Second router finished - 8020 Bearings

[bryanrabb]

I didn't make any changes to the MDF, yet. I may still. My mods are as follows:
1) Rotate the x-axis rails 90 degrees because I had the wrong bearings. This actually works out well.
2) I don't think I am going to use the mdf x-axis plate. I am planning on using two delran blocks that are tapped. Each mounted on a piece of alum angle. One will be placed on each rail. This may turn out to really suck, and then I will use the mdf. I can't really say why, but it seems with two blocks, it it a tighter fit. It may actually bind a little, causing it to suck further. Most of my mods come from my ADD. That causes me to work way too fast and screw things up, and then I just try to work around my screw ups.

I will say this, make sure your holes are drilled accurately! Or at least oversize one per extrusion. That way you can square and parallel them. Also, I clamped my endplates together before drilling. That way they line up perfectly. (well not perfectly, but better than if I had done otherwise.)

hey hack
just a idea for your trimmer could you not get a dimmer switch
and try that on the trimmer it would be manual speed control
but most of them will handle enough current I think

hmm or you could do a few set speeds with a scr and few resitors and transisotrs and a couple of up puts from your controller providing it has them

Hack -
Are you still using the 8020 bearings? If so, how are they holding up after long term use?

Thanks

[Hack]

Sorry, but I sold this router about a year ago, before any long term tests could be run.

I keep getting lost in dead-end links. Including the one in Hack's profile.

Hack, please provide a pointer to where I can see your plans?

Thanks!

There seem to be a bunch of different 8020 linear bearings. Some are supposedly rated for "quick starts", there are some that have little wheels, etc.

Which bearings did you use?

[Hack]

I have been trying to post the plans for this router on the site, but have been unsuccessfull. It is about a 2.6mb PDF file. Any suggestions. Like to make these available free of charge to everyone.

Maybe use winzip or make it multiple PDF documents?

I would greatly appreciate if you could share the plans.

[alwaysready]

well if you could possibly email me the plans i would appreciate it.( be willing to email them to others when contacted) so the pressure isnt all on you. we could even list the people who have the file for others to pass it around, if you wanted. I like the idea of the mix of 80/20 and the Mdf.. or if they get posted up here or somwhere i will download them thakns. Chris

I am using 8020 for the frame of my router. On my Z-axis I am using 8020 bearings but not on my X & Y axis.

I would be willing to post the plans for download on my site http://studysession.com and post a link here in the thread if you want?

I am not the one with the plans. I was offering to host them for download since the file was to big to post here.

Cheers -

[Hack]

I would like to see the plans hosted somewhere, so I would be willing to take you up on the offer. Also, if anyone else is willing to as well that would be nice. Send me an email address.
