How about those round rubber door stops with a hole in the middle? https://www.google.co.uk/search?q=ru...HcJvCbMQsAQITg

Good idea Clive.....the stops have to be about 60mm (will measure later) and I think will have to be rectangular....more research needed I think!

Control box & VFD on the wall....

now working on the electrics.... got the correct tool out....

Neil Do you think you will need another bracket to bolt the frame to the wall at the top, shimmed as to not twist the frame

Hope you are only using he hammer to tap the connections into place

There are 2 additional bolts half way up bolting the frame to the wall...shimmed with custom cut bits of pipe 😁 the base is shimmed and bolted at all 4 corners so I'm hoping it's still all square....will tell when I first go to cut later today...

Hammer was, as you suggested, to tap in the wires...who needs screwdrivers?

Don't seem to be able to see any chips though

. Just thinking aloud how about a brake operated with a solenoid that operates when you lose power. It could be on a counter weight steel cable over the top (on a pulley) and then brake the cable.

I didn't want to make and chips...we have a VIP coming to work tomorrow so wanted to keep the floor clean

I have thought about a counterweight...still might give it a bit more thought but for now I think it's going to be rubber parking stops. Will look into (or just ask Dean) a macro to park the gantry when I'm done using it.

I'm also thinking about going vertical with my router (thanks to Dean :) )

What do you guys think about parking the gantry up top and securing it with a clamp/bracket? Would suit my space much better ;)

This will answer both of you.

My orginal vertical machine I used to park at the bottom which was the best place to park for me but could park anywhere I liked as it didn't fall down due to light gantry. Since then I've aquired different machine with gantry using the same design has neil's which is much heavier and like neil slowly creeps down when power off.
So the solution was counter balance and now can park where ever I like. It also takes lot of the strain off the motors while working meaning I can tune motors a little more aggresive if I like.

Don't ask me to show the counter balance because it's rougher than rough(Which sure Clive will confirm) and like every thing I do just for my self it's thrown together to get it working ASAP. To give an idea consists of bit of old timing belt and tractor weight.

Counter weight it is then....
