Thread: Dan's Blackbutt Roubo Bench
-
22nd February 2010, 06:54 PM #91
Other than a little sanding and finishing the shelf is complete. Made of 18mm blackbutt and inset into a rabbet through the stretchers.
The tongue and groove joinery was not fun. A easy operation on tablesaw, or router table... No so easy with a circ saw and a router (especially when the router fence decided to drift a little.) Ideally, I would prefer to use rabbet planes for this, or fixed machinery failing that. We got there in the end, with tight joints, but I wouldn't do it again with my current toolset.
Also, note the gap in between the front stretchers... stay tuned for further info on the sliding leg vice.
Figures: 1650mmx520mm. 18mm thick. 42mm inset. 15mm rabbet.My blog: ~ for the love of wood ~ - http://theloveofwood.blogspot.com/

I've made a little process on the sliding leg vice. Instead of cutting into another slab, I decided glue up some off cuts. The slabs I've been using are trapezoid in shape so each one left me these long wedges. Machined, glued, ripped, re-machined and ready to roll.
A trip to bunnings landed me the required bolts, I also picked up some aluminum angle to re-enforce the top tongue. Leaving the new wheels the only piece I need.My blog: ~ for the love of wood ~ - http://theloveofwood.blogspot.com/

A few small steps for the work bench...
1. Tapping
18 months ago I wouldn't have known what a die and tap set was. (Essentially; it's a cutting tool designed to make male (die, eg. a bolt) and female (tap eg. a nut) thread. The benchcrafted glide requires some tapping for it's bolts.
After reading various forum posts about which set to buy and looking at different websites (including ebay) I decided on the 40 piece kinchrome. I found a company Transquip which offered a good price. It arrived in 2 days. They were pleasant to deal with. (Even when the bank forgot to activate my card.)
I was amazed how simple it was to use. Drill your hole. Screw in the tap. Screw in your bolt. I can see this having a few applications.
2. Handles
I've requested help for someone to turn the handles required for the parallel stop. See forum post.My blog: ~ for the love of wood ~ - http://theloveofwood.blogspot.com/

Frame query
I am about to embark on a very similar bench but one nagging thought will not go away. My top will be around 650mm wide and be made from Tassie Oak, I know, not terribly exciting but this is a workbench, not a dining table.
The top will be around 100mm thick and I am looking at just having 4 post legs with long and short stretchers on the lower half of each leg.
My concern is this. Will the middle of the top tend to sag across its width and length seeing as it will only be supported by legs 100 mm x 100 mm at the front and back edges? The legs will be inset about 400 mm from each end and the length of the top will be around 1800 mm.
I am considering putting "cleats" or stretchers at the top of the legs across the width to try and avoid this possible problem. In the collective wisdom, is this needed or is it over-engineering?

In response to your question. There was an article in a recent AWR about the engineering properties of wood. I believe stiffness is increased by a power of 4. So even a slight increase in thickness results in remarkble increased stiffness.
If you top is 100mm thick, and on legs (1800 - 400 x 2) so 1m on the outside of the leg. I don't think you'll have too much problem. Think of a dinning table... they are 30-45mm... not 100mm.My blog: ~ for the love of wood ~ - http://theloveofwood.blogspot.com/

It is across the width that I am concerned about, not along the length, in other words the 650 span which will be made up by 50 mm beams, not the 1800 mm length

I've made some progress on the wheel brackets. I've opted for a modification of the standard design to allow the bolts to mounted on the side reducing the height required.
The joinery uses 3 small tenons (~10mm square) wedged. Cut by hand with a dozuki saw. I've included a pic of some of my tools (as they were still on the bench). The fit was fairly good, but not perfect. I'll use some epoxy to fill in the gaps.
I did make one modification. Originally the tenons were the width of the wood ~18mm. To cut three mortises this size removed too much wood and split the back piece 4 times. (Lucky I made a spare.)My blog: ~ for the love of wood ~ - http://theloveofwood.blogspot.com/

The most complicated and innovative part of my roubo build is the sliding leg vice mechanism. Here's progress to date...

Another piece to the puzzle arrived on my bench today.
The four wheels needed for the sliding leg vice. Solid nylon, 2" diameter, 1" hub, slotted perfectly into the 54mm holes cut into the wood...

What is the clearance from the edge of the wheel to the edge of the hole?

I've threaded the holes for the bolts. I fear my drill table was 2-3degrees out so it's a little tighter than I would like. I might loosen it a little. Gently Gently.
I haven't drilled the centre section, that's why the bolts are hanging out. But you get the idea.My blog: ~ for the love of wood ~ - http://theloveofwood.blogspot.com/
