This thread might take a fair while to develop. Its been 12 months in the making already. My Arduino Rotary table controller project got me interested in CNC but I did not want to do the obvious and convert my mill to CNC. I eventually got interested in CNC plasma cutting and I started about 12...

I thought I'd share a link to a handy gear calculator on a client's website that lets you calculate module and DP for an unknown gear. Sorry but you need to measure the OD in milimetres (25.4mm per inch) http://www.gearconcern.com.au/gear-size-calculator/ Enjoy!

EDIT: Latest Sketch (V9) is on post #155: http://www.homemodelenginemachinist.com/showpost.php?p=262782&postcount=155 This is a substantial upgrade that supports ramping stepper speeds up and down and also saves defaults in the EEPROM so you don't have to recompile it if you change your...

I was watching Tom Liptons videos on how to cut a taper and saw how he used a sine bar to set the compound angle. https://www.youtube.com/user/oxtoolco I had a go at it but found it pretty hard to indicate the compound into position. after a bit more research, I saw another quick idea...

Guys, Recently, I have found I am using my collet block more and more. I have always had trouble with the collars used to tighten the collets that came with the collet block set. Yesterday I decided to do something about it! This is what I came up with: This has been machined...

There seems to be heaps of threads on ball turners on the forum but not much said about using a boring head to do this. So here is one set up to fit on a BXA tool post. When I bought my boring head, I bought an additional straight shank mounting flange for it. It had a 20mm diameter...

I have a set of fractional drill bits on my wish list. These usually come in two sets, up to 6mm and from 6-10mm in 0.1mm increments. I was at my bolt shop today and I asked them how much the Sutton sets cost and they gave me a quote that was affordable to mere mortals like me. The only...

Well, I have been meaning to buy a belt driven compressor for a while and I spied this one on Grays Online Auctions recently and because it was not far from home to pick up, I thought I would take a punt on it sight unseen based on this photo that was in the listing Pilot is a very good...

Well, I finally have it finished. A big thanks to the guys on the forum here who put together the EZ engine and the build instructions. These plans are the reason why I joined this forum in the first place as I stumbled on the plans googling "Metric Steam engine plans" way back in November...

You guys must get sick of seeing these sort of posts, but here is another one! Hare & Forbes wanted AUD $500 for a QCTP (I think it is a Dickson Style). The salesman reckons no one bothers to buy it as it is a major job to fit it to the AL320G that has a tool post like this: I had seen...

Hi guys, I am fitting a BXA toolpost to my new lathe and tomorrow's job is to drill and ream a 12mm hole about 40mm deep in the centre of the 16mm bolt I bought today. I've already drilled an 8.5mm hole right through the piece (as an 10 thread is required as well) and have a set of unused...

Well some of you may have seen on some other threads last weekend, I took delivery of a new Hafco AL320G lathe and a Seig SX3 mill from Hare and Forbes and sold my old lathe/mill on eBay during the week (which paid for half the mill) Anyway, while I was waiting for some colletts and tooling...

Hi guys I thought I better post up a picture of my shop. well we don't call it a shop in Australia, It has to be a shed. Mine is tiny weighing in at 2.4m x 4.8m. For those who still work in feet, I will leave it to you to multiply those numbers x 3.28 to work it out in feet! It is a bit of a...

Hi guys, I just wondered if you can help me out here? It is a simple question, so please bear with me, I have a part I make It is pretty simple really. It is 100 mm x 32mm x 8mm mild steel. It has two holes. One is tapped to M8 and the other is countersunk for an M8 machine screw. I started...
