Great improvement for my 2x48

I got the tri platen attachement a couple of weeks ago, I don’t have a 84 but it fits perfectly, it would be great if you could choose the mesure of the arm as well but I made an attachment and works perfectly fine, a game changer for me that’s for sure

Kobie Rhodes
Awesome new platen

Fabulous build quality as always. Super useful with the different sized 3 wheels, the different slack-belt options, and MUCH better clearance on the LHS for grinding bevels, especially when clamped to 123 blocks. Love it.

Nick Allen
Shope mate 48 Tri Platen

Picked up the Tri Platen for my shop mate 48 grinder. Awesome addition to the grinder, adding not only the 4" wheel and the different choices of slack belt grinding that the tri Platen offers, but also gives more clearance on the left side of the platen from the tooling arm.
Love it!

Sam Heath
Shop Mate 48 Tri platen

I am really happy with the new shop mate 48 tri platen. The new design allows for more clearance on the left hand side which is great when using file guides. I love the ease and efficiency of the bonus four inch wheel, it really comes in handy when shaping handles.
A really great solid platen and a real improvement on the original.
Also I really appreciate the speed of which my order was processed. I received it three days after placing my order.
Keep up the great work thanks a lot.

I have been using 84 Engineering belt grinders for many years, it's truly the one tool that gets the most use in my garage building motorcycles, It's one of those tools that you wonder how you ever did without! I highly recommend anyone working with steel have one! Dan - Cafe Race Garage -YouTube
