porter_jamie – nice, you’re using pretty big pitch holesaws, what RPM do you run? I do something similar – though with a tube notcher and DeWalt not a lathe:
I had been using some 10tpi holesaws, but tried a cheap Bosch one with big teeth and it was just as happy as 1200rpm.
yes, i would like to try a finer pitch holesaw. run that at about 300 rpm. we got some carbide holesaws to see if they cut any nicer – not sure really. this is only 1″ cds 16swg though not fancy columbus or anything
It was my first time doing dovetails.. i have a jig so it wasnt too tricky, but putting them together, wow… glad i have clamp-heads that i can bung onto any length of wood to use as my clamp.. i needed much longer fixed clamps than i have (i forget the word for this in english)..
Made these, they aren’t finished. Just bare MDF at the minute. They’ll be joined by shelving across the middle of the chimney breast and we are going to get sliding door to go across the lot of it. The reason for the half rail in the nearest one is so the OH can hang long dresses without them getting crumpled at the bottom.
Great Tandem Trike there Ben. Did you know that nobody has yet set a record time for Lands End To John O Groats on a Tandem Trike (Women, or mixed)?? http://www.rra.org.uk/
Yup, three headsets in a line. Two outer ones take normal forks (he wants to try suspension forks), centre one has the bars. Then tie rods with rose joints connect the centre stem to little stubs on the side forks. Angles will be tweaked to tune the Ackerman effect (wheels need to all turn around a common centre).
It’s very similar to how recumbent trike steering works.
The cool bit is it’s going to have a big rack across the front of the frame, to carry tent, sleeping bags etc.
Is that the rationale for it being a trike? – for load carrying capacity? or is it for a rider with balance problems?
It’s for (in)famous Glasgow cyclist Dr Guthrie – he likes tricycles, but he breaks the back axles regularly on his Longstaff trikes. Plus, this way he can have a Rohloff without any complicated gearing setup.
Anyhow, in a break between building bikes, I made a book:
Taken as I was bottling the latest batch. Turned in to a really nice, hoppy and clean session beer. Reckon it’s around 3.5% or so, but lots of flavour.
Crushed crystal malt and Goldings hops, by the way. .
The last thing I made was a very simple jig to make different sized circle templates with for use in our furniture classes. I also made a little video while doing it… 🙂
It now has 40mm bb drop and a 360mm(14.2″) rear end. That’s 2mm clearance from tyre to the seat-tube with 26 x 1.5″ slick tyres when the wheel’s slammed. Handcut track-ends with a 50mm slot and seatstays scavenged from an old trek. Still needs tidied up (top tangs need filed up to the weld) then it’s going to paint.
Super whippy to ride: 74 degree hta, 10mm rake fork, low BB and that tiny rear-end. loving it.
excuse the rust, first ride was in the rain and not had a chance to repaint it yet.
