Using a T4 Router as a High-Speed Spindle on the SIEG X1L Milling Machine

The TREND T4 variable-speed (11-32,500 rpm) router provides an affordable alternative to high-cost ER11, ER16 and ER20 High-speed spindles.

As part of my project to convert my SIEG Milling machine to CNC, I wanted to see for myself how easy it would be to fit a high-speed spindle to the Mill at reasonable cost. I have [...]

PCB Milling Diary – April 12th 2012

(see supplemental)

I’m playing catch-up here. The contents of this post refer to work over two days old, delay in writing it up is due to other, more pressing matters.
The good news is that after using LineGrinder to generate the G-Code from my little PCB, the two mysteriously-missing areas on the [...]

PCB Milling Diary – April 8th 2012

A great deal of what we see on the Web, project-wise, is the ‘finished’ product. Every questionable decision has been ‘revisioned’, and what warts remain are carefully hidden, or presented as ‘features’. Yeah, I know this is a pretty cynical view, but unfortunately, nearer the truth, than even I would like to admit.
One of the [...]

Hackit & Bodge Coat of Arms!

Look! At last! The management have decided to employ a coat of arms. The crest will adorn a range of dreadful tat dredged up locally here in Cullercoats, as well as imported at minimal cost from sources in the far-east which have signed a declaration of employing only sweated, underpaid, and child labour.

The decision was [...]

A Versatile Crystal Calibrator

Build The Hackit & Bodge Crystal Calibrator

Hackit & Bodge Crystal Calibrator – completed prototype

A while ago, I played around with changing the transmit and receive frequencies of a cheap FM Wireless Microphone rig. The only equipment I had was a trusty old Alnico scanner bought in the nineties. Although this was sufficient (or so [...]

Re-create The Hackit & Bodge SGV1 Signal Generator

A JFET-based Franklin oscillator reprises 50’s valve design in this rough & ready 400KHz- 12MHz offering.

Hackit & Bodge Signal Generator – Recreated Prototype

Yep, I believe mine was built using a couple of EF80 TV pentodes – ‘cos they cost – nothing!
My memory of it is shaky, but quirky and temperamental are adjectives that spring [...]
