Excellent Holdfast Clamps made from screws

[@EngineerMikeF]

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.

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.

[@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.

[@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!

[@cbpuzzle]

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.

[@MisterTee2010]

I definitely need to make some of these.

[@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.

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!

[@googleyoutubechannel8554]

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.

[@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. 😎

[@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

[@nikolaymihaylov6662]

So simple, yet so brilliant! Thank you, Hiro! What do you think is the minimum depth of the workbench hole for good clamping pressure? My workbench top is 50 mm thick.

[@HAGmbHkeG]

That should work. The heavy duty steel welding tables I've used are 20 mm thick and have 28 mm holes, although the holes are a much tighter fit with the clamps. But 50 mm for M20 with 20 mm holes should work fine as long as the clamping arm is long enough - clamp too close to the hole and you just pull the clamp out.

@@acerjuglans383 Oh YES! I made some from 18 mm plywood, cutting them in a circle and then using some holesaw to create the cuts for the fingers of the hand having more grip.
