I've posted up photos before of hobbed pulley drives. It's a process that works very well and gives a professional result (very similar to what Wilesco does on their drive pulleys). I've done well over a hundred brass and aluminium drive pulleys now.

Here's a vid I did a few years ago of the process -

Running one of Trev's delightful TTB V2 engines with some mods and driving a Baker fan and putting the engine under load.

Trev was an absolutely prolific maker of a range of beautiful brass and copper engines and accessories in his small backyard country shed.

I have joined 2 bits of 2020 extrusion for the X axis but I am not sure I am going to get away with it as there seems to be slight resistance when passing the join.
I may need to order a complete bit.

Been a few changes in the last 2 months, for a while my backyard looked like a war zone - complete with craters. Eventually the craters were filled with the foundations for the garage and the bulkhead stairs that I am adding into the basement. For the 18 years that I have lived here I have NEVER had easy access into the basement with bulky objects - before winter I will.

There was a major construction hiccup but that has been resolved. The major hiccup was that I had told the lumberyard that I wanted attic storage roof trusses - no king post. When the trusses arrived, they were king post trusses. That was their boo-boo not mine, but it was a 4-5 week delay. My new garage now mostly has walls and a roof, The wall framing is complete, sheeted, covered with Tyvek, has the windows are installed, and the siding is about half installed. The widow's walk that was demolished when the deck and porch were demolished, is temporarily back now. It WILL become a 2nd floor sunroom.

I lost my construction crew for the last week, it's county fair time and the crew boss' kids had entries in the fair. He also happens to be the construction company owner, so we took a week off. That's not really a bad thing since the temperatures and humidity were both high last week.

There's still a LOT of work to be done, we're going to strip the old stucco off the second floor of the house and re-side it to match the garages. We've also got to build the sunroom, cut the opening for the bulkhead stairs, and build those stairs. Then we need to build the landing and stairs from the kitchen into the garage. Part of that landing will be a drawbridge covering the bulkhead stairs into the basement. Did I mention that as we were doing the demolition it started to strip the brick veneer off of the west kitchen wall? We've still got to figure out how to deal with that, but I've got a clever plan M'Lord.

I would guess the v wheels will be fine . There's little to no forces moving them around and they work fine for most bed slingers.

I must get on with my dual hot end for the frog spawn , I put it away last year and have yet to start again
