vertical slide

<< < (2/4) > >>

John Hill:
Good idea Stew though if I use a bush without the recessed nuts thingy I would need longer bolts in the cross slide which might be OK, another line of thought to consider! :coffee:

bogstandard:
If you are making the centre spigot larger to fit the hole, then all the bolts are there for are to hold the thing in position.

I am sure it would be easier to make up two new holdown bolts to roughly the same pattern as the others but a little longer, rather than arsing about with recesses and things. It takes only a couple of minutes to take the crosslide off to get the old ones out and the new ones in, and because of the tapered gib, that only takes a few seconds to set up afterwards. It isn't as though you will be swapping and changing every few minutes. As for the holes, just file them in the general direction they need to go and make elongated ones.

K.I.S.S.

John Hill:
K.I.S.S. indeed John.  Dont think for a momet that I have not considered a bit of bodgery with a round file and calling it done but the holes in the slide's base are already recessed and with a sloping bottom to the holes so I do have to put something in there!

But enought of this,  chores are done so down to garage I go!

bogstandard:
John,

I can be very difficult making 'relocation' suggestions without first seeing the problems.

I think what you have is a perfect catch 22 situation.

You need a vertical slide to hold your vertical slide, so that you can machine it so that you can fit it to your machine.


Always problems  :doh:

John Hill:
This afternoon's effort!


This is the problem, the spigot is too small and the bolt holes are too close together.


A bit of old junk in the lathe, it is part of an old pulley, or something.




Turned off a ring and fitted to the spigot, it is a nice tap on fit but would be better thicker but thats not possible with this particular bit of rusty steel.



A piece of round is turned to fit the recess in the slide base then the end drilled and tapped to take the fixing bolt.




Two of those made, cut off and the ends squared with a few minutes of filing.  This looks OK but is not satisfactory, the holes being off centre mean the nuts are pulling the bolts sideways a little and I fear too much pressure might damage something, maybe crack the casting?



It is good enough though to prove the concept and here we have the slide being used for it's first job drilling a neat row of holes in a piece of junk metal.
