Yes it is.

I've slid my blocks on to the rails and removed them multiple times while setting up, using the plastic retainer pushed against the end of the rail each time. No problems so far, although I just know I'm going to have a wobble some time...

cut the rails to length and slipped on 2 blocks this afternoon... don't know what I was worried about :highly_amused:
I assume these are double seals?

is it worth adding the scraper? I assume it is just a case of unbolting the existing seal & slipping it on?

wow cant believe it has been so long since I last posted

progress is slow but steady, various bits & pieces required to complete the x axis frame are now machined except for about a dozen holes... as usual for me... I keep forgetting to take pictures, not that a pile of aluminium plate machined & drilled is terribly interesting

progress has not been as linear or as logical as I would have done myself, as I am working on bits I have while designing stuff like the base frame and control box... normally I would do all the design then start from the ground up...

so... mocking up the bearing carriage for the x axis, the wooden block was made as a model to see how the clearances worked out and to visualise the ballnut mounting method, as I could not see the wood for the trees in cad. once assembled the mounting for the ballnut is obvious immediately. working in wood is an easy and cheap way to prototype parts, the block of 6082 this will be machined from is about £100 and will take the best part of a day to machine so cant afford many mistakes

final design..

gantry risers are finished... ready for trial assembly

upside down but shows how the top plates interlock with the gantry rail to help with alignment

Pics look great. G.

bit more progress, x axis is hopefully "finished" ie only needs minor changes like limit switches and guarding fitting.... and base frame is made, so I can start a trial assembly soon

bearing carriage machining...

and one finished

http://www.mycncuk.com/attachment.ph...id=15199&stc=1

both now done... bit of aping & counterboring then I can start assembling the gantry

Progress is finally being made

Ballnut, 32mm, housing and bearing carriage ready to fit

runs very smooth :kiwi-fruit:

Looking good, thanks for sharing!
