Refurbishment — Arboga E100 (February–March 2018)

The Metal workshop's Arboga E100, No. 46912, received a major refurbishment in February–March 2018, carried out by Erik Cederberg, Theeo and Bullen. The project included complete disassembly, cleaning and refinishing of the castings, bearing renewal, work-table repairs and reassembly. Chris's wooden replacement handles are documented as later work in July 2020; see the maintenance log.

Use the main machine guide for the current setup and operating information, and the maintenance and repairs log for later work.

Starting condition and disassembly

When acquired, the drill press had chipped original paint, rust in many places and some bearing noise. It was fully disassembled into its components for the refurbishment. The photographs show the opened gearbox, dismantled castings, gear and shaft assemblies, quill, motor rotor and stator, and smaller fittings.

Cleaning and refinishing

Most castings were first degreased, then chemically stripped of paint in a heated sodium hydroxide solution in the large ultrasonic cleaner. They were then sandblasted and painted with silver Hammerite hammered-finish paint (hammarlack). Parts too large for that cleaning setup, such as the foot, were sandblasted and painted directly.

The internal mechanical components were degreased using cold-degreasing liquid in the heated ultrasonic cleaner. The column was cleaned using rust oil and Scotch-Brite abrasive nylon.

Bearings and reassembly

All bearings that were relatively easy to replace were renewed with new SKF bearings. The components were then reassembled and lubricated.

Work-table welding, resurfacing and transport damage

Bullen welded up the existing damage on the work table. The table was then sent to a nearby mechanical workshop for resurfacing. During transport there, it was unfortunately dropped and a piece of its rim broke off. The workshop re-cut the table face to restore a flat working surface. The underside photograph below records the missing section.

Later wooden locking handles — July 2020

The refurbishment account noted a missing table-locking handle. A later photograph and member update document that Chris turned and fitted wooden handles for both the head/column and table-support/column locking levers in July 2020. The dated photograph is kept with the July 2020 maintenance entry.

On/off control box already fitted since 2017

The original on/off buttons had been removed before this refurbishment. Since 2017, power has been switched on and off using a motor-protection circuit breaker (MPCB) in a box mounted on a bracket at the top of the column. This was an existing modification when the 2018 rebuild began; the enclosure is visible in the opened-head and reassembled-machine photographs.

A Schneider TeSys GV2ME06 carton is visible beside the machine in the first refurbishment photograph. It is packaging evidence; the fitted breaker's exact model and current setting have not been recorded from a readable device label.

Record source

This project account and the historical photographs were supplied by a member on 14 October 2026. The work period, contributors, cleaning materials, SKF bearing renewal, wooden handle, table welding/resurfacing, transport damage and pre-existing control-box arrangement come from that account. The before photograph is dated April 2017; individual dates of the other historical photographs are not recorded. A later photograph and member update supplied on the same day date Chris's replacement of both wooden locking handles to July 2020; this handle work is recorded separately from the 2018 refurbishment.
