Mini-workbench Mk. II
Boys and Girls,The jury is still out as to which group I belong to more shekels than I confess to the taxman or less brains than I brag to my kids about.Last September (2018) I was at the very disappointing Timber and Working with Wood Show in Melbourne and out of sheer frustration from the presenters and content, I purchased this H & T front end vice,
I won't post the link to the WEB site in case I lose a few readers through cardiacs due to the realisation of my sheer extravagance when confronted with the RRP.But where do I put it? I already had this H & T Gordon purchase,
from a previous brain freeze countless years ago. I planned to put it at the end of my old mini-workbench
which I built circa June 2016. Now this workbench has been a gem and has served me well so I was hesitant in making a new one, however, the old one was heavy as it was out of hardwood and the vice was steel. I planned to make the new one out of lighter pine and the vice is aluminium and why not add that shiny tail vice to complement this shiny front vice.Didn't Sketchup this one as I had the basic measurements and design from the first one (self flagellation will follow).Other than the vices, the major differences between the two was,
Down to the workshop and laminated 2 finger jointed pine planks (can't remember original dimensions) to give me an exact 40mm x 240mm x 1047.4mm tabletop. Exactly 1047.4mm you may ask and I reply… well, as I plan all my projects, that's the length I finally finished up with, so I'm insisting that that's what I actually designed. FYI, the bench stands 200mm high (and of course 1047.4mm on it's end).Glued some packers for the vices , marked the bolt positions and dragged it of to the drill press… figuratively speaking of course as being made of pine it didn't have to be physically dragged.I clamped the workbench to to the drill press's top, but as the press's spindle couldn't be move, I found it a tad easier to add an extension plank,
- Use pine instead of hardwood to minimise weight.
- Used my UKJ Parf jig for exact placement of the dog holes rather than manual matrix layout.
- Used wood threaded 10mm stainless hex head bolts instead of coach bolts and nuts.
- Used 6mm metal bolts with wood threads rather than screws for breakdown purposes… (done before my Domino purchase after they released their new breakdown hardware).
- Provided for using Rockler Universal Fence Clamps rather than bulky C/F/G type clamps.
for ease of allignment,
Drilled 6 guiding pilot holes.
Confirmed hole position and marked the bolt length/depth,
Drilled out the pilot holes with a 7.5mm drill bit to tap for 10mm bolts at a later time.Hogged out the recess for the tail vice and then added a packer as the vice was thicker than the tabletop,
Usied SketchUp (can't stay away from it) to design and laser cut a cover plate for the tail vice,Using the UKJ Parf jig's rulers, I marked out the dogholes and drilled the required 3mm pilot holes,
Then followed the instructions (ugh reading) and bored the 20mm holes using the 3mm pilot holes, the jig and a 20mm TCT forstner bit,
Made the legs and glued and bolted the support base (bolted to get better strength with 6mm x 70mm bolts using the wood threader),
The cylinder barrel of this vice made it easier to cut out the leg recess than the awkward shape for a “standard” vice. Tried using the method of cutting with the kerf on the edge to provide dust extraction relief and when I realised the hole had to be centered, I made another leg and used the relief hole principle.Drilled some 8.5mm holes into the legs to permit using Rockler Universal Fence Clamps for securing the mini-bench to a supporting surface,
(DOH! I had spare pictures)...Drilled and tapped 6 holes to accept 10mm bolts. Ratcheted in the bolts and tested squareness and operation. I then soaked the bolt holes with tung oil and when it came to the final bolt insertion, I had to use a pneumatic gun to seat the bolts as the buggers were fighting back against a manual wrench.
Fitted the tail vice with the cover plate,
The tail vice comes with a profiled brass dog,
with the following four faces,
One of the features of this tail vice is it's movement. It comes with a small textured knob at the end which exerts incredible pressure with the minimum amount of force. Just two finger tightening will mar the wood if you insist on using brute force on the work to prevent any form of movement.
- Flat face.
- Slightly concave face for rough surfaces.
- Slightly convex face for contoured surfaces.
- The fourth face is reserved for thrillseekers that want to shape their own unique face,
Couple of pickies of it in use,
Now the main vice (called main to avoid confusing this tail vice with the tail vice… I think I may have called it a front vice but I'd have to read to find, confirm and correct it) does not come with an onboard dog like most vices, to permit clamping against dog(s) on the table top,
Being too gutless to drill holes into my shiny new (and expensive) vice I hit SketchUp seeking a solution. It didn'r say much, but eventually I finished up designing a cover box and laser cut it after allowing for profiles to fit the curves of the vice,
I provided a pseudo-dog on top of the box to press against the work DOH! The top of the box (out of 6mm MDF) naturally sat 6mm above the vice top (approx. 5mm above tabletop as the top of the vice is about 1mm below tabletop) so this extension was unnecessary,
It shall stay there until it really pisses me off and then there'll be a circumcision (snip).There have been times when I need to clamp non-parallel bits of timber,
For which I have made up this beveled jaw backing which pivots on a dowel,
that fits into a same diameter groove down the main tabletop jaw,
For wider timber, I simply use the box with just one round dog in the middle of the tabletop for the brace. No picture provided as the non-parallel stunt timber refused to put on weight for just one photo shoot.These Rockler Auto-Lock T-Track Hold Down Clamp have been customised to permit static fitting to the tabletop,
and can accommodate various thicknesses of timber without adjustment,
I also use these quick adjustment clamps to wedge long pieces of timber without the need for bulky clamps,
The bench also provides a resting place for a spare Ryobi battery,
for those times I'm too lazy to walk 2 meters to get another spare.If you look closely, here is the resting place of the old mini workbench.
Now, as always… most of the time… only when I do it… for all of you that also hate reading grab some popcorn, put in the ear plugs and don the sleep mask before you try to connect to this video I made so you don't have to read the above.PS. If you found the read boring and the video tiresome, save wasting your time on the above and check out
this animation of this mini workbench in SketchUp.
