Type

3 axis, Rhonmac R1824 (460mm by 610mm), CNC, bench-top, router machine, with a longer (75mm) Z-axis and with a (MB01) spindle motor mounting bracket for a Kress spindle-motor/router with a 43mm diameter mounting hole. The machine was made by Reg Pugh Engineering (Rhonmac) in Wales (March 2011). It is a heavily-built, well designed machine.

Safety limit switches for each axis were rewired using screened cable to remove spurious stops. The screened-lead cables enter the machine controller on the rear panel using audio-coaxial plugs and sockets.

If you are genuinely interested and want a few more specific images of the machine please email me and I will do my best but there is nothing better than seeing it directly.

There is no rust on the screws or rails. The machine has been kept clean, well oiled (and run every month) and stored in normal household temperatures. None of the axes have ever been run into the hard stops.

This machine performed perfectly when I used it to cut some boxes and has had very little use (see reason for selling below).

I used EMC for Linux operating software and found it better than Mach 2. I have a disc copy of this software if you want one with the machine. You can also download a copy from linuxcnc.org.

This machine could be easily adapted to accept a laser tube for laser cutting (observe safety precautions).

Please note that the Dell PC, keyboard, mouse, flat-screen monitor seen in some images are not included in the sale.

Kress Router (‘spindle motor’)

FME 1050 spindle motor: 1050Watts, 230volts, electronically variable speed 5,000 – 25,000 r.p.m. Used for approximately 10 hours only and in perfect condition. There are 4 collets with the router plus many cutters - some are practise cutters and others high quality. Most of the practice cutters are unused and none of the quality cutters have been used.

3-axis Controller

The Rhonmac 3-axis controller supplies 50volts for the 3 separate control units, and contains a large heavy-duty toroidal transformer, bridge rectifier, smoothing capacitor plus a cooling fan, the stepper-motor drivers, the connection circuit boards for the emergency stop switch and safety limit switches plus the connection to the controlling computer.

The individual stepper motor drivers are 'Microstep Driver' and can be individually set up, using the miniature switches along the tops (on the small red panels between the green connector blocks). They are all set up to run the motors correctly.

The emergency stop button mounted on the front of the machine connects to the rear panel of the controller, as do the axis limit switches. The mains lead connector is on the top left (cable supplied). The large multipin socket on the right connects to the parallel (LPT1) printer port on a desktop computer (the cable is supplied with the machine).

Vacuum unit

This is an Axminster unit and very efficient. There is a large diameter (4-inch D) hose with it. Again, it has only been used for a little over 10 hours and performs perfectly. There are some spare filter bags with it.

Usage

The machine has been used for approximately 10 hours to make the 5 boxes in the images (see reason for sale).

The hardwood boxes have been made using elm (difficult to machine well), oak (machines well) and some old teak-like timber (the dark one, which, being oily, machines perfectly). They are all very accurate, the lids fit the boxes perfectly.

Prototype boxes (mainly with lids on) made to check the machining

Location

Berwick upon Tweed, Northumberland, England, close to the A1, around 45 minutes drive from Newcastle upon Tyne or Edinburgh.

Viewing and buying

Contact the owner to arrange viewing during daylight hours. It will be run to show that it works flawlessly. If you like the machine and want to reserve it, a deposit will be required.

When full payment is received the machine can be collected. This will be agreed with the potential buyer who has paid the deposit.

If the potential purchaser fails to pay the full price then all extra advertising expenses plus compensation for lost sales could be taken from the deposit. Please be absolutely sure that you want to buy the machine before paying the deposit. I will probably refuse any more viewings after someone pays a deposit. Please be fair.

The buyer can also pay for the machine on first viewing, by a means acceptable to both buyer and seller, and take it away that day. Email for details. A fair agreement is wanted, satisfactory to both parties. Full payment will be required (to be arranged between seller and buyer) before the machine can be taken away.

Price £1900

Note that it needs 2 people to carry the machine and I cannot help you with that. The machine weighs a little over 90KG so bring a friend when you come to collect. The machine fitted into a small Suzuki Ignis hatchback and will fit into a small van easily.

The dimensions of the machine are approximately: length 990mm (including stepper motor); width 990mm (including stepper motor); height (with Z-axis lowered) 700mm (including stepper motor).

Reason for sale

After ordering the machine and paying for it from Rhonmac I had an accident, 3 spells in hospital and a long convalescence. It is now difficult for me to lift anything heavy or to bend over the machine while setting it up to cut.

Note: this machine is advertized in other places.
