I appreciate the tempo as it’s not as frantic as most hipster KZbin woodworkers is. And the simplicity and lack of snobbery that is all to common with many influencers/woodworkers some times. Definetly giving you a follow and I’m definitely going to use your tips and tricks when making my own set of dogs like these. As most of my comments rarely consist of elaborate flows of words I’ll end in my ordinary manner: 👏👏👏

Yes, I've tried doing a few fast-paced edits, but they're just not my thing. Also, a tiny channel like mine has more reason to be modest than most! 😀 I've been unwell with COVID lately, which has slowed me down quite a bit. I've made a few other variations on bench dogs since I made this video, so I'll see if I can manage to make a short follow-up vid covering those tomorrow.

This is really Cool. Top class. Without using expensive power tools. And very longggggggggggg "CLAMPS"

Amazing work for just 4 pallets

[@TightwadWorkshop]

Thank you! I needed to do a lot of planning beforehand, and it only works out with 4 pallets if all of the boards come apart without breaking. The bench being constructed in the video series is actually the mk3 version, I made 2 others prior to it to get the design right.

[@larsfrandsen2501]

Yes, perfect!! Just what I need.

Great, very nice, I love it. Especially part and tip about flatten tips of holdfasts.

[@TightwadWorkshop]

Glad you liked it!

Complimenti lei è un ottimo falegname.

[@TightwadWorkshop]

Grazie, ma sono davvero solo 2 pagine avanti rispetto alla classe nel libro di testo! :-)

[@zacbrown935]

Well done!! Looking forward to the next video!! Keep up the great work Sir!

[@TightwadWorkshop]

Thanks, I'm glad you liked it. :-)

I think there would be the lesson in sharpening the hand saw :). It would be useful lesson for future wood workers.

[@TightwadWorkshop]

Unfortunately those cheap hard-point handsaws can't be sharpened, but I will be recording an antique hand saw restoration video tomorrow. :-)

Hi Tightwad May I ask two questions about the performance of the wooden holdfasts and the grippiness of of the 19mm dowel stems How would you rate the timber holdfast in its ability to prevent sliding and vertical pressure as compared to a metal holdfast and did you consider abrasion of the stem so that it locked tighter to the dog hole upper lower opening circumference? I feel that your design is particularly elegant , MP10 heads and hardwood ( assume it to be eucalypt) stems Thanks a heap

[@TightwadWorkshop]

Hi Andrew. Just a quick disclaimer first, I'm basing all this this on my own experience with using these holdfasts for the past couple of years. I'd never used holdfasts on a workbench before this. A wooden holdfast like this doesn't give as much grip/holding pressure as a clamp or a vice. They're definitely not firm enough to use for glueing up boards, these are just for holding workpieces on the workbench. You're also relying on the friction between the workpiece and the workbench to stop it from sliding away. Depending on the task you're trying to perform the holdfast might not be enough, in that case I use a peg or "dog" in one of the other workbench dog holes to give me a rigid "stop" to work against. I expect that a forged metal holdfast would give better clamping force, but since my workbench has a softwood top it'd also erode the dog holes much more quickly. That's also the reason why I made the dowels a relatively snug fit into the dog holes (to spread the clamping forces over a bigger surface area on the inside of the holes). You're correct, the the stems is are 19mm diameter "Tasmanian Oak" dowel from Bunnings (and to my knowledge "Tasmanian Oak" is just a label meaning "miscellaneous Australian Hardwood").

[@travelingworm]

@@TightwadWorkshop actually the hole diameter within sensible size is not the determiner of the gripping ( locking) power it is the force exerted by the stem at the top back of the hole and the bottom front edge under the bench, putting some ribs on the stem is more effective - course sandpaper is also an option - look at Armortech metal stem pressure hold down for that concept. Must say I “love your work” and the slightly contrarian wit in which you discuss things, also was love you sign on animation of tightwad Thanks for your sharing contribution to

[@travelingworm]

@@TightwadWorkshop I will send a graphic of the holdfast mechanism to grip in the dog hole if you wish

[@TightwadWorkshop]

Yes, I'd be happy to see that. You can e-mail it to: [e-mail]

[@TightwadWorkshop]

H Andrew. Yes, I understand that if I'd made the pegs smaller or the holes bigger then the holdfasts would probably grip better. I went with similar dimensions for the pegs and holes because I was concerned about eroding/deforming the workbench holes too quickly. I didn't actually run any tests to see if that was going to be a problem, but since the workbench is made from softer material than the pegs I guessed it might be a problem over the longer term. I'm glad that the video was useful to you, I try to make each one a little better than the last. :-)
