plasma design 8' x 4'

Looks good mate, well done on getting this far!

I'm liking the sprung tension on the pinion, never seen that before.

That's looking a good 3 month work ads...! When you've got it all tuned up it'll be a nice robust machine.

Just a Q: What are the Vbearings running on on X and Y? It is the proper machined rail, or have you found some alternative (angle iron, or something)? And did you use eccentric bushes to pull the bearings onto the rails, or some other method? Just curious because my next machine will probably be using v bearings.

Anyway, looking good!

X is running on home ground rail (an angle grinder on a skate) check out Mechmate forum they build some fantastic routers.
Y is running proper ground rail.
yep, used v bearings on eccentric bushes from superior bearings in USA.
Had motors running today, 80% satisfied. Running out of time now as I wont be allow to play with over Christmas!

christmas is past!!!:naughty:
how is your build going i am hoping to build same sized plasma/router but racks etc to expensive,thinking about belt drive(see my linear drive thread)
where did you buy racks etc and how much if its not to cheeky to ask???

Cutting metal now. Big learning curve here!
Have already sold some cut plates off the machine.

The x axis rails are ground angle iron, have a look at the mechmate for info on this. Don't dismiss the idea as mad and bound to be inaccurate! Have a look at what the lads build on the mechmate.com. The Y rails are no2 ground v rail from Eurobearings. The V rails from superior bearing in USA. The geared racks from WMH bearings Tamworth.
