How To Attach A Letter/number Stamp To An Arbor Press

[kevturbo]

Can anyone please help in clearing up just how to attach a letter/number stamp or hole punch to an arbor press. The internet indeed has no real guidance on how to go about this, and I am at my wits end trying to work it out for myself. if you can help me and other newbies out there understand this, then you would be helping a lot of people. As far as i can see, the end of the "arbor" is just a flat square, as per my picture attached, and there are no Youtube videos covering this point either.

Also, can I stamp a logo thats just over 2 inches long with an arbor press? And if so, how should I go about this please?

My first bridal leather hide arrived today, and it is a beautiful thing. I'm off to practice my strap cutting skills while I await any forthcoming help on this subject.

Thank you all in advance - this forum is a complete godsend to people like me...

Have not seen any videos on the process but have read plenty of articles and they all say that they take the rod/ram (Square piece) to a machine shop and have them drill two holes. One in the center of the ram/rod that will accept your tool, and one on the side that will accept a screw so that you can tighten the tool in place.

If you decide to drill them yourself, be sure to keep the drill bit square and plumb in relation to the ram or your impressions will be "deeper" on one of the sides. The hole in the bottom of the ram is for fitting the stamp handle in. The hole in the side of the ram will need to be tapped to accept the set screw that will hold the handle in position.

Good luck,

I had the ram drilled and threaded to accept a drill chuck.

For the stamp use a piece of plate steel the same size or slightly smaller on top of the stamp.

It will help distribute the pressure over a larger area.

Thank you all for your advice. iI will indeed find a machine shop somewhere to do as you all say. At this stage, and having been an office bound graphic designer, I do not possess the equipment or skills to drill, tap and die the rod arm myself. Also, I am not sure where to find a "machine shop" to do the task, but I will look into this.

As for stamping the longer logo, a piece of solid steel the width of the logo makes sense. Should I get a two ton press for this, as it is over 2 inches wide, or do you think a one ton would suffice?

Perhaps a Youtube video should be made by the Arbor Press manufacturers on this subject would help. Meanwhile this thread will surely help many people out there to achieve a little clarity on this issue.

Thank you all for your help once again so far

Bigger is better, you lose space when you start adding chucks, stamps and bases to stamp on.

A shop press is a better choice for a little more money.

Good advice. A few little tips: The hole in the end of the ram should be 3//8" in diameter. Not all tools are 3/8, but many if not most are. Those that are larger can be turned down to that diameter on a lathe. Those that are smaller will require a split bushing to bring their effective diameter to 3/8". I have my ram's side hole tapped for a thumb screw so I don't need a wrench to use it. But... I don't think even a 2-ton press will do the job on veg-tan with that large of a stamp. And, I know it won't work on bridle leather. You may need a hydraulic shop press for that.

I have used a 1 ton press on a plate 1.5 x 2.5" with no trouble.

The hole in the ram can be .5" dia. The side screw will always push the tool you are using over against the opposite side and stay aligned vertically in the ram. The place this won't work is if your bottom anvil or plate is fixed and centred. Then the top tool needs to always be centred too. Then you need a bushing like noted above.

Forget the hole, and have it milled like a vee block. That way you can clamp any diameter, and have it straight. I had posted this suggestion a few times.. I may have to mill one myself so that I can post a pic of what I mean.

I just bored a hole in mine (3/8 inch if I remember correctly) then cross drilled for a 1/4-20 set screw. Any diameter shaft that is not too large to fit can be clamped vertical, straight and solid to the side of the hole by the set screw. If bottom dies are used they are simply placed on the bottom plate and lined up with the ram manually so there is no need for bushings or adapters. I use mine mostly for setting snaps/grommets and stamping with 3d stamps. The handle for my hole punch is a little too snug a fit so I have considered taking the hole out to 1/2 inch but for now I just use my drill press to (not running) for punching holes.

I drilled the hole myself on an old and worn Harbor Freight drill press. Even with careful setup and attention to detail the first attempt came out less than perfect but thankfully there are two ends to the ram and my second attempt worked out just fine. The extra hole has caused no harm.
