Sensitive drill press

[Pete.Participant @pete-2]

This little thing popped up in my ebay feed a couple of days ago, and nobody else had bid on it because I think it had been listed with a poor description of what it is, might be worth a punt, for half what the motor would cost, got it home and it's nice little industrial quality drill, made by a now closed company in the UK 'Rayment Tool Design' the drill is a RTD 'J ' type.

Anyone know anything this company and their tools? Can't find anything online.

Wow, certainly different. You could hang a sack of tatties on the hook & go make a cuppa ,while it drills the hole for you.

Bit small for that, might be better off with a bag of grapes.

I have one, which is badged Multico (cast in to the horizontal arm) which is a brand I normally associate with woodworking machines. If yours has the single phase cap-start 2800 rpm motor, it may be a good idea to run it on the lower speed belt configuration for a while before changing to the high speed to warm up the bearings and reduce friction, otherwise the motor can take so long to get up to the speed where the start winding centrifugal switch kicks out that the start winding burns out (how do I know?). I intend to put a 3-phase motor and vfd on it some time.

I've got the exact same model, given to me by the electronics assembly company I use. I don't know anything about the company, but the drill was designed to be used for drilling PCBs.

I found 1 photo of one, looks very similar, but not the same, the multico has 2 t slots running front to back, this has 1 running left to right.

That's interesting, it doesn't take up much room, I might keep it around and make a low profile x y table for it.

RTD – Rayment Tool Design was my grandpa’s company based jn Hampshire. As a child I spent hours in his workshop and remember playing with this exact machine!!

And of course, if you did use grapes to add weight to the arm, you could easily modify the applied force to suit a wide range of hole sizes.

Or you could use nuts – threaded ones, then you have everything from 6BA up to 7/8 Whitworth to vary your loading. Hours of innocent amusement …

cheers, Tim

Hello and welcome; do you still play with engineering bits?

Slight digression, has anything been published about adapting a Dremel to a GHT pillar tool to make  a pcb drilling machine? Save me wracking what limited brain I have left.
