit: I'd also put a wooden Block inside the fixed side of the squared tube, as the force applied to the clamp might wear the tube.

[@jisakukobo]

I think the idea of leaving screw threads works well. Thank you

[@RafaelMartinez-jb5sy]

Muy bueno.

[@masoudahmad4348]

Can you make one that with a addjust length setting??? Making the handle bit longer so it can be set ???? I think it Wood be a good tool for those with limited space

[@davidgee1585]

I have a Woden X112 holdfast clamp it comes with a collar to protect the hole in the bench, there were similar ones by other tool companies, to stop hole enlarging over time. It would be possible to replicate this, if you had a concern for your bench. Probably depends how often you are using these, they seem a very reasonable way to hold this jig down.

I like that you use tools hand electrical machines, which are accessible also for people, which do not have workroom, and have to do in kitchen, etc.. I am thinking of portable/foldable (!) : workbench, stand for belt sander, angle grinder, and circular saw.. Has to be foldable, or at least should be disassembly, no room to store it.. 😉.
