So, lets say you're wanting to drill a 13mm hole into 20mm thick Bright mild steel on a bench top drill press. My approach for this has generally been : - Centre punch a mark to guide the drill - Have the piece clamped in a vice, but have the vice loose on the table so it can find it's place...

I've just noticed that Warco also sell it too. Warco are considered a respectable metal working brand, right? https://www.warco.co.uk/work-holding-tools-equipment/303439-compound-slide-table.html

Did you find an alternative?

Thought I'd post a picture of the finished job. Very pleased with it. Moves easily, and no detectable play.

There are 2 different products, 2 links for each one, for each website.

Where are you seeing that? I'm going by the table sizes, which are the same as far as I can see

Not really asking about the company. I know people have successfully bought from them. It's more about the product, and whether I'd be paying a fair bit more for the same thing.

I've noticed that both these companies sell what looks like the same product, but with a very different price tag. https://www.rdgtools.co.uk/acatalog/COMPOUND-MILLING-TABLE-185-X-150-10997.html#SID=88#SID=88...

Also, when I say "No vertical play", I mean specifically between the thrust bearings and their surrounding pieces. I am under no illusion that there will be some play in the jig as a whole. : )

Thank you for taking the time to make up drawings. I'm currently just going to go with the thrust washers as per Bob Chapmans post as it requires the least precision, and means I will have no vertical play (which is all that matters for my use case)

Thankyou for the idea, but this is basically what I already described in the first post. The problem is that for the bars to move freely, you have to have a little spacing (play) where you have the washers. And even the smallest amount of spacing makes the whole thing jiggle about (you'd be...

This is how the commercial ones work. There is a bearing seated in a blind hole, on the top and bottom of the middle bar. A washer then sits on the bearing (top and bottom) to space the top and bottom bar off the middle bar and allow them to rotate freely. A bolt then goes through with a lock...

Was it just Mild Steel? or Bright Mild steel?

Excellent, thanks!

Thanks. I'm aware of the Simon Hope one and the gate ones, but this one is different. And I had looked for guides on how to make one, but none of the ones I cam across used bearings, which was why I came here to ask.

Yep, if you read the first post, I explained why I was thinking about thrust bearings as they're much easier to apply without having to drill large accurate holes. I'll have a look at the ones you linked, but not sure I understand how you would use them in this scenario?

I had considered it, but figured Aluminium would be easier to work with? I thought 3030 was really strong? or do you mean it will vibrate because it's fairly light?

These were the ones I ordered AXK Axial Needle Roller Thrust Bearing AXK00619- AXK1730+2AS Washers Choose Size | eBay

That's exactly what it's for :) ..although not for "deep deep" hollowing .. just small project hollowing. It's more to hold the tool for me as I suffer from a bad back (I'm copying the Trent Bosch Stabilizer). I'd be happy to buy one, but he doesn't ship to the UK, so am trying to make one. The...

I've already ordered some to try 👍
